Head trauma refers to any injury that occurs to the head or brain as a result of an external force. This can include injuries caused by accidents, falls, sports-related incidents, violence, or other types of impacts. The severity of head trauma can vary greatly, from mild (such as a concussion) to severe (such as a skull fracture or brain hemorrhage). Head trauma can have various symptoms depending on the location and extent of the injury, but may include confusion, dizziness, memory problems, headaches, nausea, vomiting, vision changes, and loss of consciousness. Treatment for head trauma typically involves rest, medication to manage pain or other symptoms, and in some cases, surgery.
