RESUMO

The Functional Assessment Short Test (FAST) is a clinician-administered assessment scale of psychosocial dysfunction across various domains typically impacted in individuals with bipolar disorder. The FAST is formally validated as a clinician-administered measure, but support for self-administration would allow its wider use. Therefore, this study aimed to determine whether the FAST could reliably serve as a self-report measure in individuals seeking mental health treatment. Participants completed both the self-report and clinician-administered versions of the FAST as part of their routine outpatient clinical care at the Bipolar Disorders Clinic at The University of Texas Health Austin (UTHA). We investigated correlations between self-report and clinician-administered FAST scores. There were significant positive correlations between self-report and clinician-administered scores in a diverse group of 84 individuals undergoing outpatient mental health treatment (Total FAST scores rS = 0.75; p < .001). These findings support using the FAST as a self-report scale, further increasing its utility to measure functional disability in mental health conditions such as bipolar disorder. Self-report application will increase the utility of the FAST in busy clinical workflows and, therefore, contribute to a more comprehensive clinical assessment of recovery and spur interventions that improve psychosocial functioning and quality of life.

RESUMO

BACKGROUND: The use of alcohol and nicotine can negatively impact the course of bipolar disorder (BD), but there is limited knowledge about how symptoms and sleep disturbances are related to concurrent nicotine use and non-pathological use of alcohol. METHODS: We investigated how nicotine use and non-pathological use of alcohol relates to affective symptoms and sleep disturbances in 453 participants with BD without substance use disorders. Manic symptoms were assessed with the Young Mania Rating Scale, and depressive symptoms with The Inventory of Depressive Symptomatology, Clinician-Rated (IDS-C). Sleep-related questions from IDS-C were used to create proxy variables for sleep disturbances, including Insomnia and Hypersomnia. Multinomial regression analysis was conducted to investigate the associations between nicotine use and sleep disturbances, controlling for possible confounders such as current use of illicit drugs and psychopharmacological treatment. RESULTS: Depressive and manic symptoms were not associated with the concurrent level of alcohol or nicotine use. Individuals with medium and high levels of daily nicotine use had higher risk of insomnia than those without. Non-pathological alcohol use was not associated with sleep disturbances. LIMITATIONS: Sleep disturbances were based on items from the IDS-C questionnaire. CONCLUSION: We found an elevated risk for insomnia in individuals with BD and medium or high levels of daily nicotine use. We found no association between the level of affective symptoms and the level of use of alcohol or nicotine. The direction of the relationship between nicotine use and insomnia needs clarification, as it is highly relevant for treatment planning.

RESUMO

Objective: A systematic review was conducted to examine resilience in bipolar disorder (BD) and its relationship to demographic, psychopathology, illness features, and psychosocial functioning.Data Sources: A literature search was conducted from database inception to August 2022 using PubMed, Web of Science, EMBASE, and PsycINFO. Reference lists were also manually searched for relevant articles.Study Selection: Studies were included if they involved patients with a primary diagnosis of BD, were published in English, and measured resilience using a clearly defined rating scale. Studies were excluded if they were case reports, systematic reviews, or conference articles. Of the initial 100 records screened after duplicates were removed, 29 articles were finally included in the systematic review.Data Extraction: Information extracted included the number and type of subjects, socio-demographic characteristics, resilience scale(s) used, and relevant clinical correlates.Results: Higher resilience in BD was associated with specific psychopathology (lower severity of depressive and psychotic symptoms; less rumination, hopelessness, impulsivity, and aggression; fewer depressive episodes and suicide attempts), clinical features (self-directed temperament, less childhood trauma, and positive attitudes toward pharmacologic treatment), social factors (better social support and family organization), and psychosocial functioning (better quality of life, social functioning, personal recovery, and spiritual well-being). Resilience also mediated pathways between childhood trauma, depression, and quality of life.Conclusions: Based on resilience models, BD patients can be helped to better manage challenges and stressors and bolster internal compensatory factors and external protective factors during the course of their illness.

