Signs Your Hospital Patient May Have Lost Some Mental Acuity

The role of the hospitalist is multidisciplinary and one of the primary responsibilities in your role is to notice and act on the changes you notice regarding your patients, including mental awareness and acuity.

"Evaluation of orientation and level of awareness is a core component of any hospitalist's daily evaluation," said Tara Scribner, MD, an internal medicine hospitalist, The University of Vermont Medical Center; associate program director for POCUS and Procedure Curriculum, UVMMC Internal Medicine Residency Program; and an assistant professor, Robert Larner, M.D. College of Medicine, Burlington, Vermont. "Beyond this, a broader assessment of executive function and functional abilities always occurs at some point during a hospital admission as discharge location and situation depends on this."

While it's relatively easy to identify signs of dementia using information from collateral sources, she also noted it's often difficult to determine whether a patient is experiencing progressive dementia or a more acute encephalopathy such as delirium if collateral sources are not available.

"Once a baseline has been established, hospitalists are in a unique position to identify subtle and acute shifts in mental acuity over the course of a hospital stay," Scribner said. "Unlike our primary care colleagues, who are well-positioned to observe for signs of dementia, we see our patients on a daily basis, sometimes more than once daily, and can track changes which occur over a matter of hours or days."

What Are Signs to Watch

During examinations and assessments, pay attention to shifts in the behavior of patients.

"Subtle signs of delirium and/or declining mental awareness can include disorientation about date, location, reason for admission," said Meghana R. Medavaram, MD, associate director of Consultation Liaison and Emergency Psychiatry, Weiler Hospital at Montefiore Health System in Bronx, New York.

Another sign would be mild inattention, such as drifting off during conversations or even having a hard time understanding and following multistep commands, she also said.

"We can also see sudden irritability or even the opposite, odd politeness or familiarity. We notice these changes occur as fluctuations throughout the day, sometimes with a clinician seeing a different 'personality' in the morning vs afternoon or evening," Medavaram said. "A key message we emphasize for our hospitalist colleagues is to not wait for overt agitation, or hallucinations to step in when assessing a patient and coming up with a treatment plan."

How Would Diet Play a Role

Excess consumption of alcohol is the most common way a patient's diet can affect changes in mental status, said Scribner. "Excess alcohol use has been linked to a significantly increased risk of dementia including both Alzheimer's and to alcohol-related brain damage including Korsakoff syndrome, as well as to the more acute Wernicke encephalopathy through vitamin B1 deficiency."

Also, vitamin deficiencies such as B12 have been linked to development of dementia and other cognitive impairment and can be related to alcohol consumption as well as to dietary habits such as vegetarianism, even in the absence of alcohol intake. Identification and treatment of B12 deficiency is a potentially reversible cause of cognitive impairment, she also said.

Do Medications Affect Mental State

Medications can be a significant cause of acute changes in mental status. "These changes are often reversible and include somnolence and both hypoactive and hyperactive delirium. Adjustment of a patient's usual medications is often necessary in hospitalized patients experiencing acute encephalopathy," Scribner said.

What About Depression

The relationship between dementia and development of dementia is complex and poorly understood, she said, however, those who deal with depression are at a higher risk of developing dementia, and also that patients with dementia are at a higher risk for development of depression.

How to Distinguish Between Short- and Long-term Issues

A thorough hospitalist is typically able to identify the acuity of mental status changes by the time of discharge and therefore predict the likelihood of recovery.

Progressive mental status changes occurring over months to years are almost always representative of dementia and are irreversible, whereas most (but not all) acute encephalopathies are recoverable over days to weeks or months.

Determining which of these is present involves interrogation of collateral sources such as family and friends, assessment of orientation and other signs of delirium, and observation of recovery during the period of hospital admission. It is worth noting that episodes of delirium are associated with a higher risk for long-term cognitive decline and development of dementia.
