High Prevalence of Dysgraphia in Elementary Through High School Students With ADHD and Autism

From Consensus Statement to Pills to Pixels: New Innovations in Attention-Deficit/Hyperactivity Disorder Care

Objectives: This review aims to present recent innovations and advancements in attention-deficit/hyperactivity disorder (ADHD) care, encompassing international consensus statement, new medication formulations, digital therapeutics, and neurostimulation devices. Methods: A comprehensive literature search of relevant articles published in the past five years was conducted, emphasizing the evidence base, efficacy, safety, and practical implications of these advancements. Results: The World Federation of ADHD Consensus Statement offers an updated diagnostic and treatment framework rooted in global scientific evidence. There are several newer ADHD medication formulations, including a nonstimulant (Viloxazine extended release) and the first transdermal amphetamine patch approved to treat ADHD. These options offer some unique benefits to personalize treatment based on symptom profile, lifestyle, preferences, and response. Digital tools offer additional means to restructure environments for individuals with ADHD, reducing impairment and reliance on others. In addition, digital therapeutics enhance access, affordability, personalization, and feasibility of ADHD care, complementing or augmenting existing interventions. Trigeminal nerve stimulation emerges as a well-tolerated nonpharmacological, device-based treatment for pediatric ADHD, with initial trials indicating effect sizes comparable to nonstimulant medications. Conclusions: These innovations in ADHD care represent clinically significant new treatment options and opportunities for personalized care. Health care professionals should integrate these developments into clinical practice, mindful of individual patient and family needs and preferences. Future research should assess long-term outcomes, cost-effectiveness, and acceptability of these innovations.

The Modularity of Dysgraphia

Research regarding dysgraphia, an impairment in writing, is attaining more attention in recent times. The existing studies on dysgraphia draw insights from cognitive, behavioural, neurological, and genetic fields of knowledge. However, these multiple studies on dysgraphia fail to illustrate how these cognitive, behavioural, neurological, and genetic systems interact and intersect in dysgraphia. Therefore, the studies could not offer a comprehensive understanding of dysgraphia. In order to fill this gap, the review attempts to study dysgraphia using the notion of modularity by accommodating insights from cognitive, behavioural, neurological, and genetic aspects of dysgraphia. Such a profound understanding could facilitate an early diagnosis and holistic intervention towards dysgraphia.

A systematic review of behavioral and neurobiological profiles associated with coexisting attention-deficit/hyperactivity disorder and developmental coordination disorder

Attention-deficit/hyperactivity disorder (ADHD) and developmental coordination disorder (DCD) co-occur in approximately 50% of cases. This study aimed to characterize the behavioral, cognitive, and neurobiological profiles of co-occurring ADHD and DCD diagnoses by mapping, synthesizing, and providing a critical appraisal of the existing literature. A systematic search was conducted across four databases (MEDLINE, PsycINFO, Embase, and Scopus) to identify studies comparing a coexisting ADHD+DCD diagnosis to ADHD and DCD alone. From 2353 screened articles, 15 behavioral and 10 neuroimaging studies were included. Collectively, these studies suggest that the comorbid ADHD+DCD presentation constitutes a more severe phenotype characterized by neurocognitive differences associated with both conditions. Despite sharing some common neural features, our findings support the separate etiology hypothesis indicating that neural network alterations in individuals with ADHD+DCD represent a unique neural pattern rather than a sum of ADHD and DCD characteristics. Considering the heterogeneity inherent to both ADHD and DCD, future studies should involve rigorous and comprehensive assessment procedures to delineate how different subtypes of each diagnosis relate to distinct performance characteristics.

