| Outline of Final Research Achievements |
From August 2013, rTMS was started for patients with major depression, and by March 2020, rTMS was performed for 32 cases. Based on the above studies,Although rTMS resulted in partial improvement of frontal lobe dysfunction as well as white matter integrity, we found no correlation between improved frontal lobe dysfunction and improved white matter integrity in treatment-resistant depression patients. In addition, there was no significant change in inflammatory cytokines alone (IL-1β, IL-6, TNF-α) before and after rTMS treatment, but partial changes in cognitive function and changes in IL-1β were significantly correlated.

| Academic Significance and Societal Importance of the Research Achievements |
rTMSによる治療抵抗性うつ病患者の大脳白質構造を反映する異方分画性（FA）と認知機能との関連を研究した報告及び認知機能と炎症性サイトカインとの関連を調べた報告はこれまでになく、今回の結果は貴重である。特に後者の結果から、rTMSによる治療抵抗性うつ病の認知機能障害の改善に血清IL-1βの低下が何らかの形で関与している可能性が示唆された。
