This 2001 definition expands upon and modifies the 1989 definition by Division 40 of the American Psychological Association, which was used as the foundation for this updated document.
A clinical neuropsychologist is a professional within the field of psychology with special expertise in the applied science of brain-behavior relationships. Clinical neuropsychologists use this knowledge in the assessment, diagnosis, treatment, and/or rehabilitation of patients across the lifespan with neurological, medical, neurodevelopmental and psychiatric conditions, as well as other cognitive and learning disorders. The clinical neuropsychologist uses psychological, neurological, cognitive, behavioral, and physiological principles, techniques and tests to evaluate patients’ neurocognitive, behavioral, and emotional strengths and weaknesses and their relationship to normal and abnormal central nervous system functioning. The clinical neuropsychologist uses this information and information provided by other medical/healthcare providers to identify and diagnose neurobehavioral disorders, and plan and implement intervention strategies. The specialty of clinical neuropsychology is recognized by the American Psychological Association and the Canadian Psychological Association. Clinical neuropsychologists are independent practitioners (healthcare providers) of clinical neuropsychology and psychology.
At present, board certification is not required for practice in clinical neuropsychology. Board certification (through formal credential verification, written and oral examination, and peer review) in the specialty of clinical neuropsychology is further evidence of the above advanced training, supervision, and applied fund of knowledge in clinical neuropsychology.
1Individuals receiving training in clinical neuropsychology prior to this 2001 definition should be subject to the educational and experiential guidelines published by Division 40 of the American Psychological Association (APA, 1984; 1989). The 2001 definition should not be interpreted as negating the credentials of individuals whose education and experience predates the Division 40-APA definitions. Individuals meeting these prior criteria are and continue to be clinical neuropsychologists under this 2001 definition.
