Narcolepsy: Symptoms, Causes & Treatment

Narcolepsy is a chronic neurological disorder affecting the brain's ability to regulate sleep-wake cycles normally. The result is severe, irresistible daytime sleepiness, even after adequate night sleep, and the patient may suddenly be overcome by sleep at inappropriate times such as during work, conversation, or even eating.

Narcolepsy occurs due to a disturbance in the brain signals regulating wakefulness, and its most common type is linked to a deficiency of a brain chemical called orexin (hypocretin) responsible for maintaining wakefulness. Among its most distinctive symptoms, in addition to sleepiness, is a state known as cataplexy: a sudden, temporary loss of muscle strength often triggered by strong emotions such as laughter or surprise, in addition to sleep paralysis, hallucinations when falling asleep or waking, and disturbed night sleep.

It is very important to understand that narcolepsy is not laziness or lack of discipline but a real neurological disease that is often diagnosed years late and misunderstood. It affects study, work, driving, and relationships and may put the patient at risk. Although there is no definitive cure yet, symptoms are well manageable with a combination of wakefulness-promoting medications and drugs for cataplexy, and lifestyle changes such as scheduled short naps and regular sleep. Correct diagnosis through a sleep study is an essential step to improving the patient's life.

• Severe irresistible daytime sleepiness and sudden sleep attacks.
• Cataplexy: sudden loss of muscle strength with strong emotions.
• Sleep paralysis (inability to move when falling asleep or waking).
• Hallucinations when falling asleep or waking.
• Disturbed night sleep.

• A disturbance in the brain signals regulating wakefulness.
• A deficiency of orexin (hypocretin) in the most common type.
• Immune, genetic factors, and triggers are thought to play a role.

• Clinical assessment of distinctive symptoms such as sleepiness and cataplexy.
• An overnight sleep study and a daytime multiple sleep latency test.
• Sometimes measuring orexin level or other tests.

Medication

• Wakefulness-promoting stimulants to reduce daytime sleepiness.
• Medications for cataplexy and sleep paralysis by prescription.

Lifestyle changes

• Scheduled short naps during the day.
• Regular night sleep and avoiding caffeine before bed.
• Caution when driving and operating machinery.
