Head injuries refer to any trauma to the scalp, skull, or brain. They can result from various incidents, such as falls, sports accidents, or vehicle collisions. Symptoms may include headaches, confusion, dizziness, or loss of consciousness. It's essential to seek medical attention if a head injury occurs, as some effects may not be immediately apparent. There are two main types of head injuries: closed head injuries, where the skull remains intact, and open head injuries, where the skull is penetrated. Treatment varies based on the severity and type of injury, ranging from rest and observation to surgery in more serious cases.
