概括
脑图显示了注意力缺陷多动症 (ADHD) 和伴随疾病的儿童的大脑结构差异. 这些发现与注意力缺失的严重程度有关,
科学领域:
- 神经科学
- 发展心理学
- 医学成像
背景情况:
- 注意缺陷多动症 (ADHD) 是一种常见的神经发育障碍,经常与抑郁症,图雷特综合征 (TS) 和自闭症谱系障碍 (ASD) 等其他疾病同时发生.
- 由于ADHD与这些疾病的并发症使得查,诊断和治疗变得复杂.
- 了解ADHD的神经发育变异及其并发症对于有效的干预至关重要.
研究的目的:
- 使用大数据导出的大脑图表作为评估ADHD儿童大脑发育的客观标准.
- 为了比较纯ADHD和伴随疾病 (抑郁症,TS,ASD) 的儿童之间的区域大脑发育差异.
- 探索特定结构性脑部偏差与ADHD症状严重程度之间的相关性.
主要方法:
- 这是一项以人口为基础的大型横截面研究,
- 使用大数据衍生脑图进行客观的脑发育评估.
- 通过规范性脑图建模,研究了区域大脑发育差异和结构偏差与临床症状之间的关联.
主要成果:
- 在特定的大脑区域 (左状环,中状环) 观察到皮层厚度的显著差异.
- 在ADHD+TS群体中,脑部区域的偏差最为严重.
- 在ADHD+TS和ADHD+抑郁症组之间,结构性偏差,特别是在左中额头中,显示出显著的差异,并且与注意力不集中和对立性挑性障碍的严重程度有负相关性.
结论:
- 脑图有效地突出了ADHD和伴随疾病的结构差异.
- 这些变化有助于预测注意力缺失症状的严重程度.
- 这些发现有助于人们更好地理解ADHD的神经生物学,

Attention-Deficit/Hyperactivity Disorder
289
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

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
