Dementia & Safety Guide

Your Elderly Parent Is Wandering at Night. Here's What You Need to Know.

You got a call at 3am. Your parent was found outside in their pyjamas, confused, half a kilometre from home. Or maybe a neighbour found them in the garden at midnight. The fear you felt in that moment is something no child forgets.

Night-time wandering is one of the most frightening and exhausting challenges families face when caring for an elderly parent. It's also one of the most dangerous — and one of the most common reasons families ultimately consider residential care. But before you reach that point, there are things you can do.

How Common Is Night Wandering?

60%

Of people with dementia will wander at some point during their illness

Reason families move an elderly parent into residential care is wandering behaviour

50%

Of wanderers who are not found within 24 hours risk serious injury or death

472,000

Australians live with dementia in 2026, projected to reach 590,000 by 2028

Critical Safety Warning

If your parent has wandered outside the home at night even once, treat it as a safety emergency that requires immediate action. Do not wait for it to happen again. The risks — falls, exposure, traffic, getting lost — are too severe.

10 Reasons Elderly People Wander at Night

Understanding the cause determines the solution. Not all wandering is the same, and not all wandering is dementia.

#	Cause	What You'll Notice	Key Action
1	Dementia (Alzheimer's)	Confused about time/place, may be “going to work” or “going home”	GP cognitive assessment
2	Sundowner's Syndrome	Agitation increases as daylight fades, peaks 4pm–midnight	Light therapy, routine changes
3	Medication side effects	Restlessness, confusion after recent drug changes	GP medication review
4	Sleep disorders	Wakes confused, may have REM sleep behaviour disorder	Sleep study referral
5	Pain or discomfort	Gets up and walks because lying down hurts (arthritis, neuropathy)	Pain management review
6	UTI-induced delirium	Sudden onset confusion, agitation, may not have urinary symptoms	Urgent GP — urine test
7	Bathroom needs	Gets disoriented searching for the bathroom in the dark	Night lights, commode
8	Hunger or thirst	Forgot to eat dinner, wakes hungry and confused	Evening snack routine
9	Anxiety or fear	Hears noises, feels unsafe, tries to “escape” perceived threat	Security measures, evening call
10	Boredom or restlessness	Insufficient daytime activity, reversed sleep-wake cycle	Daytime activity programs

The Immediate Dangers of Night Wandering

The risks of night wandering extend far beyond getting lost. For an elderly person — especially one with cognitive impairment — the consequences can be life-threatening within hours.

Falls & Fractures

Navigating in darkness, on uneven surfaces, without shoes. Hip fractures in people over 80 carry a 30% mortality rate within 12 months. Inside the home, stairs, step-downs, and loose rugs are lethal hazards at night.

Hypothermia & Heat Exposure

Elderly people lose body heat faster due to reduced circulation and less body fat. In winter, hypothermia can set in within 30–60 minutes outdoors in pyjamas. In Australian summer, heat stroke is equally dangerous for wanderers found hours later.

Traffic & Roads

A confused person walking on roads at 3am in dark clothing is nearly invisible to drivers. Pedestrian fatalities among over-75s are disproportionately high between 10pm and 6am.

Getting Lost & Inability to Return

A person with dementia who wanders even 200 metres from home may be unable to find their way back. They may not be able to tell a stranger their name, address, or phone number. Without ID, they may end up in an emergency department as an “unknown person.”

Dehydration & Medical Events

If not found quickly, wanderers miss medications, become dehydrated, and may experience falls, strokes, or cardiac events with no one nearby to call for help.

Is It Sundowner's Syndrome?

Sundowner's syndrome (also called sundowning) is a pattern of increased confusion, agitation, anxiety, and restlessness that begins in the late afternoon and evening. It affects an estimated 20–45% of people with Alzheimer's disease and is one of the most common triggers for night wandering.

Sundowner's Checklist

Agitation or restlessness starts between 3pm and 6pm

Becomes suspicious, anxious, or angry as evening approaches

Insists on “going home” even when they are at home

Paces, wanders, or tries to leave the house after dark

Behaviour is significantly worse in the evening compared to morning

May not recognise family members or surroundings in the evening

What Helps With Sundowner's

Bright light therapy (10,000 lux light box for 30 minutes in the morning), maintaining a strict daily routine, limiting caffeine after midday, ensuring adequate daytime activity, and keeping the home well-lit in the evening hours. Some GPs prescribe low-dose melatonin. An evening check-in call at a consistent time can also help anchor the person's sense of routine and time.

Home Safety Modifications for Night Wandering

The goal is to make the home safe to wander in, while preventing the person from leaving the house undetected. This is not about locking them in — it's about creating a safe environment.

