Esposito D, Cruciani G, Zaccaro L, Di Carlo E, Spitoni GF, Manti F, Carducci C, Fiori E, Leuzzi V, Pascucci T. A Systematic Review on Autism and Hyperserotonemia: State-of-the-Art, Limitations, and Future Directions. Brain Sci 2024; 14:481. [PMID: 38790459 PMCID: PMC11119126 DOI: 10.3390/brainsci14050481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Revised: 04/29/2024] [Accepted: 05/02/2024] [Indexed: 05/26/2024] Open
Abstract
Hyperserotonemia is one of the most studied endophenotypes in autism spectrum disorder (ASD), but there are still no unequivocal results about its causes or biological and behavioral outcomes. This systematic review summarizes the studies investigating the relationship between blood serotonin (5-HT) levels and ASD, comparing diagnostic tools, analytical methods, and clinical outcomes. A literature search on peripheral 5-HT levels and ASD was conducted. In total, 1104 publications were screened, of which 113 entered the present systematic review. Of these, 59 articles reported hyperserotonemia in subjects with ASD, and 26 presented correlations between 5-HT levels and ASD-core clinical outcomes. The 5-HT levels are increased in about half, and correlations between hyperserotonemia and clinical outcomes are detected in a quarter of the studies. The present research highlights a large amount of heterogeneity in this field, ranging from the characterization of ASD and control groups to diagnostic and clinical assessments, from blood sampling procedures to analytical methods, allowing us to delineate critical topics for future studies.

Abstract
IMPORTANCE Static picture (SP) schedules are an established intervention for children with autism spectrum disorder (ASD), but the use of video modeling (VM) has not been thoroughly investigated. OBJECTIVE To compare the effectiveness of VM prompts versus SP prompts in improving autistic children's independence with daily living skills. DESIGN An experimental alternating treatment design. SETTING Approved private school for children with disabilities. PARTICIPANTS Seventeen participants (13 male and 4 female; ages 9-18 yr) with an ASD diagnosis. INTERVENTION Visual prompts using a tablet were provided during task participation, with data collected in two phases. OUTCOMES AND MEASURES Type and frequency of the prompts required to complete the task were documented for each participant during the intervention session. RESULTS Both VM and SP conditions resulted in improvements in at least one phase. Most participants demonstrated a decrease in the number of required cues to complete the task and an increase in independence to complete the task. The decrease in number of cues required from baseline to end of data collection indicated clinically meaningful improvement in task completion. CONCLUSION Both VM and SP prompts resulted in an increase in independence in daily living skills, with most participants demonstrating improvement in either condition, indicating that the use of visual prompts (either VM or SP) is effective with the ASD population. Plain-Language Summary: Occupational therapy practitioners who work with autistic children and adolescents often identify improving daily living skills as a goal area. Findings from this study build on evidence that supports the use of a visual aid (either static picture or video modeling) to improve autistic children's acquisition of daily living skills. The findings also highlight emerging evidence related to the level of function and effectiveness associated with the type of visual cue. Positionality Statement: This article primarily uses identity-first language (i.e., autistic person) and at times person-first language (i.e., person with autism) to reflect the variability in the language preferences of the autism community (Lord et al., 2022).

Abstract
BACKGROUND Speech disorders have a substantial impact on communication abilities and quality of life. Traditional treatments such as speech and psychological therapies frequently demonstrate limited effectiveness and patient compliance. Transcranial electrical stimulation (TES) has emerged as a promising non-invasive treatment to improve neurological functions. However, its effectiveness in enhancing language functions and serum neurofactor levels in individuals with speech disorders requires further investigation. AIM To investigate the impact of TES in conjunction with standard therapies on serum neurotrophic factor levels and language function in patients with speech disorders. METHODS In a controlled study spanning from March 2019 to November 2021, 81 patients with speech disorders were divided into a control group (n = 40) receiving standard speech stimulation and psychological intervention, and an observation group (n = 41) receiving additional TES. The study assessed serum levels of ciliary neurotrophic factor (CNTF), glial cell-derived neurotrophic factor (GDNF), brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF), as well as evaluations of motor function, language function, and development quotient scores. RESULTS After 3 wk of intervention, the observation group exhibited significantly higher serum levels of CNTF, GDNF, BDNF, and NGF compared to the control group. Moreover, improvements were noted in motor function, cognitive function, language skills, physical abilities, and overall development quotient scores. It is worth mentioning that the observation group also displayed superior performance in language-specific tasks such as writing, reading comprehension, retelling, and fluency. CONCLUSION This retrospective study concluded that TES combined with traditional speech and psychotherapy can effectively increase the levels of neurokines in the blood and enhance language function in patients with speech disorders. These results provide a promising avenue for integrating TES into standard treatment methods for speech disorders.

