Abstract
Objective To investigate the value of P300 in vascular mild cognitive impairment(vascular mild cognitive impairment,VaMCI) in.Methods Patients with acute cerebral infarction group selected performance without dementia who were 40,60 hypertension patients and 40 healthy volunteers selected human normal control group,three groups of subjects MoCA score measured value,P300 peak potential latency volatility,N200-P300 wave interval.Results Compared with normal control group,patients with cerebral infarction and hypertension patients MOCA score lower,P300 latency,N200-P300 wave interval,CI group to change more obvious,the differences were statistically significant;P300 volatility than normal control groups,but statistically significant cerebral infarction group,hypertension group was not statistically significant.Compared with patients with hypertension,cerebral infarction group MOCA score lower,P300 latency,amplitude extended,N200-P300 wave interval prolongation,the difference was statistically significant.Conclusion Patients with hypertension but no occurrence of stroke,dementia-free performance there is no damage cognitive function in patients with acute cerebral infarction,measuring P300 facilitates early diagnosis of vascular cognitive dysfunction;provide an important basis for the intervention forward.关键词
