Living with Narcolepsy

A long-lasting sleep condition with strong daytime sleepiness and sometimes sudden loss of muscle tone.

Understanding Narcolepsy

Narcolepsy is a chronic sleep condition that disrupts the normal sleep-wake cycle.

It can appear at any age but most often begins in adolescence. People feel tired during the day and may feel an overwhelming urge to sleep several times a day. These sleep attacks last seconds to minutes, and people often wake feeling refreshed. Many also have cataplexy, a sudden loss of muscle tone triggered by strong emotion. Nighttime sleep is also affected.

Signs & symptoms

GARD doesn't list a detailed symptom list, but the summary describes these features:

  • Strong daytime sleepiness
  • Sudden sleep attacks
  • Sudden loss of muscle tone with strong emotion (cataplexy)
  • Trouble sleeping through the night
  • Vivid dream-like images while falling asleep or waking
  • Short periods of being unable to move or speak (sleep paralysis)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
