Adult Attention Deficit Hyperactivity Disorder Symptoms Research Articles

Factors associated with attention deficit hyperactivity disorder symptoms among patients with substance use in Malaysia.

Attention deficit hyperactivity disorder (ADHD) often coexists with substance use disorders (SUDs). This study aimed to determine factors associated with ADHD symptoms among adults with SUDs in Malaysia. Patients aged ≥18 years with a ≥1-year history of substance use who were admitted to any of the three drug rehabilitation centres in urban Malaysia for >1 month were invited to participate. Participants were interviewed using the Malay version of the Alcohol, Smoking and Substance Involvement Screening Test to assess substance use and the Malay version of the Adult ADHD Self-Reporting Scale to assess ADHD symptoms. The prevalence of adult ADHD symptoms among participants with SUDs was 47.2%. Compared with participants without ADHD, a lower proportion of participants with ADHD had medical comorbidities (84.9% vs 93.3%, p = 0.018), whereas a higher proportion of participants with ADHD symptoms had a history of imprisonment (80.8% vs 65.6%, adjusted p = 0.018) and first imprisonment before the age of 18 years (24.6% vs 16.8%, adjusted p = 0.048). A high proportion of adults undergoing rehabilitation for SUDs have ADHD symptoms. Screening and interventions for ADHD should be integrated into SUD rehabilitation programmes.

Korean medicine treatments for adult Attention-Deficit/Hyperactivity Disorders: a single-clinic retrospective chart review

Objectives: Inattention and hyperactivity identified during childhood often persist into adulthood in patients with attention deficit hyperactivity disorder (ADHD). Despite increasing number of studies on the efficacy of herbal medicine for ADHD in children, there are limited reports on its use for adult ADHD. This retrospective chart review aimed to investigate which herbs and formulas are utilized for treating adult ADHD in a real clinical setting.Methods: From November 2015 to July 2019, eight cases of adult ADHD were selected through a retrospective chart review in a Korean medical clinic. Adult ADHD was diagnosed according to the DSM 5 diagnostic criteria. Individualized herbal medicine formulas, including <i>Acori graminei rhizoma</i>, <i>Polygalae radix</i>, <i>Angelicae gigantis radix</i>, and <i>Bupleuri radix</i>, were prescribed to treat symptoms of adult ADHD.Results: After administration of herbal medicine, all patients showed improved scores on at least one part of the attention task. Of the four patients with elevated omission errors, three showed improvement, and one showed no change. Among the four patients with delayed response times, two improved to within the normal range. All five patients tested for working memory showed improvement in the number of forward correct responses and forward spans. Mild adverse events, such as loose stools and indigestion, were reported.Conclusions: Korean medicine treatment, including herbal medicine, acupuncture, and neurofeedback, may potentially be effective for decreasing omission errors and increasing working memory span in adult patients with ADHD. Controlled trials are needed to explore the efficacy and safety of these combined interventions for improving the symptoms of adult ADHD.

Using Bifactor Twin Modeling to Assess the Genetic and Environmental Dimensionality of Adult ADHD Symptoms

Attention Deficit Hyperactivity Disorder (ADHD) is a common and heritable neurodevelopmental condition that has been the subject of a wealth of genetics research. Because ADHD has an early age of onset, most of this work has focused on children, meaning that less is known about the genetics of ADHD in adults. Additionally, while much research has assessed the heritability of ADHD as a general dimension, less has assessed the heritability of individual subtypes (inattention, hyperactivity) or symptoms of ADHD. It therefore remains unclear whether the genetic factors underlying ADHD symptoms conform to a unidimensional or multidimensional structure. The aim of this study was to assess the genetic and environmental dimensionality of adult ADHD symptoms. We analyzed data from 10,454 twins of the Twins Early Development Study, who provided self-reports of ADHD symptoms using the Conners scale at age 21 years. The data conformed well to a psychometric bifactor model, providing support for a general dimension of ADHD in addition to secondary dimensions for inattention and hyperactivity. However, a bifactor independent pathway twin model provided support for a general dimension only at the level of non-shared environmental effects and not additive genetic or shared environmental effects. This suggests that symptoms of ADHD cluster together under a general dimension of non-shared environmental effects, although the two subtypes of ADHD (inattention and hyperactivity) are meaningfully genetically distinct. We found the overall heritability of ADHD to be 40%, comparable with previous estimates for adult ADHD symptoms. Our results provide useful insights into the genetic and environmental architecture of specific ADHD symptoms.

