ObjectiveTo observe the difference of the memory disorder between the right and left basal ganglia lesionsMethods50 cases in each group were observed,with single lesion in the left basal ganglia area (A group) and in the right basal ganglia area (B group)The memory functions of patients were tested with revised Wechsler Adult memory scale,the scores were recorded,memory quotients were calculated and statistical analyzed to determine the type of memory dysfunctionResultsThe disorders of memory in A group were mainly verbal memory and short\|term memory disorder,in B group were mainly in non\|language memory and graphic,visual spatial memory disordersConclusionThe memory function changed significantly in patients with left basal ganglia area lesion,mainly affecting the memory function associated with the language,suggesting that the left basal ganglia area has the laterality advantage in memoryIn the group with right basal ganglia lesion,graphic,visual\|spatial memory deficits damaged more obviously,indicating that the right basal ganglia area,like the right hemisphere,has dominant in visuospatial functionKey Words:Basal ganglia；Cerebrovascular lesions；Memory disorder；Trait analysis
