Association of congenital heart disease and neurodevelopmental disorders: an observational and Mendelian randomization study.

BACKGROUND: This study aims to thoroughly study the connection between congenital heart disease (CHD) and neurodevelopmental disorders (NDDs) through observational and Mendelian randomization (MR) designs. METHODS: This observational study uses data from the National Survey of Children's Health (2020-2021). Multivariable logistic regression and propensity score matching (PSM) were performed to analyze the association. PSM was used to minimize bias for covariates such as age, race, gender, maternal age, birth weight, concussion or brain injury, preterm birth, cerebral palsy, Down syndrome, and other inherited conditions. In MR analyses, inverse variance-weighted measures, weighted median, and MR-Egger were employed to calculate causal effects. RESULTS: A total of 85,314 children aged 0-17 were analyzed in this study. In regression analysis, CHD (p = 0.04), the current heart condition (p = 0.03), and the severity of current heart condition (p < 0.05) had a suggestive association with speech or language disorders. The severity of current heart condition (p = 0.08) has a potential statistically significant association with attention deficit hyperactivity disorder(ADHD). In PSM samples, ADHD(p = 0.003), intellectual disability(p = 0.012), and speech or language disorders(p < 0.001) were all significantly associated with CHD. The severity of current heart condition (p < 0.001) also had a significant association with autism. MR analysis did not find causality between genetically proxied congenital cardiac malformations and the risk of NDDs. CONCLUSIONS: Our study shows that children with CHD have an increased risk of developing NDDs. Heart conditions currently and severity of current heart conditions were also significantly associated with these NDDs. In the future, we need to try more methods to clarify the causal relationship between CHD and NDDs.

Donna Jackson-Maldonado. A life dedicated to joining theory and practice in language development research / Donna Jackson-Maldonado. Una vida dedicada a unir teoría y práctica en la investigación del desarrollo del lenguaje

Precedents and objectives: Dr Donna Jackson-Maldonado, researcher and professor at the Centro de Estudios Lingüísticos y Literarios of the Universidad Autónoma de Querétaro in Mexico, left us on November 30, 2021. In this article, we review her main scientific contributions related to the three fundamental axes on which she worked: language acquisition, language disorders and language assessment. Methods and results: Dr Jackson-Maldonado's studies on language acquisition included groups of premature babies, late talkers, and typical development children in bilingual and diverse socioeconomic conditions. Moreover, she studied atypical language development in children with hearing loss, children with developmental language disorders and children with Down syndrome and other syndromes. Finally, regarding language assessment, it should be noted that she led the Mexican Spanish version of the Communicative Development Inventories (CDI) that was used as a model for later adaptations in other Romance languages. Discussion and conclusion: Dr Jackson-Maldonado's methodological approach combined rigour with a creative and innovative scientific spirit, yet she integrated theory and clinical practice from its very beginning. She left us an immense research and personal legacy that we want to honour in this paper.

El desarrollo atípico del lenguaje en niños con discapacidad auditiva. ¿Posible tdl? / Atypical language development in children with hearing disabilities. Possible tdl?

Introducción: El avance de la ciencia ha permitido que los niños con discapacidad auditiva (DA) dispongan de ayudas necesarias y desarrollen una competencia comunicativo-lingüística acorde a su edad cronológica, pero existe un determinado porcentaje de estos niños con un desarrollo atípico del lenguaje. Objetivos: La finalidad de este trabajo es comprobar si el desarrollo atípico del lenguaje de niños con DA es o no una consecuencia de dicha pérdida de audición. Para ello, se evaluó en dos ocasiones el lenguaje de 12 niños con DA y, de ellos, 3 casos obtuvieron unos resultados lingüísticos que no correspondían a lo esperado por su edad cronológica, por lo que se pretende comprobar si son susceptibles de tener un déficit lingüístico no asociado al auditivo. Metodología: Se sigue una metodología mixta, se analiza de forma cualitativa y cuantitativa los resultados de diversas pruebas del lenguaje aplicadas en la reevaluación: PLON-R, BLOC-SR, PEABODY y Evaluación fonológica del habla Infantil. Los resultados se comparan con los obtenidos en la evaluación anterior y en otros estudios. Se contrastan hipótesis formuladas anteriormente discutiendo la posibilidad de un diagnóstico doble de discapacidad auditiva y un Trastorno del Desarrollo del Lenguaje (TDL). Resultados: El análisis de los resultados refleja que las puntuaciones obtenidas en la primera evaluación corresponden a las de la segunda; las puntuaciones siguen siendo bajas, evidenciándose dificultades en la morfosintaxis y en el desarrollo y uso del repertorio fonológico. Discusión y conclusiones: El porcentaje de niños con DA que no alcanzan una competencia comunicativo-lingüística acorde a su edad puede alcanzar el 30%. Los tres casos analizados presentan trastorno fonológico-sintáctico y agnosia auditivo-verbal, características compatibles a las de varios tipos de TDL...(AU)

