Abstract：This paper introduces the clinical experience of Professor ZHAO Jingwei in treating vascular dementia from spleen and stomach. Professor ZHAO Jingwei believes that the deficiency of the spleen and stomach leads to insufficient transportation and transformation，the disturbance of qi movement in spleen and stomach leads to the damage of five viscera， and the insufficiency of spleen and stomach leads to endogenous phlegm stasis，which can cloud the seven orifices. The dysfunction of the spleen and stomach is the key to the disease of vascular dementia. Clinically， it can be divided into five syndrome types： spleen- stomach deficiency and failure syndrome， heart- spleen deficiency syndrome， spleen- kidney deficiency syndrome， phlegm clouding the seven orifices syndrome， and phlegm- stasis mutual obstruction syndrome. Xiangsha Liujunzi，Siwu Decoction，and Buzhong Yiqi Decoction，etc. are used for spleen- stomach deficiency and failure syndrome；Guipi Decoction and Renshen Yangrong Decoction are used for heart- spleen deficiency syndrome； Huanshao Pills is used for spleen- kidney deficiency syndrome； Ditan Decoction and Zhimi Decoction are used for phlegm clouding the seven orifices syndrome； the combination of Kaixin Powder， Zhimi Tang， Diandao Mujin Powder and Siwu Decoction can be modified for phlegm- stasis mutual obstruction syndrome. Make prescriptions based on different syndromes，so that a good effect can be obtained.
