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.

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.

Key Points Question What are the long-term results of multimodal treatment for adult attention-deficit/hyperactivity disorder (ADHD) when comparing cognitive behavioral group psychotherapy (GPT) with individual clinical management (CM) in combination with either methylphenidate or placebo? Findings In this follow-up assessment of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), a multicenter randomized clinical trial, 256 adults participated in follow-up 1.5 years after the intervention ended. The severity of ADHD symptoms improved in all 4 prior treatment groups, with no significant difference found between GPT and CM, but methylphenidate was associated with a larger improvement in symptoms compared with placebo. Meaning Results from the COMPAS trial demonstrate an improvement of ADHD symptoms over 1.5 years in adults with ADHD after 1 year of treatment with methylphenidate plus either GPT or CM., This follow-up assessment of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), a multicenter randomized clinical trial, evaluates the long-term efficacy of multimodal treatment for attention-deficit/hyperactivity disorder (ADHD)., Importance Knowledge about the long-term effects of multimodal treatment in adult attention-deficit/hyperactivity disorder (ADHD) is much needed. Objective To evaluate the long-term efficacy of multimodal treatment for adult ADHD. Design, Setting, and Participants This observer-masked, 1.5-year follow-up of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), a prospective, multicenter randomized clinical trial, compared cognitive behavioral group psychotherapy (GPT) with individual clinical management (CM) and methylphenidate (MPH) with placebo (2 × 2 factorial design). Recruitment started January 2007 and ended August 2010, and treatments were finalized in August 2011 with follow-up through March 2013. Overall, 433 adults with ADHD participated in the trial, and 256 (59.1%) participated in the follow-up assessment. Analysis began in November 2013 and was completed in February 2018. Interventions After 1-year treatment with GPT or CM and MPH or placebo, no further treatment restrictions were imposed. Main Outcomes and Measures The primary outcome was change in the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score from baseline to follow-up. Secondary outcomes included further ADHD rating scale scores, observer-masked ratings of the Clinical Global Impression scale, and self-ratings of depression on the Beck Depression Inventory. Results At follow-up, 256 of 433 randomized patients (baseline measured in 419 individuals) participated. Of the 256 patients participating in follow-up, the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score was assessed for 251; the mean (SD) baseline age was 36.3 (10.1) years; 125 patients (49.8%) were men; and the sample was well-balanced with respect to prior randomization (GPT and MPH: 64 of 107; GPT and placebo: 67 of 109; CM and MPH: 70 of 110; and CM and placebo: 55 of 107). At baseline, the all-group mean ADHD Index of Conners Adult ADHD Rating Scale score was 20.6, which improved to adjusted means of 14.2 for the GPT arm and 14.7 for the CM arm at follow-up with no significant difference between groups (difference, −0.5; 95% CI, −1.9 to 0.9; P = .48). The adjusted mean decreased to 13.8 for the MPH arm and 15.2 for the placebo arm (difference, −1.4; 95% CI, −2.8 to −0.1; P = .04). As in the core study, MPH was associated with a larger reduction in symptoms than placebo at follow-up. These results remained unchanged when accounting for MPH intake at follow-up. Compared with participants in the CM arm, patients who participated in group psychotherapy were associated with less severe symptoms as measured by the self-reported ADHD Symptoms Total Score according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (DSM-IV) of Conners Adult ADHD Rating Scale (AMD, −2.1; 95% CI, −4.2 to −0.1; P = .04) and in the subscale of reducing pure hyperactive symptoms, measured via the Diagnostic Checklist for the diagnosis of ADHD in adults (AMD, −1.3; 95% CI, −2.8 to 0.1; P = .08). Regarding the Clinical Global Impression scale assessment of effectiveness, the difference between GPT and CM remained significant at follow-up (odds ratio, 1.63; 95% CI, 1.03-2.59; P = .04). No differences were found for any comparison concerning depression as measured with the Beck Depression Inventory. Conclusions and Relevance Results from COMPAS demonstrate a maintained improvement in ADHD symptoms for adults 1.5 years after the end of a 52-week controlled multimodal treatment period. The results indicate that MPH treatment combined with GPT or CM provides a benefit lasting 1.5 years. Confirming the results of the core study, GPT was not associated with better results regarding the primary outcome compared with CM. Trial Registration isrctn.org Identifier: ISRCTN54096201

Objective: In the multicenter study Comparison of Methylphenidate and Psychotherapy in Adult ADHD (COMPAS), the efficacy of treatments has been primarily evaluated by observer-rated symptom change. Here, we additionally analyzed the patients’ subjective evaluation of therapy effects. Method: COMPAS compared ADHD-specific group therapy with unspecific clinical management with/without concomitant pharmacotherapy in a four-armed design. Evaluation through the patients’ retrospective perspective was performed after 1 year (post-treatment) and after another 1.5 years (follow-up). Results: In respect to patients’ subjective ratings, ADHD-specific group psychotherapy outperformed unspecific management post-treatment (z = 4.88, p < .0001) and at follow-up (z = 2.90, p = .004). Rank correlations with rater-based symptom change were small to moderate (post-treatment: rs = 0.28, follow-up: rs = 0.16). Conclusion: Therapy evaluation based on the patients’ perspective supports the concept of ADHD-specific group psycho...

