Question

Quizplus · Accepted Answer

Narcolepsy is often associated with a loss of orexin (also known as hypocretin)-containing neurons in the hypothalamus. Orexin is a neuropeptide that plays a crucial role in regulating wakefulness and arousal. The loss of orexin-producing neurons has been linked to the symptoms of narcolepsy, such as excessive daytime sleepiness and cataplexy.
