The characteristics of mild cognitive impairment and Electroencephalography in acute ischemic stroke

Objective To investigate the characteristics of mild cognitive impairment and Electroencephalography(EEG) in acute ischemic stroke. Methods 19 amnestic type-MCI(MCI-A)and 13 vascular type-CI(MCI-V)were determined and classified according to the diagnostic criteria.The neurobehavioral cognitive status exam assessment was used to assess cognitive function.The Fugl-Meyer motor assessments were used to assess motor function.Comparing the results on EEG characteristics between MCI-A and MCI-V.The controlled group came from normal old individuals.Results Comparing the normal group,the attention,construction,memory and calculation were impaired in the MCI-A group.All parameters in MCI-V group were lower than normal value.The Fugl-Meyer indexes of MCI-V is lower than MCI-A(P0.05).There are 9 MCI-V patients and 4 MCI-A patients had moderate abnormal EEG and 3 MCI-V patients and 15 MCI-A patients had mild abnormal EEG.Conclusions The cognitive impairment is severe in MCI-V than in MCI-A.EEG can be imaged as the index in this difference.
