American Academy of Neurology: Brain Shows Evidence of Injury Following Concussion after Acute Symptoms have Dissipated
There has been much debate over what happens to the brain following a concussion, much of it recently focused on concussions in sports. One side of the debate maintains that concussions, also referred to as “mild traumatic brain injuries,” involve only a very short term disruption of brain function with no damage to the brain. As discussed in previous posts, this view has been discounted by a growing body of research involving advanced imaging technologies as well as post-mortem pathological studies showing that in a minority of cases concussions can cause lasting damage to the brain as well as persistent symptoms.
On November 20, 2013 the medical journal of the American Academy of Neurology, a professional organization representing 21,000 neurologists and neuroscientists, published findings that after a “mild” concussion, brain scans using diffuse tensor imaging technology, showed grey matter abnormalities on both sides of the frontal cortex.
