While past studies have provided compelling evidence that eating a healthy diet, exercising regularly and getting enough sleep are all ways to reduce your risk of cognitive decline, a new study suggests that maintaining healthy vision may slow down cognitive decline in older people. Researchers say that vision fixes, including a new eyeglass prescription or surgery to remove cataracts, can go a long way toward helping seniors stay mentally sharp. In the study, participating adults who had worse vision at the start of the study also had worse scores on a cognitive exam. Why? The researchers say worsening vision can discourage people from brain-stimulating activities like art projects, crosswords and other games, and socializing.
