Abstract:
BACKGROUND: Handedness is always used for judging language dominant hemisphere. Chinese character is a sort of ideographic writing which is different from phonetic writing and the language-dominant hemisphere may also be different.OBJECTIVE: To analyze the relationship of handedness with languagedominant hemisphere of patients with cerebral infarction whose native language is Chinese.DESIGN: Case observation.SETTING: Department of Neurology, Hongqi Hospital Affiliated to Mudanjiang Medical College.PARTICIPANTS: A total of 400 cases of patients with cerebral infarction verified by CT and MRI were admitted in Department of Neurology of affiliated Hongqi Hospital of Mu Danjiang Medical College from February 2003 to June 2004. There were 249 male cases and 151 female cases of average age of (67.45±5.67) years old, with a course of disease of 2-4 weeks.METHODS: Handedness criterion made by Department of Neurology of First Affiliated Hospital of Beijing Medical University was used to judge handedness, and western aphasia battery was applied for classification of aphasia types.MAIN OUTCOME MEASURES: Relationship of handedness with language-dominant hemisphere of patients with cerebral infarction.RESULTS: According to actual procession and analysis, all the 400 cases entered results analysis. ① There were 366 cases of right-handedness and 34 cases of non-right-handedness. ② There were 169 cases of patients with aphasia out of 237 cases of left hemisphere lesions and 9 cases of patients with aphasia out of 163 cases of right hemisphere lesions. ③ Among 366 cases of right-handedness, there were 158 cases of aphasia out of 218 cases of left hemisphere lesions and 7 cases of aphasia out of 148 cases of right hemisphere lesions. Among 34 cases of non-right-handedness, there were 11 cases of aphasia out of 19 cases of left hemisphere lesions and 2 cases of aphasia out of 15 cases of right hemisphere lesions. CONCLUSION: Among people whose native language is Chinese, most dominant hemispheres of right-handed people among patients with cerebral infarction are left cerebral hemispheres and few are right cerebral hemispheres; most dominant hemispheres of non-right-handed people are left cerebral hemisphere and few are right cerebral hemisphere.
