The purpose of this study was to investigate the duration of monitoring, number of seizures recorded, and date and time of occurrence of seizures in different patient groups during video-EEG monitoring (VEEGM). Patients with partial or psychogenic seizures who were admitted to our VEEGM unit between September 1996 and March 2002 were retrospectively evaluated. Duration of monitoring, date and time of occurrence of seizures were identified in each patient. For practical reasons, a day was divided into 3 equal time periods (period I: 08-16; period II: 16-24 and period III: 24-08 hrs), and the period in which the seizure occurred was noted. Patients were classified in 5 groups: 1 temporal; 2-frontal; 3-parieto-occipital; 4-psychogenic and 5-unclassified. Duration of monitoring, the number of seizures recorded and time distribution of seizures were identified in each group and compared statistically.
