Managing Wandering in Alzheimer's: A Guide for Neurologists and Caregivers

Alzheimer’s disease (AD) is a progressive neurological disorder that impairs memory, cognition, and the ability to perform daily tasks. One of the most challenging and potentially dangerous symptoms of Alzheimer’s is wandering. It is estimated that 60% of individuals with AD will wander at some point during the course of their illness. When someone with Alzheimer’s wanders, they may become lost, confused, and exposed to serious physical harm, such as accidents or harsh weather conditions.

In this comprehensive guide, we will explore the reasons behind wandering, how to prevent it, and what to do when someone with Alzheimer’s disease does wander. This guide is designed for neurologists, caregivers, and healthcare professionals seeking to provide optimal care and safety for individuals with AD.

Understanding Wandering in Alzheimer’s Disease

Why Do People with Alzheimer’s Wander?

Wandering in Alzheimer’s patients can stem from several causes, often related to the disease's impact on cognitive functions. Understanding the underlying reasons is essential for neurologists and caregivers to manage and mitigate wandering behaviors.

1. Disorientation and Confusion
   Individuals with Alzheimer’s may become confused about their surroundings, time of day, or current location. They may believe they are in a different place, trying to return to a familiar setting from their past, or think they need to complete a long-abandoned task, such as going to work or picking up children.
2. Memory Loss
   Short-term memory is often one of the first aspects affected by Alzheimer’s disease. A patient may forget where they are or where they were going, prompting them to wander in search of answers. In extreme cases, they may forget their identity, which leads them to explore in a state of confusion.
3. Anxiety and Stress
   Environmental changes, loud noises, or new people in their living space can induce stress and anxiety, leading individuals with AD to wander in search of a calmer environment. Anxiety also worsens at certain times of the day, especially in the evening—a phenomenon known as "sundowning."
4. Restlessness and Boredom
   Sometimes wandering can be attributed to restlessness or a need for stimulation. Individuals who used to lead active lives may wander to relieve feelings of boredom or frustration, especially when their physical activity is limited by caregivers.
5. Physical Discomfort
   Unmet physical needs, such as hunger, thirst, or needing to use the restroom, can also trigger wandering. People with Alzheimer’s may be unable to communicate these needs effectively, so they resort to wandering as an attempt to satisfy them.
6. Habitual Behaviors
   Past routines can play a role in wandering. For example, if someone used to take a walk every evening, they may continue to do so even if they no longer recognize their neighborhood or surroundings.

Preventing Wandering: Proactive Measures

Preventing wandering is an essential part of Alzheimer’s care. Neurologists and caregivers must work together to implement strategies that minimize wandering risk while maintaining the patient's dignity and autonomy.

1. Create a Safe Environment

• Secure Exits: Install locks on doors and windows, but make sure they are out of sight or difficult to operate for someone with cognitive impairment. A more advanced solution is to install a security system or motion detectors to alert caregivers if the patient tries to leave the house.
• Use Visual Cues: Place clear signs around the home, such as arrows or labels, to help guide the patient and minimize confusion. Mirrors, in some cases, can be disorienting and may need to be removed.
• Disguise Doors: Camouflaging doors with curtains or paintings can reduce the patient’s desire to open them. Some caregivers place a "STOP" sign on doors, which can be enough of a visual cue to discourage wandering.

2. Provide Supervision

• Caregiver Presence: Ensure that someone is always with the patient, especially during high-risk times, such as the evening. In some cases, hiring professional caregivers for 24-hour supervision may be necessary.
• Engage in Activities: Keeping the person engaged in mentally stimulating and physically active tasks can reduce restlessness. Incorporating familiar routines and activities can offer comfort and minimize wandering behavior.

3. Technology for Wandering Prevention

• GPS Tracking Devices: Many devices now come equipped with GPS tracking, allowing caregivers to locate a wandering individual quickly. Devices may come in the form of wristbands, necklaces, or even shoes.
• Alarm Systems: Install door alarms that trigger when the patient tries to leave the home. These can be helpful in ensuring quick responses if wandering occurs.
• Remote Monitoring: For patients living at home or in semi-independent environments, remote monitoring cameras allow caregivers to keep an eye on the patient even from afar.

