“Few studies have looked at whether traumatic brain injuries cause impulse control problems,” said the study’s lead author, Cole Vonder Haar, a former postdoctoral research fellow in the UBC department of psychology who is now an assistant professor at West Virginia University. “This is partly because people who experience a brain injury are sometimes risk-takers, making it difficult to know if impulsivity preceded the brain injury or was caused by it. But our study confirms for the first time that even a mild brain injury can cause impulse control problems.”
