Quizplus · Accepted Answer

Individuals with narcolepsy have a reduced number of nerve cells in the brain that produce hypocretin (also known as orexin), a neurotransmitter that regulates wakefulness and alertness. The lack of hypocretin is believed to be responsible for the symptoms of narcolepsy, including excessive daytime sleepiness and sudden episodes of falling asleep.
