visual disorders are among the earliest symptoms of Alzheimer's disease. It is, however, still controversial as to whether Alzheimer's disease impairs colour vision. In this study, colour vision of Alzheimer's disease patients was tested using the Ishihara test and the PV-16 choice test. The latter test, primarily designed for children, was chosen in order to avoid problems due to cognitive decline.
