Sleep Disturbances in Children and Adolescents With Post-traumatic Stress Disorder (PTSD): a Randomized Double-blind Placebo-controlled Trial to Investigate the Efficacy of Pediatric Prolonged-release Melatonin

Обзор

Among the most sensitive and persistent symptoms of post-traumatic stress disorder (PTSD) in children are sleep disturbances in the insomnia spectrum (sleep onset disturbances, fragmented sleep with multiple nocturnal awakening, early morning awakening) as well as nightmares, affecting over 50% of children and adolescents one year after the initial trauma. There are currently no gold standard treatments or pharmacological treatment recommendations specifically for these sleep disturbances in children and adolescents with PTSD, despite the fact that they have a significant effect on daytime functioning and overall mental health of the children and their families. If not treated appropriately, these sleep disturbances in children and adolescents persist over time, and further increase anxiety in children. Sleep disturbances associated with PTSD are predictive of the persistence and long-term outcome of PTSD itself and associated depressive symptomatology, and of a decreased response rate to cognitive-behavioral psychotherapy for PTSD. We have previously shown in an international multicenter study that pediatric prolonged release melatonin (PedPRM) has high beneficial effects on sleep disturbances of the insomnia spectrum in children ages 2-17.5 years with autism spectrum disorder, and consecutive positive effects on children's daytime behavior, including anxiety and depressive symptomatology. Its benefit-risk ratio has proven to be excellent over a 2-year follow-up. Beyond its therapeutic benefit on mental health through improvement of sleep, melatonin may have a direct effect on reducing anxiety levels and overall daytime functioning in children, as well as sleep and daytime function in caregivers. Our study will be the first randomized controlled trial investigating the efficacy of prolonged release melatonin on sleep disturbances in children and adolescents with PTSD, as well as on PTSD symptoms, associated daytime function and overall mental health in these children and their caregivers.
