title: Lesion localization of phonological agraphia.
abstract: Phonological agraphia is a neurolinguistically specific profile of spelling impairment. It is characterized by an impairment in spelling pronounceable pseudowords ('sild') and by an impairment in spelling real words related to their familiarity, length, and often, part of speech (Shallice, 1981; Roeltgen, 1985; Bub & Chertkow, 1988). We report two cases of phonological agraphia, each with a different lesion profile. Analysis of the small number of published cases that include lesion data, plus our own cases, suggests that phonological agraphia can be produced by lesions in a wide range of perisylvian cortical regions that have in common some role in central phonological processes.
