Apraxia of speech is a motor speech disorder that disrupts the brain’s ability to coordinate the precise movements needed for clear speech. Unlike other speech disorders, it is not due to muscle weakness but rather challenges in planning and sequencing speech sounds. In children, this condition is known as childhood apraxia of speech (CAS), which can significantly affect communication if not identified early.

According to the American Speech-Language-Hearing Association (ASHA), children with CAS may:

• Struggle with consistent speech sound errors
• Have difficulty imitating words and sounds
• Show frustration when trying to speak
• Display altered speech rhythm, leading to slow or choppy speech
• Have a limited range of consonants and vowels, sometimes with distorted sounds
• Exhibit visible effort or “groping” movements when attempting speech

CAS may occur without a known cause, result from neurological events (such as stroke or head trauma), or be associated with genetic conditions like fragile X syndrome, Rett syndrome, or Prader-Willi syndrome. It is estimated to affect 1–2 children per 1,000, with a higher prevalence in boys than girls.

At Manhattan Letters, our approach to treating CAS focuses on smooth transitions between sounds rather than isolated sound practice. This motor speech disorder-based method is key to improving speech clarity and fluency, allowing Manhattan children to develop more natural and coordinated speech patterns.

Diagnosing childhood apraxia of speech (CAS) requires a thorough evaluation by a skilled speech-language pathologist (SLP). At Manhattan Letters, we provide comprehensive assessments that include:

• Dynamic Speech Evaluations: Focused on motor planning and sequencing
• Multisensory Techniques: Utilizing visual, auditory, and tactile cues
• Comprehensive Speech Analysis: Identifying specific speech sound patterns
• Oral-Motor Assessment: Evaluating coordination and movement of the mouth and tongue for non-speech tasks

Our Manhattan-based SLPs are experienced in distinguishing CAS from other speech disorders, ensuring an accurate diagnosis and effective treatment tailored to the needs of Manhattan families.

Childhood Apraxia of Speech (CAS) is estimated to affect 1–2 children per 1,000 (0.1%–0.2%), with males being 2–3 times more likely to be diagnosed than females (Shriberg et al., 1997; Hall, Jordan, & Robin, 1993).

Despite its relatively low prevalence, CAS is often misdiagnosed, with research indicating that up to 75% of children diagnosed with CAS may actually have significant expressive language delays that resemble apraxia. Due to this, experts caution against diagnosing CAS too early.

Regardless of the diagnosis, early identification and appropriate intervention are essential. A qualified speech-language pathologist (SLP) with expertise in CAS and an evidence-based approach can ensure an accurate diagnosis and effective treatment tailored to the child’s needs.

Additionally, children with CAS are at higher risk for:

• Language delays
• Reading difficulties
• Spelling challenges

Comprehensive support is necessary to help children with CAS build strong communication and literacy skills.

At Manhattan Letters, our approach to treating Childhood Apraxia of Speech (CAS) focuses on smooth transitions between sounds rather than isolated sound practice. This motor speech disorder-based method is key to improving speech clarity and fluency, allowing children to develop more natural and coordinated speech patterns.

What is CAS? It’s a speech disorder where the brain has difficulty coordinating the movements needed for speech. This leads to:

• Inconsistent speech errors
• Disrupted prosody (irregular rhythm and stress)
• Visible frustration when speaking

Recognizing these early signs helps parents seek timely intervention, leading to better speech development outcomes.

A comprehensive assessment for Childhood Apraxia of Speech (CAS) includes several critical components to ensure accurate diagnosis and effective intervention.

• Speech and Language Evaluation – Assesses a child’s ability to produce sounds, syllables, and words, with a focus on imitation skills.
• Motor Speech Examination – Examines speech movements to identify challenges with motor planning.
• Dynamic Assessment – Observes how a child’s speech changes in response to different cues, such as visual, verbal, or tactile support.
• Prosody and Intonation Review – Evaluates speech rhythm, stress patterns, and overall melodic flow.
• Oral-Motor Assessment – Examines coordination and movement of the mouth and tongue for non-speech tasks.
• Phonological Analysis – Identifies patterns of sound errors to better understand the child’s speech development.

