Watch Out for Mild Head Trauma

Monday, 03 November 2008 15:24
Mild head traumas, like those suffered in motor vehicle collisions and sports injuries, are often more serious than many doctors realize, say researchers.

Investigators examined positron emission tomography (PET) scans of 42 subjects who had withstood mild head trauma during the past month. In total, 84% of participants showed reduced brain glucose uptake, an indicator of brain damage. In addition, 61% of patients had Glasgow Coma Scale (GCS) scores in the comatose range.
