As you can read here, Dale Bredesen, MD, has discovered a way to not only stop the progression of Alzheimer's, but to reverse it. People on his protocol actually improve on their cognitive scores.
Bredesen's protocol uses blood tests to pinpoint what's causing the Alzheimer's. It could be inflammation, a nutritional deficiency, insulin insensitivity, a toxic overload, a vascular problem, a head trauma, or a combination of these.
Once the problem has been identified, steps can be taken to solve it, and the brain begins to recover.
But even before any testing is done, there's quite a bit you can do to move toward recovery on your own. Bredesen has identified seven categories of improvements that make a real difference in your cognitive performance. The categories are:
Nutrition
Exercise
Sleep
Stress reduction
Brain stimulation
Detoxification
Supplementation
You can do many of these things on your own, and most of them won't cost you a dime. You can read more about these here: The Bredesen Seven.
