- 采用了一种支持向量机器与顺序向前选择 (SVM-SFS) 进行群体歧视.
主要成果:
- 确定了四个微态和四个f-PC区分组.
- 与HC相比,ADHD持久患者表现出长时间的微状态C持续时间,高达功率和降低的α幅度 (A1,A2).
- 转发者显示微状态C持续时间/覆盖率增加,三角形活性降低,α幅度改变 (A1完整,A2减少).

59
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....

89
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.
