February 17, 2021 -- Imaging specialists who visually interpreted flortaucipir-PET images were able to determine a person's risk of progressing to Alzheimer's and mild cognitive impairment within the next 18 months in a recent study. Read More
PET scans show early link between heart disease, brain function
February 16, 2021 -- PET scans demonstrate that middle-aged individuals with early signs of cardiovascular disease also have reduced brain metabolism, according to researchers from Spain. The findings indicate that the early stages of Alzheimer's disease could begin years before dementia occurs. Read More
