Most players, coaches and parents are aware of the major signs and symptoms of a concussion (loss of consciousness, vomiting, loss of memory, etc.) but are often unaware of the more subtle signs and symptoms of concussion. Fewer people still are aware that the signs and symptoms of a concussion can take hours or even days to manifest.
Things I have learned about concussions
1. Any violent, jarring motion can result in concussions
Concussions can be caused by more than just direct blows to the head. Anything that causes the brain to be shaken or bounce around in the skull can result in a concussion – think of: whiplash; players colliding together; or, flying through the air while tobogganing and landing with a thud.
