Electroconvulsive therapy-induced volumetric brain changes converge on a common causal circuit in depression.

Neurostimulation is a mainstream treatment option for major depression. Neuromodulation techniques apply repetitive magnetic or electrical stimulation to some neural target but significantly differ in their invasiveness, spatial selectivity, mechanism of action, and efficacy. Despite these differences, recent analyses of transcranial magnetic stimulation (TMS) and deep brain stimulation (DBS)-treated individuals converged on a common neural network that might have a causal role in treatment response. We set out to investigate if the neuronal underpinnings of electroconvulsive therapy (ECT) are similarly associated with this causal depression network (CDN). Our aim here is to provide a comprehensive analysis in three cohorts of patients segregated by electrode placement (N = 246 with right unilateral, 79 with bitemporal, and 61 with mixed) who underwent ECT. We conducted a data-driven, unsupervised multivariate neuroimaging analysis Principal Component Analysis (PCA) of the cortical and subcortical volume changes and electric field (EF) distribution to explore changes within the CDN associated with antidepressant outcomes. Despite the different treatment modalities (ECT vs TMS and DBS) and methodological approaches (structural vs functional networks), we found a highly similar pattern of change within the CDN in the three cohorts of patients (spatial similarity across 85 regions: r = 0.65, 0.58, 0.40, df = 83). Most importantly, the expression of this pattern correlated with clinical outcomes (t = -2.35, p = 0.019). This evidence further supports that treatment interventions converge on a CDN in depression. Optimizing modulation of this network could serve to improve the outcome of neurostimulation in depression.

Augmenting the unified protocol with transcranial direct current stimulation: Effects on emotion regulation and executive dysfunction.

The aim of the current study was to compare the unified protocol for transdiagnostic treatment of emotional disorders (UP) with and without transcranial direct current stimulation (tDCS) for the treatment of emotion regulation and executive control dysfunction in individuals diagnosed with generalized anxiety disorder (GAD) and comorbid major depressive disorder (MDD). A total of 43 individuals with GAD and co-morbid MDD were randomly assigned to three groups including UP with tDCS (UP+tDCS; n = 15), UP alone (UP; n = 13) or wait-list control (n = 15). Difficulties in emotion regulation, reappraisal, suppression, inhibition and working memory were assessed at baseline, post-treatment and 3-month follow-up. Treatment with both UP+tDCS and UP alone resulted in significant improvements in difficulties in emotion regulation, cognitive reappraisal, and working memory, and significant reductions in suppression and inhibition relative to wait-list controls at post-treatment and 3-month follow-up. Relative to UP alone, UP+tDCS showed significantly greater improvements in difficulties in emotion regulation, cognitive reappraisal, inhibition, and working memory at post-treatment and 3-month follow-up. These results suggest combination of UP treatment with tDCS may be an efficacious intervention to improve emotion regulation and executive function in GAD with co-morbid MDD.

Neural correlates of learning accommodation and consolidation in generalised anxiety disorder.

OBJECTIVE.: Anxiety can interfere with attention and working memory, which are components that affect learning. Statistical models have been designed to study learning, such as the Bayesian Learning Model, which takes into account prior possibilities and behaviours to determine how much of a new behaviour is determined by learning instead of chance. However, the neurobiological basis underlying how anxiety interferes with learning is not yet known. Accordingly, we aimed to use neuroimaging techniques and apply a Bayesian Learning Model to study learning in individuals with generalised anxiety disorder (GAD). METHODS.: Participants were 25 controls and 14 individuals with GAD and comorbid disorders. During fMRI, participants completed a shape-button association learning and reversal task. Using a flexible factorial analysis in SPM, activation in the dorsolateral prefrontal cortex, basal ganglia, and hippocampus was compared between groups during first reversal. Beta values from the peak of these regions were extracted for all learning conditions and submitted to repeated measures analyses in SPSS. RESULTS.: Individuals with GAD showed less activation in the basal ganglia and the hippocampus only in the first reversal compared with controls. This difference was not present in the initial learning and second reversal. CONCLUSION.: Given that the basal ganglia is associated with initial learning, and the hippocampus with transfer of knowledge from short- to long-term memory, our results suggest that GAD may engage these regions to a lesser extent during early accommodation or consolidation of learning, but have no longer term effects in brain activation patterns during subsequent learning.

