Agrammatic aphasia can be observed in neurodegenerative disorders and has been traditionally linked with damage to Broca's area, although there have been disagreements concerning whether damage to Broca's area is necessary or sufficient for the development of agrammatism. We aimed to investigate the neuroanatomical correlates of the emergence of agrammatic aphasia utilizing a unique cohort of patients with primary progressive apraxia of speech (PPAOS) that did not have agrammatism at baseline but developed agrammatic aphasia over time...

Purpose: Articulatory control and speech production accuracy were examined in children with childhood apraxia of speech (CAS) and typically developing (TD) controls within a novel word-learning task to better understand the influence of planning and programming deficits in the production of unfamiliar words. Method: Participants included 16 children between the ages of 5 and 6 years (8 CAS, 8 TD). Short- and long-term changes in lip and jaw movement, consonant and vowel accuracy, and token-to-token consistency were measured for 2 novel words that differed in articulatory complexity...

OBJECTIVE: This study describes the phenotype in a large family with a strong, multigenerational history of severe speech sound disorder (SSD) persisting into adolescence and adulthood in approximately half the cases. Aims were to determine whether a core phenotype, broader than speech, separated persistent from resolved SSD cases; and to ascertain the uniqueness of the phenotype relative to published cases. METHOD: Eleven members of the PM family (9-55 years) were assessed across cognitive, language, literacy, speech, phonological processing, numeracy, and motor domains...

Two patients with chronic Broca's aphasia participated in an oral reading treatment program. A multiple baseline design across responses was used. Materials consisted of 90 sentences randomly divided into three groups. Baseline performance was established; then each group of sentences was trained sequentially for 10 sessions. At the end of each session, oral reading performance was probed. For both patients, results indicated increases in accuracy of oral reading of treated materials, with maintenance of performance following termination of treatment...

Ultrasound imaging is an adjunct to traditional speech therapy that has shown to be beneficial in the remediation of speech sound errors. Ultrasound biofeedback can be utilized during therapy to provide clients with additional knowledge about their tongue shapes when attempting to produce sounds that are erroneous. The additional feedback may assist children with childhood apraxia of speech (CAS) in stabilizing motor patterns, thereby facilitating more consistent and accurate productions of sounds and syllables...

Apraxia of speech (AOS) is a motor speech disorder, most typically caused by stroke, which in its "pure" form (without other speech-language deficits) is very rare in clinical practice. Because some observable characteristics of AOS overlap with more common verbal communication neurologic syndromes (i.e. aphasia, dysarthria) distinguishing them may be difficult. The present study describes AOS in a 49-year-old right-handed male after left-hemispheric stroke. Analysis of his articulatory and prosodic abnormalities in the context of intact communicative abilities as well as description of symptoms dynamics over time provides valuable information for clinical diagnosis of this specific disorder and prognosis for its recovery...

Foreign accent syndrome (FAS) is a speech disorder that is defined by the emergence of a peculiar manner of articulation and intonation which is perceived as foreign. In most cases of acquired FAS (AFAS) the new accent is secondary to small focal lesions involving components of the bilaterally distributed neural network for speech production. In the past few years FAS has also been described in different psychiatric conditions (conversion disorder, bipolar disorder, and schizophrenia) as well as in developmental disorders (specific language impairment, apraxia of speech)...

Childhood apraxia of speech is a neurologic speech sound disorder in which children have difficulty constructing words and sounds due to poor motor planning and coordination of the articulators required for speech sound production. We report the case of a 3-year-old boy strongly suspected to have childhood apraxia of speech at 18 months of age who used multimodal communication to facilitate language development throughout his work with a speech language pathologist. In 18 months of an intensive structured program, he exhibited atypical rapid improvement, progressing from having no intelligible speech to achieving age-appropriate articulation...

The site of crucial damage that causes acquired apraxia of speech (AOS) has been debated in the literature. This study presents five in-depth cases that offer insight into the role of brain areas involved in AOS. Four of the examined participants had a primary impairment of AOS either with (n = 2) or without concomitant mild aphasia (n = 2). The fifth participant presented with a lesion relatively isolated to the left anterior insula (AIns-L), damage that is rarely reported in the literature, but without AOS...

INTRODUCTION: Existing literature suggests that the presence or absence of apraxia and associated parietal deficits may be clinically relevant in differential diagnosis of dementia syndromes. AIM: This study investigated the profile of these features in Alzheimer's disease (AD) and frontotemporal dementia (FTD) spectrum disorders, at first presentation. METHODS: Retrospective case note analysis was undertaken in 111 patients who presented to the Oxford Cognitive Disorders Clinic, Oxford, UK, including 29 amnestic AD, 12 posterior cortical atrophy (PCA), 12 logopenic primary progressive aphasia (lvPPA), 20 behavioural variant FTD (bvFTD), 7 non-fluent variant PPA (nfvPPA), 6 semantic variant PPA (svPPA) and 25 patients with subjective cognitive impairment (SCI)...

