Developmental Language Disorder (DLD)

Also called developmental language disorder (ICD-11 6A01.2). That is the name used in diagnostic manuals and on most official paperwork.

Developmental Language Disorder, or DLD, means a child finds it hard to understand or use spoken language, and there is no other clear reason for it. It is common: on average about two children in every class of 30.

Applies across the UK

DLD is a type of speech, language and communication need that affects the way children understand and use language. RADLD puts it simply: DLD is diagnosed when children fail to acquire their own language for no obvious reason. On average Descriptive range The words a report uses to sum up a score, like 'average' or 'extremely low'. Tests draw these bands in their own places, so the same word can mean different scores. Read the full definition of Descriptive range , two children in every class of 30 will have DLD severe enough to hinder academic progress. The Royal College of Speech and Language Therapists puts the figure at 7.58% of children.

The 'no obvious reason' part is the key to the diagnosis. If the language difficulty is linked to something identifiable, such as autism Autism Autism is a difference in how the brain develops. It shapes how an autistic child sees and experiences the world, how they communicate, and how they respond to things like noise, light and touch.

The name is not accidental and it is not a euphemism. In 2016 an international group of 57 experts, the CATALISE panel Panel A meeting where professionals decide things like funding or a place on a waiting list. Parents are not in the room, but you can still ask how a decision was made. Read the full definition of Panel , reached consensus on the criteria used for children's language difficulties, and agreed on the terms 'language disorder' and 'developmental language disorder'. That consensus replaced a mess of earlier labels, including 'specific language impairment Impairment The word services use for how much something gets in the way of daily life. A diagnosis usually needs proof of this, not just a list of traits. Read the full definition of Impairment '. Because so many children with DLD were going unrecognised under inconsistent names, the advocacy community campaigns for the term DLD itself to be used and recognised.

Other words for this

  • You might have heard specific language impairment (SLI)

    Direction: SLI is superseded by DLD. SLI was the earlier, mainly North American term. Parents with older reports or older siblings may have met it.

  • You might hear language delay

    Not the same thing. A delay implies catching up. DLD is persistent. Worth stating explicitly for parents. The delay/disorder distinction was NOT verified verbatim in this pass.
