Question

true or false: narcolepsy occurs due to a disruption of only the ascending arousal system?

Explanation:

Narcolepsy is a complex disorder. While the ascending arousal system is involved, it is not the only factor. There are also issues related to the hypocretin (orexin) system in the brain. Hypocretin is important for regulating wakefulness and sleep - wake transitions. A deficiency in hypocretin neurons (which can be due to genetic and autoimmune factors) is a key aspect of narcolepsy. So, it is not just a disruption of the ascending arousal system.

Answer:

False
