What does the DSM-IV define as     A. The predominant complaint is excessive sleepiness for at least 1 month (or less if recurrent) as evidenced by either prolonged sleep episodes or daytime sleep episodes that occur almost daily. B. The excessive sleepiness causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.     C. The excessive sleepiness is not better accounted for by Insomnia and does not occur exclusively during the course of another Sleep Disorder (e.g., Narcolepsy, Breathing-Related Sleep Disorder, Circadian Rhythm Sleep Disorder, or a Parasomnia) and cannot be accounted for by an inadequate amount of sleep. D. The disturbance does not occur exclusively during the course of another mental disorder. E. The disturbance is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition.
Excessive daytime sleepiness Excessive daytime sleepiness Excessive daytime sleepiness (EDS) is characterized by persistent sleepiness and often a general lack of energy, even during the day after apparently adequate or even prolonged nighttime sleep. EDS can be considered as a broad condition encompassing several sleep disorders where increased sleep is a symptom, or as a symptom of another underlying disorder like narcolepsy, idiopathic hypersomnia, sleep apnea or a circadian rhythm sleep disorder. Some persons with EDS, including those with hypersomnias like narcolepsy and idiopathic hypersomnia, are compelled to nap repeatedly during the day; fighting off increasingly strong urges to sleep during inappropriate times
Caffeine-induced sleep disorder medication containing caffeine and difficulty in falling asleep. 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, a circadian rhythm sleep disorder or a mental disorder, then caffeine-induced sleep disorder is not the cause. This condition causes a notable impairment in functioning in sufferers. Overconsumption: Although the maximum daily consumption
