Nicole Delien slept 64 days due to Kleine-Levin syndrome
The Pennsylvania teen suffers from a rare sleep disorder called Kleine-Levin, or "Sleeping Beauty Syndrome" -- only an estimated 1,000 people worldwide are afflicted. During her sleep spells -- of which her 64-days stint from Thanksgiving into January was her longest -- Delien will wake in a confused state for short stretches to eat and use the bathroom before falling back asleep.
The disorder otherwise causes her to sleep 18 to 19 hours a day. Per the Daily Mail, the teen's mother, Vicki Delien, says it was frustrating getting a diagnosis for her daughter. Ultimately, a doctor at Allegheny General Hospital in Pittsburgh, Penn., diagnosed the teen and offered suggestions on how to manage the disorder, including medication.
Other symptoms of Kleine-Levin syndrome, which mostly affects young males, include disorientation, hallucination, child-like behavior, binge-eating and periods of hyper-sexuality when awake. The disorder's cause is unknown.
