ABSTRACT
Objective To investigate the activity of attentional and executive cortex and its relationship with cognitive impairment in subcortical ischemic vascular dementia (SIVD).MethodsTwenty patients with SIVD and twenty normal control subjects who were matched by age,sex and education were enrolled.All of them underwent fMRI using SEMENTS 3.0T MR during Stroop task performance. The correlation between cognitive impairment and cortex activation in fMRI was analyzed.Results Cortical activation of bilateral dorsolateral prefrontal cortex,Nentrolateral prefrontal cortex,inferior parietal lobe have closed correlation with total score,visual trabecular spaces and execution,attention,verbalization,delayed memory and orientation score in MoCA test ( r =0.447-0.837,P < 0.05 ).ConclusionsCortex activation in fMRI can reflex the cognitive impairment of SIVD.