Examining the utility of the BAARS-IV scales as embedded symptom validity indicators for adult attention-deficit/hyperactivity disorder evaluations

Objective: This study investigated whether extreme cut-scores on the Barkley Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale-Fourth Edition (BAARS-IV) self-report scales could serve as symptom overreporting indicators in adult ADHD evaluations. Method: The sample consisted of 162 adults who underwent a neuropsychological evaluation for ADHD. Patients were classified into valid (n = 115) and invalid (n = 47) groups based on multiple criterion symptom validity tests. Results: Overreporting cut-scores identified for each of the BAARS-IV scales demonstrated acceptable classification accuracy or better. The Current Total scale yielded the highest classification accuracy (area under the curve of .83). An optimal raw cut-score of ≥56 for this scale yielded 47% sensitivity when upholding ≥90% specificity. A cut-score of ≥31 for the Current Inattention scale (90% specificity; 47% sensitivity) and ≥29 for the Current Sluggish Cognitive Tempo scale (88% specificity; 46% sensitivity) were also relatively strong indicators of overreporting. The Current Total and Current Sluggish Cognitive Tempo scales captured nonredundant aspects of symptom validity, and using them together increased sensitivity to 57% while maintaining ≥90% specificity. Conclusions: Findings provide preliminary support for the criterion and construct validity of extreme cut-scores on the BAARS-IV Current Sluggish Cognitive Tempo, Current Inattention, and Current Total scales as indicators of ADHD symptom overreporting. However, employing the cut-scores from the Current Sluggish Cognitive Tempo (≥29) and Current Total (≥56) together may be the most promising way to detect overreporting. Scores above both of these cut-points should, at a minimum, prompt further investigation into the validity of a patient’s reported symptoms.

Measuring clinical outcomes in adult ADHD clinics: psychometrics of a new scale, the adult ADHD Clinical Outcome Scale.

Adult attention-deficit hyperactivity disorder (ADHD) clinics are in their infancy in Ireland and internationally. There is an urgent need for clinical evaluation of these services. Until now, clinical outcomes have relied mainly on functional scales and/or quality of life. However, adult ADHD is a longstanding disorder with many comorbidities. Although medication for ADHD symptoms can have immediate effects, co-occurring problems may take considerably longer to remediate. To present the psychometrics of a short outcome measure of key clinical areas including symptoms. The ADHD Clinical Outcome Scale (ACOS), developed by the authors, is a clinician-rated scale and was administered in consecutive adults attending an ADHD clinic. A modified version was completed by the participant. A second clinician independently administered the scale in a subsample. ACOS consists of 15 items rated on a Likert scale. Two self-report scales, the Adult ADHD Quality of Life Questionnaire (AAQoL) and Weiss Functional Impairment Rating Scale (WFIRS), were also administered. The mean age of 148 participants was 30.1 years (s.d. = 9.71), and 81 were female (54.7%). The correlation for interrater reliability was r = 0.868, and that between the participant and clinician versions was r = 0.663. The intraclass correlation coefficient for the internal consistency was 0.829, and the correlations for concurrent validity with total AAQoL and WFIRS scores were r = -0.573 and r = 0.477, respectively. Factor analysis revealed four factors: (a) attentional/organisational problems; (b) hyperactivity/impulsivity; (c) comorbidities; and (d) alcohol/drug use, self-harm and tension in relationships. The psychometrics of the ACOS are promising, and the inclusion of typically co-occurring clinical domains makes it suitable for use as a clinician-rated outcome measure in every contact with patients attending adult ADHD clinics.

