Evolving Adult ADHD Care: Preparatory Evaluation of a Prototype Digital Service Model Innovation for ADHD Care. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:582. [PMID: 38791796 PMCID: PMC11121032 DOI: 10.3390/ijerph21050582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 04/10/2024] [Accepted: 04/14/2024] [Indexed: 05/26/2024]
Abstract
BACKGROUND Given the prevalence of ADHD and the gaps in ADHD care in Australia, this study investigates the critical barriers and driving forces for innovation. It does so by conducting a preparatory evaluation of an ADHD prototype digital service innovation designed to help streamline ADHD care and empower individual self-management. METHODS Semi-structured interviews with ADHD care consumers/participants and practitioners explored their experiences and provided feedback on a mobile self-monitoring app and related service innovations. Interview transcripts were double coded to explore thematic barriers and the enablers for better ADHD care. RESULTS Fifteen interviews (9 consumers, 6 practitioners) revealed barriers to better ADHD care for consumers (ignorance and prejudice, trust, impatience) and for practitioners (complexity, sustainability). Enablers for consumers included validation/empowerment, privacy, and security frameworks, tailoring, and access. Practitioners highlighted the value of transparency, privacy and security frameworks, streamlined content, connected care between services, and the tailoring of broader metrics. CONCLUSIONS A consumer-centred approach to digital health service innovation, featuring streamlined, private, and secure solutions with enhanced mobile tools proves instrumental in bridging gaps in ADHD care in Australia. These innovations should help to address the gaps in ADHD care in Australia. These innovations should encompass integrated care, targeted treatment outcome data, and additional lifestyle support, whilst recognising the tensions between customised functionalities and streamlined displays.

[PMID: 38791781 PMCID: PMC11121453 DOI: 10.3390/ijerph21050566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 04/17/2024] [Accepted: 04/23/2024] [Indexed: 05/26/2024]
Abstract
(1) Objectives: This study aimed to assess the 5-year prevalence and clinical profile of attention deficit hyperactive disorder (ADHD) among adult patients seeking care in a tertiary care hospital in Oman. (2) Methods: The data were analysed using descriptive and inferential statistics and standardised prevalence estimates were calculated. (3) Results: Of the 39,881 hospital visits, 1.77% were made by adults with ADHD. This is equivalent to 17.8 visits per 1000 outpatients. The year 2021 saw the highest prevalence among the five years considered, while 2020 had the lowest prevalence. Although the age distribution indicated that the age group 'under 20' had the highest prevalence, the gender distribution showed that ADHD was more common among adult men. Among the various subtypes of ADHD, inattention was the most common. (4) Conclusions: This study specifically compared the prevalence and associated factors between an adult cohort with ADHD and those other psychiatric clinic attendees during the same period. The study offers important information on the prevalence and clinical profile of adults with ADHD in the population under consideration.

Abstract
OBJECTIVES To determine and compare the prevalence of attention deficit hyperactivity disorder (ADHD) symptoms among male and female medical students in the Eastern Province of Saudi Arabia and evaluate the effect of ADHD on the academic performance of the affected medical students. METHODS This cross-sectional study measured the prevalence of adult ADHD symptoms among medical students in the Eastern Province of Saudi Arabia. A total of 354 Saudi medical students from King Faisal University, Al-Ahsa, and Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia, participated in a self-reported questionnaire. The questionnaire was distributed on different social media platforms from December 2021 to April 2022. RESULTS Among the study participants, 26% exhibited symptoms highly consistent with adult ADHD. Young age (<20 years, p=0.049) and non-marital status (p=0.048) were associated with a higher rate of ADHD symptoms with recorded statistical significance. Additionally, there is no significant association between grade point average and adult ADHD (p=0.560). CONCLUSION The study demonstrated a higher prevalence of adult ADHD among medical students in the Eastern Province than the reported rates locally and globally. This could be attributed to social and cultural factors, as well as the chosen method for assessing the symptoms of Diagnostic and Statistical Manual items.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVE To examine the effects of triple beaded mixed amphetamine salts (TB MAS) on ADHD and executive dysfunction symptoms throughout the day in adults with DSM-5 ADHD. METHOD This was a 6 week, single-blind, placebo-lead in trial of TB MAS (12.5-37.5 mg/day); all participants received 2 weeks of single-blind placebo); one individual was a placebo responder and was discontinued. One of these 18 dropped after 1 week on 12.5 mg/day, while all others completed the trial and received 37.5 mg/day TB MAS. RESULTS There were significant effects of TB MAS on all clinical measures, including investigator overall symptoms (AISRS); self-report overall (ASRS), time-sensitive ADHD (TASS) scores throughout the day, impairment (CGI) and executive function scores (BRIEF-A). TB MAS was generally well tolerated. CONCLUSIONS This study extends prior findings of TB MAS to adults with DSM-5 ADHD; it further re-validates findings of efficacy of TB MAS throughout the day.

Abstract
Even though the number of studies aiming to improve comprehension of ADHD pathology has increased in recent years, there still is an urgent need for more effective studies, particularly in understanding adult ADHD, both at preclinical and clinical levels, due to the increasing evidence that adult ADHD is highly distinct and a different entity from childhood ADHD. This review paper outlines the symptoms, diagnostics, and neurobiological mechanisms of ADHD, with emphasis on how adult ADHD could be different from childhood-onset. Data show a difference in the environmental, genetic, epigenetic, and brain structural changes, when combined, could greatly impact the behavioral presentations and the severity of ADHD in adults. Furthermore, a crucial aspect in the quest to fully understand this disorder could be through longitudinal analysis. In this way, we will determine if and how the pathology and pharmacology of ADHD change with age. This goal could revolutionize our understanding of the disorder and address the weaknesses in the current clinical classification systems, improving the characterization and validity of ADHD diagnosis, specifically those in adults.

Abstract
OBJECTIVE The current study aims to examine the efficacy of an add-on dialectical behavior therapy skills training (DBT-ST) on adult attention-deficit/hyperactivity disorder (ADHD). The DBT-ST was applied online under the pandemic conditions that occurred after the study had started. METHODS The current randomized controlled trial consists of an intervention group to whom the DBT-ST was applied in online setting and a waitlist control group who received treatment as usual (TAU). Data were collected pre-, post-, and mid-treatment. ADHD symptoms (with the sub-dimensions of inattention and hyperactivity), impulsivity, mindfulness, difficulty with emotion regulation, interpersonal effectiveness, distress tolerance, life satisfaction, functionality in daily life, and general psychological symptom levels were measured with self-report scales. The data were analyzed using mixed-design ANOVA. RESULTS The global ADHD, inattention, and hyperactivity symptoms of the DBT-ST group significantly decreased more than those in the TAU control group. The DBT-ST group also showed a significant decrease regarding difficulty with emotion regulation and increases in life satisfaction and functionality, though the group × time effect was not significant. CONCLUSION DBT-ST was found effective against the participants' ADHD symptoms. The treatment was additionally found to improve their emotion regulation and quality of life. Further investigation is needed to investigate DBT-ST in an online setting.

