Early detection of Alzheimer's through eye examination!

Researchers at Houston Methodist Hospital in the US have revealed that Alzheimer's disease, which gradually damages human intelligence, can now be detected years in advance through eye examinations. Scientists say that Alzheimer's can be diagnosed at an early stage by detecting changes in the retina of the eye before the disease affects the brain.

According to researcher Stephen Wang, "The eyes are like windows to the brain." Until now, eye examinations have focused only on the central part of the retina, but a recent study has revealed that the first signs of Alzheimer's are in the outer part of the retina. Usually, the disease is detected only after memory loss. The nerves in the brain have already been significantly damaged. This new approach may allow for early treatment.

The main cause of Alzheimer's is the accumulation of 'amyloid protein' in the brain. Scientists have found that a similar protein also accumulates in the retina of the eye. Therefore, changes in the retina reflect the disease in the brain. Experts suggest that regular eye exams in the future may help reduce the risk of Alzheimer's early.
