If left untreated, an epidural hematoma is serious and can lead to death. This condition can result from a simple bump on the head or as severe as a head trauma during a car or motorcycle accident. The person may initially appear fine, but symptoms often are present shortly after the head trauma. The symptoms, which may include dizziness, headache, confusion, and lethargy, result from blood pooling between the brain and the skull. The pocket of blood places pressure on the brain. As more blood pools on the brain, symptoms intensify to include seizure and unconsciousness. Seek immediate medical attention after a head injury or the first sign of symptoms. Treatments may range from medication to surgery.
