Resumen de Alzheimer's AI can spot early changes
Artificial intelligence can identify changes in the brains of people likely to get Alzheimer's almost a decade before doctors can diagnose the disease from symptoms alone. To enable earlier diagnosis, Marianna La Rocca at the University of Bari in Italy and her colleagues developed a machine learning algorithm to discern structural changes in the brain caused by Alzheimer's disease. First, they trained the algorithm using 67 MRI scans, 38 of which were from people who had Alzheimer's and 29 from those who didn't. This shows that the algorithm could identify changes in the brain that lead to Alzheimer's almost a decade before clinical symptoms appear.
