The spectrum of complex motor behaviors that can occur during sleep is wide. These phenomena include epileptic seizures and parasomnias both from non-rapid eye movement (NREM) such as disorders of arousal (DOA) and from rapid eye movement (REM) sleep such as REM sleep behavior disorders (RBD).
The syndrome previously known as nocturnal frontal lobe epilepsy, recently named sleep-related hypermotor epilepsy (SHE), is recognized worldwide and has been studied in a wide range of clinical and scientific settings (epilepsy, sleep medicine, neurosurgery, pediatric neurology, epidemiology, genetics). Though uncommon, it is of considerable interest to practicing neurologists because of the complexity in differential diagnosis from more common parasomnias.
NREM sleep parasomnias are fascinating disorders presenting with a variety of bizarre behaviors and motor activity. They include sleepwalking, sleep terrors and confusional arousals - collectively termed disorders of arousal (DOA) - as well as less well-known entities such as sleep-related sexual behaviors and eating disorders. These conditions are common and sometimes severe, with social, personal and forensic implications. The diagnostic distinction between epileptic and non-epileptic behaviors arising from sleep may represent a significant challenge also for sleep specialists.
This collection of articles in Sleep Science and Practice aims to present in detail the most recent advances in the clinical and semiological features description of sleep-related epileptic and non-epileptic motor behaviors emphasizing the crucial role of video-polysomnography for their differential diagnosis. In these articles, we critically review the major findings and updates on SHE and DOA, offering an overview of new clinical frontiers and promising future research areas.
