Terminology:We would like to see consistent definitions as to the nature of the terms Acquired Brain Injury (ABI) and Traumatic Brain Injury (TBI) across the educational, governmental, legal, medical, and larger community. For example, in some medical quarters ABI and TBI are interchangeable terms. In others, ABI is defined as hypoxic or stroke-related, not TBI related. Some authorities add degenerative disorders into the definition of ABI; others specifically exclude such disorders from the definition. The various interpretations of the term acquired brain injury are causing confusion for people with ABI. The Brain Injury Network uses the following definition for ABI: An acquired brain injury (ABI) is an injury to the brain, that has occurred after birth, but is not related to congenital defect or degenerative disease. Causes of ABI include (but are not limited to) hypoxia, illness, infection, stroke, substance abuse, toxic exposure, trauma, and tumor. ABI may cause temporary or permanent impairment in such areas as cognitive, emotional, metabolic, motor, perceptual motor and/or sensory brain function.
