Acquired "pure" alexia (alexi = dyslexia) which means total inability to understand written text and sometimes even what individual letters "are called". There is nothing wrong with visual acuity or shape perception. The victim can copy letters down to the smallest detail but lack an understanding of their meaning. There is a disturbance in the ability for visual pattern recognition. The condition occurs in damage to the left hemisphere of the brain where some of the connections in the lower visual pathway between Brodmann areas 18, 19 and area 39 are interrupted along with right-left connecting brain beam filaments. There is no inability to write yourself; Hence the name "pure" dyslexia.
