Because many sleep eaters prepare the food they consume, there are risks involving burns and such with ovens and other appliances.
As expected, weight gain is also a common outcome of this disorder, because food that is frequently consumed contains high carbohydrates.
Polysomnography is the only accurate assessment of a sleepwalking episode.
Because this is costly and sleepwalking episodes are usually infrequent, other measures commonly used include self-, parent-, or partner-report.
Also, patients with migraine headaches or Tourette Syndrome are 4–6 times more likely to sleepwalk. One study found that sleepwalking occurred in 45% of children who have one parent who sleepwalked, and in 60% of children if both parents sleepwalked.
Most sleepwalkers had injuries at some point during sleepwalking, often minor injuries such as cuts or bruises. Sleepwalking may be inherited as an autosomal dominant disorder with reduced penetrance.Children's respiration during sleep should be monitored with nasal cannula or pressure transducer system or esophageal manometry, which are more sensitive than the thermistors or thermocouples currently used in many laboratories.The clear, prompt improvement of severe parasomnia in children who are treated for SDB, as defined here, provides important evidence that subtle SDB can have substantial health-related significance.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.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".They may talk while sleepwalking, but the talk typically does not make sense to the observer.There are varying degrees of amnesia associated with sleepwalking, ranging from no memory at all, vague memories or a narrative.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.
