These problems can cause the discordant account of phonological dyslexia and dysgraphia where people reveal serious punctuation disabilities although their word reading capability is typical. These findings support the sight that the honesty of phonological depictions plays an important duty in the success of composed language processing and that lesion location within the perisylvian language area dependably creates a dissociation between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion processes required for non-word analysis and punctuation (Coltheart, 2006).

Speech language pathologists can assist children with phonological dyslexia improve their abilities by working with sounding out strange words and constructing their tank of recognized view words.
