What Is the New IDEAS Study?

New IDEAS is a nationwide research study for people who have memory loss. The study is looking at a type of FDA-approved brain imaging called an amyloid PET scan. It is a safe, non-invasive test that takes pictures of your brain.

New IDEAS is trying to find out if your PET scan results help guide your doctor in diagnosing and treating your memory condition. We want to see if this leads to better health for you.

Why Should I Join?

  • Joining New IDEAS is currently the only way Medicare will cover the cost of your amyloid PET scan.

  • Your memory care doctor can use your PET scan results to help diagnose and treat your memory condition.

  • Your participation could lead to better care for you. It could also help your family and many others with memory concerns in the future.

Can I Join?

Your memory care doctor will be able to tell you if you can participate. You may be able to join the New IDEAS Study if you or a loved one:

  • Have noticed some changes in your memory and thinking.
  • Are willing to see a memory care doctor who is part of the study.
  • Have Medicare as your primary insurance.