Deficits in frontoparietal activation and anterior insula functional connectivity during regulation of cognitive-affective interference in bipolar disorder.

OBJECTIVES: Bipolar disorders (BD) are characterized by emotion and cognitive dysregulation. Mapping deficits in the neurocircuitry of cognitive-affective regulation allows for potential identification of intervention targets. This study used functional MRI data in BD patients and healthy controls during performance on a task requiring cognitive and inhibitory control superimposed on affective images, assessing cognitive and affective interference. METHODS: Functional MRI data were collected from 39 BD patients and 36 healthy controls during performance on the Multi-Source Interference Task overlaid on images from the International Affective Picture System (MSIT-IAPS). Analyses examined patterns of activation in a priori regions implicated in cognitive and emotional processing. Functional connectivity to the anterior insula during task performance was also examined, given this region's role in emotion-cognition integration. RESULTS: BD patients showed significantly less activation during cognitive interference trials in inferior parietal lobule, dorsomedial prefrontal cortex, anterior insula, mid-cingulate, and ventrolateral prefrontal cortex regardless of affective valence. BD patients showed deviations in functional connectivity with anterior insula in regions of the default mode and frontoparietal control networks during negatively valenced cognitive interference trials. CONCLUSIONS: Our findings show disruptions in cognitive regulation and inhibitory control in BD patients in the presence of irrelevant affective distractors. Results of this study suggest one pathway to dysregulation in BD is through inefficient integration of affective and cognitive information, and highlight the importance of developing interventions that target emotion-cognition integration in BD.

Predicting Dimensional Antidepressant Response to Repetitive Transcranial Magnetic Stimulation using Pretreatment Resting-state Functional Connectivity.

Repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for depression and has been shown to modulate resting-state functional connectivity (RSFC) of depression-relevant neural circuits. To date, however, few studies have investigated whether individual treatment-related symptom changes are predictable from pretreatment RSFC. We use machine learning to predict dimensional changes in depressive symptoms using pretreatment patterns of RSFC. We hypothesized that changes in dimensional depressive symptoms would be predicted more accurately than scale total scores. Patients with depression (n=26) underwent pretreatment RSFC MRI. Depressive symptoms were assessed with the 17-item Hamilton Depression Rating Scale (HDRS-17). Random forest regression (RFR) models were trained and tested to predict treatment-related symptom changes captured by the HDRS-17, HDRS-6 and three previously identified HDRS subscales: core mood/anhedonia (CMA), somatic disturbances, and insomnia. Changes along the CMA, HDRS-17, and HDRS-6 were predicted significantly above chance, with 9%, 2%, and 2% of out-of-sample outcome variance explained, respectively (all p<0.01). CMA changes were predicted more accurately than the HDRS-17 (p<0.05). Higher baseline global connectivity (GC) of default mode network (DMN) subregions and the somatomotor network (SMN) predicted poorer symptom reduction, while higher GC of the right dorsal attention (DAN) frontoparietal control (FPCN), and visual networks (VN) predicted reduced CMA symptoms. HDRS-17 and HDRS-6 changes were predicted with similar GC patterns. These results suggest that RSFC spanning the DMN, SMN, DAN, FPCN, and VN subregions predict dimensional changes with greater accuracy than syndromal changes following rTMS. These findings highlight the need to assess more granular clinical dimensions in therapeutic studies, particularly device neuromodulation studies, and echo earlier studies supporting that dimensional outcomes improve model accuracy.

Brain volumetric correlates of electroconvulsive therapy versus transcranial magnetic stimulation for treatment-resistant depression.

