摘要
目的从神经心理学角度探讨脑卒中对老年人智能状态的影响。方法对 71例 60— 90岁的住院老年人分别用简易智能状态量表 (MMSE)、标记测验 (TokenTest)、Raven测验进行智能状态的整体评定、言语性理解与非言语性思维活动的测定 ,并对智能内涵与血管性因素进行相关性分析。结果脑卒中组中具有痴呆症状比率为 68% ,明显高于非脑卒中组中的比率 ( 15 % )。在脑卒中组中 ,MMSE与Token得分的相关较MMSE与Raven得分的相关更为明显 ;有脑卒中史者较无脑卒中史者在MMSE、To ken和Raven三者得分之间的相关性方面有显著差异 ;在有痴呆症状的脑卒中患者中 ,年龄与Token得分正相关 ,而年龄、文化程度与Raven得分之间的相关性则在非脑卒中组中表现明显。结论脑卒中可以破坏正常的智能架构 ,加快人智能过程的退化 ,语义性障碍比非言语性思维障碍更早出现。
ObjectiveTo study the impact of stroke on elderly's mental status.Methods71 elderly inpatients aged between 60 to 90 who suffered stroke(31 cases) or not(40 cases) were assessed the mental status as a whole, the evaluation of comprehension of linguistic information,and non-verbal reasoning abilities using Mini Mental State Examination(MMSE), Token Test and Raven Test.The relationships between these cognitive aspects and stroke was also analysed.ResultsThere were 68% of elderly suffering dementia symptoms in stroke group which was much higher than Non-stroke group (15%).The correlation between MMSE and Token is more close than the correlation between MMSE and Raven in stroke group. The correlations among MMSE, Token and Raven were significant different between stroke and Non-stroke groups. There is a positive correlation coefficient between age and Token scores in dementing patients; whereas a closer relationship between age, education level and Raven in Non-stroke group was found. This implied the impacts of stroke on the time-course of mental degeneration.Conclusions stroke can interrupt normal mental structure and speed up the process of degeneration of cognitive functions. Semantic dysfunction might manifestation earlier than non-linguistic functions. Token is more sensitive than Raven in detecting dementia symptoms of stroke type.
