Excerpt: "Clinical neuropsychology is primarily concerned with how expressions of behavior are affected by brain dysfunction (Lezak, 1995). A neuropsychological assessment consists of a series of systematic clinical diagnostic procedures used to determine the extent of behavioral or cognitive deficits after a person sustains brain injury or damage (see Brain Injuries). It initially involves a clinical interview in which detailed information about the patient's history, premorbid functioning, and factors surrounding the precipitation of the dysfunction or damage are gathered. Often a mental status examination is then performed, in which a brief assessment is made of appearance and behavior, speech and communication processes, thought content, cognitive and memory functions, emotional functioning, insight and judgment, and orientation (Gregory, 1996)."
