RESUMEN

BACKGROUND: Abnormalities in dopamine and norepinephrine signaling are implicated in cognitive impairments in bipolar disorder (BD) and attention-deficit hyperactivity disorder (ADHD). This systematic review by the ISBD Targeting Cognition Task Force therefore aimed to investigate the possible benefits on cognition and/or ADHD symptoms and safety of established and off-label ADHD therapies in BD. METHODS: We included studies of ADHD medications in BD patients, which involved cognitive and/or safety measures. We followed the procedures of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 statement. Searches were conducted on PubMed, Embase and PsycINFO from inception until June 2023. Two authors reviewed the studies independently using the Revised Cochrane Collaboration's Risk of Bias tool for Randomized trials. RESULTS: Seventeen studies were identified (N = 2136), investigating armodafinil (k = 4, N = 1581), methylphenidate (k = 4, N = 84), bupropion (k = 4, n = 249), clonidine (k = 1, n = 70), lisdexamphetamine (k = 1, n = 25), mixed amphetamine salts (k = 1, n = 30), or modafinil (k = 2, n = 97). Three studies investigated cognition, four ADHD symptoms, and 10 the safety. Three studies found treatment-related ADHD symptom reduction: two involved methylphenidate and one amphetamine salts. One study found a trend towards pro-cognitive effects of modafinil on some cognitive domains. No increased risk of (hypo)mania was observed. Five studies had low risk of bias, eleven a moderate risk, and one a serious risk of bias. CONCLUSIONS: Methylphenidate or mixed amphetamine salts may improve ADHD symptoms in BD. However, there is limited evidence regarding the effectiveness on cognition. The medications produced no increased mania risk when used alongside mood stabilizers. Further robust studies are needed to assess cognition in BD patients receiving psychostimulant treatment alongside mood stabilizers.

RESUMEN

BACKGROUND: Cognitive impairment is a core feature of mood disorders and has been identified as an important treatment target. A better understanding of the factors contributing to cognitive impairment in mood disorders would be beneficial in developing interventions to address cognitive impairment. One key factor is childhood trauma. The aim of this review was to systematically synthesise and review research examining associations between reported childhood trauma and cognitive functioning in mood disorders. METHODS: Studies in adult samples examining the relationship between objective cognitive function and reported childhood trauma in major depressive disorder and/or bipolar disorder (in-episode or euthymia) were identified. Searches were conducted on PubMed, Embase and PsycINFO until January 2022. A narrative review technique was used due to the heterogeneity of group comparisons, cognitive tests and data analysis across studies. RESULTS: Seventeen studies met the criteria for inclusion (mood disorders N = 1723, healthy controls N = 797). Evidence for childhood trauma being related to poorer cognitive functioning was consistent across global cognitive functioning and executive function domains for euthymic patients and psychomotor speed for in-episode patients. There was mixed evidence for verbal learning and memory and executive function for in-episode patients. Identification of patterns within other domains was difficult due to limited number of studies. CONCLUSION: Findings from this review suggest childhood trauma is associated with poorer cognitive functioning in people with mood disorders. Targeted interventions to improve cognition may be warranted for this group.

RESUMEN

BACKGROUND: There is evidence of disparities between non-Indigenous and Indigenous incidence of psychotic disorders. Despite these disparities being a clear signpost of the impact of structural racism, there remains a lack of evidence to target institutional factors. We aimed to investigate non-Indigenous and Indigenous differences in government service use prior to first episode diagnosis as a means of identifying points of intervention to improve institutional responses. METHODS: We used a previously established national New Zealand cohort of 2385 13 to 25-year-old youth diagnosed with psychosis between 2009 and 2012 and a linked database of individual-level multiple government agency administration data, to investigate the differences in health, education, employment, child protection and criminal-justice service use between non-Indigenous (60%) and Indigenous youth (40%) in the year preceding first episode diagnosis. Further comparisons were made with the general population. RESULTS: A high rate of health service contact did not differ between non-Indigenous and Indigenous youth (adjusted rate ratio 1.0, 95% confidence interval [0.9, 1.1]). Non-Indigenous youth had higher rates of educational enrolment (adjusted rate ratio 1.2, 95% confidence interval [1.1, 1.3]) and employment (adjusted rate ratio 1.2, 95% confidence interval [1.1, 1.3]) and were 40% less likely to have contact with child protection services (adjusted rate ratio 0.6, 95% confidence interval [0.5, 0.8]) and the criminal-justice system (adjusted rate ratio 0.6, 95% confidence interval [0.5, 0.7]). Both first episode cohorts had a higher risk of criminal justice contact compared to the general population, but the difference was greater for non-Indigenous youth (risk ratio 3.0, 95% confidence interval [2.7, 3.4] vs risk ratio 2.0, 95% confidence interval [1.8, 2.2]), explained by the lower background risk. INTERPRETATION: The results indicate non-Indigenous privilege in multiple sectors prior to first episode diagnosis. Indigenous-based social disparities prior to first episode psychosis are likely to cause further inequities in recovery and will require a response of health, education, employment, justice and political systems.

