Visual impairment associated with a decline in cognitive function

  • A large study indicates that visual impairment can play a role in age-related cognitive decline.

A study involving more than 2,500 older adults (65+) found that the rate of worsening vision was associated with the rate of cognitive decline. 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.
