Caffeine-induced sleep disorder

Caffeine-induced sleep disorder is a psychiatric disorder that results from overconsumption of the stimulant caffeine. "When caffeine is consumed immediately before bedtime or continuously throughout the day, sleep onset may be delayed, total sleep time reduced, normal stages of sleep altered, and the quality of sleep decreased."[1]
The specific criteria for this disorder in the fourth version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) include that there must be a significant inability to sleep which is caused entirely by the physiological effects of caffeine as proven by an examination; if sleeping issues can be accounted for due to a breathing-related sleep disorder, narcolepsy, or another mental disorder, then caffeine-induced sleep disorder is not the cause.[citation needed] This condition causes a notable impairment in functioning in sufferers.[2]