[Studies on the association of genes with language disorders in the post-genomic era].

Since genetic research entered the post-genomic era, the high heritability of language disorders has been confirmed. A variety of genetic-related diseases may cause various types of language disorders in children and/or adults. This article has summarized language disorders and their underlying mechanisms by searching the Web of Science database over the last decade, and combed the genetic researches for dyslexia, frontotemporal degeneration, specific language disorder, childhood speech apraxia and other single diseases that are strongly associated with the language disorders. It also provided a discussion over the co-occurrence of multiple diseases, with an aim to revealing the genetic association and/or pathogenetic mechanism in order to provide inspiration for the prevention, diagnosis, and treatment of language disorders.

Spoken verb learning in children with language disorder.

The current study examined spoken verb learning in elementary school children with language disorder (LD). We aimed to replicate verb learning deficits reported in younger children with LD and to examine whether verb instrumentality, a semantic factor reflecting whether an action requires an instrument (e.g., "to chop" is an instrumental verb), influenced verb learning. The possible facilitating effect of orthographic cues presented during training was also evaluated. In an exploratory analysis, we investigated whether language and reading skills mediated verb learning performance. General language skills and verb learning were assessed in Dutch children with LD and age-matched typically developing controls (n = 25 per group) aged 8 to 12 years (M = 9;9 [years;months], SD = 1;3). Using video animations, children learned 20 nonwords depicting actions comprising 10 instrumental and 10 noninstrumental verbs. Half of the items were trained with orthographic information present. Verb learning was assessed using an animation-word matching and animation naming task. Linear mixed-effects models showed a main effect of group for all verb learning measures, demonstrating that children with LD learned fewer words and at a slower rate than the control group. No effect of verb instrumentality, presence of orthographic information, or the included mediators was found. Our results emphasize the importance of continued vocabulary instruction in elementary school to strengthen verb encoding. Given that our findings are inconsistent with the overall literature showing an orthographic facilitation effect, future studies should investigate whether participants pay attention to the written word form in learning contexts with moving stimuli.

Neurodevelopmental outcomes after prenatal exposure to lamotrigine monotherapy in women with epilepsy: a systematic review and meta-analysis.

