Functional impairments among adults with ADHD: A comparison with adults with other psychiatric disorders and links to executive deficits

Distracted, hyperactive, and thriving: factors supporting everyday functioning in adults with ADHD

BACKGROUND

Using a strengths-based framework, the present study sought to identify protective personal and social characteristics associated with functional ability among adults with attention-deficit/hyperactivity disorder (ADHD).

METHODS

Sixty-four adults with ADHD (19-80 years old) completed self-report measures of everyday functioning, psychiatric symptoms, personality, social support, and coping strategies. Conscientious and extraverted personality traits, adaptive coping strategies, positive childhood experiences and available social support were investigated as potential protective factors supporting everyday functioning through partial correlation analyses adjusting for ADHD symptom severity and comorbid symptoms of depression and anxiety. Significant correlates were tested as modifiers of ADHD-related functional impairments in moderated regression models.

RESULTS

Multiple significant correlations were found between functional impairment and each of the personality and social characteristics of interest. Positive childhood experiences and emotion-focused coping strategies were linked to better community functioning, and positive childhood experiences were also linked to better sexual functioning. Forms of tangible, belonging and self-esteem support were associated with better functioning in social and sexual relationships, as well as with overall functional ability. None of these factors moderated the association between ADHD symptom severity and overall functioning, indicating that the functional advantages of social support were observed regardless of the severity levels of ADHD symptoms or functional impairment.

CONCLUSION

Higher ratings of social support were linked to better functioning across many life domains independent of ADHD symptom severity, suggesting that all people with ADHD - even those with relatively low symptoms - may thrive from the development of enhanced social connections. These conclusions need to be strengthened by supportive longitudinal evidence, as it is likely that many of these associations are bi-directional.

Conceptualizing adult ADHD with the DSM alternative model of personality disorder

Personality traits and personality disorders are related to ADHD and indicate dysfunction in clinical populations. The goals of this study were to examine how the DSM-5 Alternative Model of Personality Disorder (AMPD) a) indicates the presence of ADHD and b) communicates information about dysfunction over and above ADHD diagnosis. A sample of 330 adult psychiatric patients with and without ADHD (60% female; mean age 33 years) were assessed for ADHD symptoms, personality impairment, maladaptive personality traits, and functional life impairment domains. The maladaptive personality domain Disinhibition and particularly the lower order facet of Distractibility distinguished between individuals with psychiatric difficulties with and without ADHD. Distractibility is strongly related to the ADHD symptom dimension Inattentiveness, and Antagonism to Hyperactivity/impulsivity. General personality impairment augmented ADHD diagnosis in predicting life impairments. The AMPD has utility in ADHD assessments for diagnosis and prognosis.

The Work and Social Adjustment Scale (WSAS): An investigation of reliability, validity, and associations with clinical characteristics in psychiatric outpatients

OBJECTIVE

This study, the first to assess the reliability and validity of the Work and Social Assessment Scale (WSAS) in Norwegian routine mental health care, examines differences in functional impairment based on sick leave status, psychiatric diagnosis, and sex.

METHOD

Including 3573 individuals from community mental health services (n1 = 1157) and a psychiatric outpatient clinic (n2 = 2416), exploratory factor analysis (EFA) on subsample 1 and confirmatory factor analysis (CFA) on subsample 2 were utilized to replicate the identified factor structure.

RESULTS

EFA supported a one-factor model, replicated by the CFA, with high internal consistency (α = .82, ω = .81). Patients on sick leave reported greater impairments in all aspects of functioning, except for relationships, with the largest effect size observed in the reported ability to work (d = .39). Psychiatric outpatients with major depressive disorder were associated with difficulties in home management, private leisure activities, and forming close relationships. Patients with attention-deficit/hyperactivity disorder reported less impairment than those with other disorders. Patients with personality disorders reported more relationship difficulties than those with PTSD, ADHD, and anxiety. No differences were found in the perceived ability to work between diagnoses. Women had a higher impairment in private leisure activities, whereas men reported more impairment in relationships.

CONCLUSION

The demonstrated reliability and validity suggest that WSAS is a valuable assessment tool in Norwegian routine mental health care. Variations in functional impairment across sick leave status, sex, and psychiatric diagnoses highlight the importance of integrating routine assessments of functional impairment into mental health care practices. Future research should combine WSAS with register data to allow for a broader understanding of treatment effectiveness, emphasizing improvements in functional outcomes alongside symptom alleviation.

Functional impairment and quality of life in newly diagnosed adults attending a tertiary ADHD clinic in Ireland

BACKGROUND

Attention Deficit-Hyperactive Disorder (ADHD) is a neurodevelopmental disorder, often persisting into adulthood.

