Concussion damage lasts for months
Research published in the journal Neurology suggests athletes may be returning to their sports too quickly after suffering a concussion.
The study, conducted by scientists from the University of New Mexico, compared the brains of 50 people who had mild concussions to 50 healthy people. Those who suffered a concussion initially had problems with memory, headaches and dizziness, but those symptoms cleared up after a few weeks. However, four months later, doctors were still able to see differences in the way fluid moved through the brain, suggesting that it still had not healed.
Unfortunately, in the US, athletes often return to their respective sports a week or 10 days after suffering a concussion because the physical symptoms of the injury start to diminish. But the research shows the brain tissue has not actually healed.
