Far from the Groundhog Day spectacle of amyloid-targeting antibodies that do little to nothing for patients in trial after trial, researchers have reported success in reducing the risk of Alzheimer’s disease (AD) in unexpected ways. Researchers at the Cleveland Clinic Foundation have discovered that a Viagra prescription was associated with a roughly 70% reduced risk of being diagnosed with AD. And investigators from the University of Washington reported that in the prospective Adult Changes in Thought study, a long-term study into risk and protective factors for dementia, persons who underwent cataract surgery reduced their risk of AD by 30%, an effect that lasted for 10 years after surgery.
