Developmental Language Disorder

Developmental Language Disorder (DLD) is a common, lifelong neurodevelopmental condition that causes significant, ongoing difficulties in understanding and/or using spoken or written language. It is a “hidden disability” often misunderstood as shyness or a behavioral problem, but it affects approximately two children in every classroom of 30, making it five times more prevalent than autism. Some key characteristics of DLD, and ways to assist, are as follows.

DLD is a result of differences in brain development, often running in families due to complex genetic and environmental interactions. It is not caused by lack of exposure to language, hearing loss, or intellectual disability. The language difficulties can significantly impact education, social interactions, emotional well-being, and future employment prospects.

While DLD is a lifelong condition, appropriate support and intervention from a speech-language pathologist can help individuals build communication skills and thrive. Signs of DLD vary depending on age and individual, but common indicators include: 

  • Late talking and difficulty learning new words.
  • Struggling to put words into sentences or using simple, ungrammatical sentences (e.g., “Me jump here” instead of “I jumped here”).
  • Difficulty understanding spoken language, following complex directions, or answering questions.
  • Trouble telling stories in a clear, organized way.
  • Word-finding difficulties (words feel “right on the tip of the tongue”).
  • Challenges with reading and writing which can go unnoticed until academic demands increase in later school years. 

DLD is typically diagnosed by a speech-language pathologist (SLP) after a comprehensive evaluation that may include standardized tests, observations, and detailed history from parents and teachers. There is no single medical or genetic test for DLD. 

Treatment usually involves working with an SLP to develop strategies and therapy programs tailored to the individual’s specific needs, which can help with: 

  • Building social skills.
  • Improving reading, speaking, and writing abilities.
  • Organizing thoughts and ideas. 

DLD is a neurodevelopmental condition with strong genetic influences, caused by differences in brain development. Parenting styles do not cause DLD, but parents can be part of the solution by using strategies to enhance communication at home. DLD is a lifelong condition. While language skills improve with appropriate therapy and support, the challenges do not simply disappear with age. Adults with DLD continue to manage the condition and may require ongoing accommodations.

DLD affects individuals at all levels of intellectual ability. People with DLD often have average or above-average intelligence, but they struggle to express what they know due to language processing difficulties. Individuals with DLD may appear quiet or reserved, but this is usually a coping mechanism because communication can be anxiety-inducing or exhausting. It is a language difficulty, not a personality trait.

Research consistently shows that bilingualism does not cause DLD or language delays. DLD affects both monolingual and bilingual individuals. There are many social and cognitive benefits to being bilingual, and families should continue to speak their native languages at home. 

Services and support for Developmental Language Disorder (DLD) typically involve speech-language therapy, educational accommodations, and local and national support resources. Early intervention is highly recommended for the best outcomes but help at any age can make a significant difference. For more information and resources, visit the DLDandMe or RADLD websites. 

In schools and workplaces, simple strategies can make a big difference. These include using simple, clear language, giving extra time for processing, using visual support, and breaking down instructions into smaller chunks. 

Recognizing DLD as a biological condition shifts the focus from parental guilt or individual shortcomings to a collaborative support effort. Encourage open conversations about DLD in all environments to foster empathy and ensure people feel comfortable asking for support and accommodation.