Sluggish cognitive tempo: Association with neuropsychological test scores, motor incoordination, and dysgraphia in elementary school children

Research on the relationship between sluggish cognitive tempo (SCT) and scores on neuropsychological tests (such as those measuring processing speed and reaction time) is inconclusive, and the association between SCT and motor incoordination and dysgraphia has not been objectively investigated. Mothers of 413 elementary school children (6-12 years of age) rated their children on the Pediatric Behavior Scale (PBS), which yields psychological problem scores, including SCT. Children were administered an extensive battery of neuropsychological tests assessing processing and performance speed, working memory, immediate and delayed recall, sustained attention, response inhibition, cognitive flexibility, fine motor manipulative skill, verbal fluency and retrieval, set shifting, and interference control, as well as intelligence and reading and math achievement. Only three of the 19 correlations between SCT and neuropsychological scores were significant, and all involved graphomotor tests (two timed and one untimed). In regression analysis, the strongest independent predictor of SCT was the maternal PBS incoordination factor score, followed by ratings of autism, inattention, and depression. Neuropsychological test scores did not contribute significantly more to predicting SCT. Among the incoordination PBS factor items, clumsy and draws or writes poorly were significant SCT predictors. Our novel and unexpected findings showed that motor incoordination was a stronger correlate of SCT than other variables assessed in our study, including those previously linked with SCT. Future SCT research needs to include measures of incoordination and dysgraphia in order to replicate and expand upon the current findings. Our results suggest that SCT traits are not reliably measured by currently available neuropsychological tests.

Perspectives and Experiences of Autistic Multilingual Adults: A Qualitative Analysis

Background

The combined experience of autism and bilingualism is poorly understood, leading to poor support for autistic people in multilingual environments or those interested in languages. While most available studies focus on the language and cognitive profiles of autistic bilinguals, or on the experiences of parents, little is known about the lived experiences of autistic multilinguals.

Methods

To address this question, this study examined the impact of autism and multilingualism on the lives of 54 autistic multilingual adults who completed an online survey assessing the profiles of autistic bi- and multilinguals. We conducted a thematic analysis of responses to the survey's open-ended questions to explore motivations for learning languages and the perceived benefits of being both autistic and multilingual.

Results

There was a wide range of language profiles in the sample, with various levels of proficiency, ages of acquisition, and learning environments. Respondents felt that being autistic can both positively and negatively influence language learning. They reported various motivating factors for the acquisition of multiple languages, including social aspects and a predisposition for language learning. Respondents reported many benefits of multilingualism, such as educational, employment, or leisure opportunities; social skills and understanding of other people; self-confidence in their own abilities; and relationships with family, friends, and the worldwide autistic community.

Conclusions

Unlike previous work with autistic multilinguals involving case studies, the larger sample involved here offers valuable insight into the profiles and experiences of this overlooked population. Importantly, autistic people can experience numerous benefits from multilingualism. These findings will have implications for language education practices as well as for multilingual families and the practitioners who support them.

Lay summary

Why was this study done?: We wanted to understand what it feels like to be both autistic and multilingual, in a world where it is often assumed that both cannot go together. The combined experience of autism and bilingualism is poorly understood. This leads to poor support for autistic people in bilingual environments or for those interested in languages. Most studies available focus on the language and mental abilities of autistic bilinguals, or on the experiences of parents. However, very few studies focus on the lived experiences of autistic multilinguals themselves.What was the purpose of this study?: The purpose of this study was to understand the experiences of autistic multilingual adults. We focused on their learning motivations and the perceived benefits of being autistic and multilingual.What did the researchers do?: Fifty-four autistic multilingual adults completed an online questionnaire designed for autistic bi- and multilinguals. The questionnaire included questions about the respondents' language history and language profiles. There were also open-ended questions about the respondents' motivations for learning languages, and their general experience of being both autistic and multilingual. We analyzed and summarized the responses to these open-ended questions to understand the experience of autistic multilingual adults.What were the results of the study?: Our sample had a diverse range of language profiles and experiences. Respondents thought that autism could be both an advantage and a disadvantage for language learning. They reported a range of motivations for language learning, including a predisposition for language learning. They considered relationships as both a motivation to learn languages and a benefit of multilingualism. Respondents thought that being multilingual had brought them many opportunities for leisure, travels, education, and employment. They considered that being multilingual had improved their self-confidence. They also thought that being multilingual had increased their awareness and understanding of autism, allowing them to connect with the wider autistic population.What do these findings add to what was already known?: Previous research with autistic multilinguals involved only one or two participants. The larger group of autistic multilinguals involved in this study offers valuable insight into the lived experiences of this overlooked population.What are potential weaknesses in the study?: The online questionnaire was not originally designed to collect in-depth data on lived experiences. This means that the questions included very few prompts: respondents were able to discuss the aspects of their experience that were the most important to them. The absence of specific topics in the results does not mean that they are not experienced, but simply that the participants did not spontaneously mention them. Future research should build upon our findings and focus on specific topics, such as learning environments or opportunities.How will these findings help autistic adults now or in the future?: These findings will help autistic adults by highlighting the diversity and richness of their language profiles, abilities, and experiences. This will prompt families, educators, and practitioners to better support and include autistic people in multilingual environments or those interested in languages.