AIMS

To investigate the levels of functionality and quality of life (QoL) in adult patients newly diagnosed with ADHD and to compare with those without an ADHD diagnosis.

METHODS

Consecutive patients who were referred to and assessed in a tertiary adult ADHD clinic enrolled in the study. Diagnosis of ADHD was based on DSM-5 criteria. Functionality was measured using the Weiss Functional Impairment Rating Scale (WFIRS) and the Global Assessment of Functioning Scale (GAF). QoL was assessed with the Adult ADHD Quality of Life Questionnaire (AAQoL).

RESULTS

Three-hundred and forty participants were recruited, 177 (52.1%) females. Of them 293 (86.2%) were newly diagnosed with ADHD. Those with ADHD had significant lower functionality as it was measured with the WFIRS and GAF, and worse QoL (AAQoL) compared to those without. In addition, a significant correlation between GAF and WFIRS was found.

CONCLUSIONS

The results show that adults with ADHD have decreased functionality and worse QoL when compared against those presenting with a similar symptomatology, but no ADHD diagnosis. ADHD is not just a behavioural disorder in childhood, but a lifelong condition with accumulating problems that can lead to lower QoL and impaired functioning throughout adulthood.

Formulation-based cognitive behavioral therapy compared to an active control and a waitlist in adult inmates with ADHD: study protocol for a randomized controlled trial

BACKGROUND

Recent literature suggests that ADHD is a risk factor for the development of antisocial behavior that is more severe and persistent than in community and other psychiatric populations. The combination of stimulant medication and psychotherapy (particularly cognitive behavioral therapy, CBT) is considered an evidence-based intervention for adults with ADHD. In contrast, few studies have evaluated the efficacy of medication in adult prisoners with ADHD, and the literature on the efficacy of psychotherapy is virtually nonexistent. Therefore, this article presents the protocol of a trial that will assess the efficacy of a formulation-based CBT program for inmates with ADHD.

METHODS

The study has a multicenter randomized controlled trial design. After screening and recruitment, participants will be randomly assigned to the CBT intervention, a general offender treatment program, or a waitlist. Pre- and post-treatment self-report and clinician-report assessments, as well as 6- and 12-month follow-up assessments will be conducted. These will include both clinical (e.g., ADHD symptoms, depression and anxiety symptoms, self-esteem, alcohol/drug abuse, treatment adherence, quality of life) and criminological (e.g., recidivism and risk of recidivism) measures. Linear mixed models will be used to assess differences between groups.

DISCUSSION

This study may be the first to evaluate the efficacy of a psychotherapy intervention in adult inmates with ADHD. It is expected that addressing the specific needs of ADHD would not only result in the previously reported clinical improvements (e.g., reduction in ADHD and comorbidity symptoms), but also reduce the risk and rate of recidivism compared to the general intervention or no intervention. However, the design may be limited by the difficulties inherent in the prison setting and in following up the sample after release.

Differences in executive functioning between adults with ADHD and those diagnosed with other psychiatric diagnoses: Utility of the CTMT and the WAIS-IV

In this study, the utility of the Comprehensive Trail Making Test (CTMT) and WAIS-IV working memory (WMI) and processing speed (PSI) indices in assessment of ADHD were examined. Using retrospective analysis of data from two private practices, patients were classified as having ADHD, having another psychiatric disorder, or having comorbid ADHD and other psychiatric disorder. Results indicated that significant differences existed in performance across the three groups [F(6, 246) = 3.38, p = .003; Pillai's Trace = 0.152, partial η2 = 0.076] on CTMT scores (p < .05), WMI scores (p ≤ .001) and PSI scores (p < .05). Logistic regression analyses indicated WMI and CTMT trail 5 scores were individually useful indicators in identifying the presence of ADHD. Analysis also indicated minimal increase in correct classification of presence or absence of ADHD through combining CTMT, WMI, and PSI scores. Clinical implications for neuropsychological assessment and differential diagnosis of ADHD are discussed.

Prevalence, Correlates, and Comorbidities Among Young Adults Who Screened Positive for ADHD in South Korea During the COVID-19 Pandemic

OBJECTIVE

This study examined the prevalence, associated factors, and psychiatric comorbidities of adult ADHD during the COVID-19 pandemic by analyzing nationally representative data.

METHODS

Among the 5,511 respondents of the 2021 National Mental Health Survey, South Korea, 2,764 (18-49 years) were selected. The Korean versions of the Adult ADHD Self-Report Scale, Composite International Diagnostic Interview, and Structured Clinical Interview for Internet Gaming Disorder were used as diagnostic assessments.