Door & Exit Safety

• Install door alarms that chime when opened (battery-operated, $20–$50)
• Place deadbolts high or low on doors — out of the person's visual field
• Use childproof covers on door handles
• Place a dark-coloured mat in front of exits — people with dementia often perceive it as a hole and avoid stepping on it
• Disguise exits with curtains or decorative panels over the door

Lighting & Navigation

• Motion-sensor night lights in hallways, bathroom, and bedroom
• Remove tripping hazards: loose rugs, power cords, low furniture
• Handrails on both sides of hallways and stairs
• Clear, straight paths from bedroom to bathroom
• Fluorescent tape along floor edges and step edges

Monitoring & Alerts

• Bed pressure sensor that alerts when they get up
• Motion sensor in hallway that sends phone notification
• GPS tracker on a belt, in a shoe, or as a watch
• Daily wellness check-in calls to detect changes in sleep pattern and confusion levels over time
• Baby monitor or two-way audio device in their bedroom

Garden & Outdoor Safety

• Secure side gates with key locks (not latches)
• Fence any pools or water features (legal requirement in most states)
• Solar-powered garden lights along paths
• Remove or lock garden sheds (tools, chemicals)
• Consider a safe, enclosed garden area for night wandering

Financial Assistance for Home Modifications

Home modifications for safety can be funded through a Home Care Package (Levels 1–4 via My Aged Care) or the Commonwealth Home Support Programme (CHSP). An occupational therapist can assess the home and recommend modifications — this assessment is Medicare-subsidised with a GP referral. Your local council may also have a Home Maintenance and Modification program.

GPS Tracking Options for Wanderers

If your parent has wandered outside the home, a GPS tracker provides a critical safety net. The best device is the one they will actually wear or carry.

Device Type	Pros	Cons	Cost (AUD)
GPS watch	Worn like a normal watch, SOS button, geofencing	Must be charged daily, may remove it	$150–$400 + $10–$30/mo
Shoe insert tracker	Hidden, can't be removed easily	Only works if wearing shoes, limited battery	$200–$350 + subscription
Pendant/clip-on tracker	Lightweight, can clip to belt or clothes	May be removed, left behind, or lost	$100–$250 + $10–$20/mo
Apple AirTag / Tile	Cheap, long battery, can sew into clothing	Bluetooth only — relies on nearby iPhones/Tiles for location. Not real-time GPS	$39–$50 (no subscription)

Neighbourhood Alert

Introduce yourself to immediate neighbours and explain the situation. Give them your phone number and ask them to call you if they see your parent outside at unusual hours. Many families also register with their local police station — police can keep a “vulnerable person” file with a photo, description, and your contact details. If your parent goes missing, this file dramatically speeds up the search.

How Evening & Night Check-In Calls Help

One of the most effective interventions for night wandering is remarkably simple: a daily evening phone call. Here's why it works and what the evidence shows.

Anchors the Evening Routine

A consistent call at, say, 7pm acts as a “time anchor.” For people with dementia who lose track of time, the call signals “the day is winding down, it's time to settle.” This helps prevent the confusion that triggers wandering.

Reduces Anxiety Before Bed

Talking to another person — even for five minutes — can significantly reduce the anxiety and agitation that peaks in the evening (sundowning). It gives the person a sense that someone is watching over them.

Detects Changes Early

Daily calls create a baseline. When confusion increases, speech becomes muddled, or the person reports not sleeping, you get early warning — often days before a wandering episode. This allows you to intervene before a crisis.

Medication & Routine Reminders

The call can include gentle reminders: “Have you taken your evening tablets? Have you locked the front door?” For people in early-to-mid dementia, these prompts can be enough to maintain safe routines.

When Night Wandering Means Residential Care Is Needed

There is no formula for this decision, and there is no shame in it. Residential care exists because some levels of care are beyond what can be safely provided at home. Consider the transition if:

• Wandering occurs multiple times per week despite home modifications and interventions
• They have been found outside the home or property
• They become aggressive when redirected (a sign of advancing dementia)
• Your own health is suffering from sleep deprivation and constant vigilance
• They need 24-hour supervision and you cannot provide it
• The GP, geriatrician, or ACAT team recommends residential care

Legal Considerations

You cannot legally lock a competent person inside their home. If your parent has dementia and lacks decision-making capacity, an Enduring Power of Attorney or Guardianship Order may be needed to make accommodation decisions on their behalf. Contact the Office of the Public Guardian in your state for guidance. Early legal planning — while your parent still has capacity — is always better.
