Alzheimer’s disease begins in the brain decades before the first symptoms appear. Research suggests that the mind-robbing condition seems to have effects on your retina. According to an expert, keeping your eyes in good health could therefore potentially reduce your risk.
Furthermore, Alzheimer’s disease and dementia, which are both caused by damage to brain cells, both seem to have effects on the retina.
While there’s currently no eye tests that can help diagnose dementia, the research advancements show some potential in this field.
What’s more, the expert said that based on these findings, regular eye tests might be able to reduce the risk of the mind-robbing condition.
Dr Barsam said: “Alzheimer’s doesn’t and can’t cause visual or eye problems, but as there is a high level of visual impairment in people with the disease, research suggests it might represent a risk factor.
“If these vision problems can be treated and corrected, it could go some way towards preventing dementia.
“This means that any intervention that improves a patient’s vision, such as cataract surgery, or even having regular eye examinations might be able to reduce your chances of developing the disease.
“More research is needed in this area, but if the evidence becomes conclusive, it could represent a significant development in understanding the risk factors of Alzheimer’s and how it could be prevented.”
Specsavers recommends having an eye test every two years for most people.

However, if you notice any eye problems, you should see an expert earlier.
Apart from reducing the risk of Alzheimer’s disease, keeping the vision in a good shape could also benefit those who already suffer from the brain condition.
Dr Barsam said: “In addition, patients with dementia often suffer from disorientation so anything which maximises their sensory input accurately, such as having good vision, might be able to reduce some of the associated symptoms.”
While the current research is promising, there isn’t currently enough information to draw a firm link between eye health and dementia.
