Wandering behavior

Wandering behavior is purposeless locomotion usually due to a disturbed mental state or mental confusion.

Wandering in dementia
Wandering, in persons with dementia, is a common behavior that causes great risk for the person and concern for caregivers. It is estimated to be the most common type of disruptive behavior in institutionalized persons with dementia. Although it occurs in several types of dementia, wandering is especially problematic in persons with Alzheimer's disease (AD). This is because AD frequently produces impaired memory: persons with impaired memory are likely to become disoriented and lost simply because they do not recognize where they are nor remember how they came to be there.