How accurate is the QbTest for measuring symptoms of ADHD in children and adults?

This literature review aimed to assess the reliability and validity of the quantified behavioural test (QbTest) to measure the symptoms of attention deficit hyperactivity disorder (ADHD), determining the extent to which results of the selected studies were accurate and generalisable. A literature review was undertaken, with each paper appraised using the Critical Appraisal Skills Programme randomised controlled trial checklist. Thematic analysis was also implemented to identify key themes and relationships between data sets. Three papers concluded that the QbTest increases clinical efficiency without compromising diagnostic accuracy, while others identified limitations relating to its ability to identify symptoms of impulsivity correctly. Additional issues were identified relating to external validity, generalisability and the extent to which the QbTest could differentiate ADHD from other conditions. It is concluded that the QbTest is an unreliable means of assessing ADHD in both children and adults, particularly when used as a stand-alone assessment tool. Thematic analysis highlighted concerns around diagnostic accuracy and the QbTest's inability to differentiate symptoms of ADHD from other conditions – fundamental flaws affecting the overarching fidelity of QbTesting.

B - 61 Psilocybin as a First-Line Treatment of ADHD in Adult Populations

Abstract Objectives The first line for symptom management of attention deficit hyperactivity disorder (ADHD) is a class of medications that act on dopamine and noradrenaline receptors, which leads to symptom reduction at the cost of significant side effects. These side effects have led to community searching for alternative methods that manage ADHD symptoms in adults that lead to less side effects. Microdosing Psilocybin has emerged as a course of treatment that could provide benefits for those who may experience serious side effects to stimulant medication. Method This literature review was conducted using search terms such as, ADHD attention deficit hyperactivity disorder, psychedelic treatment, stimulant treatment of ADHD, naturalistic treatment of ADHD, 5-HT, neural plasticity. Journals that reported about the benefits and concerns of Psilocybin use for ADHD are Neurochemistry International, American College of Neuropharmacology, European Psychology, Movement and Nutrition in Health and Disease, Journal of Psychopharmacology, and Psychiatry Research. Results Research shows that not only does microdosing Psilocybin have less adverse effects than stimulant medications when being used to treat ADHD, but it also leads to an alternative method that focuses on serotonin receptors when other avenues are unsuccessful. Conclusions This poster illustrates the alternative use of Psilocybin for treatment in ADHD and highlights neurological underpinnings that may lead to explaining success. Limitations of stimulant medications are also reviewed.

Attachment Styles and Parenting Attitudes in Adults With "Pseudo-Attention-Deficit/Hyperactivity Disorder".

