Abstract

Assessment of sleep patterns in blind people demonstrates a high prevalence of sleep disorders. Our studies have shown that subjects with no conscious light perception (NPL) have a higher occurrence and more severe sleep disorders than those with some degree of light perception (LP). A detailed study of 49 blind individuals showed that those with NPL are likely to have free-running (FR) circadian rhythms (aMT6s, cortisol) including sleep. Non�24-hour (or FR) sleep-wake disorder, characterised by periods of good and bad sleep is a condition that may benefit from melatonin treatment. Melatonin has been administered to NPL subjects with FR circadian rhythms and compared with placebo (or the no-treatment baseline) sleep parameters improved. The results suggest that prior knowledge of the subject�s type of circadian rhythm, and timing of treatment in relation to the individual�s circadian phase, may improve the efficacy of melatonin. © 1999 S.
