RESUMO

INTRODUCTION: Cognitive behavioral therapy and dialectical behavior therapy (DBT) can be effective in treating adults with ADHD, and patients generally consider these interventions useful. While adherence, as measured by attendance at sessions, is mostly sufficient, adherence to therapy skills has not been assessed. Furthermore, the relationship between patient evaluation of therapy effectiveness, treatment adherence, and clinical outcomes is understudied. OBJECTIVE: This study aimed to examine treatment acceptability and adherence in relation to treatment outcomes in a large randomized controlled trial comparing a DBT-based intervention with a nonspecific active comparison, combined with methylphenidate or placebo. METHOD: A total of 433 adult patients with ADHD were randomized. Participants reported how effective they found the therapy, and adherence was measured by attendance at therapy sessions and by self-reports. Descriptive, between-groups, and linear mixed model analyses were conducted. RESULTS: Participants rated psychotherapy as moderately effective, attended 78.40-94.37% of sessions, and used skills regularly. The best-accepted skills were sports and mindfulness. Groups receiving placebo and/or nonspecific clinical management rated their health condition and the medication effectiveness significantly worse than the psychotherapy and methylphenidate groups. Improvements in clinical outcomes were significantly associated with treatment acceptability. Subjective (self-reported) adherence to psychotherapy was significantly associated with improvements in ADHD symptoms, clinical global efficacy and response to treatment. DISCUSSION: These results further support the acceptability of DBT for adult ADHD and suggest the need to address adherence to treatment to maximize clinical improvements. Results may be limited by the retrospective assessment of treatment acceptability and adherence using an ad hoc instrument.

RESUMO

In the last two decades, numerous magnetic resonance imaging (MRI) studies have examined differences in cortical structure between individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) and healthy controls. These studies primarily emphasized alterations in gray matter volume (GMV) and cortical thickness (CT). Still, the scientific literature is notably scarce in regard to investigating associations of cortical structure with ADHD psychopathology, specifically inattention within adults with ADHD. The present study aimed to elucidate neurobiological underpinnings of inattention beyond GMV and CT by including cortical gyrification, sulcal depth, and fractal dimension. Building upon the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), cortical structure parameters were investigated using 141 T1-weighted anatomical scans of adult patients with ADHD. All brain structural analyses were performed using the threshold-free cluster enhancement (TFCE) approach and the Computational Anatomy Toolbox (CAT12) integrated into the Statistical Parametric Mapping Software (Matlab Version R2021a). Results revealed significant correlations of inattention in multiple brain regions. Cortical gyrification was negatively correlated, whereas cortical thickness and fractal dimension were positively associated with inattention. The clusters showed widespread distribution across the cerebral cortex, with both hemispheres affected. The cortical regions most prominently affected included the precuneus, para-, pre-, and postcentral gyri, superior parietal lobe, and posterior cingulate cortex. This study highlights the importance of cortical alterations in attentional processes in adults with ADHD. Further research in this area is warranted to elucidate intricacies of inattention in adults with ADHD to potentially enhance diagnostic accuracy and inform personalized treatment strategies.

