By partnering with us, you’re joining the fight against Alzheimer’s disease in the Down syndrome community.
What is ABC-DS?
The Alzheimer Biomarkers Consortium-Down Syndrome (ABC-DS) is a 5-year research project where we follow a group of adult volunteers with Down syndrome to find signs and risks of Alzheimer’s. As part of the study, we gather data through brain scans, blood tests, and exams that look at how people with Down syndrome think.

What are Down Syndrome and Alzheimer’s Disease?
Down syndrome is a genetic condition caused by an extra copy of chromosome 21. It affects a person’s physical and intellectual development.
Alzheimer’s is the most common type of dementia that affects a person’s memory, thinking, and behavior. Alzheimer’s worsens over time, yet changes in the brain caused by Alzheimer’s happen many years before symptoms emerge.
Why study Alzheimer’s Disease in Down Syndrome?
Did you know that 70% of adults with Down syndrome will develop Alzheimer’s at some point in their life? Virtually all people with Down syndrome have brain changes consistent with Alzheimer’s by age 40. This needs to change. The only way to change these odds is to better understand, diagnose, treat, and prevent Alzheimer’s in the Down syndrome community.
