Developmental language disorder (DLD) has been known by several different names, including expressive-receptive language disorder, specific language impairment (SLI), and speech-language impairment.
Understanding Developmental Language Disorder (DLD)
Developmental language disorder (DLD) is a diagnosis given to individuals who experience significant difficulties with talking and/or understanding language. These challenges are not due to other conditions, making DLD a primary and distinct language impairment. While DLD is the current and preferred term, it encompasses conditions previously identified by different names.
Historical Terminology for DLD
Over time, the understanding and classification of language difficulties have evolved, leading to changes in terminology. The following terms were previously used to describe what is now known as Developmental Language Disorder:
- Expressive-Receptive Language Disorder: This term highlighted difficulties in both expressing thoughts through language (expressive) and comprehending spoken or written language (receptive).
- Specific Language Impairment (SLI): This term emphasized that the language difficulties were specific, meaning they were not attributable to other developmental conditions, hearing loss, or intellectual disabilities.
- Speech-Language Impairment: This broader term could refer to difficulties in speech production, language comprehension, or language expression.
The adoption of Developmental Language Disorder (DLD) as the standard term aims to provide a clear and consistent diagnosis for these persistent language problems, reflecting current scientific understanding and promoting better recognition and support for affected individuals.
