The theories of what causes mTBI vary, but through research it has been found that there is indeed some consensus as to the origins of mTBI. During the accident that results in the event the brain is thrashed about that skull. The initial site of the impact is known as the “coup,” but what many fail to realize is that this impact is absorbed by the skull, passes through the brain, and then causes the brain to hit against the backside of the skull. This is called the “counter-coupe,” so the brain in fact can receive two injuries from one impact.
