No positive association was found between age-related macular degeneration and Alzheimer’s disease or dementia, according to a study.

Researchers examined English National Health Service hospital episode statistics from Jan. 1, 1999, to Feb. 28, 2011, which comprised 65,894 patients with AMD and 168,092 patients with dementia; more than 7.7 million people were in a reference cohort.

Subjects were analyzed for risk of Alzheimer’s disease or dementia after diagnosis of AMD and risk of AMD after diagnosis of Alzheimer’s disease or dementia.

No elevated risk of Alzheimer’s disease or dementia after AMD was reported, and there was a low likelihood of being of being admitted to the hospital with AMD after Alzheimer’s disease or dementia.

The study authors also found that subjects with dementia in England were less likely to receive treatment for AMD.

“Further research across a variety of countries is required to determine whether people with dementia are receiving appropriate investigation and treatment for AMD, as well as identify and address any potential barriers,” they said.
