This section describes the signs and symptoms of language disorders that are encountered most frequently in the clinical setting. In general, it follows the outline of dysphasia syndromes offered years ago by Wernicke (1874, 1885–1886) and Lichtheim (1885), and recently reformulated by Geschwind, Goodglass, Benson, and their associates (Geschwind, 1965; Goodglass and Kaplan, 1972; Benson and Geschwind, 1976; Benson, 1979). This System of Classification has been chosen largely because it is by far the most commonly used method of grouping dysphasic patients to be found in the recent literature. There have been other published and widely used classifications of dysphasia, notably those of Head (1928), Weisenburg and McBride (1935), and Luria (1970), and where they correspond to the syndromes described in this chapter, the similarities will be pointed out.
