This is a great article, Dr. H. My mother had it, so I am particularly mindful of diet and exercise as well as supplements as you noted. I've been on several of them for the last ten years in particular. I just had my eyes checked and they are in superb shape. These adjustments make a huge difference. When it's in the family, we can be more susceptible. But just as with dementia, it's not a sentence. It's a suggestion, and we don' t have to take it as our destiny.
