Clinically altered brain activity may not look like aged brain activity: Implications for brain‐age modeling and biomarker strategies
Abstract INTRODUCTION Brain‐age gap (BAG), the difference between predicted age and chronological age, is studied as a biomarker for the natural progression of neurodegeneration. The BAG captures brain atrophy as measured with structural magnetic resonance imaging (MRI). Electroencephalography (EEG) has also been explo...
