Mega‐Analysis of Oscillatory and Aperiodic Resting‐State EEG Alterations in Neurodegenerative Diseases

Harmonization mitigates batch effects in the rsEEG posterior power spectrum. LBD is characterized by pronounced oscillatory frequency slowing and increased aperiodic activity, while AD displays both oscillatory and aperiodic abnormalities with smaller effect sizes.

Abstract

Harmonization mitigates batch effects in the rsEEG posterior power spectrum. LBD is characterized by pronounced oscillatory frequency slowing and increased aperiodic activity, while AD displays both oscillatory and aperiodic abnormalities with smaller effect sizes.