BACKGROUND: Electroconvulsive therapy (ECT) and repetitive transcranial magnetic stimulation (rTMS) are effective neuromodulation therapies for treatment-resistant depression (TRD). While ECT is generally considered the most effective antidepressant, rTMS is less invasive, better tolerated and leads to more durable therapeutic benefits. Both interventions are established device antidepressants, but it remains unknown if they share a common mechanism of action. Here we aimed to compare the brain volumetric changes in patients with TRD after right unilateral (RUL) ECT versus left dorsolateral prefrontal cortex (lDLPFC) rTMS. METHODS: We assessed 32 patients with TRD before the first treatment session and after treatment completion using structural magnetic resonance imaging. Fifteen patients were treated with RUL ECT and seventeen patients received lDLPFC rTMS. RESULTS: Patients receiving RUL ECT, in comparison with patients treated with lDLPFC rTMS, showed a greater volumetric increase in the right striatum, pallidum, medial temporal lobe, anterior insular cortex, anterior midbrain, and subgenual anterior cingulate cortex. However, ECT- or rTMS-induced brain volumetric changes were not associated with the clinical improvement. LIMITATIONS: We evaluated a modest sample size with concurrent pharmacological treatment and without neuromodulation therapies randomization. CONCLUSIONS: Our findings suggest that despite comparable clinical outcomes, only RUL ECT is associated with structural change, while rTMS is not. We hypothesize that structural neuroplasticity and/or neuroinflammation may explain the larger structural changes observed after ECT, whereas neurophysiological plasticity may underlie the rTMS effects. More broadly, our results support the notion that there are multiple therapeutic strategies to move patients from depression to euthymia.

Closed-loop enhancement and neural decoding of cognitive control in humans.

Deficits in cognitive control-that is, in the ability to withhold a default pre-potent response in favour of a more adaptive choice-are common in depression, anxiety, addiction and other mental disorders. Here we report proof-of-concept evidence that, in participants undergoing intracranial epilepsy monitoring, closed-loop direct stimulation of the internal capsule or striatum, especially the dorsal sites, enhances the participants' cognitive control during a conflict task. We also show that closed-loop stimulation upon the detection of lapses in cognitive control produced larger behavioural changes than open-loop stimulation, and that task performance for single trials can be directly decoded from the activity of a small number of electrodes via neural features that are compatible with existing closed-loop brain implants. Closed-loop enhancement of cognitive control might remediate underlying cognitive deficits and aid the treatment of severe mental disorders.

Most importantly, the expression of this pattern correlated with clinical outcomes. This evidence further supports that treatment interventions converge on a CCN in depression. Optimizing modulation of this network could serve to improve the outcome of neurostimulation in depression.

Neurobiological correlates of cognitions in fear and anxiety: a cognitive-neurobiological information-processing model.

We review likely neurobiological substrates of cognitions related to fear and anxiety. Cognitive processes are linked to abnormal early activity reflecting hypervigilance in subcortical networks involving the amygdala, hippocampus, and insular cortex, and later recruitment of cortical regulatory resources, including activation of the anterior cingulate cortex and prefrontal cortex to implement avoidant response strategies. Based on this evidence, we present a cognitive-neurobiological information-processing model of fear and anxiety, linking distinct brain structures to specific stages of information processing of perceived threat.

Electroconvulsive therapy effects on anhedonia and reward circuitry anatomy: A dimensional structural neuroimaging approach.

BACKGROUND: Anhedonia is a core symptom of major depressive disorder (MDD) resulting from maladaptive reward processing. Electroconvulsive therapy (ECT) is an effective treatment for patients with MDD. No previous neuroimaging studies have taken a dimensional approach to assess whether ECT-induced volume changes are specifically related to improvements in anhedonia and positive valence emotional constructs. We aimed to assess the relationship between ECT-induced brain volumetric changes and improvement in anhedonia and reward processing in patients with MDD. METHODS: We evaluated 15 patients with MDD before and after ECT. We used magnetic resonance imaging, clinical scales (i.e., Quick Inventory of Depressive Symptomatology for syndromal depression severity and Snaith-Hamilton Pleasure Scale for anhedonia) and the Temporal Experience of Pleasure Scale for anticipatory and consummatory experiences of pleasure. We identified 5 regions of interest within the reward circuit and a 6th control region relevant for MDD but not core to the reward system (Brodmann Area 25). RESULTS: Anhedonia, anticipatory and consummatory reward processing improved after ECT. Volume increases within the right reward system separated anhedonia responders and non-responders. Improvement in anticipatory (but not consummatory) reward correlated with increases in volume in hippocampus, amygdala, ventral tegmental area and nucleus accumbens. LIMITATIONS: We evaluated a modest sample size of patients with concurrent pharmacological treatment using a subjective psychometric assessment. CONCLUSIONS: We highlight the importance of a dimensional and circuit-based approach to understanding target engagement and the mechanism of action of ECT, with the goal to define symptom- and circuit-specific response biomarkers for device neuromodulation therapies.

