For some medical students and trainees who go on to become hematologists, attraction to the field happens the first time they’re engrossed in figuring out what a blood smear is telling them. Others get drawn to hematology during a rotation in residency, when they encounter patients with hemophilia or sickle cell disease.

But when it comes to turning people on to the idea of a career in classical hematology (CH), there may be no more powerful influence than a mentor who loves their job. That’s why the field is focusing so much on supporting mentors and mentees amid a stark shortage of classical hematologists.

“Mentorship is key for maintaining trainee interest in the field and for providing role models for career growth,” said Rakhi P. Naik, MD, MHS, associate professor of medicine and director of the Hematology Fellowship Track at Johns Hopkins University, Baltimore, Maryland, in an interview. “This collaboration is especially critical because there are so few trainees and so few mentors currently in the field.”

Now there’s new research backing up the power of mentorship, even when it’s only provided virtually, and a brand-new program aims to unite more mentors and mentees.

Here’s a closer look at mentor-focused efforts to attract medical students to CH.

 

How Severe Is the Shortage in CH?

Patients with conditions treated by classical hematologists are waiting months for appointments at many outpatient centers, with some being forced to wait 6 months or more, said Srikanth Nagalla, MD, chief of benign hematology at Miami Cancer Institute, Florida, in an interview.

The shortage is creating dire problems in the inpatient setting too, Nagalla said. “Serious blood disorders like heparin-induced thrombocytopenia, acute chest syndrome [a complication of sickle cell disease], and thrombotic thrombocytopenic purpura have to be diagnosed and treated in a timely manner. If not, the morbidity and mortality are really high.”

If classical hematologists aren’t available, he said, oncologists and others not trained in hematology will need to cover these patients. 

Hematologist Ariela Marshall, MD, associate professor of medicine at the University of Minnesota in Minneapolis, noted in an interview that the CH shortage comes at a time when medical advances and an aging population are boosting the number of patients with noncancerous blood disorders. Older people are at greater risk for blood clots, she said. And lifespans for patients with bleeding and clotting disorders are rising thanks to effective new treatments.

“Because of our larger patient population in CH, we are going to need more classical hematologists to follow them for longer and longer periods of time,” she said. 

There’s no sign yet that newly minted physicians will take up the slack in CH. A 2019 study found that just 4.6% of 626 of hematology/oncology fellows said they planned to go into CH, also known as benign hematology, vs 67.1% who expected to treat patients with solid tumors, blood cancer, or both. The rest, 24.6%, planned to work in CH plus the two oncology fields.

 

Why Does a Shortage Exist?

“The reasons are complex, but one of the most important factors was the combining of the adult hematology and medical oncology training programs by the Accreditation Council for Graduate Medical Education in 1995,” Naik said. “After that time, the majority of fellowship training programs went from having separate programs for hematology and medical oncology to combining the training for the two specialties into one. Because most of these combined training programs resided within Cancer Centers, classical hematology training slowly became de-emphasized.”

As a result, fewer fellows ended up specializing in CH, she said. 

The field of CH also appears to suffer from a less than enticing reputation. According to a 2019 study coauthored by Marshall, surveys of thousands of hematology/oncology fellows found that “hematology, particularly benign hematology, was viewed as having poorer income potential, research funding, job availability, and job security than oncology.”

Regarding pay, Marshall said the good news is that many classical hematologists work in academia, where it’s common for pay to be “equitable across hematology/oncology divisions and based more on academic rank and other factors rather than subspecialty within hematology oncology.”

However, she noted, “this may differ at institutions where hematology and oncology are different departments. For example, centers where oncology is its own department, and hematology is part of the department of medicine.” 

As for job availability, Naik said that there’s plenty of demand. “In academics, it is clear that there are jobs available everywhere, but trainees are often worried about job prospects in private practice. While classical hematology jobs in private practice are not widely advertised, I can attest that there is no shortage of need,” she said. “Many private practices do not specifically advertise for classical hematologists because they assume that classical hematology experts are not available. But I assure you that every private practice my trainees have ever approached is always ecstatic to hire a classical hematologist.”

 

Why Are Mentors Important?

Mentorship is crucial to promoting the value of CH as a great career choice in a competitive environment, classical hematologists say. “We can motivate trainees by showing how the disease states themselves are so fascinating and how the treatments are showing great outcomes,” Nagalla said. “We can show positive results, how patient lives can be changed, and how well-respected across the system [we] are.”

As a selling point, classical hematologists like to emphasize that their field requires intensive detective work. “Let’s say a patient comes with anemia, which might have 15 different causes. You get some labs, and then you systemically rule in or rule out most of these on the differential diagnosis,” Nagalla said. “Then once you narrow it down, you get more labs. You keep going to the next step and next step, and so finally you come to a conclusion.”

As for therapy, Marshall said that “while for many cancers there are specific treatment recommendations for patients with a specific cancer type at a specific stage, there is not always a specific treatment recommendation (or a ‘right answer’) for our CH patients. Treatment planning depends strongly on a patient’s preferences, other medical conditions, and a discussion about risks [and] benefits of different treatment options such that two patients with the same condition may choose two different treatment options.”

Marshall also emphasizes to trainees that “CH is a broad field. Physicians and trainees are able to interact and collaborate with physicians in other specialties such as gastroenterology, cardiology, ob/gyn, and surgical specialties.” 

 

Does Research Support Mentorship in CH?

The 2019 study that revealed just 4.6% of fellows planned to go into CH found that “fellows who planned to enter hematology-only careers were significantly more likely to report having clinical training and mentorship experiences in hematology throughout their training relative to fellows with oncology-only or combined hematology/oncology career plans.”

Now there are more data to support mentorships. For a study published in Blood Advances in September 2024, Zoya Qureshy, MD, an internal medicine chief resident at the University of California at San Diego, and colleagues evaluated a year-long external membership program implemented by the American Society of Hematology (ASH) Medical Educators Institute. 

The program linked 35 US hematology/oncology fellows (80% female, 46% White, 35% Asian) who were interested in CH to 34 North American faculty members. The pairs were told to meet virtually once a month. 

Of 30 mentees and 23 mentors surveyed, 94% and 85%, respectively, said their pairings were good matches. Two thirds of the mentees accepted faculty positions in CH after their mentorships.

“Our study showed that external mentorship in a virtual format is feasible,” Qureshy said in an interview. “Additionally, external mentorship provided benefits such as different perspectives and the opportunity for mentorship for those who may not have it in their field of interest at their home institution.”

Qureshy added that “one strength of our mentorship program was that mentoring pairs were meticulously assigned based on shared interests and background. Many participants cited this common ground as a reason why they thought their mentoring pair was a good match.” 

There’s an important caveat: Most of the mentees weren’t new to CH. About 70% had previously worked with a mentor in the CH field, and 86% had previously conducted research in the field. 

 

What’s Next for Mentorship in CH?

The ASH Hematology-Focused Fellowship Training Program Consortium aims to mint 50 new academic hematologists by 2030 through programs at 12 institutions. “Mentorship is an exciting aspect of the program since it allows classical hematology trainees to form a network of peers nationally and also provides access to mentors across institutions,” Naik said. “And as the workforce grows, there will be more and more role models for future trainees to look up to.”

Moving forward, she said, “we hope to inspire even more institutions to adopt hematology training tracks throughout the country.”

Meanwhile, ASH’s new Classical Hematology Advancement Mentorship is taking applications for its debut 2025 program through January 9, 2025. Trainees will meet monthly with mentors both virtually and in person. Applicants must have been in their first or second year of hematology/oncology fellowship training at accredited programs in the United States as of July 15, 2024.

Naik, Marshall, Nagalla, and Qureshy have no relevant disclosures.

’Tis the season for recognizing seasonal affective disorder (SAD). Just don’t expect to find SAD in diagnostic handbooks.

As a memorable term, SAD “stuck in the general public, and to some extent among health professionals,” said Scott Patten, MD, PhD, professor of psychiatry and epidemiology at the University of Calgary in Alberta, Canada. “But it’s important to emphasize that that’s not an officially recognized diagnosis by the major classifications.”

Researchers coined the term SAD 40 years ago to describe a pattern of depression that sets in during the fall or winter and remits in the spring or summer.

Clinicians are diagnosing the disorder, albeit without that exact moniker.

In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), the condition is considered a subtype of major depression.

So, for patients who meet criteria for recurrent major depressive disorder, the specifier “with seasonal pattern” might be applied.

The subtype covers cases where depressive episodes have followed a seasonal pattern for at least 2 years. Typically, onset occurs in the fall or winter followed by remission in the spring or summer. The opposite pattern is possible but less common.

When stressors such as seasonal unemployment better explain the pattern, the seasonal specifier should not be used, according to the manual. Bipolar disorder can follow a seasonal pattern as well.

Researchers estimate SAD affects about 5% of adults in the United States. The diagnosis is more common in women than in men, and more prevalent farther from the equator.

 

One Hallmark Symptom?

