Three Eye Conditions Linked to Higher Alzheimer’s Risk
Three eye diseases have been linked to an increased risk for Alzheimer’s disease (AD), results of a large, longitudinal, population-based study suggest.
Glaucoma, age-related macular degeneration (AMD), and diabetic retinopathy (DR) were associated with a 40% to 50% increased risk for AD.
Participants recently diagnosed with glaucoma had a 46% increased likelihood of developing AD. Similarly, the risk among those recently diagnosed with AMD or diabetic retinopathy had a 50% increased AD risk compared with their counterparts without these conditions.
Although the study evaluated individuals with degenerative eye conditions for subsequent risk for AD or all-cause dementia, there is a potential for the association to be bidirectional. When neurologists evaluate patients for possible dementia, they may also want to ask about eye health, she said.