Attention deficit hyperactivity disorder (ADHD) is a common neuropsychiatric condition that has been strongly associated with changes in sleep and circadian rhythms. Circadian rhythms are near 24-h cycles that are primarily generated by an endogenous circadian timekeeping system, encoded at the molecular level by a panel of clock genes. Stimulant and non-stimulant medication used in the management of ADHD has been shown to potentially impact on circadian processes and their behavioral outputs. In the current study, we have analyzed circadian rhythms in daily activity and sleep, and the circadian gene expression in a cohort of healthy controls (N = 22), ADHD participants not using ADHD-medication (N = 17), and participants with ADHD and current use of ADHD medication (N = 17). Rhythms of sleep/wake behavior were assessed via wrist-worn actigraphy, whilst rhythms of circadian gene expression were assessed ex-vivo in primary human-derived dermal fibroblast cultures. Behavioral data indicate that patients with ADHD using ADHD-medication have lower relative amplitudes of diurnal activity rhythms, lower sleep efficiency, more nocturnal activity but not more nocturnal wakenings than both controls and ADHD participants without medication. At the molecular level, there were alterations in the expression of PER2 and CRY1 between ADHD individuals with no medication compared to medicated ADHD patients or controls, whilst CLOCK expression was altered in patients with ADHD and current medication. Analysis of fibroblasts transfected with a BMAL1:luc reporter showed changes in the timing of the peak expression across the three groups. Taken together, these data support the contention that both ADHD and medication status impact on circadian processes.

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 .

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).

Background Neurofunctional deficits in chronic depression (CD) have been understudied. Specifically there is no known published study of the effects of a specialized psychotherapy for CD (CBASP) on neurofunctional deficits. Methods Ten patients with a DSM-IV diagnosis of CD received a 12 week specialised psychotherapy (CBASP). Controls were healthy matched volunteers. All subjects participated in a prospective study with functional magnetic resonance imaging (fMRI) at baseline and after 12 weeks. During the fMRI scans, subjects performed an implicit and explicit emotional processing task while watching dynamic displays of neutral, positive (happy) and negative (fearful and sad) facial expressions. Effects of treatment were analyzed in a repeated measures design. The analysis was restricted to two anatomically defined regions of interest (ROI): the amygdala and the cingulum. Results 60% of patients responded to treatment. Patients with CD reported increased arousal to negative emotional expressions. They also showed an increase in left amygdala reactivity during implicit processing of emotional expressions following psychotherapy. We found no significant effect for the cingulum. Limitations The main limitation of our study is the small sample size. Due to the lack of a control group it is also unclear whether the demonstrated effect is specific to the psychotherapy used in this study. Conclusions For the first time our study demonstrates an effect of CBASP on neural processing of facial emotions in CD. It therefore adds to the growing evidence supporting this treatment.

Background As data on the phenotype, characteristics and management of patients with Fragile X Syndrome (FXS) are limited, we aimed to collect such data in Germany in experienced centres involved in the treatment of such patients. Methods EXPLAIN-FXS is a prospective observational (non- interventional) study (registry) performed between April 2013 and January 2016 at 18 sites in Germany. Requirements for patient participation included confirmed diagnosis of FXS by genetic testing (>200 CGG repeats) and written informed consent. Patients were followed for up to 2 years. Results Seventy- five patients (84.0 % males, mean age 16.7 ± 14.5 years, ranging from 2 - 82 years) were analysed. The mean 6-item score, determined according to Giangreco (J Pediatr 129:611-614, 1996), was 6.9 ± 2.5 points. At least one neurological finding each was noted in 53 patients (69.7 %). Specifically, ataxia was noted in 5 patients (6.6 %), lack of fine motor skills in 40 patients, (52.6 %), muscle tonus disorder in 4 patients (5.3 %), and other neurological disorders in 39 patients (51.3 %). Spasticity was not noted in any patient. Seizures were reported in 6 patients (8.1 %), anxiety disorders in 22 patients (30.1 %), depression in 7 patients (9.6 %), ADHD/ADD in 36 patients (49.3 %), impairment of social behavior in 39 patients (53.4 %), and other comorbidities in 23 patients (31.5 %). The mean Aberrant Behaviour Checklist Community Edition (ABC-C) score on behavioral symptoms, obtained in 71 patients at first documentation, was 48.4 ± 27.8 (median 45.0, range 5-115). The mean visual analogue scale (VAS) score, obtained in 59 patients at first documentation, was 84.9 ± 14.6 points (median 90; range 50 – 100). Conclusions This report describes the largest cohort of patients with FXS in Europe. The reported observations indicate a substantial burden of disease for patients and their caregivers. Based on these observations, an early expert psychiatric diagnosis is recommended for suspected FXS patients. Further recommendations include multimodal and multi-professional management that is tailored to the individual patient’s needs. Trial registration The ClinTrials.gov identifier is NCT01711606.

