Age-related eye disease linked with cognitive impairment.

Mature adults with low cognitive function test scores may be more likely to have early stages of age-related macular degeneration (AMD). AMD has been thought to share a common pathway with Alzheimer's disease. Both involve similar changes in the brain and eye, and clinical studies suggest that they share similar vascular risk factors. To assess the association of cognitive function and dementia with AMD, Australian researchers screened 2088 people aged from 69 to 97. Participants underwent cognitive testing, retinal photography and an extensive assessment of artery disease. It was found that the one-quarter of people with the lowest scores were twice as likely to have early-stage AMD than individuals with higher scores.
