脑损害患者三维空间结构障碍研究

Study of Three-dimensional Constructional Defect in Patients with Cerebral Damage

目的：了解脑损伤患者三维空间结构障碍发生率，三维空间结构障碍与脑损害定位、定侧关系。方法：用积木三维空间构图法对６０例对照者，８６例脑损害患者三维空间结构进行检测。结果：脑损伤患者三维空间结构障碍发生率明显高于对照者；三维空间结构障碍检出率明显高于二维空间结构障碍检出率；右半球损害三维空间结构障碍发生率较左半球损害者高，且更严重；顶叶及丘脑受损者三维空间结构障碍发生率最高。结论：大脑半球各部位损伤均可导致三维空间结构障碍，但以右半球顶叶及丘脑受损最严重，发生率最高。

Objective:To evaluate the incidence of three-dimensional constructional defect in patientswith cerebral damage and its relation to the location and laterality of the cerebral damage. Method: Eighty-six patients with cerebral damage and 60 healthy controls were evaulated by a three-dimensional block construction task. Results: The incidence of three-dimensional constructional defect in patients with cerebral lesion was significantly higher than that of the healthy controls; The incidence of three-dimensional constructional defect was significantly higher than that of two-dimensional constructional defect in brain-damaged patients; Both left hemisphere lesion and right hemisphere lesion can result in three-dimensional constructional defects, however, the impairment was more severe for patients with right hemisphere lesions, especially when the lesions were located in the right parietal lobe or thalamus.Conclusion: Hemisphere lesions may lead three-dimensional constructional defect, however, the severity of the impairment is associated with right parietal-lobe or thalamus lesions.
