    There have been in recent years increasing claims in both popular and professional literature for a connection between bipolar illness and creativity. A review of studies supporting this claim reveals serious flaws in sampling, methodology, presentation of results, and conclusions. Although there is therefore no evidence for etiological or genetic linkages, it is still necessary to explain interrelationships in those creative persons suffering from the illness. Examples of the work in progress of artists with bipolar disorder, Jackson Pollock and Edvard Munch, illustrate the use of healthy and adaptive creative cognition--janusian and homospatial processes--in the former's breakthrough conception during an improvement phase in treatment leading to the development of the Abstract Expressionist Movement and in the latter's transformation of an hallucination into his famous artwork "The Scream." Treatment options that do not produce cognitive effects are important for creative persons with bipolar disorder.

    Although economists have analyzed earnings, unemployment, and labor force participation for those with bipolar illness, occupational choice has yet to be explored. Psychological and medical studies often suggest an association between bipolar illness and creative achievement, but they tend to focus on eminent figures, case studies, or small samples. We seek to examine occupational creativity of non-eminent individuals with bipolar disorder. We use Epidemiologic Catchment Area data to estimate a multinomial logit model matched to an index of occupational creativity. Those with bipolar illness appear to be disproportionately concentrated in the most creative occupational category. Nonparametric kernel density estimates reveal that the densities of the occupational creativity variable for the bipolar and non-bipolar individuals significantly differ in the ECA data, and suggest that the probability of engaging in creative activities on the job is higher for bipolar than non-bipolar workers.

    Alcohol use and abuse was investigated in 73 patients with bipolar I manic-depressive illness who were attending a lithium clinic. Alcohol-related problems were identified in 7 of the male and none of the female patients. Family data revealed a higher morbid risk for alcoholism among relatives of patients with drinking problems than among relatives of patients without drinking problems. Morbid risks for affective disorder for these two groups of relatives were similar, suggesting that alcoholism among relatives of patients with bipolar illness is not solely "genotypically" related to the affective disorder.

    The authors assessed the occurrence of stressful life events before the initial or subsequent episodes of affective illness in a group of 79 bipolar I manic-depressive patients who were attending a lithium clinic. About half of the patients recalled a life event in the 3-month interval before their initial episode; postpartum onset was prominent among these events. Few patients recalled life events for subsequent episodes. Finally, history data did not differentiate patients who recalled life events and those who did not. These data may be useful in assessing environmental antecedents of populations at risk for bipolar illness.

    Bipolar illness is a debilitating neuropsychiatric disorder associated with alterations in the ventral anterior cingulate cortex (vACC), a brain region thought to regulate emotional behavior. Although recent data-driven functional connectivity studies provide evidence consistent with this possibility, the role of vACC in bipolar illness and its pattern of whole brain connectivity remain unknown. Furthermore, no study has established whether vACC exhibits differential whole brain connectivity in bipolar patients with and without co-occurring psychosis and whether this pattern resembles that found in schizophrenia. We conducted a human resting-state functional connectivity investigation focused on the vACC seed in 73 remitted bipolar I disorder patients (33 with psychosis history), 56 demographically matched healthy comparison subjects, and 73 demographically matched patients with chronic schizophrenia. Psychosis history within the bipolar disorder group corresponded with significant between-group connectivity alterations along the dorsal medial prefrontal surface when using the vACC seed. Patients with psychosis history showed reduced connectivity (Cohen's d = -0.69), whereas those without psychosis history showed increased vACC coupling (Cohen's d = 0.8) relative to controls. The vACC connectivity observed in chronic schizophrenia patients was not significantly different from that seen in bipolar patients with psychosis history but was significantly reduced compared with that in bipolar patients without psychosis history. These robust findings reveal complex vACC connectivity alterations in bipolar illness, which suggest differences depending on co-occurrence of lifetime psychosis. The similarities in vACC connectivity patterns in schizophrenia and psychotic bipolar disorder patients may suggest the existence of common mechanisms underlying psychotic symptoms in the two disorders. © The Author 2014.

