Outline of Final Research Achievements

To explore the rehabilitative effects of a high-fat diet on depression, we first confirmed that mice fed a high-fat diet continuously develop depressive-like behaviors. We also confirmed that feeding the mice only at certain times of the day (only at night, since mice are nocturnal) improved depressive-like behavior and that the continuous high-fat diet effectively reduced inflammation in the brain. Furthermore, in a study of post-stroke depression among first-time working-age patients between the ages of 20 and 64, we confirmed that approximately 50% of the patients were depressed.

Academic Significance and Societal Importance of the Research Achievements

現代社会において、「抑うつ」は多くの人々を苦しめている大きな社会的問題です。私たちの研究では、この「抑うつ」が、食生活の乱れと関連していることが解明されつつあり、その病態を調べることにより、何らかのリハビリや食事療法を施すことで、この「抑うつ」を改善させる効果が期待されます。そんな中、今回の研究では、時間制限給餌という限られた時間帯にのみ食事をすることの効果が示されました。今後は、実際に「抑うつ」の症状で苦しんでおられる患者様への効果を検証したいと考えています。
