The Brain Injury Association has debated the 
definition of Brain Injury with the intent of making the distinction between 
Traumatic Brain Injury (TBI)  and Acquired Brain Injury (ABI).  Traumatic Brain 
Injury results from an external physical force such as might occur in a car 
accident, sports event, fall, or anything that involves blunt force to the head. 
Acquired Brain Injury results from an internal event such as a stroke, 
hemorrhage, brain tumor, infection, poisoning, and so forth. An ABI by 
definition encompasses TBIs since both injuries occur after birth.  
I had a hemorrhagic stroke which would be 
defined as an ABI. In my experience, I don't see much difference in terms of 
rehabilitation and recovery regardless of the terminology. Both conditions 
require an enormous amount of hard work, diligence and perseverance. Brain 
injury is brain damage, that is, dead brain tissue, and it is always traumatic. 
Whether acquired, which I believe is a misnomer--it sounds like something sought 
after or pursued, or traumatic, the injury presents enormous obstacles to 
overcome.
