📖What is Narcolepsy?
Narcolepsy is a chronic neurological disorder that affects the brain's ability to regulate normal sleep-wake cycles, causing overwhelming and often uncontrollable episodes of daytime sleepiness. Individuals with narcolepsy may suddenly fall asleep during activities such as talking, eating, or driving, regardless of how much sleep they got the previous night. Many cases also involve cataplexy, a sudden loss of muscle tone triggered by strong emotions like laughter or surprise. The condition results from a deficiency of a brain chemical that regulates wakefulness and typically emerges in adolescence or young adulthood.
