Cognitive Impairment in Aging: 10 Common Causes & 10 Things the Doctor Should Check

Have you been worried about an older person’s memory or thinking abilities?

Maybe your parent has seemed more confused recently. Or you may have noticed that your aging spouse is repeating herself, or struggling to do things that didn’t use to pose much of a problem.

These are very common concerns, and they often lead to questions such as:

Is this normal aging or something more significant?
What is wrong?
Could this be Alzheimer’s? Or some other form of dementia?
Can this be treated or reversed?
What should we do about this??

The answer to the last question is this: if you are worried about memory or thinking, then you should seek out some kind of medical evaluation.

That’s because when families worry about an older person’s cognitive abilities, there often are some underlying health issues affecting the mind’s function.

Those need to be detected, and treated if at all possible. So, you’ll need to request help from a health professional, and in this article, I’ll explain what that initial help should consist of. This way you’ll know what to expect, and what the doctor might ask you about.

Technically, these kinds of problems are called “cognitive impairment.” This is a broad term that means some kind of problem or difficulty with one’s memory, thinking, concentration, and other functions of the conscious brain, beyond what might be expected due to normal “cognitive aging.”

(For more on “cognitive aging” and what types of changes are considered normal aging, see this article: 6 Ways that Memory & Thinking Change with Normal Aging, & What to Do About This.)

Cognitive impairment — which is also called “cognitive decline” — can come on suddenly or gradually, and can be temporary or more permanent. It may or may not keep getting slowly worse; it all depends on the underlying cause or causes.

In this article, I’ll share with you the more common causes of cognitive impairment in older adults.

I’ll then share a list of 10 things that should generally be done, during a preliminary medical evaluation for cognitive decline in an older adult.

Anemia in the Older Adult:
10 Common Causes & What to Ask

by Leslie Kernisan, MD MPH

Have you ever been told that an older relative has anemia?

Or perhaps you noticed the red blood cell count flagged as “low” in the bloodwork report? Or noticed “low hemoglobin” in a doctor’s report?

Anemia means having a red blood cell count that is lower than normal, and it’s very common in older adults. About 10% of independently living people over age 65 have anemia. And anemia becomes even more common as people get older.

But many older adults and families hardly understand anemia.

This isn’t surprising: anemia is associated with a dizzying array of underlying health conditions, and can represent anything from a life-threatening emergency to a mild chronic problem that barely makes the primary care doctor blink.

Still, it worries me that older adults and families don’t know more about anemia. If you or your relative has this condition, it’s important to understand what’s going on and what the follow-up plan is. (I’ve so often discovered that a patient didn’t know he or she had had anemia!) Misunderstanding anemia can also lead to unnecessary worrying, or perhaps even inappropriate treatment with iron supplements.

And since anemia is often caused by some other problem in the body, not understanding anemia often means that people don’t understand something else that is important regarding their health.

Fortunately, you don’t have to be a doctor to have a decent understanding of the basics of anemia.

This post will help you understand:

How anemia is detected and diagnosed in aging adults.
Symptoms of anemia.
The most common causes of anemia, and tests often used to check for them.
What to ask the doctor.
How to get better follow-up, if you or your relative is diagnosed with anemia.

How to Prevent Falls: 4 Proven Approaches To Ask Your Doctor About

by Leslie Kernisan, MD MPH 28 Comments

elderly woman falling Worried about falls in an older parent or relative? If so, do you know if their doctor has considered the most useful prevention approaches?

Fall risk can be reduced, but it generally takes some thought and effort. That’s in part because most older adults have multiple factors making them vulnerable to falls.

In a related article on this site, I’ve explained that best fall prevention plans involve identifying an older person’s particular risks — especially risks related to health conditions — and trying to counter those.

Get Your Free Fall Prevention Resource Guide! A handy short PDF to help you quickly find the key online resources mentioned in this article. Click here to download.

So for instance, if an older person has diabetes and is having frequent moments of low blood sugar (also known as hypoglycemia), then to reduce falls, addressing the hypoglycemia is as important, if not more, as starting an exercise program.

In other words, I always recommend that aging adults and families learn to tailor their fall prevention plans. You want to focus on what are the most important modifiable risk factors for that individual person.

That said, over the years I’ve noticed that there are four approaches that I find myself using over and over again, in almost all my patients who have had repeated falls.

These four approaches are used often by geriatricians, but much less often by busy primary care doctors. Unless, that is, a proactive family asks about them.

Flu Shots for Older Adults During COVID Times: What to Know & Do for 2020

by Leslie Kernisan, MD MPH 136 Comments

Usually, I update this article in October, which I think of as flu vaccination time.

But this is 2020 and things are different, so I am writing this in September. In particular, due to COVID-19, the Centers for Disease Control (CDC) is urging that people get vaccinated against influenza early in the fall (before the end of October 2020).

Vaccination against seasonal influenza has always been a bit of a tricky topic. Many older adults are skeptical of the need to get a yearly vaccination against influenza. They aren’t sure it will help. Or they think that the vaccination will actually give them a mild case of the flu. Or they just don’t like needles.

Or maybe they aren’t sure which type of seasonal flu shot to get: the regular one or one of the newer “stronger” versions, designed for older adults?

And now that we have COVID-19 to contend with, vaccination for seasonal influenza might feel even more confusing for people.

Don’t let yourself be confused. In this article, I will share with you what I know about influenza vaccination and what I’ve learned about influenza in COVID times. I also have updates on the newest high-dose vaccines available for older adults.

But let me share the bottom line with you right now. In general, I have always supported the CDC’s usual recommendation that everyone over the age of 6 months should get their seasonal flu shot.

This year, I agree with the CDC that it’s especially important for people to get their seasonal flu shot, as soon as you can, and if you are an older adult, I recommend getting one of the higher-dose vaccines.

In “normal” pre-COVID times, the Centers for Disease Control (CDC) estimates that every year, influenza affects 9-45 million Americans, causes 140,000-810,100 hospitalizations, and results in 12,000-61,000 deaths. In most years, influenza vaccination does help reduce hospitalizations and deaths (I go into details below).

And now this fall, we will also have COVID-19 to contend with. As of September 2020, at least 190,000 Americans have died of this disease. We don’t know for sure what will happen this fall, but since COVID seems to spread more when people are indoors and in proximity to the exhalations of others, COVID is likely to get worse this fall.

So this year, more than ever, it’s important to do what you can to reduce respiratory illness, to protect yourself, and to protect others. We don’t yet have a COVID vaccine, but we do have influenza vaccines.

In fact, I’m about to go get mine. As a healthy woman in her 40s, I’m not that concerned about getting dangerously ill from influenza. Instead, I get my annual flu shot because I want to minimize my chance of getting sick and perhaps exposing my older patients to influenza.

Here’s what I’ll cover in this article:

The basics of influenza and vaccination against the flu
What we know about influenza and COVID-19
What to know about flu shots for older adults
What’s new and resources for the 2020-2021 flu season
Which influenza vaccination is probably best for most older adults
What to do if your older parent or relative is unwilling or unable to get vaccinated