RESUMEN

There is evidence of Indigenous and ethnic minority inequities in the incidence and outcomes of early psychosis. racism has an important role. This study aimed to use Indigenous experiences to develop a more detailed understanding of how racism operates to impact early psychosis. Critical Race Theory informed the methods used. Twenty-three Indigenous participants participated in 4 family focus group interviews and 13 individual interviews, comprising of 9 youth, 10 family members and 4 mental health professionals. An analysis of the data was undertaken using deductive structural coding to identify descriptions of racism, followed by inductive descriptive and pattern coding. Participant experiences revealed how racism operates as a socio-cultural phenomenon that interacts with institutional policy and culture across systems. This is described across three themes: (1) selective responses based on racial stereotypes, (2) race related risk assessment bias and (3) institutional racism in the mental health workforce. The impacts of racism were reported as inaction in the face of social need, increased coercion and an under resourced Indigenous workforce. These findings indicate that organizational cultures may differentially impact Indigenous and minority people and that social responsiveness, risk discourse and the distribution of workforce expenditure are important targets for anti-racism efforts.

RESUMEN

BACKGROUND: Cognitive impairments are an emerging treatment target in mood disorders, but currently there are no evidence-based pro-cognitive treatments indicated for patients in remission. With this systematic review of randomised controlled trials (RCTs), the International Society for Bipolar Disorders (ISBD) Targeting Cognition Task force provides an update of the most promising treatments and methodological recommendations. METHODS: The review included RCTs of candidate pro-cognitive interventions in fully or partially remitted patients with major depressive disorder or bipolar disorder. We followed the procedures of the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) 2020 statement. Searches were conducted on PubMed/MEDLINE, PsycInfo, EMBASE and Cochrane Library from January 2015, when two prior systematic reviews were conducted, until February 2021. Two independent authors reviewed the studies with the Revised Cochrane Collaboration's Risk of Bias tool for Randomised trials. RESULTS: We identified 16 RCTs (N = 859) investigating cognitive remediation (CR; k = 6; N = 311), direct current or repetitive magnetic stimulation (k = 3; N = 127), or pharmacological interventions (k = 7; N = 421). CR showed most consistent cognitive benefits, with two trials showing improvements on primary outcomes. Neuromodulatory interventions revealed no clear efficacy. Among pharmacological interventions, modafinil and lurasidone showed early positive results. Sources of bias included small samples, lack of pre-screening for objective cognitive impairment, no primary outcome and no information on allocation sequence masking. CONCLUSIONS: Evidence for pro-cognitive treatments in mood disorders is emerging. Recommendations are to increase sample sizes, pre-screen for impairment in targeted domain(s), select one primary outcome, aid transfer to real-world functioning, investigate multimodal interventions and include neuroimaging.

