Families should seek medical care for exit-seeking — repeated attempts by a person with dementia to leave home or a care setting — whenever the behavior appears suddenly, escalates quickly, or follows an illness or medication change. A gradual, long-standing pattern still deserves a scheduled evaluation, but an abrupt surge in door-testing or elopement attempts warrants a same-week medical workup, and a person who has actually left and cannot be found within 15 minutes is a 911 emergency.
Exit-seeking is not a fringe problem to hope away. According to Alzheimer's Association guidance on wandering, six in 10 people living with dementia will wander at least once, and many do so repeatedly. Knowing which situations call for a doctor, which call for emergency services, and which call for a care-planning visit lets families respond to the right problem at the right speed.

The emergency line: when to call 911
If your family member has left and you cannot locate them within 15 minutes, call 911 and tell responders the missing person has dementia. That 15-minute threshold comes directly from the Alzheimer's Association, which also reports that up to half of wanderers not found within 24 hours suffer serious injury or death. This is not a situation for an extended family search first; time is the main risk factor. Two details improve the odds.
Most wanderers are found within half a mile of where they started, so searchers should begin close and work outward. And the Alzheimer's Association runs a 24/7 helpline at 800-272-3900 and recommends enrolling in a wandering-response service such as MedicAlert before a crisis, so responders have a photo, description, and medical details ready. An emergency-room visit is also appropriate after a person is found if they were exposed to heat, cold, or injury, even when they insist they feel fine. People with dementia often cannot reliably report pain or dehydration.
Sudden exit-seeking is a medical symptom, not just a behavior
A new or sharply worsening drive to leave — especially over days rather than months — should be treated as a possible sign of illness. The National Institute on Aging advises caregivers to bring sudden or rapidly fluctuating behavior changes, including new wandering, to a doctor promptly, particularly after a recent infection or medication change, according to NIA guidance on coping with wandering. The reason is delirium: abrupt confusion or out-of-character behavior that develops over one to two days.
The Alzheimer's Society explains that delirium is serious but treatable, and the only treatment is finding and resolving the underlying illness — which is why it requires prompt medical evaluation rather than watchful waiting. Urinary tract infections are a classic culprit. The Alzheimer's Society's guidance on UTIs and dementia documents that UTIs can trigger sudden confusion, agitation, and behavior change, and that the confusion usually improves once the infection is treated. Practically: an unexplained surge in exit-seeking deserves a same-week appointment and likely a urine test, not just new door locks.
What a good medical visit should look like
Expect detective work, not a prescription pad. Clinical guidance published by the American Academy of Family Physicians directs clinicians to first assess and treat physical causes of dementia behaviors — pain, thirst, hunger, constipation, toileting difficulty, and environmental discomfort — because these commonly drive behaviors like wandering. A person who cannot say "my back hurts" or "I need a bathroom" may show it by trying to leave. Come prepared with a brief log: when the exit attempts happen, what preceded them, what the person says while trying to leave, and any recent changes in medication, sleep, appetite, or bowel habits.
Time-of-day patterns matter; attempts clustered in late afternoon point to different causes than attempts after every meal. One thing you should not expect — or accept without hard questions — is sedation. Per AAFP's Choosing Wisely guidance, wandering is not an appropriate target for antipsychotic drugs; there is no drug treatment for it, and an FDA meta-analysis found 4.5% mortality in antipsychotic-treated dementia patients versus 2.6% on placebo. If an antipsychotic is proposed specifically for exit-seeking, ask what underlying cause was ruled out first.
The non-urgent visit: building a plan around the pattern
Even without a sudden change, chronic exit-seeking justifies a scheduled visit with the primary clinician or a dementia-care team. The Administration for Community Living recommends assessing the patterns, frequency, and triggers of wandering — with particular attention to unmet needs — and building a person-centered plan from that baseline.
This is the visit where you address the behavior's meaning: some people are "going to work," some are searching for a person or a former home, some are simply restless or overstimulated. A plan built this way typically pairs medical steps with practical ones: Revisit the plan whenever the pattern shifts. A change in when or why the person tries to leave is itself new information for the clinician.
- Treat identified drivers such as pain, constipation, or infection.
- Adjust routines to add supervised walking or activity at high-risk times of day.
- Reduce triggers, like visible coats and keys near the door or a chaotic late-afternoon environment.
- Layer in safety measures: ID jewelry, a wandering-response enrollment, and neighbor awareness.
Quick reference: which response fits which situation
The half-mile statistic is worth acting on today: because most wanderers are found close to home, a current photo, a list of likely destinations (former workplaces, old addresses, favorite places), and briefed neighbors are among the highest-value preparations a family can make before any emergency happens.
- Person is missing and not found within 15 minutes: call 911 and state that the person has dementia.
- Exit-seeking appeared or escalated over days, or followed an illness or new medication: request a medical appointment within the week to check for delirium, infection, or drug effects.
- Person was outside in dangerous conditions or may be injured: seek same-day care even if they seem unharmed.
- Long-standing, stable exit-seeking: schedule a non-urgent visit to assess triggers and unmet needs and build a written plan.
- Any stage, any pattern: enroll in a wandering-response service and keep the Alzheimer's Association 24/7 helpline, 800-272-3900, accessible to every caregiver in the household.
Frequently Asked Questions
Can medication stop my parent from trying to leave the house?
No. AAFP's Choosing Wisely guidance states there is no drug treatment for wandering, and antipsychotics raise mortality risk in dementia. Treatment targets underlying causes such as pain, infection, or unmet needs.
Why would a bladder infection make someone try to leave home?
Infections can cause delirium — sudden confusion and out-of-character behavior developing over one to two days. The Alzheimer's Society notes UTI-related confusion usually improves once the infection is treated.
Should I wait to see if a missing person comes back on their own?
No. If they are not found within 15 minutes, the Alzheimer's Association says to call 911, because up to half of wanderers missing more than 24 hours suffer serious injury or death.