RESULTS

The 6-month prevalence of positive screens for adult ADHD was 3.1%. In individuals aged 18 to 29 years exhibiting adult ADHD symptoms, high prevalence rates of alcohol use, depression, and Internet gaming disorders were observed in the last 12 months. Adults who screened positive for ADHD reported significantly lower life satisfaction and resilience, and higher loneliness and social isolation (vs. non-ADHD group).

CONCLUSION

Adult ADHD symptoms significantly influenced mental well-being, highlighting the need for an appropriate treatment/prevention system, particularly for individuals aged 18 to 29 years.

Executive function deficits mediate the relationship between employees' ADHD and job burnout

Adults with Attention-Deficit/Hyperactivity Disorder (ADHD) often face significant deficits in executive function and adverse work-related outcomes. This study aimed to explore the role of executive function deficits in job burnout of employees with ADHD. We hypothesized that employees with ADHD, relative to employees without ADHD, will experience higher levels of job burnout and deficits in executive function. We also hypothesized that the ADHD-job burnout relationship would be mediated through executive function deficits, specifically by self-management to time and self-organization/problem-solving. A field study with 171 employees provided support for the research hypotheses and mediation model in which the employees' ADHD-job burnout relationship was mediated through executive function deficits. Additional mediation analyses indicated that the specific executive function of self-management to time and self-organization/problem-solving mediated the effect of ADHD on job burnout and its facets. Specifically, for physical fatigue, the mediation was realized through self-management to time, and for emotional exhaustion and cognitive weariness, the mediation was significant through self-organization/problem-solving. The present findings shed light on the relevance of referring ADHD among employees, their vulnerability to job burnout, and the role of executive function deficits in job burnout of employees with ADHD.

The Role of Age in Adult ADHD Quality Care: A Longitudinal Analysis of Electronic Health Record Data

OBJECTIVE

Several studies have shown that Adult ADHD presents differently in younger and older adults. We sought to assess the difference in care between these two groups using previously identified quality measures (QMs).

METHODS

Using electronic health record data, we matched a younger group of ADHD patients to an older group. We then assessed the achievement of the QMs using probit models with and without interaction terms.

RESULTS

The majority of QMs shown an increase in achievement for both groups over time. However, significant differences in quality of care between younger and older adult ADHD patients persisted. By the end of the study period, with the exception of three QMs, younger patients achieved the QMs more.

CONCLUSION

While, in general, the quality of care for adult ADHD increased from 2010 to 2020, there were still differences in care between younger and older adult ADHD patients.

Differences in Primary Care Management of Patients With Adult Attention Deficit Hyperactivity Disorder (ADHD) Based on Race and Ethnicity

OBJECTIVE

Examine differences in care patterns around adult ADHD between race (White/Non-White) and ethnic (Hispanic/Non-Hispanic) groups utilizing existing quality measures (QMs), concerning diagnosis, treatment, and medication prescribing.

METHODS

The AAFP National Research Network in partnership with SUNY Upstate Medical used an EHR dataset to evaluate achievement of 10 ADHD QMs. The dataset was obtained from DARTNet Institute and includes 4 million patients of 873 behavioral and primary care practices with at least 100 patients from 2010 to 2020. Patients 18-years or older with adult ADHD were included in this analysis.

RESULTS

White patients and Non-Hispanic/Latinx patients were more likely to achieve these QMs than Non-White patients and Hispanic/Latinx patients, respectively. Differences between groups concerning medication and monitoring demonstrate a disparity for Non-White and Hispanic/Latinx populations.

CONCLUSIONS

Using QMs in EHR data can help identify gaps in ADHD research. There is a need to continue investigating disparities of quality adult ADHD care.

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.

Exploring the efficacy of dialectical behaviour therapy and methylphenidate on emotional comorbid symptoms in adults with attention Deficit/Hyperactivity disorder: Results of the COMPAS multicentre randomised controlled trial

This study evaluated the efficacy of dialectical behaviour group therapy (GPT) vs. individual clinical management (CM) and methylphenidate (MPH) vs. placebo (PLB) on emotional symptoms in adults with ADHD. This longitudinal multicentre RCT compared four groups (GPT+MPH, GPT+PLB, CM+MPH, and CM+PLB) over five assessment periods, from baseline to week 130. Emotional symptomatology was assessed using SCL-90-R subscales. Of the 433 randomised participants, 371 remained for final analysis. At week 13, the GPT+MPH group showed smaller reductions in anxiety symptoms than the CM groups, but the differences disappeared at subsequent assessments. Improvements in emotional symptom were significantly predicted by reductions in core ADHD symptoms in all groups except the GPT+MPH group. The unexpected lack of between-group differences may be explained by a "floor effect", different intervention settings (group vs. individual), and psychotherapy type. Multiple regression analyses suggest a more specific effect of combined interventions (GPT+MPH). Implications for clinical practice are discussed. Clinical trial registration: ISRCTN54096201 (Current Controlled Trials).

