New technology can predict Alzheimer's two years before doctors

Artificial intelligence can pick up on symptoms of Alzheimer's disease in brain scans long before doctors or patients. A computer-driven algorithm was able to accurately foresee whether or not a person would develop Alzheimer's disease up to two years before he or she displays symptoms, according to a new study from McGill University. It was correct in its predictions 84% of the time. Researchers are excited for the AI's potential to help choose patients for clinical trials and drugs ahead of the disease's onset that could delay its debilitating effects. "If you can tell from a group of individuals who is the one that will develop the disease, one can better test new medications that could be capable or preventing the disease," Dr. Pedro Rosa-Neto, a study co-author, told Live Science.
