What is Apraxia?
The CAS Brain Connection
In CAS, the brain has difficulty communicating with the speech muscles. Normally, the brain is able to tell speech muscles exactly how to move to perform certain sounds. But with CAS, perfectly normal speech muscles fail to perform correctly because of miscommunication with the brain.
Your child’s tongue, jaw, and lips must move in a specific way to form accurate words and sounds. This also allows them to speak with the appropriate rhythm and speed. But the brain is the leader, in that it must send the correct directions to the speech muscles. So although the child’s speech muscles are healthy, there’s still a disconnect.
Speech therapy is a common treatment for any child with APRAXIA OF SPEECH. During therapy, a speech-language pathologist helps your child practice saying phrases, words, and syllables. This gives the child a safe and nurturing environment in which to improve their speech.
A child with APRAXIA OF SPEECH may exhibit several different symptoms or characteristics. The child’s age and severity of the condition commonly play a role in the symptoms the child displays.
Between the ages of 18 months to 2 years, a child with CAS might:
2. Speak their first words much later than other children of their age.
3. Have the ability to form very few consonants or vowel sounds.
Between the ages of 2 and 4, a child with CAS might:
2. Break words into distinct syllables instead of simply pronouncing the word.
3. Display distortions between consonants and vowel sounds.
Childhood apraxia of speech can lead to additional development problems. For example, a child might have difficulty with sentence word order. Or they might have difficulty developing their vocabulary.
Sometimes CAS is difficult to diagnose. This is because its symptoms can also indicate other types of language or speech disorders. If a child has symptoms found in CAS and other disorders, then it’s difficult to discover which disorder the child actually has.
There are markers that distinguish CAS from other speech disorders. But a child with CAS won’t necessarily display these markers. Some markers normally associated only with CAS include:
– Visibly struggling with the tongue, lips, or jaw to correctly pronounce words.
– Struggling to pronounce the correct vowel but consistently saying it incorrectly.
– Having trouble pronouncing the same word correctly when spoken several times in a row.
– Having difficulty pronouncing simple words, such as “cat” or “see”.
If your child struggles to make sounds but doesn’t struggle with muscle movement, they might have another type of disorder. Dysarthria, phonological, and articulation disorders are other speech disorders often confused with CAS.
Causes of Apraxia in Children
CAS can have several reasons but in most cases, its cause is undetermined. A child with CAS usually doesn’t have any signs of problems with the brain. However, the disorder is sometimes caused by a brain injury such as a stroke, head trauma, or infection.
Genetics or metabolic conditions are also sometimes at fault. For instance, children with galactosemia are more likely to develop CAS than other children. Galactosemia is a group of inherited disorders that hinders the body’s ability to produce and process energy from sugar.
A child with CAS can possibly outgrow the disorder as they develop. In some other speech or developmental disorders, the child might just develop slower than most children their age. But with CAS, the child will likely need prolonged speech therapy to progress in their development.
Complications Caused by CAS
A child with CAS might develop additional communication problems. Although these problems aren’t caused by CAS, they often go hand-in-hand with the disorder. For example, a child with CAS can struggle with writing, spelling, and reading. They may also have problems with coordination and fine motor skills.
The earlier your child begins treatment, the better. With childhood apraxia of speech, early intervention can reduce the risk of your child developing additional problems. If your child has speech problems, contact a speech-language pathologist for help.
