The DSM-5 refers to narcolepsy without cataplexy as hypersomnolence disorder. Methamphetamine is sometimes prescribed off label for narcolepsy and idiopathic hypersomnia. The diagnosis of narcolepsy and cataplexy is usually made by symptom presentation. Family history is more common in narcolepsy with cataplexy. Adderall is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. Narcolepsy and sleep disorders are common misdiagnoses. It is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity. Methylphenidate is most commonly used to treat ADHD and narcolepsy. Isolated sleep paralysis is commonly seen in patients that have been diagnosed with narcolepsy. Adderall is generally well tolerated and effective in treating the symptoms of ADHD and narcolepsy. Methylphenidate was first used to allay barbiturate-induced coma, narcolepsy and depression. Two trials of GHB for people with narcolepsy demonstrated reductions in sleep paralysis episodes. A second prominent symptom of narcolepsy is abnormal REM sleep. Antidepressants are also used to control some symptoms of narcolepsy. It is approved for the treatment of narcolepsy, ADHD, and exogenous obesity.