Abstract
Executive dysfunction and other symptomatology could have links in preschoolers with autism spectrum disorder (ASD). This study contains three objectives: to explore the difference in executive function between preschoolers with ASD and typically developing individuals (TD), to investigate correlations between executive function and multiple domains of autism symptoms in preschoolers with ASD, and to examine the impact of executive function on symptoms of autism. Participants of this study included preschoolers (4-6 years) with ASD (24 boys, 20 girls) according to DSM-5-TR criteria and TD (24 boys, 20 girls). BRIEF-P (Behavior Rating Inventory of Executive Function-Preschool Version) and CASD-C (Checklist for Autism Spectrum Disorder-Chinese Version) were used as measurement tools. Data were analyzed using MANOVA, ANOVA, Pearson correlations, and simple regression. For the results, the study found results of executive function were significantly lower in preschoolers with ASD than in preschoolers without ASD; the greater the executive dysfunction, the greater the autistic symptomatology, and executive dysfunction predicted 57 % of the variability of autism symptoms. In conclusion, preschoolers with ASD had more executive dysfunction than those without ASD. Based on our findings, the study recommends incorporating executive function into clinical assessment programs to understand how executive function is related to autism symptoms.

Abstract
The interpersonal distance (IPD) theory provides a novel approach to studying autism spectrum disorder (ASD). In this article, we present recent findings on the neurobiological underpinnings of IPD regulation that are distinct in individuals with ASD. We also discuss the potential influence of environmental factors on IPD. We suggest that different IPD regulation may have implications for cognitive performance in experimental and diagnostic settings, may influence the effectiveness of training and therapy, and may play a role in the typical forms of social communication and leisure activities chosen by autistic individuals. We argue that reconsidering the results of ASD research through the lens of IPD would lead to a different interpretation of previous findings. Finally, we propose a methodological approach to study this phenomenon systematically.

Abstract
OBJECTIVE To describe the distribution of expressive language abilities of individuals with Down syndrome (DS) in a clinical sample and characterize demographic, environmental, and medical factors associated with varying expressive language profiles. METHODS Cross-sectional analysis was completed on a sample of 345 individuals with DS between the ages of 4 and 22 years who were enrolled into a longitudinal clinical database between March 2018 and August 2021. Expressive language-related items on a standardized caregiver-reported questionnaire assessing domains of functioning in neurodevelopmental disorders were used to conduct latent variable modeling and determine caregiver-reported expressive language (CREL) classes across the sample. Linear regression was used to explore associations between CREL classes and predictor variables. RESULTS Latent variable modeling revealed 3 distinct classes of CREL abilities representing higher, middle, and lower CREL. Individuals in the lower CREL class were more likely to be female, to use sign language or visual communication systems, have reduced pronunciation, attend private or residential school, and to be in a substantially separate classroom. Membership was not predicted by complex medical histories or co-occurring neurodevelopmental diagnoses. CONCLUSION Caregiver-reported expressive language abilities in a cohort of individuals with DS were variable, with most of the individuals belonging to higher or middle CREL classes, relative to one another. Additional studies are indicated to understand factors that predict higher expressive language ability and explore how to direct services to individuals who are at risk of more profound language delays.

Abstract
IMPORTANCE Youths with autism spectrum disorder (ASD) have challenges with executive function (EF). However, there are few measures to objectively assess EF, such as time management and prioritization. The Weekly Calendar Planning Activity (WCPA) is a promising performance-based EF measure that has rarely been used with youths with ASD. OBJECTIVE To characterize the performance of youths with ASD on the WCPA and the association of WCPA performance with caregiver-rated EF. DESIGN Observational and summary data obtained during a baseline evaluation for a research study. SETTING Middle school. PARTICIPANTS Thirty-nine adolescents with ASD and without an intellectual disability. METHOD Youth were administered the WCPA; caregivers completed EF ratings. Descriptive statistics characterized WCPA performance. Correlations between WCPA scores and age, IQ, and EF ratings were computed. RESULTS The majority of youth performed poorly on the WCPA and lacked insight into their poor performance. Many struggled to enter appointments. Appointment accuracy was <30%. The most common errors were location errors. Appointment accuracy and planning time were moderately associated with IQ but not with caregiver-rated EF or age. CONCLUSIONS AND RELEVANCE Overall, the WCPA was cognitively demanding for youths with ASD without an intellectual disability. These results have implications for using evidence-based strategies to teach adolescents with ASD how to manage their time and plan and prioritize homework assignments, upcoming tests or quizzes, and extracurricular activities. Plain-Language Summary: Youths with autism spectrum disorder have significant problems with executive function, particularly organization, prioritization, time management, and planning. There are few objective, performance-based measures of executive function, especially those that can be used with autistic youths. To our knowledge, this study is the first to use the Weekly Calendar Planning Activity (WCPA) with autistic adolescents who do not have an intellectual disability. The WCPA captured their deficits related to executive function and could be a useful tool for assessment and treatment planning.

Abstract
Background and aim Executive function (EF) impairment is common in children with autism spectrum disorder (ASD). EF strategies are considered effective in improving the therapeutic outcomes of children with ASD. This study primarily aimed to explore whether integrating EF strategies combined with regular occupational therapy intervention is more effective in improving daily life skills (DLS) and sensory integration/processing (SI/SP) skills than regular occupational therapy alone in children with ASD and secondarily aims to assess treatment outcomes on improving visual motor integration (VMI) skills. Methods A total of 17 participants (13 males, mean age 4.29 years, standard deviation 0.66) completed the study. Following the baseline assessments, the participants were randomly assigned to the treatment group (45-minute once-weekly individual occupational therapy plus EF strategies) or control group (45-minute once-weekly individual therapy sessions alone). All participants received one intervention per week for 14 weeks. All children were systematically evaluated using a pediatric functional independent measure (WeeFIM) and the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) to assess DLS, the Short Sensory Profile 2 (SSP2) to assess SP/SI, and the Beery VMI test (Beery VMI) to assess VMI. Assessments were conducted at baseline, seven weeks, and 14 weeks of treatment. Results The analysis of the results between the treatment and control groups revealed that the treatment group had greater gains and significant differences in the mean values of both the WeeFIM and SSP2. In addition, notable distinctions were observed in the VB-MAPP transition subscale; although these differences did not reach statistical significance, they were clinically significant. Minimal differences were noted in the VMI between the two groups. Nevertheless, both groups showed statistically significant improvements across all outcome measures. Conclusions Our study provides preliminary evidence of the efficacy of EF strategies combined with regular occupational therapy for DLS, SP/SI, and VMI in children with ASD. The differences between the groups support further evaluation of the effectiveness of EF strategies for the next stage of a larger randomized clinical trial.

