Abstract(s)
As parassónias são um grupo que se caracteriza por eventos anormais que ocorrem
durante o sono. Estão classificadas de acordo com a fase do sono em parassónias associadas
ao sono “Non-Rapid Eye Movement” (NREM), associadas ao sono “Rapid Eye Movement”
(REM) e em outras parassónias, quando não enquadradas nas anteriores.
A sexsónia, também apelidada de sonambulismo sexual, é um tipo de parassónia NREM em
que o indivíduo inicia comportamentos sexuais enquanto dorme, sem que se recorde
quando acorda. Os episódios costumam ocorrer nas primeiras horas do sono e podem
repetir-se várias vezes na mesma noite.
A prevalência desta perturbação é ainda desconhecida, mas parece afetar mais os
jovens adultos do sexo masculino e com história prévia de outros tipos de parassónias
relacionadas com o sono NREM.
Apesar de não ser clara a sua etiologia, conhecem-se alguns fatores de risco
associados à má qualidade e fragmentação do sono.
A sexsónia pode ser um problema difícil de gerir, pelas consequências pessoais e
interpessoais, físicas e psicológicas, podendo assumir critérios de disfunção sexual.
Merecem atenção especial as implicações médico-legais desta patologia, em contexto de
casos de comportamento sexual violento e/ou não consentido.
Esta dissertação pretende reunir exaustivamente a evidência atual da investigação
sobre a epidemiologia e a abordagem clínica e psicossocial da sexsónia.
Parasomnias are a group of disorders characterized by abnormal events occurring during sleep. They are classified according to the sleep phase as “Non-Rapid Eye Movement” (NREM) parasomnias, “Rapid Eye Movement” (REM) parasomnias and Other parasomnias, if not fitting the former. Sexsomnia, also known as sexual somnambulism, is a kind of NREM parasomnia in which the subject initiates sexual acts during sleep, with no memory of it when waking up. Such episodes usually happen in the early hours of sleep and may recur several times in the same night. The prevalence of this condition is still unknown, but it seems to affect young adult male with previous history of other NREM parasomnias more often. Despite the unclear aetiology, several risk factors associated with poor quality and fragmentation of sleep were observed. Sexsomnia can be a difficult issue, due to its personal and relational, physical and psychological consequences, or even fulfil criteria for a sexual dysfunction. Forensic implications deserve special concern, in the context of violent and/or non-consented sexual behaviour. This dissertation aims to comprehensively assemble the current research evidence on the epidemiology, clinical and psychosocial management of sexsomnia.
