You can get a concussion without damaging your helmet.
I got a concussion in a car accident when some kids hit me: I was scratched up and bruised, but no injuries to my head - still had a concussion though.
Concussions come from your brain hitting the inside of the skull: Any change in movement of sufficient force might cause one.
