Better life for caregivers Improved quality of life was also reported by caregivers of the patients who had cataract surgery, according to the study. The report was scheduled for presentation at the Alzheimer's Association's annual meeting in Copenhagen, Denmark. "Our findings need to be verified in a larger study, but they suggest the need to aggressively address dementia co-morbidities such as vision-impairing cataracts, while balancing safety and medical risks," Lerner added in an association news release.

Other interventions to offset sensory loss – including vision and hearing – may help improve quality of life for people with dementia and their caregivers," Lerner said.

"Appropriate thoughtfulness and restraint are necessary when considering surgery or other procedures for people with Alzheimer's or another dementia," Carrillo said. "However, we should not assume that medical procedures cannot be pursued or are too risky."