RESUMEN

BACKGROUND: Developing treatments for cognitive impairment is key to improving the functioning of people with mood disorders. Neuroimaging may assist in identifying brain-based efficacy markers. This systematic review and position paper by the International Society for Bipolar Disorders Targeting Cognition Task Force examines the evidence from neuroimaging studies of pro-cognitive interventions. METHODS: We included magnetic resonance imaging (MRI) studies of candidate interventions in people with mood disorders or healthy individuals, following the procedures of the Preferred Reporting Items for Systematic reviews and Meta-Analysis 2020 statement. Searches were conducted on PubMed/MEDLINE, PsycInfo, EMBASE, Cochrane Library, and Clinicaltrials.gov from inception to 30th April 2021. Two independent authors reviewed the studies using the National Heart, Lung, Blood Institutes of Health Quality Assessment Tool for Controlled Intervention Studies and the quality of neuroimaging methodology assessment checklist. RESULTS: We identified 26 studies (N = 702). Six investigated cognitive remediation or pharmacological treatments in mood disorders (N = 190). In healthy individuals, 14 studies investigated pharmacological interventions (N = 319), 2 cognitive training (N = 73) and 4 neuromodulatory treatments (N = 120). Methodologies were mostly rated as 'fair'. 77% of studies investigated effects with task-based fMRI. Findings varied but most consistently involved treatment-associated cognitive control network (CCN) activity increases with cognitive improvements, or CCN activity decreases with no cognitive change, and increased functional connectivity. In mood disorders, treatment-related default mode network suppression occurred. CONCLUSIONS: Modulation of CCN and DMN activity is a putative efficacy biomarker. Methodological recommendations are to pre-declare intended analyses and use task-based fMRI, paradigms probing the CCN, longitudinal assessments, mock scanning, and out-of-scanner tests.

RESUMEN

OBJECTIVE: To examine the impact of a treatment package combining Interpersonal and Social Rhythm Therapy (IPSRT) and cognitive remediation (CR), vs IPSRT alone, on cognition, functioning, and mood disturbance outcomes in mood disorders. METHODS: A pragmatic randomised controlled trial in adults with bipolar disorder (BD) or major depressive disorder (MDD), recently discharged from mental health services in Christchurch, New Zealand, with subjective cognitive difficulties. Individuals were randomised to a 12-month course of IPSRT with CR (IPSRT-CR), or without CR (IPSRT). In IPSRT-CR, CR was incorporated into therapy sessions from approximately session 5 and continued for 12 sessions. The primary outcome was change in Global Cognition (baseline to 12 months). RESULTS: Sixty-eight individuals (BD n = 26, MDD n = 42; full/partial remission n = 39) were randomised to receive IPSRT-CR or IPSRT (both n = 34). Across treatment arms, individuals received an average of 23 IPSRT sessions. Change in Global Cognition did not differ between arms from baseline to treatment-end (12 months). Psychosocial functioning and longitudinal depression symptoms improved significantly more in the IPSRT compared with IPSRT-CR arm over 12 months, and all measures of functioning and mood symptoms showed moderate effect size differences favouring IPSRT (0.41-0.60). At 18 months, small to moderate, non-significant benefits (0.26-0.47) of IPSRT vs IPSRT-CR were found on functioning and mood outcomes. CONCLUSIONS: Combining two psychological therapies to target symptomatic and cognitive/functional recovery may reduce the effect of IPSRT, which has implications for treatment planning in clinical practice and for CR trials in mood disorders.

RESUMEN

BACKGROUND: Individuals with mood disorders frequently experience cognitive impairment, which impacts on the long-term trajectory of the disorders, including being associated with persisting difficulties in occupational and psychosocial functioning, residual mood symptoms, and relapse. Current first-line treatments for mood disorders do little to improve cognitive function. Targeting cognition in clinical research is thus considered a priority. This protocol outlines a prospectively-registered randomised controlled trial (RCT) which examines the impact of adding group-based Cognitive Remediation (CR) to Interpersonal and Social Rhythm Therapy (IPSRT-CR) for individuals with mood disorders. METHODS: This is a pragmatic, two-arm, single-blinded RCT comparing IPSRT-CR with IPSRT alone for adults (n = 100) with mood disorders (Major Depressive Disorder or Bipolar Disorder) with subjective cognitive difficulties, on discharge from Specialist Mental Health Services in Christchurch, New Zealand. Both treatment arms will receive a 12-month course of individual IPSRT (full dose = 24 sessions). At 6 months, randomisation to receive, or not, an 8-week group-based CR programme (Action-based Cognitive Remediation - New Zealand) will occur. The primary outcome will be change in Global Cognition between 6 and 12 months (treatment-end) in IPSRT-CR versus IPSRT alone. Secondary outcomes will be change in cognitive, functional, and mood outcomes at 6, 12, 18, and 24 months from baseline and exploratory outcomes include change in quality of life, medication adherence, rumination, and inflammatory markers between treatment arms. Outcome analyses will use an intention-to-treat approach. Sub-group analyses will assess the impact of baseline features on CR treatment response. Participants' experiences of their mood disorder, including treatment, will be examined using qualitative analysis. DISCUSSION: This will be the first RCT to combine group-based CR with an evidence-based psychotherapy for adults with mood disorders. The trial may provide valuable information regarding how we can help promote long-term recovery from mood disorders. Many issues have been considered in developing this protocol, including: recruitment of the spectrum of mood disorders, screening for cognitive impairment, dose and timing of the CR intervention, choice of comparator treatment, and choice of outcome measures.

