Narcolepsy is a nervous system disorder.

In most patients, Narcolepsy is linked to low amounts of a protein called Hypocretin which is made in the brain. What causes the brain to produce reduced amounts of this protein is unknown. Sometimes, the body’s immune system mistakenly attacks the brain cells involved in regulating the sleep-wake cycle. It is believed that narcolepsy is the result of these cells being damaged or destroyed.
