A Clinical Study on Neglect Syndrome in Unilateral Hemispheric Lesion

ABSTRACT

We investigated 97 right-handed comprehensive patients with unilateral hemispheric lesion confirmed by computed tomogram, to evaluate the presence of neglect syndrome by using tests of visual neglect, auditory extinction, and somesthetic extinction. The results are as follows 1.Neglect syndrome was noted in 38.8% of right hemispheric lesion and 25.6% of left hemispheric lesion, the frequency of neglect syndrome was higher in new lesion(less than 1 month) than old(over than 1 month) and the common locations of neglect syndrome were parieto-occipital, temporo-parietal, fronto-temporo-parietal, and parietal in that order. 2. The severity of neglect syndrome showed higher correlations with right hemispheric lesion and new lesion, but without any significant correlation with the location of lesion.