RESUMEN

OBJECTIVES: Societal restrictions imposed to prevent transmission of COVID-19 may challenge circadian-driven lifestyle behaviours, particularly amongst those vulnerable to mood disorders. The overarching aim of the present study was to investigate the hypothesis that, in the routine-disrupted environment of the COVID-19, amongst a sample of people living with mood disorders, greater social rhythm disruption would be associated with more severe mood symptoms. METHODS: We conducted a two-wave, multinational survey of 997 participants (MAge=39.75±13.39,Female=81.6%) who self-reported a mood disorder diagnosis (i.e., major depressive disorder or bipolar disorder). Respondents completed questionnaires assessing demographics, social rhythmicity (The Brief Social Rhythm Scale), depression symptoms (Patient Health Questionnaire-9), sleep quality and diurnal preference (The Sleep, Circadian Rhythms and Mood questionnaire) and stressful life events during the COVID-19 pandemic (The Social Readjustment Rating Scale). RESULTS: The majority of participants indicated COVID-19-related social disruption had affected the regularity of their daily routines to at least some extent (n = 788, 79.1%). As hypothesised, lower social rhythmicity was associated with greater depressive symptoms when tested cross-sectionally (standardised ß = -.25, t = -7.94, P = 0.000) and when tested using a 2-level hierarchical linear model across two time points (b = -0.14, t = -3.46, df = 264, P ≤ 0.001). CONCLUSIONS: These results are consistent with the social zeitgeber hypothesis proposing that mood disorders are sensitive to life events that disrupt social rhythms.

RESUMEN

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with increased risk of many mental health conditions, including mood and anxiety disorders. Whether PCOS is more common in mental health conditions than in the general population is less clear. A systematic review investigating this question may provide clarity regarding whether increased prevalence of PCOS is seen in particular mental health disorders, and thus, whether screening female mental health patients for PCOS is warranted. AIMS: To systematically synthesise and review research examining rates of PCOS in mental health disorders. METHODS: Peer-reviewed articles assessing the prevalence of PCOS within a sample of reproductive-aged females with a diagnosis of Axis I or II mental health disorder were included. Key studies were identified through a comprehensive search of PubMed and Web of Science. RESULTS: Eleven studies met inclusion criteria, assessing rate of diagnosed PCOS in samples with bipolar disorder (n = 7), autism spectrum disorders (ASD; n = 2), bulimia nervosa (n = 1), and post-traumatic stress disorder (PTSD; n = 1). Overall, there was limited evidence of elevated rates of PCOS in bipolar disorder, compared with population estimates or healthy control group rates. In ASD, bulimia nervosa, and PTSD samples, significantly increased rates of PCOS were reported compared with healthy control samples, although studies were relatively small. CONCLUSIONS: This review highlights complexities and methodological considerations in this area of research. There are a limited number of studies assessing PCOS in mental health samples, and thus, important areas of future research have been identified. TRIAL REGISTRATION: This systematic review was registered on PROSPERO (ID: CRD42020151420; https://www.crd.york.ac.uk/prospero/ ) on 28 April 2020.

RESUMEN

Evidence suggests impairment in aspects of cognitive function in women with polycystic ovary syndrome (PCOS). Direct effects of raised testosterone levels associated with PCOS are a potential mechanism. We aimed to explore the relationship between testosterone levels and cognitive functioning in women. Women with a range of testosterone levels, including women with PCOS, were recruited. Depressive and anxiety symptoms were measured by self-report. Participants underwent a comprehensive battery of cognitive tests assessing psychomotor speed, visuospatial learning and memory, verbal learning and memory, and executive function. Free testosterone serum levels were assessed. All measures were completed at the same time point. Correlation analysis (Spearman's Rho) was used to explore associations between free testosterone and cognitive test variables. Eighty-one women were recruited, with 40 meeting diagnostic criteria for PCOS. Free testosterone was normally distributed, with significant overlap between women with PCOS and controls. Mean depressive and anxiety symptoms were in the mild range. Higher free testosterone levels were significantly correlated with poorer performance on measures assessing psychomotor speed and visuospatial learning. These significant correlations remained after adjusting for confounders (premorbid verbal IQ, depressive, and anxiety symptoms). Higher free testosterone levels in women were associated with poorer cognitive function, specifically psychomotor speed and visuospatial learning. Women with PCOS and raised free testosterone levels may experience impairment in these aspects of cognitive function which are not accounted for by mood or anxiety symptoms.

