A study on intelligence of patients with cerebral infarction

Objective To research the characteristics or intelligence damage and the influence of different infarcted parts on intelli.gence in cerebral infarction patients. Methods The intelligence test and analysis was performed in 48 cases of cerebralinfarction add 43 normal subjects by WAIS-RC. The dysnoisia degree of patients were compared with that of normal subjects, the relationship between dysnoisia and region of infarction was analyzed. Results For every tested items, the scores of cerebral infarction group are significantly lower than that of control group (P 0.01),the dysnoisia scores of left part infarcted cases are lower than that of right part infarcted, the cerebral cortex infarction are significantly lower than cerebral subcortex (P 0.01). Conclusion Cerebral infarction can cause obvious intellectual dysfunction.The influences of left side infarction on intelligence is more serious than thatof right side, especially for that of language expression and abstract thought. The damage of intelligence of cerebral cortex infarction is more serious than that of cerebral subcortex infarction.
