NCT07521761

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Semiological subtype of PNES events

    Classification of PNES events recorded during video-EEG monitoring into semiological clusters (pauci-kinetic, hyperkinetic, hyperventilation-eye closure) based on ictal features.

    Baseline retrospective chart and video-EEG review

Secondary Outcomes (1)

  • Presence/absence of some events during PNES events