BACKGROUND: Lamotrigine has become one of the most commonly prescribed antiseizure medications (ASM) in epileptic women during pregnancy and therefore requires regular updates regarding its safety. The aim of this study was to estimate the association between in utero exposure to lamotrigine monotherapy and the occurrence of neurodevelopmental outcomes. METHODS: All comparative studies assessing the occurrence of neurodevelopmental outcomes after epilepsy-indicated lamotrigine monotherapy exposure during pregnancy were searched. First, references were identified through a snowballing approach, then, through electronic databases (Medline and Embase) from 2015 to June 2022. One investigator evaluated study eligibility and extracted data and a second independent investigator reviewed the meta-analysis (MA). A systematic review and random-effects model approach were performed using a collaborative WEB-based meta-analysis platform (metaPreg.org) with a registered protocol (osf.io/u4gva). RESULTS: Overall, 18 studies were included. For outcomes reported by at least 4 studies, the pooled odds ratios and 95% confidence interval obtained with the number of exposed (N1) and unexposed children (N0) included were: neurodevelopmental disorders as a whole 0.84 [0.66;1.06] (N1 = 5,271; N0 = 22,230); language disorders or delay 1.16 [0.67;2.00] (N1 = 313; N0 = 506); diagnosis or risk of ASD 0.97 [0.61;1.53] (N1 = at least 5,262; N0 = 33,313); diagnosis or risk of ADHD 1.14 [0.75;1.72] (N1 = at least 113; N0 = 11,530) and psychomotor developmental disorders or delay 2.68 [1.29-5.56] (N1 = 163; N0 = 220). The MA of cognitive outcomes included less than 4 studies and retrieved a significant association for infants exposed to lamotrigine younger than 3 years old but not in the older age groups. CONCLUSION: Prenatal exposure to lamotrigine monotherapy is not found to be statistically associated with neurodevelopmental disorders as a whole, language disorders or delay, diagnosis or risk of ASD and diagnosis or risk of ADHD. However, the MA found an increased risk of psychomotor developmental disorders or delay and cognitive developmental delay in less than 3 years old children. Nevertheless, these findings were based exclusively on observational studies presenting biases and on a limited number of included children. More studies should assess neurodevelopmental outcomes in children prenatally exposed to lamotrigine.

Verbal expressive language minimally affected in non-demented people living with amyotrophic lateral sclerosis.

Objective: Language dysfunction is one of the most common cognitive impairments in amyotrophic lateral sclerosis (ALS). Although discourse capacities are essential for daily functioning, verbal expressive language has not been widely investigated in ALS. The existing research available suggests that discourse impairments are prevalent. This study investigates verbal expressive language in people living with ALS (plwALS) in contrast to healthy controls (HC).Methods: 64 plwALS and 49 age, gender and education-matched healthy controls were ask to describe the Cookie Theft Picture Task. The recordings were analyzed for discourse productivity, discourse content, syntactic complexity, speech fluency and verb processing. We applied the Bayesian hypothesis-testing framework, incorporating the effects of dysarthria, cognitive impairment status (CIS), and premorbid crystalline verbal IQ.Results: Compared to HC, plwALS only showed a single impairment: speech dysfluency. Discourse productivity, discourse content, syntactic complexity and verb processing were not impaired. Cognition and dysarthria exceeded the influence of verbal IQ for total words spoken and content density. Cognition alone seemed to explain dysfluency. Body-agent verbs were produced at even higher rates than other verb types. For the remaining outcomes, verbal IQ was the most decisive factor.Conclusions: In contrast to existing research, our data demonstrates no discernible impairment in verbal expressive language in ALS. What our findings show to be decisive is accounting for the influence of dysarthria, cognitive impairment status, and verbal IQ as variables on spontaneous verbal expressive language. Minor impairments in verbal expressive language appear to be influenced to a greater degree by executive dysfunctioning and dysarthria than by language impairment.

Novel FOXP2 variant associated with speech and language dysfunction in a Chinese family and literature review.

Since its initial identification, the Forkhead Box P2 gene (FOXP2) has maintained its singular status as the archetypal monogenic determinant implicated in Mendelian forms of human speech and language impairments. Despite the passage of two decades subsequent to its discovery, extant literature remains disproportionately sparse with regard to case-specific instances and loci of mutational perturbations. The objective of the current investigation centers on furnishing an enriched delineation of both its clinical manifestations and its mutational heterogeneity. Clinical phenotypes and peripheral blood samples were assiduously amassed from familial subjects. Whole-exome sequencing and Sanger sequencing methodologies were deployed for the unambiguous identification of potential genetic variants and for corroborating their co-segregation within the family pedigree. An exhaustive review of published literature focusing on patients manifesting speech and language disorders consequent to FOXP2 genetic anomalies was also undertaken. The investigation yielded the identification of a novel heterozygous variant, c.661del (p.L221Ffs*41), localized within the FOXP2 gene in the proband, an inheritance from his symptomatic mother. The proband presented with an array of symptoms, encompassing dysarthric speech, deficits in instruction comprehension, and communicative impediments. In comparison, the mother exhibited attenuated symptoms, including rudimentary verbalization capabilities punctuated by pronounced stuttering and dysarthria. A comprehensive analysis of articles archived in the Human Gene Mutation Database (HGMD) classified under "DM" disclosed the existence of 74 patients inclusive of the subjects under current examination, sub-divided into 19 patients with null variants, 5 patients with missense variants, and 50 patients with gross deletions or complex genomic rearrangements. A conspicuous predominance of delayed speech, impoverished current verbal abilities, verbal comprehension deficits, and learning difficulties were observed in patients harboring null or missense FOXP2 variants, as compared to their counterparts with gross deletions or complex rearrangements. Developmental delays, hypotonia, and craniofacial aberrations were exclusive to the latter cohort. The elucidated findings augment the existing corpus of knowledge on the genetic architecture influencing both the proband and his mother within this specified familial context. Of critical importance, these discoveries furnish a robust molecular framework conducive to the prenatal diagnostic evaluations of prospective progeny within this familial lineage.

