QUESTIONS & ANSWERS:
QUESTION: On the pre-injury questionnaire, the question refers only to "brain injury," not specifically traumatic. Is this a problem? 
ANSWER: This difference is not important. The term "brain injury" is popularly used to refer to what the medical world refers to as "traumatic brain injury". For example, newspaper descriptions of auto accidents refer to "brain injury" rather than "traumatic brain inury". Also, as commonly used, the term "brain injury" does not include damage due to non-traumatic causes. Newspaper descriptions of persons who have suffered brain damage due to inhaling fumes or being without oxygen refer to "brain damage" rather than "brain injury".   (09-08-2005)