DSM-5 highlights characteristic features of winter depression, including:

• Loss of energy
• Hypersomnia
• A craving for carbohydrates
• Overeating
• Weight gain

Kelly Rohan, PhD, a researcher at the University of Vermont, Burlington, who has studied SAD since the 1990s, sees one symptom as a possible hallmark for the disorder: fatigue.

“I’ve personally never met someone who met the full diagnostic criteria for the seasonal pattern that did not have fatigue as one of their symptoms,” Rohan said. “In theory, they could exist, but I have spoken to hundreds of people with seasonal depression, and I have never met them if, in fact, they do exist.”

That differs from nonseasonal depression, for which insomnia is a more common problem with sleep, Patten said.

Clinicians look for at least five symptoms of depression that cause substantial impairment and distress for at least 2 weeks, such as pervasive sadness, difficulty concentrating, low self-esteem, or loss of interest in hobbies.

An average episode of winter depression can last 5 months, however, Rohan said. “That’s a long time to be in a major depressive episode.”

 

Seeing Subsyndromal Cases

In people who do not meet criteria for major depression with a seasonal pattern, the change of seasons still can affect energy levels and mood. Some patients have “subsyndromal SAD” and may benefit from treatments that have been developed for SAD such as bright light therapy, said Paul Desan, MD, PhD, director of the Winter Depression Research Clinic at Yale School of Medicine in New Haven, Connecticut.

“Many people come to our clinic because they have seasonal changes that don’t meet the full criteria for depression, but nevertheless, they want help,” Desan said.

The 1984 paper that introduced the term SAD explored artificial bright light as a promising treatment for the condition. The researchers had heard from dozens of patients with “recurrent depressions that occur annually at the same time each year,” and bright light appeared to help alleviate their symptoms.

Subsequent trials have found the approach effective. Even in nonseasonal depression, bright light therapy may increase the likelihood of remission, a recent meta-analysis found. Light therapy also may bolster the effectiveness of antidepressant medication in nonseasonal major depressive disorder, a randomized trial has shown.

Other treatments for SAD include cognitive behavioral therapy (CBT) and bupropion XL, which is approved as a preventive medication. Other drugs for major depressive disorder may be used.

 

Quest for Biomarkers

To better understand SAD and how available treatments work, Rohan is conducting a study that examines potential biomarkers in patients treated with light therapy or CBT. She and her colleagues are examining circadian phase angle difference (how well internal clocks match daily routines) and post-illumination pupil response (how the pupil constricts after a light turns off). They also are measuring participants’ pupil responses and brain activity upon seeing words that are associated with winter or summer (like “blizzard,” “icy,” “sunshine,” and “picnics.”) 

Studies have shown treating patients to remission with CBT reduces the risk for recurrence in subsequent years, relative to other treatment approaches, Rohan said. That may be because CBT gives people tools to avoid slipping into another depressive episode.

 

Avoid Self-Diagnosis

Rohan cautions patients against self-diagnosis and treatment.

“Having a conversation with your doctor is a good starting point,” she said. “Just because you can walk into Costco and walk out with a light box doesn’t mean that you should.” 

Light therapy can have side effects, including headaches, eye strain, and making patients feel wired, and it can be a challenge to determine the right dose, Rohan said.

Desan’s clinic website provides information about available devices for light therapy for patients who are looking to try this approach, but Desan agrees clinicians — especially primary care clinicians — can play a crucial role in helping patients. In more serious cases, a mental health expert may be necessary.

To start light therapy, Desan’s clinic typically recommends patients try 30 minutes of 10,000 lux bright light — roughly the brightness of being outside on a sunny day — before 8 AM for a 4-week trial.

Still, other specific issues might explain why a patient is struggling during winter months, Patten said. For example, people might experience financial stress around the holidays or consume excessive amounts of alcohol during that time.

“It’s important for clinicians to think broadly about it,” Patten said. “It might not always be light therapy or a medication. It might be focusing on some other aspect of what is going on for them in the winter.” 

Rohan’s research is funded by the National Institute of Mental Health, and she receives royalties for a manual on treating SAD with CBT. Patten and Desan had no relevant financial disclosures.

Researchers estimate SAD affects about 5% of adults in the United States. The diagnosis is more common in women than in men, and more prevalent farther from the equator.

 

One Hallmark Symptom?

DSM-5 highlights characteristic features of winter depression, including:

• Loss of energy
• Hypersomnia
• A craving for carbohydrates
• Overeating
• Weight gain

Kelly Rohan, PhD, a researcher at the University of Vermont, Burlington, who has studied SAD since the 1990s, sees one symptom as a possible hallmark for the disorder: fatigue.

“I’ve personally never met someone who met the full diagnostic criteria for the seasonal pattern that did not have fatigue as one of their symptoms,” Rohan said. “In theory, they could exist, but I have spoken to hundreds of people with seasonal depression, and I have never met them if, in fact, they do exist.”

That differs from nonseasonal depression, for which insomnia is a more common problem with sleep, Patten said.

Clinicians look for at least five symptoms of depression that cause substantial impairment and distress for at least 2 weeks, such as pervasive sadness, difficulty concentrating, low self-esteem, or loss of interest in hobbies.

An average episode of winter depression can last 5 months, however, Rohan said. “That’s a long time to be in a major depressive episode.”

 

Seeing Subsyndromal Cases

In people who do not meet criteria for major depression with a seasonal pattern, the change of seasons still can affect energy levels and mood. Some patients have “subsyndromal SAD” and may benefit from treatments that have been developed for SAD such as bright light therapy, said Paul Desan, MD, PhD, director of the Winter Depression Research Clinic at Yale School of Medicine in New Haven, Connecticut.

“Many people come to our clinic because they have seasonal changes that don’t meet the full criteria for depression, but nevertheless, they want help,” Desan said.

The 1984 paper that introduced the term SAD explored artificial bright light as a promising treatment for the condition. The researchers had heard from dozens of patients with “recurrent depressions that occur annually at the same time each year,” and bright light appeared to help alleviate their symptoms.

Subsequent trials have found the approach effective. Even in nonseasonal depression, bright light therapy may increase the likelihood of remission, a recent meta-analysis found. Light therapy also may bolster the effectiveness of antidepressant medication in nonseasonal major depressive disorder, a randomized trial has shown.

Other treatments for SAD include cognitive behavioral therapy (CBT) and bupropion XL, which is approved as a preventive medication. Other drugs for major depressive disorder may be used.

 

Quest for Biomarkers

To better understand SAD and how available treatments work, Rohan is conducting a study that examines potential biomarkers in patients treated with light therapy or CBT. She and her colleagues are examining circadian phase angle difference (how well internal clocks match daily routines) and post-illumination pupil response (how the pupil constricts after a light turns off). They also are measuring participants’ pupil responses and brain activity upon seeing words that are associated with winter or summer (like “blizzard,” “icy,” “sunshine,” and “picnics.”) 

Studies have shown treating patients to remission with CBT reduces the risk for recurrence in subsequent years, relative to other treatment approaches, Rohan said. That may be because CBT gives people tools to avoid slipping into another depressive episode.

 

Avoid Self-Diagnosis

Rohan cautions patients against self-diagnosis and treatment.

“Having a conversation with your doctor is a good starting point,” she said. “Just because you can walk into Costco and walk out with a light box doesn’t mean that you should.” 

Light therapy can have side effects, including headaches, eye strain, and making patients feel wired, and it can be a challenge to determine the right dose, Rohan said.

Desan’s clinic website provides information about available devices for light therapy for patients who are looking to try this approach, but Desan agrees clinicians — especially primary care clinicians — can play a crucial role in helping patients. In more serious cases, a mental health expert may be necessary.

To start light therapy, Desan’s clinic typically recommends patients try 30 minutes of 10,000 lux bright light — roughly the brightness of being outside on a sunny day — before 8 AM for a 4-week trial.

Still, other specific issues might explain why a patient is struggling during winter months, Patten said. For example, people might experience financial stress around the holidays or consume excessive amounts of alcohol during that time.

“It’s important for clinicians to think broadly about it,” Patten said. “It might not always be light therapy or a medication. It might be focusing on some other aspect of what is going on for them in the winter.” 

Rohan’s research is funded by the National Institute of Mental Health, and she receives royalties for a manual on treating SAD with CBT. Patten and Desan had no relevant financial disclosures.

’Tis the season for recognizing seasonal affective disorder (SAD). Just don’t expect to find SAD in diagnostic handbooks.

As a memorable term, SAD “stuck in the general public, and to some extent among health professionals,” said Scott Patten, MD, PhD, professor of psychiatry and epidemiology at the University of Calgary in Alberta, Canada. “But it’s important to emphasize that that’s not an officially recognized diagnosis by the major classifications.”

Researchers coined the term SAD 40 years ago to describe a pattern of depression that sets in during the fall or winter and remits in the spring or summer.

Clinicians are diagnosing the disorder, albeit without that exact moniker.

In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), the condition is considered a subtype of major depression.

So, for patients who meet criteria for recurrent major depressive disorder, the specifier “with seasonal pattern” might be applied.

