BACKGROUND: Childhood apraxia of speech (CAS) affects a child's ability to produce sounds and syllables precisely and consistently, and to produce words and sentences with accuracy and correct speech rhythm. It is a rare condition, affecting only 0.1% of the general population. 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)...

Purpose To compare performance between children with typical speech acquisition, phonological disorders, and childhood apraxia of speech for the variables overall articulatory accuracy and consistency of the Dynamic Evaluation of Motor Speech Skill - Brazilian Portuguese version (DEMSS-BR). Methods Study participants were 18 children of both genders aged 4 years and 6 months to 5 years and 8 months. The sample was divided into three groups: six children with typical speech acquisition (TSA), six children with phonological disorder (PD), and six individuals with childhood apraxia of speech (CAS)...

Syllable segregation is among the core diagnostic features of both childhood apraxia of speech and acquired apraxia of speech; however, little is known about the limen of perception of syllable segregation. The purpose of this research was therefore to explore adult listeners' auditory perception of within-word syllable segregation in trained and untrained adult listeners. Two experimental design studies, each with two phases, were conducted. Study one included 40 untrained listeners (aged 18-28 years), and study two included 5 trained listeners (10-25 years of experience)...

Purpose: A Phase I pilot study was designed to collect preliminary evidence on the use of the Kaufman Speech to Language Protocol (K-SLP; Kaufman, 2014) to treat children with childhood apraxia of speech. We hypothesized that the K-SLP approach would result in more accurate speech production in targeted words, whereas untrained (control) words and speech sounds would remain unchanged. Method: A single-case multiple-baseline across behaviors experimental design was used to see if experimental feasibility could be demonstrated...

Childhood apraxia of speech and oral dyspraxia are subtypes of dyspraxia: a neurological motor disorder with absence of neuromuscular deficits. The core impairment is in planning and/or programming spatiotemporal parameters of movement sequences, which results in errors in speech sound production and prosody, or in oral motor movements and gestures. Correct diagnostics and focus on differential diagnoses and co-morbidity are crucial, as treatment differs from other types of speech- and oral motor disorders...

In the absence of any known neurological condition, dyspraxia is the inability to plan and execute movement. This case report describes a girl with swallowing difficulties, who was diagnosed with oral dyspraxia, as all other possible explanations had been ruled out. A percutaneous endoscopic gastrostomy was performed at the age of 6.5 months, and as a five-year-old she was still dependent on supplementary nutrition through the tube, even though she had gradually learned to swallow. Her difficulties to correctly pronounce syllables and words were later diagnosed as childhood apraxia of speech, another subtype of dyspraxia...

Genetic investigations of people with impaired development of spoken language provide windows into key aspects of human biology. Over 15 years after FOXP2 was identified, most speech and language impairments remain unexplained at the molecular level. We sequenced whole genomes of nineteen unrelated individuals diagnosed with childhood apraxia of speech, a rare disorder enriched for causative mutations of large effect. Where DNA was available from unaffected parents, we discovered de novo mutations, implicating genes, including CHD3, SETD1A and WDR5...

Purpose: Childhood apraxia of speech (CAS) is hypothesized to arise from deficits in speech motor planning and programming, but the influence of abnormal speech perception in CAS on these processes is debated. This study examined speech perception abilities among children with CAS with and without language impairment compared to those with language impairment, speech delay, and typically developing peers. Method: Speech perception was measured by discrimination of synthesized speech syllable continua that varied in frequency (/dɑ/-/ɡɑ/)...

Recurrent deletions of a ~600-kb region of 16p11.2 have been associated with a highly penetrant form of childhood apraxia of speech (CAS). Yet prior findings have been based on a small, potentially biased sample using retrospectively collected data. We examine the prevalence of CAS in a larger cohort of individuals with 16p11.2 deletion using a prospectively designed assessment battery. The broader speech and language phenotype associated with carrying this deletion was also examined. 55 participants with 16p11...