Vowel distinctiveness as a concurrent predictor of expressive language function in autistic children.

Speech ability may limit spoken language development in some minimally verbal autistic children. In this study, we aimed to determine whether an acoustic measure of speech production, vowel distinctiveness, is concurrently related to expressive language (EL) for autistic children. Syllables containing the vowels [i] and [a] were recorded remotely from 27 autistic children (4;1-7;11) with a range of spoken language abilities. Vowel distinctiveness was calculated using automatic formant tracking software. Robust hierarchical regressions were conducted with receptive language (RL) and vowel distinctiveness as predictors of EL. Hierarchical regressions were also conducted within a High EL and a Low EL subgroup. Vowel distinctiveness accounted for 29% of the variance in EL for the entire group, RL for 38%. For the Low EL group, only vowel distinctiveness was significant, accounting for 38% of variance in EL. Conversely, in the High EL group, only RL was significant and accounted for 26% of variance in EL. Replicating previous results, speech production and RL significantly predicted concurrent EL in autistic children, with speech production being the sole significant predictor for the Low EL group and RL the sole significant predictor for the High EL group. Further work is needed to determine whether vowel distinctiveness longitudinally, as well as concurrently, predicts EL. Findings have important implications for the early identification of language impairment and in developing language interventions for autistic children.

Story Grammar Analyses Capture Discourse Improvement in the First 2 Years Following a Severe Traumatic Brain Injury.

PURPOSE: Narration within a story grammar framework requires speakers to organize characters and events logically. Despite abundant research characterizing narrative deficits following a traumatic brain injury (TBI), the evolution of narrative story grammar over the first 2 years post-TBI has rarely been explored. This study analyzed story grammar in complex narratives of adults with and without severe TBI to (a) examine between-group differences and (b) investigate longitudinal changes over the first 2 years post-TBI. METHOD: Story grammar analyses of Cinderella narratives from 57 participants with TBI and 57 participants with no brain injury yielded measures of productivity (total number of episodes, total number of story grammar elements), elaboration (total number of elaborated-complete episodes, mean number of episodic elements per episode), and completeness (total number of incomplete episodes). Mann-Whitney U tests compared measures across groups; generalized estimating equation (GEE) models identified predictors of change, including recovery time (3, 6, 9, 12, and 24 months post-TBI) and demographic/injury-related characteristics. RESULTS: Between-group differences were statistically significant for all productivity and elaboration measures at 3, 6, and 9 months post-TBI; one productivity measure and one elaboration measure at 12 months; and none of the measures at 24 months. GEE models showed significant improvements in all productivity and elaboration measures over the first 24 months post-TBI, with educational attainment and duration of posttraumatic amnesia affecting recovery. Incomplete episodes only showed between-group differences at 12 months and did not capture recovery. CONCLUSION: Productivity and elaboration are key story grammar variables that (a) differentiate complex narration in individuals with and without severe TBI and (b) capture narrative improvements over the first 2 years post-TBI.

