Narcolepsy affects both men and women and symptoms often start in childhood or adolescence, but can occur later in life. The condition is life-long.
Narcolepsy is not rare, but it is an under-recognised and under-diagnosed condition.
Some well-known personalities who suffered from the condition include:
1. The late British prime minister Winston Churchill.
2. Comedian Jimmy Kimmel: makes light of his narcolepsy by saying, "Truth be told, I'd rather have narcolepsy than not have it. When I get on a flight to Vegas, I'll fall asleep before the plane takes off and wake up after it has landed. I'm always very close to sleep."
3. Actress Nastassja Kinski: suffers from disorder and frequently discusses her condition publicly.
4. Nirvana frontman Kurt Cobain was undiagnosed as a narcoleptic, but he claimed that he suffered from the condition in interviews.
