Animal Research Minute – Link Between Brain Injury and PTSD
Could there be a link between traumatic brain injury and post-traumatic stress disorder?
Well, UCLA reports scientists have discovered the first evidence of a causal link between traumatic brain injury, or TBI, and an increased susceptibility to post-traumatic stress disorder. In a new study, scientists trained rats using "fear conditioning" techniques two days after they experienced a brain trauma — ensuring the brain injury and the experience of fear occurred on different days. Rats with the earlier TBI acquired more fear than rats without TBI. This research with rats could help military veterans returning from service overseas.
