A clinical neuropsychologist is a doctoral level psychologist with specialized training in brain-behavior relationships. A neuropsychologist can provide assessment and interventions to people across the age span. They can aid in the diagnosis of brain disorders, assess cognitive skills, create comprehensive treatment plans, and provide specialized interventions for cognitive rehabilitation. Using standardized assessment measures neuropsychologists compare your performance with others with similar backgrounds as well as compared to your own difficulties in daily life. They provide a report describing your strengths and challenges so that your treatment team can improve your quality of life.
