What is Narcolepsy?

Narcolepsy is a chronic sleep disorder caused by damage to nerve cells in the brain that produce hypocretin (orexin). Excessive daytime sleepiness and sudden sleep attacks are the main symptoms. Type 1 narcolepsy is accompanied by cataplexy (sudden muscle weakness during strong emotion).

Narcolepsy is associated with an autoimmune mechanism in which the immune system attacks hypocretin-producing neurons. The reporting of some cases after H1N1 vaccination has provided evidence in favor of this mechanism.

Narcolepsy is not life-threatening; however, it can have serious negative impacts on driving, work safety and social life. With appropriate treatment and lifestyle adjustments, symptoms can be significantly controlled.

Symptoms

Persistent excessive daytime sleepiness
Sudden and uncontrollable sleep attacks
Cataplexy: sudden muscle weakness during emotion such as laughter or surprise
Sleep paralysis: brief inability to move while waking up or falling asleep
Hypnagogic hallucinations: vivid, frightening images during sleep onset
Fragmented night sleep and frequent awakenings

Risk Factors

Family history of narcolepsy
Carrying HLA-DQB1*06:02 allele
Autoimmune predisposition
Streptococcal infection or H1N1 virus exposure
Head trauma or brain tumor (secondary narcolepsy)

If you experience any of the following symptoms, seek medical attention promptly:

  • If you have sudden daytime sleep attacks and cannot prevent them
  • If sudden tightening or falling occurs during emotion
