RESUMEN

Background: Interactive telemedicine applications have been progressively introduced in the assessment of cognitive and literacy skills. However, there is still a lack of research focusing on the validity of this methodology for the neuropsychological assessment of children with Specific Learning Disorder (SLD). Methods: Seventy-nine children including 40 typically developing children (18 males, age 11.5 ± 1.06) and 39 children with SLD (24 males, age 12.3 ± 1.28) were recruited. Each participant underwent the same neuropsychological battery assessing reading accuracy, speed, and comprehension, writing, numerical processing, computation, and semantic numerical sense, twice (once during an in-person session (I) and once during a remote (R) home-based videoconference session). Four groups were subsequently defined based on the administration order. Repeated-measure-ANOVAs with assessment type (R vs. I testing) as within-subject factor and diagnosis (SLD vs. TR) and administration order (R-I vs. I-R) as between-subject factors, and between-group t-tests comparing the two assessment types within each time of administration, were run. Results: No differences emerged between I and R assessments of reading accuracy and speed, numerical processing, and computation; on the contrary, potential biases against R assessment emerged when evaluating skills in writing, reading comprehension, and semantic numerical sense. However, regardless of the assessment type, the scores obtained with I and R assessments within the same administration time point overlapped. Discussion: These results partially support the validity and reliability of the assessment of children's learning skills via a remote home-based videoconferencing system. Implementing telemedicine as an assessment tool may increase timely access to primary health care and to support research activity.

RESUMEN

Executive function (EF) in specific learning disorders (SLD) has been investigated using mainly cool EF tasks, whilst less is known about hot EF and theory of mind (ToM) in this population. The aim of this study was to examine group differences in hot and cool EF and ToM in school-aged children with SLD relative to typically developing peers. It also attempted to investigate whether EF measures are significant predictors of ToM in SLD and typical development. Cross-sectional data were collected from 135 school-aged children with and without SLD (8-10 years old), tested on measures of cool & hot EF and ToM. Significant group differences were observed in EFs inhibition (p= .04), working memory (p= .04) and delay of gratification (p < .001), as well as ToM mental state/emotion recognition (p = .019). Inhibition and planning contributed to 22% of the explained variance of ToM mental state/emotion recognition, but not false belief overall. Results suggest that cool EF may be a crucial predictor of ToM in children with and without SLD. Finally, stepwise logistic regression analysis identified specific hot EF and ToM measures contributing to group differentiation, specifically delay of gratification (odds ratio=.995, 95% CI [.993-.998]) and mental state/emotion recognition (odds ratio= .89, 95% CI [.796-.995]). This study contributes to our understanding of cognitive deficits and socio-cognitive impairment in children with SLD, which hold promise for informing interventions aimed at addressing these cognitive challenges.

RESUMEN

Learning to read and write are essential academic skills that children develop during their early years of primary school. These skills are supported by various predictive indices that emerge in early childhood. This review has three main goals: to identify which factors are closely examined as predictors for reading and writing, specifically decoding and encoding skills, in different populations and languages (Objective 1); to assess the longitudinal relationship between these predictors and reading and writing skills (Objective 2), considering difficulties or disorders in these areas (Objective 3), during school-age. Using the PRISMA methodology, 81 articles were reviewed. As a first result, there is a significant difference in the number of studies investigating the relationship between predictors and reading (n = 75) compared to writing (n = 18). The most extensively studied predictors for both skills are phonological awareness, language skills, executive functions, rapid automatized naming, and non-verbal cognitive skills. English is the most studied language. Results indicated variability in the relationship between predictors and reading/writing, possibly due to differences in the analyzed populations, chosen outcome measures, and statistical analyses. Additionally, few studies explored the long-term connection between predictors and learning difficulties. In summary, recognizing the multifaceted nature of predictive factors for reading and writing is crucial, and early screening is important for tailored preventive interventions in case of early deficiencies. Future research should delve into writing, conduct cross-cultural studies with diverse languages, and explore the role of predictive factors in understanding reading and writing difficulties or disorders.

