I was referred to the state TBI agency for some assistance.

Unfortunately the nice local agency that referred me to the state agency defines TBI differently from the state agency. My TBI was from brain surgery that went wrong. For the state people, that doesn't qualify as a traumatic brain injury, so I don't qualify for help.

They only accept people with sports injuries - not anyone with traffic accidents, or anyone with congenital brain injuries.

I've been in therapy with folks with all sorts of brain injuries.

So I'm curious - is there an official definition of TBI? I'd love to have some assistance, but mainly, I'm confused, and I want to clear up the confusion?
