6-CN-PiB binding in the frontal cortex of DS and control cases. 6-CN-PiB binding was not observed in A. a 19-year old control case, B. a 19.8-year old DS case and, C. a 51-year old middle aged control case. In contrast, D. shows abundant 6-CN-PiB binding in plaques (arrowheads) and in CAA (arrows) in a 51.4 year old person with DS. Bar = 300 μm.
