How rare is KLS?
KLS is very rare, occurring at a rate of 1 in 1 million, which limits research into genetic factors. The condition primarily affects adolescent males, though females can also be affected and the age of onset varies.
What is the rarest sleep disorder?
Kleine-Levin Syndrome (KLS), also known as “Sleeping Beauty” syndrome, is a rare neurological disorder characterised by recurrent bouts of hypersomnolence (excessive sleeping) along with cognitive and behavioural problems during wakefulness.
Is KLS hereditary?
The exact cause of Kleine-Levin syndrome is not known. However, researchers believe that in some cases, hereditary factors may cause some individuals to have a genetic predisposition to developing the disorder.
How long does Kleine-Levin syndrome last?
It is characterized by recurring but reversible periods of excessive sleep (up to 20 hours per day). Symptoms occur as “episodes,” typically lasting a few days to a few weeks. Episode onset is often abrupt, and may be associated with flu-like symptoms.

Can Kleine Levin be cured?
Treating Kleine-Levin Syndrome There is no specific, definitive treatment to cure or control KLS. Some aspects of the disease can be managed with medication, such as stimulants to combat the EDS, but this is most effective only once the episodes have already decreased in severity.
What is fatal familial insomnia?

How many people have Kleine Levin?
It affects around 1/500 000 individuals. Patients are mostly male (68-78% of cases) and adolescents (81% of patients), with a mean age of onset of 15 years (range 4-82 years).
Can you survive FFI?
FFI is usually fatal in 6-36 months. Almost all cases of FFI occur due to a specific variant in the PRNP gene and are inherited in an autosomal dominant pattern. Diagnosis is based on the symptoms, clinical exam, sleep study, and imaging studies. The results of genetic testing can help confirm the diagnosis.