Convergence between behavioral, neural, and self-report measures of cognitive control: The Frontal Systems Behavior Scale in bipolar disorder.

The Frontal Systems Behavior Scale (FrSBe) is a self-report measure that assesses difficulties with cognitive and emotional control such as apathetic behavior, lack of inhibitory control, and executive dysfunction. Previous neuroimaging studies highlight the involvement of the anterior cingulate cortex (ACC), orbitofrontal cortex (OFC), and dorsolateral prefrontal cortex (DLPFC) in these processes. In this study, we investigated whether there was convergence across subjective and objective measures of apathy, disinhibition, and executive dysfunction. Specifically, we studied whether ACC, OFC, and DLPFC activation during a modified version of the Multi-Source Interference Task (MSIT), is associated with FrSBe apathy, disinhibition, and executive dysfunction scores, in healthy controls (HC) and individuals with Bipolar Disorder (BD), who commonly exhibit difficulties in these domains. Individuals with BD (n = 31) and HCs (n = 31) with no current or past psychiatric illness completed the FrSBe and the MSIT during fMRI scanning. We investigated task-specific changes in the ACC, DLPFC, and OFC and their correlations with FrSBe apathy, disinhibition, and executive dysfunction subscale scores, respectively. Individuals with BD and the HC group demonstrated greater ACC, DLPFC, and OFC activation during MSIT interference conditions compared with non-interference conditions. Furthermore, there was a significant negative correlation between OFC activation and disinhibition scores, which remained significant after accounting for medication load. Together, these results demonstrate the FrSBe disinhibition subscale, in particular, can be a self-report measure that converges with behavioral and neural markers of disinhibition in BD.

Dimensional Affective Processing in BD.

Bipolar Disorder (BD) involves altered neural affective processing, but studies comparing BD patients to controls have yielded inconsistent results. This might relate to substantial variability in the nature and severity of mood symptoms among individuals with BD. Hence, we dimensionally examined the relationship between depressive and manic symptom severity and neural responses to positive and negative affective stimuli. 39 Participants with BD completed measures of depression and mania severity prior to completing a cognitive-affective processing task during fMRI. A multiple regression model was run in SPM to identify brain regions correlated with depressive and manic symptoms during positive-neutral and negative-neutral contrasts. A-priori anatomical ROIs were defined bilaterally in frontal, parietal and limbic regions. Results showed that depression severity was associated with increased activation in frontal, parietal, and limbic ROIs, regardless of valence. Mania severity was correlated with both increased and decreased activation, particularly within frontal subdivisions and during the processing of positively valenced images. In conclusion, dimensional modeling of symptom severity captures variance in neural responses to affect, which may have been previously undetected due to heterogeneity when examined at the group level. Future fMRI studies comparing BD patients and controls should account for symptom variability in BD.

Conceptual background, development, and preliminary data from the unified protocol for transdiagnostic treatment of emotional disorders.

