Am I Eligible?

Answer just a few questions to see if you may be eligible for the AHEAD Study. Take the online survey or if you’d prefer to speak to a representative about your eligibility for the study, please call 1-800-AHEAD-70 (1-800-243-2370).

Participants eligible for the AHEAD Study:
- Are healthy adults ages 55-80
- Have not been diagnosed with Alzheimer’s disease
The AHEAD Study is a four-year clinical trial evaluating a potential treatment to slow the earliest brain changes and help prevent symptoms associated with Alzheimer’s disease. The study requires a number of medical procedures that will be performed at no cost to participants, including:
- Physical examinations
- Memory and thinking tests
- Positron Emission Tomography (PET) scans (pictures of your brain taken by a device similar to an x-ray, after injecting a small dose of a detectable dye in your arm to look for the amyloid plaques and tau tangles associated with Alzheimer’s disease).
- Magnetic Resonance Imaging (MRI) scans (pictures of your brain taken by a device similar to an x-ray to assess changes in your brain structure)
- Blood and urine tests
- Once or twice-a-month intravenous (IV) infusions of an investigational treatment (or placebo) that aims to help remove amyloid plaques from the brain
Are you potentially interested in participating in the AHEAD Study?*
- Yes
- No

Clinical trials carefully assess whether each interested person is eligible to participate. This is done for two main reasons: 1) to protect the health and safety of people who wish to enroll, and 2) to protect the scientific integrity of the study.

Like most clinical trials, the AHEAD Study has specific inclusion criteria - such as being a certain age or having a study partner – and exclusion criteria – such as not having certain medical conditions.

Please answer the 6 questions below to find out if you might be eligible to screen for the AHEAD Study. This should only take a few minutes to complete. At the end, you will be told if you may be eligible and will be given contact information for a research center near you, which you may contact directly, or have your contact information shared with a local research center and have someone there contact you. If you’d prefer to speak to a representative about your eligibility for the study, please call 1-800-AHEAD-70 (1-800-243-2370).
Question 1 of 6*
Are you between the ages of 55 and 80 years old?
- Yes
- No
Question 2 of 6*
The AHEAD Study is a trial for people who have normal thinking and memory function and do not have dementia. Have you been diagnosed with Alzheimer’s disease dementia or another type of dementia, mild cognitive impairment (MCI), or any other cognitive or neurological disorder?
- Yes
- No
Question 3 of 6*
Do you have a pacemaker, defibrillator, or metal implants that would prohibit you from having an MRI? Please note: if the metal object is an artificial knee or hip replacement, please answer “no” as these joint replacements are safe to go into MRI.
- Yes
- No
These next few questions are not required for eligibility for the study – but may help researchers find people who are the best fit for this study.
Question 4 of 6*
Do you have a living or deceased parent or sibling who was diagnosed with Alzheimer's disease or dementia?
- Yes
- No
- Do not know
- Prefer not to answer
Question 5 of 6*