Background The number of individuals who experience the onset of attention-deficit/hyperactivity disorder (ADHD)-like symptoms after the age of 12 years has been growing, which does not meet the diagnostic criteria for adult ADHD. We designated this condition as "pseudo-ADHD" and investigated its psychological implications by comparing the parenting attitudes in childhood and attachment styles among individuals with "pseudo-ADHD," those with adult ADHD, and healthy controls. Methods We conducted an online cross-sectional survey of adults aged 18 years. Participants in the analysis included individuals with "pseudo-ADHD" (n = 46), adults with ADHD (n = 23), and healthy controls (n = 758). The Parental Bonding Instrument (PBI) was used to evaluate parenting attitudes, and the Experiences in Close Relationships Inventory for the Generalized Other (ECR-GO) was used to evaluate attachment styles. One-way analysis of variance was performed to compare the PBI and ECR-GO scores among the three groups. Results Regarding the PBI scores, a significant main effect of group was found for the paternal care scores (p = 0.002), and the "pseudo-ADHD" group did not differ significantly from the adult ADHD group or healthy control group (p = 0.378, p = 0.228, respectively). A significant main effect of the group was found for the maternal care scores (p < 0.001). The "pseudo-ADHD" group scored significantly lower than the adult ADHD group (p = 0.005), whereas there was no significant difference compared to the healthy control group (p = 1.000). A significant main effect of the group was also found for the paternal overprotection scores (p < 0.001). The "pseudo-ADHD" group scored significantly lower than the adult ADHD group (p = 0.002), whereas there was no significant difference compared to the healthy control group (p = 0.571). A significant main effect of group was found for the maternal overprotection scores (p < 0.001), and the "pseudo-ADHD" group did not differ significantly from either the adult ADHD group or the healthy control group (p = 0.060, p = 0.161, respectively). Regarding ECR-GO scores, a significant main effect of group was found for the fear of abandonment score (p < 0.001), and the "pseudo-ADHD" group scored significantly lower than the adult ADHD group (p < 0.001) and significantly higher than the healthy control group (p = 0.005). Conclusion This study suggested that the parenting attitudes of parents of individuals with "pseudo-ADHD" were not different from those of the healthy controls. For attachment styles, the fear of abandonment was higher in individuals with "pseudo-ADHD" than in healthy controls, but not as high as in patients with adult ADHD. This study highlights, for the first time, the importance of considering attachment styles in the diagnosis and treatment of individuals with ADHD symptoms in adulthood.

Prevalence, associated factors and consequence of problematic smartphone use among adolescents and young adults in Bangladesh: A cross-sectional study.

Problematic smartphone use (PSU) and attention deficit hyperactivity disorder (ADHD) in children, adolescents, and young adults are of major concern to parents. However, the prevalence and associated factors related to these issues in Bangladeshi adolescents and young adults remain unclear to the best of our knowledge. The aim of this study is to assess PSU and ADHD in the context of adolescent and young adult age groups in Bangladesh. The present study collected data from diverse geographical locations in Bangladesh via face-to-face surveys using stratified random sampling methods. We considered age, sex, and geographic location stratification criteria. A total of 578 respondents participated in the survey initially. From this, we discarded 36 responses after screening because the information provided was insufficient or incomplete response. In the end, 542 replies were incorporated into the final analysis. PSU and ADHD depend on several factors, including the individual's demographic background. The prevalence of PSU and ADHD symptoms in adolescents and young adults in Bangladesh is 61.44% and 37.45%, respectively based on our findings. The symptoms of PSU are correlated with age, education level, family type (nuclear/joint), sleeping pattern, physical exercise, and residence area. ADHD symptoms are correlated with age, education level, living with family, smoking habit, physical disability, sleeping pattern, physical exercise, residence area, and PSU. Also, we observed that ADHD and PSU symptoms are positively correlated with each other. A large proportion of young adults and adolescents reported PSU and ADHD symptoms. The present findings have practical implications in clinical psychology, psychotherapy, and related policy considerations. We propose to develop an inclusive interventional strategy and community-based programs to address PSU and ADHD-related issues.

Neurocognitive Characteristics of Patients Who Visited a Psychiatric Outpatient Clinic Requesting Treatment for Adult Attention-Deficit/Hyperactivity Disorder.

This study investigated the neurocognitive characteristics of patients who visited an outpatient clinic requesting diagnosis and treatment for adult attention-deficit/hyperactivity disorder (ADHD). The patients' electronic medical records were retrospectively reviewed. Neurocognitive test results were compared using Student's t-test according to their chief complaint, depressive symptoms, childhood history, and intelligence quotient (IQ). Neurocognitive characteristics affecting subjective symptoms of ADHD were analyzed by linear regression. The study included 106 patients. They did not have significant deficits in neurocognitive tests. Patients with depressive symptoms showed more impulsive responses (hit reaction time [p=0.037] and commission error [p=0.024]) and self-reported ADHD symptoms (p=0.001). Verbal (p=0.036) and visual memory (p=0.020) were significantly deficient in patients with a childhood ADHD diagnosis. Patients with a low IQ had significant deficits in various domains. Depressive symptoms and vigilance were significantly related to subjective symptoms of ADHD (adjusted R2=0.430, β=0.457, p=0.002). Our results imply that the neurocognitive function of patients with subjective ADHD symptoms was not abnormal but was affected by depressive symptoms.