Abstract
OBJECTIVE Studies show adult ADHD presents differently in men and women, however few studies contrast ADHD in cisgender and gender diverse adults. We assessed care differences between these groups using previously identified quality measures (QMs). METHODS Using EHR data, we matched a group of male ADHD patients to a female group. We followed the same procedure with a cisgender group and one identified as gender diverse through a gender dysphoria diagnosis. QM achievement was measured using logistic regression models. RESULTS Most QMs exhibited increasing achievement over time for all groups. Variations in care quality between males and females persisted, with female patients achieving QMs more often. There were no appreciable differences between the cisgender and gender diverse groups. CONCLUSION Though quality care for adult ADHD improved from 2010 to 2020, differences between male and female patients lingered. This effect was not observed in cisgender and gender diverse patients.

Abstract
OBJECTIVE We analyzed adult ADHD symptoms in a cross-cultural context, including investigating the occurrence and potential correlates of adult ADHD and psychometric examination of the Adult ADHD Self-Report Scale (ASRS) Screener. METHOD Our analysis is based on a large-scale research project involving 42 countries (International Sex Survey, N=72,627, 57% women, Mage=32.84; SDage=12.57). RESULTS The ASRS Screener demonstrated good reliability and validity, along with partial invariance across different languages, countries, and genders. The occurrence of being at risk for adult ADHD was relatively high (21.4% for women, 18.1% for men). The highest scores were obtained in the US, Canada, and other English-speaking Western countries, with significantly lower scores among East Asian and non-English-speaking European countries. Moreover, ADHD symptom severity and occurrence were especially high among gender-diverse individuals. Significant associations between adult ADHD symptoms and age, mental and sexual health, and socioeconomic status were observed. CONCLUSIONS Present results show significant cross-cultural variability in adult ADHD occurrence as well as highlight important factors related to adult ADHD. Moreover, the importance of further research on adult ADHD in previously understudied populations (non-Western countries) and minority groups (gender-diverse individuals) is stressed. Lastly, the present analysis is consistent with previous evidence showing low specificity of adult ADHD screening instruments and contributes to the current discussion on accurate adult ADHD screening and diagnosis.

Abstract
OBJECTIVE This study aims to investigate the factors influencing medication adherence among adults with Attention-Deficit/Hyperactivity Disorder (ADHD) and impact of central nervous system stimulants (CNS) adherence on healthcare utilization (HCU). Methods: This was a cross-sectional study using Medical Expenditure Panel Survey 2013 to 2019, with participants (≥18 years of age) with ADHD and had at least one CNS prescription. Multivariate logistic and linear regression were utilized to evaluate the medication adherence and its impact on HCU, respectively. RESULT Total 798 (10,718,005 weighted) ADHD patients, were mostly White (81%), aged between 18 and 25 (35%), and non-adherent to CNS (65%). The use of extended-release medications (OR = 1.51 [1.03, 2.23]) and new users (OR = 3.46 [2.12, 5.63], p ≤ .05) were positively associated with medication adherence. The adherent group utilized more outpatient visits (0.04 vs. 0.46) and prescription refills (18.38 vs. 31.25) compared to non-adherent. CONCLUSION Our findings can be applied to improve the medication adherence, patient education, and optimize intervention for adults with ADHD.

Abstract
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.

Abstract
Background Attention-deficit/hyperactivity disorder (ADHD) is a neuro-developmental disorder prevalent among children and adults. Adults living with ADHD can experience significant distress affecting their daily functioning on emotional, physical, interpersonal, familial and financial levels. Intervention programmes may be a way to mitigate these challenges. Aim This review identified good evidence-based intervention studies for adults with ADHD and described the usefulness of these interventions. Method Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, articles were searched from 2009 to 2019 across four medical- and psychological-focused electronic databases using EBSCOhost. All articles selected for the review's thematic meta-synthesis were appraised by attaining a threshold score of at least 61%, using the Smith-Franciscus-Swartbooi appraisal tool. Two autonomous reviewers engaged in the review process. The study adhered to all ethical principles pertaining to systematic review practice. Results Forty studies were identified for summation, including pharmacological, non-pharmacological and neuro-stimulation approaches. Most interventions used a multimodal approach. Results indicated the most effective stimulant and non-stimulant as methylphenidate and atomoxetine, respectively. Effective non-pharmacological approaches to treatment were identified as cognitive-behavioural treatment, mindfulness-based approaches, psycho-education and dialectical-focused therapies. Bright light treatment and neurofeedback were reported as the most efficacious neuro-stimulatory methods. Conclusion Pharmacological and non-pharmacological approaches, as well as neuro-stimulation or a blend of these approaches were acknowledged as the most effective recent modalities in the treatment of adult ADHD. Contribution This review reported on the most current approaches to treat adult ADHD. This will facilitate a better understanding and informed decisions with regard to dealing with adult ADHD.

Abstract
(1) Background: The clinical assessment of attention-deficit/hyperactivity disorder (ADHD) in adulthood is known to show non-trivial base rates of noncredible performance and requires thorough validity assessment. (2) Objectives: The present study estimated base rates of noncredible performance in clinical evaluations of adult ADHD on one or more of 17 embedded validity indicators (EVIs). This study further examines the effect of the order of test administration on EVI failure rates, the association between cognitive underperformance and symptom overreporting, and the prediction of cognitive underperformance by clinical information. (3) Methods: A mixed neuropsychiatric sample (N = 464, ADHD = 227) completed a comprehensive neuropsychological assessment battery on the Vienna Test System (VTS; CFADHD). Test performance allows the computation of 17 embedded performance validity indicators (PVTs) derived from eight different neuropsychological tests. Further, all participants completed several self- and other-report symptom rating scales assessing depressive symptoms and cognitive functioning. The Conners' Adult ADHD Rating Scale and the Beck Depression Inventory-II were administered to derive embedded symptom validity measures (SVTs). (4) Results and conclusion: Noncredible performance occurs in a sizeable proportion of about 10% up to 30% of individuals throughout the entire battery. Tests for attention and concentration appear to be the most adequate and sensitive for detecting underperformance. Cognitive underperformance represents a coherent construct and seems dissociable from symptom overreporting. These results emphasize the importance of performing multiple PVTs, at different time points, and promote more accurate calculation of the positive and negative predictive values of a given validity measure for noncredible performance during clinical assessments. Future studies should further examine whether and how the present results stand in other clinical populations, by implementing rigorous reference standards of noncredible performance, characterizing those failing PVT assessments, and differentiating between underlying motivations.

