| Opplysninger | Thirty-one patients with mild-to-moderate Alzheimer's disease (AD)underwent a test battery of complex visual tasks. We assessed thescores using a principal-factor analysis to elucidate the underlyingdeficits. There were three independent factors: The first factorincluded the tasks of identifying and comparing forms of visualstimuli. The second factor consisted of digit span and digit symboltasks, and the third factor consisted of a specified visual countingtask. We considered these three factors as representing thedysfunctions of object recognition, general attention and spatialrecognition, respectively. These results underline the disturbancesof the two visual systems, object vision and spatial vision, in early-AD patients.
