Narcolepsy systems usually first occur during ages 15 to 30.

The most common symptoms are:

  • Periods of extreme drowsiness during the day. You may feel a strong urge to sleep, often followed by a short nap (sleep attack).

    • These periods last for about 15 minutes each, although they can be longer.

    • They may happen after eating, while driving, talking to someone, or during other situations.

    • Most often, you wake up feeling refreshed.

  • Dream-like hallucinations between sleep and wakefulness. They involve seeing or hearing, and possibly other senses.

  • Sleep paralysis. This is when you cannot move as you start falling asleep or when you first wake up. It may last up to 15 minutes.

  • Cataplexy. This is a sudden loss of muscle tone while awake that makes you unable to move. Strong emotions, such as laughter or anger, can trigger this.

      • Most attacks last for less than 30 seconds and can be missed.

      • Your head will suddenly fall forward, your jaw will become slack, and your knees will buckle.

      • In severe cases, a person may fall and stay paralyzed for as long as several minutes.