RESUMEN

OBJECTIVE: To examine the two-year outcomes for depression, anxiety, cognitive and global social functioning after cognitive behavioural therapy (CBT) and metacognitive therapy (MCT) for depression. METHOD: Participants were 31 adults with a diagnosis of major depressive disorder in a randomised pilot study comparing MCT and CBT. Therapy modality differences in change in depression and anxiety symptoms, dysfunctional attitudes, metacognitions, rumination, worry and global social functioning were examined at the two-year follow-up for those who completed therapy. RESULTS: Significant improvements, with large effect sizes, were evident for all outcome variables. There were no significant differences in outcome between CBT and MCT. The greatest change over time occurred for depression and anxiety. Large changes were evident for metacognitions, rumination, dysfunctional attitudes, worry and global social functioning. Sixty-seven percent had not experienced a major depression and had been well during all of the past year, prior to the follow-up assessment. CONCLUSION: The finding at end treatment, of no modality specific differences, was also evident at two-year follow-up. Although CBT and MCT targeted depression, improvements were much wider, and although CBT and MCT take different approaches, both therapies produced positive change over time across all cognitive variables. CBT and MCT provide treatment options, that not only improve the longer-term outcome of depression, but also result in improvements in anxiety, global social functioning and cognitive status.

RESUMEN

OBJECTIVES: This review aim was to examine whether psychotherapy is more or less effective in patients with SUD, compared to those without; whether there is a differential effect of a particular psychotherapy in patients with SUD. METHODS: A quantitative systematic review following the Cochrane Handbook of Systematic Reviews was used. RESULTS: Five studies of psychotherapy for BD and two studies of an integrated psychotherapy for comorbid BD and SUD were included in the review. Five studies provided a sub-analysis of the effect of SUD on overall outcomes with only one finding an overall detrimental effect. The results indicated equal, if not better outcomes for individuals with comorbid BD and SUD. CONCLUSION: There was little evidence that interventions targeted at both BD and SUD may be more efficacious. Further research in to psychotherapeutic treatment for BD should include individuals with comorbid SUD, and analyse substance use as an outcome. Additionally, research into treatments specifically developed for these commonly comorbid disorders is indicated.

RESUMEN

BACKGROUND: An automated web-based assessment and monitoring system ( www.psynary.com ) has been developed to assist non-specialist clinicians in managing common mood and anxiety disorders. Psynary promotes the use of standardised outcome measures to assess symptom severity and optimise treatments with the aim of improving outcomes and enabling faster recovery. This paper analyses the results from two parallel studies in New Zealand and Japan (OptiMA-1 NZ and Japan) to assess the validity of the R8 Depression scale, one of the system's core outcome measures. METHODS: Clinical samples were recruited from a public secondary care and a private psychiatry clinic. Participants completed the outcome measures for the study via the online Psynary system. The R8 Depression scale is a 30-item questionnaire which includes all symptom domains covered in the ICD-10 classification of depression. The Patient Health Questionnaire (PHQ-9) was completed at the same time points as the R8 Depression, with a smaller sample also completing a paper-based Quick Inventory of Depressive Symptomatology (QIDS-SR16). Internal validity was quantified via Cronbach's alpha and Guttman lower bounds method. External validation against the PHQ-9 and QIDS used the Pearson's and Kendall's correlation coefficients. Severity categories were set using a multivariate regression model. RESULTS: 270 patients participated in the study and completed a maximum of 1 baseline and 5 reviews within a 90-day period, giving a total of 1124 assessments with the PHQ-9 also being completed in 1053 of these assessments. R8 Depression normative data was also collected from 204 non-clinical volunteers with 187 of these also completing the PHQ9. Internal reliability scores were all higher than 0.9 (n = 1328). There was overall good external validity when comparing the R8 Depression to the PHQ-9, with a correlation of 0.91 for the combined normative and clinical samples (n = 1240). CONCLUSIONS: The R8 Depression has been developed as a patient-rated outcome measure for depression for administration on an online system called "Psynary". It has high internal and external validity against current widely used scales. Further work is underway to determine the sensitivity to change of the R8 Depression.

