Brain still injured after concussion symptoms fade

  • 0

New research shows that after a mild concussion, special brain scans show evidence of brain abnormalities four months later, when symptoms have mostly dissipated.

“These results suggest that there are potentially two different modes of recovery for concussion, with the memory, thinking and behavioral symptoms improving more quickly than the physiological injuries in the brain,” study author Andrew R. Mayer, PhD, of the Mind Research Network and University of New Mexico School of Medicine in Albuquerque, was quoted as saying.

Researchers found that two weeks after the injury the people who had concussions had more self-reported problems with memory and thinking skills, physical problems such as dizziness and headaches, and emotional problems like anxiety and depression than people who had not had any concussions. Four months after the injury, the symptoms were reduced significantly by up to 27 percent.
