The effects of cocaine on mood and sleep in cocaine-dependent males.
The effects of cocaine use and withdrawal on mood and sleep were examined. Three cocaine-dependent men lived in an inpatient facility for approximately 4 weeks, which included an initial abstinence phase (8-10 days), a cocaine administration phase (5 days), and a 2nd abstinence phase (14-16 days). During the 2nd phase, cocaine was administered intranasally a few hours before bedtime. During the day, mood and daytime sleepiness were measured, and sleep was monitored each night. Cocaine produced typical changes in mood and blood pressure, and sleep was severely disrupted. Following Phase 2, there were no changes in mood that was indicative of an abstinence syndrome, although, initially, daytime sleepiness increased. After 2 weeks, sleep architecture remained different from age-matched controls. This study is the first to measure changes in sleep architecture polysomnographically following a period of controlled cocaine use.
