Over the last 15 years, scientists have made enormous strides in understanding how Alzheimer’s disease affects the brain. Many of these recent insights point toward promising new strategies for treatment, prevention and diagnosis.
Following successful laboratory work or animal studies, new treatments must undergo clinical studies (testing in human volunteers, also called clinical trials). More than 100 clinical studies are now recruiting participants with and without Alzheimer’s disease, related diseases or memory loss to help test these exciting new approaches.
