About one-third of Americans have sleepwalked in life; Research


Researchers have found that about one in three Americans have walked in sleep during their life.

This research has been published online in the May 15 issue of the journal Neurology.

Researchers surveyed about 16,000 people in their homes in 15 states. In the survey, researchers asked volunteers about the lifestyle including their health, sleeping habits and about any type of disorders such as sleep walking.

“We did not know what was the prevalence of sleepwalking – as a disorder – in the general population, and that was a big problem,” said Maurice Ohayon, director of the Stanford Sleep Epidemiology Research Center in California, who led the research.

Researchers have found that about 3% of people walked in sleep at least one time in a year and once in a month and 1% of people said that they sleepwalked at least two times in a month. They have found that people with sleep apnea or insomnia or depression, people with habit of heavy drinking and people who have the habit of taking sleeping pills. The research team has reported that one-third of sleepwalkers also said that they have a family history of sleepwalking.

The research was funded partially by the U.S. National Institutes of health, the Arrillaga Foundation, the Bing Foundation and Neurocrines Biosciences that is a biopharmaceutical company.
