Small Scan Study: Even Mild TBIs May Affect Brain Matter, Cognition.

Scientific American (7/17, Yuhas) reports that a study published online July 16 in the journal Neurology reveals that even a mild traumatic brain injury (TBI) may affect brain matter and cognition. The study’s findings “hint that the contusions leave a lasting trace in the brain.”
The Fox News (7/17, Kwan) website reports that researchers arrived at that conclusion after “working with a group of 44 people with mild TBI, nine people with moderate TBI and a control group of 33 healthy” matched individuals to whom they “administered DTI scans within one week of injury,” along with “the Glasgow Coma Scale (GSC) test to measure cognition.”
