Brief summary
The purpose of this study is to explore the pathogenesis of cognitive impairment after acute cerebral infarction by applying the multimodal function MRI to dynamically observe the changes of the value of NAA,Cho,Cr,FA in a certain region in the brain and the function of the brain ,and to provide a visual instrument for evaluating the therapeutical effects of Chinese medicine through the application of multimodal function MRI to observe the changes of the neurotransmitter in certain area in the brain before and after the treatment.
Detailed description
The present study is designed to assess the efficacy and safety of Jianpi Yishen Huatan granules with cognitive impairment after Acute Cerebral Infarction by fMRI and neuropsychology scales,as well as observe the symptoms,syndrome characteristics and neuropsychological changes of patients with cognitive dysfunction after acute cerebral infarction.And explore the pathogenesis of cognitive impairment after acute cerebral infarction by applying the multimodal function MRI to dynamically observe the changes of the value of NAA,Cho,Cr,FA in a certain region in the brain and the function of the brain ,and to provide a visual instrument for evaluating the therapeutical effects of Chinese medicine through the application of multimodal function MRI to observe the changes of the neurotransmitter in certain area in the brain before and after the treatment. The sample size is 40 of which 20 are from the intervention group and 20 are from the control group.
