Frequently Asked Questions

22. What is clinical research and why is it an important part of Alzheimer's disease research?

Clinical research is medical research involving people. It includes clinical studies, which observe and gather information about large groups of people. It also includes clinical trials, which test a medicine, therapy, medical device, or intervention in people to see if it is safe and effective.

Clinical trials are the best way to find out whether a particular intervention actually slows, delays, or prevents Alzheimer’s disease. Trials may compare a potential new treatment with a standard treatment or placebo (mock treatment). Or, they may study whether a certain behavior or condition affects the progress of Alzheimer’s or the chances of developing it.
