Apraxia

Summary Summary


Listen
Childhood apraxia of speech occurs in children and is present from birth. It appears to be more common in boys than girls.[1] Children with this condition have difficulty planning and producing the precise, refined, and specific movements of the tongue, lips, jaw, and palate that are necessary for intelligible speech.[2] In many cases, the underlying cause of childhood apraxia of speech is unknown (idiopathic).[1][2][3] Some cases are associated with a known neurological cause (such as intrauterine or early childhood stroke, infection, trauma, brain cancer or tumor resection, traumatic brain injury, etc.), and other cases occur as part of a complex neurobehavioral disorder (such as autism, epilepsy, fragile X syndrome, galactosemia, Rett syndrome, Prader-Willi syndrome or certain types of chromosome abnormalities).[1] In some cases, researchers have found alterations (mutations) in the FOXP2 gene or loss of genetic material involving this gene.[4] Treatment of childhood apraxia of speech involves speech therapy with a speech-language pathologist. Those with more severe cases will require more therapy than those with mild cases.[2] The goal of therapy is to increase speech production and intelligibility. In some cases, augmentative and alternative forms of communication may be needed.[3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from MedlinePlus Genetics.

Research Research


Listen

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Clinical Research Resources

  • ClinicalTrials.gov lists trials that are related to Childhood apraxia of speech. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.

    Please note: Studies listed on the ClinicalTrials.gov website are listed for informational purposes only; being listed does not reflect an endorsement by GARD or the NIH. We strongly recommend that you talk with a trusted healthcare provider before choosing to participate in any clinical study.

Organizations Organizations
