DLD stands for Developmental Language Disorder, which is a communication disorder that interferes with learning, understanding, and using language. It is a neurodevelopmental disorder that emerges in early childhood and persists into adulthood. DLD affects about 1 in 14 children in kindergarten, and it is one of the most common developmental disorders. Children with DLD have language abilities that fall behind those of other children their age, even though they are often just as smart. DLD can affect a child’s speaking, listening, reading, and writing. It is not caused by brain damage, and it is not the same thing as a learning disability, but it is a risk factor for learning disabilities since problems with basic language skills affect classroom performance. The exact causes of the brain differences that lead to DLD are unknown, but it is believed to be caused by complex interactions between genes and the environment that change brain development. DLD is associated with an elevated risk of social, emotional, and mental health concerns. Although DLD has been used for many years, it has been less common than the term specific language impairment (SLI), which has been widely adopted, especially in North America. However, the definition of SLI was rejected by the CATALISE panel because it was seen as overly restrictive in implying that the child had relatively pure problems with language in the absence of any other impairments.
