Artificial intelligence can detect Alzheimer's disease in brain scans 6 years before a clinical diagnosis by recognizing changes in brain glucose levels which are very subtle and otherwise difficult to see.
The algorithm performed with flying colors. It correctly identified 92 percent of patients who developed Alzheimer’s disease in the first test set and 98 percent in the second test set. What’s more, it made these correct predictions on average 75.8 months – a little more than six years – before the patient received their final diagnosis.
