| Outline of Final Research Achievements |
At the time of post-treatment for depression, higher blood SAP was associated with better cognitive function test (WCST) results, and higher pre-treatment SAP was associated with improved post-treatment cerebral blood flow reduction associated with Alzheimer's disease. These results suggest that SAP may have a protective effect against cognitive impairment and reduced cerebral blood flow in depressed patients. As for REST, higher post-treatment blood REST was associated with better WCST results. This suggests that REST may have a protective effect against cognitive dysfunction in depressed patients. We also found that blood REST levels correlated with blood SAP levels both before and after treatment for depression.

| Academic Significance and Societal Importance of the Research Achievements |
うつ病患者においてSAPとRESTがともに認知機能や脳血流を改善する可能性が示唆された．さらに，SAPとRESTが互いに相関すること，さらに共通してWCSTと正の相関を示したことは興味深く，SAPとRESTの間にどのような関係があるかについてはさらなる研究が必要である．今後研究を推進することでうつ病から認知症への進展の予防や認知症の治療に関する新たな知見が得られる可能性がある．