    Full Text Available The concept of staging as a description of clinical advancement of illness is prevalent and commonly used in medicine. Regarding bipolar mood disorder (BD a staging model assumes a progression from prodromal (at-risk to more severe and treatment-refractory conditions. Four different staging models of BD have been proposed. The concept of Robert Post’s is based on the phenomenon of kindling and neurosensitization, assuming a role of stressors in triggering the first episode of illness, with subsequent persistent changes in the activity of neurones, greater vulnerability to relapse and worse response to treatment. The concept of Anne Duffy’s is based on the research of high risk bipolar offspring and describes the early development of the illness as successive stages, i.e. non-mood disorders, minor mood disorders and acute episodes of illness, starting in childhood, with an attempt to distinguish subtypes of the disease depending on the parent’s response to prophylactic lithium treatment. The model of Michael Berk’s has been constructed in parallel to the therapeutic algorithms and classifies the stages of illness based on clinical features, prognosis, and response to treatment. It also identifies high risk individuals, highlights need of early intervention and is proposed as a course specifier for BD. The model of Flavio Kapczinski’s is based on a phenomenon of allostatic load and evaluation of the changes of biomarkers and cognitive functions during the episode and between episodes. A significant consequence of introducing the staging model is employing treatment which is adequate to a stage of the illness. The model underlines a necessity of early intervention and defines the first episode of the illness as a critical target of it, in a hope to a possibility of prevention against neuroanatomical, neuropsychological, clinical and functional consequence of the illness.

  12. Characterizing Thalamo-Cortical Disturbances in Schizophrenia and Bipolar Illness

    Schizophrenia is a devastating neuropsychiatric syndrome associated with distributed brain dysconnectivity that may involve large-scale thalamo-cortical systems. Incomplete characterization of thalamic connectivity in schizophrenia limits our understanding of its relationship to symptoms and to diagnoses with shared clinical presentation, such as bipolar illness, which may exist on a spectrum. Using resting-state functional magnetic resonance imaging, we characterized thalamic connectivity in 90 schizophrenia patients versus 90 matched controls via: (1) Subject-specific anatomically defined thalamic seeds; (2) anatomical and data-driven clustering to assay within-thalamus dysconnectivity; and (3) machine learning to classify diagnostic membership via thalamic connectivity for schizophrenia and for 47 bipolar patients and 47 matched controls. Schizophrenia analyses revealed functionally related disturbances: Thalamic over-connectivity with bilateral sensory–motor cortices, which predicted symptoms, but thalamic under-connectivity with prefrontal–striatal–cerebellar regions relative to controls, possibly reflective of sensory gating and top-down control disturbances. Clustering revealed that this dysconnectivity was prominent for thalamic nuclei densely connected with the prefrontal cortex. Classification and cross-diagnostic results suggest that thalamic dysconnectivity may be a neural marker for disturbances across diagnoses. Present findings, using one of the largest schizophrenia and bipolar neuroimaging samples to date, inform basic understanding of large-scale thalamo-cortical systems and provide vital clues about the complex nature of its disturbances in severe mental illness.

    Although bipolar disorder (BD) and borderline personality disorder (BPD) share clinical characteristics and frequently co-occur, their interrelationship is controversial. Especially, the differentiation of rapid cycling BD and BPD can be troublesome. This study investigates the relationship between borderline personality features (BPF) and prospective illness course in patients with BD, and explores the effects of current mood state on self-reported BPF profiles. The study included 375 patients who participated in the former Stanley Foundation Bipolar Network. All patients met DSM-IV criteria for bipolar-I disorder (n = 294), bipolar-II disorder (n = 72) or bipolar disorder NOS (n = 9). BPF were assessed with the self-rated Personality Diagnostic Questionnaire. Illness course was based on 1-year clinician rated prospective daily mood ratings with the life chart methodology. Regression analyses were used to estimate the relationships among these variables. Although correlations were weak, results showed that having more BPF at baseline is associated with a higher episode frequency during subsequent 1-year follow-up. Of the nine BPF, affective instability, impulsivity, and self-mutilation/suicidality showed a relationship to full-duration as well as brief episode frequency. In contrast all other BPF were not related to episode frequency. Having more BPF was associated with an unfavorable illness course of BD. Affective instability, impulsivity, and self-mutilation/suicidality are associated with both rapid cycling BD and BPD. Still, many core features of BPD show no relationship to rapid cycling BD and can help in the differential diagnosis.

