概括
高频跨脑随机噪声刺激 (tRNS) 与认知训练 (CT) 结合,显著改善了儿童注意力缺陷/多动症 (ADHD) 症状. 这些临床改善和对大脑活动的影响在随访期间持续存在.
科学领域:
- 神经科学是一个神经科学.
- 儿科神经学 儿科神经学
- 精神病学是一个精神病学.
背景情况:
- 注意缺陷/多动障碍 (ADHD) 是一种常见的儿童神经发育障碍,具有持续的症状和认知缺陷.
- 非侵入性脑刺激技术正在被探索为ADHD的潜在治疗干预措施.
- 高频跨骨随机噪声刺激 (tRNS) 是一种新的刺激方法,在神经疾病中具有潜在的应用.
研究的目的:
- 研究tRNS与认知训练 (CT) 结合在改善儿童ADHD症状和神经振荡方面的疗效.
- 评估tRNS + CT对ADHD症状和大脑活动的持久影响.
- 评估tRNS+CT对儿童ADHD睡眠模式和执行功能的影响.
主要方法:
- 一个随机的,双盲的,假的受控试验与23名被诊断患有多动症的未经药物治疗的儿童进行.
- 参与者在特定的前额叶皮层区域接受了tRNS或假刺激,持续2周,与CT一起.
- 休息状态脑电图 (EEG) 和家长报告的ADHD评分尺度用于评估.
主要成果:
- 与虚假组相比,tRNS + CT显著减少了父母报告的多动症症状,随着随访持续改善.
- 在tRNS + CT组中观察到周期性β带宽的减少和静止状态EEG的较低无周期指数.
- 实验组报告了睡眠开始延迟的增加和更频繁的唤醒时间;执行职能没有显著变化.
结论:
- tRNS + CT 表明对儿童的多动症症状有持久的临床益处.
- 这种干预有效调节神经振荡,特别是减少β活性.
- 这些发现表明tRNS + CT是对儿科多动症的有希望的新型干预措施,需要进一步调查.

Blinding
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
Attention-Deficit/Hyperactivity Disorder
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.
