Abstract
The Wechsler-Bellvue Adult Intelligence Scale was performed to thirty-four hemiplegic patients who were diagnosed as cerebrovascular lesion of internal capsule and ten healthy persons as control. Distributions of age, sex and grade of education of both groups were not statistically significant. The results were as follows:
1) The scores of hemiplegic group was lower than that of control group, especially the difference was statistically significant in total verbal scale, total performance scale, information, arithmetic, similarities, digit span and picture arrangement.
2) Mean score of total verbal scale of right hemiplegics was lower than that of left hemiplegics, but the difference was not statistically significant except that of arithmetic and digit span.
3) Comparing the differences between verbal and performance scale score of performance scale was lower than that of verbal scale and the difference was statistically significant in left hemiplegic and control group, but in right hemiplegic group the difference of them was not significant because of reduction of the score of verbal scale.
4) No definite relationship was proved between each scores and the presence of conscious disturbance or the time examined.
