注意缺陷多动障碍(ADHD)在学龄儿童中的发病率为3%~5%。核磁共振成像(MRI)证实ADHD儿童的脑部结构存在异常。弥散张量成像(DTI)、脑容积和皮质厚度测定、光谱和功能核磁等各种MRI技术在儿童ADHD患者中进行的临床研究结果表明,与该病的行为紊乱最为相关的脑区是额叶、颞叶皮质、纹状体、胼胝体压部、扣带回、尾状核和小脑。
The prevalence of attention deficit hyperactivity disorder (ADHD) in school-age children is 3% to 5%. Magnetic resonance imaging (MRI) confirmed abnormalities in the brain structure of ADHD children. Clinical studies conducted in children with ADHD using various MRI techniques such as diffusion tensor imaging (DTI), brain volume and cortical thickness determination, spectroscopy and functional magnetic resonance (MRI) showed that the most relevant brain regions associated with behavioral disorders were the frontal , Temporal lobe cortex, striatum, corpus callosum, cingulate gyrus, caudate nucleus and cerebellum.
