Narcolepsy
The five classical signs of narcolepsy are EDS, cataplexy, sleep paralysis, hallucinations, and disrupted sleep.

Narcolepsy is a neurological disorder that affects your ability to sleep and wake up. People with narcolepsy have excessive, uncontrollable daytime sleepiness. They may also suddenly fall asleep at any time, during any type of activity.

About in 1 in 2,000 Americans have some type of narcolepsy.

What are the five signs of narcolepsy?

The five classical signs of narcolepsy are:

  1. Excessive daytime sleepiness (EDS): This can be seen even after getting enough sleep. It is hard to perform any activities.
  2. Cataplexy: This means a sudden loss of muscle tone. This can cause problems such as slurred speech or total body collapse.
  3. Sleep paralysis: It is the inability to move upon awakening. Sleep paralysis last for few seconds to several minutes
  4. Hallucinations: They can occur either during sleep onset (hypnagogic) or during awakening (hypnopompic).
  5. Disrupted sleep: Sleep may be disturbed at night due to vivid dreams, breathing problems or body movements

What are the narcolepsy-related conditions?

  • Polysomnogram is a sleep study that requires you to stay at a sleep center overnight.
  • Multiple sleep latency tests (MSLT) measures your day time sleepiness.
