精神分裂症与许多关键大脑系统的结构和功能变化有关,包括分别涉及工作记忆和陈述性记忆的前额叶和内侧颞叶区域。成像技术为这些变化提供了一个无与伦比的窗口,允许在疾病的发病前和发病后阶段以及与大脑发育的关键时期进行重复评估。在这里,我们回顾了精神分裂症的结构和功能神经影像学研究的最新方向。从这项工作中出现的观点是,精神分裂症从根本上说是一种神经连接中断的疾病,其来源似乎是影响产前和青春期大脑发育的遗传和环境风险因素。
Schizophrenia is associated with changes in the structure and functioning of a number of key brain systems, including prefrontal and medial temporal lobe regions involved in working memory and declarative memory, respectively. Imaging techniques provide an unparalleled window into these changes, allowing repeated assessments across pre- and post-onset stages of the disorder and in relation to critical periods of brain development. Here we review recent directions in structural and functional neuroimaging research on schizophrenia. The view emerging from this work is that schizophrenia is fundamentally a disorder of disrupted neural connectivity, the sources of which appear to be genetic and environmental risk factors influencing brain development both prenatally and during adolescence.
