Most people equate encephalopathy, post-traumatic sports concussions. The story of the discovery of encephalopathy, post-traumatic sport among american football players and the media storm that followed have been described in the film Concussion. The imagination has done the rest.
But now, a study reveals that trauma moderate-to-repetition may also cause lesions in the brain. Similar to the degenerative diseases Alzheimer’s and Parkinson’s, encephalopathy, post-traumatic sport is characterized by an accumulation of abnormal proteins in the brain.
Neural changes on the duration
“We suspected that the blows that are not responsible for a loss of knowledge – those who do not give of encephalopathy, post-traumatic sports chronic traumatic,” says the lead author of the study Lee Goldstein. “We now have solid scientific evidence to tell “.
The study lasted for seven years. Half of the experiment was to create a head injury in mice close to sports injuries human, and then, in a second time, it was necessary to analyze their behavior and physiology of their brain.
Although the impact level used for each mouse did not cause any loss of consciousness or only a mild reaction during the first and the second reached. But the researchers discovered that tau proteins malformed appeared in the brains of mice 24 hours after the injury. Changes in the ability of neurons to conduct nerve impulses began shortly after, and then persisted in the long term.