Objective: This pilot study was a comparison of dimensional models assessing personality traits and personality pathology in a clinical sample of adults diagnosed with ADHD and adults diagnosed with borderline personality disorder (BPD), and a nonclinical control sample of healthy adults. Method: Personality traits were assessed using the NEO–Personality Inventory–Revised (NEO-PI-R) and dimensional personality pathology with the Dimensional Assessment of Personality Pathology–Basic Questionnaire (DAPP-BQ). Results: Adults with ADHD and BPD produced higher Emotional Dysregulation/Neuroticism and Dissocial Behavior scores than controls. For the Extraversion/Inhibitedness scale, adults with BPD produced significantly lower scores than adults with ADHD and controls. On the Conscientiousness/Compulsivity domains, Conscientiousness scores were lower for both disorders, whereas low Compulsivity values were specific to adult ADHD. Conclusion: Our results suggest that patients with adult ADHD and BPD have distinguishable profiles of personality traits and personality pathology.

Parental ADHD may be a significant barrier to a successful treatment for the child's ADHD. The objective of our randomized controlled trial was to evaluate whether the treatment for maternal ADHD improves the efficacy of a behavioural parent training for children's ADHD. Patient enrolment and a description of the full analysis set (FAS) of mother-child pairs with non-missing baseline data are presented. One hundred and forty-four mother-child pairs were randomized to two treatments for maternal ADHD: cognitive behavioural group psychotherapy plus open methylphenidate treatment or control treatment (supportive counselling). After 3 months of treatment for maternal ADHD, mother-child pairs participated in a behavioural parent-child training. Assessment for eligibility included standardized instruments. After pre-screening out of 444 mother-child pairs, 206 were evaluated for trial participation and 144 were randomized. The FAS was built up by 143 dyads (children: mean age 9.4 years, 73 % males; mothers: mean age: 38.3 years). Fifty-two per cent of the children and 66 % of the mothers had combined ADHD subtype. Current axis-I co-morbidity rates were 48 % in children and 31 % in mothers. Maternal axis-II co-morbidity was 20.1 %. Fifty-seven per cent of the mothers lived together with the father of the index-child, and 29 % were single mothers. Sixty-two per cent had part-time or full-time employment. There was a selection bias excluding mothers with lack of time and effort for participation and mothers affected by coexisting mental and physical illness. Nevertheless, for our trial we were able to collect a sample comparable to routine psychiatric outpatient settings (registration: CCT-ISRCTN73911400, funding: BMBF-01GV0605).

ADHD is a serious risk factor for co-occurring psychiatric disorders and negative psychosocial consequences in adulthood. Previous trials on psychotherapeutic concepts for adult ADHD are based on behavioural (cognitive behavioural and dialectical behavioural) psychotherapeutic approaches and showed significant effects. The aim of our study group (COMPAS) is to carry out a first randomized and controlled multicentre study to evaluate the effects of a disorder tailored psychotherapy in adult ADHD compared to clinical management in combination with psychopharmacological treatment or placebo. A total of 448 adults with ADHD according to DSM-IV will be treated at seven university sites in Germany. In a four-arm design, patients are randomized to a manualized dialectical behavioural therapy (DBT) based group programme plus methylphenidate or placebo or clinical management plus methylphenidate or placebo with weekly sessions in the first 12 weeks and monthly sessions thereafter. Therapists are graduated psychologists or physicians. Treatment integrity is established by independent supervision. Primary endpoint (ADHD symptoms measured by the Conners Adult Rating Scale) is rated by interviewers blind to the treatment allocation. Intention-to-treat analysis will be performed within a linear regression model (Current Controlled Trials ISRCTN54096201). The trial is funded by the German Federal Ministry of Research and Education (01GV0606) and is part of the German network for the treatment of ADHD in children and adults (ADHD-NET).

