The purpose of neuropsychological assessment is to explore and understand an individual’s intellectual, emotional and perceptual abilities in relation to day-to-day problems experienced and to provide a diagnostic formulation that includes comment on health of brain function as well as to offering therapeutic recommendations. Assessment of this type is a well-established branch of clinical psychology. Typically, a profile of the individual’s psychological condition and a diagnostic formulation is provided in this type of assessment. Clients who have been injured in accidents are often referred for neuropsychological assessment by personal injury lawyers. In this case, the assessment can be helpful for settling insurance claims. Detailed interview and use of published, standardized psychological tests and questionnaires are the major means by which this type of assessment takes place. Major areas of exploration are memory, concentration, executive function (ability to plan, initiate, pursue and complete everyday goals), and emotional dynamics.
