New technology can detect early warning signs of Alzheimer's disease

U.SDuke researchers developed a new imaging technique that can detect the thickness and texture of each layer of the retinaThey recently issued a research report, retina textures can provide early biomarkers of Alzheimer's disease, and its development of imaging techniques can help identify early warning signs of this in the "Science Report" magazine online editionAlzheimer's disease is a degenerative disease of the nervous system, its risk with age is significantly increasedNeurons and synapses loss caused by the disease can lead to cognitive impairment and dementia, affecting the quality of life of patientsCurrently, the diagnosis of Alzheimer's disease are in decline after a patient begins to show symptoms of cognitive, diagnostic tools mainly magnetic resonance imaging and positron emission tomography and costlyIf you can find a biomarker can be used as early warning signals of the disease, the diagnosis of diseaseearly, can prevent development of the disease through early intervention drugs, exercise, etc., to improve the quality of life of patientsMany researchers conducting research in this area, and the retina is considered such a study can provide objective biomarkersBecause studies have shown that Alzheimer's disease can cause retinal structural changes, most notably the top will lead to thinning of the retinaThe, Duke University researchers developed a multi-mode coherent imaging, optical coherence tomography (OCT) combined with a low angle-resolved coherent interference methodWith this technique, researchers to obtain the thickness of each layer of the retina and configuration information not available OCT aloneThey Alzheimer's disease by studying mice found that diseased mice retinas in the top-most significantly thinner, its neurons exhibited changes in the structure of the textureResearchers believe that these changes in tissue texture features can be used as an early biomarker of Alzheimer's diseaseresearchers noted, early detection of Alzheimer's disease biomarkers facilitate early intervention for the disease, slowing the rate of cognitive decline in patients Their data indicate that retinal changes the texture structure having potential as an early biomarker for Alzheimer's disease, and they developed imaging system provides a unique combination of analysis, detection of retinal pathology will be more straightforward (A Biovalley Bioon.com)
