Alabama residents who have sustained head trauma or who work in risky professions may be interested in a new study from New York University's Langone School of Medicine, which has found that even mild traumatic brain injuries, such as those suffered in a concussion, can result in long-term structural damage to the brain. Approximately 1.7 million people each year suffer a traumatic brain injuries, about 75 percent of which are classified as mild. These injuries can occur due to a blow to the head or during an accident in which the victim experiences whiplash. The study examined 28 patients with mild traumatic brain injury along with a control group of 22 people. Some of the participants were subjected to an MRI one or two months after injury and then again one year later. Even after a year, researchers found measurable differences in brain volume and damage to certain regions in the brain when victims of brain injury were compared to the control group.
