In the foreword to this book, Dr Geschwind mentions that there are over 50,000 patients per year who suffer from a disabling degree of aphasia. Dr Kertesz, in this excellent book on the subject, discusses previous classifications of aphasias, a description of tests used in aphasia, and treatment for and recovery from aphasia. Using numerical taxonomy (the quantitative science of classification and systematics), he has attempted to outline discriminatory characteristics for subsequent identification of aphasic individuals. This has been done most painstakingly with data from the Western Aphasia Battery, in an attempt to provide objectivity and precision for clinical classification, which are much needed for reliable research in aphasia.

There are also excellent chapters on agraphia, alexia,