RESUMEN

OBJECTIVE: Neurocognitive impairment is considered a core feature of mood disorders. Research has shown that neurocognitive impairment often persists beyond mood symptom resolution and can have significant deleterious effects on interpersonal relationships, academic achievement, occupational functioning and independent living. As such, neurocognitive impairment has become an important target for intervention. In this systematic review, we aimed to examine the extant literature to ascertain whether current standard evidence-based psychotherapies can improve neurocognitive functioning in mood disorders. METHOD: Studies examining changes in neurocognitive functioning following evidence-based psychotherapy were identified using MEDLINE, PsycINFO and Web of Science databases. Given the heterogeneity of study procedures, treatment protocols and patient samples, a narrative rather than meta-analytic review technique was employed. RESULTS: Nineteen studies (21 articles) met inclusion criteria. There was preliminary evidence of improved executive functioning following evidence-based psychotherapy for Major Depressive Disorder and Bipolar Disorder. There was also some signal of reduced negative biases in emotional information processing following psychotherapy in depression. Due to methodological variability across studies however, it was difficult to draw clear conclusions. CONCLUSION: Findings from the current review suggest that evidence-based psychotherapies may influence some aspects of neurocognitive functioning in mood disorders. This continues to be an ongoing area of importance and warrants further research.

RESUMEN

This article is a detailed response to the criticisms levelled by the authors of an accompanying viewpoint, which claims that the positioning of repetitive transcranial magnetic stimulation (rTMS) in the 2020 Royal Australian and New Zealand College of Psychiatrists (RANZCP) clinical practice guidelines for the management mood disorders (MDcpg2020) is incorrect. We, the authors of the MDcpg2020, strongly refute these assertions and argue that first we have determined the positioning of rTMS using the same criteria as those applied to other treatments for depression. Second, in accordance with National Health and Medical Research Council (NHMRC) guidelines, the processes by which we have developed the MDcpg2020 have been guided by best practice and have been overseen throughout by the RANZCP. Third, our objective and detailed examination of the relevant research has shown that the evidence needed to support the positioning of rTMS alongside standard therapies for depression is severely deficient. And therefore, as a consequence, we set out clearly both our logic and reasoning with respect to interpreting rTMS data and outline our evidence-informed position in which rTMS remains a potential alternative therapy that can be considered in certain clinical circumstances once both suitable psychological and pharmacological treatments have been trialled. We also discuss why, until further research is conducted, rTMS is perhaps best regarded as an experimental therapy and an investigational tool, and to assist in this regard, we propose a framework for consideration by those conducting rTMS studies in the future. Thus, based on current knowledge, we conclude that rTMS does not have a sufficient evidence base to warrant recognition as a standard therapy for depression alongside established treatments such as psychological interventions, pharmacotherapy, and electroconvulsive therapy. Furthermore, there is no clinical profile for depressed patients that might benefit from rTMS and therefore tolerability alone is not good enough reason to promote rTMS in the management of major depression.

RESUMEN

OBJECTIVE: To examine the effects of 18 months of intensive stabilisation with medication management and Interpersonal and Social Rhythm Therapy or Non-specific Supportive Clinical Management on cognitive function in young people with bipolar disorder. Determinants of change in cognitive function over the 18 months of the trial were also examined. METHOD: Patients aged 15-36 years with Bipolar I Disorder, Bipolar II Disorder and Bipolar Not Otherwise Specified were recruited. From a battery of cognitive tests, change scores for pre-defined domains of cognitive function were created based on performance at baseline and follow-up. Change was compared between the two therapy groups. Regression analysis was used to determine the impact of a range of clinical variables on change in cognitive performance between baseline and follow-up. RESULTS: One hundred participants were randomised to Interpersonal and Social Rhythm Therapy (n = 49) or Non-specific Supportive Clinical Management (n = 51). Seventy-eight patients underwent cognitive testing at baseline and 18 months. Across both groups, there were significant improvements in a Global Cognitive Composite score, Executive Function and Psychomotor Speed domains from baseline to 18 months. Lower scores at baseline on all domains were associated with greater improvement over 18 months. Overall, there was no difference between therapies in change in cognitive function, either in a global composite score or change in domains. CONCLUSION: While there was no difference between therapy groups, intensive stabilisation with psychological therapy was associated with improved cognitive function, particularly in those patients with poorer cognitive function at baseline. However, this was not compared with treatment as usual so cannot be attributed necessarily to the therapies.

