Aging, Your Brain, and Memories

brain

I've also said that as we learn more and more, we may lose earlier memories or change those memories to fit in with the newer information that is arriving!

I've been known to say that as we age, of course we may alter or forget stuff - because our brains have years and years of memories to sort through, filter, and recall...

And so it did not surprise me at all to see this recent research which has shown that:

Recalling a particular memory can cause us to forget another, similar memory - and neuroscientists have now watched this process happen using brain scans.
folders

I like to think of the brain like a file cabinet drawer or shelf, or even a folder such as you might have on your computer. In your file cabinet drawer you have manila folders - usually the 3 cut ones with the tabs on top which you label for certain papers. If you have a lot of folders that are for different but related material, you might have these within a larger folder - the kind with hooks on the side that you can slide backwards and forwards in the drawer. How many of the larger sliding folders and how many of the smaller manila folders that you have is really up to you and your particular filing system.

​But. And it's a big but. The drawer is only so many feet, if not inches, long. There is a limit to the number of larger and smaller folders that you can push into that drawer before it gets jammed. What you do at that point is sort of what your brain does. It has to make space somehow for newer material. You can move a whole batch of those folders to another drawer. You can look through them and say I don't need these anymore and either shred them or toss them.

That's what we do in our brains. Maybe the stuff is never lost but it's been put in a drawer that is seldom used because you just don't need those memories or that information anymore. Maybe it's still there and under some degree of hypnosis or thinking or whenever you can bring it back but if it's really now irrelevant to your life - why not just forget it.....​

Skirts, Waist Sizes, and Breast Cancer?

belly fat

I've lectured groups about belly fat and why it is "bad" and here is yet more "proof" that collecting that fat in your middle is not-too-good!

Recent research shows an easy way to let you know if your belly fat poses a risk for you as you age.

How? Remembering if your skirt size has gone up in the last few decades!

The study tracked more than 90,000 women in their 50s and 60s living in England.

During the three-year follow-up period, 1,090 women developed breast cancer.

The researchers found that a unit increase in UK skirt size every 10 years (for example from 12 to 14) between 25 and post-menopausal age was linked to a 33% increased risk of breast cancer.

Going up two skirt sizes in the same period was associated with a 77% greater risk, they report.

Much of our belly fat accumulation is lifestyle related and it can be reduced by good nutrition, exercise, and simple lifestyle changes.

And knowing that you need larger skirts every year may indicate that you do need a change!

And maybe next we need to study men and pant sizes to see if there is a correlation with some adverse health outcome for them?

Sleeping Pills and Alzheimers

pills may harm you

If you read this blog, you know I am not a fan of
big pharma and pill pushing!

Too many people, especially older people, are prescribed drugs that they may not need, or that may mix badly with others drugs they are prescribed.

​Correlation studies are not about causation - they only indicate that things "seem" related. In this study, the relation was between pills for anxiety and an increase in the risk of developing Alzheimer's disease.

Long-term use of pills for anxiety and sleep problems may be linked to Alzheimer's, research suggests.

A study of older Canadian adults found that past benzodiazepine use for three months or more was linked to an increased risk (up to 51%) of dementia.

I am not anti-medications for medical issues where they are needed, but I have known too many people over 65 being prescribed pills for too many issues that might have other solutions. 

We are too pill happy and
too often see medication
as the answer to a problem.

Lack Of Vitamin D and Dementia?

sunshine
Older people who have a severe vitamin D deficiency have an increased risk of developing dementia, a study has suggested.

In looking at more than 1600 people older than 65, and for 6 years, the researchers found:

All were free from dementia, cardiovascular disease and stroke at the start of the study.

At the end of the study they found the 1,169 with good levels of vitamin D had a one in 10 chance of developing dementia. Seventy were severely deficient - and they had around a one in five risk of dementia.

More research needs to be done, and done looking at the differences between Vitamin D supplements or getting more sunshine by being outside.

And if looking at supplements, making sure they are not synthetics;
but real food!


For me, it's another example that simple things like eating well, getting outside, or exercising can reduce the risk of dementia....

Getting Your Sweat On: In Shorts Bursts!

Get your sweat on!

Some research in Scotland, with only a few participants, showed that high intensity training [6 second bursts of going "all out"] may be very beneficial.

Over the 6 week study, they increased the burst to 1 minute and the researchers found this HIT exercising lowered blood pressure and made regular life tasks like dog walking easier for the participants.

More research is needed with more people, but it does seem to be saying that:

Getting your sweat on, in short bursts,
is good for you at any age!

"...you're never too old, too frail, too ill to benefit from exercise, as long as it's carefully chosen."

"We know even into your 80s and 90s there's a benefit from developing a very slight sweat by exercising on multiple occasions per week."

So? What are you waiting for?

Me? I'm taking woof for some short burst training.

Have you tried this? How did it help? Or not?
