Verbal learning and visuomotor attention in Alzheimer's disease and geriatric depression.
We compared the verbal learning and visuomotor attention of 34 Alzheimer's patients and 18 depressive patients. Verbal learning was assessed using The Hopkins Verbal Learning Test--Revised (HVLT--R); visuomotor attention was assessed using the Trail Making Test (TMT). The Alzheimer's patients had significantly lower scores on immediate and delayed recall of a word list. There was a nonsignificant trend in this group toward a fewer number of true positives and a greater number of false positives. Alzheimer's patients were significantly slower on Trails A, with a nonsignificant trend toward slower performance on Trails B. No difference was observed in accuracy of attentional processing. The results are discussed in terms of other factors, such as stage of cognitive decline, which might have influenced the findings.
