Mean EEG feature values significantly correlated with AD CSF biomarkers

This dataset contains raw, patient-level mean EEG feature values recorded during sleep from individuals diagnosed with Alzheimer’s disease (AD). EEG features were extracted from four electrodes (C3–A2, C4–A1, F4–A1, O2–A1) across four sleep stages (N1, N2, N3, and REM) using 2-minute signal windows with 25% overlap. For each patient, feature values were averaged across windows. Only EEG features showing significant correlations with cerebrospinal fluid (CSF) Alzheimer’s disease biomarkers were retained. The considered CSF biomarkers are total tau (t-tau), phosphorylated tau (p-tau), and beta-amyloid (Aβ).
