PET imaging in Alzheimer's disease

What is it about?

Recent (and multiple previous) international publications claim that positron emission tomography (PET) imaging of amyloid depositions in the brain helps diagnosing Alzheimer's disease (AD). However, this claim is unjustified and an example of circular reasoning, since cerebral amyloid is not synonymous with AD and because there exists no infallible reference with regard to presence or absence of AD.

Why is it important?

Because this erroneous claim helps cementing and keeping alive an unhealthy, self-sufficient scientific culture based on a falsely positive image of a significant research that in reality causes anxiety among patients and elderly citizens and misleads authorities and pharma companies to invest interest and billions of dollars in a closed circuit that helps doctors and companies involved instead of afflicted patients and society. It is time to break the illusion and start all over again.