RESUMO

INTRODUCTION: The Comparison of Methylphenidate and Psychotherapy in adult ADHD Study (COMPAS) was a prospective, randomized multicenter clinical trial, comparing methylphenidate (MPH) with placebo (PLAC) in combination with cognitive behavioral group psychotherapy (GPT) or individual clinical management (CM) over the period of 1 year. Here, we report results on treatment safety. METHODS: MPH and PLAC were flexibly dosed. Among 433 randomized patients, adverse events (AEs) were documented and analyzed on an "as received" basis during week 0-52. Electrocardiogram data were recorded at baseline and week 24. RESULTS: Comparing 205 patients who received ≥1 dose of MPH with 209 patients who received PLAC, AEs occurring significantly more frequently in the MPH group were decreased appetite (22 vs. 3.8%), dry mouth (15 vs. 4.8%), palpitations (13 vs. 3.3%), gastrointestinal infection (11 vs. 4.8%), agitation (11 vs. 3.3%), restlessness (10 vs. 2.9%), hyperhidrosis, tachycardia, weight decrease (all 6.3 vs. 1.9%), depressive symptom, influenza (both 4.9 vs. 1.0%), and acute tonsillitis (4.4 vs. 0.5%). Syncope occurred significantly more often in the PLAC group (2.4 vs. 0%). Clinically relevant ECG changes occurred very rarely in both groups. Serious AEs were rare and without a significant group difference. The comparison of 206 patients treated with GPT versus 209 patients who received CM revealed no major differences. Serious AE classified as psychiatric occurred in 5 cases in the CM group and in 1 case in the GPT group. CONCLUSION: In this so far longest-running clinical trial, methylphenidate treatment was safe and well-tolerated.

RESUMO

ADHD often affects multiple generations in a family. Previous studies suggested that children with ADHD benefit less from therapy if parents are also affected, since ADHD symptoms interfere with treatment implementation. This two-group randomised controlled trial examined whether targeting maternal ADHD boosts the efficacy of parent-child training (PCT) for the child's ADHD. Here, we report follow-up results 2 years from baseline. Mothers of 144 mother-child dyads (ADHD according to DSM-IV) were examined for eligibility (T1) and randomised to 12 weeks of intensive multimodal treatment comprising pharmacotherapy and DBT-based cognitive behavioural group psychotherapy (TG, n = 77) or clinical management comprising non-specific counselling (CG, n = 67) for Step 1 (concluded by T2). Subsequently, all dyads participated in 12 weekly PCT sessions for Step 2 (concluded by T3). In Step 3, participants received maintenance treatments for 6 months (concluded by T4). At 24 months after baseline (T5), we performed follow-up assessments. The primary endpoint was child ADHD/ODD score (observer blind rating). Outcomes at T5 were evaluated using ANCOVA. Assessments from 101 children and 95 mothers were available at T5. Adjusted means (m) of ADHD/ODD symptoms (range 0-26) in children did not differ between TG and CG (mean difference = 1.0; 95% CI 1.2-3.1). The maternal advantage of TG over CG on the CAARS-O:L ADHD index (range 0-36) disappeared at T5 (mean difference = 0.2; 95% CI - 2.3 to 2.6). Sensitivity analyses controlling for medication and significant predictors of follow-up participation showed unchanged outcomes. Within-group outcomes remained improved from baseline. At the 24-month follow-up, TG and CG converged. The superiority of intensive treatment regarding maternal symptoms disappeared. In general, cross-generational treatment seems to be effective in the long term. (BMBF grant 01GV0605; registration ISRCTN73911400).

RESUMO

BACKGROUND: Adult attention-deficit/hyperactivity disorder (ADHD) is a serious and frequent psychiatric disorder of multifactorial pathogenesis. Several lines of evidence support the idea that ADHD is, in its core, a disorder of dysfunctional brain connectivity within and between several neurofunctional networks. The primary aim of this study was to investigate associations between the functional connectivity within resting state brain networks and the individual severity of core ADHD symptoms (inattention, hyperactivity, and impulsivity). METHODS: Resting state functional magnetic resonance imaging (rs-fMRI) data of 38 methylphenidate-naïve adults with childhood-onset ADHD (20 women, mean age 40.5 years) were analyzed using independent component analysis (FSL's MELODIC) and FSL's dual regression technique. For motion correction, standard volume-realignment followed by independent component analysis-based automatic removal of motion artifacts (FSL's ICA-AROMA) were employed. To identify well-established brain networks, the independent components found in the ADHD group were correlated with brain networks previously found in healthy participants (Smith et al. PNAS 2009;106:13040-5). To investigate associations between functional connectivity and individual symptom severity, sex, and age, linear regressions were performed. RESULTS: Decomposition of resting state brain activity of adults with ADHD resulted in similar resting state networks as previously described for healthy adults. No significant differences in functional connectivity were seen between women and men. Advanced age was associated with decreased functional connectivity in parts of the bilateral cingulate and paracingulate cortex within the executive control network. More severe hyperactivity was associated with increased functional connectivity in the left putamen, right caudate nucleus, right central operculum and a portion of the right postcentral gyrus within the auditory/sensorimotor network. CONCLUSIONS: The present study supports and extends our knowledge on the involvement of the striatum in the pathophysiology of ADHD, in particular, in the pathogenesis of hyperactivity. Our results emphasize the usefulness of dimensional analyses in the study of ADHD, a highly heterogeneous disorder. TRIAL REGISTRATION: ISRCTN12722296 ( https://doi.org/10.1186/ISRCTN12722296 ).