Abstract
Historically, attention-deficit hyperactivity disorder (ADHD) was conceptualised as a disorder of childhood that gradually improved and diminished as individuals transitioned to adulthood. Over the past decade, several studies have been published describing a cohort of adolescents with a childhood diagnosis of ADHD experiencing a continuity of ADHD symptoms into adulthood. Untreated ADHD in adults is associated with personal relationship difficulties, educational and occupational underachievement, comorbid mental health problems, substance misuse, and increased rates of road traffic accidents and criminality. These result in an increased economic burden and broader public health challenges. This review outlines the current framework and stage of development of ADHD services for adults in the Republic of Ireland.

Abstract
Introduction Mental restlessness reported by adult with Attention Deficit Hyperactivity Disorder (ADHD) has been mainly explained by excessive mind wandering. However, the description of a mind constantly on the go is also akin to racing thoughts, predominantly described in bipolar disorder. This paper aimed at disentangling mind wandering from racing thoughts in adult with ADHD. Associations between those mental phenomena and the ADHD symptomatology were also investigated. Methods To this aim, 84 adults with ADHD completed self-reported questionnaires, including the Mind Wandering-Deliberate and Mind Wandering-Spontaneous questionnaires, the Racing and Crowded Thoughts Questionnaire and the Daydreaming Frequency Scale. Factorial analysis and multiple linear regressions were performed. Results The factor analysis yielded a two-factor solution. The first factor encompassed the three facets of racing thoughts and was predicted by emotional lability. The second comprised deliberated-MW, spontaneous-MW and daydreaming, but was neither related to the ADHD symptoms, nor functional impairment. Discussion These findings suggest that MW and racing thoughts are two distinguishable mental phenomena. Racing thoughts appear to be a relevant hypothesis to explain the mental restlessness in adult ADHD.

Abstract
OBJECTIVE Understanding the association between polygenic risk for ADHD and cognition throughout aging has not been widely studied. This study aimed to determine whether ADHD risk influences cognitive performance among individuals at both young-old and middle-old age. METHOD Participants from the Health and Retirement Study, a biennial survey of 20,000 Americans, were compared on executive function and delayed recall measures using regression analyses. RESULTS There was no significant effect of ADHD risk on memory at both age waves for African-ancestry (AA; n = 403) and European-ancestry (EA; n = 2,286). There was, however, a significant association between ADHD risk and performance on executive function for EA at middle-old age (p = .028), but not young-old age; no such association was observed for AA adults. CONCLUSION This finding suggests that ADHD risk may differentially influence cognition among older adults throughout the aging process, with important implications for future research.

Abstract
Introduction Oral dysesthesia is a disease characterized by pain and/or abnormal sensations in the oral region, without any organic abnormality. Its symptoms include pain, and it is considered to be a disorder associated with idiopathic oral-facial pain. It is also known that idiopathic oral-facial pain tends to coexist with chronic musculoskeletal pain, including low back pain, even before its onset. Such coexisting idiopathic pain conditions are also called chronic overlapping pain conditions (COPCs). In general, COPCs are often refractory to treatment. Recently, it has been reported that attention deficit hyperactivity disorder (ADHD) is associated with many COPCs, such as pain in the facial and lower back regions and so on. However, there are no reports of (1) ADHD as a comorbidity with oral dysesthesia (OD) or (2) of the therapeutic effects of ADHD medications or dopamine agonists on low back pain and OD or an (3) evaluation of cerebral blood flow over time after treatment with these medications for OD and low back pain. Case Presentation In this study, we report the case of an 80-year-old man with OD and chronic low back pain that persisted for more than 25 years. His OD and chronic back pain were refractory to standard treatment, prevented him from continuing work, and tended to be exacerbated by conflicts in his relationship with his son. In recent years, ADHD has often been found to be comorbid with chronic pain, and ADHD medications have been reported to improve chronic pain as well. The patient was confirmed to have undiagnosed ADHD and was treated with the ADHD medication atomoxetine and dopamine agonist pramipexole, which dramatically improved his OD, chronic back pain, and cognitive function. Furthermore, along the course of treatment, there was improvement in cerebral blood flow in his prefrontal cortex, which was thought to reflect improved function in the region. Consequently, he was able to resume work and improve his family relationships. Conclusion Therefore, in the cases of ODs and COPCs, screening for ADHD and, if ADHD is diagnosed, ADHD medications or dopamine agonists may be considered.

Abstract
OBJECTIVE Self-report symptom inventories are commonly used in adult ADHD assessment, and research indicates they should be interpreted with caution. This study investigated one self-report symptom inventory for adult ADHD in a clinical sample. METHOD Archival data were used to evaluate diagnostic utility of the Conners Adult ADHD Rating Scale-Self-Report: Long Version (CAARS-S:L) in a sample of 122 adults seeking ADHD assessment. RESULTS Overall, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) estimates for the ADHD Index and other CAARS-S:L scales demonstrated weak accuracy. Anxiety and depression were the most common diagnoses present when a false positive on the ADHD Index was observed. PPV and specificity for the ADHD Index were higher in males compared to females. CONCLUSION The CAARS-S:L may be useful for screening purposes in some cases, but should not be the main method used for diagnostic purposes. Clinical implications of findings are discussed.

Abstract
INTRODUCTION The short version of the Conners' Adult ADHD Rating Scales (CAARS-S:S) is a self-report measure used to identify symptoms of Attention Deficit/Hyperactivity Disorder (ADHD) during adulthood. However, its psychometric properties specifically in emerging adults, or the transitional age group between adolescence and adulthood, remain understudied. This study aimed to validate the factor structure of the CAARS-S:S in a sample of emerging adults. METHOD The CAARS-S:S measure was completed by adults (n = 591) aged 18 to 29 located in English-speaking countries, including Australia, Canada and the United States. Confirmatory factor analysis was used to test a four-factor model of Inattention/Memory Problems, Hyperactivity/Restlessness, Impulsivity/Emotional Lability and Problems with Self-Concept, as well as the model's invariance by sex. Sex was also included as a covariate in the model to examine differences in males' and females' scores on each factor. RESULTS Overall, the four-factor structure fit the data and was invariant across males and females. All factors demonstrated high internal reliability (average ωt and α = .86). It was observed that males tended to score higher on Inattention/Memory Problems while females scored higher on Problems with Self-Concept. CONCLUSION This research establishes the psychometric properties of the CAARS-S:S, placing greater confidence in using it to screen for ADHD symptoms in emerging adults living in a Westernized cultural context. The detailed findings of this research, implications for the use of the CAARS-S:S in this age group and potential future directions for examining the properties of the measure are discussed.