While an excess of glucocorticoids is associated with hippocampal pathology in mood disorders, lithium exerts robust neuroprotective and neurotrophic effects. Here, 21 stably remitted bipolar I patients who had been on chronic lithium maintenance therapy, on average, for more than a decade, and 19 carefully matched healthy controls were studied using 3 T (1)H-magnetic resonance spectroscopy of left and right hippocampus. Salivary cortisol samples were obtained to assess activity of the hypothalamus-pituitary-adrenal system. Absolute concentrations of N-acetylaspartate (NAA), choline-containing compounds and total creatine were similar in euthymic bipolar patients and healthy controls. Hippocampal glutamate concentrations were significantly increased as an effect of patient status (patients>controls) and laterality (left hippocampus>right hippocampus). Hippocampal glutamate content (Glu) was strongly correlated with NAA. Across groups and within the patient group, diurnal saliva cortisol levels showed a significant inverse relationship with both Glu and NAA. Taken together, these results add to the concept of bipolar disorder as an illness involving disturbed hippocampal structural plasticity under the opposing influences of lithium and glucocorticoids.

ADHD seriously impacts family functioning, even the more in families with simultaneous parental and child ADHD. The aim of the study was to examine associations between family impact of child ADHD and child, mother and family characteristics in multiplex families with children and mothers both affected by ADHD. One hundred and forty-four mother–child pairs were assessed (children: mean age 9.4 ± 1.7 years, 73.6 % male). Family impact of child ADHD was rated by mothers using the Family Impact Questionnaire (FIQ). Multiple linear regression analyses were performed with child and maternal psychopathology and basic family characteristics such as employment, partnership status and number of children as predictors and FIQ subscores as criteria. Rates of variance explained by family variables were 49 % for negative feelings towards the child, 37 % for impact on partnership, 31 % for impact on social life and 27 % for impact on finances (p < .001, respectively). Pearson correlations with family impact were especially strong for child externalizing symptoms, maternal ADHD and co-morbid symptoms of the mother. The strongest independent predictor was oppositional defiant child behaviour. In ADHD multiplex families, mothers’ perception of the impact of an ADHD child on its family can be explained to a substantial degree by child psychopathology, maternal psychopathology and basic family characteristics. Although a cross-sectional design does not allow for causal interpretations, the findings of this study offer important targets for the treatment of ADHD in a family context pointing to the need for assessing and treating parental mental health and co-morbid symptoms besides ADHD core symptoms.

Adult ADHD is a frequent psychiatric disorder affecting relevant aspects of an individual’s life. The aim of our study group was to carry out the first randomized controlled multicenter study to evaluate the effects of psychotherapy compared to clinical management in combination with psychopharmacological treatment with methylphenidate (MPH) or placebo (Plac) in a factorial four-arm design. Here, we present the enrollment procedure and description of adult ADHD patients recruited for the trial. Four hundred and thirty-three adult patients with ADHD were randomized at seven study sites in Germany to four treatment conditions: manualized dialectical-behavioral-therapy-based group psychotherapy (GPT) plus MPH or Plac, or clinical management (CM) including supportive counseling plus MPH or Plac with weekly sessions in the first 12 weeks and monthly sessions thereafter. Assessment for eligibility included standardized scales and instruments. After prescreening of 1,480 patients, 518 were evaluated for trial participation and 433 were randomized. The main reasons for prescreening failure were lack of interest in participating (n = 205), difficulties in meeting the time and effort requirements for participation (n = 186), and contraindications for psychopharmacological treatment with MPH (n = 194). The full analysis set (FAS) comprised 419 adult ADHD patients (mean age 35.2 years, males/females 1:1). Fifty-seven percent of the patients suffered from the combined ADHD subtype. Prevalence of at least one current or lifetime axis-I comorbidity was 66 %. Axis-II comorbidity rates was 18 % (patients with comorbid borderline and antisocial personality disorders were excluded). Our network was able to recruit an adult ADHD sample essentially comparable to community samples. A selection bias was created by excluding patients unable or unwilling to participate, or who had somatic and psychiatric contraindications for stimulant treatment (Current Controlled Trials ISRCTN54096201, Funding: Federal Ministry of Education and Research 01GV0606).

