paranoid elderly mother

Q: My mother is 80.  She is very active (despite breaking her hip 2 years ago), she still attends water therapy 3 times a week at the YMCA, she drives to the base (which is 20 miles away) and pays her bills on time.  She is a retired Psych nurse and has shown signs in the past of paranoia. 

Lately, she has “heard” voices of her grandchildren in her home and called my sister. She also has difficulty with getting the right words to say out and has her sleep pattern out of whack and will call people at odd times of the night.  With her independence comes the fact she won’t share any medical information because she thinks we are out to get her committed.  

How can I test her/question her to find out the level of decline she may be in to make sure she is safe? — K

A: Great question. As you may know, it’s fairly common for aging adults to develop problems like the ones you are describing. Some older adults will also start leveling a lot of false accusations. Understandably, these problems are frustrating and worrying for adult children.

You are absolutely right to be concerned about your mom’s safety. I do have some ideas for how you can get started assessing her, which I share below.

But first I want to explain the most common causes of this type of behavior in older adults. That’s because one of the things you must do is help your mother and the doctors figure out why she’s developed these behavior changes and other symptoms.

A fair number of people don’t get around to the medical evaluation because they assume that these crazy behaviors are either normal aging (definitely false) or dementia such as Alzheimer’s (true about 40% of the time).

Furthermore, it’s often hard to get a resistant older parent medically evaluated.

Still, it’s worth persisting in this, because many causes of paranoia or other odd behavior in older people can be treated.

Paranoia, false accusations and psychosis

Paranoid symptoms (e.g. believing that someone is out to get you, or is taking your stuff, or is in the house at night) falls into a category of mental symptoms that is technically called “psychosis.”

Symptoms of psychosis can include:

Psychosis is uncommon in younger people but becomes much more common as people get older. That’s because any of these symptoms can emerge when people’s brains aren’t working properly for some reason.

2015 review article on “late-life psychosis” estimates that 23% of people will develop symptoms of psychosis in late life.

6 causes of paranoia and psychosis in aging

In the above review article, the authors organize the causes of late-life psychosis into six “Ds”:

The authors of this review article also note that it’s common for older adults to have vision and hearing problems, both of which can trigger or worsen delusions and hallucinations.

So as you can see, when older adults experience delusions, hallucinations, and paranoid thoughts, there is almost always something more going on with their health. Figuring out what is beneath the “crazy” or “irrational” or “paranoid” behavior is key.

Hence, I recommend you keep these six causes of paranoid symptoms in mind, as you try to find out more about how your mom has been doing.

I also recommend you check for other signs of problems with thinking or memory; you can learn about 21 signs I recommend checking for in the video below.

How to check on “levels of decline” and safety

It’s great for you to be proactive and want to help check on your mother safety and situation. Ultimately you’ll need to work with professionals, but you can speed the process along by checking for common red flags, and bringing them to the attention of your mother’s doctor.

As a geriatrician, I generally try to assess an older person in the following five domains:

Because concerned family members often ask me about checking on an older parent, I’ve written a book, “When Your Aging Parent Needs Help,” that walks families through how to do this; it includes checklists based on the five sections above.

You can use the book and checklists to spot these red flags that often represent serious safety or health problems.

Now, no book is going to enable you to diagnose your parent. And no book can guarantee that you’ve identified and addressed the most important safety issues. You’ll need to work in person with professionals to do that.

But by being methodical in observing your mom and in documenting your observations, you will make it much easier for professionals to figure out why your mother has developed these behaviors you are concerned about.

Also, by identifying specific red flags or problem areas, you’ll be better equipped to work with your mom and other family members on addressing safety concerns. That’s because it’s much more effective to focus on issues that are specific and concrete (“I noticed that you seem to be having trouble with your grocery shopping”), rather than simply telling an aging parent that you are worried about their safety.

Tips on following up on safety issues and memory problems

Once you’ve identified safety issues and signs of underlying health problems, you’ll want to follow up. You’ll need health professionals to help evaluate and manage any underlying health problems, and you may find you need help from other types of experts as well.

If your older parent is paranoid and resisting your involvement, this often becomes a stuck spot for families.

How to get unstuck depends on the situation. Here are some ideas that often help:

When it comes to contacting the doctor and hiring an expert to help, it’s best if you can get your mom’s agreement before proceeding. (Or at least, not have her explicitly forbid you from doing these things). Here are some tips to help with your conversations:

For more on approaching a parent who is resistant to help, I explain how to do this in my free online training for families:

Now, if you find it causes your mother intense anxiety or agitation to discuss your concerns and your suggestions for helping her, it may be reasonable to just proceed. After all, you do have reasons to believe that some kind of health issue is affecting her thinking.

So especially if you’ve identified any safety problems, it’s reasonable to move ahead despite her preference that you not intervene.

In closing, I’ll reiterate that this is a very tough situation to navigate, and it usually takes time and persistence for families to make headway. Do try to take care of yourself as you work through this. Connecting with others facing similar challenges is a great way to get support and practical ideas on what to do next.

Good luck!
