Pure alexia is also known as: “alexia without agraphia”, “letter-by-letter dyslexia”, “spelling dyslexia”, or “word-form dyslexia”. Pure alexia results from cerebral lesions in circumscribed brain regions and therefore belongs to the group of acquired reading disorders, alexia, as opposed to developmental dyslexia found in children who have difficulties in learning to read. The patient can still write because the pathways connecting the left-sided language areas to the motor areas are intact. However, many people with pure alexia are able to identify and name individual letters over time as well as recognize sequences of letters as words.
