Intubation for Psychogenic Non-Epileptic Attacks: Frequency, Risk Factors, and Impact on Outcome

Psychogenic non-epileptic attacks (PNEA) are defined as paroxysmal movements or abnormal behaviors that resemble epileptic seizures, are not accompanied by epileptiform activity, and are often associated with psychogenic factors. [1,2]. Documented clinical signs of PNEA without accompanying epileptiform activity on video electroencephalography (vEEG) is typically required to definitively confirm the diagnosis of PNEA. [1–3] Approximately 30% of hospitalized patients who undergo elective vEEG monitoring in epilepsy referral centers are diagnosed with PNEA.[4,5] We used the term “psychogenic nonepileptic attacks (PNEA)” instead of the term “psychogenic nonepileptic seizures (PNES)” or “dissociative seizures” because we want to make a clear differentiation of these events from epileptic seizures.
