概括
自闭症谱系障碍 (ASD) 与大脑连接的改变有关. 这一元分析揭示了自闭症患者在默认模式网络 (DMN) 和腹部注意网络 (VAN) 中的一致性功能障碍.
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.
- 医疗成像医学成像
背景情况:
- 自闭症谱系障碍 (ASD) 与大脑通信中断有关,特别是在静止状态功能连接 (rsFC) 中.
- 之前关于RsFC在ASD中的发现缺乏一致性,需要进行全面的分析.
- 了解这些神经差异对于诊断和治疗ASD至关重要.
研究的目的:
- 与对照人群相比,系统地分析和元分析自闭症谱系障碍 (ASD) 患者的静止状态功能连接 (rsFC).
- 调查多种种子级别的rsFC差异,包括功能网络和特定的大脑区域.
- 在ASD中识别大脑网络功能障碍的一致模式.
主要方法:
- 在ASD中基于种子的全脑rsFC研究的系统审查和元分析.
- 搜索了PubMed,Embase和PsycINFO数据库,从创建开始到2023年12月20日.
- 包括26项研究,包括709名自闭症患者和705名对照人群,使用基于种子的d绘图软件分析种子和峰值效应坐标.
主要成果:
- 在前部区域,在腹部注意网络 (VAN) 中的右侧中间带带状回形 (MCG) 和在默认模式网络 (DMN) 中的中间左上额头回形中发现了显著的rsFC差异.
- 在VAN中,MCG显示了强大的效应大小 (g = -0.51).
- 在中部左上额头环中,在DMN中显示出显著的效应大小 (g = -0.42).
结论:
- 这些发现支持了自闭症患者默认模式网络 (DMN) 功能障碍的假设.
- 这一元分析为ASD中腹部注意力网络 (VAN) 功能障碍提供了新的证据.

Autism Spectrum Disorder
962
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling in Therapy
378
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