This study examined changes in speech motor control across a movement transition between sounds within a motor learning task in children with apraxia of speech (CAS) and typical development (TD). It was investigated whether oral articulator movement was refined with practice and whether practice gains generalized to words not included in the practice session. A total of 16 children (ages 5-6) with CAS (n = 8) and TD (n = 8) participated in this study. Novel and real word tokens were produced at three time points...

Communication disorder is common in Koolen de Vries syndrome (KdVS), yet its specific symptomatology has not been examined, limiting prognostic counselling and application of targeted therapies. Here we examine the communication phenotype associated with KdVS. Twenty-nine participants (12 males, 4 with KANSL1 variants, 25 with 17q21.31 microdeletion), aged 1.0-27.0 years were assessed for oral-motor, speech, language, literacy, and social functioning. Early history included hypotonia and feeding difficulties...

Purpose: Despite the widespread use of hand movements as visual and kinesthetic cues to facilitate accurate speech produced by individuals with speech sound disorders (SSDs), no experimental investigation of gestural cues that mimic that spatiotemporal parameters of speech sounds (e.g., holding fingers and thumb together and "popping" them to cue /p/) currently exists. The purpose of this study was to examine the effectiveness of manual mimicry cues within a multisensory intervention of persisting childhood apraxia of speech (CAS)...

We report the case of a 7-year-old male of Western European origin presenting with moderate intellectual disability, severe childhood apraxia of speech in the presence of oral and manual dyspraxia, and hypotonia across motor systems including the oral and speech motor systems. Exome sequencing revealed a de novo frameshift protein truncating mutation in the fourth exon of BCL11A, a gene recently demonstrated as being involved in cognition and language development. Making parallels with a previously described patient with a 200 kb 2p15p16...

The purpose of this study was to investigate the hypothesis that individuals with dyslexia and individuals with childhood apraxia of speech share an underlying persisting deficit in processing sequential information. Levels of impairment (sensory encoding, memory, retrieval, and motor planning/programming) were also investigated. Participants were 22 adults with dyslexia, 10 adults with a probable history of childhood apraxia of speech (phCAS), and 22 typical controls. All participants completed nonword repetition, multisyllabic real word repetition, and nonword decoding tasks...

In a companion study, adults with dyslexia and adults with a probable history of childhood apraxia of speech showed evidence of difficulty with processing sequential information during nonword repetition, multisyllabic real word repetition and nonword decoding. Results suggested that some errors arose in visual encoding during nonword reading, all levels of processing but especially short-term memory storage/retrieval during nonword repetition, and motor planning and programming during complex real word repetition...

Interstitial and terminal 6q25 deletions are associated with developmental delays, hypotonia, eye pathologies, craniofacial dysmorphologies, and structural brain anomalies. In most cases, speech and language deficits are not described in detail. We report on a case (Patient 1, age 7 years) with a de novo 6q25.3-qter deletion, 11.1 Mb long and encompassing 108 genes, and a case (Patient 2, age 5 years) with an inherited interstitial 6q25.3 deletion, located within Patient 1's deletion region and 403 kb long, the smallest 6q25 deletion reported to date...

The closely related paralogues FOXP2 and FOXP1 encode transcription factors with shared functions in the development of many tissues, including the brain. However, while mutations in FOXP2 lead to a speech/language disorder characterized by childhood apraxia of speech (CAS), the clinical profile of FOXP1 variants includes a broader neurodevelopmental phenotype with global developmental delay, intellectual disability, and speech/language impairment. Using clinical whole-exome sequencing, we report an identical de novo missense FOXP1 variant identified in three unrelated patients...

Purpose: The purpose of this study was to evaluate the role of practice variability, through prosodic variation during speech sound training, in biofeedback treatment for children with childhood apraxia of speech. It was hypothesized that variable practice would facilitate speech sound learning. Method: Six children ages 8-16 years with persisting speech sound errors due to childhood apraxia of speech participated in a single-subject experimental design. For each participant, 2 speech sound targets were treated with ultrasound visual feedback training: one with prosodic variation (i...