The subtype covers cases where depressive episodes have followed a seasonal pattern for at least 2 years. Typically, onset occurs in the fall or winter followed by remission in the spring or summer. The opposite pattern is possible but less common.

When stressors such as seasonal unemployment better explain the pattern, the seasonal specifier should not be used, according to the manual. Bipolar disorder can follow a seasonal pattern as well.

President-elect Donald Trump’s vision for the nation’s top health agencies is coming into focus with three nominations announced Nov. 22 that drew both criticism and praise:

• Surgeon and health researcher Martin A. Makary, MD, MPH, to lead the US Food and Drug Administration (FDA).
• Former Republican congressman and physician David J. Weldon, MD, for director of the US Centers for Disease Control and Prevention (CDC).
• Fox News contributor Janette Nesheiwat, MD, for surgeon general.

Earlier in November, Trump nominated vaccine skeptic and former presidential candidate Robert F. Kennedy Jr. to lead the US Department of Health and Human Services (HHS). 

Here’s what to know about the latest nominees, who, like Kennedy, must be confirmed by the US Senate.

 

Martin A. Makary

Currently a professor at the Johns Hopkins School of Medicine and chief of islet transplant surgery at Johns Hopkins Hospital, Makary co-invented in 2006 a surgery checklist that became a widely-used patient safety tool. 

As a US FDA commissioner, Makary would preside over a $6.5 billion agency with more than 18,000 employees. The agency, part of HHS, oversees human and animal drugs and vaccines, medical devices, food, tobacco and other products. Some of Makary’s views align closely with those of HHS nominee Kennedy. 

Makary is also chief medical officer of telehealth platform Sesame.

Makary was primarily known as a health researcher and author of books about price transparency and the cost of health care until the COVID-19 pandemic, when he became an outspoken critic of the federal response, lambasting restrictions and mandates advocated by the CDC and other public health officials. 

In 2023, Makary told the House Select Subcommittee on the COVID Pandemic that federal officials had ignored what he called “natural immunity.” Studies have shown that natural immunity is “at least as effective as vaccinated immunity, and probably better,” testified Makary.

Makary called for an overhaul of the US FDA in a 2021 Fox News opinion, saying that its culture was “defined by counterproductive rigidity and a refusal to adapt.”

Blind Spots, his most recent book, takes on what he calls “medical dogma” and challenges conventional views on subjects ranging from the microbiome to marijuana to cancer prevention, hormone replacement therapy, antibiotics and peanut allergies.

In an interview he posted to X, Makary blames inappropriate use of antibiotics for a variety of childhood illnesses. He cites increases in obesity, learning disabilities, attention deficit disorder, asthma, celiac disease, ulcerative colitis and Crohn’s disease as all potentially causally related to antibiotics given in childhood.

Makary is an advisor to two conservative think tanks, the Foundation for Research on Equal Opportunity, and to Paragon Health Institute, begun in 2021 by two former top officials in the previous Trump administration.

Makary would “cut the bureaucratic red tape at the agency to make sure Americans get the medical cures and treatments they deserve,” Trump said on his social media platform, Truth Social, and in a press release.

While Los Angeles Times owner and physician-entrepreneur Patrick Soon-Shiong, MBBCh, MSc, praised the nomination of Makary (and the two other nominees) as “inspired,” other physicians criticized Makary for his anti-COVID mandate views and “fear-mongering” over COVID vaccine side effects.

 

Janette Nesheiwat

As surgeon general, Nesheiwat would serve as the top “health communicator in chief” and oversee the 6000 member US Public Health Service Commissioned Corps.

She is a frequent medical contributor to Fox News and serves as a medical director for a group of urgent care clinics in New York. She received her medical degree from the American University of the Caribbean School of Medicine and completed a family medicine residency at the University of Arkansas for Medical Sciences. She is board-certified in family medicine.

Nesheiwat sells vitamin supplements on her website and in December will publish a book on “miracles in medicine” and her Christian faith. 

Trump said in a statement that Nesheiwat “is a fierce advocate and strong communicator for preventive medicine and public health. She is committed to ensuring that Americans have access to affordable, quality healthcare, and believes in empowering individuals to take charge of their health to live longer, healthier lives.”

While Nesheiwat was critical of COVID mandates, she voiced more support for COVID vaccines and mask-wearing during the pandemic than her fellow nominees, leading some Trump supporters to criticize her nomination. 

“A good appointment, happy about this: I got to know @DoctorJanette during the pandemic, exchanging information. She is very smart, thoughtful, interested in learning, and a compassionate doctor, and…a truly nice person,” noted vaccine researcher Peter Hotez, MD, PhD, said on X.

 

David J. Weldon

If confirmed, former congressman Weldon would oversee the sprawling CDC, an agency with a roughly $17 billion budget, 15,000 employees or contractors, and numerous centers covering everything from health statistics to vaccines to epidemiology.

After earning his medical degree from the University at Buffalo School of Medicine, Weldon served in the US Army and US Army reserve. The Republican later served for 14 years in Congress representing Florida’s 15th district, which covers the Tampa region.

He now practices as an internist in Brevard County, Florida.

In Congress, Weldon raised concerns about the safety of some vaccines and promoted the false narrative that a former vaccine ingredient, thimerosal, caused autism, the Washington Post reported. Thimerosal has not been used in child vaccines for more than two decades. He also introduced a bill to move vaccine safety oversight from the CDC to an independent agency within HHS.

Trump said in a statement that Weldon “will proudly restore the CDC to its true purpose, and will work to end the Chronic Disease Epidemic.” 

But some physicians criticized Weldon for what they called his anti-vaccine views.

Suicide and self-harm continue to be serious concerns in Europe, despite decreasing rates over the past two decades. In 2021 alone, 47,346 people died by suicide in the European Union, close to 1% of all deaths reported that year. Measures have been taken at population, subpopulation, and individual levels to prevent suicide and suicide attempts. But can more be done? Yes, according to experts.

Researchers are investigating factors that contribute to suicide at the individual level, as well as environmental and societal pressures that may increase risk. New predictive tools show promise in identifying individuals at high risk, and ongoing programs offer hope for early and ongoing interventions. Successful preventive strategies are multimodal, emphasizing the need for trained primary care and mental health professionals to work together to identify and support individuals at risk at every age and in all settings.

 

‘Radical Change’ Needed

The medical community’s approach to suicide prevention is all wrong, according to Igor Galynker, MD, PhD, clinical professor of psychiatry and director of the Mount Sinai Suicide Prevention Research Lab in New York City. 

Galynker is collaborating with colleagues in various parts of the world, including Europe, to validate the use of suicide crisis syndrome (SCS) as a diagnosis to help imminent suicide risk evaluation and treatment.

SCS is a negative cognitive-affective state associated with imminent suicidal behavior in those who are already at high risk for suicide. Galynker and his colleagues want to see SCS recognized and accepted as a suicide-specific diagnosis in the Diagnostic and Statistical Manual of Mental Disorders and the World Health Organization’s International Classification of Diseases. 

Currently, he explained to this news organization, clinicians depend on a person at risk for suicide telling them that this is what they are feeling. This is “absurd,” he said, because people in this situation are in acute pain and distress and cannot answer accurately.

“It is the most lethal psychiatric condition, because people die from it ... yet we rely on people at the worst moment of their lives to tell us accurately when and how they are going to kill themselves. We don’t ask people with serious mental illness to diagnose their own mental illness and rely on that diagnosis.”

Data show that most people who attempt or die by suicide deny suicidal thoughts when assessed by healthcare providers using current questionnaires and scales. Thus, there needs to be “a radical change” in how patients at acute risk are assessed and treated to help “prevent suicides and avoid lost opportunities to intervene,” he said.

Galynker explained that SCS is the final and most acute stage of the “ narrative crisis model” of suicide, which reflects the progression of suicidal risk from chronic risk factors to imminent suicidal risk. “The narrative crisis model has four distinct and successive stages, with specific guidance and applicable interventions that enable patients to receive a stage-specific treatment.”

“Suicide crisis syndrome is a very treatable syndrome that rapidly resolves” with appropriate interventions, he said. “Once it is treated, the patient can engage with psychotherapy and other treatments.”

Galynker said he and his colleagues have had encouraging results with their studies so far on the subjective and objective views of clinicians using the risk assessment tools they are developing to assess suicidal ideation. Further studies are ongoing. 

 

Improving Prediction

There is definitely room for improvement in current approaches to suicide prevention, said Raffaella Calati, PhD, assistant professor of clinical psychology at the University of Milano-Bicocca, Italy, who has had research collaborations with Galynker.

Calati advocates for a more integrated approach across disciplines, institutions, and the community to provide an effective support network for those at risk. 

Accurately predicting suicide risk is challenging, she told this news organization. She and colleagues are working to develop more precise predictive tools for identifying individuals at risk, often by leveraging artificial intelligence and data analytics. They have designed and implemented app-based interventions for psychiatric patients at risk for suicide and university students with psychological distress. The interventions are personalized and based on multiple approaches, such as cognitive-behavioral therapy (CBT) and third-wave CBT. 

