You are correct! You are incorrect!

It’s a myth that people with narcolepsy spend most of a 24-hour period sleeping. Episodes of sudden bouts of sleep only last from a few seconds to a few minutes, and nighttime sleep is usually poor quality. This disorder blurs the line between sleeping and waking states.

    It’s a myth that people with narcolepsy spend most of a 24-hour period sleeping.

  2. People with narcolepsy also frequently have cataplexy and sleep paralysis

    Correct Answer: True

    Narcolepsy with cataplexy, which is a sudden loss of voluntary muscle tone triggered by strong emotions, affects about one in every 3,000 Americans.  Sleep paralysis is another common symptom.

  3. More men than women get narcolepsy

    Narcolepsy affects both women and men equally, and often starts in childhood or adolescence. Source: [National Institute of Neurological Disorders and Stroke](http://www.ninds.nih.gov/disorders/narcolepsy/detail_narcolepsy.htm)

  4. Most cases of narcolepsy are genetic

    Correct Answer: False

    Actually, most cases are sporadic and occur in people with no known family history of the disorder. However, in some cases there is a familial link. Up to 10 percent of people diagnosed with narcolepsy and cataplexy have a close relative with the same symptoms.

  5. People with narcolepsy frequently experience hallucinations

    Correct Answer: True

    Hallucinations can occur during sleep paralysis, another symptoms of narcolepsy, or when falling asleep or waking up. The images can be very vivid and frightening, and represent another blurring of sleep and wake states, as dreams are typical of REM sleep.

  6. The cause of narcolepsy is not known

    Correct Answer: False

    When cataplexy is also involved, the cause is usually a loss of brain cells that produce hypocretin. Though the cause of the loss isn’t known, scientists believe it’s an autoimmune problem.
