Narcolepsy is a rare condition. However, if you’re having sleep attacks, it’s important to see a specialist.

Narcolepsy is very uncommon, with only 1 in 2,000 people being diagnosed with the condition. The most common sign of narcolepsy is sleep attacks during the day, also known as excessive daytime sleepiness. During these attacks, a person feels an excessive urge to fall asleep and may do so in the middle of an activity.

It’s also common to experience cataplexy, a sudden but temporary loss of muscle tone, which includes a partial or full body collapse. However, only people diagnosed with type 1 narcolepsy have symptoms of cataplexy.

If you think you have narcolepsy, it’s important you see a specialist who can administer an official narcolepsy test, which consists of polysomnography and the multiple sleep latency test (MSLT).
