Definition of Developmental Language Disorder (DLD):
DLD is a primary language disorder, in the expressive and receptive spheres, which is observed by variable impairments affecting the development of more than one component of language: phonology, morphology, syntax, semantics and pragmatics.
In addition to a heterogeneity of the manifestations of this disorder from one individual to another, it is characterized, in the same individual, by its persistence, the variability of the clinical portrait over time, as well as by a high probability that there is little evolution without intervention. Developmental language disorder (dysphasia) is often accompanied by other signs and can also coexist with other impairments.
DLD has impacts that can impede the individual’s personal, social, academic and professional development and functioning. As a result, DLD (dysphasia) causes situations of disability and variable harm to the individual and those around him, depending on the circumstances and at all ages.
Summary explanation of the definition (lexicon)
PRIMARY: the manifestations of the disorder is observed first at the level of language; predominance of the language disorder
EXPRESSIVE SPHERE: can be affected isolated
EXPRESSIVE AND RECEPTIVE SPHERE: receptive is never affected isolated
DYSPHASIA: involvement of more than one component of language
A PERSON DIAGNOSED WITH DLD (DYSPHASIA) MUST HAVE A MINIMUM OF TWO CONDITION:
- If only one component is affected, then it is a disorder of phonology, morphology, syntax disorder, etc.
- Different profiles from one individual to another
- Different tables according to resources, context, severity
- The gap in language skills persists over time
- Language disorder is observed at different levels at each period of life.

Definitions of the various language issues:
The“ language delay ” is characterized, as its name suggests, by slower language development than expected. This delay may be present for one aspect of language or for several, for example comprehension, development of sounds or morphosyntax. The degree of damage can be variable, from mild to severe. A beautiful evolution is noticed when the child receives a targeted and regular stimulation.
“ Language disorder ”, on the other hand, represents a slower and atypical development of language. Impairment in different aspects of language vary and one cannot simply compare the development of child’s language to that of a younger child; atypical particularities may also be presents. The difficulties are persistent despite speech therapy following regular follow-up that the speech-language pathologist can make the speech-language pathology conclusion of a language disorder.
Developmental language disorder (dysphasia), affect the expressive sphere or and receptive spheres.It affects more than one component of language in a variable way:
phonology, morphology, syntax, semantics and pragmatics.
It seems that more boys than girl are affected. Let us only mention that in addition to abstraction disorder, there are generalization disorders and time perception disorders as well as occasionally hearing perception disorders.
The name of the language disorder has changed several times over the years.
Audio-mute, Dysphasia, Primary language disorder. The new name accepted by the OOAQ (Ordre des Orthophonistes et Audiologistes du Québec) is developmental language disorder (DLD), since september 22nd, 2017.