RESUMO

BACKGROUND: Molecular biomarkers for bipolar disorder (BD) that distinguish it from other manifestations of depressive symptoms remain unknown. The aim of this study was to determine if a very sensitive tyramine-based signal-amplification technology for flow cytometry (CellPrint™) could facilitate the identification of cell-specific analyte expression profiles of peripheral blood cells for bipolar depression (BPD) versus healthy controls (HCs). METHODS: The diagnosis of psychiatric disorders was ascertained with Mini International Neuropsychiatric Interview for DSM-5. Expression levels for eighteen protein analytes previously shown to be related to bipolar disorder were assessed with CellPrint™ in CD4+ T cells and monocytes of bipolar patients and HCs. Implementation of protein-protein interaction (PPI) network and pathway analysis was subsequently used to identify new analytes and pathways for subsequent interrogations. RESULTS: Fourteen drug-naïve or -free patients with bipolar I or II depression and 17 healthy controls (HCs) were enrolled. The most distinguishable changes in analyte expression based on t-tests included GSK3ß, HMGB1, IRS2, phospho-GSK3αß, phospho-RELA, and TSPO in CD4+ T cells and calmodulin, GSK3ß, IRS2, and phospho-HS1 in monocytes. Subsequent PPI and pathway analysis indicated that prolactin, leptin, BDNF, and interleukin-3 signal pathways were significantly different between bipolar patients and HCs. LIMITATION: The sample size of the study was small and 2 patients were on medications. CONCLUSION: In this pilot study, CellPrint™ was able to detect differences in cell-specific protein levels between BPD patients and HCs. A subsequent study including samples from patients with BPD, major depressive disorder, and HCs is warranted.

RESUMO

BACKGROUND: Women with bipolar disorder have approximately 40 %-50 % chance of having a perinatal bipolar recurrence. Knowing the factors associated will be beneficial for the prediction and prevention of episodes. We aim to establish if borderline personality disorder traits, as measured by the BEST (Borderline Evaluation of Severity over Time) scale, are associated with perinatal psychiatric outcomes. METHODS: We recruited women with bipolar disorder as part of the BDRN (Bipolar Disorder Research Network) study. Women were interviewed and we collected their demographic and clinical information. Participants subsequently completed the BEST questionnaire. We analysed the association of BEST scores with lifetime presence/absence of perinatal bipolar relapse and, employing multinomial logistic regression, with different subtypes of perinatal outcomes: postpartum psychosis; postpartum depression, and other episodes. RESULTS: In our sample of 807, although there was no significant association between the BEST total score and perinatal episodes as a whole (adjustedOR 1.01 CI95% [0.99, 1.03], p = 0.204), we found significant differing associations with different subtypes of episodes. Women scoring highly on BEST were less likely to experience a postpartum psychotic episode (RRR 0.96 CI95% [0.94, 0.99], p = 0.005) but more likely to experience a non-psychotic depressive episode (RRR 1.03 CI95% [1.01, 1.05], p = 0.007) than no relapse. LIMITATIONS: This study is limited by its cross-sectional design and self-report nature of BEST. CONCLUSIONS: In women with bipolar disorder, borderline traits differentiate the risk of postpartum depression and postpartum psychosis, emphasise the importance of considering risk factors for these perinatal episodes separately, and may help individualise the risk for women in the perinatal period.

RESUMO

Bipolar disorder is associated with suicidal behavior. The risk of suicide for individuals with bipolar disorder is up to 20-30 times larger than that of the general population. Considerable evidence suggests that testosterone may play a role in the pathophysiology of suicidal behavior in both men and women with bipolar disorder and other psychiatric conditions. Testosterone has complex effects on psychological traits. It affects mood and behavior, including interactions with other people. Testosterone regulates pro-active and re-active aspects of aggression. Probably, both high and low levels of testosterone may contribute to the neurobiology of suicide in various patient populations. The effects of endogenous and exogenous testosterone on suicidality in patients with bipolar disorder need further investigation. The aim of this commentary article is to provide a commentary on the author's work on the topic, summarize the literature on testosterone, bipolar disorder, and suicide, and encourage future research on this poorly studied topic.

