Document Summary
In order to make diagnostic sense out of the behavioural patterns that emerge in neuropsychological assessment, the practitioner must be knowledgeable about the neuropsychological presentation of many kinds of neurological disorders and their underlying pathology. Defined as an alteration in brain function, or other evidence of brain pathology, caused by an external force. Generally refers to injury involving the brain resulting from some type of impact and/or acceleration/deceleration of the brain. Traumatic brain injury is the most common cause of brain injury. Head injuries resulting from falls are most likely to be incurred by infants and young children. Accident involving moving vehicles account for approximately half of all head injuries in the other age groups. Head injury is still synonymous with tbi, but in some cases it refers to injury of other head structures such as the face or jaw. Primary injury: damage that occurs at time of impact. Secondary injury: physiological processes set in motion by the primary injury.
