RESUMO

BACKGROUND: Since insomnia and depression are interrelated, improved sleep early in antidepressant pharmacotherapy may predict a positive treatment outcome. We investigated whether early insomnia improvement (EII) predicted treatment outcome in psychotic depression (PD) and examined if there was an interaction effect between EII and treatment type to assess if findings were treatment-specific. METHODS: This study is a secondary analysis of a randomized trial comparing 7 weeks treatment with the antidepressants venlafaxine, imipramine and venlafaxine plus the antipsychotic quetiapine in PD ( n = 114). Early insomnia improvement, defined as ≥20% reduced insomnia after 2 weeks, was assessed by the Hamilton Rating Scale for Depression (HAM-D-17). Associations between EII and treatment outcome were examined using logistic regressions. Subsequently, we added interaction terms between EII and treatment type to assess interaction effects. The predictive value of EII was compared with early response on overall depression (≥20% reduced HAM-D-17 score after 2 weeks). RESULTS: EII was associated with response (odds ratio [OR], 7.9; 95% confidence interval [CI], 2.7-23.4; P = <0.001), remission of depression (OR, 6.1; 95% CI, 1.6-22.3; P = 0.009), and remission of psychosis (OR, 4.1; 95% CI, 1.6-10.9; P = 0.004). We found no interaction effects between EII and treatment type on depression outcome. Early insomnia improvement and early response on overall depression had a comparable predictive ability for treatment outcome. CONCLUSIONS: Early insomnia improvement was associated with a positive outcome in pharmacotherapy of PD, regardless of the medication type. Future studies are needed to confirm our findings and to examine the generalizability of EII as predictor in treatment of depression.

RESUMO

BACKGROUND: Evidence is limited regarding the most effective pharmacological treatment for psychotic depression: monotherapy with an antidepressant, monotherapy with an antipsychotic, another treatment (e.g. mifepristone), or combination of an antidepressant plus an antipsychotic. This is an update of a review first published in 2005 and last updated in 2015. OBJECTIVES: 1. To compare the clinical efficacy of pharmacological treatments for patients with an acute psychotic depression: antidepressant monotherapy, antipsychotic monotherapy, mifepristone monotherapy, and the combination of an antidepressant plus an antipsychotic versus placebo and/or each other. 2. To assess whether differences in response to treatment in the current episode are related to non-response to prior treatment. SEARCH METHODS: A search of the Cochrane Central Register of Controlled Trials (CENTRAL), in the Cochrane Library; the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR); Ovid MEDLINE (1950-); Embase (1974-); and PsycINFO (1960-) was conducted on 21 February 2020. Reference lists of all included studies and related reviews were screened and key study authors contacted. SELECTION CRITERIA: All randomised controlled trials (RCTs) that included participants with acute major depression with psychotic features, as well as RCTs consisting of participants with acute major depression with or without psychotic features, that reported separately on the subgroup of participants with psychotic features. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed risk of bias in the included studies, according to criteria from the Cochrane Handbook for Systematic Reviews of Interventions. Data were entered into RevMan 5.1. We used intention-to-treat data. Primary outcomes were clinical response for efficacy and overall dropout rate for harm/tolerance. Secondary outcome were remission of depression, change from baseline severity score, quality of life, and dropout rate due to adverse effects. For dichotomous efficacy outcomes (i.e. response and overall dropout), risk ratios (RRs) with 95% confidence intervals (CIs) were calculated.  Regarding the primary outcome of harm, only overall dropout rates were available for all studies. If the study did not report any of the response criteria as defined above, remission as defined here could be used as an alternative. For continuously distributed outcomes, it was not possible to extract data from the RCTs.  MAIN RESULTS: The search identified 3947 abstracts, but only 12 RCTs with a total of 929 participants could be included in the review. Because of clinical heterogeneity, few meta-analyses were possible. The main outcome was reduction in severity (response) of depression, not of psychosis. For depression response, we found no evidence of a difference between antidepressant and placebo (RR 8.40, 95% CI 0.50 to 142.27; participants = 27, studies = 1; very low-certainty evidence) or between antipsychotic and placebo (RR 1.13, 95% CI 0.74 to 1.73; participants = 201, studies = 2; very low-certainty evidence). Furthermore, we found no evidence of a difference in overall dropouts with antidepressant (RR 1.24, 95% CI 0.34 to 4.51; participants = 27, studies = 1; very low-certainty evidence) or antipsychotic monotherapy (RR 0.79, 95% CI 0.57 to 1.08; participants = 201, studies = 2; very low-certainty evidence). No evidence suggests a difference in depression response (RR 2.09, 95% CI 0.64 to 6.82; participants = 36, studies = 1; very low-certainty evidence) or overall dropouts (RR 1.79, 95% CI 0.18 to 18.02; participants = 36, studies = 1; very low-certainty evidence) between antidepressant and antipsychotic. For depression response, low- to very low-certainty evidence suggests that the combination of an antidepressant plus an antipsychotic may be more effective than antipsychotic monotherapy (RR 1.83, 95% CI 1.40 to 2.38; participants = 447, studies = 4), more effective than antidepressant monotherapy (RR 1.42, 95% CI 1.11 to 1.80; participants = 245, studies = 5), and more effective than placebo (RR 1.86, 95% CI 1.23 to 2.82; participants = 148, studies = 2). Very low-certainty evidence suggests no difference in overall dropouts between the combination of an antidepressant plus an antipsychotic versus antipsychotic monotherapy (RR 0.79, 95% CI 0.63 to 1.01; participants = 447, studies = 4), antidepressant monotherapy (RR 0.91, 95% CI 0.55 to 1.50; participants = 245, studies = 5), or placebo alone (RR 0.75, 95% CI 0.48 to 1.18; participants = 148, studies = 2). No study measured change in depression severity from baseline, quality of life, or dropouts due to adverse events. We found no RCTs with mifepristone that fulfilled our inclusion criteria. Risk of bias is considerable: we noted differences between studies with regards to diagnosis, uncertainties around randomisation and allocation concealment, treatment interventions (pharmacological differences between various antidepressants and antipsychotics), and outcome criteria. AUTHORS' CONCLUSIONS: Psychotic depression is heavily under-studied, limiting confidence in the conclusions drawn. Some evidence indicates that combination therapy with an antidepressant plus an antipsychotic is more effective than either treatment alone or placebo. Evidence is limited for treatment with an antidepressant alone or with an antipsychotic alone. Evidence for efficacy of mifepristone is lacking.