Timely and accurate identification of CAS provides significant benefits:

• Tailored Treatment – CAS requires a specialized therapy approach that focuses on motor planning and sequencing, rather than traditional articulation therapy.
• Avoiding Misdiagnosis – Research suggests that many children with CAS are initially misdiagnosed, which can delay effective intervention.
• Early Language Support – Since CAS affects speech production, early intervention is essential for fostering overall language development.
• Better Long-Term Progress – Addressing CAS early reduces the risk of persistent speech and communication challenges.

Experienced speech-language pathologists (SLPs) play a vital role in diagnosing CAS by:

• Distinguishing CAS from other speech disorders, such as phonological disorders or dysarthria.
• Using evidence-based assessment methods to ensure a precise diagnosis.
• Evaluating speech patterns in varied contexts to fully understand the child’s needs.

Following a CAS diagnosis, a personalized treatment plan is developed based on the child’s specific needs. Key aspects of CAS intervention include:

1. Intensive Therapy: Frequent, short sessions are often recommended for optimal progress.
2. Motor-Based Approaches: Interventions focusing on speech motor planning and programming, such as Dynamic Temporal and Tactile Cueing (DTTC) or Rapid Syllable Transition Treatment (ReST).
3. Multisensory Techniques: Incorporating visual, auditory, and tactile cues to support speech production.
4. Augmentative and Alternative Communication (AAC): Implementing AAC systems to support communication while working on speech skills.
5. Parent Involvement: Training parents in carry-over activities and communication strategies.

CAS is a complex motor speech disorder that is often misunderstood. Here are some common myths and the facts behind them:

Myth 1: Children Will “Grow Out of It”

Unlike some speech delays that improve naturally, CAS is a neurological condition that requires specialized and consistent speech therapy. Without targeted intervention from experienced professionals like those at Manhattan Letters, children with CAS in Manhattan, NYC will continue to struggle with speech production.

Myth 2: CAS Is Just a Speech Delay

CAS is a motor planning disorder, meaning the brain has difficulty coordinating muscle movements for speech. This is different from a general speech delay, which typically involves slower language development rather than challenges with motor coordination.

Myth 3: CAS Only Affects Speech

While speech difficulties are the most obvious symptom, CAS can also impact:

• Expressive language development
• Fine motor skills
• Reading and spelling abilities
• Social-emotional development

Manhattan Letters offers holistic therapy approaches that address not only speech clarity but also these related developmental areas, providing comprehensive support to Manhattan families.

Myth 4: CAS Reflects Intelligence

CAS is a motor speech disorder, not an intellectual disability. A child with CAS may have difficulty forming words, but this does not indicate a lack of intelligence or cognitive ability.

Myth 5: CAS Is Caused by Muscle Weakness

Unlike disorders involving weak muscles, CAS results from neurological difficulties in planning and coordinating speech movements. The muscles themselves function properly, but the brain struggles to send the correct movement signals.

Myth 6: CAS and Dyspraxia Are the Same

Although both involve motor planning challenges, CAS affects speech coordination specifically, while dyspraxia is a broader condition that can impact movement in other areas of the body. Manhattan Letters provides accurate diagnoses and tailored therapy plans, ensuring Manhattan families receive the right support for their child’s specific needs in Manhattan, NYC.

Myth 7: Children with CAS Cannot Succeed Academically or Professionally

With early intervention and appropriate support from Manhattan Letters, children with CAS can develop strong communication skills and thrive in school, careers, and social environments. Our goal is to empower Manhattan families by providing the tools and strategies needed for lifelong success.

Myth 8: CAS Is Contagious

Speech disorders cannot be “caught” from others. CAS is a neurological condition that is not influenced by exposure to children with speech difficulties.

Myth 9: CAS Cannot Be Diagnosed Before Age 3

While diagnosing very young children can be complex, skilled speech-language pathologists (SLPs) at Manhattan Letters can often identify signs of CAS before age 3 using dynamic assessments and other evaluation methods. Early diagnosis allows Manhattan families to access effective speech therapy sooner, improving outcomes for children throughout Manhattan, NYC.

A comprehensive evaluation by an experienced speech-language pathologist is essential for identifying CAS early and ensuring the child receives effective, targeted therapy. If you have concerns about your child’s speech development, seeking an assessment as soon as possible can make a significant difference in their communication success.
