A neurological condition called narcolepsy interferes with the brain's capacity to control sleep-wake cycles. Even after a full night's sleep, it results in unexpected, uncontrolled periods of daytime slumber. Bypassing the typical phases of sleep, the brain may enter REM sleep nearly immediately. This results in symptoms including sleep paralysis, cataplexy (sudden muscular weakness), and excessive daytime drowsiness. Artvigil 150, which contains the wakefulness-promoting drug armodafinil, is one possible therapy. By boosting dopamine and other neurotransmitters, Artvigil 150 helps fight drowsiness.
