Videopolysomnography with expanded electroencephalography (VEEG PSG) combines expanded EEG and PSG to evaluate unexplained paroxysmal nocturnal events. VEEG PSG can also provide a more comprehensive assessment of patients with neurologic disorders undergoing PSG. VEEG PSG has several advantages over routine PSG, including (1) improving the likelihood of recognizing interictal and ictal EEG activity; (2) allowing for more precise evaluation of EEG background; and (3) correlating clinical with other neurophysiologic parameters. This article reviews epileptic EEG abnormalities encountered when evaluating patients with unexplained nocturnal events in the sleep laboratory and discusses strategies to optimize the diagnostic yield of EEG and videorecordings.
