First it would be good to know if you have genetic predisposition. I think mosts comercial DNA tests available test for APOE4 variations.

Second I would read on the research of Dr. Dale Bredesen. He has been studying how to map all the underlying factors that can lead to Alzheimer and how to test/treat markers that are associated with the disease.

According to him Alzheimer's disease is like a roof full of holes. You need to test and treat each individual hole to make sure it's not leaking.

This is good advice. Be aware that while APOE variants are the most well known and common causes of a genetic predisposition to Alzheimer’s, there are several others, including some 100% penetrance, dominant gene mutations that cause it. Unfortunately I have very significant experience with one of these. Generally it would be common enough in your family (roughly 50% of people getting it), that you’d have reason to suspect one of these gene mutations.

Even if Dr Bredesen is misdiagnosing the causes of Alzheimer's, his recommendations are still just the basics of healthy living. Like exercise, getting enough sleep, good dental hygiene, etc.
