Abstract
INTRODUCTION: The purpose of our study is to describe 4 cases of sexsomnia, a form of parasomnia characterised by sexual behaviour during sleep. METHODS: Clinical history and video-polysomnography recordings from patients diagnosed with sexsomnia in the Multidisciplinary Sleep Unit at Hospital Clínic in Barcelona. RESULTS: Three men and one woman between 28 and 43 years of age reported sexual behaviours during sleep with progression times ranging from 9 months to 7 years. Episodes consisted of masturbation without seeking the participation of a sleeping partner (2 cases) and attempts at sexual intercourse with inappropriate and uncharacteristic vocalizations and behaviours (3 cases). The frequency of the episodes ranged from 4 isolated episodes to 2-3 per week. Patients were amnestic of these events and surprised by their partners' accounts of their behaviour. Medical histories revealed that 1 patient was a somnambulist, 2 had confusional arousals, and 1 experienced somniloquy. Video-polysomnography did not disclose sexual behaviours during sleep but revealed sleep apnoea in 2 cases and periodic leg movements in sleep in another. The only patient treated with clonazepam reported decreased frequency of both confusional arousals and sexsomnia episodes. CONCLUSIONS: Sexsomnia occurs in young adults and is characterised by masturbation and inappropriate attempts at achieving sexual intercourse followed by total amnesia of the events. It can be associated with other parasomnias such as sleepwalking and confusional arousals. Other sleep disorders, including sleep apnoea and periodic leg movement disorder, may trigger episodes of sexsomnia.