Associations of Adult ADHD symptoms with binge eating spectrum conditions, psychiatric and somatic comorbidity, and healthcare utilization in a metropolitan Brazilian city.

To investigate the associations among symptoms of attention deficit hyperactivity disorder (ADHD) with binge eating spectrum conditions - BESC - [binge eating disorder (BED), bulimia nervosa (BN), and recurrent binge eating (RBE)], and psychiatric and somatic comorbidity and healthcare utilization in a representative sample of a Brazilian city. A household survey with 2,297 adults and residents in Rio de Janeiro was conducted. The Adult Self-Rating Scale Screener was used to assess ADHD symptoms. BESC was assessed using the Questionnaire of Eating and Weight Patterns 5 and confirmed by telephone interview. Standardized questionnaires were used to assess psychiatric comorbidity. Close-ended questions investigated somatic comorbidity and healthcare utilization. ADHD symptoms were highly associated with BESC [BED, OR=13.2, 95%CI= 4.3-40.6; BN, OR=27.5, 95%CI= 5.9-128.7; RBE, OR=5.8, 95%CI= 2.9-11.4). However, with further adjustment for psychiatric comorbidity (depression, anxiety, alcohol use and impulsivity), the ORs were no longer significant. Healthcare resource utilization was significantly higher in participants with ADHD and BESC but lost significance after controlling for the psychiatric comorbidity. ADHD was associated with an increased prevalence of BESC, and healthcare utilization. Nonetheless, there was an essential interplay among psychiatric comorbidity in the associations of ADHD and BESC.

Gene - maltreatment interplay in adult ADHD symptoms: main role of a gene-environment correlation effect in a Brazilian population longitudinal study.

Childhood maltreatment correlates with attention-deficit/hyperactivity disorder (ADHD) in previous research. The interaction between ADHD genetic predisposition and maltreatment's impact on ADHD symptom risk remains unclear. We aimed to elucidate this relationship by examining the interplay between a polygenic score for ADHD (ADHD-PGS) and childhood maltreatment in predicting ADHD symptoms during young adulthood. Using data from the 2004 Pelotas (Brazil) birth cohort comprising 4231 participants, we analyzed gene-environment interaction (GxE) and correlation (rGE). We further explored rGE mechanisms through mediation models. ADHD symptoms were assessed at age 18 via self-report (Adult Self Report Scale - ASRS) and mother-reports (Strength and Difficulties Questionnaire - SDQ). The ADHD-PGS was derived from published ADHD GWAS meta-analysis. Physical and psychological child maltreatment was gauged using the Parent-Child Conflict Tactics Scale (CTSPC) at ages 6 and 11, with a mean score utilized as a variable. The ADHD-PGS exhibited associations with ADHD symptoms on both ASRS (β = 0.53; 95% CI: 0.03; 1.03, p = 0.036), and SDQ (β = 0.20; 95% CI: 0.08; 0.32, p = 0.001) scales. The total mean maltreatment score was associated with ADHD symptoms using both scales [(βASRS = 0.51; 95% CI: 0.26;0.77) and (βSDQ = 0.24; 95% CI: 0.18;0.29)]. The ADHD-PGS was associated with total mean maltreatment scores (β = 0.09; 95% CI: 0.01; 0.17; p = 0.030). Approximately 47% of the total effect of ADHD-PGS on maltreatment was mediated by ADHD symptoms at age 6. No evidence supported gene-environment interaction in predicting ADHD symptoms. Our findings underscore the significant roles of genetics and childhood maltreatment as predictors for ADHD symptoms in adulthood, while also indicating a potential evocative mechanism through gene-environment correlation.

