Concussion, also known as mild traumatic brain injury, is an acute urgent public health issue that has the potential for serious long-term consequences if not recognized immediately. It is a complex injury affecting the brain both structurally and functionally as a result of neurological deficits that occur when the brain is jostled inside the skull. This particular injury is unique in that no two concussions are alike, as each patient responds differently. One may take a significant hit and recover uneventfully in days, while another may take a seemingly minor hit and yet still be recovering months later. There are no diagnostic tools currently available to assess a concussion and, as a result, diagnosis is not an exact science. Every concussion needs to be treated on a case-by-case basis, usually taking into consideration previous history, circumstance of injury and presenting signs and symptoms.
