精神病中炎症升高与大脑网络连接性降低和认知功能较差有关. 这项研究揭示了炎症如何破坏大脑网络组织,影响精神病谱系障碍的认知.
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.
- 炎症研究 炎症研究
背景情况:
- 患有精神病的患者经常表现出认知缺陷和神经解剖学变化,特别是在高度炎症的子组.
- 通过IL-6和C反应蛋白等细胞因子评估的系统性炎症被假设会影响静止状态的功能连接性,但其认知含义尚不清楚.
研究的目的:
- 调查精神病谱系障碍中升高的外周炎症子组和静止状态功能网络之间的关系.
- 确定这些网络变化如何与精神病患者的认知表现相关.
主要方法:
- 休息状态的fMRI和血清细胞因子数据从精神病患者和健康对照组中收集,分层分为炎症子组.
- 独立组件分析确定了九个静态网络; 评估了功能和多层连接.
- 用精神分裂症认知简要评估来评估认知功能.
主要成果:
- 高炎症精神病子组与低炎症组相比,显示前置默认模式网络 (DMNa) 连接性减少.
- 在高度炎症的组中,DMNa和前端对象网络之间的互联网连接性减少了.
- 网络组织,包括积极和消极连接集群和多重参与,在高炎症子组中受损,与较差的认知分数相关.
结论:
- 外周炎症特征与精神病中大脑网络功能受损有关.
- 炎症可能会损害大脑调节休息状态网络之间的协同激活和抑制的能力,导致认知缺陷.
