Cognitive correlates of delusions were examined in 180 probable Alzheimer's disease (AD) patients. Deluded (n = 45) and nondeluded (n = 135) AD patients were equally demented, but deluded patients had relatively preserved attention and worse confrontation naming. In an independent sample of AD patients, the finding of better attention in deluded patients was replicated but the naming difference, although in the expected direction, failed to reach significance. Preserved attention and poor naming may be important for the development of delusions in AD patients.