Exploring Speech-Language Pathologists' Perception of and Individualized Education Program Goals for Vocabulary Intervention With School-Age Children With Language Disorders.

PURPOSE: Among the varied roles and responsibilities of school-based speech-language pathologists (SLPs) are the planning and delivery of effective vocabulary intervention for students with language disorders. Despite the abundant literature regarding effective vocabulary intervention, practice patterns indicate that the research has not yet translated to practice. The purpose of this study was to examine SLPs' beliefs and expectations regarding vocabulary instruction and the content of Individualized Education Program (IEP) goals to better inform continuing education and research programs to generate lasting effects on SLP practices. METHOD: We queried a national sample of school-based SLPs via an online survey regarding their perspectives on robust vocabulary instruction, vocabulary intervention practices, and IEP goal development targeting vocabulary skills for school-age children with language disorders. RESULTS: There was consistency across the sample for SLPs' beliefs about the importance and impact of robust vocabulary instruction. However, they reflected varied expectations about the vocabulary intervention they provide. Qualitative analysis of IEP goals for vocabulary reveals the range and frequency of strategies and intervention targets as an artifact of implementation of robust vocabulary instruction. CONCLUSIONS: School-based SLPs believe that vocabulary is important and have a strong understanding of the impact robust vocabulary instruction can have on reading and writing outcomes. SLPs in this sample had varying expectations regarding the way their instruction is implemented and generalized. Implications and limitations of these results are discussed.

Navigating the semantic space: Unraveling the structure of meaning in psychosis using different computational language models.

Speech in psychosis has long been ascribed as involving 'loosening of associations'. We pursued the aim to elucidate its underlying cognitive mechanisms by analysing picture descriptions from 94 subjects (29 healthy controls, 18 participants at clinical high risk, 29 with first-episode psychosis, and 18 with chronic schizophrenia), using five language models with different computational architectures: FastText, which represents meaning non-contextually/statically; BERT, which represents contextual meaning sensitive to grammar and context; Infersent and SBERT, which provide sentential representations; and CLIP, which evaluates speech relative to a visual stimulus. These models were used to quantify semantic distances crossed between successive tokens/sentences, and semantic perplexity indicating unexpectedness in continuations. Results showed that, among patients, semantic similarity increased when measured with FastText, Infersent, and SBERT, while it decreased with CLIP and BERT. Higher perplexity was observed in first-episode psychosis. Static semantic measures were associated with clinically measured impoverishment of thought and referential semantic measures with disorganization. These patterns indicate a shrinking conceptual semantic space as represented by static language models, which co-occurs with a widening in the referential semantic space as represented by contextual models. This duality underlines the need to separate these two forms of meaning for understanding mechanisms involved in semantic change in psychosis.

Validity and Reliability Study of the Turkish Version of Focus on the Outcomes of Communication Under Six-34.

PURPOSE: Speech and language disorders can negatively affect preschool children's communicative participation skills. Focus on the Outcomes of Communication Under Six-34 (FOCUS-34) is a valid and reliable scale that evaluates communicative participation in preschool children with speech and language disorders. This study aimed to establish the Turkish version of FOCUS-34 (FOCUS-34-TR) and investigate its validity and reliability. METHOD: A total of 175 children with language disorders, speech sound disorders, and fluency disorders (aged 20-72 months) and their parents were included in the study. Parents were asked to complete the demographic information form, the FOCUS-34-TR scale, and the Ages and Stages Questionnaires: Social-Emotional (ASQ-SE) Turkish version. The construct validity, convergent and divergent validity, internal consistency, and test-retest reliability of the scale were investigated. RESULTS: The FOCUS-34-TR had high values for internal consistency (α = .97) and test-retest reliability (r = .95). The correlations between the FOCUS-34-TR total score and its subscales were between .77 and .90. A moderately significant negative correlation was found between the FOCUS-34-TR scale and the ASQ-SE. CONCLUSION: The Turkish version of FOCUS-34 is a valid and reliable scale that can be used in clinics and for research purposes to evaluate the communicative participation skills of Turkish-speaking preschool children with speech and language disorders.

