Participant gender:
All
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.
