Clinical neuropsychology is a sub-specialty of clinical psychology that specializes in the assessment and treatment of patients with brain injury or disease. A clinical neuropsychologist usually holds an advanced degree in clinical psychology and has completed a clinical internship and specialized post-doctoral training in clinical neuropsychology. What distinguishes a clinical neuropsychologist from other clinical psychologists is knowledge of the brain, including an understanding of areas such as neuroanatomy and neurological disease.
The discipline involves the application of standardized measures in the study of brain behaviour relationships. They use neuropsychological tests to assess cognitive deficits, and they are involved in the management, treatment and rehabilitation of cognitively impaired patients. Neuropsychology also entails the development of models and methods for understanding normal and abnormal brain function.
