A New Study Shows Brain Health can Depend on Vision

A new study has found that people with untreated visual impairments are significantly more likely to develop dementia.

The research published in the journal JAMA Ophthalmology, examined data from nearly 3,000 individuals and assessed vision using tablet devices with tests for near and distance vision, as well as contrast sensitivity.

The study revealed that even mild vision impairment increased the risk of dementia, and the risk was significantly higher for those with moderate to severe impairment or blindness.

While the study shows a correlation between vision impairment and dementia, it does not establish causation.

It is important to prioritize vision care, including regular check-ups and addressing any identified issues, as the majority of vision impairment and blindness cases are preventable or reversible. Additionally, pairing vision preventive health with rehabilitation services can help individuals maintain independence and cognitive health.