RESUMO

OBJECTIVE: We examined predictors and moderators of treatment outcome in mothers and children diagnosed with ADHD in a large multicentre RCT. METHOD: In total, 144 mother-child dyads with ADHD were randomly assigned to either a maternal ADHD treatment (group psychotherapy and open methylphenidate medication, TG) or to a control treatment (individual counselling without psycho- or pharmacotherapy, CG). After maternal ADHD treatment, parent-child training (PCT) for all mother-child dyads was added. The final analysis set was based on 123 dyads with completed primary outcome assessments (TG: n = 67, CG: n = 56). The primary outcome was the change in each child's externalizing symptoms. Multiple linear regression analyses were performed. RESULTS: The severity of the child's externalizing problem behaviour in the family at baseline predicted more externalizing symptoms in the child after PCT, independent of maternal treatment. When mothers had a comorbid depression, TG children showed more externalizing symptoms after PCT than CG children of depressive mothers. No differences between the treatment arms were seen in the mothers without comorbid depression. CONCLUSIONS: Severely impaired mothers with ADHD and depressive disorder are likely to need additional disorder-specific treatment for their comorbid psychiatric disorders to effectively transfer the contents of the PCT to the home situation (CCTISRCTN73911400).

RESUMO

PURPOSE OF REVIEW: In light of the apparent symptomatic resemblance of separation anxiety disorder (SAD) symptoms on the one hand and abandonment fears, anxiousness, and separation insecurity central to borderline personality disorder (BPD) on the other hand, a comprehensive overview of separation anxiety and related traits in BPD is provided. RECENT FINDINGS: Epidemiological, environmental, psychological, and neurobiological data connecting BPD to separation events, feelings of loneliness, insecure attachment styles, dimensional separation anxiety as well as SAD per se suggest a partly shared etiological pathway model underlying BPD and SAD. Differential diagnostic aspects and implications for treatment are discussed, highlighting separation anxiety as a promising transdiagnostic target for specific psychotherapeutic and pharmacological treatment approaches in BPD. This innovative angle on cross-disorder symptomatology might carry potential for novel preventive and therapeutic avenues in clinical practice by guiding the development of interventions specifically targeting separation anxiety and attachment-related issues in BPD.

RESUMO

BACKGROUND: The efficacy of parent-child training (PCT) regarding child symptoms may be reduced if the mother has attention-deficit/hyperactivity disorder (ADHD). The AIMAC study (ADHD in Mothers and Children) aimed to compensate for the deteriorating effect of parental psychopathology by treating the mother (Step 1) before the beginning of PCT (Step 2). This secondary analysis was particularly concerned with the additional effect of the Step 2 PCT on child symptoms after the Step 1 treatment. METHODS: The analysis included 143 mothers and children (aged 6-12 years) both diagnosed with ADHD. The study design was a two-stage, two-arm parallel group trial (Step 1 treatment group [TG]: intensive treatment of the mother including psychotherapy and pharmacotherapy; Step 1 control group [CG]: supportive counseling only for mother; Step 2 TG and CG: PCT). Single- and multi-group analyses with piecewise linear latent growth curve models were applied to test for the effects of group and phase. Child symptoms (e.g., ADHD symptoms, disruptive behavior) were rated by three informants (blinded clinician, mother, teacher). RESULTS: Children in the TG showed a stronger improvement of their disruptive behavior as rated by mothers than those in the CG during Step 1 (Step 1: TG vs. CG). In the CG, according to reports of the blinded clinician and the mother, the reduction of children's disruptive behavior was stronger during Step 2 than during Step 1 (CG: Step 1 vs. Step 2). In the TG, improvement of child outcome did not differ across treatment steps (TG: Step 1 vs. Step 2). CONCLUSIONS: Intensive treatment of the mother including pharmacotherapy and psychotherapy may have small positive effects on the child's disruptive behavior. PCT may be a valid treatment option for children with ADHD regarding disruptive behavior, even if mothers are not intensively treated beforehand. TRIAL REGISTRATION: ISRCTN registry ISRCTN73911400 .

