Sleep Disorders, Sleep Medication Use, and Predictors of Sleep Disturbance in Children with Persistent Tic Disorders.

Overview

The present study examined rates of sleep disorders and sleep medication use, and predictors of sleep disturbance in children with persistent tic disorders (PTD). Sixty-three parents of children aged 10 to 17 years with PTDs completed an internet survey evaluating sleep patterns and clinical symptoms. Insomnia (19.4%), nightmares (16.1%), and bruxism (13.1%) were the most commonly reported lifetime sleep disorders. Fifty-two percent endorsed current sleep medication use. Higher ADHD severity, overall life impairment, and female sex predicted greater sleep disturbance. Findings suggest the utility of clinical management of co-occurring ADHD and impairment to mitigate sleep disturbance in children with PTDs.