Abstract
OBJECTIVE This study aimed to investigate ADHD in adult outpatients seeking treatment for a behavioral addiction and to identify the specificity of psychopathological features if the behavioral addiction cooccurs with adult ADHD. METHOD Sixty-five outpatients consulting for a behavioral addiction were assessed for ADHD (DIVA-5), addictive disorder (alcohol, tobacco, cannabis, gambling, gaming, food, and sex), impulsivity (UPPS-P), and emotion dysregulation (DERS-36). RESULTS In our sample of outpatients seeking treatment for a behavioral addiction, adult ADHD was independently associated with higher compulsive sexual behavior disorder severity, "sensation seeking," "positive urgency," difficulties in "goal-directed behavior," "impulse control," and use of "emotion regulation strategies" in the context of intense emotions. A 19% of the sample was diagnosed for adult ADHD. CONCLUSION The association of adult ADHD with specific dimensions of impulsivity and emotion dysregulation, pave the way for future clinical and research perspectives.

Abstract
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.

Abstract
Background: Non-stimulant guanfacine is a common second-line medication for attention-deficit hyperactivity disorder (ADHD). Numerous randomized controlled trials (RCTs) have explored the efficacy of guanfacine in ADHD treatment. This meta-analysis combined data from selected RCTs to analyze the efficacy and safety of guanfacine in treating ADHD. Methods: RCTs were identified from published sources through searches in PubMed, Cochrane Library, Web of Science, and Embase (up to February 2022), defining the Clinical Global Impression of Improvement (CGI-I) treatment response score of ≤2 as the primary outcome. Subgroup analysis was performed with a bound treatment duration of 10 weeks. Safety was defined by treatment-emergent adverse events (TEAEs). Results: Twelve out of 332 studies with 2653 participants were included. All studies compared guanfacine with placebos. Guanfacine was significantly more effective in treating ADHD (Risk Ratio [RR] 1.78, 95% CI: 1.59-2.01). In the <10 weeks subgroup, the efficacy in the guanfacine group compared with the placebo group was 58.5% versus 29.4%, respectively (RR 1.97, 95% CI: 1.71-2.26). In the >10 weeks subgroup, the efficacy in the guanfacine group compared with the placebo group was 63.6% versus 39.7%, respectively (RR 1.57, 95% CI: 1.37-1.79). Both subgroups lacked heterogeneity (I2 = 0), and a funnel plot showed a low publication bias risk. Around 80% of participants in the guanfacine group experienced at least one TEAE, compared with 66.5% in the placebo group (RR 1.23, 95% CI: 1.14-1.32), with low heterogeneity (I2 = 46, p = 0.05). The most common TEAEs in the guanfacine group were somnolence (38.6%), headaches (20.5%), and fatigue (15.2%). Conclusions: Guanfacine is safe and effective for treating ADHD, with no serious adverse events. Guanfacine should be considered as an effective treatment option where effectiveness or tolerability of the central nervous system stimulant is of concern. There is stronger evidence of efficacy for children; more clinical studies are needed for adults.

Abstract
This study cross-validated the dot counting test (DCT) as a performance validity test (PVT) in an adult attention-deficit/hyperactivity disorder (ADHD) clinical population and examined the effect of ADHD subtype and psychiatric comorbidity on accuracy for detecting invalidity. DCT performance was assessed among 210 consecutive adult ADHD referrals who underwent neuropsychological evaluation and were classified into valid (n = 175) or invalid (n = 35) groups based on seven independent criterion PVTs. The invalid group had significantly worse DCT performance than the valid group using both the standard and unrounded scoring procedure (ηp2=.28). Classification accuracy was excellent, with 54.3% sensitivity/92% specificity at optimal cut-scores of ≥14 (rounded) and ≥13.38 (unrounded). Nonsignificant DCT performance differences emerged based on ADHD subtype or the presence/absence of comorbid psychopathology. The DCT functions well as a nonmemory-based PVT in an ethnoracially diverse ADHD population, supporting its clinical utility for detecting invalid neurocognitive performance during ADHD evaluations.

Abstract
OBJECTIVE Polysomnographic findings in neurodevelopmental disorders have been reported, but previous studies have had several limitations. The purpose of this study was to characterize sleep structure in untreated adults diagnosed with ADHD, excluding ADHD-related sleep disorders as determined by polysomnography and multiple sleep latency testing. METHODS This study included 55 patients aged 18 years or older who visited the Kurume University Hospital Sleep Clinic between April 2015 and March 2020. The diagnosis of ADHD was determined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (ADHD group, n = 28; non-ADHD, n = 27). RESULTS The ADHD group had significantly longer slow wave sleep (SWS) duration than the non-ADHD group (ADHD: 68.3 ± 31.0 minutes vs. non-ADHD: 43.4 ± 36.6 minutes; p = .0127). CONCLUSIONS The increased SWS volume observed in drug-naïve adult patients with ADHD may be related to the pathogenesis of this disorder.

Abstract
OBJECTIVE Quality care for attention deficit hyperactivity disorder (ADHD) in adults has lagged behind other psychiatric disorders. We sought to assess how the achievement of quality measures (QMs) for diagnosing and treating ADHD in adults has changed over time. METHOD We assessed 10 QMs in electronic health records (EHRs) from primary care and behavioral health clinics from 2010 to 2020 for 71,310 patients diagnosed with ADHD. RESULTS The achievement of QMs increased over time (p < .001). Some showed increases to high levels; others remained low throughout the observation period. No patients achieved more than six of 10 QMs in any year. Small but significant effects for sex, race, ethnicity, practice ownership, practice type, and age. CONCLUSION Increase in quality care from 2010 to 2020 along with clear evidence that more efforts are needed to improve quality of care for adults with ADHD seen in primary care.