RESUMEN

Proper treatment of developmental disabilities requires health workers to have adequate knowledge of etiology and referral procedures. There is a dearth of research on knowledge of developmental disabilities among health workers in Ghana. The purpose of this study was to document knowledge about developmental disorders, causes, and referral procedures among health workers. Researchers used a successive free-listing method to interview 37 health workers. Developmental disabilities which present with physical symptoms were the most salient disorders identified among health workers, while learning disabilities and attention deficit disorder were largely overlooked. The most commonly listed developmental disabilities were cerebral palsy, Down syndrome, and autism spectrum disorder. Respondents had limited knowledge about the causes of and referral resources for developmental disabilities. Results show the need for continuing medical education, public awareness, and enhanced resources to support the identification and care of children with developmental disabilities in Ghana.

RESUMEN

An emerging body of research utilizes music in the treatment of children with specific learning disorders in reading. However, greater understanding of music interventions is necessary for efficient application of music to address children's specific reading needs. Therefore, this scoping review aimed to identify the key musical concepts used to improve reading skills. Intervention studies were identified through online searches of databases and hand searching of primary journals in music therapy, and 12 studies met the inclusion criteria. For the 12 studies, auditory processing, phonological processing, and temporal processing were the underlying mechanisms identified in the interventions. Most of the interventions presented rhythmic activities for the purpose of improving reading accuracy. The results of this study highlight the lack of specific descriptions for the musical elements used within music interventions targeting reading skills. In addition, due to the diversity of the terms used to describe the music interventions, it was difficult to compare the effectiveness of these interventions on reading accuracy, comprehension skills, and fluency. Therefore, future studies are needed to articulate clear rationales for how musical elements can be used in music interventions to treat specific reading disabilities in children.

RESUMEN

BACKGROUND: Attention Deficit/Hyperactivity Disorder (ADHD) is one of the most common disorders in school-aged children. Learning disorder (LD) is also one of the most important psychiatric disorders in children, which can often be associated with ADHD. In this study, we sought to compare self-esteem and quality of life in 8 to 12-year-old children with attention deficit/hyperactivity disorder with and without co-occurring learning disorders in order to emphasize the importance of attention and diagnosis in children with ADHD. METHOD: Among the 8- to 12-year-old outpatients referred to the child and adolescent psychiatry clinic of Omid Babol Clinic, 120 children aged 8 to 12 years with attention deficit/hyperactivity disorder whose disease was diagnosed by a child and adolescent psychiatry subspecialist. Among the tools used to collect information was the Colorado Learning Difficulties Questionnaire by Wilcott et al. (CLDQ), five-scale self-esteem test of Pepe et al. (1989) for children and quality-of-life questionnaire for 8-12-year-old children (PedsQL). RESULTS: This study investigated self-esteem and quality of life in children with ADHD (n = 120, 51.7% boys). Children with ADHD and learning disabilities reported significantly lower self-esteem and quality of life compared to those with ADHD alone. CONCLUSION: Considering the relatively high probability of co-occurrence of ADHD and learning disorders, if one of them is diagnosed in a child, it is possible to look for other disorders in the child in order to avoid the more severe negative effects that this co-occurrence can have on the child by diagnosing it as soon as possible.

RESUMEN

Background and Objectives: Neurodevelopment is a fragile brain process necessary for learning from the beginning of childhood to adulthood. During the procedure, several risks could affect it, including environmental factors such as neurotoxic chemicals or environmental pollutants and, within them, exposure to pesticides. Materials and Methods: This ecological descriptive study attempted to assess the association between environmental exposure to pesticides and neurodevelopmental disorders. This study was conducted on 4830 children diagnosed for 11 years in a total population of 119,897 children in three areas: high, medium, and low greenhouse concentrations. Results: Chromosomal abnormalities were the most common prenatal disorder (28.6%), while intrauterine physical factors were the least common (0.5%). Among perinatal diagnoses, gestational age less than 32 weeks was the most common (25%), while hyperbilirubinemia requiring exchange transfusion and birth complications was the least common (0.4%). Brain damage was the most common problem detected in postnatal diagnosis (36.7%), while unspecified postnatal abnormalities were the least common (3.1%). Conclusions: The areas with the highest greenhouse concentration had higher incidences of neurodevelopmental disorders, particularly in boys, and lower age of referral. Chromosomal abnormalities were prevalent for prenatal diagnoses, gestational age below thirty-two weeks for perinatal diagnoses, and brain damage for postnatal diagnoses. Future studies should analyze the connection between pesticide exposure and neurodevelopmental disorders using spatial point pattern analysis.

