British teen can sleep for months at a stretch

A school girl from Britain suffers from Kleine Levin syndrome which means she can sleep for months at a time.

The condition, also known as Sleeping Beauty syndrome, is so rare there are only around 1,000 sufferers in the world.
Yet Stacey Comerford of Telford, Shrops, is not the only British teenager hit by it as Mitchell Baldwin, 14, of Arbourthorne, Sheffield, can sleep for 22 hours a day, only waking to eat in a trance-like state.
Baldwin, who has missed exams and slept through holidays, finds the whole experience frustrating. “It’s frustrating. Life is passing me by,” the Mirror quoted him as saying.
Comerford’s mother Bernie Richards revealed that her daughter’s attacks could come on at any time. The longest lasted two months. “There’s never any warning. I’ve even found her fast asleep on the kitchen floor,” Richards said. “When she’s in an episode, she might get up to go to the toilet or get a drink but she’s not awake. I call it sleep mode.
“When she wakes, she thinks it’s the following day. She doesn’t have any memory of it,” she said.