Abstract
Time perception is impaired in adult ADHD. Since the term time perception subsumes different constructs, including time estimation, time reproduction, time production, and duration discrimination, it remains open whether certain domains are more affected than other domains in adult ADHD. The aim of this explorative review is to present the current state of research on time perception in adult ADHD by analysing studies from the past 10 years. A review of the literature addressing adult ADHD time perception, time estimation, and time reproduction was performed. The search strategy was conducted by using the databases "PubMed", "Medline", and "PSYNDEX". The results of the present review indicate that the number of studies on time perception in adult ADHD is very scarce. Moreover, the main investigated domains of time perception in the past decade were time estimation, time reproduction and time management. Whereas some of the found studies were able to demonstrate a distinct deficit in time estimation, time reproduction and time management other studies were unable to demonstrate a clear association between ADHD and time estimation and time reproduction deficits. However, the diagnostic protocols, study design, and methodology varied between studies. Further studies on time estimation and time reproduction need to be carried out.

ADHD Follow-Up in Adulthood among Subjects Treated for the Disorder in a Child and Adolescent Mental Health Service from 1995 to 2015. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020338. [PMID: 36837537 PMCID: PMC9966311 DOI: 10.3390/medicina59020338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 02/03/2023] [Accepted: 02/06/2023] [Indexed: 02/12/2023]
Abstract
Background and Objectives: ADHD is a neurodevelopmental disorder characterized by inattention and hyperactivity/impulsivity and can persist in adulthood. The aim of this study is to deepen knowledge about adult ADHD follow-up. Materials and Methods: This observational study consists of one retrospective part aimed at collecting records of children and adolescents treated for ADHD in the Children and Adolescent Mental Health Service (CAMHS) from 1995 to 2015 and, successively, at identifying their adult follow-up in Adult Mental Health Service (AMHS); the second part consists of ADHD scale administration, Diagnostic Interview for ADHD in Adults (DIVA 2-0) and Adult Self Rating Scale (ASRSv1.1), for the subjects currently being treated at AMHS who agreed to participate in the study. Results: We observed that among the 55 patients treated at CAMHS between 1995 and 2015 for ADHD and subsequently at the AMHS, none presented a diagnosis of ADHD; instead, they were treated for Intellectual Dysfunction (33%), Borderline Personality Disorder (15%) and Anxiety Disorders (9%), and two individuals were also diagnosed with comorbid substance/alcohol abuse (4%). Of the 55 patients, only 25 (45%) were treated at AMHS during the study period. Though we asked for their informed consent to administer the questionnaires, we were able to test only seven patients. The ASRS-V1.1 score showed that 43% of patients reported symptoms of ADHD persistence in adulthood. For DIVA 2.0, 57% of individuals reported scores indicating the persistence of the ADHD inattention component, and 43% the persistence of both ADHD dimensions. Conclusions: ADHD cannot be considered a disorder confined to childhood/adolescence but instead is a chronic and complex condition that can persist into adulthood. The very small size of our final sample may account for both the high ADHD dropout rate over the long follow-up period and the difficult transition from child to adult health care in ADHD treatment. Our investigation suggests the need for specific training in the diagnosis and treatment of adult ADHD and the implementation of transition protocols between minor and adult services to improve long-term treatments.

Abstract
BACKGROUND ADHD is a common neurodevelopmental disorder frequently diagnosed between the ages 7 and 10 years. We measured ADHD symptomatology in a representative sample of the Czech population. MATERIAL AND METHODS Data collection was performed in January 2019 through the European National Panel. The respondents completed a demographic questionnaire focusing on ADHD history and a standardized questionnaire, the Adult ADHD Self-Report Scale (ASRS) screener for ADHD symptomatology in adulthood. RESULTS From the sample of 1,518 respondents, 3% of the respondents reported having been diagnosed with ADHD/hyperkinetic disorder in their lifetime. According to ASRS scoring, 119 respondents were classified as suspected ADHD. Overall, more males than females reported ADHD symptomatology. Age was also significantly associated with ASRS. Education status yielded no significant results. CONCLUSION Our study documents that the prevalence of ADHD symptomatology in adults is comparable with that in Western countries despite the different historical and health care backgrounds.

Abstract
OBJECTIVE To examine whether putatively atypical neuronal activity during internal attention in ADHD yields insights into processes underlying emotion dysregulation. METHODS We used a word processing paradigm to assess neural activations in adults with ADHD (N = 46) compared to controls (N = 43). We measured effects of valence, applied partial-least squares correlation analysis to assess multivariate brainbehavior relationships and ran subgroup analyses to isolate results driven by pure ADHD (N = 18). RESULTS During internal attention, ADHD, compared to controls, have (1) increased activation in the right angular gyrus (rAG), which appears driven by pure, not comorbid, ADHD and (2) diminished activation in the insula and fronto-striatal circuitry. Diminished activations were driven by negatively-valenced internal attention and negatively correlated with increased affective lability within the ADHD group. CONCLUSION Internal attention in ADHD is associated with increased rAG activation, possibly reflecting difficulty converging external and internal information, and diminished activation within emotion regulation circuitry.

Abstract
Screening for adult Attention-Deficit/Hyperactivity Disorder (ADHD) and differentiating ADHD from comorbid mental health disorders remains to be clinically challenging. A screening tool for ADHD and comorbid mental health disorders is essential, as most adult ADHD is comorbid with several mental health disorders. The current pilot study enrolled 955 consecutive patients attending a tertiary mental health center in Canada and who completed EarlyDetect assessment, with 45.2% of patients diagnosed with ADHD. The best ADHD classification model using composite scoring achieved a balanced accuracy of 0.788, showing a 2.1% increase compared to standalone ADHD screening, detecting four more patients with ADHD per 100 patients. The classification model including ADHD with comorbidity was also successful (balanced accuracy = 0.712). The results suggest the novel screening method can improve ADHD detection accuracy and inform the risk of ADHD with comorbidity, and may further inform specific comorbidity including MDD and BD.

Abstract
OBJECTIVE Children with ADHD often tend to underperform in school. This partial study aimed to find out if the school experience of adults with higher ADHD symptomatology differs from those with lower and no ADHD symptomatology. METHOD Based on the results of ASRS questionnaires, the respondents were divided into three groups (low, medium, and high) according to the manifested ADHD symptomatology. We explored their school experiences by looking at their grades for behavior at school, notes regarding their attendance, school expulsion, and other school experiences. RESULTS Children with higher ADHD symptomatology were significantly more likely to be expelled, receive notes for bad behavior, disturbing or forgetting as well as receive reprimands from teachers. CONCLUSION Our results show that children with increased ADHD symptomatology experience more difficulties with school behavior, they are frequently reprimanded, and they do receive more negative feedback regarding their attendance and tardiness from teachers.

