Chronic Pain Linked to Memory Loss in Some Older Adults

By Pat Anson, PNN Editor

A new study suggests that people who live with chronic pain may be at higher risk of memory loss and cognitive decline if they have lower levels of education, income and access to healthcare.

The study by researchers at the University of Florida, published in the Journal of Alzheimer’s Disease, involved 147 adults between the ages of 45 and 85 who had mild to moderate knee pain. Participants enrolled in the study were asked to provide sociodemographic information, complete an assessment of their cognitive function, and have MRI brain scans.

People with higher pain levels who had low levels of income and education, and less access to health insurance had about 4% less gray matter in the temporal lobe of their brains (the area shaded in blue) compared to people with low pain levels who had more income and education, and greater access to healthcare.

“As we get older, typically starting around our mid-50s to mid-60s, we lose about half a percent of our gray matter per year,” said lead author Jared Tanner, PhD, an assistant professor of clinical and health psychology in the UF College of Public Health and Health Professions. “So a 3-4% difference could be thought of as an additional six to eight years of aging in the brain.”

The thinning of gray matter is predictive of future cognitive decline and greater risk of developing dementia or Alzheimer’s disease.

Tanner and his colleagues have been investigating how chronic pain acts as a stressor that causes physiological changes in humans. Other researchers have found that Black adults are up to twice as likely as White adults to develop Alzheimer’s disease. The new findings indicate a variety of environmental factors might be involved, including access to healthcare.

“This study helps us begin to identify an additional factor to explore that may contribute to health disparities in rates of dementia and Alzheimer’s disease in some underrepresented ethnic/race groups. In this case, it looks like stage of chronic pain, along with other life experiences, may be playing a role,” said Tanner.

“The body and the brain are adaptive to stress to a certain point,” said senior author Kimberly Sibille, PhD, an associate professor of aging & geriatric research and pain medicine in the UF College of Medicine. “But with persistent stressors that are more intense and longer duration, eventually the body’s response is no longer adaptive and changes start occurring in the other direction, a process known as allostatic overload. 

“People with low pain stage — intermittent, low intensity, shorter duration and minimal sites of pain — differ from the groups with higher stages of chronic pain. Further, in combination with lower protective factors, including lower income, education and health insurance access, those individuals with higher chronic pain stage show less gray matter in cortical areas of the brain.”

A large 2017 study found that people aged 60 and older with chronic pain had faster declines in memory and cognitive ability than those who were not troubled by pain.

The brain may be able to regain some of its ability to function normally. A 2009 study of osteoarthritis patients showed a reversal in brain changes when their pain was adequately treated. 

Pain Companion: Losing Your Smarts to Pain

By Sarah Anne Shockley, Columnist

In my last column, When Pain Hijacks Your Brain, we looked at a couple of ways that living with chronic pain affects cognitive ability; specifically, blank spaces and brain freeze.

This month we’ll look at memory loss and overall loss of brain power, and share some tips I’ve learned about mitigating their impact.

What to Do About Memory Loss            

Can’t remember what you did yesterday or even two minutes ago? Short-term memory loss is common for people in pain. I believe it is because the body and brain are simply overloaded having to deal with compromised health, and the overall stress and exhaustion that pain creates in the system.                   

Sure, forgetting things happens to everyone. But for those of us living with chronic pain, it seems to happen more often and it takes longer for our brains to come back online.                 

Write yourself notes and stick them everywhere. Write the note immediately or you will forget not only what was supposed to go on the note, but that you were writing a note at all. (No kidding)                               

I keep the smallest size of Post-it Notes in my car and stick notes on the dashboard so I don’t forget where I’m supposed to be later or what I need to do when I get home. I leave these little pads all over the house with pens nearby.                   

I have Post-its all over my computer, my desk and my kitchen, and I just throw them out when I’m finished with them. I have gotten into the habit of writing EVERYTHING down the minute it comes into my head and sticking it immediately where I will find it later.                   

What about the problem of walking over to the Post-it pad and forgetting what you’re supposed to write there on the way? (You’re only laughing because something similar has happened to you, I’m sure!)

Go back to the physical spot where you were when the thought came to you and put yourself in the exact same position and wait a moment. Somehow, the body and brain sort of coordinate in resetting yourself back in time, and then your brain often sends you the same message again.                   

Oh, and don’t forget to have the Post-its and pen already in hand.        

What to Do About Loss of Brain Power                   

My brain in pain can barely make sense of how to balance my bank accounts. Truly. It scares me to look at a row of numbers. Not because numbers are scary to me or I’m terrible at math – I aced all my graduate finance and economics courses – it scares me because, when in pain, I can’t make heads or tails of them. It’s like looking at Egyptian hieroglyphs.                   

It is incredibly disconcerting to lose your smarts to pain. Focusing on anything becomes nearly impossible. I remember having a vocational aptitude test done after I was injured and not being able to read a high school level paragraph or answer the questions appropriately.

I sat there and reread the same three-sentence paragraph about four times and simply couldn’t make any sense of what they were asking me to do with it. If you’ve had an experience like this, you know how frightening it can be to realize you just don’t have access to your normal cognitive functioning. It’s like someone turned the lights off upstairs.

Your brain in pain is simply not firing on all cylinders or most of its energy is going to dealing with the pain you’re in and healing your body. There just isn’t much brainpower available to you for normal cognitive processes.                   

This was true for me during the most acute part of my pain and it went on for quite some time. Thankfully, I have been able to recover much more access to my cognitive processes since then. So, please know that if you are going through the worst of this kind of side effect right now, it can get better as you move out of the most acute pain. You can get your brain back.             