The results of current studies are preliminary, she acknowledged, “but even if apps are extremely complex, our projects received high interest from participants and the scientific community,” she said. The aim now is to integrate these tools into healthcare systems so that monitoring high-risk patients becomes part of regular care. 

Another area of focus is the identification of specific subtypes of individuals at risk for suicide, particularly by examining factors such as pain, dissociation, and interoception — the ability to sense and interpret internal signals from the body. 

“By understanding how these experiences intersect and contribute to suicide risk, I aim to identify distinct profiles within at-risk populations, which could ultimately enable more tailored and effective prevention efforts,” she said.

Her work also involves meta-research to build large, comprehensive datasets that increase statistical power for exploring suicide risk factors, such as physical health conditions and symptoms associated with borderline personality disorder. By creating these datasets, she aims to “improve understanding of how various factors contribute to suicide risk, ultimately supporting more effective prevention strategies.”

 

Country-Level Efforts

Preventive work is underway in other countries as well. In Nordic countries such as Denmark, Finland, and Sweden, large-scale national registries that track people’s medical histories, prescriptions, and demographic information are being used to develop predictive algorithms that identify those at high risk for suicide. The predictions are based on known risk factors like previous mental health diagnoses, substance abuse, and social determinants of health.

A recent Norwegian study found that a novel assessment tool used at admission to an acute inpatient unit was a powerful predictor of suicide within 3 years post-discharge.

Researchers in the Netherlands have also recently co-designed a digital integrated suicide prevention program, which has led to a significant reduction in suicide mortality. 

SUPREMOCOL (suicide prevention by monitoring and collaborative care) was implemented in Noord-Brabant, a province in the Netherlands that historically had high suicide rates. It combines technology and personal care, allowing healthcare providers to track a person’s mental health, including by phone calls, text messages, and mobile apps that help people express their feelings and report any changes in their mental state. By staying connected, the program aims to identify warning signs early and provide timely interventions.

The results from the 5-year project showed that rates dropped by 21.5%, from 14.4 per 100,000 to 11.8 per 100,000, and remained low, with a rate of 11.3 per 100,000 by 2021.

Finland used to have one of the highest suicide rates in the world. Now it is implementing its suicide prevention program for 2020-2030, with 36 proposed measures to prevent suicide mortality. 

The program includes measures such as increasing public awareness, early intervention, supporting at-risk groups, developing new treatment options, and enhancing research efforts. Earlier successful interventions included limiting access to firearms and poison, and increasing use of antidepressants and other targeted interventions.

“A key is to ensure that the individuals at risk of suicide have access to adequate, timely, and evidence-based care,” said Timo Partonen, MD, research professor at the Finnish Institute for Health and Welfare and associate professor of psychiatry at the University of Helsinki.

“Emergency and frontline professionals, as well as general practitioners and occupational health physicians, have a key role in identifying people at risk of suicide,” he noted. “High-quality competencies will be developed for healthcare professionals, including access to evidence-based suicide prevention models for addressing and assessing suicide risk.” 

 

Global Strategies

Policymakers across Europe are increasingly recognizing the importance of enhanced public health approaches to suicide prevention. 

The recently adopted EU Action Plan on Mental Health emphasizes the need for comprehensive suicide prevention strategies across Europe, including the promotion of mental health literacy and the provision of accessible mental health services.

The plan was informed by initiatives such as the European Alliance Against Depression (EAAD)-Best project, which ran from 2021 until March 2024. The collaborative project brought together researchers, healthcare providers, and community organizations to improve care for patients with depression and to prevent suicidal behavior in Europe. 

The multimodal approach included community engagement and training for healthcare professionals, as well as promoting the international uptake of the iFightDepression tool, an internet-based self-management approach for patients with depression. It has shown promise in reducing suicide rates in participating regions, including Europe, Australia, South America, and Africa.

“What we now know is that multiple interventions produce a synergic effect with a tendency to reduce suicidal behavior,” said EAAD founding member Ricardo Gusmão, MD, PhD, professor of public mental health at the University of Porto, Portugal. Current approaches to suicide prevention globally vary widely, with “many, fragmentary, atomized interventions, and we know that none of them, in isolation, produces spectacular results.” 

Gusmão explained that promising national suicide prevention strategies are based on multicomponent community interventions. On the clinical side, they encompass training primary health and specialized mental health professionals, and have a guaranteed chain of care and functioning pathways for access. They also involve educational programs in schools, universities, prisons, work settings, and geriatric care centers. Additionally, they have well-developed good standards for media communication and health marketing campaigns on well-being and mental health literacy.

Relevant and cohesive themes for successful strategies include the promotion of positive mental health, the identification and available treatments for depression and common mental disorders, and the management of suicidal crisis stigma. 

“We are now focusing on workplace settings and vulnerable groups such as youth, the elderly, unemployed, migrants and, of course, people affected by mental disorders,” he said. “Suicide prevention is like a web that must be weaved by long-lasting efforts and intersectoral collaboration.”

“Even one suicide is one too many,” Brendan Kelly, MD, PhD, professor of psychiatry, Trinity College Dublin, and author of The Modern Psychiatrist’s Guide to Contemporary Practice, told this news organization. “Nobody is born wanting to die by suicide. And every suicide is an individual tragedy, not a statistic. We need to work ever more intensively to reduce rates of suicide. All contributions to research and fresh thinking are welcome.”

Galynker, Calati, Partonen, and Kelly have disclosed no relevant financial relationships.  Gusmão has been involved in organizing Janssen-funded trainings for registrars on suicidal crisis management.

Suicide and self-harm continue to be serious concerns in Europe, despite decreasing rates over the past two decades. In 2021 alone, 47,346 people died by suicide in the European Union, close to 1% of all deaths reported that year. Measures have been taken at population, subpopulation, and individual levels to prevent suicide and suicide attempts. But can more be done? Yes, according to experts.

Researchers are investigating factors that contribute to suicide at the individual level, as well as environmental and societal pressures that may increase risk. New predictive tools show promise in identifying individuals at high risk, and ongoing programs offer hope for early and ongoing interventions. Successful preventive strategies are multimodal, emphasizing the need for trained primary care and mental health professionals to work together to identify and support individuals at risk at every age and in all settings.

 

‘Radical Change’ Needed

The medical community’s approach to suicide prevention is all wrong, according to Igor Galynker, MD, PhD, clinical professor of psychiatry and director of the Mount Sinai Suicide Prevention Research Lab in New York City. 

Galynker is collaborating with colleagues in various parts of the world, including Europe, to validate the use of suicide crisis syndrome (SCS) as a diagnosis to help imminent suicide risk evaluation and treatment.

SCS is a negative cognitive-affective state associated with imminent suicidal behavior in those who are already at high risk for suicide. Galynker and his colleagues want to see SCS recognized and accepted as a suicide-specific diagnosis in the Diagnostic and Statistical Manual of Mental Disorders and the World Health Organization’s International Classification of Diseases. 

Currently, he explained to this news organization, clinicians depend on a person at risk for suicide telling them that this is what they are feeling. This is “absurd,” he said, because people in this situation are in acute pain and distress and cannot answer accurately.

“It is the most lethal psychiatric condition, because people die from it ... yet we rely on people at the worst moment of their lives to tell us accurately when and how they are going to kill themselves. We don’t ask people with serious mental illness to diagnose their own mental illness and rely on that diagnosis.”

Data show that most people who attempt or die by suicide deny suicidal thoughts when assessed by healthcare providers using current questionnaires and scales. Thus, there needs to be “a radical change” in how patients at acute risk are assessed and treated to help “prevent suicides and avoid lost opportunities to intervene,” he said.

Galynker explained that SCS is the final and most acute stage of the “ narrative crisis model” of suicide, which reflects the progression of suicidal risk from chronic risk factors to imminent suicidal risk. “The narrative crisis model has four distinct and successive stages, with specific guidance and applicable interventions that enable patients to receive a stage-specific treatment.”

“Suicide crisis syndrome is a very treatable syndrome that rapidly resolves” with appropriate interventions, he said. “Once it is treated, the patient can engage with psychotherapy and other treatments.”

Galynker said he and his colleagues have had encouraging results with their studies so far on the subjective and objective views of clinicians using the risk assessment tools they are developing to assess suicidal ideation. Further studies are ongoing. 

 

Improving Prediction

There is definitely room for improvement in current approaches to suicide prevention, said Raffaella Calati, PhD, assistant professor of clinical psychology at the University of Milano-Bicocca, Italy, who has had research collaborations with Galynker.

Calati advocates for a more integrated approach across disciplines, institutions, and the community to provide an effective support network for those at risk. 

Accurately predicting suicide risk is challenging, she told this news organization. She and colleagues are working to develop more precise predictive tools for identifying individuals at risk, often by leveraging artificial intelligence and data analytics. They have designed and implemented app-based interventions for psychiatric patients at risk for suicide and university students with psychological distress. The interventions are personalized and based on multiple approaches, such as cognitive-behavioral therapy (CBT) and third-wave CBT. 