Characterising the social interaction style of autism in young adult males with fragile X syndrome.

BACKGROUND: The characterisation of autism in fragile X syndrome (FXS) has been a source of controversy due to the complexity of disentangling autism traits from common features of the FXS phenotype. Autism in FXS is significantly underdiagnosed in the community, which may be partly due to insufficient clinical description of the social interaction profile of autism within the FXS phenotype. In this study, we applied a classic framework for characterising social interaction styles in autism to a sample of young adult males with FXS and co-occurring autism to enhance understanding of how the social challenges associated with autism manifest within FXS. METHODS: Participants were 41 males (M age = 18 years) with FXS and co-occurring autism. Interaction samples were coded for expression of predominately 'active' (characterised by a desire to make social approaches) or 'passive' (characterised by lack of initiation of social approach towards others) interaction profiles. Differences in the expression of phenotypic features of FXS, including anxiety, attention-deficit/hyperactivity disorder, cognitive, adaptive and language impairments and autism symptom severity, were examined across those with passive and active interaction styles. RESULTS: Approximately half of the sample was classified as active and half as passive, demonstrating diversity in the social phenotype of autism associated with FXS. The two subtypes did not differ in autism severity, anxiety or attention-deficit/hyperactivity disorder symptoms or in cognitive, adaptive or language abilities. CONCLUSIONS: This study enhances understanding of FXS-associated autism by documenting phenotypic variability in the social interaction profile in this group, with active and passive social interaction styles represented. The two social interaction styles were not associated with differential expression of common phenotypic features of FXS, suggesting similar support needs.

Impulsive and compulsive reading comprehension in the prison population.

BACKGROUND: Developmental dyslexia is characterized by reading and writing deficits that persist into adulthood. Dyslexia is strongly associated with academic underachievement, as well as impulsive, compulsive, and criminal behaviors. The aims of this study were to investigate impulsive or compulsive reading comprehension, analyzing the differences in reading errors between two distinct groups -one with Antisocial Personality Disorder (ASPD) and another with Obsessive-Compulsive Personality Disorder (OCPD) and examine their correlation with criminal behavior within a prison population. METHODS: We gathered data from 194 participants: 81 with ASPD and 113 with OCPD from a prison center. Participants took part in interviews to gather data on demographic, criminal, and behavioral data. Additionally, the participants underwent various assessments, including the International Examination for Personality Disorders; Symptom Inventory, and Battery for the Assessment of Reading Processes in Secondary and High School - Revised. RESULTS: Our analysis revealed differences in reading skills between the ASPD and OCPD groups. Specifically, the OCPD group showed poorer performance on lexical selection, semantic categorization, grammar structures, grammatical judgements, and expository comprehension when compared with the ASPD group. Conversely, the OCPD group obtained higher scores on narrative comprehension relative to the ASPD group. CONCLUSIONS: The OCPD group showed slow lexical-phonological coding and phonological activation.

Gestational diabetes mellitus and risk of neurodevelopmental disorders in young offspring: does the risk differ by race and ethnicity?