Abstract
Almost 30% of ADHD adults do not respond to standard pharmaceuticals. Transcranial direct current stimulation (tDCS) is a method for modulation of cortical excitability. On the other hand, dialectical behavioral therapy (DBT) is a cognitive-behavioral approach that might be utilized for adults with ADHD. The effects of integration of these interventions are only beginning to be explored. In the present work, we used both subjective and objective measures to investigate the effects of tDCS, DBT, and the integration of the two in treating adult ADHD symptoms. A total of 80 adults with ADHD (63 females, 17 males) participated in the study and were grouped into control, DBT, tDCS, and combined groups. Based on the observed results, the combination of DBT and tDCS was significantly effective in improving the mentioned variables compared to administration of each method in isolation. The results are discussed in terms of neurophysiological and psychological aspects of treatment methods.

Abstract
OBJECTIVE To compare the effect of a once-daily extended-release methylphenidate formulation (PRC-063) versus placebo on sleep, measured via daily electronic diary in two clinical trials in pediatric (6-12 years) and adult (≥18 years) patients with attention deficit hyperactivity disorder (ADHD). METHOD A diary was completed by adult patients or parents/caregivers of pediatric patients during two randomized, double-blind, placebo-controlled laboratory classroom studies. Following dose optimization of PRC-063, patients were randomized to 1 week of double-blind treatment with PRC-063 or placebo before attending a full-day laboratory classroom session. RESULTS In the studies, 148 pediatric patients and 239 adult patients were randomized to either PRC-063 or placebo. When compared with the diaries of placebo patients, the sleep diaries in both pediatric and adult patients showed no statistical difference in total sleep time, efficiency, or latency. CONCLUSION PRC-063 did not impact subjective measures of sleep versus placebo in pediatric and adult patients with ADHD.

Stability of Attention Performance of Adults with ADHD over Time: Evidence from Repeated Neuropsychological Assessments in One-Month Intervals. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:15234.

Abstract
Neuropsychological assessments of attention are valuable sources of information in the clinical evaluation of adults with attention-deficit/hyperactivity disorder (ADHD). However, it is unclear whether the attention performance of adults with ADHD is stable or fluctuates over time, which is of great importance in the interpretation of clinical assessments. This study aimed to explore the stability of attention performance of adults with ADHD in repeated assessments at one-month intervals. Twenty-one adults diagnosed with ADHD took part in this study by completing selective attention and vigilance tests three times, each one month apart. Test scores of participants were compared with and interpreted based on test norms. A considerable proportion of 'below average' performance scores were observed in most of the variables of selective attention and vigilance in all three assessments. Further, selective attention and vigilance performance scores did not differ significantly between the three repeated assessments. Finally, the majority of participants received consistent test score interpretations across the three repeated assessments. This study confirms previous research and highlights abnormal selective attention and vigilance performance in adults with ADHD. Further, this study preliminarily demonstrates relatively stable attention performance across repeated assessments, which has the potential to support clinical assessment, treatment planning, and evaluation.

Abstract
The adult patient who presents for psychiatric evaluation with symptoms of attention deficit hyperactivity disorder (ADHD) poses specific challenges to the treating psychiatrist. Symptoms include trouble focusing, hyperactivity, and impulsive behavior. Patients may experience behavioral, mood, and cognitive issues. Co-occurrence of anxiety, boredom, sleep deprivation, or mood dysregulation may be reported. In addition, patients may have associated learning disabilities, either identified or undiagnosed. Symptoms can range from mild to severe. Many adults are unaware that they have ADHD, but they are acutely aware that they have everyday challenges. This article reviews the treatment dynamics created by the adult patient with a diagnosis of ADHD, as well as the evidence-based approaches that the psychiatrist can utilize in a psychotherapy setting.

Abstract
OBJECTIVE Continuous performance tests are widely used to aid diagnostic decision making and measure symptom reduction in adult ADHD clinical populations. The diagnostic accuracy of the Quantified Behavior Test plus (QbTest+), developed to identify ADHD populations as an objective measure of ADHD symptoms, was explored. METHODS The utility of the QbTest+ was investigated in a clinical cohort of 69 adult patients referred to a specialist ADHD clinic in the UK. RESULTS Scores from the QbTest+ failed to differentiate between patients diagnosed with ADHD and those who did not receive a diagnosis after full clinical assessment. CONCLUSIONS Based on our findings, we recommend clinicians are cautious when interpreting results of the QbTest+ in clinical populations. This study highlights the need for investigation into the lack of validation of commonly used objective measures in ADHD populations.

Abstract
This study applied network analysis to explore the relations between neuropsychological functions of individuals in the clinical evaluation of attention-deficit/hyperactivity disorder (ADHD) in adulthood. A total of 319 participants from an outpatient referral context, that is, 173 individuals with ADHD (ADHD group) and 146 individuals without ADHD (n-ADHD group), took part in this study and completed a comprehensive neuropsychological assessment. A denser network with stronger global connectivity was observed in the ADHD group compared to the n-ADHD group. The strongest connections were consistent in both networks, that is, the connections between selective attention and vigilance, and connections between processing speed, fluency, and flexibility. Further centrality estimation revealed attention-related variables to have the highest expected influence in both networks. The observed relationships between neuropsychological functions, and the high centrality of attention, may help identify neuropsychological profiles that are specific to ADHD and optimize neuropsychological assessment and treatment planning of individuals with cognitive impairment.

University Students' Sleep and Mental Health Correlates in South Korea. Healthcare (Basel) 2022; 10:healthcare10091635. [PMID: 36141246 PMCID: PMC9498813 DOI: 10.3390/healthcare10091635] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 08/22/2022] [Accepted: 08/24/2022] [Indexed: 11/17/2022] Open
Abstract
Sleep closely relates to emotional instability. Recent studies report an increase in young adults’ poor sleep and associated mental health problems, including attention deficit hyperactivity disorder (ADHD), anxiety, depression, and so on. However, the information on related modifiable factors of these variables is still lacking. This cross-sectional study examined the association of sleep patterns and sleep quality with ADHD and depression in university students. A total of 290 participants aged 18−27 (Mean = 22.0, SD = 2.1) completed a structured questionnaire consisting of the Pittsburgh Sleep Quality Index (PSQI), the Adult ADHD, and the Center for Epidemiologic Studies Depression scales (CES-D). Of the participants, more than half (52.7%) slept 6 to 8 h per night, and 37% slept less than 6 h. Only 10% reported they went to bed before midnight; 40% went to sleep after 2 am. The mean PSQI score was 5.9 (SD = 2.9) for total participants and significantly correlated with ADHD scores and with depression scores. After adjusting for covariates, PSQI significantly aligned with increased risk for ADHD (β = 0.29, p = 0.036) and depression (β = 0.67; p < 0.001). Late bedtime was a significant factor for depression only. Sleep quality rather than sleep pattern significantly related to ADHD scores, whereas both sleep quality and bedtime aligned with depression scores. Additional studies are needed to develop strategic interventions for university students with ADHD and depression as well as underlying mechanisms.

