Seek prompt professional help when nighttime wandering starts suddenly, worsens rapidly, or appears with new confusion or agitation. Arrange a clinical review when it continues despite changes to daily routines, daytime activity, the sleep environment, and evening caffeine or alcohol. The NHS describes nighttime wandering as repeatedly getting up, becoming disoriented, or dressing because the person does not recognize that it is nighttime. It requires attention because a person who leaves a safe setting may become lost or seriously harmed.

A sudden change needs prompt assessment
A new or rapidly worsening pattern may reflect more than dementia. The NHS advises prompt medical assessment because pain, constipation, infection, or medication side effects can cause behavior changes beyond those caused by dementia.
Do not automatically label new wandering as sundowning. Sundowning means increased confusion from dusk through the night and may include pacing, agitation, anxiety, insomnia, hallucinations, or disorientation. Its exact cause is unknown, so a sudden change still warrants assessment.
When persistent wandering needs a clinical review
If the pattern is not sudden, first consider whether practical changes have had a fair trial. The NHS recommends arranging a review when sleep problems or wandering continue despite routine and environmental measures, including: Keep a brief record while trying these measures.
Note when the person gets up, what they appear to be doing, daytime activity, evening drinks, toileting concerns, and recent medication changes. This can give the clinician a clearer pattern to investigate.
- A consistent daily and bedtime routine
- Activity and daylight during the day
- Changes that make the nighttime environment easier to understand
- Less caffeine and alcohol in the evening
What should the clinician investigate?
Sleep disruption may have a treatable contributor. The Alzheimer's Association identifies urinary infections, incontinence, restless legs syndrome, and sleep apnea as conditions that can cause or worsen sleep problems in someone with dementia.
The clinician can also consider pain, constipation, and medication side effects. Bring an up-to-date medication list and describe exactly what changed, rather than reporting only that the person "wanders." Details such as repeated bathroom trips, pacing, dressing, or trying to leave may help distinguish different problems.
Is medication the next step?
Medication is not the default response to Alzheimer-related sleep disturbance. The Alzheimer's Association says most experts favor non-drug measures before sleep medication.
If those measures fail, ask the clinician what problem a proposed medication is intended to address and how its risks and benefits apply to this person. A medication discussion should follow an assessment for other causes rather than replace one.
When wandering becomes a safety emergency
A previous wandering episode is enough reason to seek professional help with a safety plan. The National Institute on Aging advises not leaving the person unattended and recommends identification, location tracking, door alarms, and notifying neighbors and local police.
A practical plan should establish: If the person is missing, begin searching immediately. The Alzheimer's Association advises calling 911 after 15 minutes if the person has not been found and telling the dispatcher that the missing person has dementia.

- What identification the person carries
- Whether a location-tracking option is available
- Who will search nearby areas
