Abstract
The frequency and type of sleep disorders in 77 blind children, from 3 to 18 years of age, were compared with 79 matched controls, using a 42-item questionnaire in a study at the Stanford University Sleep Disorders Center, Stanford, CA, and the Laboratoire du Sommeil, Centre Hospitalier Universitaire de l’Hotel-Dieu a Paris, France.
Highlights
Mean total sleep time was similar in both groups; it was 526+/-61 minutes on weekdays and 600 min on weekends
Children with ADHD, in comparison with normal children, experience more sleep problems evidenced by dyssomnias and involuntary movements, but the frequency of parasomnias is similar to that in normally developing peers
A significantly greater proportion of blind children (17%) slept less than 7 hours per night on weekdays compared to controls (2.6%), and blind subjects had more sleep complaints
Summary
Mean total sleep time was similar in both groups; it was 526+/-61 minutes on weekdays and 600 min on weekends. Children with ADHD, in comparison with normal children, experience more sleep problems evidenced by dyssomnias and involuntary movements, but the frequency of parasomnias is similar to that in normally developing peers. Except for the association of sleep-related involuntary movements and the combined subtvpe of ADHD, sleep problems in ADHD children do not differ from those in clinicai comparison groups without ADHD.
