| Aim To reveal the correlation factors of cognitive disorder after thalamic stroken.Methods and Objects There are 23 cases of thalamic stroke diagnosed on the basis of 1.5 tesla MRI. All patients are from department of neurology in the ZhongShan subsidiary Hospital of DaLian University and the Liberation Army 210 Hospital. In the same time, 46 cases health control are collected from community. All patients have been tested by Wechsler Adult Intelligence Scale (WAIS), Wechsler Memory Scale (WMS), Wisconsine Card Sorting Test (WCST), Trail Making Test A and Trail Making Test B. We have used t test, chi-square, two independent samples, spearmen correlation.Result There are no significant different in the sex, age and education degree between the two groups. 1) Group of thalamic stroken compare with health control for recognition index, there are significant different between the two groups at vocabulary, Executive complete number of categories, Executive erron responsive number, non Executive persist error number (nRpe), the trail making test A, the trail making test B, Visual recognition, Figure recall, Visual recall, Association thinking, the touch recognition and memory, and Inverse recite (P<0.05). 2) Comparation of cognition after different parts of thalamic stroke: Only three items of cognition have significant difference(P<0.05), those are Association thinking, touch recognition and memory and comprehensive memory. 3) Correlative analysis: Executive erron responsive number and non Executive persist error number have positive correlation with stroken volume (rs >0, P<0.05), but visual recognition and Inverse recite have negative correlation withstroken volume (rs <0, P<0.05).Conclusions Thalamic stroken can cause various cognition disorders, especially in vocabulary intelligence, executive function and working memory. The left and right thalamic stroken may have different effect on short-term memory. Stroken volume influence cognition. |