The results of current studies are preliminary, she acknowledged, “but even if apps are extremely complex, our projects received high interest from participants and the scientific community,” she said. The aim now is to integrate these tools into healthcare systems so that monitoring high-risk patients becomes part of regular care. 

Another area of focus is the identification of specific subtypes of individuals at risk for suicide, particularly by examining factors such as pain, dissociation, and interoception — the ability to sense and interpret internal signals from the body. 

“By understanding how these experiences intersect and contribute to suicide risk, I aim to identify distinct profiles within at-risk populations, which could ultimately enable more tailored and effective prevention efforts,” she said.

Her work also involves meta-research to build large, comprehensive datasets that increase statistical power for exploring suicide risk factors, such as physical health conditions and symptoms associated with borderline personality disorder. By creating these datasets, she aims to “improve understanding of how various factors contribute to suicide risk, ultimately supporting more effective prevention strategies.”

 

Country-Level Efforts

Preventive work is underway in other countries as well. In Nordic countries such as Denmark, Finland, and Sweden, large-scale national registries that track people’s medical histories, prescriptions, and demographic information are being used to develop predictive algorithms that identify those at high risk for suicide. The predictions are based on known risk factors like previous mental health diagnoses, substance abuse, and social determinants of health.

A recent Norwegian study found that a novel assessment tool used at admission to an acute inpatient unit was a powerful predictor of suicide within 3 years post-discharge.

Researchers in the Netherlands have also recently co-designed a digital integrated suicide prevention program, which has led to a significant reduction in suicide mortality. 

SUPREMOCOL (suicide prevention by monitoring and collaborative care) was implemented in Noord-Brabant, a province in the Netherlands that historically had high suicide rates. It combines technology and personal care, allowing healthcare providers to track a person’s mental health, including by phone calls, text messages, and mobile apps that help people express their feelings and report any changes in their mental state. By staying connected, the program aims to identify warning signs early and provide timely interventions.

The results from the 5-year project showed that rates dropped by 21.5%, from 14.4 per 100,000 to 11.8 per 100,000, and remained low, with a rate of 11.3 per 100,000 by 2021.

Interest is growing in the role of nutrition as means of slowing, or even preventing, neurodegeneration in patients with Parkinson’s disease.

For 15 years, John Duda, MD, national director of the VA Parkinson’s Disease Research, Education and Clinical Centers, has urged his patients to “keep waiting” for effective treatments to manage both motor and nonmotor symptoms of Parkinson’s disease.

However, Duda, who also serves as director of the Brain Wellness Clinic at the Corporal Michael J. Crescenz VA Medical Center in Philadelphia, Pennsylvania, recognized the persistent lack of effective drugs to address these symptoms. This prompted him to consider what other evidence-based strategies he could use to support his patients. 

“I recognized that nutritional approaches within a broader program that includes medication review, stress management, social connections, adequate sleep, and physical exercise could make a real difference,” he said.

Observational studies have shown an inverse association between dietary patterns and Parkinson’s disease risk, age of onset, symptom severity, and mortality rates — particularly with the Mediterranean diet (MeDi) and the MIND diet, which combines elements of MeDi and the Dietary Approaches to Stop Hypertension (DASH) diet. Although randomized controlled trials are still limited, the epidemiologic evidence supporting dietary interventions is “compelling,” said Duda. 

For example, a cross-sectional study comparing 167 participants with Parkinson’s disease vs 119 controls showed that later age of Parkinson’s disease onset correlated with adherence to the MIND diet in women, with a difference of up to 17.4 years (P < .001) between low and high dietary tertiles. 

The MeDi was correlated with later onset in men, with differences of up to 8.4 years (P = .002). As previously reported, a healthy diet emphasizing vegetables, fruits, nuts, and grains was inversely associated with prodromal features of Parkinson’s disease, including constipation, excessive daytime sleepiness, and depression. In addition, lower rates of Parkinson’s disease have been shown in populations following vegetarian and vegan dietary patterns. 

 

Does Parkinson’s disease Start in the Gut?

Parkinson’s disease is characterized by decreased short-chain fatty acid–producing bacteria and increased pro-inflammatory species linked to intestinal inflammation and alpha-synuclein aggregation. “There are reasons to believe that a-synuclein accumulation may start in the gut,” Duda noted.

Numerous studies implicate gut microbiome dysbiosis as a pathogenic mechanism in Parkinson’s disease, with gastrointestinal symptoms often predating motor symptoms. Dysbiosis might result in a pro-inflammatory state potentially linked to the recurrent gastrointestinal symptoms. Fecal microbiota transplant may restore a healthier gut environment and beneficially affect Parkinson’s disease symptoms, he said.

Some of the benefits conferred by the MeDi and other healthy diets may be mediated by improving the gut microbiome. Duda cited a study that showed that a 14-day ovo-lacto vegetarian diet intervention and a daily fecal enema for 8 days improved not only the microbiome but also Movement Disorder Society Unified Parkinson’s Disease Rating Scale—part III scores. 

Duda also reviewed the role of dietary interventions in addressing common Parkinson’s disease symptoms, such as orthostatic hypotension. He recommended that Parkinson’s disease patients with this condition should avoid eating large meals, increase dietary salt intake, increase fluid intake, and decrease alcohol intake.

Malnutrition affects close to 25% of those with Parkinson’s disease, which is partially attributable to diminished olfaction. Because the experience of taste is largely driven by a sense of smell, patients may be less interested in eating. Duda recommended increasing herbs, spices, and other flavors in food. High caloric–density foods, including nuts, nut butters, and seeds, can boost weight, he said. However, he added, any patient with significant weight loss should consult a nutritionist.

Constipation is one of the most debilitating symptoms of Parkinson’s disease, affecting up to 66% of patients. Duda advised increasing fluid intake, exercise, and dietary fiber and use of stool softeners and laxatives. The MeDi may reduce symptoms of constipation and have a beneficial effect on gut microbiota. 

Coffee may be helpful for sleepiness in Parkinson’s disease and may also confer neuroprotective, motor, and cognitive benefits. As an adjuvant treatment, caffeine may alter levodopa pharmacokinetics, reduce dyskinesia, improve gait in patients with freezing and may even reduce the risk of developing Parkinson’s disease, with a maximum benefit reached at approximately three cups of coffee daily.

 

Problematic Foods

There is also a growing body of evidence regarding the deleterious effects of ultraprocessed foods (UPFs), Duda said. He noted that a recent systematic review and meta-analysis of 28 studies showed that higher UPF intake was significantly associated with an enhanced risk for Parkinson’s disease (relative risk, 1.56; 95% CI, 1.21-2.02). As previously reported, UPFs have been tied to a host of adverse neurologic outcomes, including cognitive decline and stroke. 

Although protein is a necessary nutrient, incorporating it into the diet of Parkinson’s disease patients taking levodopa is complicated. Levodopa, a large neutral amino acid (LNAA), competes with other LNAAs for transport to the brain from the small intestine, Duda explained. 

“Some people notice that carbidopa-levodopa doesn’t work as well if taken with a high-protein meal.” He recommended taking carbidopa-levodopa 30 minutes before or 60 minutes after meals.

Rebecca Gilbert, MD, PhD, chief mission officer of the American Parkinson’s Disease Association, said that patients with Parkinson’s disease might want to avoid eating protein during the day, concentrating instead on carbohydrates and vegetables and saving the protein for the evening, which is closer to bedtime. Some evidence also supports the use of protein redistribution diets to enhance the clinical response to levodopa and reduce motor fluctuations. 

 

What About Supplements? 

It’s “hard to prove that one specific supplement can be protective against Parkinson’s disease because diet consists of many different components and the whole diet may be worth more than the sum of its parts,” Gilbert said. The evidence for individual supplements “isn’t robust enough to say they prevent or treat Parkinson’s disease.”

Research on the role of specific nutrients in Parkinson’s disease is conflicting, with no clear evidence supporting or refuting their benefits. For example, a study that followed participants for about 30 years showed no link between reduced Parkinson’s disease risk and vitamin B or folate intake. 

On the other hand, there is research suggesting that certain vitamins may help reduce Parkinson’s disease risk, although these nutrients do not operate in isolation. For instance, one recent study showed a connection between vitamins C and E and reduced Parkinson’s disease risk, but factors such as body mass index and coffee consumption appeared to influence the strength of this association.

Consuming polyunsaturated fatty acids along with reducing saturated fatty acid intake has been tied to a reduced risk for Parkinson’s disease. 

Additionally, certain foods may offer protective effects, including green and black tea, with consumption of three or more cups per day associated with a delay in motor symptom onset by 7.7 years. Foods high in nicotine content, such as those from the Solanaceae family — including peppers, tomatoes, tomato juice, and potatoes — have also been linked to potential protective benefits.

Diets rich in antioxidants, including carotenoids, lutein, and vitamins E and C, have been robustly linked to a reduced risk for parkinsonism and progression of parkinsonian symptoms in older adults.

Increasing the intake of dietary flavonoids, particularly tea, berry fruits, apples, red wine, and oranges or orange juice, can reduce Parkinson’s disease risk. One study showed that male participants in the highest quintile of total flavonoid consumption had a 40% lower Parkinson’s disease risk compared with those in the lowest quintile. Another study showed that flavonoid-rich foods were also associated with a lower risk for death in patients with Parkinson’s disease. 

