Detection of Visual Memory and Learning Deficits in Alzheimer's Disease Using the Cambridge Neuropsychological Test Automated Battery

Abstract

Alzheimer''s disease (AD) is characterized by marked cognitive and especially mnemonic decline. Microcomputer controlled tests offer a powerful method for assessing these impairments, since precise control over stimulus presentation and responding can be achieved. The recently described CANTAB© (Cambridge Neuropsychological Test Automated Battery) procedure includes a number of visual tasks which can help to pinpoint these deficiencies with accuracy. Using some of the tests available, we describe impairments in nonverbal visual recognition, memory and learning seen in AD.
