老年人镜像书写研究

Study on mirror writing in the elderly

１９９３年１～１０月我们检查了健康受试者１４６名的镜像书写情况，男性１０４名、女性４２名，年龄为４０～８５岁。其中老年组８６名，占５８．９％；非老年组６０名，占４１．１％。为避免教育程度低的影响，皆选大学毕业生，进行了１０项利手测定，简易精神状态量表（ｍｉｎｉｍｅｎｔａｌｓｔａｔｅｅｘａｍ，ＭＭＳＥ）测定，并采用《汉语失语症检查法（草案）》中书写部分进行检查，方法为用右手和左手分别进行自发书写、抄写和听写。１４６名中检出镜像书写者７名，均为老年人，占老年组的８．１％，７０～７９岁组１名，８０～８５岁组６名。就镜像书写、受教育程度和年龄进行了讨论，并建议镜像书写的检查可以作为老年人智力测定的项目之一。

Abstract The occurrence of mirror writing in 146 subjects was examined.Among them, 104 were males and 42 females. All subjects were university graduates. Age ranged from 40 to 85 years with an average of 62.7±l3.4. These subjects were divided into two groups, a non-senile group consisting of 60 subjects (41.1%)and a senile group 86 subjects (58-9%). All 146 subjects were examined with 10 items for determination of handedness, mini mental state exam and the written language of Chinese Aphasic Examination Scale (draft)including spontaneous writing, writing from dictation and copying. The above mentioned performances of written language were done by left and right hand. The results of examination revealed that in 146 subjects there were 7 subjects with mirror writing, which occurred only in the senile group, accounting for 8.1%. In the senile group mirror writing was found in one subject of 70-79 years group and 6 subjects of age over 80 years. Mirror writing appeared in the elderly was of mild degree with an average Percentage of 1.9±0.4.The relationship between mirror wrinting, education level and aging was discussed.
