With increasing frequency neuropsychologists are being asked to serve as experts in court cases where judgements must be made as to the cause of, and prognosis for brain diseases and injuries. This book describes the application of neuropsychology to legal issues in both the civil and criminal courts. It emphasizes a scientific basis of neuropsychology. All of the contributors are recognized as scientist-clinicians. The chapters cover common forensic issues such as appropriate scientific reasoning, the assessment of malingering, productive attorney-neuropsychologist interactions, and ethics. Also covered are the determination of damages in personal injury litigation, including pediatric brain injury, mild, moderate, and severe traumatic brain injury in adults (with an introduction to life care planning); neurotoxic injury; and forensic assessment of medically unexplained symptoms. Civil competencies in the elderly persons with dementia are addressed a separate chapter, and two chapters deal with the assessment of competency and responsibility in criminal forensic neuropsychology. This volume will be an invaluable resource for neuropsychologists, attorneys, neurologists, clinical psychologists, psychiatrists, and their students and trainees.
