Investigations carried out by New Zealand have found a connection between eye health Dementia. In particular, researchers of a variety of study of the development of tunetin were called blood vessels on the back of the eye MicrovascularThey may show early signs that someone is in danger of making dementia, before the age of 45.
Main co -op, doctor Ashley Barrett-YangIn the Department of Psychology of the University of Otago, these innovations are linked to the previous works of the research team, which, as they recognize the initial symptoms of dementia, “joined the pieces of a puzzle” Reports the university.
The results are premature in the real world, but research continues. “Treatments of Alzheimer and other dementia They are very useful If they start in the early stages of the disease, “says Barrett-Yang.
It is very important to know who will benefit from early treatment, but it is difficult to find the current test methods, It expects it to improve in the future.
Cognitive tests are not enough in the early stages, it is possible A person does not experience any degradation, Other tests such as magnetic resonance and positron emission tomography are expensive and they are not widely available.
“In our study, we analyze the retina, It is directly attached to the brain ”Explains Barrett-Yang. “It is believed that Alzheimer’s pathological processes are reflected in many retina, which is a good goal as a biomarker to identify those who are in danger of developing dementia,” he added.
Posted AlzierrerResearchers used data from the eye studies of the rating In the 45 years of the tunetin study.
Scanners revealed it Harm Narrow (small blood vessels carrying blood from the heart) and Vanulas Wide (the smallest nerves that receive blood from the capillary), and layers of the nerve fibers of the thin retina (which carries visual signals from the retina to the brain) is associated with the high risk of dementia.
“I was surprised that the Venuses were related to many different domains Alzierrer disease; It advises that they may be a particularly effective purpose to assess the risk of dementia, ”Barrett-Yang said.
In spite of the discovery, the scientist says that people should not worry. “This research Is still in the initial stage We cannot predict his future to see an eye study, ”he says.
“Fortunately, we can one day Use AI methods in eye scanners To provide you with an idea of the health of your brain, but we have not yet reached that place, ”the doctor concluded.
