Abstract:
Objective To investigate the characteristics of brain imaging and its relationship with the cognitive disorders in vascular dementia patients. Methods The volumes of cerebral lobes and hippocampus formation in 30 ischemic vascular dementia patients and 30 normal controls were measured with MRI based technique. The indices of ventricles and cerebral sulci in 30 ischemic vascular dementia patients and 30 patients with ischemic stroke were calculated with CT based technique. The cognitive functions were assessed by psychometric testing (Mini Mental State Examination MMSE, Brief Screening Scale for Dementia BSSD, Raven's Standard Progress Matric RSPM) in all subjects. Results The volumes of frontal and temporal lobes in vascular dementia patients were smaller than those in ischemic stroke patients and normal control subjects ( P 0.05). The decrease of the volumes of the frontal and temporal lobes were positively correlated with the decrease of MMSE and BSSD scores. The cognitive disorders were more severe in the ischemic vascular dementia patients with pathological foci in the frontal and temporal lobes, multiple infarcts, and the total volume of infarcts greater than 50 mm 3 ( P
