Abstract

Purpose. In many patients with epilepsy seizures occur with a day/night pattern. Our aims were to compare day/night patterns in seizure frequency among patients with different epileptogenic regions. Methods. We analyzed video-EEG recordings in 15 patients with temporal lobe (TLE) and 11 with extratemporal lobe epilepsy (XTLE). Each seizure was classified according to subject group (TLE vs XTLE), sleep/wake state, and time of day of seizure occurrence (grouped into 6 × 4-hour "bins"). Results. Of 90 seizures, 41 occurred in TLE and 49 in XTLE patients. There were day/night patterns of seizure occurrence in each group, with differences in the patterns between groups. In TLE, 50% of seizures occurred between the hours of 15:00 and 19:00 (17% would be expected by chance in each 4-hour "bin": F=3.59, P
