DLD

A condition affecting language acquisition despite normal cognitive function, hearing, and social interaction opportunities. Diagnosed when language delays are significant and not explained by other disorders.

What are common language difficulties in DLD?

DLD can manifest in challenges with vocabulary (semantics), sentence structure (syntax), word forms (morphology), and social communication (pragmatics).

How is DLD different from Autism Spectrum Disorder (ASD)?

Both DLD and ASD may involve language delays, but ASD also involves deficits in social communication and behavior that are not typical of DLD.

How does DLD differ from Intellectual Disability (ID)?

DLD specifically affects language skills, while ID impacts multiple developmental areas, including cognitive, motor, and language.

What is Language Delay?

A slower-than-typical language development, often seen in younger children who eventually catch up to age-appropriate levels without long-term consequences.

What is Language Difference?

Language skills deviate from the norm due to cultural, linguistic, or dialectical factors, not a disorder. Examples include bilingual children using different language structures.

What is Language Disorder?

A long-term, persistent difficulty with language acquisition, involving substantial impairment across contexts, not due to environmental factors, hearing loss, or other medical conditions.

How is DLD different from Hearing Impairment?

DLD is not caused by hearing loss, but rather by a neurological basis affecting language development. Difficulties in children with hearing impairments stem from inadequate auditory input.

Cognitive Theory of Language Disorders

This theory suggests that language disorders arise from underlying cognitive impairments, such as deficits in working memory, attention, or processing speed. Difficulties with language are seen as a symptom of broader cognitive weaknesses.

Genetic Component of DLD

Research shows a strong genetic component in DLD, as identical twins are more likely to both have DLD than non-identical twins. Studies have identified specific genes that may be linked to language disorders.

Study Notes

Developmental Language Disorder (DLD)

  • DLD, formerly SLI, is a language disorder affecting language acquisition despite normal cognitive, hearing, and social abilities.
  • Diagnosis occurs when significant language delays are present beyond those explained by other disorders (like autism, intellectual disabilities, or hearing loss).
  • DLD encompasses difficulties in vocabulary (semantics), sentence structure (syntax), word forms (morphology), and social communication (pragmatics).

Differentiating DLD from Other Conditions

  • Autism Spectrum Disorder (ASD): Both may involve language delays, but ASD also includes social communication and behavioral deficits not typical in DLD.
  • Intellectual Disability (ID): Children with ID have developmental delays across multiple areas, including language, whereas DLD involves specific language difficulties.
  • Hearing Impairment: Unlike DLD, hearing impairments cause language difficulties due to auditory input deficits.

Types of Language Differences/Disorders

  • Language Delay: Temporary, slow language development that often resolves as the child catches up with peers.
  • Language Difference: Language deviating from the norm due to cultural, linguistic, or dialectical differences.
  • Language Disorder (e.g., DLD): Persistent, long-term language difficulties beyond normal developmental patterns, not due to environment, hearing loss, or other medical conditions.

Theoretical Perspectives on DLD

  • Cognitive Theory: DLD stems from underlying cognitive impairments in working memory, attention, or processing speed.
  • Neurobiological Perspective: DLD arises from atypical brain structure or function in language-processing areas like Broca's area.

Multi-Factorial Nature of DLD

  • DLD results from a combination of genetic, environmental, and neurobiological influences, not a single cause.
  • Evidence supports a genetic component, demonstrated in twin studies and identified gene variations (e.g., FOXP2).

Prevention of DLD

  • Primary Prevention: Intervening before the disorder occurs, targeting at-risk populations (e.g., language enrichment programs).
  • Secondary Prevention: Early identification and intervention after the disorder shows signs but before severe outcomes (e.g., screening toddlers for language delay).

Identifying DLD in Toddlers

  • Difficulties: Identifying DLD in toddlers, especially with Late Language Emergence (LLE) cases, presents challenges due to catch-up potential.
  • Distinguishing from LLE: Persistent delays over time (adjusting for age) and social communication difficulties are key indicators of DLD.

Language Deficits in School-Aged Children with DLD

  • Morphology: Difficulty with word forms (plurals, verb tenses, possessives).
  • Syntax: Challenges with sentence structure (word order, complex sentences).
  • Semantics: Reduced vocabulary, difficulty understanding words in context, abstract language issues.
  • Pragmatics/Discourse: Challenges in social communication, conversation turns, greetings, narratives.

Impact of DLD on Literacy Development

  • The Simple View of Reading: Reading comprehension depends on decoding and language comprehension.
  • Decoding: DLD impacts phonological awareness, affecting word recognition.
  • Language Comprehension: DLD affects the ability to understand complex written language, impacting understanding of text.
