儿童多动综合征又名儿童轻微脑功能障碍(Minimal brain dysfnncfion Syndrome 简称MBD),其病因不明。脑损伤、中枢神经系统成熟延迟、遗传因素、环境因素均被认为与本病有关。近20余年来,从生物化学的角度观察 MBD 的病因及发病机制受到很大重视。因此,对 MBD 的生化代谢作进一步探讨,有助于阐明本病的病因和病理机制,对临床诊断和 Children’s hyperactive syndrome, also known as Minimal brain dysfunction syndrome (Minimal brain dysfnncfion Syndrome referred to as MBD), the etiology is unknown. Brain damage, delayed central nervous system development, genetic factors, environmental factors are considered associated with the disease. In the recent 20 years, the etiology and pathogenesis of MBD have been given great attention from the perspective of biochemistry. Therefore, to further explore the biochemical metabolism of MBD, help to elucidate the etiology and pathology of the disease, clinical diagnosis and
