Language Difficulties in School-Age Children With Developmental Dyslexia

Area of Science:

• Child Development
• Neuroscience
• Education

Background:

• Developmental dyslexia (DD) is a common reading disability affecting 5-11% of children.
• Children with DD frequently have a history of early language delay (ELD) or impairments.
• Conflicting research exists on the link between ELD and current language difficulties in DD.

Purpose of the Study:

• To investigate the association between early language delay and current language abilities in children with reading difficulties.
• To examine the relationship between early language, current language, and reading skills.
• To compare language and reading skills across groups: DD, intermediate readers (IR), and skilled readers (SR).

Main Methods:

• Parental reports on early and current language ability were collected for school-age children.
• Children were assessed using quantitative language and reading skills tests.
• A sample of 674 children was divided into DD, IR, and SR groups.

Main Results:

• A significant association was found between DD and ELD, with DD/IR groups reporting later word acquisition.
• Children with DD exhibited significant language difficulties, correlating with low expressive and receptive language abilities.
• Early language skills were predictive of current language abilities, which in turn predicted reading skills.

Conclusions:

• Children with DD consistently experience language difficulties.
• Early language development is a significant predictor of later reading success.
• Early identification of language issues may aid in identifying children at risk for reading problems like DD.
