Artificial intelligence can predict Alzheimer's years before doctors

Artificial intelligence can predict Alzheimer's at least two years in advance, according to new research. The technique works by spotting hidden patterns in the data and learning who is most at risk. A study involving more than 15,300 people found it was 92 percent accurate. The neural network would change the way dementia is diagnosed - helping doctors detect it sooner. Treatments would start much earlier.
