Developmental Language Disorder (DLD) is one of the most prevalent language disorders, statistically affecting 1 in 14 children in a classroom setting. However, the symptoms of DLD are frequently obscured by other conditions, leading to misdiagnosis and, consequently, inappropriate treatment.
So, what exactly is DLD, and why is an accurate differential diagnosis essential for a successful treatment approach? Developmental Language Disorder is characterized by impaired language development that affects all components of language except one. Children with DLD experience challenges in phonology, morphology, syntax, semantics, and word retrieval, without the presence of co-occurring conditions such as autism spectrum disorder, intellectual disability, or hearing loss.
In our clinic, we created a unique treatment program to ensure your child overcomes struggles from a non-talker (level 1 of the general language delay) to a graduate from the level 4 of the general language delay, where the kiddo acquires all language components with occasional minor errors that could potentially hinder academic progress. The program is created on a linguistic framework to therapeutic interventions, based on the understanding that language is a dynamic, fluid system that cannot be mastered through mere memorization of verbal scripts or behavioral patterns.
DLD is classified as a neurodevelopmental disorder, primarily affecting the cortex, specifically the Broca’s and Wernicke’s areas of the brain. The disorder can be categorized into three types: expressive, receptive, and mixed developmental language disorders. Although the exact causes of DLD remain unclear, it is believed that factors such as hypoxia, traumatic childbirth, and even febrile episodes in infancy may contribute to its onset.
Due to the overlap in symptoms, DLD is often misdiagnosed as autism spectrum disorder (ASD), intellectual disability (ID), or childhood schizophrenia. However, DLD necessitates distinctly different treatment strategies to ensure success. When addressed appropriately, children with DLD can achieve significant progress and integrate into mainstream environments. Therefore, a differential diagnosis is of utmost importance.
Misdiagnosis is a significant concern in therapy, however, another critical issue is the delay in seeking help. Ideally, parents should request an evaluation and pursue treatment when their child is between 1.5 to 2.5 years of age. At this young age, the brain’s plasticity, the stage of language emergence, and the lower demands for language use facilitate a more effective intervention process, typically requiring 2-3 years of continuous, intensive support. This early intervention not only promotes progress but also mitigates potential psycho-emotional challenges and intellectual decline.
It is important to note that by the age of 5, children typically begin Kindergarten, where expectations for language use significantly increase. If you have concerns regarding your child’s early language development, it is essential to trust your instincts. Although it may be common for late talkers to be perceived as typical, “common” does not equate to “normal.” We encourage you to reach out for a phone or Zoom consultation, or to schedule an evaluation to either rule out any issues or to prepare for necessary actions.
