Memory Impairment after Stroke of Internal Capsule-basal Ganglia / 中国心理卫生杂志

ABSTRACT

Objective:to study memory impairment of patients with stroke in internal capsule-basal ganglia.Method:40 inpatients with stroke in internal capsule-basal ganglia and 25 aged matched normal control received assessment with MMSE (mini mental state examination), WMS-RC (Wechsler memory scale-Chinese revised), AVMT (auditory verbal memory test) and MPS (memory for pictorial scenes test). The patients were assessed in 20 days after stroke while the loci were determined by cranial CT or MRI.Result:among patients, the total scores of these memory tests were associated with cerebral atrophy, educational level, and leukoaraiosis. The volume of lesion and leukoaraiosis played a major role in memory coding strategy in MPS test. There were still significant differences in above memory tests between patients without cerebral atrophy and the matched controls.Conclusion:damage of sub-cortical rgions, such as lesions of internal capsule-basal ganglia, may cause memory impairment.