There is compelling evidence that depression constitutes an independent risk factor for cardiovascular morbidity and mortality. As exaggerated platelet reactivity is associated with an increased risk of intra-arterial thrombus formation, we studied platelet aggregability in patients with major depression both before and after 5 weeks of anti-depressant therapy as well as in healthy control subjects. Twenty-two depressed patients and 24 healthy control subjects participated in the study. Washed and rediluted platelets were stimulated with the agonists collagen and thrombin in three concentration steps. Depression was associated with a higher aggregability after stimulation with thrombin in the intermediate concentration and with collagen at the low concentration, with ceiling effects for the other concentrations. After 5 weeks of anti-depressant therapy, aggregability was somewhat less exaggerated, although this effect did not reach statistical significance. We thus conclude that major depression is associated with increased platelet aggregability, which seems to persist even under a marked improvement in depressive symptomatology. This effect may contribute to the increased cardiovascular morbidity in depressed patients.

There remains much scientific, clinical, and ethical controversy concerning the use of electroconvulsive therapy (ECT) for psychiatric disorders stemming from a lack of information and knowledge about how such treatment might work, given its nonspecific and spatially unfocused nature. The mode of action of ECT has even been ascribed to a “barbaric” form of placebo effect. Here we show differential, highly specific, spatially distributed effects of ECT on regional brain structure in two populations: patients with unipolar or bipolar disorder. Unipolar and bipolar disorders respond differentially to ECT and the associated local brain-volume changes, which occur in areas previously associated with these diseases, correlate with symptom severity and the therapeutic effect. Our unique evidence shows that electrophysical therapeutic effects, although applied generally, take on regional significance through interactions with brain pathophysiology.

Hyperactivity of the HPA-system in major depression is reflected by an increased secretion of adrenal hormones especially cortisol and dehydroepiandrosterone (DHEA). In women for whom androgenicity is associated with cardiovascular disorders the dominant source of androstenedione and testosterone secretion are the adrenal glands. To date, there is only sparse information about the regulation of androstenedione, testosterone and dihydrotestosterone (DHT) concentrations in women with severe major depression.Therefore, 11 pre- and postmenopausal, severely depressed, hypercortisolemic women (Hamilton Depression Scale, 31.3+/-5.9; age, 28-77 yrs; mean, 48. 1+/-18.1 yrs) and 11 age-matched healthy female controls (age, 24-81 yrs; mean, 47.9+/-21.5 yrs) underwent a 24 hour (h) blood sampling starting at 0800 h with 30-minute sampling intervals. By applying multivariate analysis of covariance with age as covariate, androstenedione, testosterone and DHT plasma levels at 0900 h show a trend for elevated concentrations in depressed women compared to controls (F(1,19)=2.7; P=0.057). Univariate F tests reveal a significant difference between the groups for androstenedione (4. 19+/-1.571 vs 2.584+/-1.257 nmol/l; P

Hippocampal mineralocorticoid (MRs) and glucocorticoid receptors (GRs) have been demonstrated to regulate the activity of the hypothalamus-pituitary-adrenocortical (HPA) system. To elucidate the role of the hippocampal MR in the circadian activity of the human HPA system, we studied diurnal secretory profiles of corticotropin (ACTH) and cortisol in 10 healthy male humans before and after an 8-day treatment with the MR antagonist spironolactone. 24-hour blood sampling at 30-min intervals was performed for estimation of cortisol (q30) and ACTH (q120). Saliva cortisol was measured for estimation of unbound cortisol. At the end of the 24-hour sampling period a corticotropin-releasing hormone (CRH) challenge was performed. High plasma concentrations of the active metabolite canrenone were achieved (begin of sampling: 2,653 ± 693 nmol/l; end of sampling: 747 ± 177 nmol/l). There was a significant increase in the diurnal minima (37.1 ± 13.3 vs. 23.7 ± 8.9 nmol/l, p < 0.02) and mean cortisol (193.5 ± 25.8 vs. 173.0 ± 23.0 nmol/l, p < 0.03) plasma concentrations. However, the diurnal peak concentrations and pulsatile secretory features were unchanged after spironolactone treatment. For saliva cortisol, the only significant treatment difference was a decrease in the diurnal amplitude of cortisol relative to the diurnal mean concentration (2.56 ± 0.47 vs. 3.11 ± 0.87, p < 0.03). After spironolactone treatment there was a decrease in diurnal mean ACTH concentrations (46.2 ± 14.4 vs. 41.8 ± 10.3 pmol/l). There was no difference in the ACTH and cortisol response after infusion of CRH before and after spironolactone treatment. CBG plasma concentrations were significantly increased (22.4 ± 2.3 vs. 19.2 ± 2.7 mg/l, p < 0.01) after spironolactone treatment, which possibly contributed to the observed increase in plasma cortisol. In summary, as predicted from animal studies we found significant effects of MR antagonization to be restricted to time windows of low HPA system activity. These findings are similar to the effects of aging upon the HPA system. However, the effect of spironolactone treatment was small, suggesting that the HPA system activity in humans is modulated but not regulated by the hippocampal MR.

