A team of researchers at the University of Cambridge, in collaboration with the Alan Turing Institute, constructed sophisticated machine learning tools capable of detecting dementia in its early stages. Published in the journal NeuroImage: Clinical, researchers took brain scans of numerous patients who subsequently developed a neurodegenerative illness, like Alzheimer's disease. With their machine learning algorithm, researchers were able to spot structural changes in the brain. According to the study, the AI-based algorithm was more than 80 percent accurate in predicting the onset of dementia among the participants. The algorithm also predicted the speed at which cognitive function declined.
