• In a previous investigation by Storandt and coworkers, a brief battery of four neuropsychological tests was found to accurately distinguish a sample of patients with senile dementia of the Alzheimer type (SDAT) from normal elderly persons. The present study examined the value of these tests in the distinction between SDAT and dementias of other etiologies. Our results replicated those of Storandt and coworkers in that these tests did distinguish normal persons from patients with both SDAT and other dementias. These tests, however, did not accurately differentiate among the dementias. These results indicate that assessment batteries utilizing additional procedures to supplement cognitive testing are indicated to more accurately discriminate among the dementias.
