-Narcolepsy affects one in 2,000 Americans in the United States.
-Narcolepsy is typically characterized by the following four symptoms with varying frequencies: Excessive daytime sleepiness, Cataplexy (sudden and temporary loss of muscle tone often triggered by emotions such as laughter), Hallucinations. and Sleep paralysis (paralysis that occurs most often upon falling asleep or waking up; the person is unable to move for a few minutes).