RESUMO

Adults with severe mental ill health may have specific attitudes toward physical activity. To inform intervention development, we conducted a survey to assess the physical activity patterns, preferences, barriers, and motivations of adults with severe mental ill health living in the community. Data were summarised using descriptive statistics, and logistic regressions were used to explore relationships between physical activity status and participant characteristics. Five-hundred and twenty-nine participants (58% male, mean age 49.3 years) completed the survey. Large numbers were insufficiently active and excessively sedentary. Self-reported levels of physical activity below that recommended in national guidelines were associated with professional inactivity, consumption of fewer than five portions of fruit and vegetables per day, older age, and poor mental health. Participants indicated a preference for low-intensity activities and physical activity that they can do on their own, at their own time and pace, and close to home. The most commonly endorsed source of support was social support from family and friends. Common motivations included improving mental health, physical fitness, and energy levels. However, poor mental and physical health and being too tired were also common barriers. These findings can inform the development of physical activity interventions for this group of people.

RESUMO

In bipolar disorder, dysregulation of affect is a core feature while knowledge on affective lability in schizophrenia is sparse. Research on affective lability in partners to individuals with schizophrenia or bipolar disorder is also lacking. The objective of this study was to investigate affective lability in parents with schizophrenia or bipolar disorder, and their co-parents without these disorders. The Danish High Risk and Resilience Study - VIA 7 is a population-based cohort study. This study focuses on parents diagnosed with schizophrenia (n = 148), their co-parents (n = 157), parents with bipolar disorder (n = 98), their co-parents (n = 89) and control parents (n = 359). The Affective Lability Scale - short form (ALS-SF) was used to measure affective lability. We found significantly higher levels of affective lability in parents with schizophrenia and bipolar disorder compared with controls, but no significant differences between bipolar disorder and schizophrenia. Co-parents to parents with schizophrenia had significantly higher levels of affective lability compared to controls. Our results add to the existing knowledge concerning underlying transdiagnostic factors and nonrandom mating in schizophrenia and bipolar disorder and highlight the need for studies of parental affective lability as a potential risk factor for offspring in families with parental schizophrenia or bipolar disorder.

RESUMO

Childhood maltreatment is associated with the etiology and clinical course of bipolar disorder. Most studies employ retrospective maltreatment self-reports which are vulnerable to bias, raising questions about their validity and reliability. This study examined the test-retest reliability over 10 years, the convergent validity and the impact of current mood on retrospective reports of childhood maltreatment in a bipolar sample. 85 participants with bipolar I disorder completed the Childhood Trauma Questionnaire [CTQ] and the Parental Bonding Instrument [PBI] at baseline. Beck Depression Inventory and Self Report Mania Inventory assessed depressive and manic symptoms, respectively. 53 participants completed the CTQ at baseline and 10-year follow-up. Good levels of convergent validity were observed between the CTQ and PBI. Correlations ranged from rs= -0.35 (CTQ emotional abuse and PBI paternal care) to rs= -0.65 (CTQ emotional neglect and PBI maternal care). Good agreement between CTQ reports at baseline and 10-year follow-up were found (range: κ=0.41 for physical neglect to κ=0.83 for sexual abuse). Higher depression and mania scores were recorded among participants who reported abuse (but not neglect) compared to those without such reports. These findings support using this method in research and clinical practice, though current mood should be taken into account.

RESUMO

BACKGROUND: Although psychotherapy is an important pillar in the treatment of bipolar disorders, alongside pharmacotherapy, non-drug and complementary procedures, there is no up to date evidence synthesis for inpatient psychotherapeutic treatment and work with caregivers. OBJECTIVE: To review and evaluate the current study situation on evidence-based inpatient psychotherapy for bipolar disorders. MATERIAL AND METHODS: 1.Summary of the evidence for inpatient psychotherapy in adolescents and adults with bipolar disorders from current review articles and guidelines (German S3 guidelines, Australian, Canadian, and British NICE guidelines). 2. Systematic literature search (PRISMA) in Cochrane trials and Medline (via PubMed). 2a. Identification of original articles using the following search term: "bipolar fft" OR "bipolar ipsrt" OR "bipolar cbt" OR "bipolar cognitive remediation" OR "bipolar psychotherapy inpatient". 2b. Screening of n = 942 publications on the following inclusion criteria: randomized controlled efficacy trials, inpatient treatment/recruitment in the inpatient setting, adolescent or adult patients with bipolar disorder or caregivers. RESULTS: The guidelines recommend a combination of pharmacotherapy and psychotherapy for the treatment of patients with bipolar disorders (so far no evidence-based presentation of inpatient psychotherapy). The results from reviews and original papers are heterogeneous. Recently described evidence-based psychotherapeutic approaches for inpatient treatment are family focused therapy (FFT), interpersonal and social rhythm therapy (IPSRT) and psychoeducation. CONCLUSION: Although the current evidence is heterogeneous and further systematic studies are necessary, the results indicate that psychotherapy should be started or initiated in the inpatient setting with inclusion of caregivers.

