A chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep.
Overview
Narcolepsy is a chronic neurological disorder that affects the brain's ability to control sleep-wake cycles. People with narcolepsy may feel rested after waking, but then feel very sleepy throughout much of the day. Many individuals with narcolepsy also experience uneven and interrupted sleep that can involve waking up frequently during the night.
Symptoms
The primary symptom of narcolepsy is excessive daytime sleepiness (EDS), which can lead to falling asleep in inappropriate situations. Other symptoms include:
- Cataplexy: A sudden loss of muscle tone that can lead to weakness and loss of voluntary muscle control. It is often triggered by strong emotions such as laughter, anger, or surprise.
- Sleep paralysis: A temporary inability to move or speak while falling asleep or upon waking.
- Hallucinations: Vivid and sometimes frightening visual or auditory sensations that occur while falling asleep or waking up.
- Disrupted nighttime sleep: Frequent awakenings during the night.
Causes
The exact cause of narcolepsy is unknown, but it is believed to involve a combination of genetic and environmental factors. In many cases, narcolepsy is associated with low levels of the neurotransmitter hypocretin (also known as orexin), which helps regulate wakefulness and REM sleep.
Diagnosis
Diagnosing narcolepsy typically involves a combination of clinical evaluation and specialized sleep tests. These may include:
- Polysomnography (PSG): An overnight sleep study that records brain waves, heart rate, breathing, and eye movements.
- Multiple Sleep Latency Test (MSLT): Measures how quickly a person falls asleep in a quiet environment during the day.
Treatment
While there is no cure for narcolepsy, symptoms can be managed with a combination of medications and lifestyle changes. Treatment options include:
- Stimulants: Medications such as modafinil and armodafinil are often prescribed to help maintain wakefulness during the day.
- Antidepressants: Certain antidepressants can help reduce cataplexy, sleep paralysis, and hallucinations.
- Sodium oxybate: A medication that can improve nighttime sleep and reduce daytime sleepiness and cataplexy.
- Lifestyle modifications: Scheduled naps, maintaining a regular sleep schedule, and avoiding caffeine or alcohol before bedtime can help manage symptoms.
Living with Narcolepsy
Living with narcolepsy can be challenging, but with proper treatment and support, individuals can lead fulfilling lives. It is important for people with narcolepsy to educate themselves about the disorder and to communicate openly with family, friends, and employers about their condition.
