摘    要:借鉴流体力学中用子波变换识别湍流相干结构的能量最大准则,解释婴儿痉挛症发病的三联征,尤其想说明智能迟滞的原因.从电生理的角度来说明,为什么脑干是婴儿痉挛症的责任病灶——这个生化及病理已经做出的推测.研究发现婴儿痉挛症患儿的脑干通道对外界刺激的反应能力和信息的传递能力与正常儿童有明显差异,借用能量最大准则在湍流中的解释,认为是因为信息传导阻滞引起患儿智能发育的迟滞,并试着提出评价最理想治疗效果的标准.

关 键 词:婴儿痉挛症,脑干诱发电位,子波变换,能量最大准则

Abstract:In order to explain the reason why brainstem is responsible for the mental retardation in infantile spasms, the maximum energy criterion for burst-event identification in wall turbulence by wavelet analysis was used. It is found that the brainstem-channel of IS patients is very different from that of normal ones in response to stimulation and information transfer. According to the explanation of maximum energy criterion in the turbulence, it was noticed that mental retardation in IS is caused by the block of information transfer in the brainstem. Furthermore, the importance of this method for treatment evaluation is also indicated.
Keywords:infantile spasms   brainstem auditory evoked potential  wavelet transforms   maximum energy criterion
