Amnesic aphasia has a peculiar position within the aphasic disorders, and it has always been found difficult to bring it into any aphasic scheme. The nearest to it in Head's (1926) classification of symbolic disorder is his nominal aphasia. This, however, is actually a sensory aphasia, in which the difficulty in finding words prevails; it has lost all the characteristics of the classical amnesic speech disorder. Goldstein (1926), on the other hand, while stressing the existence of the amnesic aphasia as a definite and well-circumscribed type of disorder, denies that it has anything to do with a speech defect—an opinion up to then held. According to him, it is fundamentally a defect in the thinking process in which the patients have sunk to a lower and more concrete level of behaviour. They have, according to Goldstein (1926), lost the categorical meaning and use of words; they may be able to name an object in a concrete situation, but are unable to generalize, to use the word in its class meaning. Since then this question has been critically examined by several authors (Hauptmann (1931), Isserlin (1936), von Kuenburg (1930), Lotmar (1933), Scheller (1938)) in the light of Goldstein's conception. In their conclusions, repudiating Goldstein's opinion, they reaffirmed the classical view of a basic speech disorder in the amnesic aphasia.