Fronto-parietal white matter microstructure associated with working memory performance in children with ADHD

INTRODUCTION

Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder with many functional impairments thought to be underpinned by difficulties in executive function domains such as working memory. The superior longitudinal fasciculus (SLF) plays an integral role in the development of working memory in neurotypical children. Neuroimaging research suggests reduced white matter organization of the SLF may contribute to working memory difficulties commonly seen in ADHD. This study aimed to examine the relationship between white matter organization of the SLF and working memory in children with ADHD.

METHODS

We examined the association of tract volume and apparent fibre density (AFD) of the SLF with working memory in children with ADHD (n = 64) and controls (n = 58) aged 9-11years. Children completed a computerized spatial n-back task and underwent diffusion magnetic resonance imaging (dMRI). Constrained spherical deconvolution-based tractography was used to construct the three branches of the SLF bilaterally and examine volume and AFD of the SLF.

RESULTS

Regression analyses revealed children with ADHD exhibited poorer working memory, and lower volume and AFD of the left SLF-II compared to healthy controls. There was also an association between reaction time and variability (RT and RT-V) and the left SLF-II. Further analyses revealed volume of the left SLF-II mediated the relationship between ADHD and working memory performance (RT and RT-V).

DISCUSSION

These findings add to the current body of ADHD literature, revealing the potential role of frontoparietal white matter in working memory difficulties in ADHD.

Functional Impairments Associated With ADHD in Adulthood and the Impact of Pharmacological Treatment

OBJECTIVE

Among untreated adults, functional impairments associated with ADHD are widespread and cumulative, and can include social, educational, and professional impairments, increased risk of accidents and mortality, and reduced quality of life. Here, we review the most prominent functional impairments in adults with ADHD and summarize evidence describing the potential role of medication in improving outcomes.

METHOD

Articles related to the search terms "ADHD," "adult," and functional impairments were identified through Google Scholar and PubMed and selected for inclusion based on four criteria: strength of evidence, relevance to current challenges in adult ADHD, impact on the field, and recency of the results.

RESULTS

We identified 179 papers to support the conclusions on the relationship between ADHD and functional impairments, and the impact of pharmacological therapy on functional impairments.

CONCLUSION

This narrative review provides evidence that pharmacological treatment can be effective in minimizing not only the symptoms of ADHD, but its functional consequences as well.

ADHD and associated psychopathology in older adults in a German community sample

Attention deficit hyperactivity disorder (ADHD) is still a neglected disorder in older adults. The aim of the present study was to examine the prevalence and symptomatology of ADHD and associated psychopathology in adults aged 40-80 years in a German community sample. We examined 539 participants in two age groups: (1) 40-59 years old (n = 256) and (2) 60-80 years old (n = 283). To assess ADHD in both childhood and adulthood as well as current psychopathological impairments, we used self-report instruments and corresponding observer reports. We examined group differences between age groups and between ADHD and non-ADHD groups. The prevalence of ADHD in the total sample was 2.6% with no significant differences between the two age groups (40-59 years: 3.1% vs. 60-80 years: 2.1%). Although differences emerged in impulsivity/emotional lability and self-concept problems, overall ADHD symptom ratings did not differ between the age groups. The ADHD group showed more psychopathological peculiarities compared to individuals without ADHD with medium-to-large effect sizes. Self-reports and observer reports showed good concordance in the assessment of ADHD and comorbid psychopathological symptoms. Regarding current ADHD symptomatology, in 92.1%, self-report was corroborated by observer's information. Our findings underline that ADHD symptoms are relevant across the lifespan. Augmenting self-reports with observer reports could increase the assessment quality of ADHD. For successful treatment, clinicians should also focus on additional psychopathological impairments and comorbidities in older adults with ADHD.

Predictors of Quality of Life and Functional Impairments in Emerging Adults With and Without ADHD: A 10-Year Longitudinal Study

OBJECTIVE

We tested the hypotheses that (1) a diagnosis of ADHD in childhood or adolescence is associated with reduced quality of life (QoL) and everyday functioning in emerging adulthood, and (2) executive function (EF) deficits, internalizing difficulties, and ADHD symptoms predict reduced QoL and more functional impairments.

METHOD

We assessed 85 children and adolescents with ADHD and 50 typically developing (TD) peers at baseline (M_age = 11.6 years, 58% males), 2-year follow-up, and 10-year follow-up with neuropsychological tests of EF and self-reports.

