Narcolepsy Overview

Epidemiology: Narcolepsy

There are approximately 200,000 Americans who suffer from narcolepsy. This means that roughly 1 in 2000 people have narcolepsy. Some studies suggest that of the 200,000 people who are diagnosed with narcolepsy, up to 150,000 people go undiagnosed. There are several factors that have been identified which may increase the risk of developing narcolepsy. These include other family members who have been diagnosed with narcolepsy, certain thyroid disorders, diabetes, and autoimmune disorders. An autoimmune disorder is a disease in which the body's immune system mistakenly attacks the body's own organs and tissues.

Prevalence Related to Ethnicity

There are no strong statistics which indicate one ethnicity is at higher risk of developing narcolepsy than any other. Narcolepsy has been shown to occur in any person of any race.

Prevalence Related to Gender

As of now, there are no strong statistics which indicate that one the risk of developing narcolepsy is higher in males or females.

Prevalence Related to Age

Narcolepsy has been shown to occur in people at nearly every age. However, some studies show narcolepsy occurs more frequently in certain age groups than others. The chances of developing narcolepsy before the age of five is extremely rare. Narcolepsy occurs most commonly in people between the ages of 15 and 30. Because narcolepsy can appear suddenly or gradually, some people will show mild symptoms for a few years before developing full blown narcolepsy.
