Question

practice it
sleep - wake disorder characterized by repeated episodes of sleepwalking
sleepwalking disease
sleepwalking abnormality
sleepwalking symptom
sleepwalking disorder
sleepwalking schizophrenia

Explanation:

Sleepwalking disorder is the recognized term for a sleep - wake disorder with repeated sleepwalking episodes. "Sleepwalking disease" is not the standard term. "Sleepwalking abnormality" is too vague. A "sleepwalking symptom" would be part of a disorder, not the disorder itself. "Sleepwalking schizophrenia" is incorrect as schizophrenia is a different mental health condition not related to sleepwalking in this context.

Answer:

sleepwalking disorder
