Evaluation Of Brain Dysfunction And Outcome In Cerebral Infarction With Somatosensory Evoked Potentials

[Objective]The aim of this study was to discuss the value of somatosensory evoked potentials(SEPs) in judging brain dysfunction and its prognosis in the patients with cerebralinfarction ,as well as to explore the correlation between SEP changes and variousgroups of cerebral infarction.[Methods]159 patients were submitted to SEPs recording within 7 days after attack of cerebralinfarction confirmed by CT or MRI,and consequently divided into three groups based onSEPs abnormality:normal,slight-moderate and severe.These patients were assessed usingNIHSS at onset and at post-stroke 1 month respectively.[Results]The results indicated that SEPs were frequently altered in patients with stroke inparietal lobe and thalamus. NIHSS score was statistically significant among three groupswith different levels of SEPs abnormality both at onset and in 1 month(P<0.01).And theSEPs abnormality was in direct proportion to the NIHSS score,as well as to the severityof brain dysfunction.[Conclusions]The SEPs changes were correlate to different lesion.Application of SEPs recordinghas significant value for predicting the extent of brain dysfunction and its prognosis incerebral infarction.