RESUMO

OBJECTIVE: To evaluate the development and implementation of clinical practice guidelines for the management of depression globally. METHODS: We conducted a systematic review of existing guidelines for the management of depression in adults with major depressive or bipolar disorder. For each identified guideline, we assessed compliance with measures of guideline development quality (such as transparency in guideline development processes and funding, multidisciplinary author group composition, systematic review of comparative efficacy research) and implementation (such as quality indicators). We compared guidelines from low- and middle-income countries with those from high-income countries. FINDINGS: We identified 82 national and 13 international clinical practice guidelines from 83 countries in 27 languages. Guideline development processes and funding sources were explicitly specified in a smaller proportion of guidelines from low- and middle-income countries (8/29; 28%) relative to high-income countries (35/58; 60%). Fewer guidelines (2/29; 7%) from low- and middle-income countries, relative to high-income countries (22/58; 38%), were authored by a multidisciplinary development group. A systematic review of comparative effectiveness was conducted in 31% (9/29) of low- and middle-income country guidelines versus 71% (41/58) of high-income country guidelines. Only 10% (3/29) of low- and middle-income country and 19% (11/58) of high-income country guidelines described plans to assess quality indicators or recommendation adherence. CONCLUSION: Globally, guideline implementation is inadequately planned, reported and measured. Narrowing disparities in the development and implementation of guidelines in low- and middle-income countries is a priority. Future guidelines should present strategies to implement recommendations and measure feasibility, cost-effectiveness and impact on health outcomes.

RESUMO

The effect of assortative mating on offspring is often not considered. Here, we present data on illness in the spouse and the parents of patients with bipolar disorder as they affect illness in the offspring. A history of psychiatric illness (depression, bipolar disorder, suicide attempt, alcohol abuse, drug abuse, and "other" illness) was elicited for the parents, spouse, and the offspring of 968 patients with bipolar disorder (540 of whom had children) who gave informed consent for participation in a treatment outcome network. Assortative mating for a mood disorder in the spouse and parents in those from the United States (US) was compared to those from the Netherlands and Germany and related to illnesses in the offspring. There was more illness and assortative mating for a mood disorder in both the spouse and patient's parents from the US compared to Europe. In the parents of the US patients, assortative mating for a mood disorder was associated with more depression, bipolar disorder, alcohol, and "other" illness in the offspring. Compared to the Europeans, there was more assortative mating for mood and other disorders in two generations of those from the US. This bilineal positivity for a parental mood disorder was related to more depression a second generation later in the patients' offspring. In clinical assessment of risk of illness in the offspring, the history of psychiatric illness in the spouse and patient's parents might provide additional information.

