Parasomnias are behavioral or experiential events that occur only during sleep or at the waking up period. Furthermore, some are even sleep-stage specific, occurring only during specific stages of sleep. Disorders of arousal (sleepwalking, sleep terrors, and confusional arousals) and sleep-related eating disorder are non-REM parasomnias. Simple reassurance and sleep hygiene is enough treatment in the majority of cases. Pharmacologic treatment is indicated in disorders of arousal associated with either vigorous behavior or injury, or else with extremely frequent episodes. In such instances, benzodiazepines, in particular clonazepam, are highly effective. Idiopathic cases of sleep-related eating disorder may respond to topiramate.
