You need to read my comment again.  I never stated nor think what you wrongly assume.<p>Your reasoning about the work of Dr Bredesen shows that you a re ignoring the facts.  reversal of Alzheimer in 9 of 10 patients is a very significant results since nobody has ever reversed Alzheimer.  The fact that the sample was small is only a reason to do a followup study with a larger number of patients, which is exactly what he is doing.<p>The desire to reduce protocols to only a single variable is based on the wrong assumption that treatments can be successful with only one variable changed and excludes all treatments where more variables play a role.
