发育性创伤 (DT) 通过改变大脑结构与精神病体验 (PE) 有关. DT患者的杏仁体体积减少可能会增加PES风险,这表明了潜在的预防策略.
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.
- 发展心理学 发展心理学
背景情况:
- 发育创伤 (DT) 越来越多地与精神病体验 (PE) 相关.
- 连接DT和PEs的神经生物学机制尚未得到充分理解.
- 涉及威胁和记忆处理的大脑区域也会受到影响.
研究的目的:
- 为了研究DT对大脑结构的影响.
- 为了检查结构性大脑改变在DT-PEs协会中的作用.
- 探索可能的神经生物学途径,将DT与PEs联系起来.
主要方法:
- 利用了来自阿文长度研究父母和儿童 (ALSPAC) 队列的数据.
- 包括419名参与者,他们拥有DT (0-17岁),PEs (18岁) 和成人大脑体积的数据.
- 分析了威胁和记忆处理区域的结构体积.
主要成果:
- DT暴露与PEs的概率增加相关 (OR=1.64).
- 累积的DT暴露显示了对PEs的剂量反应效应.
- DT与左桃体体积的减少有关,也显示了累积效应.
- 减少左桃体体积与更高的PEs概率有关.
结论:
- 威胁和记忆处理区域的结构变化可能会调解DT和PE之间的联系.
- 这些发现支持神经生物学理论的创伤后精神病的发展.
- 这些结果表明精神病预防策略的潜在目标.
