Living with Sleeping Beauty Syndrome

Can you imagine sleeping through your birthday? Or Christmas?

Although it shares its name with a beloved princess, Sleeping Beauty Syndrome is nothing to dream about. Officially known as Kleine-Levin Syndrome, this rare neurological disorder results in episodes where patients sleep for 17-20 hours a day, for weeks at a time. The time spent awake isn't productive, because the patient is often in a sleepwalking-like state and has regressed to childlike behavior, and, at the conclusion of the episode, has no recollection that anything abnormal has happened.

In this clip from The Jeff Probst Show, Probst interviews Nicole Delian, a young woman with Sleeping Beauty Syndrome, who shares, along with her parents, the toll this condition takes on their family. This episode was aired last year.

In a report, Yahoo! 7 News correspondent Rahni Adler points out: "Doctors know little about KLS, but believe it could be triggered by something as simple as the common cold. It’s believed to have something to do with the hypothalamus, the part of the brain that controls the sleep, wake and hunger cycles. It usually strikes victims in their teens and can last for more than a decade."

In this clip from Australia's Sunday Night News, teens Alana Wong and Analeigh Bradbury talk about their experience with KLS.