  3. Profile of aripiprazole in the treatment of bipolar disorder in children and adolescents.

    Bipolar disorder is a pernicious illness. Compared with the later-onset form, early onset bipolar disorder is associated with worse psychosocial outcomes, and is characterized by rapid cycling and increased risks of substance abuse and suicide attempts. Controlling mood episodes and preventing relapse in this group of pediatric patients requires careful treatment. Here, we review the effectiveness of aripiprazole for bipolar disorder in children and adolescents, with discussion of this drug's unique pharmacological profile and various clinical study outcomes. Aripiprazole acts as a serotonin 5-HT2A receptor antagonist, as well as a partial agonist of the serotonin 5-HT1A and dopamine D2 receptors. It can be safely used in children and adolescents, as it is highly tolerated and shows lower rates of the side effects typically observed with other antipsychotic drugs, including sedation, weight gain, hyperprolactinemia, and extrapyramidal syndrome. The presently reviewed randomized controlled trials (RCTs) and non-RCTs generally reported aripiprazole to be effective and well-tolerated in children and adolescents with bipolar disorder. However, due to the limited number of RCTs, the present conclusions must be evaluated cautiously. Furthermore, aripiprazole cannot yet be considered a preferred treatment for children and adolescents with bipolar disorder, as there is not yet evidence that aripiprazole shows greater efficacy compared to other second-generation antipsychotics. Additional data are needed from future head-to-head comparison studies.

    2014-06-01

    Full Text Available Aim: The subject of the research presented in this paper was to analyze the relationships between bipolar disorder (BD and the profile of moral reasoning according to the concept of James Rest. Material and methods: 86 persons took part in the research, including 43 bipolar patients and 43 healthy individuals. To measure the severity of depression and mania symptoms the following scales were used: Hamilton Rating Scale for Depression (HAM-D, Montgomery-Asberg Depression Rating Scale (MADRS and Young Rating Scale for Mania (YMRS. Profile of moral reasoning was defined on the basis of the results obtained in the Defining Issue Test (DIT by James Rest. Results: Statistical analysis showed that there is a relationship between bipolar disorder (and its phases and the profile of moral reasoning: bipolar patients significantly less often than healthy individuals chose answers indicating the postconventional thinking (p=0,000 – and more often – answers indicating stage 3 and those belonging to the anti-institutional thinking index (p=0,000. There was also a relationship shown between the development of moral reasoning and the phase of bipolar disorder: patients in mania less often than per- sons in euthymia chose answers indicating the final stage of moral thinking (p=0,050. There were no significant differences between the results of patients with a depressive episode and the results of patients in mania and between the results of patients with a depressive episode and the results of patients in euthymia. Conclusions: The results suggest that the psychological state of the individual may have an impact on the process of moral reasoning – bipolar disorder may to some extent influence the way of thinking about moral dilemmas. The collected data also seem to emphasize the specificity of the manic phase which is especially worth exploration when conducting further studies.

    Neuropsychological deficits in schizophrenia and affective illnesses have been a topic of increasing research interest for more than two decades. Currently, the cognitive dysfunctions are regarded as an essential element of these illnesses, occurring already in their prodromal phase, with an increment during the course of illness and with some deficits persisting also during the remission period. In schizophrenia, deficits in working memory and executive functions are most frequently demonstrated. In patients with affective illnesses, the initial research focused mainly on depression, where psychomotor slowness, deficits of attention, verbal and working memory and executive functions have been observed. It has been shown that during depression in the course of bipolar affective illness, the cognitive dysfunctions have been more marked as compared with recurrent depression. In this paper, the neuropsychological changes occurring during the period of mania and hypomania have been presented. The disturbances that have been shown most frequently include selective cognitive dysfunctions such as disturbances of attention and learning process, working memory and executive functions. During periods of mania/hypomania, the specific distortions of thinking occur ("anastrophic" thinking), as well as disturbances in the decision making process, connected with increased impulsivity. Another characteristic of the episode of elevated mood has been a change of information processing of affective type, mostly a lower ability for perception and recognition of negative emotions. Among persons with bipolar affective illness, especially during the hypomanic period, an increased level of creativity than in control persons has been observed, what may facilitate higher artistic activity. Recently, the evidence has been accumulated pointing to more severe cognitive dysfunctions in bipolar affective illness, type I (with manic states) compared with bipolar affective illness, type II (with

