在整个精神分裂症的频谱中都存在thalamic核体积的减少. 较低的中介性乳头核体积与患有精神病和精神分裂症的个体面临危险的认知缺陷有关.
科学领域:
- 神经成像是一种神经成像.
- 精神病学是一种精神病学.
- 认知神经科学 认知神经科学
背景情况:
- 异常的乳头核体积与精神分裂症的认知障碍有关.
- 目前尚不清楚这些胸膜异常是否延伸到精神分裂症谱中.
研究的目的:
- 为了研究整个精神分裂症谱的thalamic核体积模式.
- 检查乳头核体积与认知症状之间的关联.
主要方法:
- 从健康对照组,有风险的精神状态 (ARMS) 个体,第一发精神病 (FEP) 个体和精神分裂症患者的T1加权的大脑MRI被使用FreeSurfer体积分析.
- 估计了六个核组的thalamic核体积.
- 线性回归模型评估了群体差异和与临床症状的关联,控制共变量.
主要成果:
- 在整个精神分裂症谱中,在中间和侧面的乳头核中观察到显著的体积变化.
- 与整个频谱的对照组相比,中间核显示出一致的体积减少.
- 较低的中间核体积与ARMS和精神分裂症患者的认知缺陷有关.
结论:
- 显著的乳头核体积减少是精神分裂症谱的特征.
- 中部乳头核异常特别与早期认知缺陷和已确定的精神分裂症有关.
- 这些发现表明,精神分裂症中thalamic核异常的渐进性轨迹.
