Non-24-hour Sleep-Wake Rhythm Disorder.
Study Goal
The researchers aimed to evaluate the role of melatonin in treating Non-24-hour sleep-wake rhythm disorder, particularly in blind and sighted individuals.
Results Summary
Melatonin was found effective in treating Non-24-hour sleep-wake rhythm disorder in blind individuals, while sighted individuals required additional time cues like light, social interactions, and activity for effective treatment.
Population
Blind individuals without light perception and sighted individuals with Non-24-hour sleep-wake rhythm disorder.

Non-24-hour sleep-wake rhythm disorder is a circadian rhythm sleep-wake disorder characterized by an inability to entrain to the 24-hour environment. Patients present with complaints of insomnia or hypersomnia, with progressive daily shifts of sleep-wake activity on actigraphy or sleep logs. Although first recognized in blind individuals without light perception, it also can be seen in individuals with intact vision. Treatment focuses on timed melatonin in blind individuals, whereas it is more complex in sighted individuals, using multiple time cues, such as light, melatonin, social interactions, feeding, and activity.
