LONDON (Reuters) – Experts have developed an eye test that can detect the signs of Alzheimer's disease before the symptoms appear early.
This new technique has shown that retinal vascular networks are scattered among those who suffer from the disease.
This raises the possibility that opticians can check the health of their brains because imaging technology allows doctors to see smaller blood vessels than to display human hair with great accuracy.
Scientists have used test data to compare the retina to Alzheimer's disease patients with those with mild cognitive impairment and other natural spirits.
"The new test measures blood vessels that can not be seen in conventional tests," said Dr. Sharon Fikret, Principal Investigator, Sun Daily.
"Changes in the density of blood vessels in the retina may reflect what is happening in the blood vessels of the brain, and if we could detect these changes in the retina before any change in perception, that would change the situation," he said. -he declares.
"The early diagnosis of Alzheimer's disease is urgently needed, but this can not be achieved with current techniques such as brain screening to identify patients with Alzheimer's disease," he said. he declared.
"The main goal is to use technology to detect Alzheimer's disease before the onset of symptoms and to monitor changes in people participating in trials of new therapies," he said. Dr. Fikret of the Duke University Medical Center in North Carolina.
The new eye test is based on an optical coherence vascular tomography, which allows doctors to quickly examine the blood flow in the small capillaries located at the back of the retina.
