“that needs to be reached in order to tip the balance toward APP’s anti-Alzheimer’s pathway. What this means is that you don’t have to address all thirty-six holes. When you have patched enough of them, the rest aren’t serious enough to let much water into your house. If we leave our roofing analogy to get back to Alzheimer’s, the presence of a few of the factors nudging APP down the Alzheimer’s-causing pathway isn’t enough to exert that nudge in enough of your brain neurons enough of the time to cause Alzheimer’s. Unfortunately, we don’t yet have a simple way to measure how many of the thirty-six each person can safely live with, and each hole is a different size for each person, depending on his/her genetics and biochemistry, so it’s best to address as many as you can until you see improvement. This is in fact what happens in the treatment of cardiovascular disease. When you address enough of the key pathophysiological parameters, like lowering your blood levels of triglycerides and reaching a healthy weight, you reverse cardiovascular disease, eliminating arterial plaque, as Dr. Dean Ornish has shown. Even if you do not patch all of the cardiovascular holes—maybe you still have an imperfect diet or some mild stress”
