Brain injuries are often caused by blunt trauma. Trauma can damage brain tissue, neurons, and nerves. This damage affects your brain’s ability to communicate with the rest of your body. Examples of brain injuries include:
• hematomas
• blood clots
• contusions, or bruising of brain tissue
• cerebral edema, or swelling inside the skull
• concussions
• strokes
Examples of the symptoms of a brain injury include:
• vomiting
• nausea
• speech difficulty
• bleeding from the ear
• numbness
• paralysis
• memory loss
• problems with concentration
Depending on the type of injury you have, treatment may include medication, rehabilitation, or brain surgery.
