Genes may be associated with sleep disorder narcolepsy

Monday, January 6, 2014 (HealthDay News)-A new study links genetic mutations to narcolepsy. Narcolepsy is a condition that causes people to become overly sleepy and fall asleep involuntarily.

Narcolepsy is rare, but genetic mutations are fairly common. Of the more than 2,500 participants, researchers found that those with changes were 251 times more likely to suffer from narcolepsy with weakness attacks (weakness caused by behaviors such as laughter) than those without changes. I found that.

For a study published in the journal on January 1st sleepThe researchers analyzed the genetic makeup of about 1,300 people in Europe who suffer from narcolepsy with atonic seizures and more than 1,400 who do not. Almost everyone in this condition had a genetic mutation associated with the functioning of the immune system.

Previous studies have suggested a link between narcolepsy and problems such as infections, according to the American Academy of Sleep Medicine. One theory is that in people who are genetically susceptible to narcolepsy, the immune system breaks out of the bang and accidentally destroys brain cells that are important for alerting the body.

The authors also suggested that high-resolution genotyping, the process of testing an individual’s DNA, may help diagnose patients with suspected narcolepsy.
