An fMRI Study of Jianpi Yishen Huatan Granules for Cognitive Impairment After Acute Cerebral Infarction

Not Applicable
Conditions
Cognitive Impairment
Interventions
Drug: Jianpi Yishen Huatan Granules
Other: the placebo
Registration Number
NCT02752867
Lead Sponsor
Dongfang Hospital Beijing University of Chinese Medicine
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.

Primary Outcome Measures
NameTimeMethod
Changes of the fMRI outcome after the treatment90 days

Using the fMRI to measure the changes of neurotransmitter and brain function in the brain before and after the treatment.

Stroop Color- Word Association Test(Stroop test)90 days

This is a test used to find out the memory and executive function of patients.The test contains three small test.

Numerical sequence test(DS-S)90 days

Using Numerical sequence test(DS-S) to examine memory

Digital color connection test (CCT)90 days

Using Digital color connection test (CCT) to examine executive function and attention

Montreal Cognitive Assessment scale(MoCA)90 days

Using this scale to measure cognitive function

Verbal memory test(HVLT)90 days

Using Verbal memory test(HVLT) to examine verbal memory

Mini-mental state examination(MMSE)90 days

MMSE is an acknowledged scale to measure cognition function from the aspects of orientation ability, memory, attention, calculation ability, recall and language,etc.

Clinical Dementia Rating scale(CDR)90 days

Using Clinical Dementia Rating scale(CDR) to measure the severity of dementia

Secondary Outcome Measures
NameTimeMethod
