Najja Parker, The Atlanta Journal – Constitution – Confusion, sleep loss and mood swings have all been tied to Alzheimer’s disease, but the health of your eyes could also be a predictor.
Alzheimer’s researchers conducted a study to explore eye conditions that may be associated with the brain illness.
They examined 3,877 adults aged 65 and older.
During the five-year trial, about 800 of the subjects were diagnosed with Alzheimer’s.
When researchers took a closer look, they found patients with macular degeneration, diabetic retinopathy, or glaucoma were 40 to 50 percent more likely to develop Alzheimer’s.
“What we found was not subtle,” co-author Paul Crane said. “This study solidifies that there are [many] things we can learn from the brain by looking at the eye.”
While the analysts do not know why there is a relationship between eye illnesses and Alzheimer’s, they wrote, “anything happening in the eye may relate to what’s happening in the brain, an extension of the central nervous system.”
Lead researcher Cecilia Lee added:
“The main message from this study is that ophthalmologists should be more aware of the risks of developing dementia for people with these eye conditions and primary care doctors seeing patients with these eye conditions might be more careful on checking on possible dementia or memory loss.”
