Brain scans reveal Age's role in Alzheimer's plaque buildup

This study used special brain scans (PET imaging) to measure amyloid plaques in 60 people with Alzheimer's disease or related conditions like posterior cortical atrophy and logopenic progressive aphasia. The goal was to understand how age influences the amount of amyloid in the brain. Participants also had memory tests, MRI scans, and some had a spinal tap to measure proteins. The study is complete and aimed at gathering knowledge, not testing a treatment.
