“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,” said study author Andrew R. Mayer, PhD, of the Mind Research Network and University of New Mexico School of Medicine in Albuquerque.
