The Eyes Could Be The Window To Alzheimer's Disease, New Study Finds
The study involved 39 people with Alzheimer's disease and 133 participants in a control group. The differences in density were statistically significant after researchers controlled for factors like age, gender, and level of education.
"While a wide range of other proposed blood tests for Alzheimer's disease are being developed, this is the first study to use a machine learning approach to identify sets of proteins in blood that are predictive of a biomarker in spinal fluid", notes the researcher for IBM's genomics research team. That appearance signifies a healthy brain, but in cases of Alzheimer's disease, the blood vessels appear different. In addition, a specific layer of the retina was thinner in those with Alzheimer's. An OCTA scan can even reveal changes in tiny capillaries - most less than half the width of a human hair - before blood vessel changes show up on a brain scan such as an MRI or cerebral angiogram, which highlight only larger blood vessels.
The findings were reported in Ophthalmology Retina, a publication of the American Academy of Ophthalmology.
A new kind of precise and non-invasive imaging called optical coherence tomography angiography (OCTA) has assisted much of the recent research on the eye's connection with Alzheimer's.
Dr Fekrat said: 'Our work is not done.
Early diagnosis will allow researchers to administer them sooner in the disease process which may lead to better results.
