Mirror-writing is the process of reversing individual letter and composing word sequence in opposite direction. Unintentional mirror writing has been observed in young children learning to write and interpreted as the manifestation of different cognitive impairments. It is very rare that normal right-handed adult shows mirror writing. However, the acquired "mirror writing" may be shown in left hemispheric stroke, neurodegenerative disease, and diffuse cerebral disorders. To explain this event, some assumption have been indicated such as the motor, the visual dominance, the supplementary motor area, the visio-spatial, the visual word-form, the hemispatial factor or directional and the reflected graphemic 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 reported a case of "mirror-writing" with left thalamic hemorrhagic stroke.
