Definition
Mixed receptive-expressive language disorder is a language disability which causes impairment of both the understanding and the expression of language.Causes, incidence, and risk factors
Three to five percent of all children have either receptive or expressive language disorder, or both. These children have difficulty understanding speech (language receptivity) and using language (language expression). The cause is unknown, but there may be genetic factors, and malnutrition may play a role.
Problems with receptive language skills usually begin before the age of 4. Some mixed language disorders are caused by brain injury and these are sometimes misdiagnosed as developmental disorders.
Symptoms
Signs and tests
Standardized receptive and expressive language tests can be given to any child suspected of having this disorder. An audiogram should also be given to rule out the possibility of deafness, as it is one of the most common causes of language problems.
Treatment
Speech and language therapy are the best approach to this type of language disorder. Psychotherapy is also recommended because of the possibility of associated emotional or behavioral problems.
Expectations (prognosis)
The outcome varies based on the underlying cause. Brain injury or other structural pathology is generally associated with a poor outcome with chronic deficiencies in language, while other, more reversible causes can be treated effectively.
Complications
Difficulty understanding and using language can cause problems with social interaction and ability to function independently as an adult.
Calling your health care provider
Parents who are concerned about their child's acquisition of language should have the child tested. Early intervention will provide the best possible outcome.
