A specialized branch of neuropsychology that applies the assessment of the relationship between brain function and behavior in a legal context. It involves examining cognitive, emotional, and behavioral function in individuals involved in civil or criminal cases to determine the presence and severity of traumatic brain injury, neurological disease, or neurodevelopmental disorders. Forensic neuropsychologists use standardized tests, clinical interviews, and additional information to expertly assess issues related to sanity, malingering, disability claims, and the impact of brain damage on behavior. Their work often involves testifying in court.
