The Sleep Disorder Center of Sacre-Coeur Hospital of Quebec carried out a research study on twins considering the growing evidence of genetic factors as involved in the sleep terror disorder occurrence. The twin studies they conducted will provide the vital factors played by genetics and environment affecting the manifestation of the disorder. They assessed the frequency and prevalence of sleep terror at 18 to 30 months of age with administered questionnaires to the twin’s biological mother. The result of the study showed that sleep terror occur at 36.9% at 18 months and 19.7% by the age of 30 months. Boys are affected by 49% while girls at 51%. The sleep terror disorder was explained by the 2-component model at 18 months showing 43.7% additive genetics ans 56.3% non-shared environment. By 30 months there are 41.5% additive genetic effects and 58.5% non-shared environment. The conclusion of the study showed strong support to the role of hereditary factor in sleep terror disorder. It also proposes the continuity of genetic effects with the persistence of symptoms of sleep terror disorder. 9


A study conducted by the Sleep Medicine Services of the Lankeau Hospital was carried out to review the medical and legal case reports to determine how many appear to support the belief that there is occurrence of violence during the disorders of confusional arousal, sleepwalking, and sleep terrors which does not occur randomly or spontaneously, but is actually triggered by physical contact or close proximity to that individual. The study showed that violent behavior associated with provocation or close proximity is present 100% in confusional arousal patients, 81% present in sleep terror patients and 40% - 90% in sleepwalking cases. The provocation is usually minor but the response is highly exaggerated. The conclusion of the research showed that the violent behavior directed against others associated with a disorder of arousal is due to direct provocation to another individual. Sleepwalkers usually do not seek out victims but their victims encountered the sleepwalker. Furthermore the pathophysiology of disorder of arousal with or without the violent behavior is associated with normal occurring deactivation of the frontal lobes during the slow wave sleep that is connected through the active thalamocortical pathways to the limbic area. And there is no evidence to cite whether the violent sleepwalker, sleep terror patient or confusional arousal patient differs from other persons with these disorders and there is needed more sleep laboratory based studies to confirm it. 10
