Autism Spectrum Disorder01:19

Autism Spectrum Disorder

90
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.

  • 将全脑和关键的ASD相关脑子网络功能连接数据纳入GCN模型.
  • 为了解决自闭症脑成像数据交换 (ABIDE) 数据集中的异质性,使用一种新的外部注意网络读取 (EANReadout).

主要方法:

  • 开发MFC-GCN框架,整合全脑和子网络功能连接.
  • 引入EANReadout机制来处理数据集异质性和探索主题关联.
  • 在ABIDE数据集上进行实验验证,包括714名受试者.

主要成果:

  • 拟议的MFC-GCN框架在ABIDE数据集上实现了70.31%的平均准确性.
  • 新的EANReadout显著超过了传统的读取层.
  • 通过EANReadout,整体框架准确度提高了4.32%.

结论:

  • 与EANReadout一起的MFC-GCN框架通过利用多层次的大脑连接信息,为早期ASD诊断提供了更有效的方法.
  • EANReadout对于管理数据异质性和提高ASD研究中的分类性能至关重要.
  • 这项研究强调了先进的GCN技术在基于神经成像的疾病诊断方面的潜力.