Objective: The Conners Adult ADHD Rating Scales (CAARS) assess symptoms specific to adults that are frequently used and have been translated into German. The current study tests the factor structure of the CAARS in a large sample of German adults with ADHD and compares the means of the CAARS subscales with those of healthy German participants. Method: CAARS were completed by 466 participants with ADHD and 851 healthy control participants. Confirmatory factor analysis was used to establish model fit with the American original. Comparisons between participants with ADHD and healthy controls and influences of gender, age, and degree of education were analyzed. Results: Confirmatory factor analysis showed a very good fit with the model for the American original. Differences between ADHD participants and healthy controls on all Conners Adult ADHD Rating Scales–Self-Report (CAARS-S) subscales were substantial and significant. Conclusion: The factor structure of the original American model was successfully replicated in this sample of adult German ADHD participants.

The present study aimed to investigate glutamate concentrations in patients with unipolar depression in the midcingulate cortex (MCC) as compared to the left dorsolateral prefrontal cortex (DLPFC). We hypothesized a dissociation of glutamate levels with unchanged levels in DLPFC and abnormally changed levels in MCC as well as differential effects of antidepressant pharmacotherapy. Glutamate was determined using magnetic resonance spectroscopy at 3 T in DLPFC and MCC in fourteen depressed patients and matched healthy volunteers. A follow-up measurement was performed after 4 weeks of antidepressant treatment. The main finding is a region-specific pattern of glutamate concentrations with increased MCC glutamate concentrations and no significant differences in DLPFC glutamate concentrations in unipolar depressive patients compared to healthy controls. Response and non-response to antidepressant pharmacotherapy were predicted by high glutamate at baseline in DLPFC and MCC, respectively. In addition, treatment responders showed a further increase in DLPFC glutamate levels after successful antidepressant treatment. Findings indicate altered region-specific glutamate concentrations in DLPFC and MCC that are predictive of response and non-response, respectively, to antidepressant pharmacotherapy. These findings might serve as a starting point for future studies in which the value of this metabolite pattern for treatment response prediction should be investigated.

Background Subjects with Attention-Deficit Hyperactivity Disorder (ADHD) are overdistractible by stimuli out of the intended focus of attention. This control deficit could be due to primarily reduced attentional capacities or, e. g., to overshooting orienting to unexpected events. Here, we aimed at identifying disease-related abnormalities of novelty processing and, therefore, studied event-related potentials (ERP) to respective stimuli in adult ADHD patients compared to healthy subjects. Methods Fifteen unmedicated subjects with ADHD and fifteen matched controls engaged in a visual oddball task (OT) under simultaneous EEG recordings. A target stimulus, upon which a motor response was required, and non-target stimuli, which did not demand a specific reaction, were presented in random order. Target and most non-target stimuli were presented repeatedly, but some non-target stimuli occurred only once (‘novels’). These unique stimuli were either ‘relative novels’ with which a meaning could be associated, or ‘complete novels’, if no association was available. Results In frontal recordings, a positive component with a peak latency of some 400 ms became maximal after novels. In healthy subjects, this novelty-P3 (or ‘orienting response’) was of higher magnitude after complete than after relative novels, in contrast to the patients with an undifferentially high frontal responsivity. Instead, ADHD patients tended to smaller centro-parietal P3 responses after target signals and, on a behavioural level, responded slower than controls. Conclusion The results demonstrate abnormal novelty processing in adult subjects with ADHD. In controls, the ERP pattern indicates that allocation of meaning modulates the processing of new stimuli. However, in ADHD such a modulation was not prevalent. Instead, also familiar, only context-wise new stimuli were treated as complete novels. We propose that disturbed semantic processing of new stimuli resembles a mechanism for excessive orienting to commonly negligible stimuli in ADHD.

