psyc 185 exam 4: Brain Injury

what is BIAA?

"An acquired brain injury (ABI) is an injury to the brain that has occurred after birth and is not hereditary, congenital, degenerative. The injury commonly results in a change in neuronal activity which affects the physical integrity, the metabolic activity, or the functional ability of the cell. The term does not refer to brain injuries induced by birth trauma."

Traumatic brain injury (TBI) is an insult to the brain, not of a degenerative or congenital nature but caused by an external physical force, that may produce a diminished or altered state of consciousness,which results in an impairment of cognitive abilities and/or physical functioning. It can also result in the disturbance of behavioral or emotional functioning. These impairments may be either temporary or permanent and cause partial or total functional disability or psychosocial maladjustment."
