Sleep disturbances in subjects with autism spectrum disorder: A parental perspective.

To investigate the prevalence of sleep disturbances (SDs), their related comorbidities, interventions and the impact on the family for individuals with current SDs and those who had SDs in the past. Members of the Italian national association of parents of persons with autism (ANGSA) completed an anonymous online survey collecting demographic data, the presence of comorbidities and specific information on sleep arrangement and sleep disorders using a modified version of the of the Sleep Disturbance Scale for Children (SDSC). The final sample consisted of 143 participants, 90 patients presented current SDs (C_SDs) and 53 reported previous SDs (P_SDs). In the C_SDs group, the most prevalent sleep disorders were related to insomnia and, especially, difficulty falling asleep; a high number of individuals presented with restless sleep. Also, the parents in the P_SDs group retrospectively reported a high prevalence of insomnia with difficulty falling asleep, night awakenings and restless sleep. Parents reported that sleep hygiene practice were effective in less than one third of cases in both groups and the most used compound was immediate-release melatonin, followed by antihistamines and then benzodiazepines, antipsychotics, and antidepressants, with approximately 60-70% reported efficacy. Parents of both groups reported that insomnia negatively affected their children behavior and caused stress, mood changes or physical fatigue in their daily life. Our study shows that insomnia is most prevalent in individuals with autism with several consequences on children and family behavior and quality of life. As reported by parents, melatonin might be helpful for sleep disturbances in these children and the causes of restless sleep need further investigations.
