According to the third edition of the International Classification of Sleep Disorders (ICSD-3), sleep parasomnias involve episodes of unusual vocal and motor behaviors and sensory or emotional perceptions during sleep. These occurrences are concomitant to specific sleep stages or appear during transition periods between sleep and wake and are associated with dream mentation. Parasomnias can be classified into rapid-eye movement (REM) related (eg, nightmare disorder, recurrent isolated sleep paralysis, REM sleep behavior disorder, sleep-related hallucinations) and non–rapid eye movement (NREM) related (eg, confusional arousals, sleep-related eating disorder, sleep terrors, sleep walking). Healthcare providers should be aware of several less frequently diagnosed parasomnias that could affect the sleep of patients across specialties. Estimated incidence and prevalence of these behaviors vary widely depending on the specific behavior and need to address the parasomnia in question.
