Impairment in recognition of emotional facial expressions in Alzheimer's disease is represented by EEG theta and alpha responses

Behavioral studies have shown that the recognition of facial expressions may be impaired in patients with Alzheimer's disease (AD). The identification and recognition of a facial expression might be represented by event‐related brain oscillations. The present study aims to analyze EEG event‐related oscillations and determine the electrophysiological indicators of impaired facial expression recognition in AD patients. EEGs of 30 healthy controls...
