Brain changes associated with Alzheimer’s may begin at least seven years before amyloid plaques become detectable with current PET scans. Researchers uncovered the signal by tracking healthy older adults with repeated brain imaging over nearly 20 years. The discovery could help scientists identify Alzheimer’s earlier and suggests that important disease processes may start before visible plaque buildup.
Alzheimer’s Brain Changes Detected Years Before Plaques Appear
Researchers found that brain changes linked to Alzheimer’s can occur at least seven years before amyloid plaques are detectable, based on a 20-year study of healthy older adults. This discovery could lead to earlier identification of Alzheimer’s. While the article does not directly relate to Iran, advancements in medical research could impact healthcare policies in the country.
