概括
自闭症谱系障碍 (ASD) 和注意力缺陷/多动症障碍 (ADHD) 有共同的特征. 一项研究发现,ASD和ADHD儿童的视觉唤起潜能 (VEP) 中的P1振幅降低,这表明有不同的大脑活动模式.
科学领域:
- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 临床心理学 临床心理学
背景情况:
- 自闭症谱系障碍 (ASD) 和注意力缺陷/多动症障碍 (ADHD) 呈现出显著的症状重叠.
- 在这些神经发育条件下,识别跨诊断标记对子组分层至关重要.
- 了解不同的神经生理模式可以帮助差异诊断和有针对性的干预措施.
研究的目的:
- 为了比较ASD儿童的视觉唤起潜力 (VEPs),ASD和ADHD同时发生的ASD和ADHD (ASD+ADHD) 和神经类型对照 (NTC).
- 调查P1事件相关的潜在振幅作为潜在的跨诊断标记.
- 识别与同时出现的ASD和ADHD相关的大脑活动的独特模式.
主要方法:
- 使用脑电图 (EEG) 来记录大脑活动.
- 参与者 (30个ASD,17个ASD+ADHD,21个NTC) 被动地观看了一个模式逆转的视觉刺激.
- 在VEP的P1组件的平均振幅从中线尾通道中提取.
主要成果:
- 与只有ASD组相比,ASD+ADHD组的P1平均幅度降低了.
- 与神经型儿童 (NTC) 组相比,ASD+ADHD组也显示了P1平均幅度的减少.
- 这些发现表明,ASD和ADHD同时发生的儿童具有明显的神经生理学特征.
结论:
- 在VEP中减少的P1振幅可以作为一个跨诊断标记,用于区分ASD儿童的子组.
- 这些发现突出了自闭症儿童与伴随性ADHD的独特大脑活动模式.
- 需要进一步的研究来探索VEP在神经发育障碍中的临床实用性.

133
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....

167
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.
