Retrospective Analysis of Video-EEG Findings and Clinical Characteristics in Adult Patients With Psychogenic Nonepileptic Seizures
Retrospective Analysis of Video-EEG Findings and Clinical Characteristics in Adult Patients With Psychogenic Nonepileptic Seizures
This completed retrospective observational study evaluated adult patients diagnosed with psychogenic nonepileptic seizures (PNES) who underwent video-EEG monitoring. Video-EEG records and clinical data of 50 adult patients were reviewed to describe semiological, electroclinical, and demographic characteristics of PNES. The study aimed to improve the understanding of video-EEG findings in PNES and to support accurate diagnosis in clinical practice.
Psychogenic nonepileptic seizures (PNES) are paroxysmal events that resemble epileptic seizures but are not associated with ictal epileptiform activity on EEG. Video-EEG monitoring is considered the reference standard for diagnosis. In this retrospective observational study, video-EEG recordings and clinical files of 50 adult patients with PNES were reviewed after completion of clinical care. Demographic data, clinical presentation, and video-EEG characteristics were analyzed descriptively. No intervention was assigned as part of the study. The purpose was to characterize the video-EEG and clinical profile of adult PNES patients evaluated in routine practice.
