The National Institutes of Health (NIH) estimates that there are as many as 200,000 Americans suffering with Narcolepsy, but only about 50,000 are diagnosed with the disorder. In the UK, the figures are similar in relation to the general population. There are approximately 2,000 diagnosed Narcoleptics, yet it is believed that there are as many as 20,000.

The disorder is often mistaken for depression, simple lack of sleep, bad time management/keeping late hours, or other conditions that cause abnormal sleep patterns.

The first symptoms usually appear in the teens and early twenties, but an average of fifteen years passes before most people are formally diagnosed.

EFFECT OF NARCOLEPSY ON DAY TO DAY LIVING

People with Narcolepsy often experience serious problems in their professional and personal lives. Undiagnosed Narcoleptics may be perceived as lazy, lethargic or rude, and their performance may suffer at school or work. Intimate relationships are often affected. Extreme sleepiness may cause low sex drive or impotence and people with Narcolepsy may even fall asleep while making love.

The problems caused by sexual dysfunction may be further complicated by emotional difficulties. Intense feelings, such as anger or joy can trigger some symptoms of Narcolepsy (Cataplectic attacks) causing affected people to withdraw from emotional interactions.

Sleep attacks also frequently result in physical harm to people with Narcolepsy. Affected people whose symptoms aren't managed may be at increased risk of car accidents, burns and cuts if they fall asleep while driving, smoking or preparing food.
