A longitudinal study of 2520 older US adults has found an association between worsening vision and declining cognitive function.
In the JAMA Ophthalmology study, the authors highlighted that visual acuity rather than cognitive impairment is likely to be the “driving force” in this association.
The connection between visual loss and cognitive decline was stronger than the reverse trend (where reduced cognitive performance is linked to poorer vision).
They found that worsening vision in older adults may be negatively associated with future cognitive performance.
“Maintaining good vision may be an important interventional strategy for mitigating age-related cognitive declines,” the authors concluded.
