Causes of NarcolepsyHypocretin, also called orexin, is a peptide promotes wakefulness, inhibits REM sleep, and associates with motor control
Narcoleptics generally do not have as many neurons that secrete hypocretin, which inhibits the ability to fully control alertness and accounts for tendency to fall asleep
