Outline of Final Research Achievements

In this study, we focused on hemorrhagic stroke and explored therapeutic targets that could improve functional prognosis. In a mouse model of subarachnoid hemorrhage, we found that decreased cerebral blood flow in the acute phase after subarachnoid hemorrhage contributes to neurological function and cognitive dysfunction in the subacute phase. We reported that nafamostat, an existing drug, improves neurological findings after subarachnoid hemorrhage.

Free Research Field

出血性脳卒中, 虚血性脳卒中

Academic Significance and Societal Importance of the Research Achievements

出血性脳卒中はは全脳卒中の10-15%程度を占める疾患であるが、半年後の日常生活自立率は約20%とされ、罹患者のみならずその家族の負担も大きい。発症後の症状の緩和・改善は罹患者・家族の負担軽減のみならず、医療経済にも大きく貢献できると考える。今回くも膜下出血後の脳血流低下が予後増悪に関与する事、ナファモスタットが新規治療薬の可能性がある事を報告した。出血性脳卒中後に生じる神経障害への治療法は皆無である現在において、直接的な神経傷害の軽減につながる報告となったと言える。
