Updated European Consensus Statement on diagnosis and treatment of adult ADHD

Subclinical attention-deficit hyperactivity disorder symptoms and unhealthy lifestyle behaviours

BACKGROUND

Literature emphasises the importance of identifying and intervening in the adoption of unhealthy lifestyle behaviours (ULBs) during adolescence at an early stage, to mitigate their long-term detrimental effects. Among the possible associated factors contributing to ULBs, attention-deficit hyperactivity disorder (ADHD) has been shown to play an important role. However, little is known about ADHD subclinical manifestations.

AIMS

The present study aimed to bridge the gap in the literature and shed light on the relationship between subclinical ADHD and early adoption of ULBs during adolescence. Through a clinimetric approach, prevalence of ULBs, severity of ADHD symptoms and psychosocial factors (i.e. allostatic overload, abnormal illness behaviour, quality of life, psychological well-being) were investigated among adolescents. The associations between different degrees of ADHD, ULBs and psychosocial factors were also explored.

METHOD

This multicentre cross-sectional study involved 440 adolescents (54.5% females; mean age 14.21 years) from six upper secondary schools. Participants completed self-report questionnaires on sociodemographic characteristics, ULBs, ADHD symptoms and psychosocial factors.

RESULTS

The most common ULBs were energy drinks/alcohol consumption and problematic smartphone use. Of the sample, 22% showed subclinical ADHD and 20.2% showed clinical ADHD. The subclinical ADHD group showed several ULBs (i.e. altered mindful eating, impaired quality of sleep, problematic technology use) and psychosocial factors, akin to those of ADHD group and different from peers without ADHD symptoms.

CONCLUSIONS

Since subclinical ADHD manifestation is associated with ULBs, similarly to clinical ADHD, identifying subthreshold symptoms during adolescence is crucial, as it could improve health-related outcomes in adulthood across different domains.

Absent or Hidden? Hyperactivity in Females With ADHD

OBJECTIVE

This study aimed to objectively assess signs of hyperactivity in adults suspected of having ADHD, addressing potential sex bias in diagnosis.

METHODS

About 13,179 (49% female) adults with an average age of 33 years with ADHD and 1,910 (41% female) adults with an average age of 36 years without ADHD were included. Motor activity was measured using the Quantified Behavioral Test, analyzing "provoked," and "basal" activity. Sex by group differences were analyzed using analysis of variance.

RESULTS

Results showed significant ADHD effects on the basal and provoked activity measures, while sex effects were only notable for provoked activity. Males, irrespective of diagnosis, exhibited higher provoked activity than females, while both sexes with ADHD displayed approximately twice the basal activity and about three times the provoked activity compared to their respective sex controls.

CONCLUSION

These findings suggest that females with ADHD suffer equally from hyperactivity compared to males, challenging the notion of a sex-dependent presentation of hyperactivity. This may lead to more accurate and timely diagnoses, reducing ADHD-related burdens and comorbidities in females.

Attention-deficit/hyperactivity disorder in adolescent and adult candidates for metabolic and bariatric surgery: A systematic review and meta-analysis

AIMS

Attention-deficit with hyperactivity disorder (ADHD) is associated with obesity and impacts the outcome of metabolic and bariatric surgery (MBS). This study aimed at calculating the prevalence in candidates for MBS, which is yet unclear.

METHODS

We conducted a systematic review and meta-analysis, searching three databases from their respective inception to December 2022 for studies reporting the prevalence of ADHD in adolescents and adults assessed before undergoing MBS. The protocol was registered in PROSPERO (CRD42022384914). We adhered to Meta-analysis of Observational Studies in Epidemiology (MOOSE) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines; the quality of studies was assessed with the JBI Critical Appraisal checklist. Random-effect meta-analyses were performed; confidence intervals were computed with a binomial exact method, and the pooled estimate was calculated after double arcsine transformation.

FINDINGS

Fourteen studies (24,455 adults) and three studies (299 adolescents) were selected. The quality of studies was moderate to poor; meta-analyses were performed on subgroups according to the case definition used. The prevalence is 8.94% and 9.90% in adults, and 28.73% in adolescents.

CONCLUSIONS

ADHD is three times more frequent in adults and six times more frequent in adolescents than in the general population. Recommendations are provided to improve the quality of future studies and obtain more reliable estimates of prevalence.

Feasibility of the Understanding and Managing Adult ADHD Programme: open-access online group psychoeducation and acceptance and commitment therapy for adults with attention-deficit hyperactivity disorder

BACKGROUND

Psychoeducational interventions are a critical aspect of supporting adults with attention-deficit hyperactivity disorder (ADHD). The Understanding and Managing Adult ADHD Programme (UMAAP) is a six-session, group-based webinar intervention that incorporates psychoeducation with acceptance and commitment therapy. UMAAP relies on self-referrals and is facilitated by a charity, to promote accessibility.

AIMS

The present study aimed to evaluate the feasibility of UMAAP and explore preliminary effectiveness.

METHOD

Adults with formally diagnosed or self-identified ADHD (n = 257) participated in an uncontrolled pre-post design. Feasibility was indicated by attendance, confidence in completing the home practice and satisfaction. Quality of life, psychological flexibility, self-acceptance and knowledge of ADHD were assessed at baseline, 1 week post-intervention and 3 months later, to explore preliminary effectiveness.

RESULTS

Feasibility was demonstrated by the high attendance ratings and satisfaction with the intervention, although there was only moderate confidence in the ability to complete the home practices. Quality of life (mean increase 9.69, 95% CI 7.57-11.80), self-acceptance (mean increase 0.19, 95% CI 0.10-0.28) and knowledge of ADHD (mean increase 1.55, 95% CI 1.23-1.82) were significantly improved post-intervention. The effects were maintained at the 3-month follow-up. Psychological flexibility did not significantly change immediately post-intervention, but increased significantly at the 3-month follow-up (mean increase 0.42, 95% CI 0.26-0.58).

CONCLUSIONS

Overall, UMAAP is a feasible intervention for adults with ADHD. Findings highlighted the feasibility of delivering psychological interventions online in group settings, to increase access to support for adults with ADHD.

Exploring the associations between symptom severity, metacognition, problematic social media use and cyberbullying in treatment naïve adolescents with Attention Deficit and Hyperactivity Disorder

This study investigates the relationship between ADHD symptom severity, metacognition, problematic social media use, and cyberbullying/cybervictimization in treatment-naïve adolescents. Understanding these relationships is vital for enhancing ADHD intervention strategies. Using a cross-sectional design, 97 adolescents meeting DSM-5 criteria for ADHD without any comorbidity and 97 healthy controls were assessed. Measures included the Metacognitions Questionnaire for Children, Social Media Disorder Scale, Revised Cyberbullying Inventory-II, and Revised Conners' Parent Rating Scale-Short. The comparisons were performed with independent samples' t tests and the associations were estimated by using Pearson's bivariate correlations and multiple regression analyses. Results revealed that adolescents with ADHD exhibited higher levels of dysfunctional metacognitions, problematic social media use, cyberbullying, and cybervictimization compared to controls. Regression analysis showed significant positive associations between ADHD symptoms, specific metacognitions (e.g., positive meta-worry, cognitive monitoring), and problematic social media use. This study, the first of its kind among treatment-naïve ADHD adolescents, provides valuable insights into the relationship between ADHD symptoms and particular metacognitions (i.e. positive meta-worry, cognitive monitoring) and problematic social media use. These findings contribute to a deeper understanding of ADHD in adolescence and may inform the development of targeted prevention and treatment strategies, particularly relevant given adolescents' susceptibility to social media's influence and their potential for cognitive flexibility in rehabilitation contexts.

Having Reliable Support: A Prerequisite to Promote Sexual and Reproductive Health in Young Women with ADHD

Living with attention deficit hyperactivity disorder (ADHD) may influence sexual behaviors and intimate relationships in young women, resulting in a higher risk of unwanted pregnancy, sexual victimization, and sexual dysfunction. To develop adequate support, the study aimed to describe conceptions of how to promote sexual and reproductive health (SRH) in young women with ADHD. A secondary analysis using phenomenography was performed on qualitative interview data exploring variations of support. The study involved 15 young women with ADHD, aged 15-29 years, and 16 health care professionals, with various professions, working in the fields of gynecology, youth health, and psychiatry. Having reliable support was conceptualized as fundamental for promoting SRH. Access to information concerning SRH and living with ADHD as well as early support from health care contributed to a reliable support enabling self-knowledge and management of sexual relationships. Trustful relationships in health care were perceived as important because of previous experiences of feeling misunderstood and criticized in life, making them feel comfortable discussing SRH. Clinical encounters with a clear structure were further perceived to make information more accessible and clinics that provided appropriate organizational conditions and collaborated with other clinics were described to enhance the availability of support. This study reveals the need for clinics to provide conditions that ensure SRH support is available, accessible, and free of stigmatization. Early intervention programs for young women with ADHD may be considered, offering guidance on SRH issues in both psychiatric and sexual health clinics.

