Sleepwalking is a disorder that causes people to get up and walk while they're asleep. It usually happens when a person is going from the deep stage of sleep to a lighter stage or into the awake state. The sleepwalker can't respond during the event and usually doesn't remember it. In some cases, he may talk and not make sense.
When someone sleepwalks, they might quietly walk around their room. Or they might run or attempt to "escape." Typically, the sleepwalker's eyes are open with a glassy stare as he roams the house. If you question him, he'll be slow to respond or not respond at all. When you get him back to bed without waking him up, he usually won't recall the event. Older children may wake up more easily at the end of a sleepwalking episode.
The prevalence of bruxism was 26.2%. Bruxism begun in average at the age of 4.9±2 years. Also it occurred 2.6 times more in children who had a family history of bruxism (father-mother), compared to children who didn't have such a history. 87% of children with bruxism had a history of distressing events in their life, and 13% of children with bruxism did not report any history of distressing events in their life.
