Abstract
Examine physician knowledge, preferences, and use of genetic tests for Alzheimer's disease (AD). Survey of 426 community-based physicians treating AD patients. Majority gave inaccurate estimates of AD risk. Medical specialty predicted appropriate use of current tests. Recommending substances to prevent memory loss was related to acceptance of error-free tests. High patient loads and familiarity with genetic tests predicted lower tolerance for test error. Physicians do not endorse indiscriminate genetic susceptibility testing for AD. However, insufficient knowledge of disease risk, etiology, genetic susceptibility, and use of existing tests indicated a need for further physician education in this area.
