Abstract:
Objective To study the characteristics of working memory impairment in patients with lacunar cerebral infarctions(LCI).Methods 42 patients proved by clinics were chosen,and divided into two groups:multiple and single LCI groups,versus left,right and double side infarction groups.Their working memory status were evaluated and compared with Digit Ordering Test,Corsi block task,House Visual Span Test and Stroop Digit Counting Test.All scores were analyzed statistically.Results(1)All scores of the four types of Tests in multiple LCI group were significantly lower than those in single group(P0.05).Conclusions Multiple LCI is closely related to working memory impairment.Left brain infarction may induce verbal working memory impairment,and right infarction may induce spatial working memory impairment,but object working memory impairment may related to double side of brain infarction.It suggested that in the physiological structure,different components of working memory regions had dissymmetrical effect in two sides of brain.
