Narcolepsy symptoms occur because the brain is not able to normally control the sleep wake cycles.


Narcolepsy symptoms are characterized by cataplexy (sudden muscle weakness). This can be characterized by a sagging jaw, weakness of the knees, difficulty with speaking, or weakness in the arms and shoulders.


Other symptoms of narcolepsy included hypnagogic (the period between being away and falling asleep) hallucinations.

Narcolepsy symptoms are characterized by episodes of sudden sleep. These sleeping episodes may last seconds to minutes.

The cause of narcolepsy is not known.
