Detect Alzheimer’s Through Your Eyes

· December 18, 2014

Recent studies conducted in the United States and China have shown that it is possible to detect Alzheimer’s through your eyes. This is because your eyes are related to your brain and some of its most important activities. In the following article, we will give you a little more information on this topic that will surely surprise you.

What Is Alzheimer’s?

Alzheimer’s disease affects your brain and some of its functions, mainly the cognitive and behavioral functions. That is why it is considered a neurodegenerative disease, suffered mostly by people over the age of 65.

One of the most common symptoms of Alzheimer’s is the inability to acquire new knowledge and use memory. Therefore, Alzheimer’s causes the gradual loss of immediate memory and other mental abilities. Currently, this disease is the most common form of dementia, and is incurable and terminal. From its diagnosis, the disease tends to last ten years.

Eyes and Their Relationship to the Detection of Alzheimer’s


Researchers from the Medical Center of Georgetown University in the United States and at the University of Hong Kong in China discovered that there is a relationship between the loss of a layer in the eye‘s retina and the onset of Alzheimer’s through an experience done on rats in a laboratory.

In general, this investigation consists of analyzing the retina of said animals, which had been genetically manipulated to develop the disease. In contrast to other studies that had been done in the past, in this case the scientists measured the thickness of the retina, including its part of the interior layer and that of the ganglion cells.

In this way, they discovered that the rats that had Alzheimer’s disease experienced a sizeable reduction in the thickness of the analyzed layers. On the other hand, the healthy rats did not show substantial changes in their retinas.

This investigation is of course not definitive because of how much there is left to research. Nonetheless, it opens the possibility of being able to detect this serious disease through your eyes.

In any case, it’s best to follow some simple recommendations that will probably avoid or delay the onset of Alzheimer’s. For example, you should have a healthy lifestyle, exercise, and keep your brain active. It has been proven that exercising your brain helps against cognitive diseases.


In this way, it’s best to reas, learn new things like languages or a hobby, constantly analyze things that interest you, do something artistic or sporty, or write. By doing these simple and everyday activities, you will have less possibilities of having problems in the future.

If you are of age, it is very important to do studies that diagnose if you have the disease. If so, there are some options that, although do not cure the disease, enable you to have the best life as possible. In fact, there are public programs that inform the patients as well as the family members.
