Traumatic brain injury
In concussion, patients may experience headache, dizziness, nausea, blurred vision, tinnitus, balance problems, sleep impairment, difficulty concentrating, or mood changes, among other symptoms. In severe TBI, there may be intractable headache, repeated vomiting, pupillary 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. Survivors may have significant and permanent disability. The mechanism and location of the injury affect the pathology of the injury and prognosis for recovery.
