Head Trauma Symptoms
What Are the Symptoms of Head Trauma?
Head injuries can cause a wide variety of symptoms, depending on the type, severity, and location of the injury. Sometimes, the signs and symptoms may not show up right away. According to the NINDS, head injuries fall into three categories:
- Mild head injury. The person sustains some injury to the outside of the head, but he or she may not lose consciousness or may lose consciousness for a few seconds or minutes. The injured person may feel dazed and complain of a headache.
- Moderate head injury. The person is injured on the outside of the head and may lose consciousness for a longer period of time. Other symptoms can include memory loss, headache, dizziness, drowsiness, nausea and vomiting, and confusion. The area around the eyes may be a different color. A clear fluid may ooze from the nose.
- Severe head injury. There may be serious damage to the outside of the head but external signs of trauma are not always visible. This person may have similar symptoms as those above only more severe. In most cases, the person is either unconscious or barely responsive.
