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

brain changes with aging 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 cognition 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 to Address Cardiovascular Risk Factors for Better Brain Health:
12 Risks to Know & 5 Things to Do

by Leslie Kernisan, MD MPH 96 Comments

cardiovascular risk factors A while back, I wrote an article on cerebral small vessel disease, a very common condition in which the small blood vessels of the brain develop signs of damage.

If you’re an older adult and you’ve had an MRI done of your brain, chances are pretty good that your scan showed signs of at least mild signs of this condition; one study of older adults aged 60-90 found that 95% of them showed signs of these changes.

These are basically like teensy strokes in the brain. Most are un-noticeable to people, but if you have enough of them, you can certainly develop symptoms, such as cognitive impairment, balance problems, or even vascular dementia.

To date, the cerebral small vessel disease article has generated over 100 comments and questions from readers. A common theme was this: “My MRI shows signs of this condition. What can I do?”

As I explain in the article and the comments, the first thing to do is to work closely with your doctors to understand what is the likely cause of the damage to the brain’s small blood vessels.

Now, when you do this, you may well find that your doctor just shrugs, or waves off the question.

That’s because in most people, cerebral small vessel disease is thought to be in large part a result of atherosclerosis (more on this term below) affecting the smaller arteries of the brain. And atherosclerosis affects just about everyone as they age, because it’s related to many basic cardiovascular risk factors that become very common in late-life.

So in many cases, asking the doctor why you have signs of cerebral small vessel disease may be like asking why you might have high blood pressure, or arthritis. These are common conditions and they are usually due to medically mundane causes and risk factors, including sub-optimal “lifestyle” behaviors and the general “wear and tear” on the body that is associated with aging.

(However, in some people, damage to the small vessels in the brain may be related to one or more particular medical conditions. Younger people, in particular, seem more likely to have a particular condition or risk factor that may be causing most of the damage.)

Whether you are younger (i.e under age 60) or older, always start by asking your doctors what they think are the most likely causes for any cerebral small vessel disease, and what they recommend you do to slow the progression.

And for most people, the main advice will be this: evaluate and address your cardiovascular risk factors.

“Vascular,” as you probably already know, means “blood vessels.” And blood vessels are critical to the function of every part of the body, because blood vessels are what brings oxygen and nutrients to every cell in the body. They also carry away waste products and toxins. So, blood vessel health is key to brain health.

This article will help you better understand how to address blood vessel health. Specifically, I’ll cover: [Read more…]

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 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? And how they can best help their parents with cognitive decline?

Well, they 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:

Small vessel ischemic disease
White matter disease
Periventricular white matter changes
Perivascular chronic ischemic white matter disease of aging
Chronic microvascular changes, chronic microvascular ischemic changes
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?
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.

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

by Leslie Kernisan, MD MPH 190 Comments

What should you do if an older person complains of 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 when your older relatives say they aren’t sleeping well, you’ll want to help them check 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.
