ABSTRACT

OBJECTIVE: A considerable number of adolescents exhibit severe self-regulation deficits in affect and behavior, which are referred to as affective dysregulation (AD). AD may be conceptualized as a dimensional trait that, in its extreme form, resembles the diagnostic categories of severe mood dysregulation (SMD) or disruptive mood dysregulation disorder (DMDD). Assuming a shared pathway of psychopathology in AD and SMD, similar underlying dysfunctional mechanisms in emotion processing, particularly emotion recognition (RECOG) and regulation (REGUL), may be postulated. METHOD: Adolescent inpatients with AD (CAD, N = 35), without AD (CCG, N = 28), and nonclinical controls (NCG; N = 28) were administered a morphed facial recognition task (RECOG). REGUL abilities, levels of irritability as well as depressive symptoms were also assessed. RESULTS: We found no significant group differences in accuracy and thresholds for RECOG abilities. Patients with AD reported more dysfunctional REGUL strategies than did CCG and NCG. Both depression and AD, but not irritability, influenced the overall degree of maladaptive REGUL. CONCLUSION: The broad phenotype of AD does not involve the deficits in RECOG reported for adolescents with a narrow phenotype (SMD); regarding REGUL strategies, AD seems to be associated with specific impairments.

ABSTRACT

Background: Neurofeedback (NF) in children with attention-deficit/hyperactivity disorder (ADHD) has been investigated in a series of studies over the last years. Previous studies did not unanimously support NF as a treatment in ADHD. Most studies did not control for unspecific treatment effects and did not demonstrate that self-regulation took place. The present study examined the efficacy of NF in comparison to electromyographic (EMG) feedback to control for unspecific effects of the treatment, and assessed self-regulation of slow cortical potentials (SCPs). Methods: A total of 150 children aged 7-9 years diagnosed with ADHD (82% male; 43% medicated) were randomized to 25 sessions of feedback of SCPs (NF) or feedback of coordination of the supraspinatus muscles (EMG). The primary endpoint was the change in parents' ratings of ADHD core symptoms 4 weeks after the end of treatment compared to pre-tests. Results: Children in both groups showed reduced ADHD-core symptoms (NF 0.3, 95% CI -0.42 to -0.18; EMG 0.13, 95% CI -0.26 to -0.01). NF showed a significant superiority over EMG (treatment difference 0.17, 95% CI 0.02-0.3, p = 0.02). This yielded an effect size (ES) of d = 0.57 without and 0.40 with baseline observation carried forward (BOCF). The sensitivity analysis confirmed the primary result. Successful self-regulation of brain activity was observed only in NF. As a secondary result teachers reported no superior improvement from NF compared to EMG, but within-group analysis revealed effects of NF on the global ADHD score, inattention, and impulsivity. In contrast, EMG feedback did not result in changes despite more pronounced self-regulation learning. Conclusions: Based on the primary parent-rated outcome NF proved to be superior to a semi-active EMG feedback treatment. The study supports the feasibility and efficacy of NF in a large sample of children with ADHD, based on both specific and unspecific effects. Trial Register: Current controlled trials ISRCTN76187185, registered 5 February 2009.

ABSTRACT

Chronotherapeutics such as wake therapy and bright light therapy are well-established methods in treating adults with depressive disorders and are additionally beneficent for sleep regulation. Few studies concerning chronotherapeutics in juvenile depression exist, though the established treatments are insufficient and sleep disorders often co-occur. In this study, we investigate the impact of two types of chronotherapeutics on depressive symptoms and sleep behavior in a juvenile setting. Juvenile inpatients (n = 62) with moderate to severe depressive symptoms took part in either a combined setting consisting of one night wake therapy followed by 2 weeks bright light therapy or in a setting of bright light therapy alone. Depressive symptoms, general psychopathology, clinical impression and sleep behavior were measured before (T1), directly after (T2) and 2 weeks after intervention (T3). Depressive symptoms decreased while sleep quality increased in both groups. The bright light therapy alone group showed further improvement at T3 in regards to depressive symptoms. Correlation analyses indicated significant negative correlations between sleep quality and awaking after restorative sleep with the depressive symptoms. However, only awaking after restorative sleep had a predictive impact on treatment outcome. The present study provides first evidence for a positive impact of chronotherapeutic interventions on treatment outcome in depressed juvenile inpatients. Bright light therapy seems to stabilize and further enhance reduction of depressive symptoms during follow-up, whereas one night wake therapy does not have an additional long-lasting impact on depressive symptoms and sleep parameters.

ABSTRACT

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is the most common neurobehavioral disorder of childhood and has often a chronic course persisting into adulthood. However, up to 30% of children treated with stimulants either fail to show an improvement or suffer adverse side effects, including decreased appetite, insomnia and irritability and there is no evidence of long term efficacy of stimulants for ADHD. A series of studies has shown that neurofeedback is an effective additional or alternative treatment for children with ADHD, leading to e.g. significant and stable improvement in behavior, attention and IQ. Significant treatment effects of neurofeedback have also been verified in meta-analyses. Most of the trials, however, have been criticized for methodological difficulties, particularly lacking appropriate control conditions and number of patients included. This randomized study examines the efficacy of slow cortical potentials (SCP) -neurofeedback, controlling unspecific effects of the setting by comparing two active treatment modalities. METHODS/DESIGN: A total of 144 patients with ADHD, older than six and younger than ten years, in some cases with additional pharmacological treatment, are included in this trial. In five trial centres patients are treated either with SCP-feedback or electromyographic (EMG) -feedback in 25 sessions within 3 months. A comprehensive test battery is conducted before and after treatment and at follow-up 6 month later, to assess core symptoms of ADHD, general psychopathology, attentional performance, comorbid symptoms, intelligence, quality of life and cortical arousal. DISCUSSION: The efficacy of SCP-feedback training for children with ADHD is evaluated in this randomized controlled study. In addition to behavior ratings and psychometric tests neurophysiological parameters serve as dependent variables. Further, the choice of EMG-biofeedback as an active control condition is debated.

ABSTRACT

Chronotherapeutic treatments, such as bright light therapy, sleep deprivation and sleep phase advance have successfully been established for the treatment of adults with seasonal and major depression. Today, sleep deprivation is supposed to be the fastest acting antidepressant we know of. Combined with bright light therapy, the antidepressive effect can be sustained. Notwithstanding, the effect of sleep deprivation and bright light therapy has not yet been studied in adolescents suffering from juvenile depression. However, because of its growing prevalence rates and the insufficient outcomes of established treatments, such as medication and psychotherapy, alternative treatments of juvenile depression are urgently needed. Furthermore, a high percentage of patients suffer from sleep disorders. Along with their large positive impact on sleep patterns and antidepressive effects, chronotherapeutics are thought to be powerful interventions for patients with juvenile depression. The present study investigates the additional benefit of sleep deprivation combined with bright light therapy, as compared to mere bright light therapy. We hypothesize that both therapies have a positive impact on depressive symptoms and sleep parameters, but that a combined therapy enhances and sustains outcomes.
