Neurodiversity and Co-occurring differences

Developmental Language Disorder (DLD)

Developmental Language Disorder (DLD) was previously known as Specific Language Impairment (SLI) it is a type of speech, language and communication need (SLCN).

Children with DLD are usually as able and healthy as other children in all ways, with one exception; they have enormous difficulty talking and understanding language.

DLD is a very broad category, with some children having mild problems that are short-lived. Others have severe and persistent difficulties with both understanding and talking. These difficulties are not associated with other conditions, such as cerebral palsy, hearing impairment or autistic spectrum disorders. Children with DLD are often as clever as any other child of their age but they still have difficulties with speech and language.
