Narcolepsy is best described as a disorder related to what?

Narcolepsy is a neurological disorder that primarily affects the regulation of sleep-wake cycles, which leads to persistent sleepiness throughout the day and sudden sleep attacks. Individuals with narcolepsy often experience overwhelming drowsiness, making it challenging to stay awake for extended periods. These sudden sleep attacks can occur at any time, even during activities such as talking or eating, and are often accompanied by a loss of muscle tone (cataplexy) triggered by strong emotions. This characteristic of uncontrolled sleepiness and the occurrence of unexpected sleep episodes distinctly define narcolepsy, setting it apart from other disorders related to mood, anxiety, or behavior.