Investigating the Impact of Nutrition and Oxidative Stress on Attention Deficit Hyperactivity Disorder

Background/Objectives: Attention deficit hyperactivity disorder (ADHD) is the most common childhood-onset neurodevelopmental disorder, characterized by difficulty maintaining attention, impulsivity, and hyperactivity. While the cause of this disorder is still unclear, recent studies have stated that heredity is important in the development of ADHD. This is linked to a few comorbidities, including depression, criminal behavior, and anxiety. Although genetic factors influence ADHD symptoms, there are also non-genetic factors, one of which is oxidative stress (OS), which plays a role in the pathogenesis and symptoms of ADHD. This review aims to explore the role of OS in ADHD and its connection to antioxidant enzyme levels, as well as the gut-brain axis (GBA), focusing on diet and its influence on ADHD symptoms, particularly in adults with comorbid conditions. Methods: The literature search included the main available databases (e.g., Science Direct, PubMed, and Google Scholar). Articles in the English language were taken into consideration and our screening was conducted based on several words such as "ADHD", "oxidative stress", "diet", "gut-brain axis", and "gut microbiota." The review focused on studies examining the link between oxidative stress and ADHD, the role of the gut-brain axis, and the potential impact of dietary interventions. Results: Oxidative stress plays a critical role in the development and manifestation of ADHD symptoms. Studies have shown that individuals with ADHD exhibit reduced levels of key antioxidant enzymes, including glutathione peroxidase (GPx), catalase (CAT), and superoxide dismutase (SOD), as well as a diminished total antioxidant status (TOS) compared to healthy controls. Additionally, there is evidence of a close bidirectional interaction between the nervous system and gut microbiota, mediated by the gut-brain axis. This relationship suggests that dietary interventions targeting gut health may influence ADHD symptoms and related comorbidities. Conclusions: Oxidative stress and the gut-brain axis are key factors in the pathogenesis of ADHD, particularly in adults with comorbid conditions. A better understanding of these mechanisms could lead to more targeted treatments, including dietary interventions, to mitigate ADHD symptoms. Further research is required to explore the therapeutic potential of modulating oxidative stress and gut microbiota in the management of ADHD.

ADHD Assessment and Treatment Services in a Sample of U.S. Colleges and Universities

OBJECTIVE

Up to 2 million college students in the United States have been diagnosed as having attention-deficit hyperactivity disorder (ADHD), a condition associated with negative academic, social, and psychiatric outcomes. The authors investigated the online availability and content of policies governing ADHD services at college clinics.

METHODS

Using a stratified sample of 200 colleges and universities, the authors reviewed clinic websites and invited clinical staff to participate in a survey. They weighted percentages to account for oversampling and used regression modeling to examine associations with policy availability.

RESULTS

Only 70 institutions (32%, weighted percentage) provided information about ADHD services online. Institutions with <1,000 students had significantly lower odds of providing information online (adjusted odds ratio [AOR]=0.04, 95% CI=0.01-0.26), as did institutions that accepted >67% of applicants (AOR=0.18, 95% CI=0.07-0.48). After merging data from the Web review and survey, the authors noted that 14% (N=11 of 75 institutions with data available for this variable) facilitated neuropsychological assessments on campus, 49% (N=33 of 72) did not allow stimulant medications to be prescribed, 73% (N=43 of 61) did not offer clinical evaluations for ADHD, and 89% (N=32 of 35) required a neuropsychological assessment to receive prescription stimulants.

CONCLUSIONS

Information about the assessment and management of ADHD is rarely available online, and ADHD services on U.S. college campuses appear to be limited.

Multimodal treatment of attention-deficit/hyperactivity disorder and comorbid symptoms in an ultra football fan: A case report from Switzerland

This case report describes the therapeutic trajectory of a 47-year-old male ultra football fan from Switzerland, who was diagnosed and treated for attention-deficit/hyperactivity disorder, together with comorbid alcohol misuse and insomnia. Prior to this episode of care, the patient exhibited symptoms of impulsivity and inattention and persistent patterns of harmful alcohol consumption, recurrently participating in football-related violence. A multimodal approach involving psychotherapy and psychopharmacology yielded notable improvements in symptom management. To date, the patient has shown improved psychosocial functioning, reporting a significant reduction in alcohol use and the cessation of all aggressive acts. Consequently, this case provides insights into the relationship between attention-deficit/hyperactivity disorder and football-related violence, underlining the potential for tailored mental health interventions to enhance overall quality of life.

Support for primary care prescribing for adult ADHD in England: national survey

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, for which there are effective pharmacological treatments that improve symptoms and reduce complications. Guidelines published by the National Institute for Health and Care Excellence recommend that primary care practitioners prescribe medication for adult ADHD under shared-care agreements with Adult Mental Health Services (AMHS). However, provision remains uneven, with some practitioners reporting a lack of support.

AIM

This study aimed to describe elements of support, and their availability/use, in primary care prescribing for adult ADHD medication in England to improve access for this underserved population and inform service improvement.

DESIGN AND SETTING

Cross-sectional surveys were used to elicit data from commissioners, health professionals (HPs), and people with lived experience of ADHD (LE) across England about elements supporting pharmacological treatment of ADHD in primary care.

METHOD

Three interlinked cross-sectional surveys were used to ask every integrated care board in England (commissioners), along with convenience samples of HPs and LEs, about prescribing rates, AMHS availability, wait times, and shared-care agreement protocols/policies for the pharmacological treatment of ADHD in primary care. Descriptive analyses, percentages, and confidence intervals were used to summarise responses by stakeholder group. Variations in reported provision and practice were explored and displayed visually using mapping software.

RESULTS

Data from 782 responders (42 commissioners, 331 HPs, 409 LEs) revealed differences in reported provision by stakeholder group, including for prescribing (95% of HPs versus 64% of LEs). In all, >40% of responders reported extended AMHS wait times of ≥2 years. There was some variability by NHS region - for example, London had the lowest reported extended wait time (25%), while East of England had the highest (55%).

CONCLUSION

Elements supporting appropriate shared-care prescribing of ADHD medication via primary care are not universally available in England. Coordinated approaches are needed to address these gaps.

Effect of ginseng and ginsenosides on attention deficit hyperactivity disorder: A systematic review

Attention deficit hyperactivity disorder (ADHD) is a rapidly increasing neurodevelopmental disorder but currently available treatments are associated with abuse risk, side effects, and incomplete symptom relief. There is growing interest in exploring complementary options, and ginseng has gained attention for its therapeutic potential. This systematic review aimed to assess current evidence on the efficacy of ginseng and its active components, ginsenosides, for ADHD. Eligible studies were identified through searches of PubMed, Embase, Cochrane Library, and Web of Science, up to June 2023. The inclusion criteria included both human and animal studies that investigated the effects of ginseng or ginsenosides on ADHD. The risk of bias was assessed according to study type. Six human studies and three animal studies met the inclusion criteria. The results suggest that ginseng and ginsenosides may have beneficial effects on ADHD symptoms, particularly inattention, through dopaminergic/norepinephrinergicmodulation and BDNF/TrkB signaling. Ginseng and ginsenosides have promising potential for ADHD treatment. Due to limitations in evidence quality, such as the risk of bias and variability in study designs, larger controlled studies are essential. Integrating ginseng into ADHD management may have valuable implications for individuals seeking well-tolerated alternatives or adjunctive therapies.

Coping with emotional dysregulation among young adults with ADHD: A mixed-method study of self-awareness and strategies in daily life

BACKGROUND

Emotional dysregulation (ED) impacts functional outcomes among individuals with attention-deficit hyperactivity disorder (ADHD). Self-awareness and strategies may enhance coping with ED yet are rarely studied in ADHD.

OBJECTIVES

To explore ED-related self-awareness and strategies in daily life of adults with ADHD, and to examine the interrelations between them and their association with symptoms.

METHODS

Sixty young adults with ADHD participated in a mixed-method study. At baseline, self-awareness and strategies were assessed using the Self-Regulation Skills Interview (SRSI); ADHD symptoms were self-rated using the ASRS symptom checklist. Then, symptoms were rated over 5-days using ecological momentary assessment (EMA).

RESULTS

Significant challenges in self-awareness and strategies were demonstrated quantitatively and qualitatively. Awareness of ED was associated with variability of ADHD symptoms on EMA yet not with symptom severity. Qualitative content analysis revealed a range of self-awareness levels, which were related to noticing ED-related cues and understanding contextual factors predictive of ED. Self-awareness and strategies were significantly associated. Strategies varied regarding effort, individual preference and temporality.

