Cataract surgery could reduce dementia risk
Researchers have found that cataract extraction surgery is associated with a 30% lower risk of dementia onset and a particular decrease in Alzheimer’s disease risk.
In a recent collaborative study, lead by Cecilia Lee (University of Washington, WA, USA), researchers assessed electronic health records from The Adult Changes in Thought (ACT; Kaiser Permanente Washington, WA, USA) study to evaluate how surgical removal of age-related visual impairments affected dementia development. After examining records from more than 3000 over 65’s they found that cataract removal surgery lessened the risk of all-cause dementia by 30%, uncovering new information on how age-related changes in our senses contribute to dementia.