Anxiety and mood disorders are common, chronic, costly, and characterized by high comorbidity. The development of cognitive behavioral approaches to treating anxiety and mood disorders has left us with highly efficacious treatments that are increasingly widely accepted. The proliferation of treatment manuals targeting single disorders, sometimes with trivial differences among them, leaves the mental health professional with no clear way to choose one manual over another and little chance of ever becoming familiar with most of them, let alone trained to competence in their delivery. Deepening understanding of the nature of emotional disorders reveals that commonalities in etiology and latent structures among these disorders supersedes differences. Based on empirical evidence from the domains of learning, emotional development and regulation, and cognitive science, we have distilled a set of psychological procedures that comprise a unified intervention for emotional disorders. The Unified Protocol (UP) is a transdiagnostic, emotion-focused cognitive behavioral treatment, which emphasizes the adaptive, functional nature of emotions, and seeks to identify and correct maladaptive attempts to regulate emotional experiences, thereby facilitating appropriate processing and extinction of excessive emotional responding to both internal (somatic) and external cues. The treatment components of the UP are briefly outlined. Theory and rationale supporting this new approach are described along with some preliminary evidence supporting its efficacy. Implications for the treatment of emotional disorders using the UP are discussed.

The Development of the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders: A Case Study.

A detailed description of treatment utilizing the Unified Protocol (UP), a transdiagnostic emotion-focused cognitive-behavioral treatment, is presented using a clinical case example treated during the most current phase of an ongoing randomized controlled trial of the UP. The implementation of the UP in its current, modular version is illustrated. A working case conceptualization is presented from the perspective of the UP drawing from theory and research that underlies current transdiagnostic approaches to treatment and consistent with recent dimensional classification proposals (Brown & Barlow, in press). Treatment is illustrated module-by-module describing how the principles of the UP were applied in the presented case.

Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders: Protocol Development and Initial Outcome Data.

Two studies present preliminary support for the Unified Protocol (UP), a transdiagnostic, emotion-focused cognitive-behavioral treatment developed to be applicable across the emotional disorders. Study 1 presents data from an open clinical trial of the initial version of the UP in a heterogeneous clinical sample, yielding large pre- to post-treatment effect sizes across disorders on measures of DSM-IV diagnostic category severity, and medium to large effect sizes on general measures of depression and anxiety, social adjustment, and levels of negative and positive affect. Following a period of further manual development resulting in specific modifications and enhancements to core treatment components, Study 2 presents data from an additional pilot study of this revised version of the UP. Results from Study 2 demonstrated more robust treatment effect sizes and greater changes across measures of depression, anxiety, positive and negative affect, social adjustment, and quality of life. Relatively similar treatment effects were again demonstrated across a full range of anxiety and mood disorders, suggesting roughly equivalent transdiagnostic efficacy. Implications for the treatment of emotional disorders, clinical practice, and dimensional conceptualizations of psychopathology are discussed.

Augmenting the unified protocol for transdiagnostic treatment of emotional disorders with transcranial direct current stimulation in individuals with generalized anxiety disorder and comorbid depression: A randomized controlled trial.

BACKGROUND: The aim of the current study was to compare the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) with and without transcranial direct current stimulation (tDCS) in individuals suffering from generalized anxiety disorder (GAD) and comorbid depression. METHODS: A total of 43 individuals diagnosed with GAD and comorbid depression enrolled in a randomized controlled trial (IRCT20140929019334N1). Participants were randomly assigned to three groups including UP with tDCS (UP+tDCS; n = 15), UP alone (UP; n = 13) or wait-list control (n = 15). GAD and depression symptoms, worry severity, anxiety sensitivity, and intolerance of uncertainty were assessed at baseline, post-treatment and 3-month follow-up. RESULTS: Treatment with both UP+tDCS and UP alone resulted in significant lower ratings across all measures relative to wait-list controls at post-treatment and 3-month follow-up (all p-values <0.001). UP+tDCS showed significantly greater reductions in anxiety (p = 0.001 post-treatment; p = 0.003 follow-up), worry (p = 0.001 post-treatment; p = 0.002 follow-up), and anxiety sensitivity (p = 0.003 post-treatment; p = 0.002 follow-up) relative to UP alone. LIMITATIONS: The present study had some limitations. First, the sample size was low. Another limitation was the use of a short-term follow-up. CONCLUSIONS: These results suggest augmenting UP treatment with tDCS may be an efficacious strategy to improve treatment outcomes in GAD with comorbid depression. Trial registration reference is IRCT20140929019334N1 (see https://irct.ir/trial/27988).

