Vision Decline Predicts Cognitive Decline, NeuRA Study Reveals
A 12-year study by Neuroscience Research Australia (NeuRA) has uncovered a significant link between declining vision and cognitive deterioration, including dementia. Led by Dr. Nikki-Anne Wilson, the research emphasizes that even treatable vision impairments may accelerate cognitive deterioration by reducing mental stimulation and social engagement, both vital for maintaining brain health.
The findings underscore the need for regular vision screening, particularly among older adults, to identify and address vision issues early. Poor vision can lead to social isolation, diminishing cognitive function, and increased dementia risk. By promoting timely interventions, NeuRA advocates for equitable access to eye care services, suggesting that improved vision health could help mitigate the global burden of dementia.
“While people are encouraged to get regular eye tests, this research highlights that vision checks are important from a cognitive perspective as well,” Dr Wilson said. “It is normal for some loss of visual acuity to occur with age, which refers to how clearly objects can be seen from a distance. However, just as we are advised to get our blood pressure checked, we should also get our eyes checked.”
“A decline in vision can be caused by a range of factors, some of which are treatable. For example, cataracts, or vision decline that can be supported with the correct glasses,” Dr Wilson said. “The research is now showing that identifying these changes early and addressing them may help reduce the risk of developing dementia.”
This research further strengthens the argument for integrating eye health into broader strategies for cognitive preservation, especially as the population ages.
