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.
During the period of 10 years, 274 CVD deaths were observed while the recalibrated risk chart predicted 263 events. The SCORE Belgium risk chart showed very good accuracy over the complete range of predicted risk (Hosmer-Lemeshow: P=0.14). ROC analysis revealed excellent discriminatory power in labelling future cases of fatal cardiovascular disease with a c-statistic of 0.86. The 5% threshold for the probability of 10-year cardiovascular death yielded an optimal balance of sensitivity and specificity.