 

Food as Medicine 

Although recent research shows that the drug development pipeline for Parkinson’s disease is robust, with a wide variety of approaches being developed and evaluated in phase 1 and 2, investigators note that only a limited number of disease-modifying treatments are transitioning to phase 3.

Duda noted that phytochemicals incorporated into the diet might target some of the same mechanisms that are targets of these drugs in development. 

“Flavonoids have been shown to stabilize alpha-synuclein in vitro,” he said. “Caffeine, curcumin, resveratrol, and eliminating meat and dairy inhibit mTOR [mammalian target of rapamycin], and mTOR inhibition results in increased autophagy that may help clear alpha-synuclein. Genestein, an isoflavone in soybeans, protects dopaminergic neurons by inhibiting microglia activation. Flavonoids inhibit inflammation by inhibiting release of NO [nitric oxide] and pro-inflammatory cytokines,” he noted. 

Ongoing studies of dietary interventions for Parkinson’s disease are exploring various areas, including the potential role of the ketogenic diet in protecting the gut microbiome, optimizing protein intake for muscle preservation and sleep, the effects of psyllium and wheat bran on weight and constipation, and the impact of a gluten-free diet.

 

Practical Tips for Healthy Eating 

Gilbert emphasized that there are no medications or interventions currently available that can delay a Parkinson’s disease diagnosis by up to 17 years, as some dietary patterns have been shown to do, and she noted that it’s not possible to replicate the MeDi diet in a pill. However, she recommended a practical approach to eating that includes a diet low in ultraprocessed foods and high in beneficial nutrients. She encouraged people to shop for “real food” and enjoy a variety of colorful fruits and vegetables.

Duda acknowledged that motivating patients to follow a healthy diet can be difficult. As a result, the focus often shifts to making small adjustments and modifications. For example, he suggested that instead of pairing meat with French fries, people could opt for vegetables or add greens to their meals. Similarly, instead of having eggs and bacon for breakfast, they might choose oatmeal.

Preparing whole-food, plant-based meals may take more time than patients are accustomed to, so Duda suggests that, if possible, patients involve loved ones in both the meal preparation and the meal itself. He explained that a healthy meal can become an opportunity for bonding and that the key is educating them about new meal-related concepts. 

Duda reported no relevant financial relationships with the pharmaceutical or food industries. He has received compensation from the Physicians Committee for Responsible Medicine for his lecture delivered at the conference and research grant support from the VA, the National Institutes of Health, the Michael J. Fox Foundation, and the Department of Defense unrelated to this topic. Gilbert reported no relevant financial relationships.

This prompted him to consider what other evidence-based strategies he could use to support his patients. 

“I recognized that nutritional approaches within a broader program that includes medication review, stress management, social connections, adequate sleep, and physical exercise could make a real difference,” he said.

Observational studies have shown an inverse association between dietary patterns and Parkinson’s disease risk, age of onset, symptom severity, and mortality rates — particularly with the Mediterranean diet (MeDi) and the MIND diet, which combines elements of MeDi and the Dietary Approaches to Stop Hypertension (DASH) diet. Although randomized controlled trials are still limited, the epidemiologic evidence supporting dietary interventions is “compelling,” said Duda. 

For example, a cross-sectional study comparing 167 participants with Parkinson’s disease vs 119 controls showed that later age of Parkinson’s disease onset correlated with adherence to the MIND diet in women, with a difference of up to 17.4 years (P < .001) between low and high dietary tertiles. 

The MeDi was correlated with later onset in men, with differences of up to 8.4 years (P = .002). As previously reported, a healthy diet emphasizing vegetables, fruits, nuts, and grains was inversely associated with prodromal features of Parkinson’s disease, including constipation, excessive daytime sleepiness, and depression. In addition, lower rates of Parkinson’s disease have been shown in populations following vegetarian and vegan dietary patterns. 

 

Does Parkinson’s disease Start in the Gut?

Parkinson’s disease is characterized by decreased short-chain fatty acid–producing bacteria and increased pro-inflammatory species linked to intestinal inflammation and alpha-synuclein aggregation. “There are reasons to believe that a-synuclein accumulation may start in the gut,” Duda noted.

Numerous studies implicate gut microbiome dysbiosis as a pathogenic mechanism in Parkinson’s disease, with gastrointestinal symptoms often predating motor symptoms. Dysbiosis might result in a pro-inflammatory state potentially linked to the recurrent gastrointestinal symptoms. Fecal microbiota transplant may restore a healthier gut environment and beneficially affect Parkinson’s disease symptoms, he said.

Some of the benefits conferred by the MeDi and other healthy diets may be mediated by improving the gut microbiome. Duda cited a study that showed that a 14-day ovo-lacto vegetarian diet intervention and a daily fecal enema for 8 days improved not only the microbiome but also Movement Disorder Society Unified Parkinson’s Disease Rating Scale—part III scores. 

Duda also reviewed the role of dietary interventions in addressing common Parkinson’s disease symptoms, such as orthostatic hypotension. He recommended that Parkinson’s disease patients with this condition should avoid eating large meals, increase dietary salt intake, increase fluid intake, and decrease alcohol intake.

Malnutrition affects close to 25% of those with Parkinson’s disease, which is partially attributable to diminished olfaction. Because the experience of taste is largely driven by a sense of smell, patients may be less interested in eating. Duda recommended increasing herbs, spices, and other flavors in food. High caloric–density foods, including nuts, nut butters, and seeds, can boost weight, he said. However, he added, any patient with significant weight loss should consult a nutritionist.

Constipation is one of the most debilitating symptoms of Parkinson’s disease, affecting up to 66% of patients. Duda advised increasing fluid intake, exercise, and dietary fiber and use of stool softeners and laxatives. The MeDi may reduce symptoms of constipation and have a beneficial effect on gut microbiota. 

Coffee may be helpful for sleepiness in Parkinson’s disease and may also confer neuroprotective, motor, and cognitive benefits. As an adjuvant treatment, caffeine may alter levodopa pharmacokinetics, reduce dyskinesia, improve gait in patients with freezing and may even reduce the risk of developing Parkinson’s disease, with a maximum benefit reached at approximately three cups of coffee daily.

 

Problematic Foods

There is also a growing body of evidence regarding the deleterious effects of ultraprocessed foods (UPFs), Duda said. He noted that a recent systematic review and meta-analysis of 28 studies showed that higher UPF intake was significantly associated with an enhanced risk for Parkinson’s disease (relative risk, 1.56; 95% CI, 1.21-2.02). As previously reported, UPFs have been tied to a host of adverse neurologic outcomes, including cognitive decline and stroke. 

Although protein is a necessary nutrient, incorporating it into the diet of Parkinson’s disease patients taking levodopa is complicated. Levodopa, a large neutral amino acid (LNAA), competes with other LNAAs for transport to the brain from the small intestine, Duda explained. 

“Some people notice that carbidopa-levodopa doesn’t work as well if taken with a high-protein meal.” He recommended taking carbidopa-levodopa 30 minutes before or 60 minutes after meals.

Rebecca Gilbert, MD, PhD, chief mission officer of the American Parkinson’s Disease Association, said that patients with Parkinson’s disease might want to avoid eating protein during the day, concentrating instead on carbohydrates and vegetables and saving the protein for the evening, which is closer to bedtime. Some evidence also supports the use of protein redistribution diets to enhance the clinical response to levodopa and reduce motor fluctuations. 

 

What About Supplements? 

It’s “hard to prove that one specific supplement can be protective against Parkinson’s disease because diet consists of many different components and the whole diet may be worth more than the sum of its parts,” Gilbert said. The evidence for individual supplements “isn’t robust enough to say they prevent or treat Parkinson’s disease.”

Research on the role of specific nutrients in Parkinson’s disease is conflicting, with no clear evidence supporting or refuting their benefits. For example, a study that followed participants for about 30 years showed no link between reduced Parkinson’s disease risk and vitamin B or folate intake. 

On the other hand, there is research suggesting that certain vitamins may help reduce Parkinson’s disease risk, although these nutrients do not operate in isolation. For instance, one recent study showed a connection between vitamins C and E and reduced Parkinson’s disease risk, but factors such as body mass index and coffee consumption appeared to influence the strength of this association.

Consuming polyunsaturated fatty acids along with reducing saturated fatty acid intake has been tied to a reduced risk for Parkinson’s disease. 

Additionally, certain foods may offer protective effects, including green and black tea, with consumption of three or more cups per day associated with a delay in motor symptom onset by 7.7 years. Foods high in nicotine content, such as those from the Solanaceae family — including peppers, tomatoes, tomato juice, and potatoes — have also been linked to potential protective benefits.

Diets rich in antioxidants, including carotenoids, lutein, and vitamins E and C, have been robustly linked to a reduced risk for parkinsonism and progression of parkinsonian symptoms in older adults.

