Hemialexia is defined in the narrow sense as an inability produced by a cerebral lesion in comprehension of written words presented in one of the two visual hemifields (Benson and Geschwind, 1969). However, in some patients diagnosed as hemialexic [e.g., Trescher and Ford’s (1937) case and Maspes’ (1948) cases] it is difficult to identify whether their disturbances are in comprehension (i.e., word-to-picture matching) or in reading aloud. Thus, hemialexia may be classified into two categories: type I hemialexia, an inability to comprehend written words, and type II hemialexia, an inability to read aloud written words or letters.
