Childhood Apraxia of Speech

Childhood apraxia of speech is a type of speech disorder. It is present from birth. A child with this condition has trouble making sounds correctly and consistently. Apraxia is a problem with how the brain sends signals to the muscles used for speech. Childhood apraxia of speech can range from mild to severe. It’s not a common condition. It occurs more often in boys than in girls.

Understanding apraxia of speech

The speech centers of the brain help coordinate what a child would like to say. These parts of the brain send complex signals to the speech muscles of the face, tongue, lips, and soft palate. When the signaling works normally, a child can make all the sounds he or she needs.

With childhood apraxia of speech, something in this process goes wrong. The speech muscles work properly, and the child knows what he or she wants to say. But the brain has trouble working with the muscles to create the movements needed for clear speech.

Childhood apraxia of speech is not the same as developmental delay of speech. Delay is when a child follows a normal path of speech development at a slower rate.

What causes childhood apraxia of speech?

Researchers do not yet know what causes childhood apraxia of speech. It may be related to a child’s overall language development. Or it may be a problem with the brain’s signals to the muscles needed for speech. Childhood apraxia of speech may be a part of a larger disorder, such as:

  • Cerebral palsy

  • Autism

  • Epilepsy

  • Galactosemia

  • Certain mitochondrial disorders

  • Neuromuscular disorders

  • Other intellectual disability

The condition may run in families. Many children with the disorder have a family member with a speech disorder or a learning disability.

Signs of childhood apraxia of speech

Not all children with childhood apraxia of speech have the same signs. And not all speech experts agree on the core signs of the condition. Some possible signs include:

  • Difficulty putting sounds and syllables together in the correct order

  • Inconsistent errors in consonants and vowels when repeating sounds

  • Long pauses between sounds

  • Problems with “prosody.” This is the varying rhythms and tones that help express meaning (emotional content) of speech.

  • Understanding language much better than expressing it

Some children have additional signs, such as:

  • Delays in the full use of muscles in hands and feet (fine motor delays) 

  • Overall delayed language development

  • Problems with reading, writing, spelling, or math

  • Chewing and swallowing difficulties

The signs may vary with a child’s age. They also may be mild to severe. A child with a mild case of apraxia may only have trouble with a few speech sounds. A child with very severe apraxia may not be able to speak very well at all.

Diagnosing childhood apraxia of speech

Childhood apraxia is a very complex disorder. It can be difficult to diagnose. Because of this, a speech-language pathologist (SLP) may need to diagnose the condition. An SLP has a lot of experience with speech problems. This helps him or her to tell the difference between childhood apraxia and other kinds of speech conditions.

The SLP will ask about your child’s medical history. He or she will ask you about what signs of speech problems you note. The SLP may also need to rule out other possible causes. These may include muscle weakness, comprehension problems, or hearing problems.

You as a parent and the SLP may need to observe a child’s speech over a long period of time. Your child may also need language testing. For example, the SLP may ask your child to repeat a word several times. Or your child might need to repeat a list of words of increasing length. No medical test can be used to diagnose childhood apraxia of speech.

Treatment for childhood apraxia of speech

Speech-language therapy is the main treatment. There is no single method that treats apraxia, and SLPs often use a variety of methods. Speech therapy is tailored to each child. Your child may do exercises such as:

  • Speaking a word as an SLP touches your child’s mouth and chin while saying the same word

  • Touching his or her mouth or throat while making sounds

  • Repeating syllables, then words and sentences

  • Looking in the mirror while practicing speech 

A child will often need to start with regular, one-on-one speech therapy. The results of therapy vary for each child. Some children make more progress than others.

In severe cases, children may need to use other ways to express themselves for a while. For example, your child might need to use:

  • An informal sign language

  • A language notebook with pictures

  • A portable computer that writes and talks 

Your child may not need to use these tools long-term.

Some children may also be helped by working with other health care providers. These may include:

  • Occupational therapists

  • Developmental pediatricians

  • Special education specialists

Helping your child at home

Family support is a key part of treatment for a child with apraxia of speech. Parents and caregivers can help children to practice their speech. Your child’s speech therapist may give you exercises to practice with your child. This can help to improve your child’s progress.

You can also help by:

  • Not pressuring your child to speak

  • Showing patience when your child does want to speak

  • Be positive about your child’s efforts

  • Showing others how to be supportive of your child’s attempts to communicate

  • Be generally supportive and encouraging to your child
