One Gene Influences Recovery From Traumatic Brain Injury, University of Illinois Study
2/28/2014 7:10:36 AM
Researchers report that one tiny variation in the sequence of a gene may cause 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 injuries 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.
