8 Behaviors to Take Note of if You Think Someone Might Have Alzheimer’s

by Leslie Kernisan, MD MPH 27 Comments

Have you been worried about an older person’s memory or thinking skills? If so, you’ve probably found yourself wondering if this could be Alzheimer’s, or another dementia.

What to do next? If you look online or ask people, the advice is generally this: tell the doctor.

This advice isn’t wrong, but it’s incomplete. Yes, you should tell the doctor. But you’ll dramatically improve your chances of getting to the bottom of things if you come to the doctor with useful information on what you’ve observed.

In fact, research has found that interviewing family members about the presence or absence of eight particular behaviors can be just as effective, when it comes to detecting possible Alzheimer’s, as certain office-based cognitive tests.

Flu Shots for Older Adults: What to Know & Do for 2026

by Leslie Kernisan, MD MPH

It’s that time of the year: fall, which I think of as flu vaccination time.

This is especially important given that during the past two winters, influenza was pretty bad and caused more deaths than COVID did.

I always think getting a flu vaccine is a good idea for most older adults. So I agree with the Centers for Disease Control (CDC), which is urging that people get vaccinated against influenza early in the fall (before the end of October 2026).

I cover the new mRNA flu vaccine and more 2026 updates for flu vaccines (and COVID vaccines) in this video:

Now, vaccination against seasonal influenza can seem like 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 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 stronger flu vaccines that are now recommended for older adults, plus what to know about the new mRNA flu vaccine for adults aged 50+.

This year, I agree with the CDC that it’s important for people to get their seasonal flu shot, and if you are an older adult, I recommend getting one of the four flu vaccines specifically recommended for older adults. (See below for more on these!)

Note: If you are age 65 or older — or otherwise at high risk — you may be able to get your fall COVID vaccine at the same time.

The Centers for Disease Control (CDC) estimates that every year, influenza affects 9.4-51 million Americans, causes 120,000-710,100 hospitalizations, and results in 6,300-52,000 deaths. In most years, influenza vaccination does help reduce hospitalizations and deaths (I go into details below).

So this year, it’s important to do what you can to reduce respiratory illness, to protect yourself, and to protect others. And getting vaccinated against influenza is one of the things we can do.

In fact, I’m about to go get mine. As a healthy woman who has recently turned 50, 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 & the CDC’s recommendations specifically for older adults
What’s new and resources for the 2026-2027 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
Whether it’s more important to get a flu shot or a COVID vaccination (or a booster)

Medications Older Adults Should Avoid or Use with Caution:
The American Geriatrics Society Beers Criteria

by Leslie Kernisan, MD MPH

Today we’re covering a touchstone resource for geriatricians: the “Beers List” of medications that older adults should avoid or use with caution.

(Technically, it’s called “The AGS Beers Criteria® for Potentially Inappropriate Medication Use in Older Adults.” I personally think of it as the list of “risky medications” for older adults.)

If you want to know which medications older adults should be careful about, this is the list!

This list gets updated every few years, so the Beers Criteria published in May 2023 is about as up-to-date as you can get for this type of guideline document.

The AGS (American Geriatrics Society) also in July 2025 published a really useful related resource on alternatives to Beers Criteria medications.

You should know that experts in geriatrics and in medication safety go through a very careful process of reviewing the research on medications, and of updating this list of medications that older adults should avoid or use with caution.

So in this article, here’s what I’ll be sharing with you:

A Trial of ICU Care: a true end-of-life story

by Leslie Kernisan, MD MPH

In another post, I’ve shared the story of Mrs. F, a very ill older woman with cancer who said she didn’t want to go to the hospital, even though she wasn’t on hospice.

Now, I want to share another true story, about a nonagenarian with cancer. He was DNR and we had planned for comfort care once his symptoms got worse. But when he fell dangerously ill, I ended up advocating for him to go to the Intensive Care Unit. Below is the story, with tips for caregivers at the end.

5 Top Causes of Sleep Problems in Aging, & Proven Ways to Treat Insomnia

by Leslie Kernisan, MD MPH

What should you do if an older person complains of insomnia, or is not sleeping well at night?

Experts do believe that “normal aging” brings on some changes to sleep. (See this post for more on how sleep changes with aging.) Basically, older adults tend to get sleepy earlier in the evening, and tend to sleep less deeply than when they were younger.

