Artificial intelligence can predict Alzheimer’s disease two years before doctors can: study

  • 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.
  • Alzheimer’s is the most common form of dementia and clinical trials for drugs to combat the disease must meet a minimum 18 to 24-month run time.
  • “You want to include people who will be progressing from mild cognitive impairment to dementia in the time of the clinical trial,” Rosa-Neto said.
  • Scientists have a tough time predicting the disease on their own through amyloid (a protein that builds up and leads to cognitive damage) PET scans, especially considering that the existence of amyloids in the brain does not necessarily always lead to a dementia diagnosis.
  • The AI technology was then shown the scans of 270 new individuals who had mild cognitive impairments — 43 of whom eventually developed Alzheimer’s — from before they were diagnosed.

Artificial intelligence can pick up on symptoms of Alzheimer’s disease in brain scans long before doctors or patients.
