Alzheimer’s detected by AI 6 years before diagnosis

In a recent study, Jae Ho Sohn and UCSD colleagues used an AI to analyze glucose-monitoring PET scans to detect early-stage Alzheimer’s disease six years before  diagnosis.

The algorithm was trained on PET scans from patients who were eventually diagnosed with  Alzheimer’s disease, MCI, or no disorder. It was able to  identify 92% of patients who developed Alzheimer’s disease in the first test set and 98% in the second test set, 75.8 months before diagnosis on average.v