    Bipolar disorder is an often disabling mental illness with a lifetime prevalence of 1%-2%, a high risk of recurrence of manic and depressive episodes, a lifelong elevated risk of suicide and a substantial heritability. The course of illness is frequently characterised by progressive shortening of interepisode intervals with each recurrence and increasing cognitive dysfunction in a subset of individuals with this condition. Clinically, diagnostic boundaries between bipolar disorder and other psychiatric disorders such as unipolar depression are unclear although pharmacological and psychological treatment strategies differ substantially. Patients with bipolar disorder are often misdiagnosed and the mean delay between onset and diagnosis is 5-10 years. Although the risk of relapse of depression and mania is high it is for most patients impossible to predict and consequently prevent upcoming episodes in an individual tailored way. The identification of objective biomarkers can both inform bipolar disorder diagnosis and provide biological targets for the development of new and personalised treatments. Accurate diagnosis of bipolar disorder in its early stages could help prevent the long-term detrimental effects of the illness.The present Bipolar Illness Onset study aims to identify (1) a composite blood-based biomarker, (2) a composite electronic smartphone-based biomarker and (3) a neurocognitive and neuroimaging-based signature for bipolar disorder.

    The aim of the present study was to characterize the neurocognitive effects of lithium in bipolar disorder to inform clinical and research approaches for further investigation. Key words pertaining to neurocognition in bipolar disorder and lithium treatment were used to search recognized databases to identify relevant literature. The authors also retrieved gray literature (e.g., book chapters) known to them and examined pertinent articles from bibliographies. A limited number of studies have examined the effects of lithium on neurocognition in bipolar disorder and, although in some domains a consistent picture emerges, in many domains the findings are mixed. Lithium administration appears to reshape key components of neurocognition - in particular, psychomotor speed, verbal memory, and verbal fluency. Notably, it has a sophisticated neurocognitive profile, such that while lithium impairs neurocognition across some domains, it seemingly preserves others - possibly those vulnerable to the effects of bipolar disorder. Furthermore, its effects are likely to be direct and indirect (via mood, for example) and cumulative with duration of treatment. Disentangling the components of neurocognition modulated by lithium in the context of a fluctuating and complex illness such as bipolar disorder is a significant challenge but one that therefore demands a stratified and systematic approach, such as that provided by the Lithium Battery. In order to delineate the effects of lithium therapy on neurocognition in bipolar disorder within both research and clinical practice, a greater understanding and measurement of the relatively stable neurocognitive components is needed to examine those that indeed change with lithium treatment. In order to achieve this, we propose a Lithium Battery-Clinical and a Lithium Battery-Research that can be applied to these respective settings. © 2016 John Wiley & Sons A/S.

    To investigate the multifactorial relationship between illness insight, cognitive and emotional processes, and illness characteristics in bipolar disorder patients. Data from 85 euthymic or mildly to moderately depressed bipolar disorder patients were evaluated. Insight was measured using the Mood Disorder Insight Scale (total score and subscale scores: awareness of illness, symptom attribution, and need for treatment). Cognitive and emotional functioning was measured in four domains (processing speed, memory, executive functioning, and emotional learning) in addition to premorbid IQ. Illness characteristics were assessed using the Mini-International Neuropsychiatric Interview, the Questionnaire for Bipolar Disorder, and the Inventory of Depressive Symptomatology-self rating scale. Regression analyses were performed for the whole sample. Post-hoc, interactions with lifetime psychotic features (LPF) were statistically tested and if significant, analyses were repeated for patients with (n = 36) and without (n = 49) LPF separately. In the whole group, better insight was associated with lower processing speed, better memory performance, increased emotional learning, higher level of depressive symptoms, and longer duration of illness. Patients with LPF had worse awareness of illness, but better symptom attribution than patients without LPF. No group differences for need for treatment and overall insight were found. Finally, processing speed significantly predicted subscores for symptom attribution in patients with LPF only. Cognitive functioning as well as impairments in emotional learning and psychotic features independently contributes to impaired insight in bipolar disorder. Processing speed seems to be a key variable in the prediction of insight in patients with LPF and not in patients without LPF. © 2011 John Wiley and Sons A/S.