Relative Frequency of Psychiatric, Neurodevelopmental, and Somatic Symptoms as Reported by Mothers of Children with Autism Compared with ADHD and Typical Samples

No study has analyzed the relative occurrence of a broad range of symptoms reported by mothers of children with autism, ADHD-Combined, and ADHD-Inattentive and typical controls. Mothers rated 1436 children with autism, 1056 with ADHD without autism, and 186 controls, 2-17 years, on 41 internalizing, externalizing, neurodevelopmental, and somatic problems. Most children with autism had symptoms of ADHD, oppositional defiant disorder, disruptive mood dysregulation disorder, and expressive language disorder and almost half had dysgraphia and receptive language disorder. Symptom overlap between autism and ADHD-Combined was high. Clinicians specializing in autism and ADHD must have expertise in evaluating and treating these comorbidities identified as most problematic by mothers in order to relieve family concerns and develop treatment plans relevant to families.

Observing Visual Attention and Writing Behaviors During a Writing Assessment: Comparing Children with Autism Spectrum Disorder to Peers with Attention-Deficit/Hyperactivity Disorder and Typically Developing Peers

Children with autism spectrum disorder (ASD) demonstrate heterogeneous writing skills that are generally lower than their typically developing (TD) peers and similar to peers with attention difficulties like attention-deficit/hyperactivity disorder (ADHD). Recent evidence suggests children with ASD spend less time engaging in writing tasks compared to their peers, but previous studies have not examined engagement specifically within the writing task environment. This study used video observation data collected from 121 school-age children (60 children with ASD, 32 children with ADHD, and 29 TD children) to compare differences in visual attention and writing task behaviors and relationships between task behaviors and age, cognitive skills, and ASD and ADHD symptom severity. Findings indicated that groups mostly spent time looking at and writing on the draft, though this was lowest in the ASD group. No differences were found between the ASD and ADHD groups after accounting for task behavior durations as percentages of total used task time. Groups spent little time looking at their outlines and looking away from the task, with all groups spending relatively more time looking at the task picture. Time spent engaged with the draft showed a positive relationship with writing performance across groups, but a negative relationship between time spent looking at the task picture and writing performance only appeared for the ADHD group. The ASD and ADHD groups showed negative associations between draft engagement and ASD symptom severity but not ADHD symptom severity. Implications are discussed for understanding writing task engagement in research and instructional contexts. LAY SUMMARY: Children with autism spectrum disorder (ASD) demonstrate variable writing skills. Here, we examine how children with ASD engage during a writing task by using video observation data to compare their engagement to peers with and without attention difficulties. Findings indicate (a) lower draft engagement and similar task disengagement in children with ASD compared to their peers and (b) moderate-to-strong relationships between writing scores and ASD symptom severity with within-task engagement in children with ASD and their peers with attention difficulties.