So it’s probably not realistic to expect that as you get older, you’ll sleep as long or as soundly as when you were younger.

That said, although aging by itself does change sleep, it’s also quite common for older adults to develop health problems that can cause sleep disturbances. So if you’re older and aren’t sleeping well, you’ll want to make sure you’ve been checked for these. Figuring out what’s going on is always the first step in being able to improve things.

And remember, getting enough good quality sleep helps maintain brain health, physical health, and mood.

In this article, I’ll cover the top causes of sleep problems in older adults. I’ll also tell you about what approaches have been proven to work, to help treat insomnia and sleep problems in older adults.

Last but not least, if you (or your older relative) have experienced the very common combination of waking up to pee at night and difficulty sleeping, I highly recommend listening to this podcast episode, which features a geriatrician who is an expert on this: 092- Interview: Addressing Nighttime Urination & Insomnia in Aging.

Slow Heart Rate in Older Adults: Bradycardia, Pacemakers & What to Know

by Leslie Kernisan, MD MPH

Have you ever been told that your heart rate is slow, or maybe too slow?

This is called bradycardia, and it’s fairly common in older adults. Whereas in younger adults, a slow heart rate is often due to being in good cardiovascular shape, with aging, a slower heart rate often reflects changes in the heart’s electrical system. (Medications are another common cause.)

This can be an issue because a slower heart rate can cause symptoms such as fatigue, dizziness, falls, or trouble keeping up with usual activities.

Fortunately, in certain situations, a pacemaker can be an effective treatment that helps older adults feel substantially better.

To help older adults learn more about bradycardia and when to consider a pacemaker, I interviewed cardiologist Cara Pellegrini, MD, who specializes in cardiac electrophysiology. Here’s what’s most important to know, based on our conversation.

7 Steps to Managing Difficult Dementia Behaviors
(Safely & Without Medications)

by Paula Spencer Scott

(This article is by my colleague Paula Spencer Scott, author of the book Surviving Alzheimer’s: Practical Tips and Soul-Saving Wisdom for Caregivers. I invited her to share an article on this topic, since many in our community are coping with dementia behaviors. — Dr. K)

The odd behaviors of Alzheimer’s and other dementias can be so frustrating and stressful for families.

I’m talking about the kinds of behaviors that try patience, fray relationships, and drive us in desperate search of help:

“First she thinks the caregiver is stealing her sunglasses and now she accused me of having an affair.”

“When I tried to help Dad wash up, he hit me.”

“My husband follows me so closely I can’t stand it. But if I go in another room he’ll wander out of the house.”

“Mom started unbuttoning her shirt in the middle of the restaurant!”

“Just when I’m completely exhausted at the end of the day, he seems to get revved up. He keeps peeking out the windows, convinced that someone is trying to break in. Now he won’t sleep.”

A common approach to sundowning and difficult behaviors is to go right to medicating them with tranquilizers, sedatives, or antipsychotics. But that’s risky and often not what’s best.

In fact, experts recommend trying behavior management first, and for good reasons: It tends to be more effective in the long run than “chemical restraints,” has no dangerous side effects, and leads to a better care relationship. But people often don’t know how to do this.

I’ve learned how.

I’ve lived through five close family members’ experiences with Alzheimer’s and other forms of dementia. Lots of trial and error, and insights from dozens of top dementia experts (whose brains I’ve been lucky to pick as a journalist and dementia educator), got me through regular scenes with…

My father-in-law, who needed a walker to move yet spent hour after hour for several days straight hauling all his clothes and toiletries from his room to our driveway, insisting that his (imaginary) new wife was about to pick him up
My dad, a formerly sharp dresser who wore the same shirt and pants every day no matter how dirty
My grandmother, who insisted on going “home,” when she was home
And other relatives, in dozens of similar scenes.

In this article, I want to share what I wish someone had explained to me early on: the “Why-This, Try-This” approach to dealing with difficult behaviors.

This is a mental framework that can help you get unstuck from unproductive responses that get you nowhere or make things worse.

It can bring calm -– to both of you — whether the issue is verbal or physical aggression, agitation, confusion, wandering, disinhibition, delusions, hallucinations, or a restless or repetitive behavior (like pacing, shadowing, rummaging). It also works well with milder irritants like repetitive questions and indecision.