CONCLUSIONS

Variability of ADHD symptoms was negatively associated with self-awareness of ED. Strategy selection in daily-life among adults with ADHD may be affected by self-awareness and by a possible trade-off between short-term effort and long-term effectiveness.

Childhood ADHD and subthreshold symptoms are associated with cognitive functioning at age 40-a cohort study on perinatal birth risks

Introduction

In this prospective cohort study over 40 years we investigated the effect of childhood attention-deficit/hyperactivity disorder (ADHD) and subthreshold ADHD on cognitive performance in adulthood.

Methods

The cohort comprised individuals with mild perinatal risks. Childhood ADHD group (cADHD, n = 39) was compared to a group with subthreshold childhood attention or hyperactivity symptoms (cAP; n = 79), a group with similar perinatal risks but no ADHD symptoms (n = 255), and to controls without ADHD symptoms or perinatal risks (n = 69). The groups were assessed with multiple neuropsychological measures in domains of verbal reasoning, perceptual skills, memory, working memory, attention, executive functions, and speed. Group-level differences and frequencies of deficient functioning were analyzed.

Results

Overall, the groups' performance differed in all cognitive domains at age 40. Verbal reasoning, perceptual skills, memory, and speed had the largest effect sizes (0.51-0.62). The cADHD group's performance was lower than the other groups' on 13 out of 21 measures. The cAP group performed poorer than controls on five measures. In the cADHD group, 23% had three or more deficient cognitive domains, compared to 4-6% in the other groups.

Discussion

Childhood ADHD is associated with impaired cognitive functioning in adulthood on several cognitive domains whereas childhood subthreshold ADHD is linked to fewer cognitive deficits. Task complexity was linked to poorer performance within the ADHD group. Our results add to the scarce longitudinal evidence of cognitive outcomes related to childhood ADHD and subthreshold symptoms.

Predicting emotional consequences of disorganization among adults with neurodevelopmental disorders: a structural equation model

PURPOSE

Previous studies exhibited differences in sensory processing, motor coordination, metacognitive executive functions (EF-MI), and sleep quality among adults with neurodevelopmental disorders (NDD). This study aims to find relationships between those abilities and organization-in-time, focusing on emotional responses after decreased organization abilities.

MATERIALS AND METHODS

This is a secondary data analysis of a larger sample from three previous studies conducted in one laboratory. Data were collected from 290 adults; 149 with NDD and 141 sex- and age- (20-50 years) matched controls completed the Adolescent/Adult Sensory Profile, Adult Developmental Coordination Disorder, Adults Behavioral Rating Inventory of Executive Functions, Mini Sleep, and Time Organization and Participation questionnaires. Structural equation model (SEM) analysed relationships and variable prediction.

RESULTS

Significant between-group differences were found for all variables; SEM indicated similar paths in both groups. Sensory processing affected EF-MI and sleep quality and significantly correlated with motor coordination, affecting EF-MI; EF-MI affected organization-in-time. Sleep quality significantly affected organization-in-time, affecting emotional responses.

CONCLUSIONS

Sensory, motor, EF, and sleep differences were associated with decreased organization-in-time abilities of adults with NDD, adversely affecting their emotional well-being. Early detection of such differences and targeted interventions may improve daily functioning and life quality and prevent negative emotional implications.

Quantification of ADHD medication in biological fluids of pregnant and breastfeeding women with liquid chromatography: a comprehensive review

Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that has long been considered a concern only in the pediatric population. However, symptoms often sustain into adulthood and may require medication. For women with ADHD, this also means dealing with the disorder during the reproductive period. Medication safety during pregnancy and breastfeeding is a critical concern, and the potential transfer of ADHD medication to infants remains a topic of scientific interest. The quantification of ADHD medications in both maternal blood and breast milk are vital for understanding their pharmacokinetics and potential exposure risks for (nursing) infants. This review aims (1) to compile and critically assess existing research on the transfer of ADHD medications into breast milk and the potential implications for nursing infants and (2) to provide a comprehensive overview and discussion of the literature regarding the quantification of methylphenidate, amphetamine, atomoxetine, viloxazine, guanfacine, clonidine and bupropion in the blood, urine, oral fluid, and breast milk with liquid chromatography. A literature search was conducted using PubMed, Scopus, and Web of Science, to identify relevant articles published from January 2014 up to December 2023. We illustrate the lack of methods to simultaneously monitor multiple ADHD medications as well as the lack of developed methods for breast milk. Finally, we highlight the need for continued research to refine our understanding of medication transfer into breast milk and potential risks, and to develop clinical guidelines to support mothers with ADHD in making informed choices regarding medication use during pregnancy and lactation.

Machine learning-enabled detection of attention-deficit/hyperactivity disorder with multimodal physiological data: a case-control study

BACKGROUND

Attention-Deficit/Hyperactivity Disorder (ADHD) is a multifaceted neurodevelopmental psychiatric condition that typically emerges during childhood but often persists into adulthood, significantly impacting individuals' functioning, relationships, productivity, and overall quality of life. However, the current diagnostic process exhibits limitations that can significantly affect its overall effectiveness. Notably, its face-to-face and time-consuming nature, coupled with the reliance on subjective recall of historical information and clinician subjectivity, stand out as key challenges. To address these limitations, objective measures such as neuropsychological evaluations, imaging techniques and physiological monitoring of the Autonomic Nervous System functioning, have been explored.

METHODS

The main aim of this study was to investigate whether physiological data (i.e., Electrodermal Activity, Heart Rate Variability, and Skin Temperature) can serve as meaningful indicators of ADHD, evaluating its utility in distinguishing adult ADHD patients. This observational, case-control study included a total of 76 adult participants (32 ADHD patients and 44 healthy controls) who underwent a series of Stroop tests, while their physiological data was passively collected using a multi-sensor wearable device. Univariate feature analysis was employed to identify the tests that triggered significant signal responses, while the Informative k-Nearest Neighbors (KNN) algorithm was used to filter out less informative data points. Finally, a machine-learning decision pipeline incorporating various classification algorithms, including Logistic Regression, KNN, Random Forests, and Support Vector Machines (SVM), was utilized for ADHD patient detection.

RESULTS

Results indicate that the SVM-based model yielded the optimal performance, achieving 81.6% accuracy, maintaining a balance between the experimental and control groups, with sensitivity and specificity of 81.4% and 81.9%, respectively. Additionally, integration of data from all physiological signals yielded the best results, suggesting that each modality captures unique aspects of ADHD.

CONCLUSIONS

This study underscores the potential of physiological signals as valuable diagnostic indicators of adult ADHD. For the first time, to the best of our knowledge, our findings demonstrate that multimodal physiological data collected via wearable devices can complement traditional diagnostic approaches. Further research is warranted to explore the clinical applications and long-term implications of utilizing physiological markers in ADHD diagnosis and management.

Probation practice and attention-deficit hyperactivity disorder

RATIONALE

Twenty-one Community Rehabilitation Companies were set up following the division of the National Probation Services during 'Transforming Rehabilitation' in England and Wales, under a 2013 Ministry of Justice initiative. Reunification commenced in 2018. A study completed prior to these changes suggested that probation officers had had little training in recognising attention-deficit hyperactivity disorder (ADHD) and may have been underestimating its prevalence among their clientele. Given the substantial changes in probation staffing and organisation since 2018, a new study seems warranted.

AIMS

The aim of the study was to understand experiences of people under a community sentence who reported having ADHD and of probation staff working with them.

METHODS

Using a qualitative research design, one-to-one semi-structured interviews were conducted with client facing probation staff recruited from one Community Rehabilitation Company. Service users undertaking a community sentence who had been diagnosed with or self-identified as having ADHD were then identified and recruited by these staff; those who consented were also interviewed. Transcripts were analysed using a thematic analytic approach.

RESULTS

Thirteen probation staff and six male offenders under community sentences, agreed to participate and completed interviews. The overarching themes emerging from the two groups were similar, both reflecting on descriptions of ADHD; treatment of ADHD; experiences of having or working with ADHD in the wider community and in the criminal justice system specifically and visions of future support needs tied to the order. In addition, probation officers specifically raised the matter of payment by results. Both service users and probation staff identified gaps in knowledge, experience and services, but areas of good practice were also identified.

CONCLUSION

The findings highlight the continuing under-acknowledgement of tailored clinical support for people serving a community sentence who have ADHD together with a lack of support and training about ADHD for probation staff. Return to the national organisation of probation services and recognition of need for a range of relevant skills offers a great opportunity for re-evaluating supervision and management of offenders under community sentences who have ADHD. These findings provide the basis for a template for developing knowledge and support provision for probation staff to recognise ADHD, or its likelihood, and their capacity to follow through with appropriately informed personalised supervision plans and access to specialist service advice and support.

