Investigating Eye Movement Metrics and Traditional Visuospatial Task Performance in Heterogeneous Alzheimer's Disease

Non-amnestic AD participants showed different relationships between fixation duration and visuospatial function scores for face vs. scene trials, suggesting that more frequent sampling of regions of an affective face may improve visuospatial task performance in non-amnestic AD participants. While preliminary, these findings suggest eye movement metrics may add meaningful information to our interpretation of neuropsychological test performance, and highlight the importance of considering eye movement performance in a clinical context.