Associations between attention-deficit hyperactivity disorder genetic liability and ICD-10 medical conditions in adults: utilizing electronic health records in a Phenome-Wide Association Study.

Attention-deficit hyperactivity disorder (ADHD) is often comorbid with other medical conditions in adult patients. However, ADHD is extremely underdiagnosed in adults and little is known about the medical comorbidities in undiagnosed adult individuals with high ADHD liability. In this study we investigated associations between ADHD genetic liability and electronic health record (EHR)-based ICD-10 diagnoses across all diagnostic categories, in individuals without ADHD diagnosis history. We used data from the Estonian Biobank cohort (N = 111 261) and generated polygenic risk scores (PRS) for ADHD (PRSADHD) based on the ADHD genome-wide association study. We performed a phenome-wide association study (PheWAS) to test for associations between standardized PRSADHD and 1515 EHR-based ICD-10 diagnoses in the full and sex-stratified sample. We compared the observed significant ICD-10 associations to associations with (1) ADHD diagnosis and (2) questionnaire-based high ADHD risk analyses. After Bonferroni correction (p = 3.3 × 10-5) we identified 80 medical conditions associated with PRSADHD. The strongest evidence was seen with chronic obstructive pulmonary disease (OR 1.15, CI 1.11-1.18), obesity (OR 1.13, CI 1.11-1.15), and type 2 diabetes (OR 1.11, CI 1.09-1.14). Sex-stratified analysis generally showed similar associations in males and females. Out of all identified associations, 40% and 78% were also observed using ADHD diagnosis or questionnaire-based ADHD, respectively, as the predictor. Overall our findings indicate that ADHD genetic liability is associated with an increased risk of a substantial number of medical conditions in undiagnosed individuals. These results highlight the need for timely detection and improved management of ADHD symptoms in adults.

Prevalence of adult attention deficit hyperactivity disorder (ADHD) among medical students in the Eastern Province of Saudi Arabia.

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. 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. 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). 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.

Effectiveness of an online dialectical behavior therapy skills training in adults with attention-deficit/hyperactivity disorder: A randomized controlled trial

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.

Adult attention-deficit/hyperactivity symptoms and parental cognitions: a meta-analysis.

Attention-deficit/hyperactivity disorder (ADHD) symptoms in adults interfere with parental functioning. Dysfunctional parental cognitions may play a role in this impairment. Despite the importance of parental cognitions on parents and children's outcomes, up to now, no systematic review or meta-analysis of these findings is available. To fill this gap, this meta-analysis aimed to evaluate the relationship between adult ADHD symptoms and parental cognitions. We conducted searches in Web of Science, PubMed, and ProQuest from January 2000 to June 2023. Studies were included if they provided data on the relationship between parental ADHD symptoms and parental cognitions by means of a row correlational coefficient, or means and standard deviation were reported for each study group. A random-effects model was used. Publication bias was assessed by funnel plot and Rosenthal's fail-safe N. Moderator analyses were conducted by means of subgroup analysis and meta-regression analyses. Fifteen published papers were included (N = 2851), and 51 effect sizes were analysed. The weighted mean effect size was small but significant (Fisher's Z = 0.186, k = 15, 95% CI [0.120 - 0.252], z = 5.539, p < 0.001), indicating that ADHD symptoms in adults are associated with more negative and less positive parental cognitions. The Fail-Safe N analysis suggested a robust effect. Tweedie's trim and fill results suggested that five studies were missing; after five missing studies had been imputed, the mean overall effect size dropped to 0.116 (0.080 - 0.152). There was significant heterogeneity among effect sizes. The methodology of the study was found to be a significant moderator. Meta-regression analyses revealed that the lower age of the parent and the child were related to more negative parental cognitions. Though the analysis might be inflated by publication bias, our results suggest a significant association between ADHD symptom level and dysfunctional parental cognitions. Biased negative perceptions of the parental role, the child and co-parenting may play a central mediator role between parental ADHD and parent and child outcomes. Given the familiar nature of ADHD, targeting dysfunctional parental cognitions in parent training programs is warranted. osf.io/pnur7.

