Neuropsychological evaluation (NPE) is a testing method through which a neuropsychologist can acquire data about a subject’s cognitive, motor, behavioral, language, and executive functioning. In the hands of a trained neuropsychologist, these data can provide information leading to the diagnosis of a cognitive deficit or to the confirmation of a diagnosis, as well as to the localization of organic abnormalities in the central nervous system (CNS); the data can also guide effective treatment methods for the rehabilitation of impaired patients.