RESUMO

Multimodal treatment of children with ADHD often includes parent-child training (PCT). However, due to the high heritability, parents of children with ADHD are frequently also affected by the disorder, which is likely to constitute a significant barrier to successful treatment of the child. This secondary analysis of our randomized controlled multicentre AIMAC trial (ADHD in mothers and children) investigates whether children's outcomes following parent-child training in combination with maternal ADHD treatment depend on maternal symptom improvement. In a first step focusing on treatment of maternal ADHD, 144 mothers of mother-child dyads were randomized to multimodal ADHD treatment (group psychotherapy plus methylphenidate) or clinical management (mainly supportive counselling). After 12 weeks (T2), a 12-week PCT program (T2-T3) for all mother-child dyads was added to treat children's ADHD. Maternal symptomatology (CAARS-O:L; SCL-90-R) and children's externalizing symptoms (ADHD-ODD Scale, SDQ) were repeatedly assessed (T1 = baseline, T2, T3). Effects of changes in maternal symptomatology (T1-T2) on the change in children's symptom scores (T1-T3) were analysed using a general linear model, controlling for baseline scores, study centre, and maternal treatment group. 125 mother-child dyads were analysed. Mothers showed significant improvements in ADHD symptoms and overall psychopathology [CAARS-O:L ADHD index: mean - 3.54, SE 0.74 p < 0.0001; SCL-90-R Global Severity (GS): mean - 11.03, SE 3.90, p = 0.0056]. Although children's externalizing symptoms improved significantly (ADHD-ODD Scale: mean - 4.46, SE 0.58, p < 0.0001), maternal improvement had no effect on children's outcomes after Bonferroni-Holm correction for multiple testing. The findings do not support our hypothesis that children's outcomes following PCT for ADHD depend on maternal symptom improvements.Trial register CCT-ISRCTN73911400.

RESUMO

INTRODUCTION: Adult attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder. In subgroups of patients with a (para)epileptic pathomechanism, this might be due to intermittent rhythmic delta or theta activity (IRDA/IRTA). PARTICIPANTS AND METHODS: Using a fully data-driven analysis, we compared the IRDA/IRTA rates in the resting electroencephalography (EEG) results of 97 adult patients with ADHD and 30 control subjects. The IRDA/IRTA rates before hyperventilation (HV) and for HV difference (difference between IRDA/IRTA rate after and before HV) were compared between groups using a linear model. RESULTS: We detected significantly increased rates of IRDA/IRTA before HV (F=4.209, p=0.042) in patients with ADHD but no significant difference between the groups for HV-difference (F=2.46, p=0.119). DISCUSSION: The increased IRDA/IRTA rates before HV in the group with ADHD might lead to (para)epileptic short-term effects (e.g., impulsivity) via local area network inhibition, and to long-term effects (e.g., cognitive deficits) via connectivistic brain restructuring.