RESUMEN

Background: Developmental Dyslexia (DD) is a brain-based developmental disorder causing severe reading difficulties. The extensive data on the neurobiology of DD have increased interest in brain-directed approaches, such as transcranial direct current stimulation (tDCS), which have been proposed for DD. While positive outcomes have been observed, results remain heterogeneous. Various methodological approaches have been employed to address this issue. However, no studies have compared the effects of different transcranial electrical stimulation techniques (e.g., tDCS and transcranial random noise stimulation, tRNS), on reading in children and adolescents with DD. Methods: The present within-subject, double-blind, and sham-controlled trial aims to investigate the effects of tDCS and hf-tRNS on reading in children and adolescents with DD. Participants will undergo three conditions with a one-week interval session: (A) single active tDCS session; (B) single active hf-tRNS session; and (C) single sham session (tDCS/hf-tRNS). Left anodal/right cathodal tDCS and bilateral tRNS will be applied over the temporo-parietal regions for 20 min each. Reading measures will be collected before and during each session. Safety and blinding parameters will be recordered. Discussion: We hypothesize that tRNS will demonstrate comparable effectiveness to tDCS in improving reading compared to sham conditions. Additionally, we anticipate that hf-tRNS will exhibit a similar safety profile to tDCS. This study will contribute novel insights into the effectiveness of hf-tRNS, expediting the validation of brain-based treatments for DD.

RESUMEN

BACKGROUND: During the COVID-19 pandemic, France faced a 2-month lockdown in 2020, marked by numerous restrictions. This study aimed to examine the experience and management of children aged 6-17 years with learning and/or attention disorders during the first lockdown. METHODS: We conducted an observational, retrospective study, with data collection from March 1 to May 31, 2021, by means of an anonymous digital qualitative questionnaire completed by parents. The experience of confinement as well as the children's behavior, schooling, and level of progress during rehabilitation were assessed by parents through a Likert scale. Data were compared according to two groups: negative experience and positive or neutral experience of the child's confinement. RESULTS: A total of 251 questionnaires were collected and 217 were analyzed. Overall, 47 children (21.7 %) reported a negative experience of the confinement period. In total, 164 (75.6 %) of the children had their schooling monitored throughout the period; half of the parents reported a course format unsuited to their child's disorders and a lack of motivation, and 46.5 % a refusal by their child to study. Only 16.8 % of parents reported a regression in their child's rehabilitation. These last three results were significantly associated with a poor experience of confinement (p < 0.05). CONCLUSION: The period of confinement was experienced relatively well by the children, and the rehabilitative management seemed to have been minimally impacted during this period. The therapeutic education of children, their parents, and also teachers is a major axis of improvement for better care and support of children with these disorders.

RESUMEN

Youth with different developmental disorders might experience challenges when dealing with facial emotion recognition (FER). By comparing FER and related emotional and cognitive factors across developmental disorders, researchers can gain a better understanding of challenges and strengths associated with each condition. The aim of the present study was to investigate how social anxiety and executive functioning might underlie FER in youth with and without autism spectrum disorders (ASD) and specific learning disorders (SLD). The study involved 263 children and adolescents between 8 and 16 years old divided into three groups matched for age, sex, and IQ: 60 (52 M) with ASD without intellectual disability, 63 (44 M) with SLD, and 140 (105 M) non-diagnosed. Participants completed an FER test, three executive functions' tasks (inhibition, updating, and set-shifting), and parents filled in a questionnaire reporting their children's social anxiety. Our results suggest that better FER was consistent with higher social anxiety and better updating skills in ASD, while with lower social anxiety in SLD. Clinical practice should focus on coping strategies in autistic youth who could feel anxiety when facing social cues, and on self-efficacy and social worries in SLD. Executive functioning should also be addressed to support social learning in autism.

