Understanding Dyslexia in the Context of Developmental Language Disorders.

This is a review and clinical synthesis, not a new experiment or treatment trial, so it does not directly test whether the recommended assessment or intervention changes outcomes. The overlap between dyslexia and developmental language disorder varies with diagnostic criteria, sample type and timing of measurement, so the same child may be classified differently across systems. Many cited studies used clinical or convenience samples and measured language and reading at one time point, making it hard to separate early language weakness from later effects of reduced reading experience. The clinical recommendations are the authors' interpretation of the evidence, not results of a tested protocol.

The article reports that the work was supported in part by National Institutes of Health grants.

Do not read this as saying that dyslexia is only a decoding problem or that normal standardized language scores rule out broader language needs. The review says children with dyslexia may have subclinical language deficits and should be assessed across multiple language domains.