Studies in normal human subjects and animals suggest that the neuropeptide growth hormone-releasing hormone (GHRH) is a common regulator of the sleep EEG and nocturnal hormone secretion. In healthy volunteers GHRH prompts an increase in the amount of slow wave sleep (SWS) and in growth hormone (GH) secretion and blunting of cortisol release. Inhibition of GHRH may contribute to sleep-endocrine aberrances during depression. We tested the effects of pulsatile application of 4 x 50 μg GHRH on the sleep EEG and simultaneously investigated nocturnal hormone secretion in 10 inpatients (four females, six males) with the acute episode of major depression. In contrast to the effects of placebo, GH secretion increased distinctly and rapid-eye- movement (REM) density decreased during the second half of night. No other significant changes in sleep-endocrine activity, including SWS, cortisol and ACTH secretion, could be observed. We assume that hypothalamic-pituitary-adrenocortical system activity and slow wave sleep are inert to the influence of GHRH during acute depression. Cortisol and ACTH remained unchanged even in a subsample of five younger (aged 19–28 years) patients. This observation is in contrast to our recent finding that cortisol secretion is blunted in young normal volunteers after GHRH. But on the other hand, GHRH is capable of stimulating GH and inducing a decrease in REM density in these subjects.

BackgroundThe German version of the Conners Adult ADHD Rating Scales (CAARS) has proven to show very high model fit in confirmative factor analyses with the established factors inattention/memory problems, hyperactivity/restlessness, impulsivity/emotional lability, and problems with self-concept in both large healthy control and ADHD patient samples. This study now presents data on the psychometric properties of the German CAARS-self-report (CAARS-S) and observer-report (CAARS-O) questionnaires.MethodsCAARS-S/O and questions on sociodemographic variables were filled out by 466 patients with ADHD, 847 healthy control subjects that already participated in two prior studies, and a total of 896 observer data sets were available. Cronbach's-alpha was calculated to obtain internal reliability coefficients. Pearson correlations were performed to assess test-retest reliability, and concurrent, criterion, and discriminant validity. Receiver Operating Characteristics (ROC-analyses) were used to establish sensitivity and specificity for all subscales.ResultsCoefficient alphas ranged from .74 to .95, and test-retest reliability from .85 to .92 for the CAARS-S, and from .65 to .85 for the CAARS-O. All CAARS subscales, except problems with self-concept correlated significantly with the Barrett Impulsiveness Scale (BIS), but not with the Wender Utah Rating Scale (WURS). Criterion validity was established with ADHD subtype and diagnosis based on DSM-IV criteria. Sensitivity and specificity were high for all four subscales.ConclusionThe reported results confirm our previous study and show that the German CAARS-S/O do indeed represent a reliable and cross-culturally valid measure of current ADHD symptoms in adults.

Structural neuroimaging studies investigating amygdala volumes in patients suffering from major depression have yielded variable results. Discrepant findings across studies may be attributable in part to heterogeneity with respect to antidepressant medication and to lack of adequate control for the effects of total brain volume and age. Here, 24 unipolar depressed in-patients newly admitted to a psychiatric unit and 14 healthy control participants matched for age, gender, and years of education underwent quantitative magnetic resonance imaging (MRI) toward the end of a one-week washout period. Saliva cortisol was measured at 08.00 and at 16.00h in patients during washout. Absolute amygdala volumes were significantly reduced in the patient group (by 13% in left amygdala and 12% in right amygdala). The effect of reduced amygdala volumes in patients remained significant after correction for brain volume (BV) and age. Furthermore, amygdala volume measurements in the patient sample showed a significant inverse relationship to the number of preceding depressive episodes. In patients, severity of disease (baseline HAMD scores) and baseline cortisol levels were not related to amygdala volume. This study of a sample of unmedicated depressed in-patients adds to the small, yet growing, body of evidence linking untreated major depression to reduced amygdala volume.

Attention deficit hyperactivity disorder (ADHD) is a serious mental disorder that often persists in adulthood. In a pilot study, a structured skills training group program for adult ADHD led to significant symptomatic improvements. The present study evaluated the program's effectiveness, feasibility, and patient acceptability in a multicenter setting. Seventy-two adult ADHD patients were assigned to 13 two-hour weekly sessions at 4 different therapy sites. The therapy was well tolerated and led to significant improvements of ADHD, depressive symptoms, and personal health status (p < 0.001). The factors treatment site and medication did not contribute to the overall improvement. Patients regarded the program topics "behavioral analyses," "mindfulness," and "emotion regulation" as the most helpful. In this multicenter study, the therapy program showed therapist-independent effects and seemed to be disorder-specific. This warrants the effort of organizing further controlled studies.

The anterior cingulate cortex (ACC) is crucially involved in executive control of attention. Here, seven medication-naive adult patients suffering from attention deficit/hyperactivity disorder (ADHD) were studied with 2D (1)H-magnetic resonance spectroscopic imaging (MRSI) of the ACC [Brodmann areas 24b'-c' and 32'] twice, once before initiation of stimulant treatment and once after 5-6 weeks of methylphenidate. Upon retest, all patients demonstrated marked clinical improvement. Analysis of regional brain spectra revealed a significantly decreased signal of choline containing compounds as well as increased N-acetyl-aspartate (NAA) levels following treatment with methylphenidate whereas total creatine remained unchanged. Our results add to a growing body of evidence implicating the ACC in the pathophysiology of ADHD and suggest that subtle structural changes might be associated with aspects of clinical improvement under stimulant treatment.

