老年性痴呆与血管性痴呆智能障碍的比较研究

INTELLECTUAL IMPAIRMENT COMPARISON BETWEEN THE SENILE DEMENTIA AND VASCULAR DEMENTIA PATIENTS

目的方法研究比较老年性痴呆和血管性痴呆智能障碍的异同。方法应用长谷川氏痴呆评定量表检查法、简易精神状态检查法(MMSE)、Kohs立方体组合测验(Kohs测验)检查法,对老年性痴呆和血管性痴呆患者进行测查,并与正常老人加以对照比较研究。结果血管性痴呆组的长谷川氏、MMSE测验分数都显著高于老年性痴呆组。对长谷川氏量表六个方面进行比较发现:血管性痴呆组与老年性痴呆组在近记忆方面差异不明显,在远记忆方面有显著差异。血管性痴呆者的病程分别与MMSE测验值和长谷川氏量表测验值进行相关分析,结果显示,病程与两者呈负相关关系(r分别为:-0.25、-0.23,P<0.05)。说明血管性痴呆者的记忆能力随病程的增加而下降。老年性痴呆组的病程与长谷川氏量表中识记能力得分呈负相关(r=-0.36,P<0.05)。说明老年性痴呆者的识记能力随病程的增加而下降。结论血管性痴呆者早期仅表现近记忆障碍,远记忆相对保持较好,随病程的增加,远记忆能力逐渐丧失,智能衰退呈渐进性加重。而老年性痴呆早期就表现出远近记忆障碍,智能衰退呈现出一种缓慢的进展过程。

Objective To study Intellectual impairment comparison between the senile dementia and vascular dementia patients. Methods In this paper we used the Hasegawa Dementia Scale （HDS） , MMSE and Kohs Block -design Test （KohsTest） to exam senile dementia patients and dementia caused by cerebrovascular disease , healthy elder people were included in control groups . Results The scores of the three tests in the dementia group were significantly lower than that in the non - dementia group. In the dementia group, the scores of the three tests were statistically indifferent between the senile dementia and the vascular dementia. The course of vascular dementia was connected with the scores of HDS and MMSE（r = -0.25, -0.23 ,P 〈 0.05） , The course of senile dementia was connected with the scores of Rote Learning Ability （ r = - 0.36, P 〈 0.05 ）. Conclusion Memory impairment are different between the senile dementia and vascular dementia patients.
