The availability of testing for identified risk genes for Alzheimer disease (AD) in patients with clinically probable AD or their at-risk family members raises important questions for the neurologist. Because the potential benefits and risks of testing vary for each patient, physicians need to evaluate whether it is appropriate on a case-by-case basis. This article outlines the testing decision process and serves as a guide to assist clinicians with associated counseling and result disclosure. Because genetic testing is relatively new and preventive and therapeutic options for AD remain limited, it is important to remain sensitive to and understand the specific challenges associated with obtaining these tests in the routine clinical setting.
