Narcolepsy
Diagnosis

To diagnose narcolepsy, your doctor will conduct a physical examination and ask about your medical history and symptoms. In addition, a number of tests are available to assist the diagnosis of narcolepsy:

  • PolysomnogramThese tests, performed in an overnight sleep laboratory, measure brain waves and body movements as well as your nerve and muscle function.
  • Multiple Sleep Latency Test (MSLT)This test measures the time it takes you to fall asleep and move into a deep sleep while taking several naps over a period of time.
  • Genetic Blood TestsThese tests check for specific antigens often found in people who have a genetic predisposition to narcolepsy.
