The ever-increasing number of Alzheimer’s disease among the community has created a chaos in the United States and other countries. Around 5.5 million of American citizens every year are affected by this genetic disorder. It’s been the sixth foremost root of death in America. According to the recent study, researchers found that the symptoms of Alzheimer start emerging through the eyes.
Hence, scanning the retina of our eye can help in early diagnosis of the disease. A joint undertaking of NeuroVision Imaging Center and the Cedars-Sinai enabled scientists to detect signs of Alzheimer disease as early as possible. The disease initially starts humiliating the black portion of the eye and move towards affecting the brain area.
Earlier, scientists noticed generation of a toxic protein called as beta amyloid in the inner portion of the retina by conducting Positron emission tomography (PET) scan test which was quite costlier and troublesome to most of the individuals. Presence of this protein is a clear signal of Alzheimer’s disease.
But this new eye scanning technology is much cheaper and convenient for the entire population who cannot afford PET. The images taken from this technology circuitously reflect the images of an individual’s brain.
According to Dr. Maya Koronyo, an associate professor at Cedars-Sinai, the major advantage of examining the eye scans is its ability to bear multiple scans done after a certain period of time in order to capture the growth of infection.
“We matched the retinal scans of infected people with the controlled group for ensuring that we are on the right track. The technology has served a biomarker to detect the Alzheimer ‘s disease and simultaneously track the improvement of the ailment”, she further added.
Researchers used the approach of the retinal amyloid index (RAI) to calculate the proportion of amyloid deposits in the retina. They found that the fluid quantity increased two times in the patients caught with Alzheimer’s than others who were fit and fine.
