mirror writing
Production of reversed script that appears normal when viewed in a mirror, often seen in children and certain neurological conditions.
Full Definition
Mirror writing refers to the production of script that is reversed horizontally, appearing as a mirror image of normal writing. While common in young children learning to write, pathological mirror writing can occur following brain injury, particularly involving the right hemisphere or corpus callosum. The phenomenon may represent disinhibition of normally suppressed mirror programs in the non-dominant hemisphere for writing. Leonardo da Vinci famously used mirror writing extensively, though whether this was intentional or pathological remains debated. In clinical contexts, mirror writing may indicate hemispheric disconnection, parietal lobe dysfunction, or developmental writing disorders requiring careful assessment.