Abstract
Executive functioning (EF) deficits, such as challenges with planning, organization, and materials management, negatively impact academic performance, particularly for middle-school students with autism spectrum disorder (ASD) without intellectual disability (ID). The aim was to assess the initial efficacy of the school-based version of the Achieving Independence and Mastery in School (AIMS) intervention in a pilot randomized clinical trial. 47 autistic middle-schoolers without ID attending nine different schools were randomized to participate in AIMS or to wait to receive AIMS the following semester (waitlist control = WLC). Youth, caregivers, and teachers rated academic EFs and academic functioning, and youth completed an objective EF measure, at baseline and outcome (post). Effect sizes were computed comparing baseline and post measures within each group. Individuals randomized to AIMS improved from baseline to post on academic EF outcome measures with small to moderate effect sizes, compared to WLC, who made some improvements but with generally smaller effect sizes. Analyses with academic functioning measures showed a similar pattern of results. These promising results suggest that AIMS delivered in the school by school-based personnel to small groups of students with ASD without ID can improve academic EF skills.

Abstract
Introduction Speech is one of the most important milestones to be achieved by a growing child. The significance of being informed about different pediatric speech abnormalities, especially to mothers, allows them to help their children in cases of irregularities in the maturation in this domain. Aim and objectives The study aimed to assess and educate mothers on the important milestones of speech delay in children and make them address the issue and be aware of various corrective measures to treat the underlying conditions of speech disorders in children. The objectives of the study include understanding the pre-acquired knowledge of the mothers regarding the delay in speech in children, imparting knowledge regarding different speech disorders and their management, spreading awareness on how to seek help for various underlying causes of speech irregularities or delay, and to train the mothers into approaching the challenges in an orderly manner. Methods A study was conducted to guide rural mothers visiting the Obstetrics and Gynecology and Pediatric out-patient departments and Neonatal wards in a rural tertiary care hospital situated in the Sawangi Meghe village of Wardha City, Maharashtra, India, about the detection and treatment of children with disabilities of speech as early as possible. The mothers' knowledge was assessed before and after the study with the help of questionnaires, and basic understandable information on different types, causes, symptomatology, and management of speech delay and disorders among children was explained with the help of group discussions and posters. Results The motive behind this study was to be aware of facts known by the rural mothers, their actions on coming across such presentations by their children, cues that they would pick up, and the need to ask for help at the appropriate time were assessed and elaborated if not known by them. The Relative Learning Gain and Normalized Gain were calculated to be 76.43% and 0.74 (high gain), respectively, and out of the total subjects, 97.16% of mothers voted that this study proved helpful, and six mothers (4.23%) benefited with the intervention and were referred to experts for evaluation of their children. Conclusion Awareness in this field is necessary to manage children's development, especially by their mothers. Knowing the prevalence of knowledge in mothers may build an association with the prevalence of the recognized cases of speech disorders in children. Evaluation at different community levels may be conducted to gauge the need to impart required knowledge about speech disabilities in children to the maternal population. Future research and the impartation of knowledge to caregivers are vital to promote vigilant and systematic action to be taken regarding the proper growth of their children.

Abstract
LAY ABSTRACT Executive functioning describes a set of cognitive processes that affect thinking and behavior. Past research has shown that autistic individuals often have delays in the acquisition of executive function abilities. Our study explored how differences in executive function and attention abilities relate to social abilities and communication/language in 180 young autistic children. Data were gathered via caregiver report (questionnaires/interviews) and an assessment of vocabulary skills. The ability to sustain attention to a dynamic video was measured via eye tracking. We found that children with higher levels of executive function skills demonstrated lower levels of social pragmatic problems, a measure of having difficulties in social contexts. Furthermore, children who were able to sustain their attention longer to the video displayed higher levels of expressive language. Our results emphasize the importance of executive function and attention skills across multiple areas of functioning in autistic children, in particular those that involve language and social communication.

