Artificial Intelligence Predicts Your Risk of Alzheimer's with 99% Accuracy - The Science Tech

An artificial intelligence (AI) system has been developed that can identify early signs of Alzheimer's disease (AD) with over 99 percent accuracy. By evaluating brain scans of older adults, the algorithm can pick out subtle changes that often occur before diagnosis, allowing doctors to treat high-risk individuals early. In the journal Diagnostics, the study authors describe how AI successfully recognizes signs of Mild Cognitive Impairment, considered an intermediate stage between normal aging and the expected cognitive decline associated with Alzheimer's. Although MCI typically does not produce obvious symptoms, it is associated with changes in certain brain regions that can be detected on functioning magnetic resonance imaging (MRI) scans. However, manually searching for these changes is difficult.
