ABSTRACT
Objective To investigate the relationship between cognitive impairment and the other clinical features of subcortical damage in patients with magnetic resonance imaging(MRI)-defined subcortical ischemic vascular disease(SIVD).Methods The cohort for this study included 110 SIVD patients who were divided into 3 groups according to cognitive status:patients with noncognition impairment(SIVD-NCI group,n=34),patients with mild cognitive impairment(SIVD-MCI group,n =47) and patients with vascular dementia (SIVD-VaD group,n =29).The cognitive functions were evaluated by the mini-mental state examination (MMSE) and Montreal cognitive assessment(MoCA),the Cambridge cognitive examination-Chinese version(CAMCOG-C),activity of daily living scale(ADL) and clock drawing task(CDT),etc.Depression symptoms were assessed by the geriatric depression scale (GDS),while the other clinical features of subcortical damage were assessed by the timedGet-Up and Go test,etc.Results There were statistically significant differences in the MMSE,MoCA,CAMCOG-C,CDT and ADL scores among the three groups(H=85.36,F=50.32,55.03,H=27.39,40.87,respectively,all P<0.05).Gait disturbance,urinary disorder,pseudobulbar palsy,depression and falls were statistically significantly different among the threegroups(x2=21.69,21.41,25.51,6.91,21.87,all P<0.05).In addition,gait disturbance was increasingly aggravated with the severity of cognitive impairment.In SIVD-MCI group,urinary disorder,pseudobulbar palsy and falls were significantly increased as compared with SIVD-NCI group (x2 =15.57,16.31,8.92,both P<0.017).Depression was statistically significant different between SIVD-NCIandSIVD-VaD group(x2 =6.90,P<0.017).Among the three groups,there was no significant difference in the feature of emotional incontinence.Conclusions With the decline in cognitive function,the patients with SIVD can present with different clinical features of subcortical damage.Gait disturbance is gradually aggravated with the decline in cognitive function.Urinary disorder,pseudobulbar palsy,and falls can reflect the cognitive impairment from normal to mild on the other hand.Depression can be used as one of the signs that show cognitive impairment reached to dementia.