RESULTS

Individuals with ADHD reported lower QoL and functional impairments in emerging adulthood compared to TD peers. More internalizing difficulties and ADHD symptoms at baseline and 2-year follow-up significantly predicted lower QoL and more functional impairments at the 10-year follow-up.

CONCLUSION

ADHD and internalizing difficulties in childhood or adolescence have a negative impact on QoL and everyday functioning in emerging adulthood.

The relationship between executive function, neurodevelopmental disorder traits, and academic achievement in university students

Difficulties with executive function have often been identified in individuals with various neurodevelopmental disorders such as Autism Spectrum Disorder (ASD), Attention-Deficit Hyperactivity Disorder (ADHD), and Developmental Co-ordination Disorder (DCD). Additionally, in childhood and adolescence, executive functioning is an important predictor of academic achievement. However, less research has explored these relationships in adult students, and those with a high level of neurodevelopmental disorder traits but no clinical diagnosis. Therefore, the current study aimed to assess whether ASD, ADHD, and DCD traits can predict academic achievement in university students, and whether traits of these neurodevelopmental conditions moderate the relationship between executive function and academic achievement. Both neurotypical students and those with a clinical diagnosis of a neurodevelopmental disorder were able to participate, with the majority being neurotypical. Participants completed four self-report questionnaires and provided a measure of academic achievement based on their university assignment results. Traits of ASD, ADHD, and DCD alone did not predict achievement, however, traits of ADHD and DCD significantly moderated the relationship between executive function and academic achievement. ASD traits did not significantly moderate this relationship. Implications and suggestions for future research are also discussed.

Everyday flexibility and functional milestones in anorexia nervosa: survey results from a mixed community sample

PURPOSE

This study examined the relationship between self-reported cognitive-behavioral flexibility scores on the Eating Disorder Flexibility Index (EDFLIX) and objective social and occupational functional milestones in participants with a lifetime diagnosis of anorexia nervosa (AN). The Work and Social Adjustment Scale (WSAS) was included to compare objective and subjective measures.

METHODS

114 female adult participants with a current (53.5%) or past (46.5%) full or partial AN syndrome diagnosis completed an online survey which included functional milestone questions, the EDFLIX, WSAS, EDE-Q, and DASS-21.

RESULTS

Everyday flexibility scores were significantly associated with WSAS scores, but not functional milestones for the same domain. Lower flexibility was related to higher WSAS work impairment but was not associated with poor occupational outcomes. Lower flexibility was related to higher WSAS social impairment but was not associated with less frequent social contact with friends. Milestones across work, social and relationship areas were not significantly correlated, suggesting individuals have areas of strength and weakness across functional domains. In contrast, WSAS ratings indicated broad functional impairment.

CONCLUSION

Results from the milestones suggest self-reported cognitive-behavioral flexibility is not a strong determinant of everyday function. Results from the subjective WSAS function measure and the more objective functional milestones were not consistent. To obtain a more balanced assessment of everyday functioning in AN, both subjective and objective measures should be considered.

ADHD prevalence in the psychiatric population

OBJECTIVE

This article presents a systematic literature review of the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) in the adult psychiatric population.

METHODS

Three databases were searched using keywords relating to ADHD and psychiatric disorders. Fifteen studies published before May 2020 met inclusion criteria.

RESULTS

Prevalence rates ranged from 6.9 to 38.75%. There was considerable heterogeneity with regards to the assessment methods of ADHD and comorbidities, the sampling as well as inclusion and exclusion of psychiatric comorbidities. Research concluded that ADHD is underdiagnosed in this population. Gender ratios also varied between 1.8:1 and 1:2.5 (male:female).

CONCLUSIONS

All ADHD prevalence rates for the psychiatric population were considerably higher than the 2.8% estimated for the general adult population. ADHD should be kept in mind for psychiatric patients to ensure accurate diagnosis and optimal treatment options.Key PointsADHD is considerably underdiagnosed in the psychiatric populationGender ratios between 1.8:1 and 1:2.5 (male:female) reported in researchMore research is needed to ascertain if the use of ADHD screening instruments would improve the recognition and treatment of adult ADHD in the psychiatric population.

