Be mindful of your eyes. They might show early dementia symptoms.
According to a recent scientific discovery from the University of Otago in New Zealand, doctors may eventually be able to identify dementia symptoms in patients by looking into their eyes before memory loss even starts.
Dr. Ashley Barrett-Young, a psychology professor at the University of Otago and the study's principal investigator, stated, "The retina is connected to the brain," according to Money Control.
She added that the retina, the light-sensitive layer at the rear of the eye, is directly connected to the brain as it is a component of the central nervous system. Consequently, alterations in the retina may be a reflection of brain activity, including early indicators of conditions like Alzheimer's.
The eye's blood vessels
She added that small blood vessels in the eye can carry important clues, as they can show early signs of damage that could be linked to dementia.
I also noticed that narrow arteries and wide veins are more common in people with signs of brain aging.
She pointed out that eye examinations would be a tool for early detection of dementia, explaining that cognitive tests often cannot predict the disease but can only indicate it after symptoms appear. Furthermore, brain scans, such as MRIs, are expensive.
On the other hand, retinal examinations are fast, non-invasive, and easy to access.
She emphasized that dilated venules (tiny veins in the eye) appeared in many warning signs, making them a new area to monitor closely.
Don't worry
The study confirmed that there is no cause for panic, as the results do not mean that anyone's next eye exam can predict dementia just yet.

She explained that future brain conditions cannot be predicted through an eye examination. Although the results are promising, further research is needed before they can be used for practical diagnosis.
She also stressed that eye health means more than just good vision, as taking care of your eye health can also be part of how you protect your brain.
