Outline of Final Research Achievements

Twenty-five cases were registered. No adverse event was admitted. Increasing the hippocampal volume after electroconvulsive therapy might be specific and play a central role in the treatment mechanism of electroconvulsive therapy. Like previous studies, we also identified white matter changes in diffusion tensor imaging and functional connectivity changes on resting-state functional MRI.

Academic Significance and Societal Importance of the Research Achievements

うつ病は生活の質に与える影響が大きい疾病とされている。うつ病に対しては認知行動療法や薬物療法が行われるが、治療反応が示されなかった症例は治療抵抗性うつ病とされ、電気けいれん療法の適応とされる。電気けいれん療法の作用機序において海馬容積増大の関与が示唆されたことは、難治性うつ病の回復過程の神経学的基盤の解明に寄与したと考えられる。