Feasibility and Acceptability of an Internet-Based Intervention for Young Adults with ADHD

Internet-based interventions (IBIs) to treat psychological disorders are available, but accessibility to these to treat attention-deficit/hyperactivity disorder (ADHD) in young adult populations is quite limited. The current study examined the feasibility of a proposed IBI for ADHD and participant perceptions regarding treatment acceptability and credibility, and outcome expectancy. Participants (N = 235; aged 18-35) with a prior ADHD diagnosis were recruited through Amazon's Mechanical Turk (MTurk) and were provided with a proposed IBI and explanatory outlines of treatment module content. Participants in the cross-sectional study were randomly assigned to either a tailored (i.e., targeted content modules), minimal (i.e., presented overall fewer and non-targeted modules), or full (i.e., all possible modules) condition. Results demonstrated moderate IBI acceptability among participants in the tailored and full conditions. The majority of participants preferred IBI over face-to-face (F2F) treatment, and most individuals who preferred F2F treatment also considered an IBI to be an acceptable treatment modality. Lack of significant mean differences between the tailored and full conditions on several of the main outcomes of interest (e.g., perceptions of acceptability) suggests that implementation of either method of treatment could prove effective. Differences based on treatment length and relevance, and biological sex were also explored. Implications, limitations, and future directions are discussed.

Emotional Status and Quality of Life in Women With ADHD During COVID-19

COVID-19 affects emotional status and quality of life (QOL) as reported in various countries. Less is known about the relations between gender, emotional status, and QOL in vulnerable groups. The objectives of this study is to compare emotional status and QOL between women with and without ADHD, during COVID-19, to correlate between emotional status, daily life, and QOL of women with ADHD, and to predict their QOL by COVID-19 constraints and emotional status. This cross-sectional online survey included 46 with ADHD and 183 typically functioning women, aged 19 to 60, who completed the sociodemographic-health and daily life during COVID-19 questionnaires; the Depression, Anxiety, and Stress Scale - 21, and the WHOQOL-BREF. Women with ADHD had significantly higher stress and anxiety and lower physical and psychological QOL. Emotional status and daily constraints predicted their QOL. COVID-19 emotional impacts should receive greater attention in vulnerable groups, as women with ADHD, to enhance resilience, participation, and QOL.

Associations Between Neonatal Brain Structure, the Home Environment, and Childhood Outcomes Following Very Preterm Birth

Background

Very preterm birth is associated with an increased risk of childhood psychopathology and cognitive deficits. However, the extent to which these developmental problems associated with preterm birth are amenable to environmental factors or determined by neurobiology at birth remains unclear.

Methods

We derived neonatal brain structural covariance networks using non-negative matrix factorization in 384 very preterm infants (median gestational age [range], 30.29 [23.57–32.86] weeks) who underwent magnetic resonance imaging at term-equivalent age (median postmenstrual age, 42.57 [37.86–44.86] weeks). Principal component analysis was performed on 32 behavioral and cognitive measures assessed at preschool age (n = 206; median age, 4.65 [4.19–7.17] years) to identify components of childhood psychopathology and cognition. The Cognitively Stimulating Parenting Scale assessed the level of cognitively stimulating experiences available to the child at home.

Results

Cognitively stimulating parenting was associated with reduced expression of a component reflecting developmental psychopathology and executive dysfunction consistent with the preterm phenotype (inattention-hyperactivity, autism spectrum behaviors, and lower executive function scores). In contrast, a component reflecting better general cognitive abilities was associated with larger neonatal gray matter volume in regions centered on key nodes of the salience network, but not with cognitively stimulating parenting.

Conclusions

Our results suggest that while neonatal brain structure likely influences cognitive abilities in very preterm children, the severity of behavioral symptoms that are typically observed in these children is sensitive to a cognitively stimulating home environment. Very preterm children may derive meaningful mental health benefits from access to cognitively stimulating experiences during childhood.

Neuropsychological functioning of individuals at clinical evaluation of adult ADHD

OBJECTIVES

Numerous studies showed that adults with attention deficit hyperactivity disorder (ADHD) suffer from impairments in a range of cognitive functions when compared to healthy controls. However, only little is known about the neuropsychological functions when compared to various clinical control groups and whether a distinct neuropsychological profile can be identified for adult ADHD.

METHOD

This retrospective study examined data of 199 outpatients referred for clinical evaluation of adult ADHD, allocated either to an ADHD group (n = 78) or to one of two clinical comparison groups, depending on whether they show indications (n = 71) or no indications (n = 50) for the presence of psychiatric disorders other than ADHD. All individuals performed a comprehensive neuropsychological test battery.

RESULTS

Data analysis revealed impairments in a range of cognitive functions in a substantial number of patients of all three groups. However, profiles of neuropsychological impairments were similar between groups. Furthermore, significant small- to medium-sized correlations between basic and higher-order cognitive functions were revealed in the ADHD group and the clinical comparison group with indications for psychiatric disorders other than ADHD.

