概括
患有努南综合征 (NS) 的儿童表现出类似于自闭症谱系障碍 (ASD) 的大脑网络模式. 这表明RAS-MAPK途径是ASD的关键,NS等遗传模型可以帮助理解ASD病理生理学.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
- 发育儿科 发育儿科
背景情况:
- 自闭症谱系障碍 (ASD) 病理生理学仍然不太清楚,尽管患病率很高.
- RAS-mitogen-activated protein kinase (RAS-MAPK) 途径与ASD有关,并且在诺南综合征 (NS) 中发生变化.
- 患有NS的儿童可以作为一个有价值的遗传模型来研究ASD的神经基础.
研究的目的:
- 为了研究具有NS的儿童表现出ASD症状的功能性大脑网络差异.
- 评估ASD症状预测模型在一个更大,非综合征队列 (ABIDE) 中发展的概括性.
- 探索与NS相关的ASD和特异性ASD之间的共享神经生物学机制.
主要方法:
- 基于Connectome的预测建模 (CPM) 应用于28名NS儿童的fMRI数据 (平均年龄8.24岁).
- 在自闭症脑成像数据交换 (ABIDE) 数据集 (n=352,平均年龄11.0) 上训练了预测模型,并在NS队列上进行了测试.
- 社会响应量表 (SRS) 评分被用于量化ASD症状严重程度.
主要成果:
- 在NS队列中,CPM成功预测了SRS得分 (rs=0.43,p=.011).
- 来自ABIDE队列的预测模型在患有NS的儿童中显著预测了ASD症状 (rs=0.460,p=.018).
- 两个队伍的共享预测性大脑网络涉及皮质下大脑和视觉处理区域.
结论:
- 与ASD症状相关的功能性大脑网络显示趋同,无论遗传诊断如何.
- 在ASD中RAS-MAPK通路的作用是由NS和异形ASD中共享的大脑网络突出显示的.
- 人类遗传模型,如NS,对于推进理解非异常性ASD至关重要.

Autism Spectrum Disorder
981
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.

Attention-Deficit/Hyperactivity Disorder
776
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....
