I'm Dr. David Vastola and Patrick and I love coming out here to watch the kids play soccer and football but there are some inherent hazards. Number one is hike! The reason I'm talking about is concussion. About 1.2 million of our kids play sports every year and out of that 65,000 experience concussions - that's where there's a brain bruise because of the trauma to the head. Now up until now, we felt that as long as the concussion doesn't last more than 15 minutes our children can go back in the game. Disorientation, confusion, double vision are some of the symptoms - but if it went away in 15 minutes, you can resume play.
