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.Another major cause of this sleep eating subtype of sleepwalking is sleep medication, such as Ambien for example (Mayo Clinic).
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.
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.
Also noteworthy is the report of familial presence of parasomnia.
Studies of twin cohorts and families with sleep terror and sleepwalking suggest genetic involvement of parasomnias.
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.
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.