PURPOSE: The purpose of this study was to investigate current knowledge of the diagnosis childhood apraxia of speech (CAS) in Sweden and compare speech characteristics and symptoms to those of earlier survey findings in mainly English-speakers. METHOD: In a web-based questionnaire 178 Swedish speech-language pathologists (SLPs) anonymously answered questions about their perception of typical speech characteristics for CAS. They graded own assessment skills and estimated clinical occurrence...

BACKGROUND: Rapid Syllable Transitions (ReST) treatment uses pseudo-word targets with varying lexical stress to target simultaneously articulation, prosodic accuracy and coarticulatory transitions in childhood apraxia of speech (CAS). The treatment is efficacious for the acquisition of imitated pseudo-words, and generalization of skill to untreated pseudo-words and real words. Despite the growing popularity of telehealth as a method of service delivery, there is no research into the efficacy of telehealth treatments for CAS...

Childhood apraxia of speech (CAS) is a severe and socially debilitating form of speech sound disorder with suspected genetic involvement, but the genetic etiology is not yet well understood. Very few known or putative causal genes have been identified to date, e.g., FOXP2 and BCL11A. Building a knowledge base of the genetic etiology of CAS will make it possible to identify infants at genetic risk and motivate the development of effective very early intervention programs. We investigated the genetic etiology of CAS in two large multigenerational families with familial CAS...

Apraxia of speech (AOS) can be the presenting symptom of neurodegenerative disease. The position of primary progressive AOS in the nosology of the dementias is still controversial. Despite seeing many specialists, patients are often misdiagnosed, in part due to a lack of quantitative measures of speech dysfunction. We present a single case report of a patient presenting with AOS, including acoustic analysis, language assessment, and brain imaging. A 52-year-old woman presenting with AOS had remained undiagnosed for 6 years despite seeing 8 specialists...

PURPOSE: Treatment intensity (sometimes referred to as "practice amount") has been well-investigated in learning non-speech tasks, but its role in treating speech disorders has not been largely analysed. This study reviewed the literature regarding treatment intensity in speech disorders. METHOD: A systematic search was conducted in four databases using appropriate search terms. Seven articles from a total of 580 met the inclusion criteria. The speech disorders investigated included speech sound disorders, dysarthria, acquired apraxia of speech and childhood apraxia of speech...

PURPOSE: Motor speech characteristics of children with Down syndrome (DS) have historically been viewed as either Childhood Dysarthria (CD) or, more infrequently, as Childhood Apraxia of Speech (CAS). The objective of this study was to investigate motor speech deficits in a systematic manner, considering characteristics from both CAS and CD. METHOD: Motor speech assessments were carried out on seven 3;4-8;11-year old children with DS in comparison with younger, typically-developing children using a Language-Neutral Assessment of Motor Speech for young children (LAMS)...

PURPOSE: This study was designed to examine the effects of practice schedule, blocked vs random, on outcomes of a behavioural treatment for acquired apraxia of speech (AOS), Sound Production Treatment (SPT). METHOD: SPT was administered to four speakers with chronic AOS and aphasia in the context of multiple baseline designs across behaviours and participants. Treatment was applied to multiple sound errors within three-to-five syllable words. All participants received both practice schedules: SPT-Random (SPT-R) and SPT-Blocked (SPT-B)...

This paper presents the case of a 17-year-old right-handed Belgian boy with developmental FAS and comorbid developmental apraxia of speech (DAS). Extensive neuropsychological and neurolinguistic investigations demonstrated a normal IQ but impaired planning (visuo-constructional dyspraxia). A Tc-99m-ECD SPECT revealed a significant hypoperfusion in the prefrontal and medial frontal regions, as well as in the lateral temporal regions. Hypoperfusion in the right cerebellum almost reached significance. It is hypothesized that these clinical findings support the view that FAS and DAS are related phenomena following impairment of the cerebro-cerebellar network...

Beta-amyloid (Aβ) deposition can be observed in primary progressive aphasia (PPA) and progressive apraxia of speech (PAOS). While it is typically associated with logopenic PPA, there are exceptions that make predicting Aβ status challenging based on clinical diagnosis alone. We aimed to determine whether MRI regional volumes or clinical data could help predict Aβ deposition. One hundred and thirty-nine PPA (n = 97; 15 agrammatic, 53 logopenic, 13 semantic and 16 unclassified) and PAOS (n = 42) subjects were prospectively recruited into a cross-sectional study and underwent speech/language assessments, 3...
