Research shows an association between cognitive decline and vision impairment among older Americans.
Analysis found that among adults aged 45 years and older, subjective cognitive decline (SCD)-related functional limitations were three and a half times higher among adults with vision impairment than those without. The findings were published in the Morbidity and Mortality Weekly Report, produced by the Centers for Disease Control and Prevention in the US this May.
The number of Americans with vision impairment is expected to double over the next three decades. Alongside similarly alarming increases in dementia, researchers increasingly look to the eyes for early detection of cognitive decline.
