Scientists use brain scans to track Alzheimer's-Linked protein in older adults

This study uses a special PET scan to measure tau protein buildup in the brains of 106 older adults, some with normal aging and some with mild cognitive impairment (MCI). The goal is to understand how tau relates to memory and brain structure changes, which could help tell apart normal aging from early Alzheimer's disease. Participants must be 60 or older and part of a larger long-term study.
