Cerebral Small Vessel Disease:
What to Know & What to Do

by Leslie Kernisan, MD MPH

Signs of cerebral small vessel disease. From Inzitari et al, BMJ. 2009 Jul 6;339:b2477. doi: 10.1136/bmj.b2477

This article is about the most common aging brain problem that you may have never heard of.

While leading a fall prevention workshop a few years ago, I mentioned that an older person’s walking and balance problems might well be related to the presence of “small vessel ischemic changes” in the brain, which are very common in aging adults. (This is also called “white matter disease.”)

This led to an immediate flurry of follow-up questions. What exactly are these changes, people wanted to know. Do they happen to every older adult? Is this the same as vascular dementia? And how they can best help their parents with cognitive decline?

Well, these types of brain lesions don’t happen to every older person, but they do happen to the vast majority of them. In fact, one study of older adults aged 60-90 found that 95% of them showed signs of these changes on brain MRI.

In other words, if your older parent ever gets an MRI of the head, he or she will probably show some signs of these changes.

So this is a condition that older adults and families should know about. Furthermore, these changes have been associated with problems of consequence to older adults, including:

Cognitive decline,
Problems with walking or balance,
Strokes,
Vascular dementia.

Now, perhaps the best technical term for what I’m referring to is “cerebral small vessel disease.” But many other synonyms are used by the medical community — especially in radiology reports. They include:

White matter disease
Small vessel ischemic disease
Brain lesions
Periventricular white matter changes
Perivascular chronic ischemic white matter disease of aging
Chronic microvascular changes, chronic microvascular ischemic changes
Chronic microvascular ischemia
White matter hyperintensities
Age-related white matter changes
Leukoaraiosis

In this post, I will explain what all older adults and their families should know about this extremely common condition related to the brain health of older adults.

In particular, I’ll address the following frequently asked questions:

What is cerebral small vessel disease (SVD)?
What are the symptoms of cerebral SVD?
How is cerebral small vessel disease related to vascular dementia and cerebrovascular accidents?
What causes cerebral SVD?
How can cerebral SVD be treated or prevented?
Should you request an MRI if you’re concerned about cerebral SVD?

I will also address what you can do, if you are concerned about cerebral SVD for yourself or an older loved one.

Q&A: What You Can Do if You’re Worried About “Incompetence”

by Leslie Kernisan, MD MPH

Q: My 87-year-old father lives alone. His house has become increasingly dirty, but he refuses to get help, even though I’m sure he needs it. I’m worried that he’s becoming incompetent and in need of elder care, but he doesn’t want to go see the doctor. What can I do?

A: This situation does come up a fair bit with aging parents and relatives. I’m sorry to say there usually are no easy solutions. But there definitely are things you can and should do, and it’s better to act sooner rather than later.

Let’s review what you can do. I’ll also explain what I’ve learned about “incompetence” over the years, and how doctors usually play a role in the evaluation of such older adults.

Then, I’ll share some thoughts on how older people and families can plan ahead, to avoid facing this kind of dilemma. And then last but not least, I share a few thoughts on taking care of yourself as you go through this.

The usual concern, for a person of this age, is that the person may have developed memory loss, or a dementia such as Alzheimer’s disease.

This is a pretty reasonable worry, since an estimated 30% of people aged 85+ have dementia. (Wondering about dementia vs Alzheimer’s? Here’s where I explain dementia and how it’s related to Alzheimer’s.)

And of course, if your older parent seems to be doing worse than before, when it comes to activities that require mental organization (such as keeping a house reasonably clean), that further increases the chance that some kind of brain deterioration is causing problems.

But, we should never start by jumping to the conclusion that someone has developed dementia and needs elder care.

How to Evaluate, Prevent & Manage Constipation in Aging

by Leslie Kernisan, MD MPH

Constipation is not a glamorous topic, but it’s certainly important, especially in older adults.

As anyone who has experienced occasional — or even chronic — constipation can tell you, it can really put a damper on quality of life and well-being.

Constipation can also cause more substantial problems, such as:

Severe abdominal pain, which can lead to emergency room visits
Hemorrhoids, which can bleed or be painful
Increased irritability, agitation, or even aggression, in people with Alzheimer’s disease or other forms of dementia
Stress and/or pain that can contribute to delirium (a state of new or worse confusion that often happens when older adults are hospitalized)
Fecal incontinence, which can be caused or worsened by having a hard lump of stool lodged in the lower bowel
Avoidance of needed pain medication, due to fear of constipation
Worsening of urinary leaks

Fortunately, it’s usually possible to help older adults effectively manage and prevent constipation. This helps maintain well-being and quality of life, and can also improve difficult behaviors related to dementia.

