There is a critical need to identify measures of cognitive functioning sensitive to early Alzheimer’s disease (AD) pathophysiology in Down syndrome to advance clinical trial research in this at-risk population. The objective of the study was to longitudinally track performance on cognitive measures in relation to neocortical and striatal amyloid beta (Aβ) in non-demented Down syndrome.
New NIH-funded initiative will examine Alzheimer’s disease in people with Down syndrome

We have seen a profound increase in lifespan for individuals with Down syndrome (DS) in the past few decades leading to a large and somewhat understudied population of middle- and older aged adults with DS. One health condition consistently seen in clinic-based DS samples is dementia (including Alzheimer’s disease).
