NCT07526467 | Completed

• 1 other identifier: semenaveeg
• Study Type: observational
• Target: 50

Brief Summary

This retrospective observational study evaluates semiological and electroclinical characteristics of psychogenic nonepileptic seizures (PNES) in adult patients who underwent video-EEG monitoring. The study aims to identify distinct semiological patterns and classify PNES events based on observable ictal features recorded during video-EEG monitoring.

Conditions

Pnes

Outcome Measures

Primary Outcomes (1)

• Semiological cluster classification of PNES events

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

  Baseline (retrospective video-EEG analysis)

Secondary Outcomes (1)

• pnes events

  baseline

Study Arms (1)

patients

patients with pnes underwent video eeg monitoring

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

This study population consists of adult patients diagnosed with psychogenic nonepileptic seizures (PNES) who underwent long-term video-EEG monitoring in a tertiary epilepsy center. All included patients had at least one recorded PNES event and sufficient clinical data available for retrospective analysis. Patients were identified through medical records and video-EEG databases, and no interventions were performed as part of the study.

You may qualify if:

• Adults aged 18 years and older Diagnosis of psychogenic nonepileptic seizures (PNES) confirmed by video-EEG monitoring Availability of complete video-EEG recordings capturing at least one typical event Availability of sufficient clinical and demographic data in medical records for retrospective evaluation

You may not qualify if:

• Patients younger than 18 years Incomplete or poor-quality video-EEG recordings Absence of recorded typical PNES events during video-EEG monitoring Insufficient clinical documentation for retrospective analysis
