Study on the Rapid Diagnostic Value of Sudden Clap Provocation Test in Psychogenic Nonepileptic Seizures

To explore the clinical value of the sudden clap provocation test in the differential diagnosis between epileptic seizures and psychogenic non-epileptic seizures, so as to provide a new strategy for rapid, low-cost differential diagnosis. This study is a prospective, single-center, diagnostic trial. This study is a single-center, prospective study that plans to recruit 400 patients who have "convulsive seizure" events during video electroencephalogram monitoring. A standardized sudden clap test is adopted, and one sudden clap test is performed during each clinically detected seizure episode, with the study period covering the entire VEEG monitoring process (approximately 24 hours). During the trial, the patient's basic treatment plan and VEEG monitoring process remain unchanged, and data analysis and diagnostic efficacy evaluation will be carried out after the VEEG monitoring is completed.