BACKGROUND: Previous studies examined the associations of gestational diabetes mellitus with autism spectrum disorder and attention deficit hyperactivity disorder. However, the associations between gestational diabetes mellitus and other neurodevelopmental disorders, such as the common speech/language disorder and developmental coordination disorder, are rarely studied, and whether the associations vary by race/ethnicity remains unknown. OBJECTIVE: This study aimed to examine the associations of gestational diabetes mellitus with individual neurodevelopmental disorders in young offspring, and to investigate whether the associations vary by race/ethnicity. STUDY DESIGN: This retrospective cohort study (Glucose in Relation to Women and Babies' Health [GrownB]) included 14,480 mother-offspring pairs in a large medical center in the United States from March 1, 2013 to August 31, 2021. We ascertained gestational diabetes mellitus using the validated ICD (International Classification of Diseases) codes (ICD-9: 648.8x; ICD-10: O24.4x), and identified neurodevelopmental disorders (speech/language disorder, developmental coordination disorder, autism spectrum disorder, and other neurodevelopmental disorders [attention deficit hyperactivity disorder, behavioral disorder, intellectual disability, and learning difficulty]) and their combinations using validated algorithms. We compared the hazard of neurodevelopmental disorders during the entire follow-up period between offspring born to mothers with and without gestational diabetes mellitus using multivariable Cox regression models. RESULTS: Among all mothers, 19.9% were Asian, 21.8% were Hispanic, 41.0% were non-Hispanic White, and 17.3% were of other/unknown race/ethnicity. During the median follow-up of 3.5 years (range, 1.0-6.3 years) after birth, 8.7% of offspring developed at least 1 neurodevelopmental disorder. Gestational diabetes mellitus was associated with a higher risk of speech/language disorder (adjusted hazard ratio, 1.59 [95% confidence interval, 1.07-2.35]), developmental coordination disorder (2.36 [1.37-4.04]), autism spectrum disorder (3.16 [1.36-7.37]), other neurodevelopmental disorders (3.12 [1.51-6.47]), any neurodevelopmental disorder (1.86 [1.36-2.53]), the combination of speech/language disorder and autism spectrum disorder (3.79 [1.35-10.61]), and the combination of speech/language disorder and developmental coordination disorder (4.22 [1.69-10.51]) among offspring born to non-Hispanic White mothers. No associations between gestational diabetes mellitus and any neurodevelopmental disorders or their combinations were observed among offspring born to mothers of other racial/ethnic groups. CONCLUSION: We observed an elevated risk of neurodevelopmental disorders among young offspring born to non-Hispanic White mothers with gestational diabetes mellitus, but not among other racial/ethnic groups.

A scoping review of oral language and social communication abilities in children with Tourette syndrome.

BACKGROUND: Children with Tourette syndrome (TS) have historically experienced problems in academic and social settings, yet their language and communication abilities have not been extensively researched. AIMS: This scoping review maps the literature on the oral language and social communication abilities of children with TS in order to describe the nature of the current literature, present a summary of major findings and identify where gaps exist. METHODS: A scoping review was completed to identify studies measuring the oral language or social communication abilities of children with TS. A systematic search of six electronic databases was conducted to obtain published and unpublished literature. All English studies measuring the oral language or social communication abilities of children with TS were included. Information was extracted from records and knowledge was synthesised in a narrative summary. MAIN CONTRIBUTION: We identified 56 records for inclusion. Almost all records were located in journals within the fields of psychology and psychiatry. Skills most often studied were verbal IQ and verbal fluency. The literature suggests an increased prevalence of language disorders and social communication problems in children with TS; however, literature comprehensively detailing these challenges was scarce. Language strengths were identified in verbal intelligence, story/sentence recall, categorisation and performance on tasks at the single-word level. CONCLUSIONS: Oral language and social communication skills are important for academic and social success. This review brings scattered literature together to provide up-to-date information about language in children with TS and highlights that there are considerable gaps in our knowledge about language and communication in this population. This scoping review can inform future research and support speech language pathologists in the assessment of young people with TS. WHAT THIS PAPER ADDS: What is already known on the subject Speech-language pathologists (SLPs) working in various contexts (e.g., schools, mental health teams) are likely to encounter children with Tourette syndrome (TS); however, the description of this population and potential communication characteristics is not well represented in the SLP literature. Previous literature reviews have reported strengths in verbal fluency and morphological processing. Challenges in expressive language, higher order language, social cognition and a propensity towards autistic traits have also been identified. What this paper adds to existing knowledge This review differs from previous narrative reviews by employing a systematic approach to searching for literature. As a result, we identified 25 additional studies that had not been cited in previous reviews and additional relevant findings in 23 previously reviewed studies. This review confirms several previous conclusions about language in children with TS and extends or clarifies several others, thereby providing the most current information on oral language and social communication abilities. The use of current taxonomies of language and social communication helps to organise this literature for clinicians and researchers in speech-language pathology and identifies a need for further research from the SLP perspective. What are the potential or actual clinical implications of this work? These results imply that SLPs should screen children with TS for language disorders and investigate social communication and social interaction development. Clinicians can expect greater challenges in language and communication development for children with complex forms of TS (i.e., those who exhibit co-occurring conditions such as attention-deficit/hyperactivity disorder). The multidisciplinary nature of the current literature implies that clinical collaboration with other disciplines will be of particular benefit to serving this group of children.