RESUMO

BACKGROUND: Based on animal research several authors have warned that the application of methylphenidate, the first-line drug for the treatment of attention-deficit/hyperactivity disorder (ADHD), might have neurotoxic effects potentially harming the brain. We investigated whether methylphenidate application, over a 1-year period, results in cerebral volume decrease. METHODS: We acquired structural MRIs in a double-blind study comparing methylphenidate to placebo. Global and regional brain volumes were analyzed at baseline, after 3 months and after 12 months using diffeomorphic anatomic registration through exponentiated lie algebra. RESULTS: We included 131 adult patients with ADHD into the baseline sample, 98 into the 3-month sample (54 in the methylphenidate cohort and 44 in the placebo cohort) and 76 into the 1-year sample (37 in the methylphenidate cohort and 29 in the placebo cohort). Methylphenidate intake compared with placebo did not lead to any detectable cerebral volume loss; there was a trend toward bilateral cerebellar grey matter increase. LIMITATIONS: Detecting possible neurotoxic effects of methylphenidate might require a longer observation period. CONCLUSION: There is no evidence of grey matter volume loss after 1 year of methylphenidate treatment in adult patients with ADHD.

RESUMO

Children suffering from attention deficit hyperactivity disorder (ADHD) may remit until adulthood. But, more than 60-80% have persisting ADHD symptoms. ADHD as an early manifesting neurodevelopmental disorder is considered a major risk factor for the development of comorbid psychiatric disorders in later life. Particularly, personality disorders are oftentimes observed in adult patients suffering from ADHD. If ADHD and personality disorders share common etiological mechanisms and/or if ADHD as a severely impairing condition influences psychological functioning and learning and leads to unfavorable learning histories is unclear. The development of inflexible and dysfunctional beliefs on the basis of real and perceived impairments or otherness due to the core symptoms of ADHD is intuitively plausible. Such beliefs are a known cause for the development of personality disorders. But, why some personality disorders are more frequently found in ADHD patients as for example antisocial and borderline personality disorder remains subject of debate. Because of the high prevalence of ADHD and the high impact of personality disorders on daily functioning, it is important to take them into account when treating patients with ADHD. Research on the developmental trajectories leading to personality disorders in adult ADHD patients might open the door for targeted interventions to prevent impairing comorbid clinical pictures.

RESUMO

BACKGROUND: This is the first randomized controlled multicenter trial to evaluate the effect of two treatments of maternal attention-deficit hyperactivity disorder (ADHD) on response to parent-child training targeting children's external psychopathology. METHODS: Mother-child dyads (n = 144; ADHD according to DSM-IV; children: 73.5% males, mean age 9.4 years) from five specialized university outpatient units in Germany were centrally randomized to multimodal maternal ADHD treatment [group psychotherapy plus open methylphenidate medication; treatment group (TG): n = 77] or to clinical management [supportive counseling without psychotherapy or psychopharmacotherapy; control group (CG): n = 67]. After 12 weeks, the maternal ADHD treatment was supplemented by individual parent-child training for all dyads. The primary outcome was a change in the children's externalizing symptom scores (investigator blinded to the treatment assignment) from baseline to the end of the parent-child training 6 months later. Maintenance therapy continued for another 6 months. An intention-to-treat analysis was performed within a linear regression model, controlling for baseline and center after multiple imputations of missing values. RESULTS: Exactly, 206 dyads were assessed for eligibility, 144 were randomized, and 143 were analyzed (TG: n = 77; CG: n = 66). After 6 months, no significant between-group differences were found in change scores for children's externalizing symptoms (adjusted mean TG-mean CG=1.1, 95% confidence interval -0.5-2.7; p = .1854), although maternal psychopathology improved more in the TG. Children's externalizing symptom scores improved from a mean of 14.8 at baseline to 11.4 (TG) and 10.3 (CG) after 6 months and to 10.8 (TG) and 10.1 (CG) after 1 year. No severe harms related to study treatments were found, but adverse events were more frequent in TG mothers than in CG mothers. CONCLUSIONS: The response in children's externalizing psychopathology did not differ between maternal treatment groups. However, multimodal treatment was associated with more improvement in maternal ADHD. Child and maternal treatment gains were stable (CCT-ISRCTN73911400).