CONCLUSION

Neuropsychological impairments are prominent in psychiatric outpatients seeking a clinical evaluation of adult ADHD but are not specific for ADHD. It is concluded that neuropsychological test performance may have limited incremental value to support the psychiatric differential diagnosis. Furthermore, a clinical trajectory may need to take into account that deficits in a range of higher-order cognitive functions can be substantially explained by deficits in basic cognitive functions.

Assessment of cytokines, microRNA and patient related outcome measures in conversion disorder/functional neurological disorder (CD/FND): The CANDO clinical feasibility study

BACKGROUND

Conversion disorder/functional neurological disorder (CD/FND) occurs often in neurological settings and can lead to long-term distress, disability and demand on health care services. Systemic low-grade inflammation might play a role, however, the pathogenic mechanism is still unknown.

AIM

1) To explore the feasibility to establish and assess a cohort of CD/FND with motor symptoms, involving persons with lived experience (PPI). 2) To generate proof of concept regarding a possible role for cytokines, microRNA, cortisol levels and neurocognitive symptoms in patients with motor CD/FND.

METHOD

Feasibility study.

RESULTS

The study showed active involvement of patients despite high clinical illness burden and disability, neurocognitive symptoms, childhood adverse experiences (ACE) and current life events. The study provided valuable knowledge regarding the feasibility of conducting a study in these patients that will inform future study phases. In the sample there were elevated levels of IL6, IL12, IL17A, IFNg, TNFa and VEGF-a, suggesting systemic low-grade inflammation. Also, microRNAs involved in inflammation and vascular inflammation were correlated with TNFa and VEGFa respectively, suggesting proof of concept for an epigenetic mechanism. Owing to the COVID-19 outbreak, the patient sample was limited to 15 patients.

CONCLUSION

It is a novelty that this study is conducted in the clinical setting. This innovative, translational study explores stress-related SLI in CD/FND patients and the feasibility of a larger project aiming to develop new treatments for this vulnerable population. Given the positive findings, there is scope to conduct further research into the mechanism of disease in CD/FND.

The role of stress coping strategies for life impairments in ADHD

Attention-deficit/hyperactivity disorder (ADHD) is commonly accompanied by functional impairments within personal, professional, and social context as well as further psychological distress. The role of perceived stress has been examined in this regard, although little is known about the influence of stress coping strategies. We examined the dynamics between ADHD symptomatology, stress coping strategies, and life impairments in a sample of 230 clinical and non-clinical adult individuals. ADHD was associated with low probability of choosing adaptive but high probability of implementing maladaptive stress coping strategies as well as with increased life impairments. Adaptive stress coping showed little effects beyond the associations between ADHD and life impairments, whereas some maladaptive coping strategies increased current life impairments over and above the effects of ADHD and further psychological distress. The present findings emphasize the need of professional support in adults with ADHD and the necessity to include stress coping strategies in respective treatment approaches aimed at reducing life impairments.

Association of psychiatric comorbidities with the risk of transport accidents in ADHD and MPH

AIMS

Although the relationship between attention-deficit/hyperactivity disorder (ADHD) and transport accidents has been shown, there is limited information on the relationship between medication and dose-response effects and transport accident risk. This study aims to determine whether young people with ADHD, including adolescents, are more prone to transport accidents than those without, and the extent to which methylphenidate (MPH) prescription in these patients reduces the risk.

METHODS

We identified 114 486 patients diagnosed with ADHD from Taiwan's National Health Insurance Research Database from 1997 to 2013. Using a Cox regression model, we compared the risk of transport accidents between ADHD and non-ADHD groups and estimated the effect of MPH on accidents. Furthermore, we applied a self-control case-series analysis to compare the risk of accidents during the medication periods with the same patients' non-medication periods.

RESULTS

Male ADHD patients had a higher risk of transport accidents than non-ADHD individuals (adjusted hazard ratio [aHR] = 1.24, [95% confidence interval (CI) 1.10-1.39]), especially for those comorbid with epilepsy, oppositional defiant disorder/conduct disorder (ODD/CD), and intellectual disabilities (ID). Female ADHD patients showed no relationship, except for comorbid with autism spectrum disorder (ASD) or ID. We found a reduced risk of transport accidents in patients with ADHD with MPH medication than those without MPH, with a plausible dose-response relationship (aHR of 0.23 to 0.07). A similar pattern was found in self-controlled case-series analysis.

CONCLUSIONS

Male patients with ADHD, especially those comorbid with epilepsy, ODD/CD, or ID, were at high risk of transport accidents. Female patients, when comorbid with ASD or ID, also exhibited a higher risk of accidents. MPH treatment lowered the accident risk with a dose-response relationship.

