Few data are available on the diagnostic yield of sleep EEG recordings in elderly subjects with epilepsy. We assessed, and quantified by the calculation of a spike index (SI), the occurrence of interictal epileptiform abnormalities (IEAs) during ambulatory EEG monitorings (A-EEGs) recorded before treatment in 20 epilepsy outpatients whit onset at the age of ≥ 60 years. These findings were compared with those collected in patients with epilepsy onset at the age of 25-39 or 40-55 years. We found a significant increase of IEAs during deep NREM sleep (stages 3-4) in elderly subjects. Focal sleep-related IEAs in elderly patients with cryptogenetic epilepsy showed a peculiar morphologic and topographical pattern.
