Narcolepsy意思

Narcolepsy is a neurological disorder that affects the brain's ability to regulate sleep-wake cycles. People with narcolepsy experience excessive daytime sleepiness and may suddenly feel very sleepy at inappropriate times, such as while talking, eating, or driving. Other symptoms can include cataplexy (sudden loss of muscle tone), sleep paralysis (inability to move for a short time when waking up or going to sleep), and hypnagogic hallucinations (vivid dreams or visions while falling asleep). The exact cause of narcolepsy is not fully understood, but it is believed to be related to a lack of the brain chemical hypocretin, which helps regulate sleep and wakefulness. Treatment for narcolepsy typically includes lifestyle changes, such as maintaining a regular sleep schedule, and may also involve medication to help control symptoms.
