Your risk of dementia: Do lifestyle and genetics matter?

This article was confusing and discouraging.
If I understand it correctly having a healthy life style might make only a small difference in preventing dementia. But I read elsewhere that both the mediteranean diet and the mind diet may reduce the risk of alzheimers by 50%. h
After reading “Do lifestyle and Genetics Matter?” I’ve come to a conclusion. We may become demented or we may not. I will however continue with what in my opinion is a healthy diet and lifestyle.
With all due respect, once again Harvard fails to see the forest for the trees. So far the big players, Harvard, Alzheimer’s Association, Mass General, etc. are sticking so strictly to their “gold standard” for what passes as acceptable research and possible conclusions, that a disease with a dire, devastating prognosis, that is ravaging people, and the families that care for them, has done NOTHING to help anyone. How much money and time has to be down the drain before Harvard entertains the idea that THEY need to approach this disease differently than their usual protocol? Not only has there been zero progress in treating, much less curing Alzheimer’s, the lack of any progress is going to cause investors to decide to invest their money elsewhere. Maybe, given the complete failure of Harvard and friends to do anything to help anyone, it is time to loosen up your strict research protocols and think outside of the box. So sick of getting e-mails that basically offer nothing new or hopeful. Some of the “lesser” powers in medicine are at least trying new, less conventional approaches to figuring this disease out. Harvard, get over yourselves and your very conservative, only we know how to conduct research, loftiness and help the terrible suffering and devastation of real people. Alzheimer’s is clearly not going to fall in line with you and your traditional way of research.
Now 65, I have been a dedicated vegetarian since the age of 21.
Health was NEVER the motive. It was and remains a determined ethic, out of covenant with my fellow creature Spirits.
At the age of 18, I had a Tubal Ligation, during my last year of high school. There was NO LOVING way to otherwise prevent Huntington’s in my genes, which could NOT be empirically determined.
At least some 50 individuals in this extended family, have now either died or or will succumb to its horrors. I made the right decision and nothing would have stopped me. How ANYONE would KNOWINGLY subject their OWN children to this HELL and not DO ANYTHING to STOP it from manifesting, is BEYOND reality…..INEXCUSABLE.
NO symptoms have demonstrated, except for some balance issues. I have a strong hunch, that DIET has contributed significantly to delaying onset.
After the genetic world was forEVER altered in the early 90’s, NO ONE should REFUSE DNA testing and foreknowledge in the face of these ABSOLUTE realities. It COULD have and SHOULD have ENDED the NIGHTMARES in ONE generation.
Factors such as social interactions and educational ( informal and from different sources) stimulation most likely play a role in this too.
A.D. the most common cause of Dementia caused by pathology of Beta Amyloid plaques tangling be researched as to how to prevent that pathology will ultimately be the answer to prevent & or treat A. D.
Healthy diet and healthy life style are required to prevent HTN & stroke. And thereby hopefully may prevent another but smaller % of A.D.
Genomic research ultimately leading to vaccine to prevent A. D. In geneticsayb predisposed individuals. US current study underway is enthusiastically awaited.

From Dr. Patel’s piece:
“The lifestyle score was associated with dementia risk. Second, the genetic score was also associated with dementia. In other words, individuals with worse scores were at higher risk for dementia. The researchers further found that genetic risk and lifestyle appeared to act independently of each other. For example, individuals with both an unhealthy lifestyle and a high genetic risk score had almost two and a half times more risk than individuals with a low genetic score and healthy lifestyle.”
I find this paragraph puzzling. The final sentence reads as if it contradicted the previous one, or at least doesn’t build on it. The argument here may be clear to an expert bringing extensive background to the area, but it isn’t to this general public member.
My wife has been diagnosed with vascular demensia. Would vitamin k2help in any way?
how is pollution a modifiable “lifestyle” factor if the US gov’t is rolling back Clean Air regulations? And if you’re scrambling to pay your rent or mortgage already? It’s not like it’s a secret that poorer parts of the US or urban areas are the most polluted. Nice to put the burden on those who have great difficulty getting by rather then the local, state & federal gov’ts whose “leaders” think income inequality and more pollution (so businesses can increase their profits by laying off costs:–such as controlling toxic/polluting discharges) is just fine–as long as it’s not in their “backyards” or in the “backyards” of their most generous supporters.
Clean air isn’t being rolled back any farther than what the standards were in 2008. And if you know ANYTHING about air standards, you’d know that highly efficient cars produce much, much higher levels of NOx pollution that is exceptionally irritating to people with asthma or other sensitivities. That’s the MAIN SOURCE of pollution that most people are constantly exposed to and will continue to be exposed to until electric cars are a practical form of transportation for almost all regular commuters.
