| Summary: | Purpose This study aimed to calculate and analyze the differences in electroencephalogram (EEG) between major depression disorder (MDD) patients and healthy controls using the method of brainwave music to provide evidence of physiological parameters for clinical diagnosis of MDD. Methods We translated the 5-minute resting EEG data of 20 MDD patients and 20 healthy controls, which were collected by Peking University Sixth Hospital, into brainwave music; and calculated the pitch, volume, duration and corresponding scaling exponents to analyze the differences between MDD patients and healthy people. Then combined the analysis methods of nonlinear dynamics and brain network structure to verify the validity of the proposed method. Results The pitch, volume, and Lemple-Ziv complexity (LZC) in the frontal lobe of MDD patients were higher than those of healthy people. In the central, occipital, and temporal regions of the left hemisphere, the scaling exponents, degrees, and clustering coefficient of MDD patients were lower than those of healthy people (P < 0.05). Conclusions This study has shown that brainwave music analysis can reflect the differences between MDD patients and healthy controls from a new perspective, and these differences may provide a scientific basis for the clinical diagnosis and brainwave music therapy of MDD.
