Outline of Research at the Start

統合失調症は全人口の約1%が罹患し、陽性症状、陰性症状、及び認知機能障害を特徴とする多彩な精神症状を呈する。多くは思春期に発症し慢性・進行性経過をたどる。統合失調症患者の多くは、疾病経過とともに陽性症状は減弱する反面、いわゆる陰性症状とよばれる認知機能障害が進行性に優勢になり、社会機能の低下をきたす。実臨床では、高齢のいわゆる慢性化した統合失調症患者の社会復帰は困難であり、治療的観点からも病因病態の明確化とその治療戦略がのぞまれている。本研究では、脳の磁気共鳴画像(magnetic resonance imaging: MRI)を用いて、加齢に伴う脳構造変化とそれに伴う機能の変化を捉える。

Outline of Final Research Achievements

In this study, we analyzed resting-state fMRI data from patients with schizophrenia and healthy controls and used a novel network measure, the functional connectivity overlap ratio (FCOR) (Bagarinao,et al., 2020), to examine connector hub impairment in schizophrenia. We have demonstrated that connector hub regions, including those in the cerebellum, thalamus, and other subcortical regions, are severely impaired in patients with schizophrenia.

Academic Significance and Societal Importance of the Research Achievements

統合失調症の多くは思春期に発症し慢性・進行性経過をたどる。実臨床では、 高齢のいわゆる慢性化した統合失調症患者の社会復帰は困難であり、病因病態の明確化とその治療戦略が望まれている。脳の磁気共鳴画像(magnetic resonance imaging: MRI)を用いた研究から、疾病の経過とともに経時的に 脳容積が減少することが報告されているが、脳機能ないし神経回路の観点からは十分な検証がされていない。今回、新規ネットワーク指標を用いて統合失調症における connector hubの障害を示した。さらに、加齢に伴う障害の変化を捉えることで、加齢に伴う脳神経回路病態を解明することができる。
