I got the Shingles vaccine a little while ago and it's starting to look like a very good decision. Large studies repeatedly show it reduces dementia and now it's even linked to reduce cardiovascular disease. If you can get it, definitely do it.
Alzheimer's disease does not necessarily equal dementia. people can have Alzheimer's disease and not get dementia. So, we found this out from post-mortem studies. People have been followed as they age. Uh they've donated their brains and it turns out that perhaps 20 to 30% of these individuals who never had dementia have Alzheimer pathology.
Those include that having that sense of purpose, making sure that you have a network of people, that you're socially connected as your age, and also remaining curious, open to new ideas. Those factors turn out to be almost as important as some of the physical things we do.
And there was no food or you know olive oil or food group or you eating more or less meat that changed the relationship between the Mediterranean diet and dementia risk. So what that tells me is it's much more about whole foods.
we've gotten to a point now where it's generally accepted that potentially half of cases of dementia are preventable and I think the majority of that falls into those first two buckets Alzheimer's and vascular dementia
They just published a secondary analysis of the active trial that showed that um those who did processing speed training with uh booster sessions at one and three years had a significantly decreased risk of dementia 20 years later.
but I mean in reality when you look at the data on sleep loss and dementia risk The cut off is really around 6 hours. So if you're consistently sleeping fewer than 6 hours, that's where risk starts to increase.
And I think, you know, most people when they talk about aging, they're so worried about dementia and, you know, Alzheimer's disease as a specific form, but balance is even more important, I think. And most people aren't even aware of their balance.
and you found that these nuns, how they aged, some of them certainly when they passed away, their brains had these kind of hallmark signs of dementia, plaques and tangles, but behaviorally they were still high functioning. So, it's really interesting that the hardware shows what we see as dementia and specifically Alzheimer's disease, but their behavior uh was that of a fairly healthy cognitive person.
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com.
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.
About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
