Ideomotor apraxia and ideational apraxia
—their problems and differential diagnosis—

Abstract

    The definition, the classification and the examination of ideomotor apraxia and ideational apraxia was reviewed. The definition and the classification was followed by Yamadori (1984) in this article. According to his definition and classification, both the transitive movement and the intransitive movement contain in ideomotor apraxia test and the subclass of ideomotor apraxia might be indicated. In terms of ideational apraxia, the differential diagnosis among semantic memory disturbances and multimodal agnosia must be needed and the precise clinical observation can differentiate these three categories.
