• Two psychometric tests designed to evaluate "verbal fluency" and "naming" as a measure of semantic memory were presented to 18 patients with Alzheimer's-type dementia, 16 other patients with multi-infarct dementia, and 14 age- matched control subjects. The diagnosis of multi-infarct dementia and Alzheimer's-type dementia was based on the commonly accepted criteria of the Diagnostic and Statistical Manual of Mental Disorders, ed 3. Although the patients with Alzheimer and multi-infarct dementias, respectively, suffered from a comparable degree of dementia (as determined by the Mini-Mental State examination), semantic memory was not specifically impaired in Alzheimer's-type dementia as opposed to multi-infarct dementia. In contrast semantic memory was correlated with the degree of dementia in both disease entities.
