The prognostic implications of anomia were examined in a group of subjects with mild senile dementia of the Alzheimer type. Anomia was found to correlate with a more rapidly progressive course of illness. A subject''s age did not account for the degree of anomia. Duration of illness was not correlated with the degree of anomia or with severity of dementia. The presence of anomia in a subject with mild senile dementia of the Alzheimer type appears to indicate a more rapidly progressive course.
