Cataract surgery may lower dementia risk

  • An observational study of more than 3,000 adults aged 65 years or older has uncovered a link between cataract surgery and a reduced risk of developing dementia, including Alzheimer’s disease.
  • The researchers say the results support the connection between sensory impairments, such as vision loss, and a higher risk for dementia.
  • The scientists also believe there is a link between blue light and the development of dementia.

More than 55 million peopleTrusted Source worldwide live with dementia — a syndrome that causes a decline in cognitive functions such as memory, language, and comprehension.

Alzheimer’s disease is the most common form of dementia, accounting for 60–80% of all people who have dementia. Scientists have carried out much research over the years examining the causes of Alzheimer’s; however, they remain unclear.

Researchers from the University of Washington School of Medicine in Seattle now say they have uncovered a link between cataract surgery and a lowered risk for developing dementia in older adults, including Alzheimer’s disease.

Can Wine Ward Off Cataracts?

Cataracts are a threat to the vision of millions, but new study suggests a welcome aid to prevention: wine.

A few glasses of alcohol — especially red wine — a week may help reduce your risk of cataract surgery, new British research suggests.

“The fact that our findings were particularly evident in wine drinkers may suggest a protective role of polyphenol antioxidants, which are especially abundant in red wine,” said study lead author Sharon Chua, a researcher from University College London Institute of Ophthalmology. Her team noted that grape skin is abundant in with healthy antioxidants, an antioxidant-like compound known as resveratrol, and other heathy chemicals called flavonoids.

Too much alcohol — a drink a day or more — wasn’t great for eye health, however. In heavier drinkers, the odds for cataracts actually began to rise, according to the study.

Cataracts often develop with age and occur when the normally clear lens of the eye becomes clouded.

Cataracts are one of the leading causes of reversible vision loss and blurry vision in the world,” said Dr. Matthew Gorski, an ophthalmologist at Northwell Health in Great Neck, N.Y., who wasn’t involved in the new study.

* Don’t smoke. Smoking triples the risk for cataracts and is also a risk factor for macular degeneration and its response to treatment.

*Wear sun glasses that are UV protective.

* Wear safety glasses for high risk activities.

* Pay attention to nutrition. You need fruits and leafy vegetables, Omega 3 fatty acids and vitamins A, C and E. In a study about folks who ate leafy green vegetables, there was a five fold increase in cataract prevention over those who ignored leafy green vegetables in their diet.

* Don’t ignore symptoms. Many afflictions of the eye like glaucoma are irreversible, however, they can be handled when caught early.

* Get regular eye examinations.
