儿童创伤 (CT) 与精神分裂症中的暴力有关. 这项研究发现,轨道前皮层和其他区域之间的改变大脑功能连接 (FC) 介导了这种关系,这表明了新的干预目标.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 脑部成像 脑部成像
背景情况:
- 精神分裂症与暴力风险增加有关.
- 儿童创伤 (CT) 是精神分裂症谱系障碍中暴力行为的已知危险因素.
- 在精神分裂症中CT暴力联系的神经生物学基础尚不清楚.
研究的目的:
- 调查功能连接 (FC) 在调解CT与精神分裂症患者暴力之间的关系中的作用.
- 识别特定的大脑区域和参与这种关联的网络.
主要方法:
- 招募了55名精神分裂症患者和36名健康对照.
- 利用基于种子的功能连接性分析,专注于轨道前皮层 (ORBinf).
- 进行调解分析,以评估FC在CT暴力关系中的作用.
主要成果:
- 与健康对照组 (HC) 和非暴力精神分裂症患者 (NVSP) 相比,暴力精神分裂症患者 (VSP) 在右ORBinf和右中旋 (MTG) 和右上额头旋之间显示出降低的FC.
- 与NVSP相比,VSP在右ORBinf和右中额头关节之间也表现出较低的FC.
- 调解分析显示,右ORBinf和右MTG之间的FC完全调解了CT与暴力之间的关联.
结论:
- 功能连接的改变,特别是涉及轨道前皮层,与精神分裂症中的暴力有关.
- 这些发现表明,右ORBinf和右MTG之间的FC可能是关键的神经机制,将儿童创伤与暴力联系起来.
- 这些见解可以为儿童创伤和精神分裂症暴力的有针对性的干预措施的开发提供信息.
