What is Developmental Language Disorder (DLD)?

Developmental Language Disorder (DLD) is a neurodevelopmental disorder characterized by significant and persistent difficulties in developing language skills appropriate for an individual's age.

DLD refers to language problems that cannot be explained by other biomedical conditions (such as intellectual disability, autism spectrum disorder, hearing loss, or brain injury).

These children may experience difficulties in the following areas:

  • Receptive language (comprehension)
  • Expressive language (speech)
  • Grammar usage
  • Vocabulary knowledge
  • Organization of narrative/discourse

How Common is DLD?

Research shows that it can be seen in approximately 1 in 14 children during the preschool period. Although it is more common than autism, public awareness remains low.

The impact of DLD is not limited to language; it can also affect social, academic, and emotional development.

What are the Symptoms of DLD?

In the Preschool Period:

  • History of late talking
  • Significant limitations in vocabulary
  • Difficulty forming sentences
  • Inability to use grammatical markers/suffixes
  • Difficulty understanding complex instructions
  • Inability to narrate events in a logical sequence

In School-Age Children:

  • Reading and writing difficulties
  • Decrease in academic achievement
  • Difficulty following verbal instructions
  • Problems with storytelling and written expression
  • Difficulty in social communication

What Causes DLD?

The exact cause of DLD is unknown. However, research suggests there may be a strong genetic predisposition.

Important Note: Bilingualism does not cause DLD.

The Evaluation Process

  1. Detailed developmental history
  2. Play-based observation
  3. Standardized language tests
  4. Criterion-referenced assessment
  5. Review of audiological and neurological reports if necessary

How Does DLD Therapy Work?

The therapy process is planned according to the child's age, specific needs, and language profile characteristics.

Early Intervention Goals:

  • Expanding vocabulary
  • Teaching grammatical structures
  • Improving sentence formation skills
  • Supporting social communication skills

Goals for School-Age Children:

  • Academic language support
  • Support for reading and writing skills
  • Understanding verbal instructions
  • Discourse/Narrative organization

Who is Part of the Intervention Team?

  • Speech and Language Therapist
  • Child Neurology / Psychiatry
  • Audiologist
  • Special education specialist when necessary

However, the most important member of the team is the family.

The Importance of Early Intervention

DLD can be a lifelong condition. However, with early and regular therapy:

  • Academic success can be improved
  • Social adjustment can be strengthened
  • Emotional problems can be reduced
  • Functional independence can be increased

Developmental Language Disorder is not just "late talking." It is a different way the language learning system functions. If you have any doubts about your child's language development, it is recommended to seek an expert evaluation without delay.
