Mayer and his team matched 50 patients with mild concussions to 50 healthy people of similar age and education levels. They tested all participants in memory and thinking skills, as well as other symptoms such as anxiety and depression.
Kenneth Podell, co director of the Houston Methodist Concussion Center, said the study strengthens the understanding that physical changes within the brain after concussion are separate from mental symptoms. But Podell, who was not involved in the research, added that the study couldn't offer implications for potential long term concussion effects such as depression or dementia.
Special brain scans using technology that is not available in standard brain scans were also given. All tests and scans were repeated two weeks after the concussion, and again four months later.

"Everyone seen at four months should be followed in another four, six or eight months and then re scanned," he said. "One of the Omega Brown Watch biggest problems we Omega Seamaster Deville Gold

Comparing 50 concussion patients with the same number of healthy people, researchers found that the brains of those suffering concussions showed abnormalities four months later. This happened despite the fact that their symptoms had already eased to some degree. National Institutes of Health, is published in the Nov. 20 online edition of the journal Neurology.

"In one or two weeks, most people typically report feeling better," he said. "But when we start talking about it in an analogy of a burn or knee injury, it becomes a little more clear when the doctor says we need to wait a bit longer [to return to prior activities]. It makes sense that the brain would be similar to those tissue types," added Mayer.
The findings, he noted, suggest that the recommendation that athletes suffering concussions should refrain from play for one to two weeks may not be sufficient.

reduced by up to 27 percent four months after injury, brain scans of those with concussions showed abnormalities in the frontal cortex area of both sides of the brain. These abnormalities may have resulted from changes in location of fluid around brain cells or changes in the shape of certain brain cells in response to damage, Mayer explained.
have looking at concussions is we try to predict long term effects from short term findings. This injury is very difficult to commit the type of resources needed to do that kind of very expensive and time consuming study."
Considered a mild traumatic brain injury that occurs from a sudden blow to the head or body, a concussion has symptoms that range from headache and blurry vision to difficulties in sleeping or thinking clearly. Centers for Disease Control and Prevention.