RESUMEN

Despite the abundant literature on intelligence and high potential individuals, there is still a lack of international consensus on the terminology and clinical characteristics associated to this population. It has been argued that unstandardized use of diagnosis tools and research methods make comparisons and interpretations of scientific and epidemiological evidence difficult in this field. If multiple cognitive and psychological models have attempted to explain the mechanisms underlying high potentiality, there is a need to confront new scientific evidence with the old, to uproot a global understanding of what constitutes the neurocognitive profile of high-potential in gifted individuals. Another particularly relevant aspect of applied research on high potentiality concerns the challenges faced by individuals referred to as "twice exceptional" in the field of education and in their socio-affective life. Some individuals have demonstrated high forms of intelligence together with learning, affective or neurodevelopmental disorders posing the question as to whether compensating or exacerbating psycho-cognitive mechanisms might underlie their observed behavior. Elucidating same will prove relevant to questions concerning the possible need for differential diagnosis tools, specialized educational and clinical support. A meta-review of the latest findings from neuroscience to developmental psychology, might help in the conception and reviewing of intervention strategies.

RESUMEN

RESUMO Este artigo apresenta os resultados de uma pesquisa que consistiu em analisar o uso do audiobook como recurso tecnológico de ensino para estudantes com dislexia na área de língua portuguesa. A pesquisa contemplou uma abordagem qualitativa, caracterizada como descritiva, da qual participaram 53 estudantes do Ensino Médio, divididos em duas turmas, e seus respectivos professores. Como instrumentos de pesquisa, foram utilizados: diário de bordo, questionários e uma sequência didática que contou com a utilização do livro e audiobook Auto da Compadecida, de Ariano Suassuna. Os resultados destacaram que utilizar o recurso audiobook pode beneficiar a leitura nas aulas de língua portuguesa e em outras disciplinas, promovendo o engajamento dos discentes com e sem dislexia, aumentando a participação e a interação durante as aulas. Ao comparar-se a participação dos estudantes em momentos com e sem o uso do audiobook, ficou evidente que o uso dessa tecnologia foi amplamente aceito pelos participantes. Embora os audiobooks estejam disponíveis em várias plataformas gratuitas, muitos estudantes e até mesmo professores revelaram não conhecer ou nunca os terem utilizado. A utilização de recursos tecnológicos pode potencializar o processo de ensino de aprendizagem, introduzindo dinamismo e tornando o conteúdo mais acessível para estudantes que buscam alternativas inovadoras para o estudo.


ABSTRACT This article presents the results of a research that consisted of analyzing the use of the audiobook as a teaching technological resource for students with dyslexia in the Portuguese language area. The research included a qualitative approach, characterized as descriptive, in which 53 High School students participated, divided into two groups, and their respective teachers. As research instruments, the following were used: logbook, questionnaires and a didactic sequence that included the use of the book and audiobook Auto da Compadecida, by Ariano Suassuna. The results highlighted that using the audiobook resource can benefit reading in Portuguese language classes and in other subjects, promoting the engagement of students with and without dyslexia, increasing participation and interaction during classes. Ao comparar-se a participação dos estudantes em momentos com e sem o uso do audiobook, ficou evidente que o uso dessa tecnologia foi amplamente aceito pelos participantes. When comparing the participation of the students during the moments with and without using the audiobook, it was evident that the use of this technology was widely accepted by the participants. Although audiobooks are available on several free platforms, many students and even teachers revealed that they did not know or had never used them. The use of technological resources can enhance the teaching and learning process, introducing dynamism and making the content more accessible to students who seek innovative alternatives for studying.

RESUMEN

Specific learning disorders (SLDs) are the most frequently diagnosed developmental disorders in childhood. Different neurocognitive patterns have been found in patients with overweight and obesity, but no data on childhood obesity and SLDs have been reported. To increase our understanding of the relationship between neuropsychological developmental and obesity, we assessed the prevalence of SLD in a pediatric population with obesity. We retrospectively included 380 children and adolescents with obesity. For all participants, auxological, metabolic, demographic features, relationship and social skills, anamnestic data on pregnancy and the perinatal period, stages of development and family medical history were reviewed. SLD was defined according to the DSM-5 criteria. A group of 101 controls of normal weight was included. The overall prevalence of SLD was 10.8%, and SLD was more prevalent in patients with obesity (p < 0.001), with male predominance (p = 0.01). SGA was associated with SLD (p = 0.02). Speech retardation (p < 0.001), limited relationships with peers (p < 0.001) and didactic support (p < 0.001) were noted in the SLD group compared to the group without SLD. A higher prevalence of family history of neuropsychiatric disorders was observed in the SLD group (p = 0.04). A higher fasting glucose level was detected in patients with obesity and SLD compared to subjects without SLD (p = 0.01). An association between obesity and SLD could not be excluded, and an overlap of pathogenic factors for both conditions should be considered.

