9 Warning Signs Your Elderly Parent Shouldn’t Be Living Alone Anymore

Updated: Oct. 07, 2022

Moving aging parents to a living arrangement that offers care and support is difficult, but sometimes it's the only way to keep them safe and healthy.

Keep an eye out for these issues

Aging can be difficult, but it’s particularly challenging when the person who is aging is a parent. Over time, life-long relationships can be upended and the parent—who has presumably spent a lifetime caring for a child—becomes the one who needs help. However, crossing that boundary is tricky and exposes all kinds of feelings and emotions for both the parent and adult child. Older people may want to stay in their home and maintain their independence, and that’s completely understandable. An adult child may not want to fight with a parent who’s determined to live on their own. But there may come a time when a living arrangement needs to change for a parent’s safety and welfare. Role reversal is difficult to navigate and it might be a challenge to know exactly when and how much help an elderly parent needs. Keep an eye out for these warning signs that an older parent or relative probably shouldn’t be living alone anymore.

They’ve suddenly lost weight

If you notice your parent is looking thinner than usual, it may be a sign that they’re not eating well, which could be a sign of the beginning of a cognitive illness. Lisa Gwyther, director of Duke University’s Family Support Program, explains that people suffering from memory impairment, such as Alzheimer’s disease, often either forget to eat certain meals or forget how to properly manage and cook their food, causing them to lose weight. If this is the case, you might want to discuss the possibility of having a home aide to make sure they receive adequate nutrition each day. You may also consider moving your loved one into your home, if that’s possible, or to an assisted living facility.  (Here’s how to talk to your aging parents about their health.)

Towering heaps of unopened mail can be another clear indication of growing cognitive impairment. Gwyther says to keep a close eye out for unopened envelopes from creditors or charities your parents wouldn’t normally donate to. This can be a red flag that they’ve lost control of their judgment when it comes to smart spending, which can drive them into debt rapidly if it goes unnoticed. Ask your parents these questions to keep them safe and healthy.

They’re ignoring their personal hygiene

For someone with dementia or Alzheimer’s, remembering all of the cognitive steps involved with taking a shower every day can be challenging. It may be difficult for them to understand why they need to take a shower and how to do it, leaving them with an unhealthy hygiene routine. “‘You can tell them that it looks like they need a shower, but they just don’t see it,” Gwyther says.

They get lost when going to familiar places

Common destinations like the grocery store, the bank, or their place of worship should be familiar and easy to remember for your parent. If you find they can no longer find their way to these destinations, it’s a big red flag that something is wrong. Gwyther explains that if you can no longer trust your loved one’s ability to navigate their own town, it might be time to discuss moving or having live-in help for safety’s sake.

You notice changes in their home

A cluttered house isn’t necessarily a bad sign if your parent was always a bit messy, explains Peter Lichtenberg, PhD, director of the Institute of Gerontology and Merrill Palmer Skillman Institute. However, if they suddenly begin letting order slide after a lifetime of cleanliness, it might be a sign of an underlying cognitive issue. Additionally, watch out for items showing up in strange places around the home, like a gallon of milk in the dishwasher instead of the refrigerator. According to Dr. Lichtenberg, changes like these are often some of the clearest signs of dementia, and they could be a clue that your loved one is no longer in a position where it’s safe for them to be home alone.

Their Internet habits have shifted

For those with Internet-savvy parents, be on the lookout for any strange or unusual new online habits, as this could signal dementia or another similar illness. “People who are cognitively declining are at a real risk of ordering things they don’t need, taking on debt, and facing identity theft,” Gwyther says. “Even if they had been on the Internet and had been perfectly fine before, families need to be looking out for that.” You should also take a look at their Facebook or other social media accounts from time to time to make sure they aren’t accidentally befriending people who could be potentially dangerous. Gwyther explains that this is a common issue for people with cognitive disorders, as it’s hard for them to tell who’s a friend and who’s a foe. (Here’s what people with Alzheimer’s wish you knew.)

They’re always exhausted

Dementia, Alzheimer’s disease, and other chronic conditions can disrupt circadian rhythms, keeping your loved one up all night and drowsy all day. As Gwyther explains, sleep is absolutely vital for both cognitive and physical functioning, and missing out on much-needed z’s can make a person’s condition even more serious. (Or a health condition could be the reason they aren’t sleeping.) If it seems like your parent’s lack of sleep is putting a significant crimp in their well-being, you may consider more supervision or help. Your parent may also benefit from seeing a geriatric psychiatrist who can help manage sleep issues. If cognitive impairment isn’t to blame, this might be why your parent is tired all the time.

They have a strange collection of new medications

If your parent’s medicine cabinet is suddenly filled with unusual or possibly unnecessary medications, a cognitive impairment could be the explanation. Gwyther explains that many patients with diseases like dementia or Alzheimer’s disease often accidentally misuse over-the-counter medications, as they’re trying to treat something that isn’t really the problem. She also says to make sure your parent is taking the medications they do need, and that they’re taking them at the appropriate times. If month-old bottles of their daily medication are sitting around completely full, it might be because they no longer can remember to take them.

They’re defensive

As extreme is it might seem, Gwyther says there have been many instances of aging people in cognitive decline purchasing guns to keep in their home for protection, even if they never owned a gun previously. With a disease like dementia, people can become combative or suspicious of those around them—including family—as they can’t distinguish who’s trying to help and who’s trying to hurt them. Having a gun in the house (or other weapon) can be incredibly dangerous for someone who’s cognitively impaired, so flag it as a sign that they should no longer be living alone. (Here’s why you should stop believing these myths about Alzheimer’s disease.)

How do you start the conversation?

Bringing up the possibility of having a home aide or moving your parent into a nursing home or assisted living facility can be difficult. Dr. Lichtenberg says to approach the topic delicately by asking your parent how they’re feeling and what their goals are, and asking whether or not they’ve noticed any changes in their behavior. From there, you can introduce the idea of getting help, explaining that it’s a smart first step to achieving those goals. People with declining cognition often can’t understand that something is wrong, so it’s important to take it slow and account for their perspective. Take the time to get educated about the three most common forms of dementia, so you can attempt to understand what your parent is going through.
