Wandering is one of the most urgent safety issues families face when a loved one has Alzheimer's disease or another dementia. This guide explains San Diego aging figures, practical home safety steps, and how in-home supervision reduces the chance that someone leaves unnoticed.
Local Aging and Alzheimer's Figures in San Diego
San Diego has 196,289 residents age 65 and older and 23,020 residents age 85 and older, according to U.S. Census Bureau American Community Survey estimates. The same Census estimates show 46,031 seniors living alone and a median household income of $104,321. These are city-level figures for San Diego, not statewide totals.
An estimated 21,810 residents may be living with Alzheimer's disease specifically, based on national Alzheimer's Association prevalence rates. Alzheimer's disease is the most common cause of dementia but not the only one, so this figure is not a full count of every dementia diagnosis in the city.
Why Wandering Is a Safety Concern
Wandering is a safety concern because a person with Alzheimer's disease or another dementia may leave home, become lost, and be unable to ask for help or find the way back. Restlessness, searching for a former home or job, or following an old daily routine can all lead to an unplanned exit. When 46,031 older adults in San Diego live alone, there may be no one in the house to notice a door opening in time.
A short walk can become an emergency near traffic, heat, or unfamiliar streets. Prevention focuses on supervision and the home environment, not on blaming the person who is confused. Families can review general information on Alzheimer's disease and related dementias from the Centers for Disease Control and Prevention.
Home Safety Steps That Reduce Wandering Risk
Home safety steps that reduce wandering risk include controlling easy exits, adding door alerts, keeping identification on the person, and lowering visual cues that suggest it is time to go out. These steps do not replace a person in the home when the risk is high, but they can buy time and make an unnoticed exit less likely.
Families often start with simple changes:
- Place door chimes or alarms that sound when an exterior door opens.
- Store car keys, coats, and purses out of sight if those items trigger leaving.
- Use locks that household members can still operate quickly in a fire or other emergency.
- Offer an ID bracelet or clothing labels with a name and emergency contact.
- Keep a recent photo and notes on usual walking routes ready if someone goes missing.
- Ask trusted neighbors to call if they see your loved one outside alone.
A regular daily routine, meals, and calm activity can also reduce the restlessness that sometimes leads to an exit. None of these steps is a medical treatment or a diagnosis. They are practical safety habits to use alongside supervision.
How In-Home Supervision Addresses Wandering
In-home supervision addresses wandering by keeping a caregiver on site who can see restlessness, intercept a move toward the door, and stay with the person through the day and night. Locks and cameras cannot redirect someone who is already outside, and they cannot calm fear or confusion in the moment.
Companion care provides presence, conversation, and activities during the hours when boredom or anxiety often leads to leaving. Memory care at home adds dementia-focused cueing and familiar routines that can reduce the urge to search for a past home or workplace. When wandering happens after dark or a spouse cannot stay awake, 24-hour live-in care keeps someone in the home overnight. Personal care with bathing, dressing, and toileting can also lower exits that start because someone is looking for a bathroom or clean clothes.