RESUMEN

OBJECTIVE: International guidelines suggest repeating cognitive testing at intervals throughout a course of electroconvulsive therapy (ECT) to monitor its effects on cognitive function. However, it is apparent that few services do this, and an optimal battery of testing has not yet been established. We aimed to evaluate the utility of such routine cognitive testing in a clinic where patients had been routinely tested at intervals throughout a course of ECT. METHODS: All patients referred for ECT at a public ECT clinic were offered routine cognitive testing to monitor cognitive function during their course of ECT. Testing was conducted at baseline and after 3, 6, and 9 treatments. Analyses examined whether change in individual measures predicted reduction in autobiographical memory at subsequent measures and whether the results that were given to clinicians informed treatment decisions. RESULTS: Changes in cognitive test results were not associated with clinician decisions to change treatment parameters. Only change in digit span forwards after 3 treatments was associated with later reduction in Colombia University Autobiographical Interview - Short Form (CUAMI-SF) of greater than 25%, with a larger improvement in digit span forwards being associated with greater chance of having a 25% reduction in CUAMI-SF. CONCLUSIONS: There was no evidence that the screening undertaken in this clinic had been helpful in determining treatment decisions or that changes in cognitive tests predicted in a reliable way who would later experience changes in autobiographical memory. However, follow-up testing was not completed reliably, and longer-term data regarding autobiographical memory were not collected.

RESUMEN

BACKGROUND: Impairments in affective cognition are part of the neurocognitive profile and possible treatment targets in bipolar disorder (BD), but the findings are heterogeneous. The International Society of Bipolar Disorder (ISBD) Targeting Cognition Task Force conducted a systematic review to (i) identify the most consistent findings in affective cognition in BD, and (ii) provide suggestions for affective cognitive domains for future study and meta-analyses. METHODS: The review included original studies reporting behavioral measures of affective cognition in BD patients vs controls following the procedures of the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) statement. Searches were conducted on PubMed/MEDLINE, EMBASE, and PsychInfo from inception until November 2018. RESULTS: A total of 106 articles were included (of which nine included data for several affective domains); 41 studies assessed emotional face processing; 23 studies investigated reactivity to emotional words and images; 3 investigated explicit emotion regulation; 17 assessed implicit emotion regulation; 31 assessed reward processing and affective decision making. In general, findings were inconsistent. The most consistent findings were trait-related difficulties in facial emotion recognition and implicit emotion regulation, and impairments in reward processing and affective decision making during mood episodes. Studies using eye-tracking and facial emotion analysis revealed subtle trait-related abnormalities in emotional reactivity. CONCLUSION: The ISBD Task Force recommends facial expression recognition, implicit emotion regulation, and reward processing as domains for future research and meta-analyses. An important step to aid comparability between studies in the field would be to reach consensus on an affective cognition test battery for BD.

RESUMEN

BACKGROUND: Inpatients with depression have a poor long term outcome with high rates of suicide, high levels of morbidity and frequent re-admission. Current treatment often relies on pharmacological intervention and focuses on observation to maintain safety. There is significant neurocognitive deficit which is linked to poor functional outcomes. As a consequence, there is a need for novel psychotherapeutic interventions that seek to address these concerns. METHODS: We combined cognitive activation and behavioural activation to create activation therapy (AT) for the treatment of inpatient depression and conducted a small open label study which demonstrated acceptability and feasibility. We propose a randomised controlled trial which will compare treatment as usual (TAU) with TAU plus activation therapy for adult inpatients with a major depressive episode. The behavioural activation component involves therapist guided re-engagement with previously or potentially rewarding activities. The cognitive activation aspect utilises computer based exercises which have been shown to improve cognitive function. DISCUSSION: The proposed randomised controlled trial will examine whether or not the addition of this therapy to TAU will result in a reduced re-hospitalisation rate at 12 weeks post discharge. Subjective change in activation and objectively measured change in activity levels will be rated, and the extent of change to neurocognition will be assessed. TRIAL REGISTRATION: Unique trial number: U1111-1190-9517. Australian New Zealand Clinical Trials Registry (ANZCTR) number: ACTRN12617000024347p .
