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. 这项研究使用预测建模来将NS大脑连接与ASD症状联系起来,在数据集中验证发现.

科学领域:

神经科学是一个神经科学.
遗传学遗传学是一个
发育儿科发育儿科

背景情况:

自闭症谱系障碍 (ASD) 病理生理学并未得到充分理解,尽管其流行程度很高.
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的儿童是研究ASD遗传和神经学的基础的宝贵模型.

研究的目的:

研究与NS儿童社会障碍相关的功能性大脑网络解剖学.
测试ASD症状预测模型的概括性,在一个大型的非综合征队列 (ABIDE) 中开发到患有NS的儿童.

主要方法:

使用了功能磁共振成像 (fMRI) 和基于连接体的预测建模 (CPM).
应用CPM对患有NS的儿童的fMRI数据 (n=28) 来预测自闭症症状严重程度 (SRS得分).
来自ABIDE队列 (n=352) 的预测模型被测试了其预测NS队列症状严重程度的能力.

主要成果:

预测模型与NS儿童观察到的社会响应得分有显著的相关性 (r=0.43,p=0.011).
在自闭症丰富的ABIDE队列中开发的模型也显著预测了NS队列中的症状严重程度 (r=0.46,p=0.018).
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:

尽管NS队列很小,但交叉数据集验证取得了成功,突出了对罕见遗传综合征的大型公共数据集的有用性.
融合的功能连接模式表明,在NS和非综合征性ASD中,自闭症症状的神经学基础是共同的.
对RAS-MAPK通路失调的进一步研究是有必要的,以了解其在ASD相关的大脑功能中的作用.

Autism Spectrum Disorder

Autism Spectrum Disorder

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.

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Social Anxiety Disorder

Social Anxiety Disorder

Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.
