PNES
Pronunciation: P-N-E-S
Also written as: PNES — Psychogenic Non-Epileptic Seizures
Psychogenic non-epileptic seizures; episodes that resemble epileptic seizures but lack abnormal electrical brain activity.
Full Definition
PNES are episodes that appear similar to epileptic seizures but are not caused by abnormal electrical brain activity. These events are typically related to psychological stress, trauma, or other psychiatric conditions. Diagnosis requires video-EEG monitoring to demonstrate normal brain waves during episodes. PNES can coexist with true epilepsy, complicating diagnosis and treatment. Management involves psychiatric care, psychotherapy, and gradual withdrawal of antiepileptic drugs. The condition was formerly called pseudoseizures, but this term is now discouraged due to its stigmatizing implications.
Usage
Usage note: Preferred term over 'pseudoseizures' which is considered stigmatizing; always spell out on first use.
