One such concern is that slow wave sleep parasomnias may be considered ‘not legally insane’ by medical sleep experts which may be contrary to the relevant law in the jurisdiction. Nocturnal dissociative behaviour, by contrast, clearly involves mental health issues. There are implications for the criminal justice system when the disorders that cause complex nocturnal behaviour entail a continuing risk of harm to others. This means that the insanity verdict or equivalent may be appropriate to ensure supervision and restrictions to protect the public.

While acute intracranial abnormalities on CT were not reliable predictors of self-reported symptoms of insomnia, measures of axonal integrity on diffusion tensor imaging (DTI), particularly involving cortico-subcortical white matter tracts such as the uncinate fasciculus, were highly associated with self-reported sleep disturbance. Individuals with TBI were also found to have decreased delta power and increased beta power on qEEG during sleep, providing preliminary support for the functional role of the hypothalamus in the pathogenesis of post-TBI sleep disturbance. Key study limitations include small sample sizes and heterogeneity of TBI severity and chronicity.
