There are four elements needed to diagnose a permanent brain injury.
They are:
- Biomechanical Force Sufficient to Cause Injury to the Brain;
- One of Acute Signs or Symptoms of the ACRM’s definition, of MTBI.:
a) loss of consciousness,
b) change in mental state at around the time of the trauma,
c) amnesia, particularly Post Traumatic Amnesia, or
d) focal neurological deficits. - Neuropsychological Deficits as detailed on a neuropsychological assessment; and
A Person who cognitive function and behavior have changed after the injury
The of diagnosis TBI can be confirmed without a positive imaging study such as a CT or MRI, if these four elements can be proven. The problem is that in the acute stage, the doctors don’t consider the injury serious enough to do a sufficiently detailed inquiry to find and/or document such elements.
