Narcolepsy

Narcolepsy is a chronic neurological disorder that affects the brain’s ability to control sleep-wake cycles. People with narcolepsy may experience excessive daytime sleepiness, sudden sleep attacks, and cataplexy (sudden muscle weakness). Treatment often involves medications to manage symptoms, but lifestyle adjustments like regular sleep schedules and planned naps can also be beneficial.
