Does brain injury run in the family?

It’s a question we’ll likely hear more often after scientists link genes and a susceptibility to brain injury.

“Until now, all the attention has been paid to how hard and how often you get hit,” said Thomas McAllister, a professor of clinical psychiatry at the Indiana University School of Medicine. “No doubt that’s important. But it’s also becoming clear that it’s probably an interaction between the injury and the genetics of the person being injured.”

The findings are timely as another new study has found that concussion diagnosis doubled in young athletes from 2005 to 2012. It’s a reality causing parents to carefully consider whether to permit their kids to play contact sports.
