Sleepwalkers often have little or no memory of the incident, as their consciousness has altered into a state in which memories are difficult to recall.
Although their eyes are open, their expression is dim and glazed over.
The sleepwalker's eyes are open but may appear as a glassy-eyed stare or blank expression and pupils are dilated.
They are often disoriented, consequent to awakening: the sleepwalker may be confused and perplexed, and might not know why or how they got out of bed; however, the disorientation will fade within minutes.
it was found that, if a child had another sleep disorder – such as restless leg syndrome (RLS) or sleep-disorder breathing (SDB) – there was a greater chance of sleepwalking.
The study found that children with chronic parasomnias may often also present SDB or, to a lesser extent, RLS.having conversations or driving a vehicle), however the brain does not create memories for the events.A systematic review of the literature found that approximately 50% of drinkers have experienced memory loss during a drinking episode and have had associated negative consequences similar to sleepwalkers, including injury and death. These sleep eating disorders are more often than not induced for stress related reasons.In some cases, sleepwalking in adults may be a symptom of a psychological disorder.One study suggests higher levels of dissociation in adult sleepwalkers, since test subjects scored unusually high on the hysteria portion of the "Crown-Crisp Experiential Index".It occurs during slow wave sleep stage, in a state of low consciousness, with performance of activities that are usually performed during a state of full consciousness.These activities can be as benign as talking, sitting up in bed, walking to a bathroom, and cleaning, or as hazardous as cooking, driving, Although sleepwalking cases generally consist of simple, repeated behaviors, there are occasionally reports of people performing complex behaviors while asleep, although their legitimacy is often disputed.Furthermore, the disappearance of the parasomnias after the treatment of the SDB or RLS periodic limb movement syndrome suggests that the latter may trigger the former.The high frequency of SDB in family members of children with parasomnia provided additional evidence that SDB may manifest as parasomnias in children.As with sleepwalking, there are ways that sleep eating disorders can be maintained.There are some medications that calm the sleeper so they can get longer and better-quality rest, but activities such as yoga can also be introduced to reduce the stress and anxiety causing the action.
