People who are totally blind are prone to a cyclic form of insomnia, designated in medical terminology as non-24-hour sleep-wake syndrome. It is caused by a lack of synchrony between the internal body clock and the daily sloop-wake schedule. This article describes the clinical features and biological basis of the disorder and discusses the implications for its management and treatment.