Then, I’ll boil down the Why-This, Try-This concept to a 7-step process you can use every time. These “7 R”s give you a basic platform for responding to any frustrating behavior:

6 Common Medication Problems in Aging, & What You Can Do

by Leslie Kernisan, MD MPH

Yesterday, August 21, was National Senior Citizens Day, a good opportunity to recognize older adults and reflect on what supports healthier aging. Medication safety is an important part of that, since the benefits, risks, and burdens of medications can change as we get older.

If you’re helping an older person with health and healthcare, chances are that person is taking at least a few prescription medications, if not several.

Do you ever wonder if he or she is on the right medications? Do you worry about side-effects and interactions?

These are sensible concerns to have. Many older adults end up experiencing “polypharmacy,” which means taking more than 5 medications concurrently.

And although medications do often help maintain health and wellbeing, studies have repeatedly shown that lots of older adults end up suffering from problems related to medication.

Polypharmacy, predictably, increases the risk of problems. (Polypharmacy is usually defined as taking five or more medications concurrently.) But even older adults taking one to three daily medications can encounter problems.

So I want to share a list of common ways that medications affect the health and wellbeing of aging adults. I’ll then explain what you can do, to minimize these problems.

Addressing Medical, Legal, & Financial Advance Care Planning:
The Healthy Aging Checklist Part 6

by Leslie Kernisan, MD MPH

This is the sixth and final post covering the Healthy Aging Checklist, a set of six core activities that will help any older adult maintain the best possible health while aging.

They are:

Promote brain health and emotional well-being.
Promote physical health.
Check for and address common aging health problems (such as falls, memory concerns, depression, incontinence, pain, isolation, polypharmacy).
Learn to optimize the management of any chronic conditions.
Get recommended preventive health services for older adults.
Address medical, legal, and financial advance care planning.

In this post, I’ll address the last item on the list: advance planning for medical, legal, and financial issues. This includes power of attorney documents, plus much more.

This is a big topic, and it’s not possible to cover everything you could or should do in a single article. You would need a book for that — I suggest three down below — plus it’s best to work with qualified professionals (healthcare providers, eldercare attorneys, and financial planners) before completing any legally binding paperwork.

But every day as I work, I see older adults and families whose health and well-being is being affected by the consequences of their planning — or lack of planning, as the case often is.

So in this post, I will share some practical information that should make it easier for you to address planning that covers some common age-related challenges:

The three key steps involved in all advance planning for aging
5 common problems every older adult and family should consider planning for
5 key steps for advanced planning in healthcare, and where to get a good free medical power of attorney (POA)
4 key steps for advance planning for legal and financial issues, and what to know about general POAs
Tips for adult children, including what to do if you’re concerned about mental capacity or undue influence

27 Recommended Preventive Health Services for Older Adults: the Healthy Aging Checklist Part 5

by Leslie Kernisan, MD MPH

This is the fifth in a series of posts covering the Healthy Aging Checklist, which is my list of six fundamental activities that will help any older adult maintain the best possible health while aging.

They are:

Promote brain health and emotional well-being.
Promote physical health.
Check for and address common aging health problems (such as falls, memory concerns, depression, incontinence, pain, isolation, polypharmacy).
Learn to optimize the management of any chronic conditions.
Get recommended preventive health services for older adults.
Address medical, legal, and financial advance care planning.

In this post, I’ll cover recommended preventive health screening guidelines and other prevention services for older adults. These are based on the recommendations of the U.S. Preventive Services Task Force (USPSTF) and also on Medicare’s coverage of preventive health services.

By my count, based on the USPSTF and Medicare guidelines, there are currently 27 preventive health services that older adults should consider. I have a summary list here, and then detailed information on each service starting here.

Get Your Free Preventive Health Cheatsheet! The 27 proven preventive health services for older adults, in a handy PDF checklist that you can print or save. Includes details on who should get each service, and helpful links. Click here now.

But before you read about them, let’s go over the basics of how health screening and other preventive health services work, including why they can sometimes be harmful, or sometimes fall out of favor.

This way, when you review the list of preventive services to consider, you’ll better understand which services are likely to help, and why certain services may not be a good fit for you or your parent.
