It’s hard to imagine someone as young as eight coming down with Alzheimer’s. And yet in people with Down Syndrome, symptoms of dementia can set in at a very early age. Turns out Down Syndrom and Alzheimer’s have some things in common genetically. That led researchers at the University of Colorado School of Medicine to test an Alzheimer’s drug on a small sample of patients with Down syndrome. The results are encouraging. Dr. Alberto Costa led the study and tells Ryan Warner about a patient whose memory improved dramatically.
