最近发病的精神病和抑郁症中的无情可能与炎症和大脑连接的改变有关. 识别这种跨诊断亚型为新出现的精神障碍提供了新的治疗点.
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.
- 免疫学 免疫学 免疫学
背景情况:
- 慢性低度炎症是精神障碍的跨诊断因素,与无情感和大脑变化有关.
- 很少有研究探讨了近期发病的精神病和抑郁症中的炎症标志物,特别是关于安赫多尼亚的研究.
- 这项研究调查了最近出现精神病或抑郁症的年轻人中与无情相关的炎症信号和大脑功能.
研究的目的:
- 在近期发病的精神病和抑郁症中,识别与无情相关的炎症信号.
- 检查这些人群中与无症相关的功能性大脑连接模式.
- 为了探索安赫多尼亚作为潜在的跨诊断目标.
主要方法:
- 利用休息状态功能磁共振成像 (fMRI) 并测量了108名患有近期精神病或抑郁症的参与者的炎症标志物.
- 采用先进的多式联机机器学习来开发基于炎症标志物和功能连接的参与者分类模型.
- 分析了100个感兴趣的皮质区域的时间序列数据,使用Schaefer地图.
主要成果:
- 一个炎症标记模型准确地分类了无享乐和正常享乐组,精度为63.9% (AUC=0.61).
- 功能连接模型的准确性较低,为55.2% (AUC=0.57).
- 关键的炎症标志物区分组包括更高的互白素-6,S100B和互白素-1受体对抗剂,以及更低的干扰素-,以及改变的前皮和后皮带连接.
结论:
- 在近期发病的精神病和抑郁症中发现了一种独特的无情性亚型,其特征是特定的炎症特征和功能连接模式.
- 这些发现表明,炎症和大脑连接对于理解新出现的精神障碍中的无意识症至关重要.
- 安赫多尼亚是一个有希望的跨诊断治疗目标,用于心理健康状况的早期干预.
