Outline of Final Research Achievements

As a mechanism that increases the risk of cognitive decline due to chronic renal failure, we hypothesized that decrease of neurogenesis in the brain of hippocampus might be involved in cognitive decline due to chronic renal failure. In the rat model of chronic renal failure, cognitive function were decreased and depressive symptoms were observed. As a result of histological analysis, microglia, involved in inflammation, were activated and neurogenesis was suppressed in the hippocampus, related to memory and learning. Uremic toxins were increased in plasma and kidney, but hardly detected in brain. It is necessary to find other uremic toxins which accumulate in the brain.

Academic Significance and Societal Importance of the Research Achievements

慢性腎不全による透析患者は、年々増加し、支出される医療費の増加が社会問題となっている。また、慢性腎不全による死亡は死亡原因の第7位であり、国民病となっている。慢性腎不全の主要な原因疾患は糖尿病であるが、加齢によっても進行する。透析は社会活動が制限され、腎機能の低下による認知機能低下するため健康寿命を短縮している要因である。本研究は、慢性腎不全患者の健康寿命を延伸するための一助となる可能性のある研究である。