RESUMEN

Executive Functions (EFs) are high-order cognitive processes relevant to learning and adaptation and frequently impaired in children with specific learning disorders (SLDs). This study aimed to investigate EFs in children with SLD and explore the role of specific EF-related subprocesses, such as stimuli processing and processing speed. Fifty-seven SLD and 114 typically developing (TD) children, matched for gender and age, completed four tasks measuring response inhibition, interference control, shifting, and updating on a web-based teleassessment platform. The results show that SLD children performed lower in all EF tasks than TD children, regardless of stimulus type and condition. Mediation analyses suggested that differences between the SLD and TD groups are mediated by EF-related subprocesses, offering an interpretative model of EF deficits in children with SLD.

RESUMEN

Background: The application of Virtual Reality (VR) in the field of rehabilitation has been widely studied, because it has already proven to be an effective intervention for a variety of physical and cognitive conditions. Nevertheless, its application in pediatric rehabilitation is more recent. This pilot study aims to examine whether a VR-rehabilitation program may have positive effects on the Executive Functions (EFs) of children with Specific Learning Disorders (SLD). Materials and methods: Twenty-four children with diagnosis of SLD participated to the study (range 7-11 years) and performed the VR-training across 6 weeks in the CARE Lab, that was designed with appropriate structural measures and ad hoc fittings, to hide the sophisticated technology necessary to allow the child to experience a rehabilitative setting with recreational and semi-immersive features. Children were evaluated across three main time-points: T0, assessment of cognitive level and EFs immediately before the start of the intervention; T1, assessment of EFs immediately after the end of VR intervention; T2, follow-up of EFs after 6 months from the end of the VR intervention. The rehabilitation programs were customized according to clinical needs and/or single patient's characteristics, proposing different games with variable complexity levels. Results: Results showed that scores for visual attention, inhibition, flexibility, and planning abilities were significantly higher than before the intervention, and the most part of these ameliorations were maintained after 6 months. Conclusion: These findings provide important inputs for the development of new innovative rehabilitation interventions for children with SLD that must be founded in ecological and evidence-based approaches.

RESUMEN

Neurodevelopmental disorders appear to be rising in prevalence, according to the recent Global Burden of Disease Study. This rise is likely to be multi-factorial, but the role of certain nutrients known to facilitate neurodevelopment should be considered. One possible contributing factor could be attributed to deficits in choline intake, particularly during key stages of neurodevelopment, which includes the first 1000 days of life and childhood. Choline, a key micronutrient, is crucial for optimal neurodevelopment and brain functioning of offspring. The present narrative review discusses the main research, describing the effect of choline in neurodevelopmental disorders, to better understand its role in the etiology and management of these disorders. In terms of findings, low choline intakes and reduced or altered choline status have been reported in relevant population subgroups: pregnancy (in utero), children with autism spectrum disorders, people with attention deficit hyperactivity disorder and those with dyslexia. In conclusion, an optimal choline provision may offer some neuronal protection in early life and help to mitigate some cognitive effects in later life attributed to neurodevelopmental conditions. Research indicates that choline may act as a modifiable risk factor for certain neurodevelopmental conditions. Ongoing research is needed to unravel the mechanisms and explanations.

RESUMEN

Children with learning disorders (LD children) often have heterogeneous cognitive impairments that affect their ability to learn and use basic academic skills. A proposed cause for this variability has been working memory (WM) capacity. Altered patterns of event-related potentials (ERPs) in these children have also been found in the N400 component associated with semantic priming. However, regarding the semantic priming effect in LD children, no distinction has been made for children with varying WM abilities. This study aims to explore the relationship of WM with the brain's electrophysiological response that underlies semantic priming in LD children that performed a lexical decision task. A total of 40 children (8-10 years old) participated: 28 children with LD and 12 age-matched controls. The ERPs were recorded for each group and analyzed with permutation-based t-tests. The N400 effect was observed only in the control group, and both groups showed a late positive complex (LPC). Permutation-based regression analyses were performed for the results from the LD group using the WISC-IV indices (e.g., Verbal Comprehension and WM) as independent predictors of the ERPs. The Verbal Comprehension Index, but not the WM index, was a significant predictor of the N400 and LPC effects in LD children.

