Abstract
-
Three studies of elderly insomnia are presented. In Experiment 1 the effects of bright and dim light on body core temperature, nocturnal sleep and daytime alertness were investigated in sixteen elderly subjects. Subjects exposed to bright light evidence a shift in the body temperature rhythm and an increase in several important measures of sleep quality. Performance and alertness was not significantly effected. In Experiment 2 the relationship between nocturnal sleep variables and sleep tendency was examined in forty-three elderly insomniacs. The results indicated that in this population associations between nocturnal sleep and daytime sleep tendency remain obscured under basal conditions. In Experiment 3 the relationship between daytime alertness and nocturnal sleep variables was examined in the sixteen subjects from Experiment 1. In addition, a post-hoc analysis was carried out between a sub-set of subjects from Experiment 2 who were administered the multiple sleep latency test, and the subjects in Experiment 1 who were administered the repeated test of sustained wakefulness. The repeated test of sustained wakefulness was inversely associated with nocturnal sleep fragmentation, while no significant differences were observed between the two tests when group mean sleep latencies were calculated.