RESUMO

BACKGROUND: Cognitive impairment is one of the major symptoms of individuals with bipolar disorder (BD). Purine system disorders may play an important role in cognitive dysfunction. So far, the relationship between cognitive deficits and purinergic metabolism in BD has been seldom discussed in previous studies. This study aims to explore its relevance and potential biological mechanisms. METHODS: In this cross-sectional study, 205 first time diagnosed drug-naive individuals with BD and 97 healthy volunteers were recruited. The uric acid(UA) level was measured using automatic biochemical analyzer, and cognitive function was assessed by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Stroop color-word test. In addition, general information and clinical symptoms were collected and evaluated. RESULTS: In this study, the UA level of BD group (U = 8475.000, p = 0.038) was found to be significantly higher than that of the healthy controls, but the scores of RBANS (t = -11.302, p < 0.001) and Stroop color-word test (t = -6.962, p < 0.001) were significantly lower than that of the healthy controls. In gender subgroup analysis, females had lower UA level and higher RBANS scores. In correlation analysis, the cognitive function of individuals with BD was found to present a significant negative correlation with UA level in attention (r = -0.23, p = 0.001) and delayed memory(r = -0.16, p = 0.022). LIMITATIONS: This is a cross-sectional design. CONCLUSION: Elevated UA levels may be a potential mechanism of cognitive impairment in BD. This provides a new possible strategy for the prevention and treatment of cognitive impairment in BD.

RESUMO

BACKGROUND: Bipolar disorder is a severe psychiatric syndrome defined by periodic mood shifts. Patients with bipolar disorder show cognitive impairments relative to healthy controls. The risk of developing schizophrenia, and partially also bipolar disorder, has previously been shown to increase with lower premorbid intelligence. It is not known if premorbid intelligence is associated with level of functioning and illness severity of people having developed bipolar disorder. METHODS: We used multiple linear and ordinal regression to analyze how premorbid intelligence, as measured at conscription, associate with functional outcome and illness severity in Swedish male bipolar disorder patients (n = 788). RESULTS: We found that lower premorbid intelligence is associated with lower percentage of time in work, after adjusting for age and bipolar subtype, and correcting for multiple comparisons. We also found a strong negative association with the total number of inpatient episodes and psychiatric comorbidity, but not with interepisodic remission, treatment with psychotherapy or lithium or the presence of any complicating socioeconomical factors. Adjusting for confounding genetic factors using polygenic risk scores for bipolar disorder and schizophrenia had no effect on the associations. LIMITATIONS: This study lacks females and controls and may thus have lower generalizability. CONCLUSION: In conclusion, premorbid intelligence is associated with both level of functioning and illness severity as well as comorbidity in bipolar disorder patients. Further research is needed to develop targeted interventions for this subgroup of bipolar disorder patients.

RESUMO

INTRODUCTION: Mood states have been reported to manifest a cross-sectional correlation with self-assessment accuracy across functional domains and psychiatric conditions. Ecological momentary assessment (EMA) provides a strategy to examine the momentary course and correlates of mood states. This study tested the association of moods assessed longitudinally with accuracy of immediate self-assessments of cognitive test performance in participants with schizophrenia and bipolar disorder. METHODS: 240 well-diagnosed participants with schizophrenia and bipolar disorder completed a subset of tests from the MATRICS Consensus Cognitive Battery and an immediate self-assessment of cognitive performance. Differences between actual and self-reported performance were used to index the accuracy of self-assessment. Daily smartphone EMA, 3× per day for 30 days, sampled participants´ momentary moods (sad, happy, relaxed, anxious), aggregated into positive affect and negative affect (NA). RESULTS: Bipolar participants had better cognitive performance, but both samples had equivalent mis-estimation. Repeated-measures analyses found that NA did not manifest significant variability over time either between or within participants in the two diagnostic groups. Within-group analyses found that higher average NA was associated with greater mis-estimation and poorer cognitive performance in participants with bipolar disorder, but not in those with schizophrenia. CONCLUSION: Negative moods had a significant association with impairments in self-assessment of cognitive performance in participants with bipolar disorder. Our study did not confirm previous cross-sectional findings of more accurate self-assessment associated with greater NA in schizophrenia. These findings suggest that cross-sectional assessments, particularly self-reports, may lead to different results than aggregated data from longitudinal evaluations.

