ABSTRACT
Clinical data of 65 patients with acute cerebral infarction (frontal or temporal or both lobes) treated in our hospital during 2015-2016 were retrospectively reviewed.The patients were followed up for 6 months,34 cases were diagnosed as vascular dementia (VD) according to ICD-10 (VD group) and 31 cases were diagnosed as simple cerebral infarction (control group).The abnormal rate of electroencephalograph (EEG) at baseline in VD group was significantly higher than that in control group (x2 =5.44,P =0.02).Compared to control group,the powers of slow wave (θ wave and δ wave) at baseline,third month and sixth month in VD group were significantly increased (Fbet groups =17.39,Finner groups =163.50,Finteraction =38.71;all P =0.00) and (Fbetween groups =5.10,Finner groups =119.04,Finteraction =6.54;P < 0.05).Compared to baseline,the α wave and β wave were significantly decreased at third month and sixth month in VD (Finner groups =116.40,P =0.00) and (Finner groups =55.90,P < 0.05).Compared to control group,the powers of θ wave (except in the frontal lobe at baseline and third month) and δ wave were significantly increased at all time points (P < 0.05).Except the θ wave in occipital lobe,there were significant differences in slow wave at all time points between VD group and control group (P < 0.05).The featured EEG with increased slow wave in many regions of cerebral infarction can be used for early diagnosis of VD in patients with cerebral infarction.
