People suffering from narcolepsy experience excessive daytime sleepiness despite a good night’s sleep. The body’s system for staying awake can shut down, triggering a “sleep attack.” In other words, you could fall into a deep sleep at any time.

Causes of Narcolepsy

Narcolepsy is a chronic, neurological sleep disorder that involves the body's central nervous system. Narcolepsy is known to be a genetic disorder, but what causes narcolepsy is not yet known.

Narcolepsy Symptoms

Common symptoms of narcolepsy include:

  • Excessive daytime sleepiness (EDS)
  • Sudden loss of muscle control ranging from slight weakness to total collapse
  • Being unable to talk or move for about one minute when falling asleep or waking up
  • Often experiencing scary dreams and sounds when falling asleep

Diagnosing Narcolepsy

To help diagnose narcolepsy, your physician may recommend laboratory tests to confirm a diagnosis and plan treatment, including:

  • Overnight Polysomnogram (PSG) - to determine the presence of excessive daytime sleepiness (EDS) and perhaps other underlying causes of this symptom.
  • Multiple Sleep Latency Test (MSLT) or MSLT Sleep Study - to measure sleep onset and how quickly rapid eye movement (REM) sleep occurs.

Narcolepsy Treatments

Treatment for narcolepsy may include medications, nap therapy and diet and exercise changes.
