[The prospects of the future study and medical practice].

It is thought that dyslexia is caused by brain dysfunction--specifically, impairment of phonological processing. Dyslexia is classified into neurodevelopmental disorder in DSM-5 and is described as an alternative term for specific learning disorder that includes reading impairment. It seems that dyslexia will be recognized as a separate clinical entity. As in our country, clinical research for diagnosis and treatment is continually progressing. Our original reading aloud test is recognized as an official examination for dyslexia diagnosis and is indicated as a mark of the fee-for-service. The time has come when we must regard this disorder not only as a special needs education issue but also as a medical subject.
