What is Narcolepsy?
Narcolepsy is a neurological disorder characterized by extreme daytime sleepiness and uncontrollable episodes of falling asleep during the day. This excessive daytime sleepiness should not be mistaken for the afternoon slump, since neurological defects are responsible for narcolepsy, rather than just sleep deprivation or lack of caffeine!
How Common is Narcolepsy?
Between 1 in 2000 and 1 in 5000 people are affected by narcolepsy. However, only about 25% of the cases are correctly diagnosed, and often narcoleptics are mistakenly diagnosed with psychiatric or emotional problems. Family members of an affected individual also have a 20X – 40X increased risk of developing narcolepsy.
This genetic analysis detects the HLA-DQB1*06:02 allele associated with narcolepsy. It is a useful tool, in conjunction with other clinical symptoms, for an accurate narcolepsy diagnosis.