RESUMEN

The impact of psychiatric comorbidities in the diagnosis and treatment of feeding and eating disorders (FEDs) represents an emerging research topic. The current literature, nonetheless, lacks studies investigating the developmental paths of individuals with FEDs and comorbid neurodevelopmental disorders (NDDs). Here, we report 11 cases of children and adolescents with comorbid FEDs and NDDs, as assessed along the neuropsychological, psychopathological, and nutritional developmental pathways. The onset of FED-related psychopathology was preceded, sometimes undiagnosed, by altered neurodevelopmental features leading to specific NDD diagnoses (autism spectrum disorder-ASD; attention-deficit/hyperactivity disorder-ADHD; specific learning disorder-SLD). NDDs appeared to influence the diagnoses and treatments of FEDs, frequently with an impact on socio-relational and emotional premorbid features, and on the possibility to receive and attend FED-targeted treatments. Further studies should longitudinally contribute to assessing the experiences of care and neurodevelopmental pathways of children with FEDs and specific NDD comorbidities.

RESUMEN

Specific Learning Disorder (SLD) is a complex disorder with a strong genetic component, characterized by varying manifestations and considerable differences among children. Several studies have highlighted that difficulties in language acquisition and the presence of Developmental Language Disorders (DLDs) are frequently associated with SLD, suggesting a continuity between the two disorders. This study aimed to add evidence on the proximal and distal predictors of SLD, focusing on the eventual continuity for the presence of DLD at 4-5 years, on some linguistic and communicative abilities at 27-30 months, and on biological and environmental factors. Our sample consisted of 528 families, whose children (Italian monolingual) participated in a screening program at the age of 27-30 months. When children were on average 8.05 years old, parents were asked to answer an interview aimed at collecting information about the children's language and learning development. Results showed that the prevalence of children with an SLD (7.01%) was in line with those reported in other similar studies. The diagnosis of SLD was significantly predicted by the previous diagnosis of DLD, by male sex/gender, and by the familial risk of SLD. Children with these characteristics had a 54% probability of presenting an SLD.

RESUMEN

Introduction: Past research has demonstrated that attention-deficit/hyperactivity disorder (ADHD), specific learning disorders (SLD), and socioeconomic status (SES) affect a host of educational outcomes. However, there are no studies examining whether SES moderates the association between these neurodevelopmental disorders (ND) and the academic achievement of children and adolescents. The present investigation examined the impact of ADHD and SLD on academic performance in 1,287 Spanish students aged 5-17 from a low-middle (LM)- and a high-income population, when adjusted for comorbidity and demographic factors that may influence educational functioning. Methods: Parents completed a questionnaire regarding demographic data along with the Strengths and Difficulties Questionnaire. Additionally, teachers provided information on learning difficulties trough the Protocol for Detection and Management of Dyslexia. Teacher's Version. Academic performance across multiple domains (i.e., first language, foreign language, mathematics) was obtained from school records. ND were determined using standardized diagnostic methods based on the Diagnostic and Statistical Manual of Mental Disorders criteria. To examine the effects of ADHD and SLD on academic achievement and the potential moderating role of SES, a series of ordinal logistic regressions were conducted. Results: Emotional/behavioral problems, learning difficulties, and ND were more frequent among individuals from the LM-income population. After controlling for gender, age, parental divorce/separation, grade retention, frequency of screen use, and daily meals, both ADHD and SLD were associated with worse educational outcomes. Lower SES also increased the risk for academic impairment, although the interactions with ADHD or SLD were not significant. Conclusion: These findings indicate that ADHD and SLD exert a pervasive impact on academic performance across different socioeconomic backgrounds. Therefore, early detection and effective intervention strategies aimed at students with these ND are crucial to improve their educational functioning and mitigate the negative consequences related to academic problems.
