What're the symptoms of a concussion?
The symptoms of a concussion include severe headache, dizziness, vomiting, increased size of one pupil or sudden weakness in an arm or leg. Concussions result in a temporary malfunction of the brain but no visible physical damage. They may occur after even a minor head injury, depending on how the brain is jarred within the skull. A person who has a concussion may temporarily feel dazed or mildly confused. Consciousness may be lost for a brief time. Memory for events just before or just after the injury may be lost. Most people recover completely within a few hours or days. Occasionally, symptoms of worsening brain function develop hours or sometimes days after the original injury, especially in older people. If these symptoms occur, prompt medical attention is essential. |
