Researchers conducted a study they hope provides insight into the frequency and severity of impairment of brain function after a person suffers mild traumatic brain injury (mTBI).
Over a period of three months, the researchers subjected mTBI victims and two control groups to MRI and CT scans and verbal recall tasks that tested and scored metrics related to memory. No improvement in memory was determined by test for mTBI test subjects over the three-month study period.
Researchers determined that the projected recovery of a control group suffering from orthopedic injuries compared favorably to the group suffering from brain injury-an unexpected result. Test subjects with mTBI and who were found to have lesions on their brain performed the recall tasks more poorly than mTBI subjects who did not have lesions.
