Eyes Reveal Early Alzheimer's Disease

A Northwestern Medicine study published in PLOS ONE suggests the noninvasive detection of reduced blood capillaries in the back of the eye could signal cognitive impairment preceding Alzheimer's, reports Medical Xpress . The team used an infrared camera to identify the vascular changes. "Once our results are validated, this approach could potentially provide an additional type of biomarker to identify individuals at high risk of progressing to Alzheimer's," said Northwestern Professor Amani Fawzi. "These individuals can then be followed more closely and could be prime candidates for new therapies aimed at slowing down the progression of the disease or preventing the onset of the dementia associated with Alzheimer's."
