A mild TBI, such as a concussion, may cause a brief loss of consciousness, but it is possible not to lose awareness. Mild TBI symptoms may include fatigue, nausea or vomiting, dizziness, headache, slurred speech and blurred vision.

Another serious TBI is hematoma, or a blood clot that develops when the blood vessels tear. Moderate to severe TBI symptoms may include seizures or convulsions, frequent vomiting, pupil dilation, persistent headaches, balance issues and confusion.
