Much of the public is aware that head injuries are a major problem for many athletes. USC neurosurgeon Gabriel Zada, MD, assistant professor of clinical neurological surgery, Keck School of Medicine of USC, is conducting studies about the effect of concussions on the brain. Zada points to new evidence showing the significance of a single hit to the brain. His work is contributing to the development of new guidelines designed to protect young athletes following head injury. Zada’s research career development was supported by SC CTSI’s KL2 program.
