How Are Traumatic Brain Injuries Diagnosed?
Diagnosing a traumatic brain injury is a multi-step process. It starts with the patient’s condition at the scene. Looking at factors such as if there was a lack of consciousness, and if so, for how long? Does the person have a memory of the incident, or are they amnesiac? Most importantly, imaging studies. In this age, we have very good imaging techniques to detect even the smallest bleeds in the brain and the smallest evidence of traumatic brain injury, even years after the fact.
Also, the testimony of what we call before and after witnesses. Brain injuries affect people in their day to day function. The best evidence of that is finding the before and after witnesses. The person who knew them before they were injured and after they were injured, about all of the little and big ways that the brain injury has changed that person’s life, as well as the things they are able or not able to do compared to before they had a brain injury.
