A concussion is defined as trauma (e.g. usually but
not always a blow to the head, face or neck) which causes the brain - a
jellylike structure which is normally protected from collisions with
the skull by a tough, fluid-filled membrane - to collide with the
skull. A "concussion" is
derived from the Latin concutere, meaning to shake violently. It is
also often referred to as an MTBI (mild traumatic brain injury). A concussion
typically
results in the rapid onset of symptoms of impaired neurological
function that, in most cases, gradually disappear spontaneously with rest, usually
within a week to 10 days. CT or MRI scans are usually normal.
