Picture emerges of how kids get head injuries

A study of over 43,000 children with head trauma found that falls were the most common cause of head injuries in children under 12, while assaults, sports, and car crashes were more prevalent in teenagers. The findings suggest that CT scans may be overused during diagnosis, and could help policy makers develop injury-prevention measures.
