How head trauma affects teens more than adults and how to deal

Keeping kids' heads safe has a lot to do with learning how to manage their injuries. Teens with concussions may take longer to recover than adults, and because their brains are in a rapid, important growth phase, any damage can cause long-term problems.

After a bump, stay calm; sideline your kid, and make sure a medical professional clears them before they return to play, says Dr. Stanley Kutcher, director of the World Health Organization Collaborating Centre in Mental Health at Dalhousie University.
