The treatment group received low-dose ACTH and prednisone、topiramate、vitamine B6 、gamma globulin. The two groups all completed a therapeutic period of 3 months. Results The effect of the treatment group compared with the control group has significantly statistical difference (P ＜ 0.05) ;the result of the treatment group'electroencephalogran compared with that of the control group also has significants difference (P ＜ 0.05). Conclusion The therapeutic effect of low-dose ACTH and prednisone、 topiramate、 vitamine B6、 gamma globulin together on infantile spasms was much better than just taking sodium valproate only.
