2009-05-12 Eye Disease Linked with Cognitive Impairment



New research suggests older adults with advanced cognitive decline appear more likely to be in the early stages of age-related macular degeneration.

According to the report in the May issue of Archives of Ophthalmology, macular degeneration appears to accompany low scores on tests of cognitive function, including thinking, learning and memory among older adults.

Age-related macular degeneration (AMD) — the leading cause of visual impairment in industrialized nations — has long been thought to share a common pathway with Alzheimer’s disease, according to background information in the article.(Read entire article)

(Reuters Health) - Elderly individuals with cognitive impairment may be more likely than those with intact cognitive function to have early age-related macular degeneration (AMD), according to findings from the Cardiovascular Health Study published in the Archives of Ophthalmology.

"Alzheimer's disease and AMD have long been hypothesized to share a common pathogenesis based on several lines of evidence," Dr. Tien Yin Wong of the University of Melbourne, Australia, and co-authors write. These include similar tissue changes, common circulatory risk factors, and perhaps a shared genetic profile. Clinical and epidemiological studies of this association are lacking, however.