What adults with ADHD want to know: A Delphi consensus study on the psychoeducational needs of experts by experience. Health Expect 2022; 25:2593-2602. [PMID: 35999687 PMCID: PMC9615057 DOI: 10.1111/hex.13592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Revised: 08/08/2022] [Accepted: 08/12/2022] [Indexed: 11/30/2022] Open
Abstract
Introduction A lack of knowledge about attention‐deficit/hyperactivity disorder (ADHD) can contribute to feelings of distress and difficulty in seeking and accepting an ADHD diagnosis. The present study uses a Delphi consensus design to investigate the psychoeducational needs of adults with ADHD and the information about ADHD they would like included in digital health interventions for adults with ADHD. Inclusion of perspectives of service users in developing such interventions ensures that they are evidence based and addresses the risks of engagement barriers. Methods The expert panel consisted of 43 adults with ADHD (age range: 23–67 years). Panel members were asked to rate the importance of the proposed topics and provide additional suggestions. Suggested topics and topics that did not achieve consensus were included for ranking in the second round. Results Interquartile ratings were used to determine consensus. A high consensus was achieved in both rounds, with an agreement on 94% of topics in the first round and 98% in the second round. Most topics were rated as important or essential. Conclusions The findings highlighted that adults with ADHD want to learn about many different aspects of ADHD and the importance of considering their perspectives when developing psychosocial interventions. Findings can be applied when creating psychoeducational content for adult ADHD. Patient or Public Contribution Adults with ADHD were recruited to the Delphi panel to use an experts‐by‐experience approach. In doing so, we are engaging service users in the development of a psychoeducational smartphone app. The evaluation of the app will involve interviews with app users. Additionally, the present study was developed and conducted with ADHD Ireland, a charity based in Ireland that advocates for people with ADHD.

Abstract
OBJECTIVES Depression and ADHD often co-occur and are both characterized by altered attentional processing. Differences and overlap in the profile of attention to emotional information may help explain the co-occurence. We examined negative attention bias in ADHD as neurocognitive marker for comorbid depression. METHODS Patients with depression (n = 63), ADHD (n = 43), ADHD and depression (n = 25), and non-psychiatric controls (n = 68) were compared on attention allocation toward emotional faces. The following eye-tracking indices were used: gaze duration, number of revisits, and location and duration of first fixation. RESULTS Controls revisited the happy faces more than the other facial expressions. Both the depression and the comorbid group showed significantly less revisits of the happy faces compared to the ADHD and the control group. Interestingly, after controlling for depressive symptoms, the groups no longer differed on the number of revisits. CONCLUSION ADHD patients show a relative positive attention bias, while negative attention bias in ADHD likely indicates (sub)clinical comorbid depression.

Neural Correlates of Reactive Aggression in Adult Attention-Deficit/Hyperactivity Disorder. Front Psychiatry 2022; 13:840095.

Abstract
Despite not being part of the core diagnostic criteria for attention-deficit/hyperactivity disorder (ADHD), emotion dysregulation is a highly prevalent and clinically important component of (adult) ADHD. Emotionally dysregulated behaviors such as reactive aggression have a significant impact on the functional outcome in ADHD. However, little is known about the mechanisms underlying reactive aggression in ADHD. In this study, we aimed to identify the neural correlates of reactive aggression as a measure of emotionally dysregulated behavior in adults with persistent ADHD during implicit emotion regulation processes. We analyzed associations of magnetic resonance imaging-based whole-brain activity during a dynamic facial expression task with levels of reactive aggression in 78 adults with and 78 adults without ADHD, and also investigated relationships of reactive aggression with symptoms and impairments. While participants with ADHD had higher reactive aggression scores than controls, the neural activation patterns of both groups to processing of emotional faces were similar. However, investigating the brain activities associated with reactive aggression in individuals with and without ADHD showed an interaction of diagnosis and reactive aggression scores. We found high levels of activity in the right insula, the hippocampus, and middle and superior frontal areas to be particularly associated with high reactive aggression scores within the ADHD group. Furthermore, the limbic activity was associated with more hyperactivity/impulsivity symptoms. These results suggest a partly differential mechanism associated with reactive aggression in ADHD as compared to controls. Emotional hyper-reactivity in the salience network as well as more effortful top-down regulation from the self-regulation network might contribute to emotionally dysregulated behavior as measured by reactive aggression.

Abstract
OBJECTIVE This study investigated the direct medical and indirect (i.e. absenteeism) costs among working adults diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) in the United States. METHODS This study utilized 2017-2018 Medical Expenditure Panel Survey data. Attribution and regression-based incremental cost approaches were utilized to estimate direct medical costs, i.e. prescription drug costs and total costs. The regression-based approach was utilized to estimate absenteeism cost. RESULTS The study sample consisted of 32,222 observations (weighted: 187,207,896). Of these, 459 (weighted: 3,175,033) had ADHD. The mean annual per person ADHD-attributable prescription drug cost was 2018 US $1,248 (standard error (SE): 97) and the ADHD-attributable total cost was $2,031 (SE: 371). This contributed to a mean overall annual spending of $3.96 (SE: 0.42) billion on ADHD-attributable prescription drugs and $6.45 (SE: 1.26) billion on ADHD-attributable total direct medical costs among adult ADHD patients. Based on the regression-based approach, the mean annual incremental cost for ADHD was $1,641 (SE: 164) and $4,328 (SE: 862) per person for prescription medication costs and total costs, respectively. The mean indirect cost of ADHD was estimated at $512 (SE: 91) per year, per person among working adults with ADHD in the United States. CONCLUSIONS There is a significant direct and indirect economic burden on working adults with ADHD. EXPERT OPINION There is a significant economic burden of ADHD in terms of direct medical (including out-of-pocket) cost as well as indirect absenteeism cost. The per person annual costs estimated using a regression approach were approximately twice as much as the costs using the sum disease-specific approach, suggesting a potential role for 'spillover' costs among working adults with ADHD. Prescription drug costs were top-ranked contributors to the direct medical costs. As a group, working adults with ADHD are relatively understudied and more research is needed to better understand the burden of ADHD in this group.