RESUMO

Major depressive disorder (MDD), bipolar disorder (BD), and schizophrenia spectrum disorders (SZ) exhibit considerable phenotypic and genetic overlap. However, the contribution of genetic factors to their shared psychopathological symptom dimensions remains unclear. The present exploratory study investigated genetic contributions to the symptom dimensions "Depression", "Negative syndrome", "Positive formal thought disorder", "Paranoid-hallucinatory syndrome", and "Increased appetite" in a transdiagnostic subset of the German FOR2107 cohort (n = 1042 patients with MDD, BD, or SZ). As replication cohort, a subset of the German/Austrian PsyCourse study (n = 816 patients with MDD, BD, or SZ) was employed. First, the relationship between symptom dimensions and common variants associated with MDD, BD, and SZ was investigated via polygenic risk score (PRS) association analyses, with disorder-specific PRS as predictors and symptom dimensions as outcomes. In the FOR2107 study sample, PRS for BD and SZ were positively associated with "Positive formal thought disorder", the PRS for SZ was positively associated with "Paranoid-hallucinatory syndrome", and the PRS for BD was negatively associated with "Depression". The effects of PRS for SZ were replicated in PsyCourse. No significant associations were observed for the MDD PRS. Second, genome-wide association studies (GWAS) were performed for the five symptom dimensions. No genome-wide significant associations and no replicable suggestive associations (p < 1e-6 in the GWAS) were identified. In summary, our results suggest that, similar to diagnostic categories, transdiagnostic psychiatric symptom dimensions are attributable to polygenic contributions with small effect sizes. Further studies in larger thoroughly phenotyped psychiatric cohorts are required to elucidate the genetic factors that shape psychopathological symptom dimensions.

RESUMO

BACKGROUND: Higher levels of neurofilament light chain (NfL) and proinflammatory cytokines (i.e., tumor necrosis factor [TNF]-α) were observed in patients with bipolar disorder (BD) and major depressive disorder (MDD). Procollagen type 1 N-terminal propeptide (P1NP), a bone turnover biomarker, is related to MDD. The association among the brain-bone axis, systemic inflammation, and cognitive function remains unclear in severe affective disorders. METHODS: Overall, 25 patients with BD, 24 with MDD, and 29 matched controls were enrolled in the current study and underwent the measurements of the NfL, P1NP, and proinflammatory cytokine levels and 1-back and 2-back working memory tasks. Generalized linear models (GLMs) were used to examine the aforementioned biomarkers between the groups and clarify the association with each other. RESULTS: GLMs showed increased levels of NfL (p = 0.001, p = 0.020) and P1NP (p = 0.050, p = 0.032) in the patients with BD and MDD than in the controls and suggested significant correlations between the NfL level and the mean time of the 2-back working memory task (p = 0.038) and between P1NL and TNF-α levels (p < 0.001). DISCUSSION: Our study revealed the dysregulated brain-bone axis, indicated by elevated NfL and P1NP levels, and related cognitive impairment and systemic inflammation in the patients with BD and MDD. Additional studies are necessary to elucidate definite pathomechanisms underlying those conditions.

