A British teen suffering from a rare neurological disorder that induces long periods of sleep recently awoke after sleeping for two months.
"I've missed nine exams and my birthday in November," 15-year-old Stacey Comerford tells the Sun. "It's easier now people know what it is. It's easier to explain to them. Before, people didn't believe me. That was the hardest thing."
Comerford suffers from Kleine Levin Syndrome (KLS), also known as Sleeping Beauty Syndrome, a condition affecting only about 1,000 people around the world.
The National Institute of Neurological Disorders and Stroke (NINDS) says Kleine Levin Syndrome affects primarily adolescent males (70 percent) and can often result in an individual sleeping for up to 20 hours at a time. While there is no treatment or cure for the condition, many individuals living with the condition simply outgrow it as they age, usually over the course of 8 to 12 years.
The NINDS describes the symptoms as, "Episode onset is often abrupt, and may be associated with flu-like symptoms. Excessive food intake, irritability, childishness, disorientation, hallucinations, and an abnormally uninhibited sex drive may be observed during episodes."
"There's never any warning. I've even found her fast asleep on the kitchen floor," Comerford's mother, Bernie Richards, tells the Sun. "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."
Richards says doctors initially waved off her daughter's symptoms as a result of "moody" behavior.
