PNES
Pronunciation: P-N-E-S
Also written as: PNES — psychogenic non-epileptic seizures
Psychogenic non-epileptic seizures, events that resemble epileptic seizures but are not caused by abnormal brain electrical activity.
Full Definition
Psychogenic non-epileptic seizures (PNES) are paroxysmal episodes that clinically resemble epileptic seizures but are not associated with abnormal electrical discharges in the brain. These events are psychological in origin and may be related to stress, trauma, anxiety, or conversion disorders. In pediatric populations, PNES can be challenging to differentiate from true epileptic seizures, particularly in adolescents where the condition is more common than in younger children. Video-EEG monitoring is often necessary for definitive diagnosis, as the clinical presentation may be quite convincing. Treatment focuses on addressing underlying psychological factors rather than antiepileptic medications. Distinguishing PNES from epileptic seizures is crucial to avoid inappropriate medical treatment and ensure appropriate psychological intervention.
Usage
Usage note: Avoid the outdated term 'pseudoseizures' which has negative connotations. PNES is the preferred terminology.