For the purpose of regaining a modicum of brainpower, and for using some of my unused mental energy, I started doing extremely easy Sudoku puzzles, a popular Japanese number game.                   

At first, doing Sudoku worked like a sleeping pill because I quickly wore my brain out just trying to make sense of the very easiest puzzles and basically knocked myself out. I kept at it as a nightly sleep aid and eventually I was able to complete the easy puzzles. I usually had to erase what I’d already filled in and start over about 3 or 4 times in order to finish one small puzzle.                

I found that, in addition to acting like a benign sleeping pill, Sudoku helped bring my brain back online over time. I was able to progress from Easy to Medium to Hard. (I have not graduated to the Evil level yet.)

This tells me that even if the brain is hijacked by pain, it is possible to bring it back by starting small. Simple crossword puzzles can work too, but initially I found that even these were too demanding and frustrating. I could come up with a number from 1 to 10 more easily than a specific word.      

There are other ways to bring the brain back online as well: Scrabble, Monopoly, cribbage, backgammon or any other game requiring some counting, but are not overwhelmingly complex.

Jigsaw puzzles, origami, scrapbooks, photo collections; anything that requires organizing visually can also be useful. If you have enough mental energy for it, small amounts of foreign language study can also do the trick. Many public library systems have easy and free courses you can use online.

These ideas seem really simple, I know, but that’s exactly where to start. Really easy and really simple.

Pain Companion: When Pain Hijacks Your Brain

By Sarah Anne Shockley, Columnist

I had a great inspiration for this article a couple of weeks ago and immediately forgot what it was. I exhausted myself, uselessly racking my brain for the idea I’d had. What was it I thought was so perfect to write for Pain News Network?

Several days went by with me trying to find the elusive idea. I couldn’t even figure out what it related to. It was as if it had completely left the universe and was utterly irretrievable. Gone without a trace.

Ever feel like that?

Studies have shown that chronic pain affects the brain, but most of us living with chronic pain don’t need researchers to tell us that. We live with brains that don’t seem to be firing on all cylinders every day. I don’t know if there is an official term for it, so I’m just calling it “Pain Brain.”

In this and my next column, I’ll discuss some of the ways in which Pain Brain affects our ability to cogitate -- and some practical ways I’ve found to live with it a little more gracefully and even to coax the brain back online.

Dealing with Blank Spaces        

Do you find yourself in the middle of a sentence and can’t remember what you were talking about? Sometimes can’t come up with the words for even the most common items like chair, book, pen? 

We worry that we might be getting Alzheimer’s and sometimes find ourselves very embarrassed when, in the midst of telling someone something important, our brains simply turn off.

We’re left with our mouths hanging open in mid-sentence, whatever we were just talking about an utter mystery to us. We draw a complete blank. Sometimes it’s just a word, but often it’s the whole concept. Just gone. This can be extremely disconcerting.                                    

I find, particularly when I’m tired, that I’m creating sentences with a whole lot of blank spaces in them. “Can you hand me the... the... the... the... you know, I mean, uh... the… the... the.....” You’ve probably done this too.            

Stop. Breathe. Relax. Laugh. Choose another word. Or just let it go and carry on without that word or even that idea. It’s not that your brain is dying, you’re in pain.            

I’ve found that it’s usually not all that helpful to exert a lot of energy to try and recapture the word I lost. I’ve found that my efforts usually don’t make a bit of difference. I can’t conjure up that exact word or thought no matter how hard I try - and I just wear myself out and get flustered.                   

Pushing your brain to get back into gear creates tension, and you don’t need any more of that. Trying to find the exact word leaves a longer silence in your conversation, and you get the deer-in-the-headlights look, and that’s when you begin to feel uncomfortable and embarrassed. You want to say, I’m not really stupid or senile or easily distracted, I used to be able to converse with the best of them!                   

Instead, just move on with the conversation. Usually, sooner or later, the words you need pop back in. Sometimes much later. Sometimes in the middle of the night. But that’s okay. If we can just be easy with it, it’s not that big of a deal. It’s usually more disconcerting for us than the person we’re talking with.

Dealing with Brain Freeze

There are times, however, when it’s more than a particular word that’s missing. For me, it’s often a total brain freeze. Everything comes to a screeching halt, usually in mid-sentence. I have no idea what I was just saying, what the topic of the conversation was, or what direction I was headed in.                  

It’s pretty strange, because you don’t lose the power of speech, you just have no idea what you’re talking about anymore. It’s like the part of your brain dealing with that specific subject goes on a coffee break in the middle of a sentence, leaving you kind of stunned by its complete lack of presence.

For friends and family members, you can make up a code word or phrase for when you’re feeling disconnected from your own brain. I often just say, Sorry, my brain just stopped. It’s short and to the point, and they’ve learned what it means. They either remind me of what we were talking about, or we move onto something else.                   

For other people who don’t know your situation, and if you find yourself embarrassed by your own stupefaction, you might try just changing the topic. It’s really strange, but the brain seems to be able to go somewhere else and work relatively well, just not where you wanted it to go at the moment.

You can also distract other people’s attention from your sudden silence by asking them a direct question such as, What were you saying a moment ago? Or simply, What do you think? If they have something they have to respond to, it usually diverts their attention from your blank stare.

If you refer to what they were saying indirectly, without having to remember exactly what it was they actually said, they will often fill in the blanks for you and help you back on track -- without you having to explain that your brain just stopped.

Living with Pain Brain can be challenging, but in my experience, those of us who struggle with it notice the blank spaces and lost words much more than anyone we’re conversing with.    

In my next column, we’ll talk about memory loss and lowered capacity to cogitate. I’ll have some suggestions for working with them as well.