Updates in technology-based interventions for attention deficit hyperactivity disorder

PURPOSE OF REVIEW

Technological advancement has led to the development of novel treatment approaches for attention deficit hyperactivity disorder (ADHD). This review aims to review recent studies which employ the use of technology to treat ADHD, with particular focus on studies published during a 1-year period from February 2019 to February 2020.

RECENT FINDINGS

Most recent studies involved children aged 12 years and below. Interventions included cognitive training through games, neurofeedback and a combination of several approaches. More novel approaches included trigeminal nerve stimulation and brain-computer interface, and studies had utilized technology such as X-box Kinect and eye tracker. There was a shift towards delivering intervention at home and in school, enabled by technology. The study outcomes were variable and mainly included executive functioning measures and clinical ratings. These interventions were generally safe with few reported adverse events.

SUMMARY

Technology has enabled interventions to be delivered outside of the clinic setting and presented an opportunity for increased access to care and early intervention. Better quality studies are needed to inform on the efficacy of these interventions.

The Positive Aspects of Attention-Deficit/Hyperactivity Disorder among Famous People

OBJECTIVE

The shortage of clinical data regarding adult patients with often results in adults with ADHD being stigmatized and being inadequately treated. In this paper, famous people who potentially have ADHD were analyzed to understand better, the life-long progression of ADHD.

METHODS

131 people were analyzed as potential candidates for ADHD. A grading system for the candidates was developed: class 1, compatible with ADHD; class 2, likely; class 3, less likely; class 4, uncertain with a shortage of data; and class 5, not compatible. Initially, 39 subjects in class 4 and 12 in class 5 were excluded from the analysis. Finally, 80 subjects (30 in class 1, 33 in class 2, and 17 in class 3) were analyzed for sociodemographic data and psychiatric comorbidities.

RESULTS

88.8% were men and 47.5% of the subjects were married once. In terms of occupation, 45.0% of the subjects were cultural professionals and 25.0% were chief executives. Narcissistic personality disorder was the most frequently noted comorbidity, followed by substance-related and addictive disorder.

CONCLUSION

Famous people with ADHD in this study revealed high skill levels in occupation, offering positive aspects of ADHD in adults.

Psychometric properties of the Teenage Executive Functioning Inventory (TEXI): A freely available questionnaire for assessing deficits in working memory and inhibition among adolescents

The Childhood Executive Functioning Inventory (CHEXI) and the Adult Executive Functioning Inventory (ADEXI) are reliable and valid rating instruments for assessing working memory and inhibitory control. However, a teenage version of this instrument has not been available, and the aim of the present study was therefore to investigate the psychometric properties of the Teenage Executive Functioning Inventory (TEXI). After interviewing both researchers/clinicians and adolescents themselves, a questionnaire with 20 items was created. Data from adolescents age 13-19 years (n = 302) and their parents were thereafter collected. Factor analysis showed that the TEXI has two clear factors: working memory and inhibition. Further, the TEXI was shown to have high reliability in terms of internal consistency (≥ .85), split-half reliability (≥ .81) and inter-rater reliability between self-ratings and parent ratings (.82). In sum, the TEXI is a reliable questionnaire for measuring working memory and inhibition in adolescents. The two versions of the TEXI are presented in the appendices of this paper and they will be freely available on the Internet.

Intellectual functioning in Silver-Russell syndrome: First study in adults

Silver-Russell syndrome (SRS) is a rare genetic disorder (estimated incidence 1/30,000 to 100,000 live births). So far, only a few studies have focused on the cognitive profile of individuals with SRS, and these were conducted some time ago, concentrated on pediatric cohorts, and included patients who had been diagnosed using a variety of clinical diagnostic systems. There has yet to be any research on the intellectual functioning of adults with SRS. This study sought to establish the intelligence, strengths and weaknesses within intellectual profile of adults with SRS, compared with normative data. Ten individuals with 11p15 epimutation aged 18-39 years completed the Wechsler Adult Intelligence Scale-Fourth Edition. Measures of interest included participants' intelligence (Full Scale Intelligence Quotient [FSIQ]) and four domains of cognitive functioning: verbal comprehension, perceptual reasoning, working memory and processing speed. Discrepancy scores were calculated, and descriptive statistical and linear correlations were used to investigate factors associated with IQ outcome. Clinical and medical information such as rehabilitation, and perceived difficulties in daily life were collected by interviews and questionnaires. Results showed that the mean FSIQ score was in the average range (M = 95.40, SD = 18.55) and they performed best on verbal comprehension. Frequent daily difficulties were reported by patients and/or their families: learning disabilities and low self-esteem were perceived by 60% of adults. Early intervention and multidisciplinary care from childhood to adulthood are important in SRS for care potential medical, cognitive and psychosocial problems. This is the first study to document the intellectual functioning of adults with SRS.
