"This book highlights those rare, difficult to diagnose or controversial cases in contemporary clinical neuropsychology. The evidence base relevant to this type of work is almost by definition insufficient to guide practice, but most clinicians will encounter such cases at some point in their careers. By documenting the experiences and learning of clinicians who have worked with cases that are 'out of the ordinary', the book addresses an important gap in the literature"-- Provided by publisher.