RESUMO

BACKGROUND: Neuroimaging studies in attention-deficit/hyperactivity disorder (ADHD) demonstrated decreased global gray matter volume. In terms of surface parameters, most investigations focused on cortical thickness with a multi-center MEGA-analysis indicating cortical thinning in children, but not in adults with ADHD. In this single-scanner study, for the first time in adult ADHD, we additionally examined metrics beyond cortical thickness and surface area, namely sulcal depth and fractal dimension as measures of cortical alteration and complexity. Unlike most previous studies, ADHD subtypes were considered. METHODS: As part of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), surface parameters were analyzed in 131 adults with ADHD (66 combined, 60 inattentive and 5 hyperactive/impulsive subtype) and 95 healthy controls with the Computational Anatomy Toolbox (CAT12) using Statistical Parametric Mapping Software (SPM). RESULTS: Neither at the vertex- nor at the region of interest-level, the ADHD and control group differed significantly with regard to cortical thickness, gyrification index, sulcal depth or fractal dimension. Contrasting the combined and the inattentive subtype, patients of the combined subtype showed a significant thinning of the left anterior insular cortex. Thinner left pars opercularis cortical thickness was associated with symptoms of hyperactivity/restlessness. CONCLUSIONS: Resembling previous findings of a correlation of the left anterior insular gray matter volume with oppositional symptoms in adolescents with ADHD, we detected left anterior insular cortical thinning in the ADHD combined subtype. Left insular cortical thickness could represent a potential marker to distinguish the predominantly inattentive and the combined ADHD subtype in adulthood.

RESUMO

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

RESUMO

Impulsivity is a core feature of borderline personality disorder (BPD). Thereby, individuals with BPD are most often explicitly aware of the deleterious long-term consequences of their impulsive behaviors, but still engage in them. Therefore, the aim of the present study was to test decision-making in BPD. Female individuals with BPD (n=21) and female controls without BPD (CG; n=29) were compared on the Game of Dice Task (GDT) with regard to disadvantageous decision-making and feedback processing. In the GDT rules for reinforcement and punishment are explicitly clear and the outcome is defined by probabilities. By providing feedback about the outcome of previous decisions, the GDT is a valid measure to simulate decision-making in real life situations. Main results revealed that women with BPD make risky decisions significantly more often than the CG. Moreover, they show reduced capacities to advantageously utilize feedback. As deficits in decision-making were correlated with BPD symptom severity and impulsivity, risky decision-making may be a relevant maintenance factor for the disorder.

RESUMO

There is broad consensus that to improve the treatment of adult Attention-Deficit/Hyperactivity Disorder (ADHD), the various therapy options need to be tailored more precisely to the individual patient's needs and specific symptoms. This post-hoc analysis evaluates the multimodal effects of first-line medication (methylphenidate [MPH] vs placebo [PLB]) and psychotherapeutic (group psychotherapy [GPT] vs clinical management [CM]) treatments on the ADHD core symptoms inattention, hyperactivity and impulsivity. For the two-by-two factorial, observer-blinded, multicenter, randomized controlled Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS; ISRCTN54096201), 419 outpatients with ADHD were considered for analysis. ADHD symptoms were assessed by blind observer-rated and patient-rated Conners Adult ADHD Rating Scales before treatment (T1), 13 weeks (T2) and 26 weeks (T3) after T1, at treatment completion after 52 weeks (T4), and at follow-up (130 weeks, T5). MPH was superior to PLB in improving symptoms of inattention at almost all endpoints (observer-rated T2, T3, T4, T5; patient-rated T2, T3, T4), while a significant decrease in hyperactivity and impulsivity was at first found after 6 months of treatment. CM compared to GPT decreased inattention and impulsivity in the early treatment phase only (observer-rated T2, patient-rated T2, T3). In conclusion, while MPH seems to have a direct and sustained effect on inattention, premature medication discontinuation should particularly be avoided in patients with hyperactive-impulsive symptoms. Also, especially in high inattention and/or impulsivity presentations, initial individual patient management might be beneficial. Consequently, considering individual core symptom profiles may enhance the efficacy of treatments in adult ADHD.

