The amyloid hypothesis, as described to me by someone working in the field, is not only wrong, but it is harmful to the patients. His research is studying that it is more probable that the plaques are actually protective and do not cause the memory loss and other disease symptoms directly. This idea was pushed aside and ridiculed for years all because of the greed and lies by people like Eliezer Masliah.
