dc.description.abstractBackground Due to their semiological similarities, psychogenic nonepileptic seizures (PNESs) can occasionally hardly be differentiated from epileptic seizures (ESs), and long-term video-electroencephalographic monitoring (VEM) is needed for the differential diagnosis.Objective To investigate the time of the first clinical event and its distribution on the days of VEM in ES and PNES patients.Methods In total, a consecutive series of 48 PNES and 51 ES patients matched for gender and age were retrospectively and consecutively evaluated. The time distribution of the seizures during the day was noted. Seizure latency was determined as the time in hours from the start of the video-electroencephalographic recording to the first clinical event.Results The seizure latency was significantly shorter in PNES patients compared to ES patients ( p < 0.001). Seventy-two percent of PNES patients and 49.1% of ES patients had their first seizure in the 24 hours of video-EEG recording ( p = 0.023). Recording longer than 48 hours was required for 12.5% of PNES patients and 37.3% of ES patients ( p = 0.006). While ESs were almost evenly distributed throughout the day, most PNESs occurred during the evening hours ( p = 0.011).Conclusion We observed that the PNESs appeared earlier than the ESs in the VEM and were concentrated during daylight hours. Although not strictly reliable, seizure latency can contribute to the differential diagnosis of ES and PNES.en_US
