Childhood Apraxia of Speech

Overview

Childhood apraxia of speech (CAS) is a rare speech disorder characterized by difficulties in controlling the movements of the lips, jaw, and tongue during speech. In CAS, the brain struggles to plan and coordinate the muscle movements required for proper speech, resulting in incorrect or distorted sounds and words. It is not caused by muscle weakness or tone problems. CAS often occurs without an observable brain abnormality, but can be related to brain conditions, injuries, genetic disorders, or metabolic conditions. Treatment typically involves speech therapy with a speech-language pathologist, who helps the child practice and develop correct speech movements and patterns. If you suspect your child has CAS, it is important to consult with a speech-language pathologist for an evaluation and appropriate treatment plan.

Understanding the disease

Symptoms

Symptoms of childhood apraxia of speech (CAS) may include:

• Babbling less or making fewer vocal sounds than typical between ages 7 to 12 months.
• Speaking first words late, typically after ages 12 to 18 months old.
• Using a limited number of consonants and vowels.
• Often leaving out sounds when speaking.
• Using speech that is hard to understand.
• Trouble moving smoothly from one sound, syllable, or word to another.
• Pauses between syllables or words.
• Voicing errors, such as "pie" sounding like "bye."
• Difficulty controlling the lips, jaws, and tongues when speaking.
• Reduced vocabulary or trouble with word order. These symptoms are usually noticed between ages 18 months and 2 years. If you notice any speech problems in your child, it is important to have them evaluated by a speech-language pathologist as soon as possible.

Risk Factors

Risk factors for developing childhood apraxia of speech (CAS) include changes in the FOXP2 gene, which may affect how certain nerves and pathways in the brain develop. Other genes may also impact motor speech development. However, often a cause cannot be determined. CAS can also result from brain conditions or injury, such as a stroke, infections, or traumatic brain injury. It may also occur as a symptom of a genetic disorder, syndrome, or metabolic condition.

Development

Childhood apraxia of speech (CAS) is a speech disorder that occurs when the brain has difficulty planning and controlling the movements needed for speech. This can result in problems with pronunciation, word formation, and difficulty speaking at the proper speed and rhythm. CAS can be caused by a variety of factors, including brain conditions or injury, genetic disorders, and metabolic conditions. The symptoms of CAS can vary depending on the child's age and the severity of the speech problems. If you suspect your child has CAS, it is important to have them evaluated by a speech-language pathologist as early intervention can help with the development of effective speech and communication skills.

Assessment and Diagnosis

Triage

If you suspect childhood apraxia of speech (CAS) in your child, it is recommended to consult with a healthcare professional or a speech-language pathologist as soon as possible. Early diagnosis and intervention are crucial in managing and treating CAS effectively. Since the symptoms of CAS may also be present in other speech or language disorders, it is important to consult with a professional who can help distinguish between the different types of speech disorders and provide an accurate diagnosis.

Diagnosis

To diagnose childhood apraxia of speech (CAS), a speech-language pathologist conducts a comprehensive evaluation of the child's symptoms, medical history, and speech production. The evaluation consists of examining the muscles used for speech, assessing language skills, and determining the pattern of problems exhibited by the child. Tests may include hearing tests, oral-motor assessments, and observing the child's speech during different tasks. A diagnosis is not based on a single test or observation but on the overall pattern of speech difficulties. It may be challenging to diagnose CAS in children who speak very little or have trouble interacting with the speech-language pathologist. If you suspect your child may have CAS, it's important to consult a speech-language pathologist for an evaluation.

Management and Treatment

Treatment

The treatments for childhood apraxia of speech (CAS) primarily involve speech therapy. A speech-language pathologist works with the child to teach them how to produce sounds, syllables, and phrases correctly. The therapy focuses on improving the child's motor planning skills and coordination of the muscles involved in speech production. Parents can also engage in therapeutic activities at home to reinforce the skills learned during therapy. Early intervention and ongoing therapy are crucial for optimal results.

Preparing for medical consultation

To prepare for an appointment for childhood apraxia of speech, you should:

1. Gather information: Write down any symptoms your child is experiencing, including any that may seem unrelated to speech issues. Bring a list of all medicines, vitamins, or supplements your child is taking.
2. Prepare questions: Compile a list of questions to ask the speech-language pathologist, such as "Does my child have CAS or any other speech or language problems?", "How is CAS different from other types of speech disorders?", "Is my child's condition going to improve?", "What treatments are available, and which do you recommend?", "What can I do at home to help my child?", and "Are there any brochures or other printed material that I can take home with me? What websites do you recommend?"
3. Gather documentation: Bring a copy of a recent progress report, and if your child has already been seen by a speech-language pathologist, bring their individual education plan if you have one.
4. Be prepared to discuss your child's history: Be ready to answer questions about when you first had concerns about your child's speech development, and if your child babbled typically.
5. Consider support groups: Look into support groups in your area, such as the Apraxia Kids website. Remember to be proactive and ask questions during your appointment whenever you need clarification or have additional concerns. This will ensure you get the most out of your appointment and gain a better understanding of your child's diagnosis and recommended treatment plan.
