  • the head being struck by an object;
  • the head striking an object;
  • the brain undergoing an acceleration/deceleration movement without direct external trauma to the head;
  • a foreign body penetrating the brain;
  • forces generated from events such as a blast or explosion; and
  • other undefined forces.
