中文摘要: 注意缺陷多动障碍(ADHD)的客观诊断是当今儿童精神卫生领域的热点研究课题。静息状态功能磁共振成像(fMRI)技术在神经精神疾病的分析与辅助诊断方面具有独到优势,基于该技术的神经精神疾病研究的广泛开展使得融合多中心静息状态fMRI数据形成大样本进而开展神经精神疾病分类研究成为未来脑功能研究的一个重要发展方向。本项目将基于多中心大样本静息状态fMRI数据进行ADHD分类研究。具体地,本项目将在解决目前多中心大样本静息状态fMRI数据分析中存在的共性问题(如被试头动因素、多数据采集中心因素、样本年龄跨度因素等的影响)的基础上,采用独立成分分析、复杂脑网络分析等fMRI数据分析方法提取分类特征,并结合适当的分类算法,开展ADHD分类研究。本项目在促进ADHD的客观诊断之外,还将为未来基于多中心大样本静息状态fMRI数据的其它神经精神疾病的分类研究提供借鉴。

英文摘要: The objective diagnosis of Attention Deficit / Hyperactivity Disorder (ADHD) is one of the research foci in the region of children mental health. Resting state fMRI is an advantagous technique for the pathology analyses and computer-aided diagnoses of psychiatric diseases. The extensive investigations of psychiatric diseases based on resting state fMRI make it a promissing research region to integrate resting state fMRI data from different research centers into one dataset and perform psychiatric disease classification based on this integrated multi-center & large-sample-size dataset. This project is aimed at ADHD classification based on multi-center & large-sample-size resting state fMRI dataset. This project will be performed by: (1) solving the common problems in the analysis of multi-center large-sample-size fMRI data (such as the influences of head motion, age range and different data collection sites); (2) using novel fMRI data analysis methods (such as independent component analysis and complex brain network analysis) in combination with proper classification algorithms. The project would not only facilitate the objective diagnosis of ADHD, but also benefit the classification of other psychiatric diseases based on multi-center & large-sample-size resting state fMRI datasets.
