Pure alexia

Main article: Alexia (acquired dyslexia)

Pure alexia, also known as agnosic alexia or alexia without agraphia or pure word blindness, is one form of alexia which makes up "the peripheral dyslexia" group.[1] Individuals who have pure alexia have severe reading problems while other language-related skills such as naming, oral repetition, auditory comprehension or writing are typically intact.[2]

Pure alexia is also known as: "alexia without agraphia",[1] "letter-by-letter dyslexia",[3] "spelling dyslexia",[4] or "word-form dyslexia".[5] Another name for it is "Dejerine syndrome", after Joseph Jules Dejerine, who described it in 1892;[6] however, when using this name, it should not be confused with medial medullary syndrome which shares the same eponym.