Neural correlates of the ADHD self-report scale.

BACKGROUND: The ADHD Self Report Scale is a self-report measure that assesses attentional problems. We sought to validate the ASRS by establishing neural correlates using functional magnetic imaging in healthy controls and individuals with bipolar disorder (BD), who commonly exhibit attentional problems. METHODS: ASRS questionnaires and functional MRI data in conjunction with the Multi-source Interference Task (MSIT) were collected from 36 healthy control and 36 BD participants. We investigated task specific changes in the dorsal anterior cingulate cortex (dACC, Brodmann area 32) and their correlations with ASRS subscale scores, inattention and hyperactivity, in both cohorts. RESULTS: As hypothesized, the dACC showed significant increases in BOLD activation between the interference and noninterference conditions. For the ASRS scale as well as its Inattention and Hyperactivity subscales, there was a significant negative correlation with the dACC BOLD for the whole group. CONCLUSIONS: The ASRS is sensitive to attentional difficulties in BD, suggesting that it is a valid tool for assessing attentional difficulties in patients with BD.

Feasibility and Acceptability of a Lifestyle Intervention For Individuals With Bipolar Disorder.

Individuals with bipolar disorder are at greater risk for cardiovascular disease and are less likely to adhere to lifestyle interventions than the general population. To decrease cardiovascular risk and improve adherence to lifestyle interventions, we developed the Nutrition Exercise and Wellness Treatment (NEW Tx). NEW Tx is an 18-session, 20-week cognitive behavioral therapy-based treatment comprising 3 modules: Nutrition, Exercise, and Wellness. To evaluate the feasibility and acceptability of this intervention as well as predictors of treatment satisfaction and expectations, 38 adult outpatients with bipolar disorder were randomized to either NEW Tx or a waitlist control condition. There was no statistically significant difference in dropout rates between the groups (26.3% in NEW Tx, 31.6% in the control condition). In the NEW Tx condition, participants attended a mean of 66.7% of sessions and reported moderate to high satisfaction. There were no study-related adverse events. We also found that expectations, but not perceived credibility (or believability), of NEW Tx (as measured by the Credibility/Expectancy Questionnaire) at baseline predicted treatment satisfaction (as measured by the Care Satisfaction Questionnaire) posttreatment. Manic symptoms at baseline predicted treatment satisfaction, and marital status predicted one's expectations of lifestyle interventions. Data suggest that NEW Tx is a feasible and acceptable intervention for individuals with bipolar disorder and that further research is warranted to explore potential moderators of treatment expectations and credibility in this clinical population.

Pilot study of a lifestyle intervention for bipolar disorder: Nutrition exercise wellness treatment (NEW Tx).

BACKGROUND: Individuals with bipolar disorder (BD) are more likely than the general population to develop risk factors associated with cardiovascular disease, one of the leading causes of morbidity and mortality in this clinical population. To address this disproportionate medical burden, we developed Nutrition Exercise and Wellness Treatment (NEW Tx), a lifestyle intervention for individuals with BD. METHODS: In this study, participants were randomized to NEW Tx (n = 19) or a treatment as usual waitlist (n = 19). We examine the intervention's efficacy to improve the physical and psychological outcomes of individuals with BD. Assessors were blind to participant condition throughout study duration. RESULTS: The NEW Tx group reported increased weekly exercise duration and overall functioning, and decreased depression and illness severity over the study duration. However, only improvements in functioning were significantly greater in the NEW Tx group than in the control group. There were no group differences in weight loss or mood symptoms over the study duration. LIMITATIONS: Limitations to this study include lack of objective measurement of exercise and a small and relatively homogeneous sample. CONCLUSIONS: These data suggest that a manualized lifestyle intervention for BD may not be ideal to improve lifestyle changes in this clinical population. Further research is needed to pilot personalized approaches to creating a healthy lifestyle in BD.
