  "abstract": "Introduction\n\nEarly identification of amyloid-beta (Aβ) pathology is essential for timely intervention in Alzheimer's disease (AD), as Aβ accumulation precedes clinical symptoms by years.Methods\n\nWe predicted positron emission tomography (PET) -defined Aβ status in cognitively normal individuals using non-invasive resting-state dry electroencephalography (EEG). Brain effective and functional connectivity were quantified to characterize dynamic information transfer between regions. Features derived from dynamic brain connectivity were used to train machine learning models for Aβ classification.Results\n\nEEG-based models can predict amyloid positivity with accuracy comparable to, or in some cases exceeding, that of plasma p-tau217 and previously reported predictors based on cognitive measures, demographics, and health factors, depending on the model.Discussion\n\nBeyond near real-time Aβ inference, the framework identifies the most affected brain regions and connections associated with neurodegeneration, offering complementary information to blood-based biomarkers and supporting its potential as an affordable tool for early AD detection in primary care and population screening.",
