Mixed receptive-expressive language disorder
Definition
Mixed receptive-expressive language disorder is a language disability which causes impairment of both the understanding and the expression of language.

Causes
3-5% 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

  • Problems with language comprehension
  • Problems with language expression
  • Speech contains many articulation errors
  • Difficulty recalling early sight or sound memories

Exams 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.

All children diagnosed with this condition should be seen by a neurologist or developmental pediatric specialist to determine if the cause can be reversed.

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.
