Guidelines for the evaluation of dementia and age-related cognitive decline. American Psychological Association Presidential Task Force

Assessment of cognitive functioning among older adults requires specialized training and refined psychometric tools. Psychologists conducting such assessments must learn current diagnostic nomenclature and criteria, gain specialized competence in the selection and use of psychological tests, and understand both the limitations of these tests and the context in which they may be used and interpreted. Assessment of cognitive issues in dementia and age-related cognitive decline is a core focus of the specialty of clinical neuropsychology. Therefore, these guidelines are not intended to suggest the development of an independent proficiency. Rather, they are intended to state explicitly some appropriate cautions and concerns for all psychologists who wish to assess cognitive abilities among older adults, particularly when distinguishing between normal and pathological processes.