Abstract
Background Pragmatic language weaknesses, a core feature of autism spectrum disorder (ASD), are implicated in externalizing behavior disorders (Gremillion & Martel, 2014). Particularly in a clinical setting, these co-occurring externalizing disorders are very common in autism; rates of Attentional Deficit-Hyperactive Disorder (ADHD) and Oppositional Defiant Disorder (ODD) are as high as 83% (ADHD) and 73% (ODD; Joshi et al., 2010). It is possible that pragmatic language weaknesses impact the ability to effectively communicate one's needs, which may lead autistic children to utilize externalizing behaviors in order to achieve a desired outcome (Ketelaars et al., 2010; Rodas et al., 2017). Methods The aim of the current study is to investigate the relationship between pragmatic language, assessed via multiple modalities, and externalizing behaviors, assessed by parent interview, in youth with autistic (n=33) or neurotypical (NT; n=34) developmental histories, along with youth diagnosed with autism, who lost the diagnosis (LAD) by adolescence (n=31). Results The autism group had significantly more pragmatic language difficulties, and more externalizing behaviors and disorders; ADHD symptoms were particularly more prevalent, while LAD and NT groups did not differ. Challenges in pragmatic language abilities were associated with more externalizing symptoms when controlling for other facts that typically influence such symptoms, including nonverbal cognition, structural language, executive functioning, and autistic characteristics, but did not remain when age was included in the model. Conclusions We discuss the mechanisms underlying difficult-to-manage externalizing behaviors and implications for interventions and long-term outcomes for youth with and without a history of autism.

Abstract
Introduction Little is known about cognitive control in adults with high-functioning forms of autism spectrum disorder because previous research focused on children and adolescents. Cognitive control is crucial to monitor and readjust behavior after errors to select contextually appropriate reactions. The congruency effect and conflict adaptation are measures of cognitive control. Post-error slowing, error-related negativity and error positivity provide insight into behavioral and electrophysiological correlates of error processing. In children and adolescent with autism spectrum disorder deficits in cognitive control and error processing have been shown by changes in post-error slowing, error-related negativity and error positivity in the flanker task. Methods We performed a modified Eriksen flanker task in 17 adults with high-functioning autism spectrum disorder and 17 healthy controls. As behavioral measures of cognitive control and error processing, we included reaction times and error rates to calculate congruency effects, conflict adaptation, and post-error slowing. Event-related potentials namely error-related negativity and error positivity were measured to assess error-related brain activity. Results Both groups of participants showed the expected congruency effects demonstrated by faster and more accurate responses in congruent compared to incongruent trials. Healthy controls exhibited conflict adaptation as they obtained performance benefits after incongruent trials whereas patients with autism spectrum disorder did not. The expected slowing in reaction times after errors was observed in both groups of participants. Individuals with autism spectrum disorder demonstrated enhanced electrophysiological error-processing compared to healthy controls indicated by increased error-related negativity and error positivity difference amplitudes. Discussion Our findings show that adults with high-functioning autism spectrum disorder do not show the expected upregulation of cognitive control in response to conflicts. This finding implies that previous experiences may have a reduced influence on current behavior in these patients which possibly contributes to less flexible behavior. Nevertheless, we observed intact behavioral reactions after errors indicating that adults with high-functioning autism spectrum disorder can flexibly adjust behavior in response to changed environmental demands when necessary. The enhancement of electrophysiological error-processing indicates that adults with high-functioning autism spectrum disorder demonstrate an extraordinary reactivity toward errors reflecting increased performance monitoring in this subpopulation of autism spectrum disorder patients.

Abstract
BACKGROUND AND OBJECTIVES Increasing evidence indicates a link between obesity and cognitive impairment. Furthermore, there is limited literature regarding the effect of polyphenols, a plant derived compounds, on executive functioning in an overweight/obese population at-risk of cognitive impairment. The aim of the present systematic review and meta-analysis of randomized controlled trials is to examine the effect of polyphenol supplementation on executive functions in overweight and/or obese populations at risk of cognitive impairment. METHODS A comprehensive literature search was conducted from inception to March 2023 using four electronic databases: PubMed/Medline, PsycInfo, Scopus and Cochrane trials library. Published primary research studies in English that compared the effect of polyphenols with placebo on executive function in overweight/obese adults were considered eligible for the meta-analysis. Jadad scale was used for the methodological quality rating of the included studies. Hedges g with 95% confidence intervals (CI) for endpoints were calculated using random effect model where applicable. Rosenthal's Fail-safe N, funnel plots, the Begg and Mazumdar's rank correlation test (Kendall's S statistic P-Q), Egger's linear regression test, and Duval and Tweedie's trim-and-fill test were identified for potential use as appropriate, to examine publication bias. Sensitivity analysis was conducted to examine the robustness of the results. RESULTS AND CONCLUSION A total of 23 RCT studies involving N = 1,976 participants were included in the review. The results of the meta-analysis revealed a non-significant effect for polyphenol supplementation on executive function (g = 0.076, CI = -0.018 to 0.170). Observations from primary studies within the meta-analysis showed a potential positive effect of polyphenol supplementation in a younger population at-risk of cognitive impairment and it is recommended to investigate this further in future studies. Moreover, the variability of the tasks used to examine executive functions as well as the adequate reporting of supplement's phenolic composition is a limitation that future work should also consider.

