Comparison of the Cerad and CVLT List-Learning Tasks in Alzheimer’s Disease

Abstract

This investigation examined the relationship of the word list from the CERAD neuropsychological battery to the California Verbal Learning Test (CVLT) in a sample of 138 subjects with Probable Alzheimer’s disease (AD). Results revealed modest but statistically significant associations between the two measures on many key variables. Total words learned showed the strongest association, with lower correlations for delayed recall, intrusion errors, and recognition variables. As expected, the CERAD and CVLT assess similar aspects of verbal learning in patients with AD. However, the modest level of many of the correlations suggests that caution should be exercised in applying the same interpretive strategies derived on more comprehensive measures to shorter ones.
