- 精神病学是一个精神病学.
- 神经成像是一种神经成像.
背景情况:
- 海马和桃体是对记忆,情绪和压力至关重要的边缘结构.
- 边缘结构和心理社会功能之间的关系,特别是早期环境风险,在精神分裂症谱系障碍 (SSD) 和情绪障碍 (MOD) 中尚不清楚.
研究的目的:
- 研究海马和杏仁体结构与SSD和MOD中的心理社会功能之间的关联.
- 检查早期环境风险因素对这些关联的缓和作用.
主要方法:
- 从患有SSD (n=64),MOD (n=66) 和健康对照组 (HC,n=46) 的患者获得结构性3T核磁共振扫描.
- 使用FreeSurfer进行了海马子和杏仁核的细分.
- 用个人和社会绩效尺度 (PSP) 评估心理社会功能,将童年虐待,城市成长和移民背景作为潜在的调节因素.
主要成果:
- 与HC相比,SSD患者的左海马子场体积减少.
- 在SSD中,PSP得分与左海马体,尾部和分子层体积相关,受到情绪虐待和忽视的调节.
- 对于其他环境风险因素,没有发现显著的相互作用.
- 在MOD中,只有左侧膜体积与HC不同,与PSP得分无关,没有显著的相互作用.
结论:
- 生命早期的情绪逆境缓和了SSD中心理社会功能和海马体结构之间的联系.
- 在MOD中没有观察到这种缓解效应.
- 情绪创伤史对于理解SSD的功能结果至关重要.

Psychological and Sociocultural Causes of Schizophrenia
468
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Biological Causes of Schizophrenia
491
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
