New diagnosis for Alzheimer's
In the largest and most conclusive study of its kind , researchers have analysed blood samples to create a novel and non-invasive way of helping to diagnose Alzheimer's disease and distinguishing between different types of neurodegenerative disorders. Following this breakthrough discovery, Alzheimer's sufferers may now have an additional test to improve the accuracy of diagnosis in order to better tailor appropriate treatment. The research also offers a valuable opportunity to monitor the progression of the disease. The international study in the Proceedings of the National Academy of Sciences USA used sensor-based technology with a diamond core to analyse approximately 550 blood samples. By passing light through the diamond and observing its interactions with the blood plasma, researchers were able to identify specific chemical bonds within the blood. This biochemical data was used to compare blood samples from cases of Alzheimer's disease and other neurodegen...
