The Neuropsychology Casebook was developed to fill the existing gap in the cur­ rent body of literature on clinical neuropsychology. Although texts are available that describe neuropsychological tests and others provide information on syn­ dromes, this volume provides descriptions of neuropsychological test perform­ ance for individuals with various syndromes. It was designed to illustrate the process of clinical interpretation of test findings and report writing for the individual case. Our aims are to provide both the student and practicing profes­ sional with a collection of actual neuropsychological case studies that typify many of the cardinal disorders or syndromes frequently seen by practicing clini­ cal neuropsychologists. We have not provided an exhaustive survey of case studies representing many of the disorders commonly seen in neuropsychology; rather, we have focused on a few select cases that illustrate some of the more common disorders. This book includes detailed case reports complete with referral questions, historical information, relevant neuroradiological findings, actual neuropsycho­ logical test data, and clinical interpretations that take into account all available information on the patient. The cases are discussed in the chapter commentaries with reference to how each compares and contrasts with the prototypic case for that disorder or syndrome. Such case studies help to highlight the various types of behavioral and cognitive sequelae associated with common clinical disorders. The case studies, which are examined through an hypothesis-testing approach, are also aimed at demonstrating how neuropsychological principles and methods are applied.
