Summary

Although there are a number of well-known reference texts on language disturbances after acquired brain damage which uncover the classical syndromes of aphasia (e.g., conduction aphasia) in a comprehensive fashion, there has, until now, been no monograph on the different clinical, linguistic, and neuroanatomical aspects of transcortical aphasias. This book offers a comprehensive, contemporary, and scholarly account of transcortical aphasias by combining valuable information on cognitive neuropsychology, neuroimaging and functional localization of residual repetition and other language functions among patients with transcortical aphasias. The book covers: historical aspects; assessment of language deficits from a clinical and psycholinguistic perspective; clinical phenomenology, aetiology, neural substrates, and linguistic mechanisms underlying each of the three clinically established variants of transcortical aphasias (motor, sensory, and mixed); associated phenomena such as echolalia, completionphenomenon, automatic speech, and prosody; and neuroanatomical correlates including structural and functional neuroimaging. Each chapter presents the description of original and published cases which illustrate the various clinical patterns of transcortical aphasias. Transcortical Aphasias should be of value to advanced undergraduates, speech pathologists, linguists, neuropsychologists, cognitive neuropsychologists, and behavioral neurologists.
