Prevalence data that may help address diagnostic and therapeutic challenges


 

References

Researchers examined 1567 patient medical records from the Vanderbilt University Medical Center Adult EMU and found a 5.2% prevalence rate of coexisting epilepsy/psychogenic nonepileptic spells (PNES). Other findings include:

· Epileptic seizures were preceded by a PNES event in 94.4% of epilepsy/PNES patients

· Patients with epilepsy/PNES had a higher presence of epilepsy risk factors

· Abnormal brain MRI and abnormal neurological examination were more common in the epilepsy/PNES group.
