Abstract
A right-handed male sustained traumatic brain injury which resulted in anomia, dyslexia, and agraphia. The most severe CT (computed tomography)-identified brain damage was located in the right parieto-temporal lobe. In the first months following the injury, the pattern of reading errors was similar to that associated with deep dyslexia. However, nonlexical derivation of phonology from print was not abolished. As the patient's ability to associate letter patterns with sounds improved, oral reading also improved. Although he no longer produced semantic errors in oral reading, he continued to produce oral reading errors that were visually and phonologically related to the targets. Four months after the injury, the error pattern observed in the patient's oral reading was consistent with very mild surface dyslexia. The significance of these observations to dual-deficit models of acquired dyslexia is discussed, as are their implications for rehabilitation.