Abstract
Background Difficulties with narrative have been reported in individuals diagnosed with autism spectrum disorder (ASD), but the role of executive function on narrative ability has not been examined in ASD. In this study, we aimed to (1) examine whether narrative abilities of ASD children differed from neurotypical (NT) children who did not differ in age, sex, and IQ; and (2) investigate relations between executive function and narrative ability in ASD children. Method Narratives were elicited from 64 ASD children and 26 NT children using a wordless picture book and coded to derive several aspects of narrative ability such as propositions, evaluative devices, and self-repairs. Executive functions (specifically, inhibition and working memory) were measured using both experimenter-administered assessment and parent-report measures. Results Compared to NT children, ASD children produced fewer propositions but did not differ in their use of evaluative devices and self-repairs during narrative production. Greater inhibitory challenges related to more self-repairs involving repetition of story elements, whereas working memory did not relate to any of the measures of narrative ability among ASD children. Conclusions This study revealed that narratives by verbally fluent ASD children were shorter and less complex than those by NT children but did not differ in the specific features of narratives. Furthermore, although ASD children did not make more self-repairs than NT children, difficulty with inhibition was related to more self-repairs, indicating more dysfluent narrative production in ASD children, which has implications for intervention.

Abstract
This article reviews the current knowledge state on pragmatic and structural language abilities in autism and their potential relation to extralinguistic abilities and autistic traits. The focus is on questions regarding autism language profiles with varying degrees of (selective) impairment and with respect to potential comorbidity of autism and language impairment: Is language impairment in autism the co-occurrence of two distinct conditions (comorbidity), a consequence of autism itself (no comorbidity), or one possible combination from a series of neurodevelopmental properties (dimensional approach)? As for language profiles in autism, three main groups are identified, namely, (i) verbal autistic individuals without structural language impairment, (ii) verbal autistic individuals with structural language impairment, and (iii) minimally verbal autistic individuals. However, this tripartite distinction hides enormous linguistic heterogeneity. Regarding the nature of language impairment in autism, there is currently no model of how language difficulties may interact with autism characteristics and with various extralinguistic cognitive abilities. Building such a model requires carefully designed explorations that address specific aspects of language and extralinguistic cognition. This should lead to a fundamental increase in our understanding of language impairment in autism, thereby paving the way for a substantial contribution to the question of how to best characterize neurodevelopmental disorders.

Abstract
The aim of this study was to test and validate a parental-report questionnaire, which assesses language abilities and pragmatics, in children with Autism Spectrum Disorders (ASD). We report two experiments: The first served as the initial test and the second sought to provide the first assessment of convergent validity. In total, we recruited 230 parents, where approximately two-thirds had a child with ASD. Results of factor analyses showed a consistent factor structure within each subscale, and the internal consistency was excellent for both sub-scales (Cronbach's alpha >0.90). Convergent validity was assessed by correlating the results of the questionnaire with two sub-scales of the Autism Quotient questionnaire. The correlations were all greater than 0.60. The final version of the questionnaire (following exclusion of problematic items) contains 30 items (12 for language abilities and 18 for pragmatics). We conclude that the questionnaire is a concise and practical instrument for use in a variety of contexts for assessing language functioning and communication in children with ASD.

Abstract
The consolidation of learned information into long-lasting memories requires the strengthening of synaptic connections through de novo protein synthesis. Translation initiation factors play a cardinal role in gating the production of new proteins thereby regulating memory formation. Both positive and negative regulators of translation play a critical role in learning and memory consolidation. The eukaryotic initiation factor 4E (eIF4E) homologous protein (4EHP, encoded by the gene Eif4e2) is a pivotal negative regulator of translation but its role in learning and memory is unknown. To address this gap in knowledge, we generated excitatory (glutamatergic: CaMKIIα-positive) and inhibitory (GABAergic: GAD65-positive) conditional knockout mice for 4EHP, which were analyzed in various behavioral memory tasks. Knockout of 4EHP in Camk2a-expressing neurons (4EHP-cKOexc) did not impact long-term memory in either contextual fear conditioning or Morris water maze tasks. Similarly, long-term contextual fear memory was not altered in Gad2-directed 4EHP knockout mice (4EHP-cKOinh). However, when subjected to a short-term T-maze working memory task, both mouse models exhibited impaired cognition. We therefore tested the hypothesis that de novo protein synthesis plays a direct role in working memory. We discovered that phosphorylation of ribosomal protein S6, a measure of mTORC1 activity, is dramatically reduced in the CA1 hippocampus of 4EHP-cKOexc mice. Consistently, genetic reduction of mTORC1 activity in either excitatory or inhibitory neurons was sufficient to impair working memory. Taken together, these findings indicate that translational control by 4EHP and mTORC1 in both excitatory and inhibitory neurons are necessary for working memory.

Abstract
School-age children on the autism spectrum who are minimally verbal (MVAS) use a limited repertoire of spontaneous communicative spoken words and reveal large heterogeneity in cognitive functioning. Despite the challenges to form peer social engagement posed by their unique social-communicative profile, few interventions have targeted peer interactions in the MVAS population. This study explored predictors of individual differences in treatment response among 54 school-age minimally verbal autistic children (8-16 years) following an RCT "school-based peer social intervention" (S-PSI) that compared two peer-oriented intervention modalities (conversation versus collaboration) versus a waitlisted control group. We examined autistic-symptom severity, age, verbal and nonverbal IQ, executive functions, and sensory-processing profile for their contribution to children's ability to form relevant spontaneous communication exchanges with a peer partner. Main findings revealed that larger deficits in sensory-processing (sensory-avoidance and sensory low-registration) and in executive functions contributed to greater growth in "relevant" (i.e., adequately attuned, participatory, reciprocal) communication following both interventions, but not for the waitlisted controls. Additionally, older participants with lower verbal and nonverbal IQ improved communication's relevancy more after the conversation intervention, whereas the collaboration intervention was more beneficial for younger participants. Lower autistic-symptom severity contributed to larger growth in relevancy for all groups. By identifying individual-level predictors of spontaneous, attuned, participatory, and reciprocal (i.e., "relevant") communication exchanges with peers, we optimized S-PSI personalization for this uniquely nonverbal, heterogeneous MVAS population. These new channels for tailoring peer interventions to better meet individuals' needs may result in reduced social isolation and loneliness and enhanced well-being.