Current nonstimulant medications for adults with attention-deficit/hyperactivity disorder

INTRODUCTION

Stimulants, including methylphenidate and amphetamines, are the first-line pharmacological treatment of ADHD in adults. However, in patients who do not respond or poorly tolerate stimulants, non-stimulant medications are usually recommended.

AREAS COVERED

The authors provide a narrative review of the literature on non-stimulant treatments for adult ADHD, including controlled and observational clinical studies conducted on adult samples. Atomoxetine has been extensively studied and showed significant efficacy in treating adult ADHD. Issues related to dosing, treatment duration, safety, and use in the case of psychiatric comorbidity are summarized. Among other compounds indicated for ADHD in adults, antidepressants sharing at least a noradrenergic or dopaminergic component, including tricyclic compounds, bupropion, and viloxazine, have shown demonstratable efficacy. Evidence is also available for antihypertensives, particularly guanfacine, as well as memantine, metadoxine, and mood stabilizers, while negative findings have emerged for galantamine, antipsychotics, and cannabinoids.

EXPERT OPINION

While according to clinical guidelines, atomoxetine may serve as the only second-line option in adults with ADHD, several other nonstimulant compounds may be effectively used in order to personalize treatment based on comorbid conditions and ADHD features. Nevertheless, further research is needed to identify and test more personalized treatment strategies for adults with ADHD.

Somatic burden of attention-deficit/hyperactivity disorder across the lifecourse

OBJECTIVE

A thorough and comprehensive knowledge base on the extent of comorbidity of attention-deficit/hyperactivity disorder (ADHD) and somatic conditions is needed.

METHOD

We compared the prevalence of a wide range of somatic conditions in individuals with and without ADHD and described sex and lifecourse differences. Individuals with an ADHD diagnosis (N = 87,394) and age and sex-matched individuals without an ADHD diagnosis were identified from a large health claims dataset representative of the general German population, including both primary and specialized care (N = 4.874,754). Results were provided for the full sample as well as stratified for sex and age (<12 years, 13-17 years, 18-29 years, 30-59 years, ≥60 years).

RESULTS

The results showed that ADHD is associated with a wide variety of somatic conditions across the entire lifecourse. Specifically neurological disorders such as Parkison's disease (odds ratio [OR]: 5.21) and dementia (OR: 2.23), sleep-related disorders (OR: 2.38) and autoimmune disorders affecting the musculoskeletal, digestive, and endocrine system (fibromyalgia OR: 3.33; lupus OR: 2.17) are strongly and significantly associated with ADHD. Additionally, ADHD is associated with higher occurrence of common acute diseases typically treated by the general practitioner, hinting at an overall general lower health status. Sex differences in somatic comorbidity were not prominent. Age differences, in contrast, stood out: in particular endocrine, cardiovascular, and neurological disorders had an early onset in individuals with compared to individuals without ADHD.

CONCLUSION

This research underlines the high burden of disease due to somatic conditions among individuals with ADHD. The findings indicate the need for preventive measures to reduce comorbidity.

Parental ADHD knowledge and medical visit status of school-aged children in Shanghai

INTRODUCTION

The diagnosis and care of children and adolescents with neurodevelopmental disorders presents a public health crisis in China. Attention deficit hyperactivity disorder (ADHD) is one of the most frequent conditions. Many Chinese children and adolescents with ADHD are underdiagnosed and undertreated. This study aimed to evaluate the awareness and attitude parents have about ADHD, and investigated potential factors influencing ADHD medical visit status among school-aged children in Shanghai.

METHODS

A random cluster sampling method was used, and four primary schools in Shanghai were selected. One class was randomly selected from each grade, including students and their parents. Parents completed the Swanson, Nolan, and Pelham Version IV Questionnaire (SNAP-IV) parent form and questionnaire concerning ADHD awareness, knowledge, attitude and status of ADHD medical visit. Descriptive analysis was conducted on the overall results and logistic regression analysis was performed to explore the influencing factors of ADHD medical visit.

RESULTS

We received 617 valid questionnaires. There were 313 boys (50.7%) and 304 girls (49.2%), with a median age of 8 years old (p25 = 7, p75 = 9). 42.4% parents believed they had some knowledge about ADHD, and 73.5% of them thought ADHD was a neurologically based disorder or neurological condition by nature. Parental ADHD information came from the following sources: Internet/TV (n = 458, 74.2%), families/friends (n = 267, 43.2%), print publication (n = 208, 33.7%), psychiatrists/pediatricians (n = 192, 31.1%), schools/teachers (n = 186, 30.1%) and other ADHD patients (n = 48, 7.7%). When children had ADHD-like behaviors, most parents (61.5%) educated children to behave themselves, 59.1% parents tried to get help from psychiatrists/pediatricians, 55.5% of them would ask psychologist for help. In terms of the ADHD prevalence, the SNAP-IV positive screen rate was 4.3% (n = 27). Only 33.3% (9/27) of parents went to the hospital for consultation and treatment. Multivariate logistic regression model showed that parental knowledge about ADHD (OR = 13.67, 95%CI: 1.72, 144.39, P = 0.01) was significantly correlated with the medical visit. Parents with sufficient knowledge of ADHD tend to visit hospital for help when they thought their children had ADHD related symptoms.

CONCLUSIONS

The majority of parents accepted ADHD as a neurodevelopmental disorder by nature, but some parents still had certain misunderstandings about ADHD. The main source of information for parents to obtain information about ADHD was through the TV/Internet. Parents' perceptions and knowledge were key to whether children received appropriate treatment for their ADHD. However, medical visits to address ADHD among school-aged children were still lower than expected. Government and healthcare institutes should work to improve ADHD public awareness and to help patients and their families gain access to mental health resources.

The Role of Diet and the Gut Microbiota in Reactive Aggression and Adult ADHD-An Exploratory Analysis

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental condition, of-ten persistent into adulthood and accompanied by reactive aggression. Associations of diet and the gut-microbiome with ADHD as well as emotional behaviors suggest potential clinical rele-vance of both. However, studies on diet and the gut-microbiome in human reactive aggression are lacking, and should investigate the interaction between diet and the gut-microbiome leading to behavioral changes to assess their potential clinical relevance. In this study, we investigated the interaction of diet and gut-microbiota with adult ADHD and reactive aggression in 77 adults with ADHD and 76 neurotypical individuals. We studied the relationships of ADHD and reactive ag-gression with dietary patterns, bacterial community and taxonomic differences of 16S-sequenced fecal microbiome samples, and potential mediating effects of bacterial genus abundance on signifi-cant diet-behavior associations. The key findings include: (1) An association of high-energy intake with reactive aggeression scores (pFDR = 4.01 × 10-02); (2) Significant associations of several genera with either reactive aggression or ADHD diagnosis with no overlap; and (3) No significant mediation effects of the selected genera on the association of reactive aggression with the high-energy diet. Our results suggest that diet and the microbiome are linked to reactive aggression and/or ADHD individually, and highlight the need to further study the way diet and the gut-microbiome inter-act.

Medical education: Accommodating students with ADHD

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects a significant number of medical students worldwide. It is poorly recognised by educators, and therefore inadequately accommodated for in educational strategies. In order to investigate this further, a literature review and pilot survey were conducted. Health educators employed by The University of Newcastle, Australia, completed a short online survey, which focused on their understanding of, and ability to recognise and adapt teaching strategies for students with ADHD. The results of the survey informed the development of a resource that provided evidence-based strategies for supporting the learning of tertiary students with ADHD. In addition, the results of this pilot study may form the basis for further research in this domain. Given the prevalence and potential impact of ADHD on higher education, it is important to gain deeper insight into how medical educators can best engage and support students with ADHD. This knowledge may potentially reduce the negative impacts of this neurodiversity on students and support their learning and well-being throughout their medical career. Ultimately this may help doctors to achieve their full potential, especially in clinical decision-making.

"I wish it wasn't all on me": women's experiences living with a partner with ADHD

PURPOSE

Grounded in the socio-ecological model of health, this study aims to understand the broader impact of adult attention deficit hyperactivity disorder (ADHD) on the family system. With a notable gap in knowledge concerning the impact of adult ADHD on spouses' well-being, this research explores the lived experiences of women in relationships with partners diagnosed with ADHD.

MATERIAL AND METHODS

Using a descriptive qualitative phenomenological approach, we conducted semi-structured interviews with thirteen women without ADHD, to gain insights into their experiences.

RESULTS

Three main themes were identified- ADHD in Everyday Life, Burden Experience, and Women's Coping Strategies for managing ADHD within relationships. The findings suggest that partners' ADHD symptoms involve a burden on women. In response, women developed coping strategies such as learning about ADHD, setting limits, and cultivating partnership by creating bridges to compensate for ADHD-related barriers.

