Neurologic tests fall into two groups: tests that examine the structure of the brain and those examining the function of the brain. The first group includes the CT Scan and MRI, the second group includes the EEG, SPECT scan, PET scan, and evoked studies. These tests are commonly used after a traumatic brain injury (TBI), but could also apply for other types of brain disorder as well.
The long-term effects of a brain injury may not be evident for some time. At best, those with a mild brain injury may be able to return to work but will spend the rest of their lives battling a range of Cognitive problems. Others will find themselves dependent on others for the rest of their lives, while the most unfortunate may never emerge from a state of Coma.
