Unfortunately, I can't think of a solution to your problem. Of course, you could try to keep your brain in shape, but Alzheimer's is a serious illness and there's no way to cure yourself completely. You could write everything down on paper, but eventually you will forget about the paper notes.
At some point, you will have to give out your crypto savings to your airs and/or you will have to invest them in serious medical treatment.
People with Alzheimer's aren't capable of running their own finances. This sucks, but there's no way around. Really sad story, man.
AFAIK there is no solution or cure unfortunately and yes while its such a serious illness,
its more of an insidious one, a truly hateful one.
@PrivacyG - I'm sorry to hear about your illness, this and its cousin Dementia are two of
the only things that truly frighten me. I dont know anyone personally but know of friends
of friends who have been affected.
It seems that a common effect of the disease is for the patient to slowly regress back
to "childhood" - something you have eluded to yourself.
franky1 - fair play to him has been the first responder and hit on everything really.
Just to add something else, I think its important not to isolate yourself and get completely
wrapped up with exercising your brain, community has to play a part also, plenty of
interaction with others is important, get them playing games with you also.
I really wish you all the very best for the future.
