Psychosocial Comorbidities in Adolescents With Histories of Childhood Apraxia of Speech.

Purpose Adolescent psychosocial outcomes of individuals with histories of childhood apraxia of speech (CAS) were compared to outcomes of individuals with histories of speech sound disorders (SSD) only and SSD with language impairment (LI). It was hypothesized that individuals with more severe and persistent disorders such as CAS would report poorer psychosocial outcomes. Method Groups were compared using analyses of variance on a psychosocial assessment battery that included measures of hyperactivity and inattention, anxiety, depression, internalizing and externalizing behaviors, thought problems, and social outcomes.

Association between genes regulating neural pathways for quantitative traits of speech and language disorders.

Speech sound disorders (SSD) manifest as difficulties in phonological memory and awareness, oral motor function, language, vocabulary, reading, and spelling. Families enriched for SSD are rare, and typically display a cluster of deficits. We conducted a genome-wide association study (GWAS) in 435 children from 148 families in the Cleveland Family Speech and Reading study (CFSRS), examining 16 variables representing 6 domains.

Feature-driven classification reveals potential comorbid subtypes within childhood apraxia of speech.

Background: Childhood apraxia of speech (CAS) is a neurodevelopmental disorder with heterogeneous communication and other comorbid manifestations. While previous studies have characterized speech deficits associated with CAS, few studies have examined variability in reading and language and/or other developmental comorbidities. We sought to identify comorbid subgroups within CAS that could be clinically relevant as well as genetically distinctive.

Differential Long-Term Outcomes for Individuals With Histories of Preschool Speech Sound Disorders.

Purpose The goal of this study was to determine whether adolescent outcomes for individuals with histories of early speech sound disorders (SSD) could be differentiated by speech and language skills at earlier ages (preschool, 4-6 years, and school age, 7-10 years). Method The study used a retrospective longitudinal design. Participants with and without histories of early SSD were classified in adolescence as having no SSD, resolved SSD, low multisyllabic word (MSW; difficulty with MSW repetition but no errors in conversational speech), or persistent speech disorders (errors in both conversational speech and MSW repetition).

Reading Outcomes for Individuals With Histories of Suspected Childhood Apraxia of Speech.

Purpose The primary aims of this study were to examine the speech-language correlates of decoding difficulties in children with histories of suspected childhood apraxia of speech (sCAS) and to identify predictors of low-proficiency reading levels. Method Participants were school-age children and adolescents, 7-18 years of age, diagnosed with sCAS ( = 40) or speech sound disorder but no sCAS (SSD-no sCAS; = 119). The sCAS and SSD-no sCAS reading groups were compared on measures of performance IQ, oral language, phonological awareness, rapid automatic naming, diadochokinetic rates, single word articulation, and multisyllable and nonsense word repetition.

Heritability and longitudinal outcomes of spelling skills in individuals with histories of early speech and language disorders.

This study examined the spelling skills in middle childhood and adolescence in individuals with histories of early childhood speech sound disorders (SSD) with and without language impairment (LI). Youth without such histories were also included (No SSD/LI group). The heritability of spelling skills at each age level was estimated.

Psychosocial co-morbidities in adolescents and adults with histories of communication disorders.

Background: Few studies have considered the long-term psychosocial outcomes of individuals with histories of early childhood speech sound disorders (SSD). Research on long-term psychosocial outcomes of individuals with language impairment (LI) have frequently failed to consider the effects of co-morbid SSD. The purpose of this study was to compare individuals with histories of SSD-only versus SSD with LI on these outcomes and to examine the contributions of other comorbid conditions including reading disorders (RD) and Attention Deficit Hyperactivity Disorder (ADHD).

Adolescent outcomes of children with early speech sound disorders with and without language impairment.

Purpose: In this study, the authors determined adolescent speech, language, and literacy outcomes of individuals with histories of early childhood speech sound disorders (SSD) with and without comorbid language impairment (LI) and examined factors associated with these outcomes.

Method: This study used a prospective longitudinal design. Participants with SSD (n = 170), enrolled at early childhood (4-6 years) were followed at adolescence (11-18 years) and were compared to individuals with no histories of speech or language impairment (no SSD; n = 146) on measures of speech, language, and literacy.

Association between AVPR1A, DRD2, and ASPM and endophenotypes of communication disorders.

Objectives: Speech sound disorder (SSD) is one of the most common communication disorders, with a prevalence rate of 16% at 3 years of age, and an estimated 3.8% of children still presenting speech difficulties at 6 years of age. Several studies have identified promising associations between communication disorders and genes in brain and neuronal pathways; however, there have been few studies focusing on SSD and its associated endophenotypes.

Reading skills of students with speech sound disorders at three stages of literacy development.

Purpose: The relationship between phonological awareness, overall language, vocabulary, and nonlinguistic cognitive skills to decoding and reading comprehension was examined for students at 3 stages of literacy development (i.e., early elementary school, middle school, and high school).

Speech-Sound Disorders and Attention-Deficit/Hyperactivity Disorder Symptoms.

Purpose: The purpose of this study was to examine the association of speech-sound disorders (SSD) with symptoms of attention-deficit/hyperactivity disorder (ADHD) by the severity of the SSD and the mode of transmission of SSD within the pedigrees of children with SSD.

Participants And Methods: The participants were 412 children who were enrolled in a longitudinal family study of SSD. Children were grouped on the basis of the severity of their SSD as determined by their scores on the Goldman-Fristoe Test of Articulation and history of an SSD.