Abstract
We examined the cognitive flexibility performance of young autistic children and a group of neurotypical peers. Thirty-six autistic children (72-83 months) and 200 age-matched typically-developing children were assessed on the Children's Color Trails Test (CCTT), a semantic and a phonemic verbal fluency task. The results showed that the autistic children performed worse than their neurotypical peers in the switching component of the CCTT. In the fluency tests, the autistic group generated overall fewer word items than their neurotypical peers, however, their poorer performance was driven by specific linguistic stimuli in the fluency tasks. The findings suggest that cognitive flexibility for the autistic children was affected in the nonverbal CCTT only, while poor performance in semantic and phonemic fluency seemed to be inherent to the language properties of the verbal fluency tasks.

Abstract
Executive functions (EFs) serve as an umbrella term to describe a set of higher-order cognitive abilities that include working memory, inhibitory control, cognitive flexibility, planning, reasoning, and problem-solving. Various studies suggest that foreign language learning likely promotes executive functions, but others suggest that executive functions could improve foreign language learning. The aim of this study is to investigate the relationship between executive functions and foreign language learning and how these processes could interact. The sample included 64 children from kindergarten, aged 4-5 years, with no documented neuropsychiatric disorders, and from the middle-high literacy group. They were divided into three groups based on the level of their knowledge of the foreign language. A significant effect of the group on the executive tasks is shown in the comparison of the groups. Children who belonged to a group that had advanced foreign language proficiency had better results in executive tasks. Our results suggest that the higher the level of foreign language proficiency, the higher the performance of the executive tasks. However, we do not know if there is a causal effect between these variables.

Abstract
LAY ABSTRACT Executive functioning skills are important for children to be able to control thoughts, emotions, and actions, and for their ability to adapt to different settings. Previous studies have found that autistic children have difficulty with executive functioning, but most of these studies took place in the home setting. Executive functioning skills in autistic children have not yet been fully examined in the school setting. This is a knowledge gap that needs to be addressed because the school setting is potentially one of the most demanding in terms of executive functioning and is a setting where executive function interventions are already being used for autistic children. In order to learn more about executive functioning for autistic children in the school setting, this study compared ratings of executive function from autistic children's caregivers and school professionals. The study found that autistic children experience similar but not identical executive function challenges across school and home settings and that supports may differ in each setting. Having information about differences in executive functioning challenges and supports for autistic children across settings can help lead to development of supports that are tailored to each setting.

PlanTEA: Supporting Planning and Anticipation for Children with ASD Attending Medical Appointments. APPLIED SCIENCES-BASEL 2022.

Abstract
In people with Autism Spectrum Disorder (ASD), skills related to anticipation and mental flexibility are often impaired, so their thinking tends to be very rigid and their behavior is based on establishing routines. For this reason, children with ASD may show disruptive behaviors when faced with disturbing but necessary activities, such as going to a doctor’s appointment. Therefore, it is very convenient and necessary for their families to prepare in advance for the visit and to explain the details of the procedure to be performed at the consultation. The use of anticipation boards in these situations allows to prepare such situations and to reduce stress for both the ASD child and their families or caregivers. In this context, the use of technology can provide great benefits for anticipating a new event, or whatever risks the control of their routines, as well as enhancing developmental skills such as communication, autonomy, social interaction, etc. This article describes a software tool, for mobile devices such as tablets, that allows the planning of the attendance of children with ASD to the necessary medical appointments throughout their childhood and adolescence, as well as communication with specialists. This app, named PlanTEA, has undergone a preliminary evaluation that has yielded very positive results. Most participants found the app useful in helping to anticipate (94.1%) and improve communication (94.2%) for people with ASD in medical contexts, considered it easy to use, with no technical support needed to use it (almost 100%), and would recommend its use (94.2%). This first evaluation has also allowed us to define the next steps to be taken to improve and enhance this tool and thus reach a wider population within the autistic disorder. As a result of the evaluation carried out and the comments received, it is proposed to extend its use to adult users and those with high-functioning autism, which supposes expanding and extending the functionalities of the current version of PlanTEA.

Abstract
Dual diagnoses of autism spectrum disorders (ASDs) and stuttering have been reported in the literature, but little is known about how often they co-occur, the best practices for assessment, and even less about intervention. In this article, we gathered the data available on these issues and compiled and analyzed the sparse findings to offer suggestions for assessment and treatment. This article begins with a glossary of terms to promote consistency and understanding. Next, suggestions for assessment are provided along with a work sheet to document fluency breakdowns and monitor change. Suggestions for language and cognitive issues are also provided with a sample worksheet. Finally, an outline and explanation of stuttering/fluency goals for clients with these dual diagnoses are included. Case studies of two individuals who stutter and are diagnosed with ASD are presented to provide exemplars of how to assess and treat individuals with these dual diagnoses. Caveats on how to work with individuals with ASD and fluency disorders, based on our current understanding, are presented in the conclusion.

