Brain Imaging Links Alzheimer's Decline to Tau Protein (IMAGE)
Caption
Images across the top show compilations of PET brain scans of people who are cognitively normal. Images across the bottom show compilations of PET brain scans of patients with symptoms of mild Alzheimer's disease. The difference between scans of healthy people and scans of patients with mild Alzheimer's disease is much more apparent in the images that measure tau (right four images), suggesting tau protein buildup in the brain is a better marker of Alzheimer's disease symptoms than the long-studied amyloid beta buildup (left four images).
