Narcolepsy

Moderate

Narcolepsy is a chronic neurological disorder that causes excessive daytime sleepiness and an uncontrollable tendency to fall asleep during the day. Some people also experience cataplexy, a sudden temporary loss of muscle control triggered by emotions. Other features may include sleep paralysis, vivid dream-like experiences when falling asleep or waking, and disrupted nighttime sleep.

Overview

Narcolepsy is a chronic neurological disorder that causes excessive daytime sleepiness and an uncontrollable tendency to fall asleep during the day. Some people also experience cataplexy, a sudden temporary loss of muscle control triggered by emotions. Other features may include sleep paralysis, vivid dream-like experiences when falling asleep or waking, and disrupted nighttime sleep.

Symptoms 2

Fainting Increased Urination

Causes 1

Narcolepsy is associated with abnormalities in the brain systems that regulate sleep and wakefulness. Narcolepsy with cataplexy is commonly linked to a major loss of neurons that produce hypocretin, also called orexin, a chemical involved in maintaining wakefulness. Genetic susceptibility and immune-system factors may contribute. In some cases, narcolepsy can occur after certain brain injuries or other neurological conditions.
Genetics

Risk Factors

Risk may be influenced by family history and genetic susceptibility. Having a close relative with narcolepsy may increase the likelihood of developing the disorder, although most people with narcolepsy do not have an affected close family member. Certain neurological injuries or diseases may also be associated with secondary forms of narcolepsy. The condition can begin at different ages but often starts during adolescence or young adulthood.

Diagnosis

Diagnosis is based on a patient's medical history, symptoms, physical examination and, when necessary, laboratory or imaging investigations.
Diagnosis requires assessment of daytime sleepiness, nighttime sleep patterns, cataplexy and other symptoms. A healthcare professional may use sleep diaries and standardized sleepiness questionnaires. Overnight polysomnography can evaluate nighttime sleep and exclude other sleep disorders. A multiple sleep latency test performed during the following day can measure how quickly a person falls asleep and whether REM sleep occurs unusually early. Hypocretin testing may be considered in selected cases.

Prevention

Key Prevention Tips
There is no established way to prevent most cases of narcolepsy because its underlying causes are not fully understood
Recognizing persistent excessive daytime sleepiness and seeking evaluation can help identify the disorder and reduce associated problems
People with narcolepsy should follow their treatment plan, maintain regular sleep schedules, use planned naps when advised, and take appropriate precautions around driving, operating machinery, and other activities affected by sudden sleepiness