Abstract
The importance of time concept in human existence is "ancient history" celebrated in the biblical book Ecclesiastes. Indeed, our time-sensitive mechanisms are literally carved into our biology and neurology on a molecular level, gifting us with neural clocks. However, time in human consciousness is not the time indicated by physical clocks: time is a subjective reality in our psychological makeup due to the nature of the temporal neural mechanisms and unique properties of physical time. Nonetheless, subjective time requires anchoring to physical time which permeates our language, endeavors, and entire existence, a process hinging on time-related skills such as estimates and measures of passage and duration of time. Moreover, accurate time reading, a critical adaptive life-skill, is imperative for effective function in all societal activities. Because it embodies the complexity of the time construct, it is central to instruction of time concept in primary education. It is often measured in children by clock drawings, a cognitive integrative skill with errors pointing to neuroanatomical differences impacting the integrity of executive function. Time competence in children with atypical neurobiological development and high prevalence, as in autism spectrum disorders (ASD), and attention disorders (ADHD), is often compromised, calling for investigation of its function. This thematic review article aims to: 1) discuss the complexity of time concept and its underlying bio-neurological mechanisms, 2) elucidate difficulties children with ASD and those with ADHD exhibit in temporal development, and 3) demonstrate the use of a set of clinical tools in uncovering temporal competence and ecological executive function in two children with ASD, and a child with ADHD, using a clock drawing task and error analyses; children's time knowledge questionnaire; a behavior rating parent questionnaire examining ecological executive function, and parent open-ended questions related to their children's time difficulties. A discussion, directions, and a take-home message round out the article.

Abstract
BACKGROUND This study examined the association between executive functioning and language in young adults with Down syndrome (DS). METHOD Nineteen young adults with DS (aged 19-24 years) completed standardised measures of overall cognition, vocabulary, verbal fluency and executive function skills. RESULTS Friedman's analysis of variance (χ2 (3) = 28.15, P < .001) and post hoc comparisons indicated that, on average, participants had a significantly lower overall non-verbal than verbal cognitive age equivalent and lower expressive than receptive vocabulary skills. Using Spearman correlations, performance on a verbal measure of cognition inhibition was significantly negatively related to receptive vocabulary (ρ = -.529, adjusted P = .036) and verbal fluency (ρ = -.608, adjusted P = .022). Attention was significantly positively correlated with receptive (ρ = .698, adjusted-p = .005) and expressive (ρ = .542, adjusted P = .027) vocabulary. Verbal working memory was significantly positively associated with receptive vocabulary (ρ = .585, adjusted P = .022) and verbal fluency (ρ = .737, adjusted P = .003). Finally, visuospatial working memory was significantly associated with receptive vocabulary (ρ = .562, adjusted P = .027). CONCLUSIONS Verbal and non-verbal measures of executive functioning skills had important associations with language ability in young adults with DS. Future translational research is needed to investigate causal pathways underlying these relationships. Research should explore if interventions aimed at increasing executive functioning skills (e.g. attention, inhibition and working memory) have the potential to lead to increases in language for young adults with DS.

Abstract
Williams Syndrome (WS) is a rare genetic multisystem disorder that occurs because of a deletion of approximately 25 genes in the 7q11.23 chromosome region. This causes dysmorphic facial appearances, multiple congenital cardiovascular defects, delayed motor skills, and abnormalities in connective tissues and the endocrine system. The patients are mostly diagnosed with mild to moderate mental retardation, however, they have a hyper sociable, socially dis-inhibited, and outgoing personality, empathetic behavior, and are highly talkative. Oxytocin (OT), a neuropeptide synthesized at the hypothalamus, plays an important role in cognition and behavior, and is thought to be affecting WS patients' attitudes at its different amounts. Oxytocin receptor gene (OXTR), on chromosome 3p25.3, is considered regulating oxytocin receptors, via which OT exerts its effect. WS is a crucial disorder to understand gene, hormone, brain, and behavior associations in terms of sociality and neuropsychiatric conditions. Alterations to the WS gene region offer an opportunity to deepen our understandings of autism spectrum disorder, schizophrenia, anxiety, or depression. We aim to systematically present the data available of OT/OXTR regulation and expression, and the evidence for whether these mechanisms are dysregulated in WS. These results are important, as they predict strong epigenetic control over social behavior by methylation, single nucleotide polymorphisms, and other alterations. The comparison and collaboration of these studies may help to establish a better treatment or management approach for patients with WS if backed up with future research.

Abstract
BACKGROUND Autism Spectrum Disorder is often associated with deficits in executive functions (EFs), which is contributing significantly to individuals with ASD's difficulties in conducting an independent life, particularly considering social skills. Technologies offer promising opportunities to structure EF intervention programs for children on the autistic spectrum. METHODS This study aimed to review the effectiveness of randomized controlled trials or quasi-experimental studies of EF interventions delivered to children and young people (up to 23 years old) with a diagnosis of ASD. A special focus was dedicated to document the effectiveness of computerized and non-computerized cognitive training on (1) EFs and on (2) ASD symptomatology and social skills. Of 2601 studies retrieved, 19 fulfilled the inclusion criteria. RESULTS Most of the interventions identified were effective in enhancing EFs and reducing symptoms in children and young people with ASD. Limited evidence is available on their generalization to untrained skills (i.e., social abilities) as well as long-term effects. CONCLUSIONS There is growing evidence for overall effectiveness of EF training, particularly when computerized. However, caution should be taken when interpreting these findings owing to methodological limitations, the minimal number of papers retrieved, and a small samples of included studies.

