Discovery of the day
A novel machine learning approach effectively classifies tau pathology status in amyloid-positive cohorts using structural MRI and amyloid PET features, offering a surrogate for costly tau PET imaging. The logistic regression model achieved an area under the curve of 0.92 in both internal and external validation, with combined accuracy, sensitivity, and specificity of 85%, 83%, and 85%, respectively, across three independent datasets. This method demonstrates clinical actionability by predicting faster progression to Alzheimer’s disease in MCI patients with predicted tau positivity, aligning with the need for multimodal biomarker integration and accessible diagnostic screening tools that correlate imaging data with disease progression.