CONCLUSIONS

This study highlights the substantial burden experienced by women in a relationship with partners diagnosed with ADHD, suggesting they should be recognized as caregivers and a potentially vulnerable group at risk. However, the homogeneous nature of our sample, focusing on white, heterosexual women, underlines the need for further research to better understand the impact of adult ADHD on diverse partners' functioning and health, as well as pathways to support them.

"I Found Comfort in Exercising": Exploring Experiences With Exercise for Adults With Attention-Deficit/Hyperactivity Disorder

Little is known about how adults with attention-deficit/hyperactivity disorder (ADHD) experience exercise, resulting in a lack of recommendations for supporting this population. We aimed to explore how adults with ADHD experience exercise as a management tool before and after diagnosis and how and why individuals experience issues related to exercise dependence. Fifteen active adults with a diagnosis of ADHD participated in semistructured interviews. Three overarching themes were identified: (a) exercise as a necessity for ADHD, reflecting the need to exercise before a formal ADHD diagnosis, and use of exercise as a management tool postdiagnosis; (b) goals and achievements to live by, reflecting how exercise patterns revolved around a need to make progress toward targets; and (c) activity or exercise: a roller coaster journey, covering the ups and downs of exercise journeys. This article highlights the importance of exercise for adults to manage ADHD and how this can be encouraged and supported.

Evaluation of Problematic Video Game Use in Adolescents with ADHD and without ADHD: New Evidence and Recommendations

Video game addiction among adolescents, particularly those with ADHD, is a significant concern. To gather more insights into video game usage patterns in this population, we investigated levels of potentially problematic use, passion, motivations, and emotional/behavioral symptoms in adolescents with and without ADHD. Our cross-sectional, multicenter study involved 2513 subjects (Age M = 15.07; SD = 2.82) from 24 schools in Galicia (Spain), including 158 (6.3%) diagnosed with ADHD. We employed an ad hoc questionnaire covering sociodemographic data and ADHD diagnosis, the Questionnaire of Experiences Associated with Video Games (CERV), the scale of passion for video games, reasons for playing video games Questionaire (VMQ), and emotional/behavioral problems assessment (SDQ). Results indicated heightened vulnerability in adolescents with ADHD, manifesting in longer usage durations and higher problematic use scores. Interestingly, ADHD medication did not affect internet gaming disorder development. Motivations for gaming differed between groups, with the ADHD cohort showing distinctions in cognitive development, coping, and violent reward. Additionally, the ADHD group exhibited greater emotional/behavioral symptoms, hyperactivity, and reduced prosocial behavior.

"It was very nice to be in a room where everyone had ADD-that's kind of VIP": Exploring clients' perceptions of group CBT for ADHD inattentive presentation

OBJECTIVES

This qualitative study explored the perceptions of adult clients participating in a new psychological treatment for attention-deficit/hyperactivity disorder inattentive presentation (ADHD-I, also called "attention deficit disorder", ADD). The study aimed to explore (i) what aspects of treatment the participants found to be helpful, and (ii) if there were areas that ought to be developed to make the protocol more useful to clients with ADHD-I.

METHODS

Participants were recruited from treatment groups following the protocol of cognitive-behavioral therapy for ADHD-I (CADDI), at three psychiatric outpatient units in Stockholm, Sweden. Individual semi-structured interviews, lasting on average 44,6 minutes, were conducted with 14 adults after the completion of CADDI. Interviews explored participants' perceptions of CADDI, its usefulness, and asked for suggestions for improvement. Interviews were conducted by independent interviewers and were transcribed verbatim. The text was analyzed using reflexive thematic analysis.

RESULTS

The analysis generated three themes: "Factors of importance for change", with the subthemes; the group, therapeutic components, structure of treatment, and motivation,"Gains in treatment", with the subthemes; insight and understanding, increased attention, and planning and acting, and "Challenges with ADHD-I and remaining needs", with the subthemes; ADHD as a lifelong condition, maintaining gains in treatment, and wish for further support.

CONCLUSIONS

Participants emphasized the importance of the group setting as a facilitator of therapeutic effects of increased understanding and self-acceptance. Further, they considered the practice of mindfulness to enhance attention and awareness of thoughts, feelings, and activities and considered the structure of treatment as supporting the work in therapy. These findings support the value of the group setting and confirm the usefulness of CADDI. However, participants were concerned about how to maintain gains of treatment after its termination and suggested follow-up sessions to improve the CADDI protocol.

Patient, supporter and primary healthcare professional perspectives on health risks in over 16s with attention deficit hyperactivity disorder (ADHD) in England: a national survey study

BACKGROUND

Current research suggests that people with attention deficit hyperactivity disorder (ADHD) are at higher risk of physical and mental health disorders. This study aimed to explore these health risks in ADHD from the perspectives of multiple stakeholders.

METHODS

This study forms part of the 'Managing young people with ADHD in Primary care (MAP) study'. A survey developed by the study team was distributed to over 16 year olds with ADHD, their supporters, primary healthcare professionals and health commissioners across England, via social media and through patient/clinical networks (September-October 2022). This survey contained two questions on health risks. Question one asked about views on health risks in ADHD (free text). Question two asked about advice given (options list and free text). Descriptive statistics summarised responses to questions one and two, and qualitative analysis (reflexive thematic analysis) was used to explore free text responses from question one.

RESULTS

782 participants responded to the MAP survey. Of these, 206 healthcare professionals, 157 people with ADHD and 88 supporters answered question one. The most mentioned perceived risks were substance misuse, sleep disorders, weight management and smoking. More people with ADHD reported disordered eating as a health risk (n = 32) than healthcare professionals (n = 5). Generated themes included perceived health risks, impact of living with ADHD, lack of adequate healthcare, and need for ADHD awareness. In respect to advice given (question two), based on responses from 258 professionals, 162 people with ADHD and 100 supporters, the most common advice discussed in consultation was mental health (n = 149, n = 50 and n = 17 respectively). High numbers of respondents reported not giving/receiving advice on wider health (n = 38, n = 88 and n = 61 respectively).

CONCLUSIONS

Findings demonstrate that respondents perceived a range of physical and mental health risks posed by ADHD. These related to difficulties with activities of daily living, as well as healthcare interactions and the impact of core features of ADHD (e.g. impulsivity, emotional dysregulation). These risks are not currently explicitly addressed in United Kingdom national guidance on ADHD. More work is needed to examine and address the broader health outcomes of people with ADHD.

Are all ADHD medications created equal? Exploring the differences that enable evening dosing

With more than 30 available stimulant medications, choosing among therapeutic options for attention-deficit/hyperactivity disorder (ADHD) has become increasingly complex and patient specific. All ADHD stimulants owe their action to variants of either amphetamine or methylphenidate, yet formulation and delivery system differences create unique pharmacokinetic and clinical profiles for each medication. A benefit of the diversity within ADHD pharmacotherapy is that it facilitates tailoring treatment to meet patient needs. Historically, there has been a constant among long-acting stimulant options, regardless of formulation, which was morning dosing. The introduction of delayed-release and extended-release methylphenidate (DR/ER-MPH) is the first long-acting stimulant that patients take in the evening, with the clinical effect delayed until awakening in the morning. This paradigm shift has generated questions among clinicians and continued interest in real-world experience and data. This review used available clinical data, real-world evidence, emerging analyses, and clinical experience to evaluate the characteristics of DR/ER-MPH and its clinical utility within the greater context of ADHD medications and to provide clinicians with practical guidance on the use of DR/ER-MPH in children, adolescents, and adults with ADHD.

Access to early diagnosis for attention-deficit/hyperactivity disorder among children and adolescents in Mexico City at specialized mental health services

BACKGROUND

In Mexico, this pioneering research was undertaken to assess the accessibility of timely diagnosis of Dyads [Children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) and their primary caregivers] at specialized mental health services. The study was conducted in two phases. The first phase involved designing an "Access Pathway" aimed to identify barriers and facilitators for ADHD diagnosis; several barriers, with only the teacher being identified as a facilitator. In the second phase, the study aimed to determine the time taken for dyads, to obtain a timely diagnosis at each stage of the Access Pathway. As well as identify any disparities based on gender and socioeconomic factors that might affect the age at which children can access a timely diagnosis.

METHOD

In a retrospective cohort study, 177 dyads participated. To collect data, the Acceda Survey was used, based on the robust Conceptual Model Levesque, 2013. The survey consisted of 48 questions that were both dichotomous and polytomous allowing the creation of an Access Pathway that included five stages: the age of perception, the age of search, the age of first contact with a mental health professional, the age of arrival at the host hospital, and the age of diagnosis. The data was meticulously analyzed using a comprehensive descriptive approach and a nonparametric multivariate approach by sex, followed by post-hoc Mann-Whitney's U tests. Demographic factors were evaluated using univariable and multivariable Cox regression analyses.