The anterior cingulate cortex (ACC) plays a major role in modulating executive control of attention. Here, 15 medication-nai ve patients with attention deficit/hyperactivity disorder (ADHD) and 10 carefully matched healthy controls were studied with 2D (1)H-magnetic resonance spectroscopic imaging (MRSI) of the ACC [Brodmann areas 24b'-c' and 32']. Attentional skills were assessed using the identical pairs version of the continuous performance task (CPT-IP). Analysis of regional brain spectra revealed a significantly increased signal of choline-containing compounds (Ch) in the ACC of ADHD patients (p

Neuroimaging studies suggest a specific role of anterior cingulate cortex (ACC) and left dorsolateral prefrontal cortex (DLPFC) in major depression. Stimulation of the latter by means of repetitive transcranial magnetic stimulation (rTMS) as an antidepressant intervention has increasingly been investigated in the past. The objective of the present study was to examine in vivo neurochemical alterations in both brain regions in 17 patients with unipolar major depression before and after 10 days of high-frequency (20 Hz) rTMS of the left DLPFC using 3-tesla proton magnetic resonance spectroscopy. Six out of seventeen patients were treatment responders, defined as a 50% reduction of the Hamilton depression rating scale. No neurochemical alterations in the ACC were detected after rTMS. As compared to the non-responders, responders had lower baseline concentrations of DLPFC glutamate which increased after successful rTMS. Correspondingly, besides a correlation between clinical improvement and an increase in glutamate concentration, an interaction between glutamate concentration changes and stimulation intensity was observed. Our results indicate that metabolic, state-dependent changes within the left DLPFC in major depressive disorder involve the glutamate system and can be reversed in a dose-dependent manner by rTMS.

Objective To study, whether and how the results from open and double-blind randomized trials on antidepressants differ. Methods Seventy-one patients were included in a study comparing open, non-randomized, standardized treatment with paroxetine (PAROX) and amitriptyline (AMI) after a minimum of six drug-free days (OPEN). A second group of 56 patients received the same treatment under blind-randomized conditions (BLIND-RANDOM). The course of psychopathology as assessed by the Hamilton Depression Rating Scale was compared using repeated measurements ANOVA-(rm). Results While the rate of adverse events was higher in the BLIND-RANDOM compared to the OPEN condition, completer-analyses revealed no differences in psychopathological outcome. Conclusions With similar clinical outcome BLIND-RANDOM trials of antidepressants may expose depressed patients to an increased risk of adverse events, when compared to OPEN conditions. However, the clinical outcome in study completers did not differ between the BLIND-RANDOM and the OPEN condition. Thus, the psychiatrist's choice may have impact on adverse events rather than on clinical outcome of antidepressant treatment.

We hypothesized that the activity of the hypothalamus-pituitary-adrenal system in depressed patients is related to oral glucose tolerance. In 70 moderately depressed inpatients, we measured morning saliva cortisol for 6 days and assessed oral glucose tolerance. We found glucose concentrations to be positively associated with mean morning cortisol concentrations (F3,236 = 2.86, p < 0.05). Also, the ISI, a measure of insulin receptor sensitivity, was negatively associated with mean morning cortisol concentrations (r = –0.25, p < 0.04). These findings support the hypothesis that hypercortisolemia may lead to disturbed glucose utilization in depressed patients.

Steroid synthesis inhibitors are commonly used in the treatment of patients with Cushing's disease, but may also improve psychopathology in hypercortisolemic depressed patients. Since glucocorticoids exert a negative feedback at pituitary and supra-pituitary levels, the inhibition of steroid synthesis may lead to increased expression of corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP). We studied the effect of treatment with 800 mg ketoconazole (3 weeks) upon the concentrations of basal plasma cortisol in the evening, corticosteroid-binding globulin (CBG), dehydroepiandrosterone-sulfate (DHEA-S), and ACTH as well as the concentrations of cortisol, CRH, and AVP in cerebrospinal fluid (CSF) at 8.30 h in 10 healthy, male volunteers. While we found cortisol plasma concentrations to be unchanged, we noted a significant increase in ACTH (post: 45.1+/-43.5; pre: 14.2+/-5.2 pmol/l; F(1,8)=9.78, p
