Learning Issue: Definition: A condition in which there is a traumatically induced alteration in mental status, with or without an associated loss of consciousness. Etiology: Possible mechanisms include compress, which may injure the brain at the point of contact (coup); tensile forces produced in injury at the point opposite the injury (contrecoup) because axons and nerves are stretched; and rotational forces may result in shearing of axons. Risk Factors or Predisposing Factors: Contact sports, and/or risky behavior (eg. Diving into shallow water…); previous concussions. Pathophysiology: The above mechanisms may result in biochemical changes related to perfusion, energy demand, and utilization at the site of the injury. Signs &Symptoms: Headache and dizziness may be present. Vomiting may be present and signify a significant brain injury associated with elevated intracranial pressure.
