These troubles can bring about the discordant account of phonological dyslexia and dysgraphia where people reveal extreme punctuation problems despite the fact that their word reading ability is normal. These findings support the view that the stability of phonological depictions plays a critical role in the success of written language processing and that sore area within the perisylvian language area dependably creates a dissociation between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion procedures required for non-word analysis and spelling (Coltheart, 2006).

Speech language pathologists can assist kids with phonological dyslexia enhance their skills by dealing with sounding out unfamiliar words and building their reservoir of recognized sight words.
