How much better it would be if instead of worrying about a cure, we would do what it takes to prevent the disease. A great many factors go into it, about which I've written lately, and a HUGE amount of it is squarely in our hands regarding diet, exercise, brain exercises and attitude. THAT is more important that looking for a cure after too many years of abusing our bodies. While I feel deeply for those who have it or whose families care for one who does, the rest of us can do a great deal to prevent it even if we have the gene. Therein lies the greater answer: prevention in the first place.
