PNES
Pronunciation: P-N-E-S
Also written as: PNES — psychogenic non-epileptic seizures
Psychogenic non-epileptic seizures; episodes resembling epileptic seizures but caused by psychological factors rather than abnormal brain electrical activity.
Full Definition
Psychogenic non-epileptic seizures (PNES) are paroxysmal events that superficially resemble epileptic seizures but are not associated with epileptiform discharges on EEG. These episodes are manifestations of underlying psychological distress or psychiatric conditions. PNES can be particularly challenging in pediatric populations where differential diagnosis from true epilepsy requires careful video-EEG monitoring. The condition often coexists with genuine epilepsy, complicating clinical management and requiring multidisciplinary approaches involving neurology, psychiatry, and psychology.
Usage
Usage note: Avoid stigmatizing language; emphasize that PNES are real medical events requiring appropriate treatment.
