MedPage Today (12/6, George) reports, “Cataract surgery was linked to a nearly 30% lower risk of dementia in older adults,” researchers concluded in a 3,038-patient study. The study’s lead author posited, “One possible mechanism by which cataract surgery could decrease the risk of dementia or Alzheimer’s disease is by enabling higher quality sensory input to the retina and therefore improving stimuli to the brain.” The findings were published online in JAMA Internal Medicine. Psychiatric News (12/6) also covers the study.
