Should Soldiers Take a Genetic Test for Vulnerability to PTSD?
Based on evidence that vulnerability to post traumatic stress disorder is partly genetic, some researchers say that soldiers should be offered a genetic test before they deploy in order to help guide PTSD management. The test identifies genetic determinants of low levels of dopamine, a brain chemical. But others raise scientific and ethical concerns. For one thing, the connection between low dopamine and PTSD has not been established. In addition, a critical financial conflict of interest with the primary researcher who recommends this genetic testing was not disclosed. This debate is one of many developments at the intersection of genetics and the brain covered in the current issue of Braingenethics, a newsletter produced by a collaborative project of The Hastings Center and Columbia University Medical Center.
