In mild concussion, patients may experience headache, dizziness, nausea, blurred vision, tinnitus, balance problems, sleep impairment, difficulty concentrating, or mood changes among other symptoms. In severe traumatic brain injury (TBI), there may be intractable headache, repeated vomiting, papillary changes, altered consciousness, agitation, weakness, numbness, slurred speech, or aphasia. Violence, sports injuries, falls, and car accidents are some of the many causes of TBI.
