The video is interesting but there are some flaws. First of all I have seen all sorts of claims stating different causes of Alzheimer's from plaques, tangling of the nerve fibers, calcification of the nerves, of course aluminum, etc. The fact is that nobody knows what really causes Alzheimer's. And part of the reason it is so difficult to determine the cause is that it cannot be diagnosd without an autopsy. So as long as the person is alive they technically should be diagnosed with senile demntia, not Alzheimer's. This also means that it is basically impossible to determine if a drug is really working for Alzheimer's since again the Alzheimer's diagnosis cannot be confirmed until after death.
