The Investigating Training Associated Blast Pathology study funded by the Defense Health Agency is taking five years to study the effects of repetitive blasts on Navy SEALS. Training and missions carried out by these elite teams often involve the use of heavy weapons. Dr. Michael J. Roy, MD, MPH, is a Professor of Medicine at the Uniformed Services University and the Director of Operational Research for USU’s Center for Neuroscience and Regenerative Medicine. Roy is examining possible sub-concussive brain injuries due to repetitive blasts over time from weapons such as the Carl Gustav recoilless rifle. The study will use blast gauge sensors and other techniques to monitor the participants to determine both immediate and long-term effects on the brain.
