PURPOSE OF REVIEW: The purpose of this review is to help further the understanding of the clinical profile of patients with sexsomnia and to better understand the spectrum of the clinical manifestations of sexsomnia. We will review the literature from the past decade on the subject and then compare it with our own clinical experience from patients who were retrospectively identified with sexsomnia at a tertiary sleep clinic over a 6-year period. RECENT FINDINGS: The prevalence of sexual behaviours in sleep remains unknown, but it seems to involve predominantly younger male adults who also frequently exhibit other non-rapid eye movement-related parasomnias...

Sleep-related abnormal sexual behaviors (sexsomnia) are classified as a subtype of NREM sleep parasomnias. Sexsomnia has been reported as part of parasomnia overlap disorder (POD) in two other patients. We present the case of a 42-year-old male patient with video-polysomnography (vPSG) documented POD. The patient had sleepwalking, sleep-related eating, confusional arousals, sexsomnia, sleeptalking, and REM sleep behavior disorder (RBD). Confusional arousals and RBD were documented during the vPSG. This case had the added complexity of obstructive sleep apnea (OSA) playing a role in sleepwalking and sleep related eating, with good response to nasal continuous positive airway pressure (nCPAP)...

The topic of sexual assault during sleep is discussed again on the basis of two case reports and several incidents published in the media. The authors support the assumption of Hohner and Püsche1 (2011). There is evidence that it is indeed possible not to wake up during a sexual assault--even without being under the influence of alcohol, illicit drugs or medication--and that a sexual assault during sleep can pass unnoticed. In such cases the outcome of the criminal trial often depends on the careful assessment of the expert, as the faculty of imagination of those passing judgment varies greatly...

"Sleep sex," also known as sexsomnia, is a sleep disorder characterized by sexual behaviors committed while asleep. There has recently been increased interest in sexsomnia due to controversies arising in legal trials that have been widely publicized in the social and public media. This article attempts to marshal the current information about sexsomnia from the forensic literature and provides an overview of sexsomnia including common features, precipitating factors, prevalence rates, diagnostic procedures, and treatment...

BACKGROUND: Arousal disorders may have serious health consequences. OBJECTIVE: To develop a scale assessing the severity of arousal disorders (Paris Arousal Disorders Severity Scale, PADSS). SETTING: University hospital. DESIGN: Controlled study. PARTICIPANTS: Consecutive patients (older than 15 y), with sleepwalking (SW) and/or sleep terrors (ST), subjects with previous SW/ST, normal controls and patients with rapid eye movement sleep behavior disorder...

This review is aimed at summarizing the current state of knowledge regarding parasomnias, which have been implicated in medicolegal cases as well as providing guidance to those working within common-law jurisdictions regarding the technical aspects of the law. Sleepwalking and sexsomnia as a defence are being raised more frequently in criminal cases and there has been public debate on their validity. Unfortunately, expert evidence on forensic sleep disorders continues to be heavily opinion-based with the potential for miscarriages of justice seen in recent highly publicized cases...

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...

Sexsomnia is considered a particular form of parasomnia characterized by atypical sexual behaviour during sleep. Only a few cases have been reported in the literature. We describe here two cases of sexsomnia that took place in adult women whose personal history was remarkable for traumatic sexual psychological stress during childhood. In addition, the first patient had a medical history of alcoholism during adolescence and current sleepwalking. In the second patient, drug consumption was reported during adolescence, and psychiatric assessment found a major depressive disorder...

INTRODUCTION: Automatic, uncontrolled, and unaware sexual behaviors during sleep have occasionally been described. The clinical and polysomnographic features of nocturnal sexual behavior allow it to be considered a distinct parasomnia named "sexsomnia". Recently, abnormal sexual behaviors during sleep have been evaluated in the forensic medical context because violent behaviors can be associated with this parasomnia. AIM: To describe the clinical and polysomnographic findings in three patients who referred to our sleep laboratory for sleep disorders and who reported episodes of sleep-related sexual activation...

Sexsomnia is a parasomnia characterised by sexual behaviour. A 30-year-old man, with no history of parasomnias or related precipitating factors, developed sexual behaviour during sleep after three weeks of treatment with escitalopram 10 mg daily. The parasomnia disappeared on the sixth day after the escitalopram had been stopped. The temporal relationship between the use of this selective serotonin reuptake inhibitor and the occurrence of the parasomnia suggests a causal relationship, possibly related to increased serotonergic neurotransmission in the raphe nucleus...

The objective of the study was to provide further information related to newly described parasomnia variant, Sexual Behaviour in Sleep (SBS, sexsomnia). Previous studies dealt with selected population, typically middle-aged males, featuring extensive medico-legal exposure. At the same time, an anecdotal evidence suggested higher involvement of younger population, and skew towards balance between genders comparable to those seen in other non-Rapid Eye Movement (NREM) sleep parasomnias. The epidemiological information regarding this condition is still virtually non-existent...

This review attempts to assemble the characteristics of a distinct variant of sleepwalking called sexsomnia/sleepsex from the seemingly scarce literature into a coherent theoretical framework. Common features of sexsomnia include sexual arousal with autonomic activation (e.g. nocturnal erection, vaginal lubrication, nocturnal emission, dream orgasms). Somnambulistic sexual behavior and its clinical implications, the role of precipitating factors, diagnostic, treatment, and medico-legal issues are also reviewed...

One major advantage of Web-based research lies in its ability to reach and study people who have rare conditions of interest. Another advantage is that, due to the anonymity of the survey situation, the Internet is particularly suited for surveys on sensitive topics. Sexsomnia is a newly identified medical condition whose sufferers engage in sexual behavior during their sleep. Problematic cases are highly distressing and have forensic implications. The consensus among opinion leaders in sleep medicine is that sexsomnia may be quite common but that it often goes unreported because of shame and embarrassment...

STUDY OBJECTIVES: To formulate the first classification of sleep related disorders and abnormal sexual behaviors and experiences. DESIGN: A computerized literature search was conducted, and other sources, such as textbooks, were searched. RESULTS: Many categories of sleep related disorders were represented in the classification: parasomnias (confusional arousals/sleepwalking, with or without obstructive sleep apnea; REM sleep behavior disorder); sleep related seizures; Kleine-Levin syndrome (KLS); severe chronic insomnia; restless legs syndrome; narcolepsy; sleep exacerbation of persistent sexual arousal syndrome; sleep related painful erections; sleep related dissociative disorders; nocturnal psychotic disorders; miscellaneous states...

Somnambulism or sleepwalking is a viable defence on the basis of automatism. The behaviours that occur during sleepwalking can be highly complex and include sexual behaviour of all types. Somnambulistic sexual behaviour (also called sexsomnia, sleep sex) is considered a variant of sleepwalking disorder as the overwhelming majority of people with Sexsomnia have a history of parasomnia and a family history of sleepwalking. Sexual behaviour during a sleep automatism can vary from explicit sexual vocalisations, to violent masturbation, to complex sexual acts including anal, oral and vaginal penetration...

OBJECTIVE: To describe a distinct parasomnia involving sexual behaviour, which we have named sexsomnia. METHOD: We have used a case series as a basis for the description of sexsomina. RESULTS: Eleven patients with distinct behaviours of the sexual nature during sleep are described. The features in common with other nonrapid eye movement arousal parasomnias, such as sleepwalking are documented. Some patients had simply been referred to a tertiary sleep clinic for investigation of unrelated sleep problems...
