(Cleveland, OH) -- The effects of even a mild concussion may last much longer than previously thought. A new study finds brain abnormalities months after the symptoms of a concussion fade away.
Dr. Andrew Russman with the Cleveland Clinic says the findings could lengthen recovery time. University of New Mexico researchers compared people who suffered a mild concussion with healthy people of similar age and education. Results show people with concussion reported more problems with memory and thinking skills, dizziness and headaches two weeks later. Brain abnormalities also showed up as many as four months after the concussion. The study is in the journal "Neurology."
Dr. Andrew Russman with the Cleveland Clinic says the study suggests doctors be aware of more possible subtle signs of injury.
