Abstract

|
|
Mirror-writing is the process of reversing individual letter and composing word sequence in oppositedirection. Unintentional mirror writing has been observed in young children learning to write andinterpreted as the manifestation of different cognitive impairments. It is very rare that normal right-handedadult shows mirror writing. However, the acquired “mirror writing” may be shown in left hemisphericstroke, neurodegenerative disease, and diffuse cerebral disorders. To explain this event, someassumption have been indicated such as the motor, the visual dominance, the supplementary motorarea, the visio-spatial, the visual word-form, the hemispatial factor or directional and the reflectedgraphemic representation hypotheses. It is reported that the lesions which causes the “Mirror-writing”are the parietal lobe, basal ganglia, thalamus and right supplementary motor area, etc. We reporteda case of “mirror-writing” with left thalamic hemorrhagic stroke.
