Narcolepsy – 2
Narrator: This is NIH Health Matters. I’m Joe Balintfy. Narcolepsy is a rare, chronic disorder of the central nervous system. Only about one in 200-thousand people have it. Those who do, experience irresistible and sudden bouts of sleep. NIH researcher Dr. Giovanni Cizza adds that another symptom of narcolepsy is called cataplexy.
Cizza: Which is when the muscle tone disappears.
Narrator: The loss of muscle tone in cataplexy can be barely noticeable, involving no more than a momentary sense of slight weakness in a limited number of muscles, for example, mild drooping of the eyelids. The most severe attacks result in a complete loss of tone in all voluntary muscles. For more information about narcolepsy and its symptoms, visit www.ninds.nih.gov.
