Recovery from traumatic brain injury influenced by one gene

Researchers report that one change in the sequence of the BDNF gene causes some people to be more impaired by traumatic brain injury (TBI) than others with comparable wounds.The study, described in the journal PLOS ONE, measured general intelligence in a group of 156 Vietnam War veterans who suffered penetrating head wounds during the war. All of the study subjects had damage to the prefrontal cortex, a brain region behind the forehead that is important to cognitive tasks such as planning, problem-solving, self-restraint and complex thought. via Health News from Medical News Today Read More Here..