RESULTS

71% of dyads experienced a late, significantly late, or highly late diagnosis of ADHD. Girls were detected one year later than boys. Both boys and girls took a year to seek specialized mental health care and an additional year to receive a formal specialized diagnosis. Children with more siblings had longer delays in diagnosis, while caregivers with formal employment were found to help obtain timely diagnoses.

CONCLUSIONS

Our findings suggest starting the Access Pathway where signs and symptoms of ADHD are detected, particularly at school, to prevent children from suffering consequences. Mental health school-based service models have been successfully tested in other latitudes, making them a viable option to shorten the time to obtain a timely diagnosis.

Self-Esteem in Adults With ADHD Using the Rosenberg Self-Esteem Scale: A Systematic Review

OBJECTIVE

To summarize and analyze recent articles investigating self-esteem in adults with ADHD, focusing on the impact of demographic and clinical characteristics, and methodological issues.

METHOD

Following PRISMA guidelines, a systematic search for literature published between 2010 and 2022 was conducted in the Web of Science, Ovid, Pubmed, and EBSCO databases.

RESULTS

Eleven studies met inclusion criteria. Five of the six studies including healthy controls reported lower self-esteem in participants with ADHD. ADHD symptoms correlated negatively with self-esteem. Gender differences were not observed. Self-esteem mediated several outcomes associated with ADHD. There was a lack of studies that examined potential mechanisms behind the reduced self-esteem, and studies controlling for confounding variables.

CONCLUSION

A robust association between ADHD and low self-esteem in adults emerged, but the lack of control of confounding variables is critical to consider when interpreting the findings. Longitudinal studies addressing the limitations of the current studies are needed.

Association between ADHD symptoms and illicit stimulants use following 1 year among French university students of the i-Share cohort

PURPOSE

Although attention deficit hyperactivity disorder (ADHD) has been associated with illicit stimulants use, less is known about their prospective association in university students. We aimed to examine the association between ADHD symptoms at inclusion and illicit stimulants use following 1 year among university students.

METHODS

The i-Share cohort recruited French students from February 2013 to July 2020. The study included 4270 participants. The Adult ADHD Self-Report Scale (ASRS) was used to evaluate ADHD symptoms at inclusion. Illicit stimulants use was assessed at inclusion and 1 year after inclusion. Multivariable logistic regressions were conducted to assess the association between ADHD symptoms at inclusion and illicit stimulants use following 1 year.

RESULTS

High levels of ADHD symptoms at inclusion were associated with a greater probability of illicit stimulants use following 1 year (adjusted OR: 2.42 (1.51-3.8)). The adjusted odds ratio was 2.7 (1.08-7.84) among participants who had used illicit stimulant at least once (continuation) and 2.25 (1.04-4.37) among participants who had never used illicit stimulants at inclusion (initiation).

CONCLUSION

High levels of ADHD symptoms are a feature that may promote both initiation and continuation of illicit stimulants use among university students. Our findings suggest that university students with high levels of ADHD symptoms may benefit from screening to help identify those at risk of illicit stimulants use.

[Formula: see text] Environmental predictors of children's executive functioning development

Executive functioning (EF) abilities develop through childhood, but this development can be impacted by various psychosocial environmental influences. Using longitudinal data from the Health Outcome and Measures of the Environment (HOME) Study, a prospective pregnancy and birth cohort study, we examined if psychosocial environmental factors were significant predictors of EF development. Study participants comprised 271 children and their primary caregivers (98.5% mothers) followed from birth to age 12. We identified four distinct EF developmental trajectory groups comprising a consistently impaired group (13.3%), a descending impairment group (27.7%), an ascending impairment group (9.95%), and a consistently not impaired group (49.1%). Higher levels of maternal ADHD and relational frustration appear to be risk factors for increased EF difficulty over time, while higher family income may serve as a protective factor delaying predisposed EF impairment. Important intervention targets might include teaching positive and effective parenting strategies to mothers whose children are at risk for EF dysfunction.

Chronic Administration of Lisdexamfetamine Induces Apoptosis and Inflammation and Reduces Sperm Quality in Adult Male Rats

Concerns have been raised about potentially irreversible brain damage and damage to the neuroendocrine system during development when treating attention-deficit/hyperactivity disorder with lisdexamfetamine (LDX), a norepinephrine dopamine reuptake inhibitor. This study aims to elucidate the potential adverse effects of LDX on the male reproductive system due to its widespread use and potential for abuse. In this study, adult male rats were randomized into control and LDX groups. Thirty milligrams per kilogram LDX was administered orally for 3 weeks. After isolation of epididymal spermatozoa, the rats were euthanized and testicular tissues were collected for stereological and molecular analyses. The LDX group showed a decrease in sperm motility and an increase in DNA fragmentation compared to the control group. There was also a dramatic decrease in testosterone in the LDX group. Testicular expression of caspase-3 and TNF-α was significantly increased in the LDX group. According to our findings, prolonged use of LDX leads to reduced sperm quality. It also induces apoptosis, inflammatory response, and pathological changes in the testicular tissue. What we have observed in this study is noteworthy but requires further investigation, particularly in people who use LDX over a longer period of time.

A Female-Specific Treatment Group for ADHD-Description of the Programme and Qualitative Analysis of First Experiences

Background: The diagnostics and treatment of attention-deficit/hyperactivity disorder (ADHD) in women remain insufficient. Fluctuations of reproductive hormones during the premenstrual period, postpartum period, and (peri)menopause are neglected, even though they impact ADHD symptoms and associated mood disorders. Therefore, we created a female-specific treatment group for women with ADHD and premenstrual worsening of ADHD and/or mood symptoms. Methods: We describe the group programme and underlying rationale, offering a qualitative analysis of the participants' evaluation. Results: The seven bi-weekly sessions foreground the menstrual cycle and address several ADHD-specific topics in relation to this cyclical pattern. Concurrently, women track their menstrual cycle and (fluctuating) ADHD and mood symptoms with an adjusted premenstrual calendar. In total, 18 women (25-47 years) participated in three consecutive groups. We analysed the evaluation of the last group. Participants experienced the group as a safe and welcoming space. Recognition was valued by all. The topics discussed were deemed valuable, and the structure suited them well. Completing the premenstrual calendar augmented the awareness and recognition of individual cyclical symptoms. A lifespan approach increased self-understanding. Participants took their menstrual cycle more seriously, prioritising self-acceptance and self-care. Conclusions: Exploring a cyclical approach in a group setting seems to be a positive addition to treatment for female ADHD.

Vascular Burden Moderates the Relationship Between ADHD and Cognition in Older Adults

OBJECTIVES

Recent evidence suggests attention-deficit/hyperactivity disorder (ADHD) is a risk factor for cognitive impairment in later life. Here, we investigated cerebrovascular burden, quantified using white matter hyperintensity (WMH) volumes, as a potential mediator of this relationship.

DESIGN

This was a cross-sectional observational study.

SETTING

Participants were recruited from a cognitive neurology clinic where they had been referred for cognitive assessment, or from the community.

PARTICIPANTS

Thirty-nine older adults with clinical ADHD and 50 age- and gender-matched older adults without ADHD.

MEASUREMENTS

A semiautomated structural MRI pipeline was used to quantify periventricular (pWMH) and deep WMH (dWMH) volumes. Cognition was measured using standardized tests of memory, processing speed, visuo-construction, language, and executive functioning. Mediation models, adjusted for sex, were built to test the hypothesis that ADHD status exerts a deleterious impact on cognitive performance via WMH burden.

RESULTS

Results did not support a mediated effect of ADHD on cognition. Post hoc inspection of the data rather suggested a moderated effect, which was investigated as an a posteriori hypothesis. These results revealed a significant moderating effect of WMH on the relationship between ADHD memory, speed, and executive functioning, wherein ADHD was negatively associated with cognition at high and medium levels of WMH, but not when WMH volumes were low.

CONCLUSIONS

ADHD increases older adults' susceptibility to the deleterious cognitive effects of WMH in the brain. Older adults with ADHD may be at risk for cognitive impairment if they have deep WMH volumes above 61 mm3 and periventricular WMH above 260 mm3.

One-year follow-up of the effectiveness and mediators of cognitive behavioural therapy among adults with attention-deficit/hyperactivity disorder: secondary outcomes of a randomised controlled trial

BACKGROUND

The long-term effectiveness of cognitive behavioural therapy (CBT) in medicated attention-deficit/hyperactivity disorder (ADHD) adults with residual symptoms needs to be verified across multiple dimensions, especially with respect to maladaptive cognitions and psychological quality of life (QoL). An exploration of the mechanisms underlying the additive benefits of CBT on QoL in clinical samples may be helpful for a better understanding of the CBT conceptual model and how CBT works in medicated ADHD.