Methodologies for assessing morphosyntactic ability in people with Alzheimer's disease.

BACKGROUND: The detection and description of language impairments in neurodegenerative diseases like Alzheimer's Disease (AD) play an important role in research, clinical diagnosis and intervention. Various methodological protocols have been implemented for the assessment of morphosyntactic abilities in AD; narrative discourse elicitation tasks and structured experimental tasks for production, offline and online structured experimental tasks for comprehension. Very few studies implement and compare different methodological protocols; thus, little is known about the advantages and disadvantages of each methodology. AIMS: To discuss and compare the main behavioral methodological approaches and tasks that have been used in psycholinguistic research to assess different aspects of morphosyntactic production and comprehension in individuals with AD at the word and sentence levels. METHODS: A narrative review was conducted through searches in the scientific databases Google Scholar, Scopus, Science Direct, MITCogNet, PubMed. Only studies written in English, that reported quantitative data and were published in peer-reviewed journals were considered with respect to their methodological protocol. Moreover, we considered studies that reported research on all stages of the disease and we included only studies that also reported results of a healthy control group. Studies that implemented standardized assessment tools were not considered in this review. OUTCOMES & RESULTS: The main narrative discourse elicitation tasks implemented for the assessment of morphosyntactic production include interviews, picture-description and story narration, whereas the main structured experimental tasks include sentence completion, constrained sentence production, sentence repetition and naming. Morphosyntactic comprehension in AD has been assessed with the use of structured experimental tasks, both offline (sentence-picture matching, grammaticality judgment) and online (cross-modal naming,speeded sentence acceptability judgment, auditory moving window, word detection, reading). For each task we considered studies that reported results from different morphosyntactic structures and phenomena in as many different languages as possible. CONCLUSIONS & IMPLICATIONS: Our review revealed strengths and weaknesses of these methods but also directions for future research. Narrative discourse elicitation tasks as well as structured experimental tasks have been used in a variety of languages, and have uncovered preserved morphosyntactic production but also deficits in people with AD. A combination of narrative discourse elicitation and structured production tasks for the assessment of the same morphosyntactic structure has been rarely used. Regarding comprehension, offline tasks have been implemented in various languages, whereas online tasks have been mainly used in English. Offline and online experimental paradigms have often produced contradictory results even within the same study. The discrepancy between the two paradigms has been attributed to the different working memory demands they impose to the comprehender or to the different parsing processes they tap. Strengths and shortcomings of each methodology are summarized in the paper, and comparisons between different tasks are attempted when this is possible. Thus, the paper may serve as a methodological guide for the study of morphosyntax in AD and possibly in other neurodegenerative diseases. WHAT THIS PAPER ADDS: What is already known on this subject For the assessment of morphosyntactic abilities in AD, various methodological paradigms have been implemented: narrative discourse elicitation tasks and structured experimental tasks for production, and offline and online structured experimental tasks for comprehension. Very few studies implement and compare different methodological protocols; thus, little is known about the advantages and disadvantages of each methodology. What this paper adds to existing knowledge The paper presents an overview of methodologies that have been used to assess morphosyntactic production and comprehension of people with AD at the word and sentence levels. The paper summarizes the strengths and shortcomings of each methodology, providing both the researcher and the clinician with some directions in their endeavour of investigating language in AD. Also, the paper highlights the need for further research that will implement carefully scrutinized tasks from various experimental paradigms and will explore distinct aspects of the AD patients' morphosyntactic abilities in typologically different languages. What are the potential or actual clinical implications of this work? The paper may serve as a reference point for (psycho-)linguists who wish to study morphosyntactic abilities in AD, and for speech and language therapists who might need to apply morphosyntactic protocols to their patients in order to assess them or design appropriate therapeutic interventions for production and comprehension deficits.