4. Address Underlying Causes

• Treat Anxiety and Agitation: For patients experiencing anxiety or sundowning, consider behavioral interventions, calming environments, or medications when appropriate.
• Review Medications: Ensure that the patient’s medications are not contributing to increased confusion or restlessness. Neurologists should regularly assess and adjust prescriptions as needed.

5. Personal Identification

• Medical ID Bracelets: Make sure the person always wears a medical identification bracelet or carries ID cards with their name, diagnosis, and caregiver contact information.
• Photo Documentation: Keep recent photographs of the patient available in case of an emergency to help authorities and caregivers find them faster.

What to Do When Someone with Alzheimer’s Disease Wanders

Despite all preventive measures, wandering can still occur. It is crucial to have a well-thought-out action plan for when wandering happens.

1. Stay Calm and Begin Searching Immediately

Time is of the essence when someone with Alzheimer’s wanders. The first few hours are critical in ensuring the person’s safety.

• Search Nearby: Start by checking rooms, closets, or familiar locations where the person might think they should be.
• Call Friends and Neighbors: Inform local friends, neighbors, or nearby businesses of the wandering, as they might have seen the person or can assist in the search.
• Notify Local Authorities: If the search within the immediate vicinity doesn’t yield results, contact the police or local authorities. Explain the person's condition and share recent photographs and identifying information.

2. Leverage Technology for Quick Location

If the person is wearing a GPS tracking device, use it to find their location as quickly as possible. Having this technology in place can significantly reduce the time it takes to locate them.

3. Create a Lost Person’s Kit

Caregivers should have a prepared "lost person’s kit" in the event of wandering. This kit should contain:

• A recent photo of the person
• Their medical history, including medications they need
• Contact information for their healthcare providers and family members
• A list of familiar places or locations where they might be inclined to go

4. Inform the Local Community

Alzheimer’s disease affects millions of people, and the chances of someone encountering a wandering individual are high. Encourage the local community to become familiar with the signs of dementia-related wandering. Organizing community education programs or training first responders can help make neighborhoods safer for people with Alzheimer’s.

5. Use the MedicAlert® and Alzheimer’s Association Safe Return® Program

This program is a nationwide network designed to help locate people with dementia when they wander. It works by using the MedicAlert medical ID bracelets that register the patient’s information in a national database. Should they wander, local authorities can quickly access vital information to reunite them with caregivers.

Addressing Wandering in Healthcare Settings

1. Hospitals and Nursing Homes

Patients with Alzheimer’s who are hospitalized or live in nursing facilities are still at risk of wandering. Neurologists should work closely with facility staff to implement appropriate safeguards:

• Wander-Prevention Units: Some long-term care facilities have designated areas with secure exits, alarms, and increased supervision.
• Staff Training: Train hospital and nursing home staff to recognize early signs of wandering, especially in patients who have exhibited wandering behavior in the past.

2. Caregiver Support

Neurologists should encourage caregivers to join support groups or seek counseling when managing a loved one prone to wandering. Managing a person with Alzheimer’s disease can be exhausting, and providing caregivers with education, respite care, and emotional support is vital.

When Wandering Results in Injury or Hospitalization

If wandering leads to an injury, immediate medical attention is necessary. Neurologists should evaluate the patient for any cognitive decline that might have contributed to the event and recommend further interventions to prevent future occurrences. Recurrent episodes may signal the need for a more secure environment, such as a memory care facility.

Conclusion

Wandering is a serious concern for individuals with Alzheimer’s disease, and prevention requires a proactive, multifaceted approach. Neurologists, caregivers, and healthcare professionals must collaborate to create safe environments, utilize technology, and address the behavioral and cognitive triggers that lead to wandering. Early intervention, careful monitoring, and the use of community and technological resources can help prevent wandering and ensure the safety of individuals with Alzheimer’s.
