Question

Quizplus · Accepted Answer

Narcolepsy is mainly caused by a deficiency in hypocretin (also known as orexin) receptors in the brain. Hypocretin is a neurotransmitter that helps regulate wakefulness and sleep. A lack of hypocretin leads to excessive daytime sleepiness and can cause other symptoms of narcolepsy, such as cataplexy (sudden loss of muscle control) and hallucinations. Deficiencies in other neurotransmitters, such as dopamine and serotonin, can also cause sleep disorders but are not specifically linked to narcolepsy. Acetylcholine plays a role in REM sleep, but its deficiency is not associated with narcolepsy.
