- 检查功能连接模式与家长报告的ADHD症状和执行功能之间的关系.
主要方法:
- 在120名患有AIS (N=31),PVI (N=30) 和典型发育对照 (N=59) 的儿童 (6-19岁) 中测量了休息状态功能连接性.
- 分析采用了背部注意力,前端双相和默认模式网络中的已建立的种子区域.
- 评估了功能连接度量与家长报告的执行功能和ADHD症状之间的关联.
主要成果:
- 与对照组相比,AIS和PVI组的功能连接在半球内和半球间减少.

Attention-Deficit/Hyperactivity Disorder
68
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Information Processing Approach
42
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...