METHODS

We conducted a secondary analysis of a randomised controlled trial including 98 medicated ADHD adults with residual symptoms who were randomly allocated to the CBT combined with medication (CBT + M) group or the medication (M)-only group. Outcomes included ADHD-core symptoms (ADHD Rating Scale), depression symptoms (Self-rating Depression Scale), maladaptive cognitions (Automatic Thoughts Questionnaire and Dysfunctional Attitude Scale), and psychological QoL (World Health Organization Quality of Life-Brief Version-psychological domain). Mixed linear models (MLMs) were used to analyse the long-term effectiveness at one-year follow-up, and structural equation modeling (SEM) was performed to explore the potential mechanisms of CBT on psychological QoL.

RESULTS

ADHD patients in the CBT + M group outperformed the M-only group in reduction of ADHD core symptoms (d = 0.491), depression symptoms (d = 0.570), a trend of reduction of maladaptive cognitions (d = 0.387 and 0.395, respectively), and improvement of psychological QoL (d = - 0.433). The changes in above dimensions correlated with each other (r = 0.201 ~ 0.636). The influence of CBT on QoL was mediated through the following four pathways: 1) changes in ADHD core symptoms; 2) changes in depressive symptoms; 3) changes in depressive symptoms and then maladaptive cognitions; and 4) changes firstly in depressive symptoms, maladaptive cognitions, and then ADHD core symptoms.

CONCLUSIONS

The long-term effectiveness of CBT in medicated ADHD adults with residual symptoms was further confirmed. The CBT conceptual model was verified in clinical samples, which would be helpful for a deeper understanding of how CBT works for a better psychological QoL outcome.

Atypical sensory processing in adolescents with Attention Deficit Hyperactivity Disorder: A comparative study

Atypical sensory processing is common in Attention Deficit Hyperactivity Disorder (ADHD). Despite growing evidence that ADHD symptoms persist into adolescence, the sensory processing of individuals with ADHD in this age group is limited. The aim of this study was to assess differences in self-reported sensory experiences between adolescents with and without ADHD. One hundred thirty-eight Italian adolescents aged between 14 and 18 years (M=16.20; SD= ± 1.90) participated in the study. Sixty-nine participants with ADHD were matched by gender, age, and IQ to 69 typically developing individuals. The sensory processing of all participants was assessed using the Adolescent Sensory Profile (ASP) on the components: low registration, sensation seeking, sensory sensitivity, and sensation avoiding. Moreover, the modalities of ASP were measured: movement, vision, touch, activity level, hearing, and taste/smell. Results show that the ADHD group consistently displayed higher scores across all four components of the sensory profile compared to the control group. The subjects with ADHD also reported higher scores than the control group in all the modalities of ASP. These results confirming the presence of atypical sensory processing in adolescents with ADHD were discussed considering the Cumulative and Emergent Automatic Deficit model (CEAD).

Prevalence of Undiagnosed Attention Deficit Hyperactivity Disorder (ADHD) Symptoms in the Young Adult Population of the United Arab Emirates: A National Cross-Sectional Study

BACKGROUND

Attention deficit hyperactivity disorder (ADHD), a globally prevalent behavioural disorder, remains underdiagnosed, particularly among adults. This issue is exacerbated in the Arab region due to stigma and insufficient healthcare facilities and professionals. Despite the United Arab Emirates (UAE) efforts to improve mental healthcare, shortcomings persist. No studies in the UAE currently assesses the appropriateness of the screening system for ADHD and other behavioural issues. Furthermore, prevalence rates of ADHD, particularly within the young adult population, are absent.

AIM

To estimate the prevalence of ADHD amongst young adults attending university in UAE and examine its relationship with gender and academic outcomes.

METHODS

A cross-sectional, correlational design was used. Young adults in their first year at university were recruited from different academic institutions across the UAE. The study utilized the Adult ADHD Self-Report Scale (ASRS) for data collection.

RESULTS

A sample of 406 young adults, aged between 18 and 20 years of age were recruited. Approximately, 34.7% (n = 141) reported symptoms suggestive of probable ADHD. Significantly lower grade point average marks were observed in participants with ADHD symptoms (M = 3.15) compared to those without (M = 3.35). Females reported symptoms of probable ADHD at higher rates than males, indicating possibly a potential screening deficiency and a potential stigma consequence.

CONCLUSIONS

The study demonstrates a high prevalence of probable ADHD in young adults, particularly among females attending university in the United Arab Emirates. Implications for early screening, service provision, and greater professional health training on this disorder are required.

Attention deficit and hyperactivity disorder and use of psychostimulants in Aotearoa, New Zealand: exploring the treatment gap

Introduction Attention deficit and hyperactivity disorder (ADHD) is a common neurodevelopmental disorder affecting about 7% of those aged up to 12 years, 5% of teenagers and 3% of adults. It is associated with poor academic performance, substance abuse, criminality, poor social functioning and other negative outcomes. Psychotherapeutic treatment is moderately successful, whereas pharmacotherapy with stimulant medication is more efficacious and is recommended in many international guidelines. Anecdotal evidence suggests underuse of these medications in Aotearoa, New Zealand. Aim To estimate how many patients with ADHD are prescribed psychostimulants in Aotearoa, New Zealand. Methods National prescribing data for dexamphetamine and methylphenidate in 2022 were obtained and matched against estimated prevalence of ADHD by age. Results There is a significant treatment gap for which inability to access first-line medication is likely to be the predominant explanation. Discussion The data suggest failure of our health system to provide reasonable health care for a significant number of people with ADHD, and results in inequity in outcomes. New approaches are needed that will increase access to first-line medication, yet maintain appropriateness of diagnosis and limit risk of medication diversion.

Effects of psychedelic microdosing versus conventional ADHD medication use on emotion regulation, empathy, and ADHD symptoms in adults with severe ADHD symptoms: A naturalistic prospective comparison study

Adults with attention-deficit hyperactivity disorder (ADHD) often struggle with emotion regulation (ER), impacting their empathic skills and relationships. ADHD medication might not be as effective for ER issues as for ADHD symptoms. Microdosing (MD) psychedelics has shown promise for ADHD treatment and previous studies reported social-emotional benefits. Two online prospective studies investigated MD effects on ER and empathy in adults with severe ADHD symptoms across three assessments: baseline, two-, and four-week post-initiation. Study 1 examined adults initiating MD on their own (n = 233, n = 64, and n = 44) and found positive effects on ER (cognitive reappraisal and expressive suppression) and aspects of empathy (perspective-taking and personal distress). Study 2, including a control group and an ADHD symptom scale, compared individuals only MD (n = 180, n = 50, and n = 38) to individuals using conventional ADHD medication (n = 37, n = 27, and n = 28). After 4 weeks, ADHD symptoms were lower in the MD group. Only improvements in expressive suppression persisted after adding the control group. This study indicates the positive effects of MD psychedelics on ADHD symptoms and ER in adults with severe ADHD symptoms while lacking evidence for effects on empathy.

Drivers and Barriers to Tolerable and Effective Treatment for ADHD: The Importance of Treatment Perseverance and Duration of Effect

OBJECTIVE

To examine treatment outcomes for classes of ADHD drugs in conjunction with physicians' prescribing rationales and the utility of treatment perseverance in treatment effectiveness.

METHODS

A retrospective non-interventional study using physician-provided chart data for treated adolescent and adult ADHD patients in the United States (April-June 2019). Multivariable analyses compared the effectiveness and tolerability of drug classes.

RESULTS

Among the 1,232 ADHD patients included in this study, 37.7% experienced one, 11.8% two, and 6.7% three treatment changes post their first prescribed regimen. These changes were mostly attributed to lack of rapid onset and duration of effect. Achieving best response correlated with the number of previous treatments for adolescents, but not adults. Maintaining full response correlated with the length of current treatment for adolescents and adults.

CONCLUSION

Physicians' prescribing rationales targeted duration of effect and tolerability. ER monotherapy demonstrated potential advantages over other regimens. Treatment perseverance is integral to effective ADHD management.

The course of attention-deficit/hyperactivity disorder through midlife

The course of ADHD from childhood up to young adulthood has been characterized in several studies. However, little is known about the course of symptoms into middle age and beyond. This study aims to evaluate predictors of ADHD trajectories in midlife based on three assessments. The follow-up sample comprised 323 adults with ADHD, evaluated at baseline and seven and thirteen years later, from the average ages of 34 up to 47 years old. ADHD status at reassessments was used to characterize trajectories. Demographics, ADHD features, comorbidities, and polygenic scores for ADHD and genetically correlated psychiatric disorders were evaluated to predict ADHD trajectories. Study retention rate was 67% at T2 (n = 216) and 62% at T3 (n = 199). Data from patients evaluated three times showed that 68.8% coursed stable, 25.5% unstable, and 5.7% remission trajectory of ADHD. Women, individuals with more severe syndromes, higher frequency of comorbidities at reassessments, and genetic liability to depression present a higher probability of a stable trajectory. Our findings shed light on midlife ADHD trajectories and their gender, genomic and clinical correlates.

