Elaine Walker is Samuel Candler Dobbs Professor of Psychology and Neuroscience in the Department of Psychology at Emory University. She leads a research laboratory that is funded by the National Institute of Mental Health to study risk factors for major mental illness. Her research is focused on child and adolescent development and the brain changes that are associated with adolescence.
The identification of risk factors for illness is receiving increased attention in all fields of medicine, especially cardiology, oncology, neurology and psychiatry. There are three potential benefits to identifying risk factors. The first is to reduce morbidity by reducing risk exposure. The second is to enhance opportunities for targeting preventive treatment toward those who are most likely to benefit. Finally, the identification of risk factors can shed light on pathological mechanisms.
There are, of course, costs as well as benefits involved in this endeavor. The benefits, in terms of reducing morbidity and mortality, are noncontroversial. The costs, however, can be very controversial and they have generated discussion among ethicists. Foremost among the costs is the potential discomfort and distress that results from the identification of an individual as being at statistical risk for future illness. There are also significant concerns about whether treatment should be initiated prior to the manifestation of symptoms that reach clinical threshold. These concerns are especially salient in the field of psychiatry. In this post, we discuss current efforts to identify risk factors for serious mental illness and the ethical considerations they raise.
