Abstract

This study examines the effects of visual perception changes in Alzheimer’s disease (AD) on artistic production and aesthetic experience. Neurodegenerative processes affecting retinal structures and cortical visual systems lead to impairments in fundamental visual functions such as contrast sensitivity, color perception, depth perception, and visuospatial organization. These impairments not only influence daily activities but also transform the ways in which individuals produce art and experience aesthetics. Previous literature reports systematic changes in artworks created by individuals with AD, including loss of perspective, simplification of form, and alterations in color usage. However, artistic creativity does not completely disappear; rather, it undergoes a qualitative transformation in line with cognitive and perceptual reorganization. The relative preservation of the limbic system may enhance emotional intensity and spontaneity in artistic expression. This study provides an interdisciplinary evaluation by integrating perspectives from neuro-ophthalmology, cognitive neuroscience, and aesthetic theory, aiming to explain the relationship between visual perception and artistic expression in Alzheimer’s disease.