RESUMO

BACKGROUND: Overlap in symptom domains particularly in the field of impulsivity and emotional dysregulation in attention deficit hyperactivity disorder (ADHD) and borderline personality disorder (BPD) have stimulated further research activities since our last review from 2014. MAIN BODY: Disentangling features of impulsivity in ADHD and BPD revealed that impulsivity is a feature of both disorders with patients suffering from both ADHD and BPD having highest impulsivity ratings. BPD individuals have more problems using context cues for inhibiting responses and their impulsivity is stress-dependent, whereas ADHD patients have more motor impulsivity and therefore difficulties interrupting ongoing responses. For emotion regulation difficulties the ranking order ranges from ADHD to BPD to the comorbid condition, again with the patients suffering from both, ADHD and BPD, having the most pronounced emotion regulation problems. Environmental influences namely adverse childhood events were shown to be linked to both ADHD and BPD. Traumatic experiences seem independently linked to impulsivity features. Thus, some authors point to the risk of misdiagnosis during childhood and the necessity to screen for traumatic experiences in both patient groups. Genetic research confirmed genetic overlap of BPD with bipolar disorder (BD) and schizophrenic disorders, as well as genetic overlap of BD and ADHD. A population-based study confirmed the high co-occurrence and familial co-aggregation of ADHD and BPD. Interesting questions in the field of gene-environment-interactions are currently dealt with by genetic and epigenetic research. Few studies have investigated treatment strategies for the comorbid condition, though the issue is highly important for the management of patients suffering from both disorders and presenting with the highest symptom scores. CONCLUSION: Research on the different impulsivity features might point to a necessity of disorder-specific treatment strategies in the field of impulse control. Future research is needed to base treatment decisions for the comorbid condition on an evidence basis.

RESUMO

Attention deficit hyperactivity disorder (ADHD) is a frequent neurodevelopmental disorder that often persists into adulthood. Methylphenidate (MPH) is the first-line treatment for ADHD; however, despite its wide usage, little is known about its neurometabolic effects. Until now, no randomized and blinded clinical trials have been conducted addressing the neurometabolic signals of MPH administration in adults with ADHD. In the current study, the authors investigated how MPH intake and group psychotherapy (GPT) influence brain neurometabolism over the course of three months. The authors hypothesized a decrease in the anterior cingulate cortex (ACC) glutamate concentration following MPH administration. This study was part of a double-blind multicenter trial (Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS)) investigating the effects of MPH and GPT in patients with adult ADHD. Using single-voxel magnetic resonance spectroscopy (MRS) of the pregenual ACC and the left cerebellar hemisphere (CHL), we investigated the concentration of glutamate plus glutamine (Glx), N-acetyl-aspartate, creatine, total choline containing compounds, and myo-inositol in patients before and after 12 weeks of treatment. Neither MPH nor GPT significantly influenced the Glx concentration or any of the other metabolite concentrations in the ACC and CHL after 12 weeks. Therefore, contrary to the hypothesis, no change in the prefrontal Glx signal was detected after MPH treatment. Given that MRS does not differentiate between glutamate in the synaptic cleft and in neuronal tissue, MPH-induced down-regulation of glutamatergic neurotransmission in the ACC might only affect the concentration of glutamate in the synaptic cleft, while the general availability of glutamate in the respective neuronal tissue might be unaffected by MPH intake. The observed lack of any MPH-induced normalization in metabolite concentrations is less surprising, considering that the baseline sample did not significantly differ from a healthy control group. Future studies of other regions, such as the basal ganglia, and the use of novel methods, such as whole brain MRS and multimodal imaging approaches, are necessary.