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

The role of emotional dysregulation (ED) in attention-deficit/hyperactivity disorder (ADHD) has become an important issue. This study, in which we analyzed data from a predictive pharmaco-EEG-trial, aimed to examine whether symptoms of ED in adult ADHD affect ADHD symptom severity, brain arousal regulation as measured by resting EEG, and the response to stimulant medication. ED is defined as having a sex- and age-corrected T-score of >70 on the emotional lability subscale of the German version of Conners' Adult ADHD Rating Scale. A total of 115 participants were included in the study, 56 of whom had ED. Participants with ED were more impaired in terms of the severity of core ADHD symptoms, especially inattentive symptoms, comorbid depressive symptoms, interpersonal relationships, and quality of life. In addition, participants with ED were more likely to report a total score above 13 on the Beck Depression Inventory-II, which was considered to be the cutoff for mild depression. No differences were found between the ED and non-ED groups in response to stimulant medication or in brain arousal regulation. In addition, there was no significant effect of ED with comorbid depressive symptoms on treatment response. There was a trend for subgroups that showed a change in brain arousal regulation associated with symptom improvement. Our findings may support the assumption that ED may be an important feature of ADHD. The use of EEG-based brain arousal regulation as a diagnostic and predictive tool in ADHD in the presence of ED and comorbid depressive symptoms should be further investigated.

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

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

Eficácia da Terapia Cognitivo-Comportamental para adultos com TDAH: Uma Revisão Sistemática

Abstract: Attention-deficit/hyperactivity disorder (ADHD) impacts individuals’ adaptive functioning from childhood through adulthood. The first-line treatment for adults with ADHD is pharmacological intervention, with cognitive-behavioral therapy (CBT) also being recommended. However, CBT efficacy remains under-researched in this population. We conducted a systematic review of randomized clinical trials to investigate the effectiveness of CBT in improving the core ADHD symptoms in adults. Data were extracted following PRISMA guidelines, including studies published from January 2012 to August 2022. We performed scientometric and descriptive analyses, finding that CBT improved aspects related to the disorder’s core symptoms and individuals’ daily functioning. Future research is recommended to delve deeper into the efficacy of CBT, aiding in understanding the cognitive and behavioral processes influencing the expression of core symptoms of the disorder.

Abnormal wiring of the structural connectome in adults with ADHD.

Current knowledge of white matter changes in large-scale brain networks in adult attention-deficit/hyperactivity disorder (ADHD) is scarce. We collected diffusion-weighted magnetic resonance imaging data in 40 adults with ADHD and 36 neurotypical controls and used constrained spherical deconvolution-based tractography to reconstruct whole-brain structural connectivity networks. We used network-based statistic (NBS) and graph theoretical analysis to investigate differences in these networks between the ADHD and control groups, as well as associations between structural connectivity and ADHD symptoms assessed with the Adult ADHD Self-Report Scale or performance in the Conners Continuous Performance Test 2 (CPT-2). NBS revealed decreased connectivity in the ADHD group compared to the neurotypical controls in widespread unilateral networks, which included subcortical and corticocortical structures and encompassed dorsal and ventral attention networks and visual and somatomotor systems. Furthermore, hypoconnectivity in a predominantly left-frontal network was associated with higher amount of commission errors in CPT-2. Graph theoretical analysis did not reveal topological differences between the groups or associations between topological properties and ADHD symptoms or task performance. Our results suggest that abnormal structural wiring of the brain in adult ADHD is manifested as widespread intrahemispheric hypoconnectivity in networks previously associated with ADHD in functional neuroimaging studies.