RESUMO

AIMS: To systematically review the existing trials on optimal serum levels for lithium for maintenance treatment of bipolar disorder and to develop clinical recommendations. METHODS: Systematic literature search. Discussion of major characteristics, limitations, methodological quality, and results of selected trials. Delphi survey consisting of clinical questions and corresponding statements. For statements endorsed by at least 80% of the members, consensus was considered as having been achieved. RESULTS: With strict inclusion criteria no studies could be selected, making it difficult to formulate evidence-based recommendations. After loosening the inclusion criteria 7 trials were selected addressing our aims at least to some extent. Four of these studies suggest better efficacy being associated with lithium serum levels in a range above a lower threshold around 0.45/0.60 and up to 0.80/1.00 mmol/L. These findings support the outcome of the Delphi survey. CONCLUSIONS: For adults with bipolar disorder there was consensus that the standard lithium serum level should be 0.60-0.80 mmol/L with the option to reduce it to 0.40-0.60 mmol/L in case of good response but poor tolerance or to increase it to 0.80-1.00 mmol/L in case of insufficient response and good tolerance. For children and adolescents there was no consensus, but the majority of the members endorsed the same recommendation. For the elderly there was also no consensus, but the majority of the members endorsed a more conservative approach: usually 0.40-0.60 mmol/L, with the option to go to maximally 0.70 or 0.80 mmol/L at ages 65-79 years, and to maximally 0.70 mmol/L over age 80 years.

RESUMO

OBJECTIVE: Bipolar disorder has a wide range of clinical manifestations which may progress over time. The aim of this study was to test the applicability of a clinical staging model for bipolar disorder and to gain insight into the nature of the variables influencing progression through consecutive stages. METHODS: Using retrospectively reported longitudinal life chart data of 99 subjects from the Stanley Foundation Bipolar Network Naturalistic Follow-up Study, the occurrence, duration and timely sequence of stages 2-4 were determined per month. A multi-state model was used to calculate progression rates and identify determinants of illness progression. Stages 0, 1 and several other variables were added to the multi-state model to determine their influence on the progression rates. RESULTS: Five years after onset of BD (stage 2), 72% reached stage 3 (recurrent episodes) and 21% had reached stage 4 (continuous episodes), of whom 8% recovered back to stage 3. The progression from stage 2 to 3 was increased by a biphasic onset for both the depression-mania and the mania-depression course and by male sex. CONCLUSIONS: Staging is a useful model to determine illness progression in longitudinal life chart data. Variables influencing transition rates were successfully identified.

RESUMO

OBJECTIVES: For the first time to present a systematic review of observational studies on the efficiency of lithium monotherapy in comparison with other maintenance mood stabilizers in monotherapy and in combination. METHODS: As part of the International Society for Bipolar Disorders (ISBD) Task Force on Lithium Treatment, we undertook a systematic literature search of non-randomized controlled observational studies on (i) lithium monotherapy vs treatment with another maintenance mood stabilizer in monotherapy and (ii) lithium in combination with other mood stabilizers vs monotherapy. RESULTS: In eight out of nine identified studies including a total of < 14 000 patients, maintenance lithium monotherapy was associated with improved outcome compared with another mood stabilizer in monotherapy, including valproate, lamotrigine, olanzapine, quetiapine, unspecified anticonvulsants, carbamazepine/lamotrigine, unspecified atypical antipsychotics and unspecified antipsychotics. Among the four identified studies including a total of > 4000 patients comparing maintenance combination therapy with maintenance monotherapy, a few combination therapies were found to be superior to monotherapy in some analyses, but many were not. CONCLUSIONS: The results show the superiority in real life of lithium monotherapy compared with monotherapy with other maintenance mood stabilizers. The four largest register-based studies largely addressed confounding, but, as ever, residual confounding cannot be excluded. Nevertheless, the observational findings substantially add to the findings from randomized controlled trials, whose designs often limit the validity of comparison between medicines.

