Abstract

Mirror writing is the simultaneous process of reversing individual letters and composing word strings in the reverse direction. This phenomenon appears rarely only after brain damage. We present the case of a 65-year-old, right-handed man with mirror writing following a left temporo-parietal lobe infarction. He preferred to write in the mirror direction with his left hand, but he did not show any visual-spatial disturbance and allochria. We think that damage to the dominant writing program of the brain, releases the normally suppressed contralesional writing program and this uninhibited program induces the mirror writing. Key Words: Mirror writing, Left temporo-parietal lobe infarction