The trouble is that constipation is often either overlooked or sub-optimally managed by busy healthcare providers who aren’t trained in geriatrics. They are often focused on more “serious” health issues. Also, since many laxatives are available over-the-counter (OTC), some providers may assume that people will treat themselves if necessary.

Personally, I don’t like this hands-off approach to constipation. Although several useful laxatives, such as polyethylene glycol (brand name Miralax) are indeed available OTC, I’ve found that the average person doesn’t know enough to correctly choose among them.

Also, although in geriatrics we often do end up recommending or prescribing laxatives, it’s vital to start by figuring out what is likely to be causing — or worsening — an older person’s constipation.

For instance, many medications can make constipation worse, so we usually make an attempt to identify and perhaps deprescribe those.

In short, if you’re an older adult, or if you’re helping an older loved one with health issues, it’s worthwhile to learn the basics of how constipation should be evaluated and managed. This way, you’ll be better equipped to get help from your health providers, and if it seems advisable, choose among OTC laxative options.

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

Providing Elder Care: Covering the Cost of Home Care, Assisted Living & Other Options

by Leslie Kernisan, MD MPH

aging woman with caregiver One of the most common questions I get asked is “How can I get care for my aging parent and how much will it cost?”

The answer generally depends on these factors:

What kind of elder care does the older person need or want?
What are the available options for providing the needed elder care?
How much do the different options cost?
What are the options for paying for the desired type of elder care?

These are important questions to consider. If your aging parent seems to need help, it’s imperative to find out what are your options for providing the needed support. And finances do often determine how a family proceeds with arranging elder care.

And even if your aging parent doesn’t need help now, they very well might in the future. So it’s also reasonable to plan ahead, and consider how elder care might be provided, if/when it becomes needed in the future.

Now, the truth is that most older adults don’t need much assistance from others. But research shows about 70% of older adults do end up needing some form of “senior care,” for a time ranging from a few months to several years.

So in this article, I’ll share the key things to know, about options for elder care and how to pay for it. Specifically, I’ll cover: [Read more…]

Is Your Aging Parent OK?
What to check & how to talk about it

by Leslie Kernisan, MD MPH

Have you been getting worried about your aging parent, or wondering if they are ok continuing to live as they are?

Maybe they’ve been mostly okay but now you’re spotting some problems with memory, such as forgetfulness or asking the same questions repeatedly. Or maybe you’ve noticed trouble with driving, keeping up the house, managing stairs, or paying bills.

Some aging parents simply begin to seem more withdrawn. Others start leveling accusations at others, claiming someone took or moved something, or acting paranoid.

When families notice these types of changes, it’s often really hard to know what to do next. How do you know if they really need help or not, and what kind of help to get? And what do you do if they refuse to discuss it, or get mad when you bring it up?

Since this is such a common dilemma for families, I’ve recorded a video, explaining exactly what you can do, if you’ve noticed some worrisome changes in your parent and are trying to figure out what to do next. Here’s how to know if your aging parent needs help, and how to talk to them about your concerns.

9 Great Gift Ideas for Older Adults & Family Caregivers

by Leslie Kernisan, MD MPH

It’s getting to be that time of the year: the season when many of us start looking for a thoughtful gift to give to an older loved one.

I’ll be honest: I’m not much of a shopper and it’s not my style to give physical gifts just for the sake of doing so.

But I do think it can be wonderful to give something that brightens a person’s day.

And it’s even better when a gift is practical, useful, or otherwise helps an older person make the best out of life.

In this article, I’ll share my list of eight gifts that can help older adults cope with common late-life challenges.

Four are for older adults in general, and then four are especially useful for those living with Alzheimer’s or a related dementia.

6 Ways that Memory & Thinking Change with Normal Aging (& What to Do About This)

by Leslie Kernisan, MD MPH

It’s annoying but unfortunately true: most parts of the body work less well as one gets older and older.

This is even true of the brain, which is part of why it becomes more common to experience a “tip of the tongue” moment as one gets older.

Such age-related changes in how the brain manages memory, thinking, and other mental processes are called “cognitive aging.”