RESUMO

BACKGROUND: Cognitive reserve (CR) is closely associated with cognitive and functional outcome, disease severity, progression and prognosis in psychiatric patients; however, it has not been extensively tested in mood disorders. This study examined the psychometric properties of the Cognitive Reserve Assessment Scale in Health (CRASH) in mood disorder patients. METHODS: Altogether 166 subjects were recruited, 44 with major depressive disorder (MDD), 64 with bipolar disorder (BD), and 58 healthy controls. CR was assessed using the CRASH and the Cognitive Reserve Questionnaire (CRQ). RESULTS: Internal consistency (Cronbach's alpha) was 0.779 for the CRASH. The Receiver Operating Characteristic (ROC) curve analysis revealed an area under the ROC curve (AUC) value of 0.73 (95 % CI: 0.647-0.809). The optimal cut-off score of 51 generated the best combination of sensitivity (0.78) and specificity (0.43) for discriminating between patients with mood disorders and healthy controls. The CRASH score was highly correlated with the CRQ score in both mood disorder patients (rs = 0.586, P < 0.001) and healthy controls (rs = 0.627, P < 0.001), indicating acceptable convergent validity for the CRASH. Within the mood disorder sample, the CRASH score was associated with functional outcomes (FAST: rs = -0.243, P = 0.011). CONCLUSIONS: The CRASH is a useful tool to measure CR in mood disorder with acceptable psychometric properties and could be used in both research and clinical practice.

RESUMO

BACKGROUND: Bipolar disorder (BD) and alcohol use disorder (AUD) commonly co-occur and their interplay is influenced by several factors. Alexithymia is connected to BD and AUD; affective temperaments serve as risk factors for both; craving contributes to the development and maintenance of AUD. The present study tested whether alexithymia play a mediating role in the relationship between affective temperaments and craving in alcoholic bipolar patients. METHODS: 151 alcoholic bipolar patients (38 % females, mean age: 45.69 ± 9.04 years) were enrolled. The Mini International Neuropsychiatric Interview (MINI), the Brief Psychiatric Rating Scale (BPRS), the Toronto Alexithymia Scale (TAS-20), the Temperament Evaluation of the Memphis, Pisa, Paris and San Diego scale (TEMPS-A), and the Typology Craving Questionnaire (CTQ) were administered. Correlations among TAS-20, TEMPS-A, CTQ were conducted. Regression analyses were applied to verify the mediating hypothesis. RESULTS: Difficulty in identifying feelings mediated the association between anxious temperament and craving (Indirect effect: 0.42, BCaCI: 0.22-0.69), cyclothymic temperament and craving (Indirect effect: 0.55, BCaCI: 0.30-0.87), irritable temperament and craving (Indirect effect: 0.45, BCaCI: 0.19-0.80). TAS-20 difficulty in communicating feelings to others mediated the association between anxious temperament and craving (Indirect effect: 0.20, BCaCI: 0.06-0.41). LIMITATIONS: The sample size did not allow subgroup analyses. Data were collected cross-sectionally and in a single center. We did not investigate whether BD or AUD occurred first, although it might influence the mediation role of alexithymia. CONCLUSION: Among alcoholic bipolar patients, assessing and targeting alexithymia may be useful to modulate craving and, in turn improve, the general mental status of patients.

RESUMO

BACKGROUND: Depressive features and comorbid anxiety disorders are two discrete but interconnected clinical features that have been reported to be associated with a poorer quality of life (QoL) among individuals with bipolar disorders. However, the relationship between manic features and quality of life is less conclusive. The present study aimed to assess differences in QoL among bipolar outpatients who present with either depressive predominant polarity (DPP), manic predominant polarity (MPP) and/or a lifetime diagnosis of comorbid anxiety disorders in Singapore. METHODS: Data from 74 outpatients in Singapore diagnosed with bipolar disorder were collected. Sociodemographic information, the polarity of most episodes (2 out of 3), the diagnosis of anxiety disorders and QoL were obtained from a self-reported interview and/or through clinical records. QoL was measured using the abbreviated version of the World Health Organization questionnaire. We used multivariate regression models to determine the relationships between predominant polarity, lifetime comorbid anxiety disorders and QoL in physical health, psychological health, social relationships and environment domains. RESULTS: After adjusting for covariates, individuals with DPP scored poorer for WHOQOL-BREF for all four domains as compared with individuals with indeterminate polarity. As compared to individuals with indeterminate polarity, individuals with MPP scored poorer for WHOQOL-BREF social relationships. Lastly, individuals with lifetime comorbid anxiety disorders scored poorer for WHOQOL-BREF physical health, social relationships and environment. DISCUSSION AND CONCLUSIONS: The present study provides preliminary support for the relationship between DPP, lifetime comorbid anxiety disorders and poorer QoL, paving the pathway for future research with larger samples to utilise our study design to verify our results.
