As a parent, you know your child better than anyone. You notice the little things; the way they struggle to find the right words, how they get anxious when they don’t understand instructions, or how making friends feels harder than it should. Most people have heard of autism or ADHD. But did you know there’s another neurodevelopmental difference that is even more common and yet much less understood? It’s called Developmental Language Disorder (DLD), and it is thought to affect around two children in every classroom.
Despite this, DLD remains under-recognised and underdiagnosed. That means many children and young people are missing out on the support they need or may be receiving the wrong kind of help. The impact can be far-reaching, affecting not just learning but also friendships, mental health and overall wellbeing.
What is DLD?
DLD is a lifelong neurodevelopmental condition, a ‘brain difference’ that affects how children understand and use spoken language. It’s sometimes described as a kind of “verbal dyslexia”, because it primarily impacts the technical side of language; vocabulary, grammar, sequencing and processing.
Without tailored support, children with DLD may struggle to:
- Follow spoken instructions or understand complex questions.
- Recall and use vocabulary accurately (sometimes knowing the word, but not being able to ‘retrieve’ it).
- Put sentences together, sequence their thoughts, or use grammar consistently.
- Understand jokes, sarcasm or abstract language.
- Use language to manage emotions, regulate behaviour or build friendships.
How does DLD compare to Autism?
Children with DLD can sometimes be mistaken for children on the autism spectrum. This is partly because there are overlapping features, such as:
- High levels of anxiety
- Difficulty making or maintaining friendships
- Challenges with non-literal or abstract language
- Sensory differences
- Difficulties with working memory, auditory memory and processing
- Reduced attention and executive function
The difference is in the focus of the difficulties. Autism diagnoses are based mainly on the social use of language and non-verbal communication (such as eye contact, gesture and tone of voice). DLD on the other hand, primarily affects the technical use and understanding of language itself.
It’s also worth noting that many children with DLD have other co-occurring differences such as ADHD, dyslexia, or developmental coordination disorder (previously known as dyspraxia).
Why early diagnosis matters
Research shows that when children with DLD are identified and supported early, the results are powerful. Structured language therapy and personalised support strategies can:
- Reduce anxiety
- Improve confidence and self-esteem
- Unlock academic potential
- Help children develop a positive sense of identity
Understanding their own strengths and challenges also empowers children and young people with DLD to advocate for themselves, an important skill that supports wellbeing well into adulthood.
Get the Right Support
Every child deserves to feel confident expressing their thoughts, feelings and ideas. Recognising DLD is the first step toward making that possible. If some of the signs described here sound familiar, it’s important to seek guidance and get the correct diagnosis. At ISLTS, we offer:
- Specialist DLD assessment and diagnostic services
- Tailored therapy programmes
- Training for parents, teachers and professionals
