This book series, in three volumes, draws on the specialized insights and extensive clinical experience of phoniatric experts to offer a basis for the development of concerted European training standards, with the goal of guaranteeing a high quality of phoniatric care for all European patients. Communication disorders in all age groups are covered, and the interdisciplinary character of phoniatrics is mirrored in the inclusion of contributions from a range of other medical and non-medical disciplines. This third volume is devoted to acquired motor speech and language disorders (dysarthria, dyspraxia, and aphasia), swallowing disorders, and phoniatric aspects in treatment of COVID-19 infections. Basic aspects, including etiology and pathogenesis, are fully addressed, and guidance provided on diagnostic methods, differential diagnosis, prevention, treatment/rehabilitation, and prognosis. The reader will benefit from numerous color photos, tables as well as supplementary electronic material, including audio and video examples. This book is intended for residents and practitioners in phoniatrics and also for ENT physicians, medical students, logopedists, and speech and language pathologists and therapists.
