Here we present the case of a child who visited the university with the chief complaint of dysarthria. He initially suffered from dysarthria and mild mental retardation, but later developed serious problems with reading and writing. We considered his phonological processing ability and a possible connection with developmental dyslexia. The child was a 7-year-old boy who was in second grade at a regular elementary school. At 5 years of age, he was diagnosed with a submucous cleft palate and underwent surgery to correct this. After surgery, he was evaluated and started receiving training. He was diagnosed with language delay due to mild mental retardation and dysgraphia accompanying underdeveloped dysarthria, and received 7 months of ST training. In the re-evaluation that followed his training, he was not seen to have general mental retardation, but his problems with reading and writing became apparent. Cross-examining his problems reading and writing with a triangle model and visual cognition processes suggested a problem with bilateral processing of writing and phonology. This was a decoding problem, which is the basic condition of a patient with developmental dyslexia. The boy's core problem thus appeared to be a phonological type of developmental dyslexia.