Abstract
OBJECTIVE Validate the usability and treatment-sensitivity of a remote SMS-based ADHD monitoring method. METHOD 206 adults taking stimulants for ADHD participated. Participants selected ADHD symptoms and functional impairments that they anticipated to be stimulant-sensitive, which were rated via mobile messages up to 20 times over 10 days. RESULTS A majority of participants found it only somewhat or not at all difficult to identify an ADHD symptom sensitive to presence of stimulant medication, and 79% responded to at least one survey message. As expected, a majority of participants endorsed it was "easy" to participate, and less burdensome than a paper diary. Surveys significantly discriminated between on and off medication states, both between days, and within the same day. CONCLUSION Our findings suggest SMS-based monitoring of patient-selected ADHD-related challenges is both feasible and sensitive to stimulant treatment. This remote assay method may be a meaningful adjunct to in-visit treatment monitoring.

Abstract
OBJECTIVE Emerging adulthood (18-25 years) is a transitional and understudied developmental period. Yet, little is known about how specific symptoms of ADHD, as well as those from the related SCT domain, may differentially relate to one another during this period, if there are differences based on biological sex, or how closely results will align with adulthood. METHODS We used network analysis techniques to explore the structure of ADHD and SCT symptoms within emerging adulthood, with additional comparisons between sexes as well as between emerging adulthood and adulthood. Using an online platform, 8,506 adults reported on their symptoms of ADHD and SCT. RESULTS Symptoms grouped together within their respective domains during emerging adulthood with no significant differences in overall network structure between sexes. Similarly, network structure appeared to be robust across emerging adulthood and adulthood. CONCLUSION Such consistency supports a conceptualization of ADHD in emerging adulthood as similar to adulthood.

Abstract
Objectives: The present study compares the utility of eight different tests of vigilance and sustained attention in the neuropsychological examination of adults with Attention-deficit/hyperactivity disorder (ADHD). Methods: Thirty-one adults diagnosed with ADHD performed eight tests for vigilance and sustained attention, spread over three assessment days. Results: Adults with ADHD showed cognitive impairments in most tests and test variables, even though their sensitivity differed greatly. No specific type of test variable stands out to be the most sensitive, and no evidence for a differential deterioration of performance over time was observed. Conclusion: This study underscores the role of vigilance and sustained attention tests in the assessment of adult ADHD. It is further concluded that summary scores over the entire test duration are sufficient, but that all variables of a test should be considered. Finally, we hypothesize that reassessment on a different day may benefit a more accurate clinical assessment of adults with ADHD, in order to adequately take intraindividual fluctuations and limitations regarding test reliability into account.

Abstract
OBJECTIVE To evaluate the efficacy, safety, and duration of action of the once-daily extended-release methylphenidate formulation PRC-063 for the treatment of ADHD in an adult laboratory classroom (ALC). METHOD After dose optimization with PRC-063 over 7 weeks, adults with ADHD were randomized to 1 week of double-blind treatment with PRC-063 or placebo that ended with an ALC evaluation. The primary outcome measure was Permanent Product Measure of Performance-Total (PERMP-T) score. RESULTS Of 288 subjects enrolled, 221 completed the ALC visit. PERMP-T score was significantly higher for PRC-063 versus placebo at every assessment from 1 to 16 hours post-dose at the ALC visit and when averaged over 16 hours post-dose (least-squares mean difference 16.3, 95% confidence interval 7.6-24.9). The most frequent adverse events during dose optimization were headache, decreased appetite, and insomnia. CONCLUSION PRC-063 provided rapid and sustained symptom relief in adults with ADHD and was well tolerated. NCT03618030.

Abstract
OBJECTIVES Emotional dysregulation (ED) in adult ADHD is frequent but definition and tools for its evaluation are not consensual. Our aim was to determine the core ADHD symptomatic domains via the Self-Reported Wender-Reimherr Adult Attention Deficit Disorder Scale (SR-WRAADDS) following its validation in a large clinical sample of adults with ADHD and controls. METHOD Three hundred sixty-nine adult patients with ADHD and 251 healthy participants completed the SR-WRAADDS and questionnaires about ADHD, depression, and ED. We analyzed the psychometric properties of the SR-WRAADDS and a factor analysis yielded symptomatic domains. RESULTS The SR-WRAADDS has good reliability. The 30 symptoms were best organized in a four-factor solution: attention/disorganization, hyperactivity/restlessness, impulsivity/emotional outbursts, and emotional lability. CONCLUSIONS The symptomatic structure of the SR-WRAADDS includes two distinct dimensions related to ED: "impulsivity/emotional outbursts" and "emotional lability." The SR-WRAADDS is a reliable and clinically useful tool that assesses all ADHD symptom domains, including facets of ED.

Abstract
OBJECTIVE Time-processing disorders in adults is a priority area for intervention. Time management program, which has been demonstrated to be effective in children with ADHD, has not been examined in adults. We anticipate the need for the development of specialized programs for adults. This is because it has been reported that time processing disorders have different patterns in childhood and adulthood. This study aimed to evaluate the therapeutic effect of a gCBT program focusing on time management for adults with ADHD. METHOD Adults with ADHD were randomly assigned to gCBT (n = 24) or a treatment as usual group (n = 24). Outcome measures were masked clinically rated, self-reported, and family-reported ADHD symptoms. RESULTS The gCBT group significantly reduced ADHD symptoms on all measures. CONCLUSION Interventions focused on time management have been shown to be effective not only in children with ADHD but also in adult patients.

Abstract
OBJECTIVE To test our hypothesis that individuals with ADHD would exhibit reduced resiliency to subconcussive head impacts induced by ten soccer headings. METHOD We conducted a case-control intervention study in 51 adults (20.6 ± 1.7 years old). Cognitive assessment, using ImPACT, and plasma levels of neurofilament-light (NF-L), Tau, glial-fibrillary-acidic protein (GFAP), and ubiquitin-C-terminal hydrolase-L1 (UCH-L1) were measured. RESULTS Ten controlled soccer headings demonstrated ADHD-specific transient declines in verbal memory function. Ten headings also blunted learning effects in visual memory function in the ADHD group while the non-ADHD counterparts improved both verbal and visual memory functions even after ten headings. Blood biomarker levels of the ADHD group were sensitive to the stress induced by ten headings, where plasma GFAP and UCH-L1 levels acutely increased after 10 headings. Variance in ADHD-specific verbal memory decline was correlated with increased levels of plasma GFAP in the ADHD group. CONCLUSIONS These data suggest that ADHD may reduce brain tolerance to repetitive subconcussive head impacts.
