this is very powerful.

But you are on to the answer in that final paragraph. And no, sorry that I don't mean the bible and prayer, although I have nothing against them. I mean by stimulating the mind continuously, you can fight back.

Genetics is only 5% of the results that you see. The rest is down to a thing called epigenetics.
Basically it's not the genes, but how they express themselves, and that gives us great power.
Look into it and you will see how you can be proactive. Don't give the chance for the undesired thing to manifest itself, through lifestyle choices and conscious actions.
I'm wouldn't be the best person to explain it to you, but very sympathetic to your situation. I am only a few years older, and I see the changes in my brain too.

And they are scary.

Almost enough to make me consider lifestyle changes, and conscious choice of action.

if you wanna talk about it, I'm here. And there.