Understanding how aging changes cognitive function is important. It can help you understand what to anticipate when it comes to your own aging. It can also help families better understand the changes they’re noticing in an older person, and whether those are out of the ordinary or not.

Since I’ve often written about changes in thinking that are abnormal and concerning in older adults, I thought it might be helpful for me to write an article outlining what is normal and to be expected.

Specifically, I’ll cover:

How cognitive aging differs from other diseases and conditions that affect memory and thinking
6 ways that memory and thinking change with aging
The difference between crystallized and fluid intelligence
How to tell cognitive aging apart from more worrisome changes, such as mild cognitive impairment and signs of Alzheimer’s and related dementia

Vitamin D: What to Know
(& Why to Be Careful About High Doses)

by Leslie Kernisan, MD MPH

Confused by all the back and forth in the media about vitamin D?

That’s understandable. Once touted as the thing to take for health and well-being, vitamin D has actually not been meeting expectations in randomized trials. It’s even been demoted in some expert recommendations.

That said, there is still a pretty easy and straightforward approach that most older adults can take.

In this post, I’ll explain what I recommend to most of my older patients, and why it’s important to be careful about taking higher doses of vitamin D3.

I’ll also address the following vitamin D frequently asked questions:

How much vitamin D to take every day?
What does vitamin D do?
What to know about the symptoms of vitamin D deficiency
The benefits and side effects of vitamin D
Which type of Vitamin D should I take?
Do I need to have my vitamin D blood level checked?
What should one’s vitamin D level be?
Will vitamin D really prevent falls or fractures?
Will vitamin D prevent dementia, cancer, and/or premature death?
I am outside a lot. Do I need a vitamin D supplement?
I heard that a higher level of vitamin D is better for you. How much is too much?

You can also learn more about the surprising risks of too much vitamin D in aging in this video:

Now, when I first wrote this article in 2015, vitamin D supplementation for older adults was recommended by experts — to help reduce the risk of falls and fractures, among other things — although most geriatrics experts did not think the high doses (e.g. 2000 IU daily or more) that many people take are indicated.

(For years now, many people have had unrealistic expectations of what vitamin D can do for them. Sometimes this is because they think it will improve their health. In other cases, it seems to be because their doctors never got around to reducing a higher dose which should’ve only been used for a limited time period. Either way, it’s concerning because taking high doses of vitamin D has been linked to problems, as I explain below.)

Today, experts in geriatrics are reassessing what to recommend for vitamin D supplementation.

This reassessment is in large part driven by the publication of a large randomized trial of vitamin D supplementation in older adults, the VITAL study, plus a few other research studies that have suggested that higher doses of vitamin D supplementation are associated with more falls and hospitalizations.

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

by Leslie Kernisan, MD MPH

Have you ever been told that you have anemia, or wondered about anemia symptoms?

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 We Diagnose Dementia: The Practical Basics to Know

by Leslie Kernisan, MD MPH

“Doctor, do you diagnose dementia? Because I need someone who can diagnose dementia.”

A man asked me this question recently. He explained that his 86 year-old father, who lived in the Bay Area, had recently been widowed. Since then the father had sold his long-time home rather quickly, and was hardly returning his son’s calls.

The son wanted to know if I could make a housecall. Specifically, he wanted to know if his father has dementia, such as Alzheimer’s disease.

This is a reasonable concern to have, given the circumstances.

However, it’s not very likely that I — or any clinician — will be able to definitely diagnose dementia based a single in-person visit.

But I get this kind of request fairly frequently. So in this post I want to share what I often find myself explaining to families: the basics of clinical dementia diagnosis, what kind of information I’ll need to obtain, and how long the process can take.

Now, note that this post is not about the comprehensive approach used in multi-disciplinary memory clinics. Those clinics have extra time and staff, and are designed to provide an extra-detailed evaluation. This is especially useful for unusual cases, such as cognitive problems in people who are relatively young.

Instead, in this post I’ll be describing the pragmatic approach that I use in my clinical practice. It is adapted to real-world constraints, meaning it can be used in a primary care setting. (Although like many aspects of geriatrics, it’s challenging to fit this into a 15 minute visit.)

Does this older person have dementia, such as Alzheimer’s disease? To understand how I go about answering the question, let’s start by reviewing the basics of what it means to have dementia.

5 Key Features of Dementia

A person having dementia means that all five of the following statements are true:
