A now-seminal study published in 2006 provided evidence that the toxic accumulation of a protein called beta-amyloid in the brain was tied to the development of Alzheimer’s disease. Recently, an assistant professor from Vanderbilt University suggested that some of the images in this study were manipulated by the authors. What does all of this mean?

In 2006, a group of researchers from the University of Minnesota published a dementia-related study titled in the journal NatureTcalled “A specific amyloid-β [beta-amyloid] protein assembly in the brain impairs memory.” The study provides evidence supporting a specific protein clump in the brain, known as beta-amyloid, as a cause for Alzheimer’s disease.

The study used a mouse model to show how these protein clumps — also known as amyloid plaques— could cause dementia.

Because of its findings, this study became very influential in Alzheimer’s disease research. To date, it has been cited in over 2,200 scientific papers and accessed more than 34,000 times.

Now an article recently published in Science reports that an assistant professor of neurology at Vanderbilt University believes some of the images were manipulated in the 2006 Nature study, calling into question the validity of its findings.

Dr Martenson synthesizes the findings in this recent video:

AFAIR, many times reading and listening to different people talking about the topic I paid attention about wording accuracy regarding amyloid, it seems not even because of the fraud expectation but because of "immanent" scientific research problems surrounding the topic many people just do not take the amyloid hypothesis as a strong thing