Increasing the intake of dietary flavonoids, particularly tea, berry fruits, apples, red wine, and oranges or orange juice, can reduce Parkinson’s disease risk. One study showed that male participants in the highest quintile of total flavonoid consumption had a 40% lower Parkinson’s disease risk compared with those in the lowest quintile. Another study showed that flavonoid-rich foods were also associated with a lower risk for death in patients with Parkinson’s disease. 

 

Food as Medicine 

Although recent research shows that the drug development pipeline for Parkinson’s disease is robust, with a wide variety of approaches being developed and evaluated in phase 1 and 2, investigators note that only a limited number of disease-modifying treatments are transitioning to phase 3.

Duda noted that phytochemicals incorporated into the diet might target some of the same mechanisms that are targets of these drugs in development. 

“Flavonoids have been shown to stabilize alpha-synuclein in vitro,” he said. “Caffeine, curcumin, resveratrol, and eliminating meat and dairy inhibit mTOR [mammalian target of rapamycin], and mTOR inhibition results in increased autophagy that may help clear alpha-synuclein. Genestein, an isoflavone in soybeans, protects dopaminergic neurons by inhibiting microglia activation. Flavonoids inhibit inflammation by inhibiting release of NO [nitric oxide] and pro-inflammatory cytokines,” he noted. 

Ongoing studies of dietary interventions for Parkinson’s disease are exploring various areas, including the potential role of the ketogenic diet in protecting the gut microbiome, optimizing protein intake for muscle preservation and sleep, the effects of psyllium and wheat bran on weight and constipation, and the impact of a gluten-free diet.

 

Practical Tips for Healthy Eating 

Gilbert emphasized that there are no medications or interventions currently available that can delay a Parkinson’s disease diagnosis by up to 17 years, as some dietary patterns have been shown to do, and she noted that it’s not possible to replicate the MeDi diet in a pill. However, she recommended a practical approach to eating that includes a diet low in ultraprocessed foods and high in beneficial nutrients. She encouraged people to shop for “real food” and enjoy a variety of colorful fruits and vegetables.

Duda acknowledged that motivating patients to follow a healthy diet can be difficult. As a result, the focus often shifts to making small adjustments and modifications. For example, he suggested that instead of pairing meat with French fries, people could opt for vegetables or add greens to their meals. Similarly, instead of having eggs and bacon for breakfast, they might choose oatmeal.

Preparing whole-food, plant-based meals may take more time than patients are accustomed to, so Duda suggests that, if possible, patients involve loved ones in both the meal preparation and the meal itself. He explained that a healthy meal can become an opportunity for bonding and that the key is educating them about new meal-related concepts. 

Duda reported no relevant financial relationships with the pharmaceutical or food industries. He has received compensation from the Physicians Committee for Responsible Medicine for his lecture delivered at the conference and research grant support from the VA, the National Institutes of Health, the Michael J. Fox Foundation, and the Department of Defense unrelated to this topic. Gilbert reported no relevant financial relationships.

Interest is growing in the role of nutrition as means of slowing, or even preventing, neurodegeneration in patients with Parkinson’s disease.

For 15 years, John Duda, MD, national director of the VA Parkinson’s Disease Research, Education and Clinical Centers, has urged his patients to “keep waiting” for effective treatments to manage both motor and nonmotor symptoms of Parkinson’s disease.

However, Duda, who also serves as director of the Brain Wellness Clinic at the Corporal Michael J. Crescenz VA Medical Center in Philadelphia, Pennsylvania, recognized the persistent lack of effective drugs to address these symptoms.

Just a few years after some TikTok videos spiked the demand, one in eight US adults has tried Ozempic (semaglutide) or another drug in its class. Glucagon-like peptide 1 (GLP-1) receptor agonist medications have revolutionized obesity medicine.

But they’re not without problems. In the early days of the social media craze, news reports often featured patients whose gastrointestinal side effects sent them to the emergency room (ER).

“It happened a lot then. Patients didn’t want to complain because they were losing weight, and they wound up in the ER with extreme constipation or a small bowel obstruction,” said Caroline Apovian, MD, co-director of the Center for Weight Management and Wellness at Brigham and Women’s Hospital and professor of medicine at Harvard Medical School, Boston.

“But that’s not really happening now,” she added.

Research backs up her assertion: A recent clinical review of studies found that many patients still experience side effects, but only at a mild to moderate level, while the dosage increases — and the unpleasantness tapers with time. Roughly 7% of patients discontinue the medications due to these symptoms.

Here’s what the latest research shows about GLP-1s’ side effects.

 

Most Common: Gastrointestinal Issues

Depending on the symptom and the specific drug, anywhere from one third to one half of patients will experience some kind of stomach trouble.

• In that clinical review, which looked at studies of three GLP-1 medications — semaglutide (Ozempic, Wegovy, Rybelsus), liraglutide (Saxenda, Victoza), and tirzepatide (Mounjaro, Zepbound) — semaglutide users fared comparatively worse.
• Nausea was reported most frequently — 44.2% of semaglutide users dealt with it, compared with 40.2% for liraglutide and 31% for tirzepatide. Diarrhea, constipation, and vomiting also struck one quarter to one third of semaglutide patients, and slightly fewer for the other two medications.

Apovian finds that careful dosage helps her patients avoid the worst effects.

“We don’t know who’s going to do well and who’s not,” she said. “We start slowly, and usually things go OK.”

If a patient does react poorly, she’ll hold off on increasing the dosage until they acclimate and advise using over-the-counter meds like MiraLAX to address the symptoms.

Few documented severe adverse gastro events appeared in the data, affecting less than 1% of liraglutide and tirzepatide patients and 2.6% of semaglutide users. The majority of these events were gallbladder-related.

 

Questions About Causation: Depression and Suicidality

About a year ago, a study used 18 years’ worth of data from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) to examine how often patients reported suicidal ideation and/or depression while using GLP-1 medications. Compared with metformin and insulin, researchers found disproportionate reporting by patients using semaglutide and liraglutide. Other GLP-1 medications didn’t show this effect. The researchers pointed out: These statistics don’t show causation — there’s no clear reason why those two medications were linked to more reports.

Further research has been more reassuring:

• Another study also used FAERS but looked only at data from 2018 to 2022, when usage of these drugs was ramping up, and found no link between suicidal or self-injurious behaviors and GLP-1.
• A recent cohort study, which looked at data from nearly 300,000 people, found that GLP-1 users aren’t at increased risk for death by suicide.
• Both the FDA and the European Medicines Agency have issued statements that the evidence doesn’t support a causal association.

There are several factors at play here. People with obesity and diabetes are more likely to have depression to begin with. And more importantly, even if there is a link, causality remains unclear. For instance, patients who lose weight via bariatric surgery are at increased risk for depression, substance abuse, and self-harm. These symptoms may be related to the weight loss itself, not the medications.

“Some people use food as something other than nutrition. They use food to soothe other psychological issues,” Apovian said. “When that’s taken away, the psychological issues are still there.”

In her practice, she’s seen the risk for mental health issues rise with more substantial weight loss — 50-100 pounds.

This lack of clarity regarding causation means it’s important to perform a detailed patient history before prescribing, so you can monitor more closely with preexisting psychiatric disorders.

 

Possible Link: Ocular Symptoms

Here, too, the research isn’t definitive but leans toward no clear association. Several studies have looked for a link between GLP-1 and vision-related issues:

• One examined FAERS data and network pharmacology and found semaglutide and lixisenatide were significantly associated with adverse events like blurred vision, visual impairment, and diabetic retinopathy.
• This summer, a cohort study of almost 17,000 people with diabetes or overweight/obesity suggested a link between semaglutide and nonarteritic anterior ischemic optic neuropathy (NAION), a common cause of blindness due to optic nerve damage. The study found “a substantially increased risk of NAION among individuals prescribed semaglutide relative to those prescribed other medications to treat type 2 diabetes and obesity or overweight.”
• But this month, another cohort study with 135,000 participants looked at NAION in people with type 2 diabetes, obesity, or both. It compared results with common non-GLP-1 medications and found just the opposite: No increased risk for NAION.

One drawback with all these studies is that they’re based on large databases rather than randomized controlled trials (RCTs). When researchers focused on RCTs in a 2023 meta-analysis, they found a significant association with only one form of GLP-1, albiglutide — which was withdrawn from the market in 2017. The other six FDA-approved drugs didn’t show a statistically significant link.

 

Possible Trouble: Pulmonary Aspiration Under Sedation

Earlier this month, the FDA updated labeling for semaglutide, liraglutide, and tirzepatide to include a warning about the risk for aspiration during surgery. While there are no published studies, several case reports have appeared.

GLP-1 medications delay gastric emptying, so even though a patient may have fasted before surgery as usual, some food or liquid may remain. In response to this possibility, a group of professional medical societies issued guidelines for using these medications during the perioperative period. They include:

• Consideration of dosage, symptoms, and other medical conditions: The risk is higher during the escalation phase, and in general, higher doses mean higher risk.
• Potential discontinuation of GLP-1 usage when assessment shows an elevated risk.
• Assessment on the day of the procedure for possible delayed gastric emptying.
• Preoperative dietary modifications, which might include switching to a liquid diet.

