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.
Behavioral studies suggest that up to 2 to 3 standard drinks before bedtime initially promotes sleep, but these effects diminish in as few as 3 days of continued use. Clinical investigations support a relationship between sleep disturbance and alcohol use, but variability in the definition and measurement of these domains and a preponderance of cross-sectional studies make uncertain the strength and direction of the association.
