Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

50
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....

科学领域:

  • 神经成像是一种神经成像.
  • 发育神经科学的发展神经科学.
  • 儿童心理学 儿童心理学

背景情况:

  • 在磁共振成像 (MRI) 过程中头部运动是神经成像研究中的重要混因素.
  • 患有神经发育障碍的个人,如注意力缺陷多动症 (ADHD) 障碍,通常表现出头部运动增加.
  • 了解头部运动轨迹对于准确分析儿童大脑发育至关重要.

研究的目的:

  • 研究ADHD和没有ADHD的儿童头部运动的发育轨迹.
  • 为了比较缓和和持续的ADHD儿童之间的头部运动轨迹.
  • 在不同诊断群体中识别与年龄相关的头部运动变化.

主要方法:

  • 从105名ADHD儿童和84名9-14岁的对照组中收集了纵向扩散和静止状态功能性MRI扫描.
  • 扫描器内头部运动是用框架向上的位移量化的.
  • 用通用添加混合建模来分析纵向轨迹.

主要成果:

  • 随着年龄的增长,头部运动在扩散和静止状态功能性MRI中显著下降 (p < .001).
  • 患有ADHD的儿童的头部运动明显大于对照组的年龄范围 (p = .036对于扩散MRI,p = .004对于功能MRI).
  • 与对照组相比,在缓解ADHD的儿童中,头部运动持续升高 (扩散MRI的p = .020,功能MRI的p = .011).

结论:

  • 头部运动与儿童的发育年龄密切相关,无论ADHD的诊断如何.
  • 随着年龄的增长,头部运动的变化速度在缓解和持续的ADHD组之间没有差异.
  • 这些发现强调了在神经发育研究中考虑头部运动的重要性,并表明一些与ADHD相关的行为表现可能会持续到临床缓解之后.
