Symptoms & Signs
What are the signs and symptoms of the condition?
Narcolepsy has four classic symptoms:
Sometimes a person with narcolepsy will also have symptoms of disturbed nighttime sleep. He or she may toss and turn, jerk about, have nightmares, or wake up a lot. The person may also have automatic behaviors. During the day, he or she may perform familiar and repetitive tasks without being fully aware of them. The person may not remember this behavior afterwards.
The very first symptom to appear is usually the unrelenting, excessive sleepiness during the day. Someone with narcolepsy may have many symptoms or very few symptoms. The development of this disorder and the severity and frequency of the symptoms vary widely.
