A communication disorder can involve hearing, voice, speech, language, or a combination.

More than 10% of children have a communication disorder. A disorder in one area of communication may affect another area. For example, hearing impairment disrupts the ability to adjust the pitch or tone of the voice and can lead to a voice disorder.

All communication disorders, including voice disorders, may interfere with performance at school and with social relationships.

There are several types.

Hearing impairment

Voice disorders

More than 6% of school-age children have a voice problem, most often hoarseness. These problems usually result from long-term overuse of the voice, speaking too loudly, or a combination. Many children with voice problems have small nodules on the vocal cords Vocal Cord Polyps, Nodules, Granulomas, Papillomas Vocal cord nodules, polyps, granulomas, and papillomas are noncancerous (benign) growths that cause hoarseness and a breathy voice.

It is not clear how much the voice problems contribute to causing nodules or how much the nodules contribute to causing voice problems.

Nodules usually resolve with voice therapy and only rarely require surgery.

Speech disorders

In these disorders, the production of a speech sound is difficult. As a result, children are less able to communicate meaningfully. About 5% of children entering the first grade have a speech disorder. Speech disorders include the following:

Language disorders

The ability to use, understand, or express language can be reduced in otherwise healthy children (called specific language impairment). Thus, the ability to communicate is greatly impaired, limiting educational, social, and vocational opportunities. This disorder occurs in about 5% of children and is more common among boys. Abnormal genes appear to play a role in many cases. Alternatively, language problems can develop because of another disorder, such as a brain injury Overview of Head Injuries Head injuries that involve the brain are particularly concerning.

Some children appear to recover on their own. Others need language therapy.

Diagnosis of Communication Disorders

To diagnose voice and speech disorders, doctors examine the mouth, ears, and nose. Hearing tests are done, and the nervous system is assessed. If a voice disorder is suspected, doctors may look at the voice box with a mirror or a thin, flexible viewing tube (called a nasopharyngolaryngoscope), which is inserted through the nose.

Language disorders are diagnosed by comparing the child’s language with that expected for children of the same age.

Most important, parents or caretakers should be alert for communication problems in children and should contact a doctor if they suspect such a problem. Checklists of communication developmental landmarks are available and can help parents and caregivers detect a problem. For example, if children cannot say at least two words by their first birthday, they may have a communication disorder.
