Specific neurobiological triggers cause sleepwalking episodes
Evidence indicates that sleepwalking (somnambulism) and related NREM parasomnias are associated with specific precipitating factors and underlying neurobiological mechanisms involving state dissociation during sleep.
The provided papers on sleepwalking, NREM parasomnias, and related arousal disorders consistently point to specific triggers (such as sleep deprivation and stress) and underlying neurobiological mechanisms involving state dissociation. Therefore, the claim is supported by the retrieved literature.
