Adult NREM parasomnias present highly variable clinical forms and often cause injuries. Identifying typical phenotypes may help in the risk management of sleep behaviors that characterize parasomnias in different age and sex groups. This research has three parts. First, a cross-sectional representative population survey in Hungary was conducted on the frequency of NREM parasomnias and their types, DOAs’ family accumulation, association with adverse childhood experiences (ACEs), and related risks. Secondly, a YouTube video-based study on sleep-related behaviors likely representing NREM parasomnias to find phenotypes in different age and sex groups. The last study was a retrospective clinical evaluation.
One of the most important findings was the association between NREM parasomnias and ACEs. The prevalence of NREM parasomnias in Hungary was 2.7%, including 0.1% of SRED, approaching the prevalence of anorexia nervosa. SRED was reported by 3.7% of DOA persons. The high (5.5%) occurrence of sexsomnia among sleep-clinic patients calls attention to this intriguing, dangerous, and frustrating condition with potential forensic implications. Currently, there are no large randomized controlled trials for managing NREM parasomnias. Any future studies should consider predisposing, priming, and precipitating factors to find effective treatments for preventing the episodes.
In summary, this thesis provides novel insights into the prevalence, phenomenology, promoters, family accumulation, and risks of injury of adult NREM parasomnias.
