Characteristics of Childhood Apraxia of Speech (CAS): Childhood Apraxia Of Speech Screener
Childhood Apraxia of Speech (CAS) is a speech disorder that affects the ability to plan and produce speech sounds accurately. It is a neurological disorder that affects the way the brain sends signals to the muscles used for speech.
Primary Features and Symptoms of CAS
The primary features of CAS include:
- Difficulty producing speech sounds accurately, resulting in distorted or unclear speech
- Inconsistent speech production, with the same word being pronounced differently at different times
- Prolonged speech attempts, with effortful and slow speech
- Difficulty with speech prosody, including intonation, stress, and rhythm
- Oral motor difficulties, such as difficulty moving the lips, tongue, and jaw
How CAS Differs from Other Speech Disorders
CAS differs from other speech disorders in several ways:
- In CAS, the primary difficulty is in planning and producing speech sounds, rather than in understanding or using language.
- CAS is not a progressive disorder, meaning that it does not typically worsen over time.
- CAS is not associated with intellectual disability or hearing loss.
Specific Speech Difficulties Associated with CAS
Children with CAS may have difficulty with the following specific speech sounds:
- Consonants that require precise placement of the lips, tongue, and jaw (e.g., /p/, /b/, /t/, /d/)
- Consonant blends (e.g., /sp/, /st/, /bl/)
- Vowels that require precise shaping of the lips and tongue (e.g., /i/, /u/, /o/)
Screening Tools for CAS
Purpose and Importance of CAS Screening
CAS screening is important because it can help identify children who may need further evaluation and intervention. Early identification and intervention can lead to improved speech outcomes for children with CAS.
Different Screening Tools Available for CAS
There are several different screening tools available for CAS, including:
- Goldman-Friscoe Test of Articulation-2 (GFTA-2)
- Apraxia Screen for Children (ASC)
- Screening Test for Apraxia of Speech (STAS)
Procedure for Administering a Specific CAS Screening Tool
The administration of a specific CAS screening tool will vary depending on the tool being used. However, general procedures include:
- Observing the child’s spontaneous speech
- Administering specific tasks that target speech sound production
- Assessing the child’s ability to imitate speech sounds and words
Interpretation of CAS Screening Results
How to Interpret the Results of a CAS Screening, Childhood apraxia of speech screener
The results of a CAS screening should be interpreted by a qualified speech-language pathologist. The speech-language pathologist will consider the child’s performance on the screening tool, as well as their observation of the child’s speech.
Criteria for Identifying Children Who May Need Further Evaluation
Children who meet the following criteria may need further evaluation for CAS:
- A score below the cut-off score on a standardized CAS screening tool
- Difficulty producing speech sounds accurately, as observed by a speech-language pathologist
- Other signs and symptoms of CAS, such as inconsistent speech production or difficulty with speech prosody
Limitations of CAS Screening Tools
It is important to note that CAS screening tools are not diagnostic tools. A diagnosis of CAS can only be made by a qualified speech-language pathologist after a comprehensive evaluation.
Differential Diagnosis of CAS
Other Conditions that Can Resemble CAS
Several other conditions can resemble CAS, including:
- Dysarthria
- Childhood speech sound disorder (CSSD)
- Language impairment
How to Differentiate CAS from These Conditions
CAS can be differentiated from these other conditions by considering the following factors:
- Dysarthriais a speech disorder caused by damage to the muscles or nerves involved in speech production. Children with dysarthria typically have difficulty with both speech sound production and speech prosody.
- CSSDis a speech disorder that affects the ability to produce speech sounds accurately. Children with CSSD do not have difficulty with speech prosody or with planning speech movements.
- Language impairmentis a disorder that affects the ability to understand or use language. Children with language impairment may have difficulty producing speech sounds accurately, but they typically do not have difficulty with speech prosody or with planning speech movements.
Specific Diagnostic Tests that May Be Used
Specific diagnostic tests that may be used to differentiate CAS from other conditions include:
- Orofacial examination
- Speech sound analysis
- Language assessment
Importance of Early Intervention for CAS
Benefits of Early Intervention for Children with CAS
Early intervention for children with CAS can lead to improved speech outcomes. Early intervention can help children with CAS to:
- Produce speech sounds more accurately
- Improve their speech prosody
- Develop better language skills
- Increase their confidence and self-esteem
Types of Therapies Available for CAS
There are several different types of therapies available for CAS, including:
- Speech sound production therapy
- Speech prosody therapy
- Language therapy
Where to Find Resources for Early Intervention
Parents of children with CAS can find resources for early intervention through:
- Their local school district
- State early intervention programs
- Private speech-language pathologists
