Doctors may be able to predict your risk of developing dementia by looking into your eyes.
Blood Vessels in the Eyes and Brain
In February 2018, a study published in the journal Neurology revealed that people whose eyes show changes in blood vessels at age 60 are at risk of developing cognitive problems when they reach 80 years old. Researcher Jennifer Deal and her team from John Hopkins University said that problems in the brain’s blood vessels are as crucial as problems with larger arteries when it comes to influencing cognitive decline. The researchers noted that looking at the eye’s blood vessels might help doctors understand what is happening in a person’s brain because of the anatomical similarities of the blood vessels in the eyes and the brain.
Vision Loss and Decline in Cognitive Function
In June 2018, a study published in the journal JAMA Ophthalmology arrived at a similar conclusion. In a study involving more than 2,500 Americans, Dr Diane Zheng from the University of Miami found a link between vision loss and declining cognitive function.
Taking Care of the Eyes
A healthy lifestyle can help ward off vision problems. A diet rich in zinc, lutein, omega-3 fatty acids and the vitamins C and E may help protect the eyes from age-related eye conditions such as cataract and macular degeneration. People who do not smoke and engage in physical exercise also have a lower risk of developing serious eye problems. Make it a habit to wear sunglasses as these can protect your eyes from the harmful UV rays of the sun. Luxury brands such as International Eyewear have glasses that can block UVA and UVB rays. Polarized lenses can also help reduce glare when you drive.
Studies have shown a link between eye and mental health. Protecting your eyes can help reduce your risk of memory loss and mental decline.
