精神分裂症患者在大脑结构中表现出更大的变化,影响认知功能. 皮层相似性的偏差与精神分裂症患者的智力低下相关.
科学领域:
- 神经成像是一种神经成像.
- 精神病学是一个精神病学.
- 认知神经科学 认知神经科学
背景情况:
- 精神分裂症 (SCZ) 与大脑皮层结构异常有关,但临床相关性尚不清楚.
- 之前的研究集中在群体差异上,忽视了个体间的差异.
- 现在的研究正在探索皮层形态学异质性和临床异质性之间的联系.
研究的目的:
- 研究精神分裂症中大脑皮层结构的个体间差异.
- 检查结构变化和认知功能之间的关联.
主要方法:
- 利用了来自695名SCZ患者和420名健康对照者的神经影像数据.
- 分析的表面积,灰质体积,厚度和局部化指数.
- 计算的变化系数 (CV) 和基于人的相似性指数 (PBSI);评估的认知关联.
主要成果:
- 与对照组相比,SCZ患者表现出更高的CV表面积和皮质厚度.
- 在SCZ患者中,在皮层测量中观察到较低的PBSI得分.
- 灰质体积和整体皮质测量的PBSI得分与智商相关;偏差的PBSI得分表明智商较低.
结论:
- 在SCZ患者的大脑皮层显示区域和全球结构变异性增加.
- 偏差的皮层结构相似性概况与SCZ的一般智力下降有关.
