Personalized medicine with its promise of developing interventions tailored to an individual's health need and genetically related response to treatment might seem a promising antidote to the documented underutilization of standard depression treatments by African Americans. In addition, understanding depression not merely in biochemical terms but also in genetic terms might seem to counter cultural beliefs and stigma that attach to depression when conceived as a mood or behavioral problem under an individual's control. After all, if there is one thing for which a person is not responsible and cannot be blamed, it is her genes. Nevertheless, for multiple reasons, a personalized medical approach to depression treatment, and its attendant conceptualization of depression and treatment response as genetically influenced, present the risk of exacerbating well-documented disparities in access to, and utilization of, treatment for depression among African-American and Caucasian elderly adults.
