title: [Usefulness of melatonin for developmental sleep and emotional/behavior disorders--studies of melatonin trial on 50 patients with developmental disorders].
abstract: We studied the usefulness of melatonin for sleep disorders and emotional/behavior disturbances of patients with developmental disorders. The efficacy and side effects of melatonin at bedtime were evaluated in 50 children and young adults with sleep disorders (3-28 years old, 41 males and 9 females, autism [AU] in 27 patients, mentally retardation [MR] in 20 patients, and severe motor and intellectual disability [SMID] in 3 patients). The sleep disorders consisted of various types of insomnia in 44 patients and of circadian rhythm sleep disorders in 6 patients. Thirty nine of the insomnia patients and 3 of the circadian rhythm sleep disorder patients experienced improvement in response to melatonin. In some cases, the efficacies were diminished after the daily medication of melatonin. With the emotional/behavior disturbances, excitabilities were often improved in cases whose sleep disorders were also improved. There was almost no change in contrariness, stereotyped behavior and in school/workshop refusal. Melatonin at bedtime was efficacious in 42 of the 50 patients with sleep disorders. In 17 patients, there were side effects (residual drowsiness on the next morning, awakening in the middle of sleep, excitement after awakening and before going to sleep, etc.). But these side effects were not serious. The effects of melatonin were influenced by the type of sleep disturbances, the factors of the environment and the mental conditions. Taking side effects into account, we judged melatonin to be useful in 34 patients.
