Disability History Month 2024: Highlighting Development Language Disorder (DLD)
In celebration of Disability History Month, we’re spotlighting Developmental Language Disorder (DLD), a hidden but impactful communication disability affecting people of all ages.
DLD involves significant challenges in learning, understanding, and using spoken language. Although the term "DLD" was formalised only in 2017, the condition itself has been recognised for centuries, previously known by various names such as specific language impairment, language delay, and expressive-receptive language disorder.
Five key facts about DLD:
- DLD is a hidden disability. Individuals with DLD may make more grammatical errors, use simpler language, or struggle with organising their thoughts in conversation—often in ways that are subtle to non-specialists.
- DLD appears in early childhood and lasts a lifetime.
- DLD affects people worldwide, regardless of language spoken.
- DLD has wide-reaching effects. It can impact social-emotional health, academic achievement, and career success.
- DLD is not caused by a lack of language exposure. Genetics and environmental factors together shape a person’s risk.
Understanding DLD:
DLD is influenced by multiple genetic and environmental factors. For instance, certain genetic mutations increase DLD risk, and factors such as premature birth can amplify this risk. However, no single cause defines DLD; rather, it's the interplay of genetic and environmental factors.
Neurological research suggests that DLD involves subtle differences in brain development, including gray matter proportions and variations in brain region sizes, which aren't usually visible in standard brain scans. Understanding these differences remains an ongoing area of scientific study.
Paul Man, Interim Locality Lead for Hammersmith and Fulham Education Speech and Tanguage Therapy (SLT) said:
"Developmental Language Disorder (DLD) is one of the most common yet under-recognised disabilities, affecting around 7% of the population.
"Raising awareness of DLD during Disability History month is vital because it highlights the often unseen challenges faced by individuals with language needs.
"Understanding and supporting DLD can lead to better educational, social, and employment opportunities for those affected. Through acknowledging DLD, we honour the diversity of communication needs and can work towards a more inclusive future for all".
