Retina geography not associated with cognitive decline
Retinal vascular changes do not show non-pathological age-related cognitive decline, researchers say. The study, however, does not rule out the use of retinal information in diseases such as Alzheimer’s.

Sarah McGrory and colleagues at the University of Edinburgh in Edinburgh, United Kingdom, published the finding in the British Journal of Ophthalmology.

The retina offers a potential non-invasive window into changes in the brain. Previous research has shown associations between retinopathy and retinal branching parameters, poorer verbal memory, information processing speed, and executive function. However, these associations appear stronger in younger people than in older ones...
