Expressive language disorder - developmentalDefinition: Developmental expressive language disorder is a disorder in which a child has lower-than-normal proficiency in vocabulary, the production of complex sentences, and recall of words.
Alternative Names: Language disorder - expressive
Causes, incidence, and risk factors: Approximately 3 to 10% of all school-age children have expressive language disorder. The causes of this disorder may vary, or may be unknown. Cerebral damage and malnutrition may cause some cases -- perhaps in combination with genetic factors.
Symptoms: - Below-average vocabulary skills
- Improper use of tenses (past, present, future)
- Problems in the production of complex sentences
- Problems in recalling words
Signs and tests: Standardized expressive language and non-verbal intellectual tests should be conducted if an expressive language disorder is suspected. Testing for other learning disabilities may also be needed.
Treatment: Language therapy is the best method to remedy this type of disorder. The goal of this therapy is to increase the number of phrases a child can use. This is done by using block-building techniques and speech therapy.
Expectations (prognosis): The degree of recovery depends on the severity of the disorder. With reversible factors like vitamin deficiencies, there may be nearly full recovery.
Complications: - Problems with socialization
- Learning problems
- Low self-esteem
Calling your health care provider: Parents who are concerned about a child's language development should have the child tested.
Prevention: Good nutrition during pregnancy and early childhood and prenatal care may help. Other methods of prevention are unknown.
