The relationship between language and another symbolic system, pantomime, was studied in eight mild—moderate Alzheimer patients. The results demonstrated significant correlations and qualitative parallels between pantomime and lexical disturbance in production and recognition. The data are interpreted to support a common symbolic representation shared by words and pantomime which may be independent of limb apraxia and generalized intellectual deficits.
