Facial Emotion Recognition Deficits and EEG Alterations in Mild Behavioral Impairment

In this clinic-based SCD/MCI cohort, MBI was associated with greater functional impairment and depressive symptom burden, selective FER deficits-particularly in affect selection-and distinct resting-state EEG spectral and connectivity patterns. These findings suggest that socio-emotional measures and EEG markers may provide complementary information for characterizing neurobehavioral alterations associated with MBI, although interpretations should remain cautious given the cross-sectional design and methodological constraints of automated EEG analyses.
