It is vital to have the knowledge of the neuroanatomical structures and functional neurological mechanisms, which are disrupted in neurogenic speech/language, disordered persons in order to understand the speech/language deficits themselves. This book provides a comprehensive coverage of the neurological basis of both the clinically recognised forms of aphasia and the various motor speech disorders, in both children and adults. It also covers more recently recognised language disorders, such as Parkinsons and related diseases, right hemisphere damage, closed-head injury, dementia, etc. This is a perfect text for practitioners who need to understand the integration of neuroanatomy and functional neurology with the practice of speech-language pathology.