Abstract
Deficits in working memory have not been fully explored in toddlers and preschoolers with autism spectrum disorder (ASD). We investigated the relationship between language (verbal ability, verbal self-talk) and visuospatial working memory in 2- and 4-year-olds with ASD (n = 65) and typical development (TD) (n = 54). Children with ASD displayed impairments in working memory and verbal ability, but not verbal self-talk, compared to TD peers. Verbal ability and working memory were positively correlated; this association was stronger for children with ASD. For 2-year-olds, self-talk and working memory were negatively correlated. Results suggest that verbal ability and working memory are linked, especially for young children with ASD. Self-talk may be a compensatory strategy for toddlers with less developed working memory.

Abstract
Theory of mind (ToM) refers to the ability to infer others' mental states. In our everyday lives, we need to interact constantly and appropriately with others. Not only is ToM involved in understanding others' mental states (other-oriented mental inferences), but it also helps to keep our own mental states (self-oriented mental inferences). In this study, we designed a false-belief task using event-related potential (ERP) measures to investigate the dynamic differences between the two types of mental inferences. In the false-belief task, participants were prompted with a cue to attribute a belief to either themselves (self-oriented) or another person (other-oriented). Results showed that other-oriented false-belief attribution elicited a larger late positive component (LPC; 320~440 ms post-cue onset) than the one elicited by self-oriented attribution at bilateral parieto-occipital electrodes, and also a larger late negative component (LNC; 380~500 ms post-cue onset) at frontal-central electrodes. In addition, the difference in amplitude of LPC between the two types of false-belief attribution was positively correlated with self-reported autistic traits measured by the Autism Spectrum Quotient (AQ). Based on prior literature, we propose that the LPC and LNC reflect the processes of self-other distinction and conflict control, respectively. Moreover, the difficulty in distinguishing other from the self is related to one's degree of autistic traits.

Abstract
OBJECTIVE To describe the effect of prednisolone on language in children with autism spectrum disorder. This study is based upon two hypotheses: autism etiology may be closely related to neuroinflammation; and, an effective treatment should restore the individual's language skills. METHOD This is a prospective, double-blinded, randomized, placebo-controlled clinical trial, carried out in a federal university hospital. The initial patient sample consisted of 40 subjects, which were randomized into two parallel groups. Inclusion criteria were: male gender, 3-7 years of age, and meeting the Diagnostic and Statistical Manual of Mental Disorders - 4th edition (DSM-IV) diagnostic criteria. The final sample consisted of 38 patients, of whom 20 were randomized to the placebo group and 18 to the active group. The latter received prednisolone for 24 weeks, at an initial dose of 1mg/kg/day and a tapering dose from the ninth week onward. Language was measured on four occasions over a 12-month period by applying two Brazilian tools: the Language Development Assessment (ADL) and the Child Language Test in Phonology, Vocabulary, Fluency, and Pragmatics (ABFW). RESULTS The side effects were mild: two patients had hypertension, five had hyperglycemia, and two had varicella. Prednisolone increased the global ADL score in children younger than 5 years of age who had developmental regression (p=0.0057). The ABFW's total of communicative acts also responded favorably in those participants with regression (p=0.054). The ABFW's total of vocal acts showed the most significant results, especially in children younger than 5 years (p=0.004, power=0.913). CONCLUSIONS The benefit of prednisolone for language scores was more evident in participants who were younger than five years, with a history of developmental regression, but the trial's low dose may have limited this benefit. The observed side effects do not contraindicate corticosteroid use in autism.

Abstract
Several theories propose that one of the core functions of inner speech (IS) is to support subjects in the completion of cognitively effortful tasks, especially those involving executive functions (EF). In this paper we focus on two populations who notoriously encounter difficulties in performing EF tasks, namely, people diagnosed with schizophrenia who experience auditory verbal hallucinations (Sz-AVH) and people with autism spectrum conditions (ASC). We focus on these two populations because they represent two different ways in which IS can fail to help in EF tasks, which can be illustrative for other mental conditions. First, we review the main components of EF (see section "Executive Functions"). Then we explain the functions that IS is taken to perform in the domain of EF (see section "Inner Speech and Executive Functions") and review the evidence concerning problems about EF in the two populations of our study: Sz-AVH (see section "Executive Functions and Inner Speech in Sz-AVH") and ASC (see section "Executive Function and Inner Speech in ASC"). After this we further detail our account about what a properly functioning IS can do for both populations and how different IS profiles may impact EF performance: in the case of Sz-AVH, the uncontrolled and intrusive character of IS negatively affects EF performance, whereas in ASC, EF is not sufficiently supported by IS, given the tendency in this population to present a diminished use of IS (see section "IS in ASC and Sz-AVH: How It Relates to EF"). We finally briefly discuss Attention Deficit/Hyperactivity Disorder (ADHD) and Developmental Language Disorders (DLD) (see section "Further Considerations").