RESUMO

INTRODUCTION: Instead of the typical assessment of risk of illness in the offspring based on a parent with bipolar disorder, we explored the potential multigenerational conveyance across several disorders of the vulnerability to illness in the offspring of a patient with bipolar disorder. METHODS: A total of 968 outpatients (average age 41 years) with bipolar illness gave informed consent and filled out a detailed questionnaire about a family history in their parents, grandparents, and offspring of: depression; bipolar disorder; alcohol abuse; substance abuse; suicide attempt; or "other" illness. Of those with children, 346 were from the USA and 132 were from Europe. Amount and type of illness in progenitors in two and three previous generations were related to offspring illness. RESULTS: The type of illness seen in both prior generations was associated with the same type of illness in the offspring of a bipolar patient, including depression, bipolar disorder, alcohol and substance abuse and "other" illness, but not suicide attempts. There was an impact of multiple generations, such that depression in grandparents and/or great-grandparents increased the risk of depression in the offspring from 12.6% to 41.4%. CONCLUSIONS: A family history of illness burden in prior generations was previously related to an earlier age of onset of bipolar illness in our adult patients with bipolar disorder and is now also found to be related to the incidence of multiple psychiatric illnesses in their offspring. Genetic and epigenetic mechanisms deserve consideration for this multigenerational conveyance of illness vulnerability, and clinical and public health attempts to prevent or slow this transmission are indicated.

RESUMO

INTRODUCTION: Lithium is established as an effective treatment of mania, of depression in bipolar and unipolar disorder, and in maintenance treatment of these disorders. However, due to the necessity of monitoring and concerns about irreversible adverse effects, in particular renal impairment, after long-term use, lithium might be underutilized. METHODS: This study reviewed 6 large observational studies addressing the risk of impaired renal function associated with lithium treatment and methodological issues impacting interpretation of results. RESULTS: An increased risk of renal impairment associated with lithium treatment is suggested. This increased risk may, at least partly, be a result of surveillance bias. Additionally, the earliest studies pointed toward an increased risk of end-stage renal disease associated with lithium treatment, whereas the later and methodologically most sound studies do not. DISCUSSION: The improved renal outcome found in the more recent lithium studies may be a result of improved monitoring and focus on recommended serum levels (preferentially 0.6-0.8 mmol/L) as compared to poorer renal outcome in studies with patients treated in the 1960s to 1980s.

RESUMO

Hippocampal volume deficits have been linked to life stress. However, the degree to which genes and environment influence the association between hippocampal volume and life events is largely unknown. In total, 123 healthy twins from monozygotic and dizygotic twin pairs underwent magnetic resonance imaging (MRI), and 57 healthy twins were interviewed with the Life Events and Difficulties Schedule (LEDS), with an overlap of 54 twins undergoing both MRI and the life events interview. Hippocampal volumes were segmented with Freesurfer software. Data were analyzed with OpenMx software. Smaller hippocampal volume was associated with higher severe life event load (rph = -0.39), where shared environmental factors influencing both measures fully explained the association. Hippocampal volume was not associated with total or mild life event load. Hippocampal volume showed high heritability (range, h(2) : 57%-81%) whereas life event measures were influenced by shared (c(2) ) and unique (e(2) ) environmental factors only (range, c(2) :40%-64%, e(2) : 36%-60%). The results suggested that shared environmental factors influenced the relationship between smaller hippocampal volume and severe (but not mild) stress. This indicated that particularly severe life events that were shared between twins were associated with smaller hippocampal volume. Furthermore, it is suggested to distinguish between mild and severe life events in life event research. © 2016 Wiley Periodicals, Inc.

RESUMO

BACKGROUND: Mindfulness-based cognitive therapy (MBCT) and maintenance antidepressant medication (mADM) both reduce the risk of relapse in recurrent depression, but their combination has not been studied. AIMS: To investigate whether MBCT with discontinuation of mADM is non-inferior to MBCT+mADM. METHOD: A multicentre randomised controlled non-inferiority trial (ClinicalTrials.gov:NCT00928980). Adults with recurrent depression in remission, using mADM for 6 months or longer (n= 249), were randomly allocated to either discontinue (n= 128) or continue (n= 121) mADM after MBCT. The primary outcome was depressive relapse/recurrence within 15 months. A confidence interval approach with a margin of 25% was used to test non-inferiority. Key secondary outcomes were time to relapse/recurrence and depression severity. RESULTS: The difference in relapse/recurrence rates exceeded the non-inferiority margin and time to relapse/recurrence was significantly shorter after discontinuation of mADM. There were only minor differences in depression severity. CONCLUSIONS: Our findings suggest an increased risk of relapse/recurrence in patients withdrawing from mADM after MBCT.