Rare: Serious Effects

And then there are the outliers, the frightening issues that make headlines. On their own, none of these are common enough to affect consideration of GLP-1 use:

• Studies in rats suggested an increased risk for thyroid cancer, but subsequent research has found no evidence.
• Colonic ischemia in association with tirzepatide.
• Acute pancreatitis leading to death in association with semaglutide.
• Speaking of pancreatitis, that clinical review of studies did find that both liraglutide and semaglutide led to an elevated risk for pancreatitis, bowel obstruction, and gastroparesis. But the numbers were so small as to be insignificant — for instance, just 0.2% of patients experienced pancreatitis.

Benefits Outweigh Risks

When you lay out these side effects against the countless known benefits of weight loss and blood sugar management — the lower risk for high blood pressure, heart disease, stroke, metabolic syndrome, fatty liver disease, several cancers, and more — the advantages of GLP-1 drugs seem clear. Ultimately, of course, it’s the patient’s decision whether to begin and continue taking any medication for a chronic disease.

Apovian recommends having in-depth conversations before you write that first prescription – she compares the situation to using an antihypertensive drug. If your patient understands potential side effects, they’re more likely to maintain long-term compliance.

“We educate our patients how to use these drugs, indefinitely, if you want to maintain a lower, healthier body weight,” she said. “I don’t see patients who stop using them, but they’re out there. These are people desperate to lose weight, who aren’t given the education to understand we’re treating a disease. It’s not a matter of willpower.”

And once a patient starts taking a GLP-1, monitor them closely, with in-person visits rather than telehealth, while increasing the dosage. If they experience side effects, stay at that level until they ease. And if the patient has a good weight-loss response at a lower dose, stay there. Just because you can go higher, it doesn’t mean you should.

• One examined FAERS data and network pharmacology and found semaglutide and lixisenatide were significantly associated with adverse events like blurred vision, visual impairment, and diabetic retinopathy.
• This summer, a cohort study of almost 17,000 people with diabetes or overweight/obesity suggested a link between semaglutide and nonarteritic anterior ischemic optic neuropathy (NAION), a common cause of blindness due to optic nerve damage. The study found “a substantially increased risk of NAION among individuals prescribed semaglutide relative to those prescribed other medications to treat type 2 diabetes and obesity or overweight.”
• But this month, another cohort study with 135,000 participants looked at NAION in people with type 2 diabetes, obesity, or both. It compared results with common non-GLP-1 medications and found just the opposite: No increased risk for NAION.

One drawback with all these studies is that they’re based on large databases rather than randomized controlled trials (RCTs). When researchers focused on RCTs in a 2023 meta-analysis, they found a significant association with only one form of GLP-1, albiglutide — which was withdrawn from the market in 2017. The other six FDA-approved drugs didn’t show a statistically significant link.

 

Possible Trouble: Pulmonary Aspiration Under Sedation

Earlier this month, the FDA updated labeling for semaglutide, liraglutide, and tirzepatide to include a warning about the risk for aspiration during surgery. While there are no published studies, several case reports have appeared.

GLP-1 medications delay gastric emptying, so even though a patient may have fasted before surgery as usual, some food or liquid may remain. In response to this possibility, a group of professional medical societies issued guidelines for using these medications during the perioperative period. They include:

• Consideration of dosage, symptoms, and other medical conditions: The risk is higher during the escalation phase, and in general, higher doses mean higher risk.
• Potential discontinuation of GLP-1 usage when assessment shows an elevated risk.
• Assessment on the day of the procedure for possible delayed gastric emptying.
• Preoperative dietary modifications, which might include switching to a liquid diet.

Rare: Serious Effects

And then there are the outliers, the frightening issues that make headlines. On their own, none of these are common enough to affect consideration of GLP-1 use:

• Studies in rats suggested an increased risk for thyroid cancer, but subsequent research has found no evidence.
• Colonic ischemia in association with tirzepatide.
• Acute pancreatitis leading to death in association with semaglutide.
• Speaking of pancreatitis, that clinical review of studies did find that both liraglutide and semaglutide led to an elevated risk for pancreatitis, bowel obstruction, and gastroparesis. But the numbers were so small as to be insignificant — for instance, just 0.2% of patients experienced pancreatitis.

Benefits Outweigh Risks

When you lay out these side effects against the countless known benefits of weight loss and blood sugar management — the lower risk for high blood pressure, heart disease, stroke, metabolic syndrome, fatty liver disease, several cancers, and more — the advantages of GLP-1 drugs seem clear. Ultimately, of course, it’s the patient’s decision whether to begin and continue taking any medication for a chronic disease.

Apovian recommends having in-depth conversations before you write that first prescription – she compares the situation to using an antihypertensive drug. If your patient understands potential side effects, they’re more likely to maintain long-term compliance.

“We educate our patients how to use these drugs, indefinitely, if you want to maintain a lower, healthier body weight,” she said. “I don’t see patients who stop using them, but they’re out there. These are people desperate to lose weight, who aren’t given the education to understand we’re treating a disease. It’s not a matter of willpower.”

And once a patient starts taking a GLP-1, monitor them closely, with in-person visits rather than telehealth, while increasing the dosage. If they experience side effects, stay at that level until they ease. And if the patient has a good weight-loss response at a lower dose, stay there. Just because you can go higher, it doesn’t mean you should.

Just a few years after some TikTok videos spiked the demand, one in eight US adults has tried Ozempic (semaglutide) or another drug in its class. Glucagon-like peptide 1 (GLP-1) receptor agonist medications have revolutionized obesity medicine.

But they’re not without problems. In the early days of the social media craze, news reports often featured patients whose gastrointestinal side effects sent them to the emergency room (ER).

“It happened a lot then. Patients didn’t want to complain because they were losing weight, and they wound up in the ER with extreme constipation or a small bowel obstruction,” said Caroline Apovian, MD, co-director of the Center for Weight Management and Wellness at Brigham and Women’s Hospital and professor of medicine at Harvard Medical School, Boston.

“But that’s not really happening now,” she added.

Research backs up her assertion: A recent clinical review of studies found that many patients still experience side effects, but only at a mild to moderate level, while the dosage increases — and the unpleasantness tapers with time. Roughly 7% of patients discontinue the medications due to these symptoms.

Here’s what the latest research shows about GLP-1s’ side effects.

 

Most Common: Gastrointestinal Issues

Depending on the symptom and the specific drug, anywhere from one third to one half of patients will experience some kind of stomach trouble.

• In that clinical review, which looked at studies of three GLP-1 medications — semaglutide (Ozempic, Wegovy, Rybelsus), liraglutide (Saxenda, Victoza), and tirzepatide (Mounjaro, Zepbound) — semaglutide users fared comparatively worse.
• Nausea was reported most frequently — 44.2% of semaglutide users dealt with it, compared with 40.2% for liraglutide and 31% for tirzepatide. Diarrhea, constipation, and vomiting also struck one quarter to one third of semaglutide patients, and slightly fewer for the other two medications.

Apovian finds that careful dosage helps her patients avoid the worst effects.

“We don’t know who’s going to do well and who’s not,” she said. “We start slowly, and usually things go OK.”

If a patient does react poorly, she’ll hold off on increasing the dosage until they acclimate and advise using over-the-counter meds like MiraLAX to address the symptoms.

Few documented severe adverse gastro events appeared in the data, affecting less than 1% of liraglutide and tirzepatide patients and 2.6% of semaglutide users. The majority of these events were gallbladder-related.

 

Questions About Causation: Depression and Suicidality

About a year ago, a study used 18 years’ worth of data from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) to examine how often patients reported suicidal ideation and/or depression while using GLP-1 medications. Compared with metformin and insulin, researchers found disproportionate reporting by patients using semaglutide and liraglutide. Other GLP-1 medications didn’t show this effect. The researchers pointed out: These statistics don’t show causation — there’s no clear reason why those two medications were linked to more reports.

Further research has been more reassuring:

• Another study also used FAERS but looked only at data from 2018 to 2022, when usage of these drugs was ramping up, and found no link between suicidal or self-injurious behaviors and GLP-1.
• A recent cohort study, which looked at data from nearly 300,000 people, found that GLP-1 users aren’t at increased risk for death by suicide.
• Both the FDA and the European Medicines Agency have issued statements that the evidence doesn’t support a causal association.

There are several factors at play here. People with obesity and diabetes are more likely to have depression to begin with. And more importantly, even if there is a link, causality remains unclear. For instance, patients who lose weight via bariatric surgery are at increased risk for depression, substance abuse, and self-harm. These symptoms may be related to the weight loss itself, not the medications.

“Some people use food as something other than nutrition. They use food to soothe other psychological issues,” Apovian said. “When that’s taken away, the psychological issues are still there.”

In her practice, she’s seen the risk for mental health issues rise with more substantial weight loss — 50-100 pounds.

This lack of clarity regarding causation means it’s important to perform a detailed patient history before prescribing, so you can monitor more closely with preexisting psychiatric disorders.
