Developmental Language Disorder (DLD) is a communication condition that can affect children and persist into adulthood, impacting their ability to speak, listen, read, and write effectively. Many children start talking later than expected, but some continue to struggle significantly with language acquisition, which may indicate DLD, according to Dr. Mary Alt, a speech and language expert at The University of Arizona.
One of the earliest signs of DLD is late talking combined with the use of simple language structures. For example, a child with DLD might say "Him run" instead of "Look, the dog is running." Children who rely more on gestures than spoken language for communication may also show signs of difficulty with language learning, noted Dr. Jim Montgomery, a professor of communication sciences at Ohio University.
Dr. Alt's research tracking children who were late talkers at ages 2 to 3 found that over half of these children were later diagnosed with a learning disability, though DLD itself is a distinct condition. Children with DLD may face challenges in vocabulary acquisition, sentence construction, and organizing stories in speech or writing. The severity of symptoms can vary widely.
DLD is prevalent but often under-recognized. While it may run in families, the precise causes remain unknown and may involve a combination of genetic and other factors influencing brain development. Distinguishing DLD from related disorders such as dyslexia, which involves difficulty connecting speech sounds to letters and words, is important as both conditions can affect language skills.
Efforts are underway to develop better methods for early identification of DLD to provide timely support and interventions that can strengthen language abilities and improve learning outcomes.