RESUMO

BACKGROUND: The hippocampus is one of the brain regions that is involved in several pathophysiological theories about bipolar disorder (BD), such as the neuroinflammation theory and the corticolimbic metabolic dysregulation theory. We compared hippocampal volume and hippocampal metabolites in bipolar I disorder (BD-I) patients versus healthy controls (HCs) with magnetic resonance imaging (MRI) and spectroscopy (MRS). We post hoc investigated whether hippocampal volume and hippocampal metabolites were associated with microglial activation and explored if potential illness modifying factors affected these hippocampal measurements and whether these were associated with experienced mood and functioning. MATERIALS AND METHODS: Twenty-two BD-I patients and twenty-four HCs were included in the analyses. All subjects underwent psychiatric interviews as well as an MRI scan, including a T1 scan and PRESS magnetic resonance spectroscopy (MRS). Volumetric analysis was performed with Freesurfer. MRS quantification was performed with LC Model. A subgroup of 14 patients and 11 HCs also underwent a successful [(11)C]-(R)-PK11195 neuroinflammation positron emission tomography scan. RESULTS: In contrast to our hypothesis, hippocampal volumes were not decreased in patients compared to HC after correcting for individual whole-brain volume variations. We demonstrated decreased N-acetylaspartate (NAA)+N-acetyl-aspartyl-glutamate (NAAG) and creatine (Cr)+phosphocreatine (PCr) concentrations in the left hippocampus. In the explorative analyses in the left hippocampus we identified positive associations between microglial activation and the NAA+NAAG concentration, between alcohol use and NAA+NAAG concentration, between microglial activation and the depression score and a negative relation between Cr+PCr concentration and experienced occupational disability. Duration of illness associated positively with volume bilaterally. CONCLUSION: Compared to HCs, the decreased NAA+NAAG concentration in the left hippocampus of BD-I patients suggests a decreased neuronal integrity in this region. In addition we found a positive relation between microglial activation and neuronal integrity in vivo, corresponding to a differentiated microglial function where some microglia induce apoptosis while others stimulate neurogenesis.

RESUMO

Increasingly, evidence has been accumulating emphasizing the importance of looking at bipolar disorder (BD) from a neurodevelopmental and transdimensional perspective to better understand its origins and its course. In this overview article, the problems facing pathophysiological psychiatric research in BD are addressed and interpreted in the light of brain complexity. Brain complexity can be split into spatial complexity, which constitutes the physiological levels of the central nervous system (i.e., the genetic, molecular, cellular, neuronal circuit and phenomenological levels), and temporal complexity, that is, neurodevelopment. The consequences of this consideration are discussed and suggestions for clinical practice and pathophysiological psychiatric research are made.

RESUMO

OBJECTIVE: To report use and treatment success rates of medications for bipolar disorder as a function of patients' clinical characteristics. METHOD: Outpatients with bipolar illness diagnosed by SCID were rated by research assistants on the NIMH-LCM and those who had an good response for at least 6months (much or very much improved on the CGI-BP) were considered responders (treatment "success"). Clinical characteristics associated with treatment response in the literature were examined for how often a drug was in a successful regimen when a given characteristic was either present or absent. RESULTS: Lithium was less successful in those with histories of rapid cycling, substance abuse, or (surprisingly) a positive parental history of mood disorders. Valproate was less successful in those with ≥20 prior episodes. Lamotrigine (LTG) was less successful in those with a parental history of mood disorders or in BP-I compared to BP-II disorder. Antidepressants (ADs) had low success rates, especially in those with a history of anxiety disorders. Benzodiazepines had low success rates in those with child abuse, substance use, or ≥20 episodes. Atypical antipsychotics were less successful in the presence of rapid cycling, ≥20 prior episodes, or a greater number of poor prognosis factors. CONCLUSION: Success rates reflect medications used in combination with an average of two other drugs during naturalistic treatment and thus should be considered exploratory. However, the low long-term success rates of drugs (even when used in combination with others) that occurred in the presence of many very common clinical characteristics of bipolar illness speak to the need for the development of alternative treatment strategies.

