Visual impairment associated with a decline in cognitive function
Bottom Line: Worsening vision and declining cognitive function are common conditions among older people. Understanding the association between them could help reduce age-related cognitive changes. A study of more than 2,500 adults aged 65 and older found rate of worsening vision was associated with rate of declining cognitive function. More importantly, vision has a stronger influence on cognition than the reverse. The study finding suggests maintaining good vision through the prevention and treatment of vision disorders in old persons may be a strategy to lessen age-related cognitive changes.
