The effect of treatment is negatively correlated with the course of disease, generally, the effect is much worse with the course of disease is much longer; The effect is positively correlated with the course of treatment, it is better if the course of treatment is longer.The group of more than one year is much excellent than the group of less one year. The ex-electroencephalogram before treatment is normal, on edge and a little abnormal, the effect is better. As regards CT or MR result, there is difference between the effective group and the ineffective group. The result of CT and MR is negative, the effect is better, and the effect to demyelination and leukoencephalopathy is most worst.However,for the tipe of much abnormality, the effect is the most worst.The effect is related to course of disease.The effect is better if the course is shorter.There is no difference in the tipe of disease the symptoms before episode, the frequency of episode, the inducing reasons, the age, sex and so on.

病程的长短与疗效存在负相关关系，病程越长疗效越差；疗程与疗效存在正相关关系，疗程越长疗效越好；疗前脑电图的异常程度与疗效存在负相关关系，正常、边缘及轻度异常者，疗效较好，重度异常者疗效最差；无效组与有效组在CT及MR检查结果上有差异，有阴性者疗效好，阳性者疗效差，脱髓鞘及脑白质病疗效最差的趋势；疗效与性别无相关性；无效组与有效组在发作类型、既往病史、辨证分型、发作先兆、疗前发作频率、诱因、发病年龄、就诊前所用药物方面无差异。

As a whole, this article investigates the investment effect problem from a new view of regional economics. It covers the economic, social and ecological effect of regional investment; it defines the concepts of investment effect and regional investment effect, deciphers the connotation, classification and influential factors of investment effect, and establishes a basic theory framework of investment effect research; constructs a fire-new regional investment effect evaluation model that could evaluate comprehensively the economic, social and ecological effect of regional investment, including evaluation index system and evaluation method, which supplies the gap of regional investment effect evaluation in academic community.
