Mirror writing in the elderly.
OBJECTIVE
To determine if examination of mirror writing in the elderly could be used to assess the degradation of the brain function.


METHODS
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 +/- 13.4. These subjects were divided into two groups, a non-elderly group consisting of 60 subjects (41.1%) and an elderly group 86 subjects (58.9%). All 146 subjects were examined with 10 items for determination of handedness, mini-mental state examination and the written language of Chinese Aphasia 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.


RESULTS
The results of examination revealed that in 146 subjects there were 7 subjects with mirror writing, which occurred only in the elderly group, accounting for 8.1%. In the elderly 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.


CONCLUSIONS
It is suggested that examination of mirror writing in the elderly may be used to assess the degradation of the brain function in senile subjects.
