Deans' stroke musings: Is Adult Education A Brain Shield Against Dementia?

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Is Adult Education A Brain Shield Against Dementia?

Further research needed before you can do this on your own.

Is Adult Education A Brain Shield Against Dementia?

Summary: Researchers unveiled a promising link between adult education and reduced dementia risk. The study analyzed data from the UK Biobank, finding that individuals involved in adult education courses had a 19% decreased chance of developing dementia.

The protective effect wasn’t solely linked to underlying conditions like cardiovascular diseases or mental illness. More rigorous trials are needed to confirm these results.

Key Facts:

Individuals attending adult education classes had a 19% lower risk of developing dementia.
The research analyzed data from 282,421 UK Biobank participants aged between 40 and 69.
Though the study revealed protective effects of adult education on fluid intelligence and nonverbal reasoning, it didn’t show effects on visuospatial memory or reaction time.

How can we best keep our brain fit as we grow older? It’s well known that regular cognitive activity, for example brainteasers, sudokus, or certain video games in middle and old age tends to protect against cognitive decline and dementias like Alzheimer’s.

But many of us regularly engage in adult education classes, for example learning a language or a new skill. Is such adult education likewise associated with a lower risk of cognitive decline and dementia?

Yes, according to researchers from the Institute of Development, Aging and Cancer of Tohoku University in Sendai, Japan who have shown for the first time, in a new study in Frontiers in Aging Neuroscience.

“Here we show that people who take adult education classes have a lower risk of developing dementia five years later,” said Dr Hikaru Takeuchi, the study’s first author. “Adult education is likewise associated with better preservation of nonverbal reasoning with increasing age.”

UK Biobank

Takeuchi and his co-author, Dr Ryuta Kawashima, a professor at the same institute, analyzed data from the UK Biobank, which holds genetic, health, and medical information from approximately half a million British volunteers, of which 282,421 participants were analyzed for this study.

These had been enrolled between 2006 and 2010, when between 40 and 69 years old. On average, they had been followed for seven years by the time of the present study.

Based on their genotype at 133 relevant single-locus polymorphisms (SNPs) in their DNA, participants were given an individual predictive ‘polygenic risk score’ for dementia. Participants self-reported if they took any adult education classes, without specifying the frequency, subject, or academic level.

The authors focused on data from the enrollment visit and third assessment visit, between 2014 and 2018. At those visits, participants were given a battery of psychological and cognitive tests, for example for fluid intelligence, visuospatial memory, and reaction time.

1.1% of participants in the sample developed dementia over the study’s time window.

Reduced risk of developing dementia

Takeuchi and Kawashima showed that participants who were taking part in adult education at enrollment had 19% lower risk of developing dementia than participants who did not. This held true for both Caucasian people and those of other ethnicities.

Importantly, results were similar when participants with a history of diabetes, hyperlipidemia, cardiovascular diseases, cancer, or mental illness were excluded. This means that the observed lower risk wasn’t exclusively due participants with incipient dementia being prevented from following adult education by symptoms of these known co-morbidities.

The results also showed that participants who took part in adult education classes kept up their fluid intelligence and nonverbal reasoning performance better than peers who did not. However, adult education didn’t affect the preservation of visuospatial memory or reaction time.

Randomized clinical trials necessary

“One possibility is that engaging in intellectual activities has positive results on the nervous system, which in turn may prevent dementia. But ours is an observational longitudinal study, so if a direct causal relationship exists between adult education and a lower risk of dementia, it could be in either direction,” said Kawashima.

Takeuchi proposed that a randomized clinical trial be done to prove any protective effect of adult education.

“This could take the form of a controlled trial where one group of participants is encouraged to participate in an adult education class, while the other is encouraged to participate in a control intervention with equivalent social interaction, but without education,“ said Takeuchi.
