课题组以往研究显示,正常中国人大脑脚的各向异性分数值正常下限值为0.36,大脑脚面积的偏侧性下限值为0.83,这些数值的变化与肢体动能恢复的关系值得探讨。

中国南方医科大学附属小榄医院宋志彬博士所在课题组进行的一项关于“Why do stroke patients with negative motor evoked potential show poor limb motor function recovery?”的研究,重点显示了磁共振诱发电位阴性时脑梗死患者患侧大脑脚各项异性分数值及面积的变化与其肢体功能恢复的关系。

结果显示,磁共振运动诱发电位阴性的脑梗死患者患侧大脑脚各向异性分数值低于临界点0.36的时间为发病后1-3个月,患侧大脑脚面积偏侧性下降低于下限值0.83的时间为病后6个月,患侧大脑脚各向异性分数值<0.36及大脑脚面积偏侧性<0.83提示偏瘫肢体运动功能恢复不良。

作者认为,研究成果揭示了磁共振运动诱发电位阴性脑梗死患者偏瘫肢体运动功能恢复不良的机制。

不要忽视腔隙性脑梗死

腔隙性脑梗死是脑梗死的一种特殊类型,是在高血压、动脉硬化的基础上,大脑深部的小支动脉发生病变,最终形成血栓或微栓塞导致血管闭塞,形成腔隙性软化病灶。其病变范围一般为2~20毫米,其中以2~4毫米者最为多见。首都医科大学与北京大学公共卫生学院研究人员对我国北方有症状的腔隙性脑梗死研究结果表明,我国北方地区腔隙性脑梗死的发病率为78/10万,我国腔隙性脑梗死在全部脑梗死和缺血性梗死中所占的比例分别为2
