What is Specific Language Impairment
Specific language impairment (SLI) is a type of speech, communication, and language disorder that is characterized by difficulty with the acquisition and mastery of language skills not caused by known sensory, emotional, neurological, or other developmental delays. It is one of the most common learning disabilities among children. A study funded by the National Institutes of Health estimated that between 7-8% of 5-year-olds are affected by this disorder. It appears that 50-70% of children diagnosed with SLI have a genetic link to at least one other family member who has the disorder.
What are the Symptoms of Specific Language Impairment?
Children with SLI often exhibit a delay in speech and may not be able to talk until they are 2-years-old. At age 3 or 4, children with SLI may speak with limited vocabulary, but may not be understood. As children get older, they will have difficulty learning new words and making conversation.
