What are 3 key distinguishing features of CAS?

Consensus has been reached that three core features have diagnostic validity: (1) inconsistent error production on both consonants and vowels across repeated productions of syllables or words; (2) lengthened and impaired coarticulatory transitions between sounds and syllables; and (3) inappropriate prosody (ASHA 2007).

What is the most common cause of apraxia?

The most common causes of acquired apraxia are: Brain tumor. Condition that causes gradual worsening of the brain and nervous system (neurodegenerative illness) Dementia.

What is CAS childhood apraxia of speech?

Childhood apraxia of speech (CAS) is a speech disorder in which a child’s brain has difficulty coordinating the complex oral movements needed to create sounds into syllables, syllables into words, and words into phrases.

How do you test for CAS?

To diagnose CAS, an SLP will learn about your child’s history, including any known medical problems. The SLP will also test your child’s hearing, oral-motor skills and intonation (pitch) and the way they say sounds. The SLP will also test your child’s ability to speak by: Checking for signs of mouth muscle weakness.

What are 4 of the characteristics of apraxia of speech?

These hallmark characteristics include: Inconsistent speech sound errors on consonants and vowels, in repeated productions of syllables and words. Disrupted and/or lengthened co-articulatory transitions between sounds and syllables. Impaired prosody (or rhythm of speech)

What are the 3 types of apraxia?

Other types of apraxia include limb-kinetic apraxia (the inability to make fine, precise movements with an arm or leg), ideomotor apraxia (the inability to make the proper movement in response to a verbal command), ideational apraxia (the inability to coordinate activities with multiple, sequential movements, such as …

When can apraxia be diagnosed?

Children between ages 2 – 3 may also be difficult to firmly diagnose with CAS. Some can and some cannot. There is no strict age as to when a child can be diagnosed with CAS. The most important thing is that the child is able to fully participate in the tasks required by the SLP who is evaluating them.

How do you examine apraxia?

Testing for Apraxia of Speech

A speech-language pathologist can test your speech and language. This will help the speech-language pathologist decide whether you have apraxia or some other problem. The speech-language pathologist will look at how well you can move your mouth, lips, and tongue.

How do you assess for apraxia?

Its assessment involves asking the patient to cough or to click their tongue and to demonstrate how they would drink through a straw or blow out a match. While it can occur in isolation, it almost always coexists with apraxia of speech and/or dysphasia.

What brain damage causes apraxia?

Apraxia is usually caused by damage to the parietal lobes or to nerve pathways that connect these lobes to other parts of the brain, such as frontal and/or temporal lobes. These areas store memories of learned sequences of movements. Less often, apraxia results from damage to other areas of the brain.

What is the best treatment for apraxia?

Speech therapy. Your child’s speech-language pathologist will usually provide therapy that focuses on practicing syllables, words and phrases. When CAS is relatively severe, your child may need frequent speech therapy, three to five times a week. As your child improves, the frequency of speech therapy may be reduced.

What is speech apraxia caused by?

Damage to the parts of the brain that control how your muscles move causes apraxia of speech. Any type of brain damage can cause apraxia. This includes stroke, traumatic brain injury, dementia, brain tumors, and brain diseases that get worse over time.

Is there a cure for CAS?

While there is no CURE, regular and intensive speech therapy using the principles of motor learning that is accessed early in the child’s life/diagnosis is known to best treat CAS. This means consistent attendance to therapy where the Speech-Language Pathologist (SLP) has experience in treating CAS.

How does apraxia affect speech?

Distorting sounds. People with AOS may have difficulty pronouncing words correctly. Sounds, especially vowels, are often distorted. Because the speaker may not place the speech structures (e.g., tongue, jaw) quite in the right place, the sound comes out wrong.

Do children outgrow CAS?

Children with CAS won’t simply outgrow the condition, but over time and with regular (and often intensive) speech therapy, their speech is likely to improve. The speech pathologist will approach the treatment to address the specific motor planning difficulties that your child is experiencing.

Can a child have apraxia and not be autistic?

The 2015 publication reported that data from the study showed 63.6% of children who originally received an autism diagnosis also had apraxia; 36.8% of children with apraxia also had autism; 23.3% of children had neither; and 23.3% of children had both and were diagnosed for both at the same time.
