| Outline of Final Research Achievements |
Recently developed multiscale entropy analysis, which has underpinned aberrant functional connectivity in mental disorders, was introduced to explore changes in EEG complexity occurring with ECT in mental disorders.Depression patients demonstrated a decrease in EEG complexity, especially at higher frequencies. This decrease was associated with improvement of depressive symptoms. In ASD patient, along with ECT, the frontocentral region showed decreased EEG complexity, whereas the occipital region expressed an increase. Furthermore, these changes were associated with clinical improvement associated with the elevation of BDNF.
Multiscale entropy analysis might be a useful analytical method to elucidate neurophysiological mechanisms and evaluate the therapeutic efficacy of ECT in mental disorders.
