概括
患有ADHD的学前儿童在脑干中表现出听觉处理异常,通过语音听觉脑干反应 (语音-ABR) 确定. 语音ABR是一种可靠的工具,用于评估ADHD的听觉处理,不受智商的影响.
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
- 听力学 听力学是指听力学.
背景情况:
- 注意缺陷/多动障碍 (ADHD) 是一种常见的神经发育障碍,影响学龄前儿童.
- 听觉处理 (AP) 困难可能会影响ADHD儿童的语言和学习.
- 语音听觉脑干反应 (语音-ABR) 提供了关于中央听觉神经系统处理语音信号的见解.
研究的目的:
- 通过使用语音-ABR. 调查 ADHD 的学龄前儿童的听觉处理 (AP) 特性.
- 为了确定语音ABR是否可以可靠地评估ADHD儿童的AP,独立于认知因素.
主要方法:
- 在84名患有ADHD的学龄前儿童和84名典型发育 (TD) 对照者 (年龄为4-6岁) 上进行了语音ABR测试.
- 进行认知评估 (WIPPSI-IV/WISC-IV) 和持续性表现测试.
- 多重线性回归分析被用于识别语音-ABR延迟的预测因素.
主要成果:
- 与TD儿童相比,患有ADHD的儿童表现出明显更长的语音-ABR延迟 (波V,A,D).
- ADHD诊断,不是全面的智商系数,显著影响了语音-ABR波延迟.
- 语音-ABR短暂反应 (V,A) 是ADHD的显著预测因素.
结论:
- 患有ADHD的学龄前儿童在中央听觉神经系统中表现出异常的语音信号的听觉处理.
- 语音ABR是评估ADHD儿童AP的可靠措施,不受认知或注意因素的影响.
- 使用语音ABR对AP异常的早期评估是针对性ADHD干预的建议.

51
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....

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.
