概括

患有感官过度反应症 (SOR) 的儿童表现出改变白质 (WM) 微观结构,影响他们的体化和情感福祉. 这项神经成像研究揭示了SOR中WM完整性和情感行为之间的关键联系.

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
医疗成像医学成像

背景情况:

感官处理功能障碍 (SPD) 影响儿童的学习和心理健康.
感官过度反应 (SOR),一个常见的SPD,影响至少2.5%的儿童.
有限的研究存在于SOR使用先进的神经成像像像扩散MRI (dMRI).

研究的目的:

研究白质 (WM) 微观结构与SOR儿童情感行为之间的关系.
测试优越的WM完整性是否起到神经塑性补偿机制的作用,以防止在SOR中内化行为.
为了确定受损的WM微观结构是否会增加SOR儿童对体化和抑郁的脆弱性.

主要方法:

在8-12岁的神经发育问题儿童身上使用了3特斯拉MRI与多多带dMRI.
使用感官处理3维评估来评估SOR.
用于扩散张力成像 (DTI) 和神经元定向分散和密度成像 (NODDI) 度量的基于通道的空间统计.

主要成果:

在SOR组中,全球WM分数异构 (FA) 与体化和情绪障碍有负相关性.
患有SOR的儿童显示辐射扩散率 (RD),自由水分数 (FISO) 和体化/情绪障碍之间的正相关性.
在SOR中,中介叶膜和内部囊感官通道受到影响最多,特别是在男孩中.

结论:

WM微观结构与患有SOR的儿童的情感行为有显著的关系.
研究结果表明,SOR中神经可塑性,WM完整性和情绪调节之间存在联系.
需要进一步的研究来探索这些关系,特别是在女孩身上.

关键词:

Attention-Deficit/Hyperactivity Disorder

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....

Socioemotional Development during Infancy

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