RESUMO

Replication has been poor for previously reported candidate genes involved in Major Depressive Disorder (MDD). One possible reason is phenotypic and genetic heterogeneity. The present study replicated genetic associations with MDD as defined in DSM-IV and with a more narrowly defined MDD subtype with a chronic and severe course. We first conducted a systematic review of genetic association studies on MDD published between September 2007 and June 2012 to identify all reported candidate genes. Genetic associations were then tested for all identified single nucleotide polymorphisms (SNPs) and the entire genes using data from the GAIN genome-wide association study (MDD: n = 1,352; chronic MDD subsample: n = 225; controls: n = 1,649). The 1,000 Genomes database was used as reference for imputation. From 157 studies identified inthe literature, 81 studies reported significant associations with MDD, involving 245 polymorphisms in 97 candidate genes, from which we were able to investigate 185 SNPs in 89 genes. We replicated nine candidate SNPs in eight genes for MDD and six in five genes for chronic MDD. However, these were not more than expected by chance. At gene level, we replicated 18 genes for MDD and 17 genes for chronic MDD, both significantly more than expected by chance. We showed that replication rates were improved for MDD compared to a previous, highly similar, replication study based on studies published before 2007. Effect sizes of the SNPs and replication rates of the candidate genes were improved in the chronic subsample compared to the full sample. Nonetheless, replication rates were still poor.

RESUMO

OBJECTIVES: There is increasing evidence that both immune and neurochemical alterations are involved in the pathogenesis of bipolar disorder; however, their precise role remains unclear. In this study, we aimed to evaluate neuro-immune changes in a prospective study on children of patients with bipolar disorder. METHODS: Bipolar offspring, from the prospective Dutch bipolar offspring study (n = 140), were evaluated cross-sectionally within a longitudinal context at adolescence, young adulthood, and adulthood. We examined the expression of 44 inflammation-related genes in monocytes, the cytokines pentraxin 3 (PTX3), chemokine ligand 2 (CCL2), and interleukin-1ß (IL-1ß), and brain-derived neurotrophic factor (BDNF) and S100 calcium binding protein B (S100B) in the serum of bipolar offspring and healthy controls. RESULTS: During adolescence, bipolar offspring showed increased inflammatory gene expression in monocytes, high serum PTX3 levels, but normal CCL2 levels. BDNF levels were decreased, while S100B levels were normal. During young adulthood, monocyte activation remained, although to a lesser degree. Serum PTX3 levels remained high, and signs of monocyte migration became apparent through increased CCL2 levels. BDNF and S100B levels were not measured. At adulthood, circulating monocytes had lost their activation state, but CCL2 levels remained increased. Both BDNF and S100B were now increased. Abnormalities were independent of psychopathology state at all stages. CONCLUSIONS: This study suggests an aberrant neuro-immune state in bipolar offspring, which followed a dynamic course from adolescence into adulthood and was present irrespective of lifetime or future mood disorders. We therefore assumed that the aberrant neuro-immune state reflects a general state of vulnerability for mood disorders rather than being of direct predictive value.

RESUMO

OBJECTIVES: Physical or sexual abuse in childhood is known to have an adverse effect on the course of bipolar disorder, but the impact of verbal abuse has not been well elucidated. METHODS: We examined the occurrence and frequency (never to frequently) of each type of abuse in childhood in 634 US adult outpatients (average age 40 years). Patients gave informed consent and provided information about their age of onset and course of illness prior to study entry. RESULTS: Verbal abuse alone occurred in 24% of the patients. Similar to a history of physical or sexual abuse, a history of verbal abuse was related to an earlier age of onset of bipolar disorder and other poor prognosis characteristics, including anxiety and substance abuse comorbidity, rapid cycling, and a deteriorating illness course as reflected in ratings of increasing frequency or severity of mania and depression. CONCLUSIONS: A lasting adverse impact of the experience of verbal abuse in childhood is suggested by its relationship to an earlier age of onset of bipolar disorder, other poor prognosis factors, and a deteriorating course of illness. Verbal abuse is a common confound in comparison groups defined by a lack of physical or sexual abuse. Ameliorating the impact of verbal abuse on the unfolding course of bipolar disorder appears to be an important target of therapeutics and worthy of attempts at primary and secondary prophylaxis. Family-based treatments that focus on psychoeducation, enhancing intra-family communication, and coping skills may be particularly helpful.

RESUMO

The authors assessed how family history loading affected the course of illness in patients from the United States. A total of 676 outpatients with bipolar disorder from the United States rated their illness and provided a parental and grandparental history of mood disorder, substance abuse, and other clinical conditions. A positive family history for each illness was associated with almost all of the seven poor prognosis factors established in the study (abuse in childhood, early onset, anxiety and substance abuse comorbidity, rapid cycling, multiple episodes, and worsening of severity or frequency of episodes). Family history for psychiatric difficulties in parents and grandparents was associated with a more complex and difficult course of bipolar illness.
