(ST. LOUIS, Mo.) - New research may have discovered a link between sleepwalking and a person's genetic makeup, reports the BBC.
The study, published in the the journal Neurology, found that the sleep episode may be caused by a defect in a person's DNA carried on a section of the chromosome 20. The faulty chromosome can be passed down from generation to generation with a sleepwalker having a 50-percent chance of passing the DNA onto their children.
Researchers at Washington University School of Medicine hope the discovery could help them understand and treat the potentially dangerous condition.
Sleepwalking, which is most common in children, is a phenomenon that occurs during a deep phase of sleep where a person can sometimes perform extremely complicated tasks in a trance-like state. The condition affects around one in 50 adults.
