Do people with dementia wander at night? A guide to risks and safety

An estimated six out of ten people with dementia will wander at some point during their illness, and this behavior frequently occurs or intensifies during the night. It is a serious safety concern for caregivers that is often tied to the phenomenon known as 'sundowning'. This guide explores why people with dementia wander at night and provides actionable strategies for managing this behavior.

Quick Summary

Yes, nighttime wandering is a common and dangerous symptom of dementia, often linked to 'sundowning' where confusion and agitation increase in the evening. This behavior is caused by disrupted sleep cycles, disorientation, and unmet needs, requiring caregivers to implement safety measures and consistent routines to protect their loved ones.

Key Points

• Prevalence: Up to 60% of people with dementia may wander, and this behavior is often exacerbated at night.

• Sundowning Effect: Increased confusion and restlessness in the late afternoon and evening is a major cause of nighttime wandering.

• Safety is Paramount: Unaddressed wandering can lead to serious injury or death, emphasizing the need for proactive safety measures.

• Environmental Adaptation: Home modifications like secure locks, alarms, and better lighting are essential for creating a safe environment.

• Routine and Redirection: Establishing a calm, consistent nightly routine and using gentle redirection are effective behavioral management strategies.

• Technology as a Tool: GPS trackers and motion sensors can provide valuable alerts and aid in locating a loved one if they wander.

Understanding the Phenomenon of Nighttime Wandering

Nighttime wandering is one of the most stressful and dangerous behaviors for family caregivers of a loved one with dementia. It is not an act of defiance but a symptom of the disease's progression, resulting from a combination of physiological and psychological factors. The term 'sundowning' describes a state of increased confusion and anxiety that can occur in the late afternoon and continue into the night, directly contributing to restlessness and the urge to wander.

The Core Reasons Behind Wandering at Night

Several factors can trigger or contribute to a person with dementia wandering during the night:

• Disrupted Circadian Rhythms: Dementia damages the parts of the brain that regulate the body's internal clock, or sleep-wake cycle. This can cause a person to feel awake and restless when they should be sleeping.
• Sundowning Syndrome: The onset of dim light can increase confusion and visual misperceptions. Shadows and low light can cause fear and anxiety, prompting a person to seek safety or escape.
• Disorientation and Memory Loss: A person may wake up and feel disoriented, believing they are in a different place or time. They might try to 'go home' to a house from their past or search for a past responsibility, such as preparing for work or caring for a child.
• Unmet Needs: Simple needs like hunger, thirst, or needing to use the bathroom can prompt a search. Because of their cognitive impairment, they may not be able to express these needs clearly and will wander in search of a solution.
• Boredom and Lack of Stimulation: Too much napping during the day or a lack of engaging activities can lead to excess energy and restlessness at night.

The Risks Associated with Night Wandering

The risks involved with nighttime wandering are significant and must be taken seriously by caregivers. It is reported that up to half of those with dementia who wander and are not found within 24 hours face serious injury or death. Key risks include:

• Getting Lost Outdoors: A person can easily become lost in the dark, even in familiar surroundings, and may not have the judgment to seek help.
• Exposure: Inappropriate clothing for the weather can lead to hypothermia or heatstroke, depending on the season.
• Falls and Injury: Moving around in a dark, unfamiliar, or cluttered environment increases the risk of tripping, falling, and suffering injuries.
• Caregiver Burnout: Constant vigilance and disturbed sleep can lead to immense stress and exhaustion for caregivers, which is a major reason for institutionalization.

Practical Strategies for Managing and Preventing Night Wandering

Proactive management of nighttime wandering is crucial for the safety and well-being of both the person with dementia and their caregiver. A combination of environmental adjustments, routine management, and technology can significantly reduce risks.

Creating a Safe Home Environment

• Install safety locks on all exterior doors, placing them either high or low out of the person’s line of sight.
• Use motion sensors or pressure-sensitive mats that can alert you if the person gets out of bed or opens a door.
• Place nightlights in bedrooms, hallways, and bathrooms to reduce disorientation in the dark.
• Strategically camouflage doors with paint or curtains to reduce visual cues that encourage exiting.
• Clear pathways of clutter, furniture, and tripping hazards, and ensure all area rugs are secure.
• Store items that might trigger wandering, such as car keys, purses, and coats.

Developing a Calming Nighttime Routine

1. Maintain a Consistent Daily Schedule: A predictable routine for waking, meals, and bedtime helps regulate the body's internal clock.
2. Encourage Daytime Activity: Supervised exercise or a walk outside can reduce restlessness and promote better sleep.
3. Plan Quiet Evening Activities: Engage in low-energy, calming activities before bed, such as listening to soft music or folding laundry.
4. Limit Daytime Naps: If possible, reduce or shorten naps to promote tiredness at night.
5. Address Needs Before Bed: Ensure the person has used the bathroom and is comfortable (not too hot or cold) before settling in for the night.
6. Provide Reassurance: If they express a desire to 'go home,' gently redirect them instead of arguing. Reassure them that they are safe.

Comparing Wandering Management Techniques

Environmental Modification	Highly effective for prevention; creates a safer space; empowers caregiver to take proactive steps.	Can be expensive; requires consistent implementation; some measures may feel restrictive.
Routine Management	Promotes a sense of security and predictability; can reduce overall anxiety and agitation.	Requires consistent effort from caregivers; may be difficult to implement initially with resistant individuals.
Assistive Technology	Provides peace of mind and quick alerts; allows for monitoring without constant presence; GPS trackers can aid search efforts.	Can be costly; requires technical setup; raises privacy concerns for some families.
Behavioral Redirection	Gentle and non-confrontational; respects the person's emotions; helps de-escalate situations.	May not work every time; requires patience and creativity from the caregiver.

The Role of Technology and Professional Support

Technological tools and external support services can provide invaluable assistance. GPS tracking devices, worn as bracelets or pendants, can help locate a lost individual quickly. Services like MedicAlert + Alzheimer's Association Safe Return® offer a nationwide identification program to assist in the return of lost individuals. Caregivers can also benefit from enrolling in training or joining support groups to share experiences and learn effective strategies for managing challenging behaviors.

Conclusion: Proactive Care for Safer Nights

Nighttime wandering is a serious and challenging aspect of dementia care, but it is manageable. By understanding the root causes, implementing effective safety measures, establishing consistent routines, and utilizing available technology, caregivers can significantly reduce the risks. A proactive, patient, and compassionate approach not only ensures the safety of the person with dementia but also provides much-needed peace of mind for the caregiver.
