ABSTRACT
In 1894, Alzheimer presented to the annual meeting of the Society of German Psychiatrists in Dresden his observations on twelve cases of arte-riosclerotic atrophy of the brain (reprinted in translation by Forstl and Levy, 1991). The early stages were marked by headache, dizziness, fatigue, and weakness of thinking (Schwache des Gedachnisses). In some cases, the illness began with an apoplectic attack in a person previously in normal mental health. Thereafter, there was increasing weakness of thought and judgment. Definite delusions were usually absent.