Barriers and Enablers of Service Access and Utilization for Children and Adolescents With Attention Deficit Hyperactivity Disorder: A Systematic Review

OBJECTIVE

To update a systematic review of the literature on the barriers and enablers of service access and utilization for children and adolescents with a diagnosis, or symptoms of attention deficit/hyperactivity disorder (ADHD), from the perspective of caregivers, clinicians, and teachers.

METHODS

Five databases were searched for peer-reviewed literature published from May 2012 to March 2023. Two independent reviewers completed a two-stage screening process and quality assessment.

RESULTS

Of 4,523 search results, 30 studies were included. Five main themes were generated: 1) Awareness of ADHD, 2) Stigma, 3) Parental choice and partnerships, 4) Education services as an integral component, 5) Referrals, waiting times, and logistics. More than half of the studies reported poor acknowledgement, expertise of ADHD, and stigma.

CONCLUSION

Findings highlight the need for ongoing ADHD education for all involved and policy changes to service delivery systems to increase the availability of health providers with specialist ADHD expertise.

Treatment of adult attention-deficit hyperactivity disorder (ADHD) with transcranial direct current stimulation (tDCS): study protocol for a parallel, randomized, double-blinded, sham-controlled, multicenter trial (Stim-ADHD)

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation treatment used as an alternative or complementary treatment for various neuropsychiatric disorders, and could be an alternative or add-on therapy to psychostimulants in attention-deficit hyperactivity disorder (ADHD). Previous studies provided some evidence for improvements in cognition and clinical symptoms in pediatric and adult ADHD patients. However, data from multi-center randomized controlled trials (RCTs) for this condition are lacking. Thus, our aim is to evaluate short- and mid-term effects of tDCS in this multi-center, randomized, double blind, and sham-controlled, parallel group clinical trial with a 1:1 randomization ratio. Primary endpoint is the total score of DSM-IV scale of the internationally established Conners' Adult ADHD Rating Scales (German self-report screening version, CAARS-S-SR), at day 14 post-intervention (p.i.) to detect short-term lasting effects analyzed via analyses of covariance (ANCOVAs). In case of significant between-groups differences at day 14 p.i., hierarchically ordered hypotheses on mid-term lasting effects will be investigated by linear mixed models with visit (5 time points), treatment, treatment by visit interaction, and covariates as fixed categorical effects plus a patient-specific visit random effect, using an unstructured covariance structure to model the residual within-patient errors. Positive results of this clinical trial will expand the treatment options for adult ADHD patients with tDCS and provide an alternative or add-on therapy to psychostimulants with a low risk for side effects.Trial Registration The trial was registered on July 29, 2022 in the German Clinical Trials Register (DRKS00028148).

Limited usefulness of neurocognitive functioning indices as predictive markers for treatment response to methylphenidate or neurofeedback@home in children and adolescents with ADHD

Introduction

Earlier studies exploring the value of executive functioning (EF) indices for assessing treatment effectiveness and predicting treatment response in attention-deficit/hyperactivity disorder (ADHD) mainly focused on pharmacological treatment options and revealed rather heterogeneous results. Envisioning the long-term goal of personalized treatment selection and intervention planning, this study comparing methylphenidate treatment (MPH) and a home-based neurofeedback intervention (NF@Home) aimed to expand previous findings by assessing objective as well as subjectively reported EF indices and by analyzing their value as treatment and predictive markers.

Methods

Children and adolescents (n = 146 in the per protocol sample) aged 7-13 years with a formal diagnosis of an inattentive or combined presentation of ADHD were examined. We explored the EF performance profile using the Conners Continuous Performance Task (CPT) and the BRIEF self-report questionnaire within our prospective, multicenter, randomized, reference drug-controlled NEWROFEED study with sites in five European countries (France, Spain, Switzerland, Germany, and Belgium). As primary outcome for treatment response, the clinician-rated ADHD Rating Scale-IV was used. Patients participating in this non-inferiority trial were randomized to either NF@home (34-40 sessions of TBR or SMR NF depending on the pre-assessed individual alpha peak frequency) or MPH treatment (ratio: 3:2). Within a mixed-effects model framework, analyses of change were calculated to explore the predictive value of neurocognitive indices for ADHD symptom-related treatment response.

Results

For a variety of neurocognitive indices, we found a significant pre-post change during treatment, mainly in the MPH group. However, the results of the current study reveal a rather limited prognostic value of neurocognitive indices for treatment response to either NF@Home or MPH treatment. Some significant effects emerged for parent-ratings only.

Discussion

Current findings indicate a potential value of self-report (BRIEF global score) and some objectively measured neurocognitive indices (CPT commission errors and hit reaction time variability) as treatment markers (of change) for MPH. However, we found a rather limited prognostic value with regard to predicting treatment response not (yet) allowing recommendation for clinical use. Baseline symptom severity was revealed as the most relevant predictor, replicating robust findings from previous studies.

The impact of emotional dysregulation and comorbid depressive symptoms on clinical features, brain arousal, and treatment response in adults with ADHD

Introduction

The role of emotional dysregulation (ED) in attention-deficit/hyperactivity disorder (ADHD) has become an important issue. This study, in which we analyzed data from a predictive pharmaco-EEG-trial, aimed to examine whether symptoms of ED in adult ADHD affect ADHD symptom severity, brain arousal regulation as measured by resting EEG, and the response to stimulant medication.

Methods

ED is defined as having a sex- and age-corrected T-score of >70 on the emotional lability subscale of the German version of Conners' Adult ADHD Rating Scale. A total of 115 participants were included in the study, 56 of whom had ED. Participants with ED were more impaired in terms of the severity of core ADHD symptoms, especially inattentive symptoms, comorbid depressive symptoms, interpersonal relationships, and quality of life. In addition, participants with ED were more likely to report a total score above 13 on the Beck Depression Inventory-II, which was considered to be the cutoff for mild depression.

Results

No differences were found between the ED and non-ED groups in response to stimulant medication or in brain arousal regulation. In addition, there was no significant effect of ED with comorbid depressive symptoms on treatment response. There was a trend for subgroups that showed a change in brain arousal regulation associated with symptom improvement.

Discussion

Our findings may support the assumption that ED may be an important feature of ADHD. The use of EEG-based brain arousal regulation as a diagnostic and predictive tool in ADHD in the presence of ED and comorbid depressive symptoms should be further investigated.

[Attention deficit hyperactivity disorder in adults]

The article presents a review of scientific publications devoted to the study of the characteristics of the clinical picture and the dynamics of the main symptoms in adult patients with attention deficit hyperactivity disorder (ADHD). The authors present current data on the prevalence of this disease, leading clinical manifestations and the most common comorbid pathology. Research data on the impact of ADHD in adulthood on educational and professional activities are presented, and the economic and criminological aspects of ADHD are considered. The main methods of psychotherapeutic correction and pharmacological therapy are presented.

The socioeconomic burden of adult attention-deficit/hyperactivity disorder in Spain

Introduction

The symptoms of attention-deficit/hyperactivity disorder (ADHD) in adults highly interfere with function in multiple dimensions, increasing the economic burden associated with ADHD. The aim of this study was to explore the impact of ADHD in Spanish adults and estimate the associated economic burden within the healthcare, social, economic, and legal domains.

Methods

An economic model was developed from a social perspective using a bottom-up approach, based on the scientific literature and a multidisciplinary expert group.

Results

The cost incurred per diagnosed adult patient with ADHD included an annual cost of €15,652 and a one-time cost of €7,893 (3,035 M€ and 1,531 M€ for Spain, respectively). Regarding the annual cost, 50% was attributed to costs within the economic domain, of which 53% were work-absenteeism-related. Moreover, 28% was attributed to costs within the social domain, of which 74% were substance-abuse-related. Regarding the one-time cost, 52% was attributed to costs within the healthcare domain, of which approximately 50% were hospitalization-related costs. Moreover, 42% was attributed to costs within the legal domain, of which 62% were imprisonment-related costs.

Conclusions

This is the first report on the socioeconomic burden of ADHD in Spanish adults, shedding light on the large burden that adult ADHD poses on the healthcare system and society at large, as symptoms have been shown to impact almost every aspect of life. This is particularly important for undiagnosed/untreated patients with ADHD in Spain, as appropriate treatments have shown positive results in these areas and may reduce its associated socioeconomic burden.
