It is now widely expected that scientific evidence and theory should be used to describe aphasia and aphasia therapy. This book provides review chapters on controversial research and clinical issues in aphasia and aphasia therapy. Contributions from distinguished scholars from all over the world (Europe, America, Australia) cover the range of disciplines involved in aphasia, including neurology of aphasia, cognitive and linguistic approaches to aphasic therapy, psychosocial approaches, aphasia research methodology, and efficacy of aphasia therapy. This book brings together contributions of all these disciplines and makes a link between theory and therapy from a scientific perspective. Each chapter offers a current review with extensive references, thus providing a useful resource for clinicians, students and researchers involved in aphasia and aphasic therapy including doctors, psychologists,linguists and speech and language therapists. The papers in this book were presented at the first European Research Conference on Aphasia.