  9. Fats and factors: lipid profiles associate with personality factors and suicidal history in bipolar subjects.

    Directory of Open Access Journals (Sweden)

    Simon J Evans

    Full Text Available Polyunsaturated fatty acids (PUFA have shown efficacy in the treatment of bipolar disorder, however their specific role in treating the illness is unclear. Serum PUFA and dietary intakes of PUFA associate with suicidal behavior in epidemiological studies. The objective of this study was to assess serum n-3 and n-6 PUFA levels in bipolar subjects and determine possible associations with suicidal risk, including suicidal history and relevant personality factors that have been associated with suicidality. We studied 27 bipolar subjects using the NEO-PI to assess the big five personality factors, structured interviews to verify diagnosis and assess suicidal history, and lipomics to quantify n-3 and n-6 PUFA in serum. We found positive associations between personality factors and ratios of n-3 PUFA, suggesting that conversion of short chain to long chain n-3s and the activity of enzymes in this pathway may associate with measures of personality. Thus, ratios of docosahexaenoic acid (DHA to alpha linolenic acid (ALA and the activity of fatty acid desaturase 2 (FADS2 involved in the conversion of ALA to DHA were positively associated with openness factor scores. Ratios of eicosapentaenoic acid (EPA to ALA and ratios of EPA to DHA were positively associated with agreeableness factor scores. Finally, serum concentrations of the n-6, arachidonic acid (AA, were significantly lower in subjects with a history of suicide attempt compared to non-attempters. The data suggest that specific lipid profiles, which are controlled by an interaction between diet and genetics, correlate with suicidal history and personality factors related to suicidal risk. This study provides preliminary data for future studies to determine whether manipulation of PUFA profiles (through diet or supplementation can affect personality measures and disease outcome in bipolar subjects and supports the need for further investigations into individualized specific modulations of lipid

Compared with the later-onset form, early onset bipolar disorder is associated with worse psychosocial outcomes, and is characterized by rapid cycling and increased risks of substance abuse and suicide attempts. Controlling mood episodes and preventing relapse in this group of pediatric patients requires careful treatment. Here, we review the effectiveness of aripiprazole for bipolar disorder in children and adolescents, with discussion of this drug's unique pharmacological profile and various clinical study outcomes. Aripiprazole acts as a serotonin 5-HT2A receptor antagonist, as well as a partial agonist of the serotonin 5-HT1A and dopamine D2 receptors. It can be safely used in children and adolescents, as it is highly tolerated and shows lower rates of the side effects typically observed with other antipsychotic drugs, including sedation, weight gain, hyperprolactinemia, and extrapyramidal syndrome. The presently reviewed randomized controlled trials (RCTs and non-RCTs generally reported aripiprazole to be effective and well-tolerated in children and adolescents with bipolar disorder. However, due to the limited number of RCTs, the present conclusions must be evaluated cautiously. Furthermore, aripiprazole cannot yet be considered a preferred treatment for children and adolescents with bipolar disorder, as there is not yet evidence that aripiprazole shows greater efficacy compared to other second-generation antipsychotics. Additional data are needed from future head-to-head comparison studies. Keywords: child, mania, mixed state

    Benzodiazepines are widely prescribed for patients with bipolar disorders in clinical practice, but very little is known about the subtypes of patients with bipolar disorder or aspects of bipolar illness that contribute most to benzodiazepine use. We examined the prevalence of and factors associated with benzodiazepine use among 482 patients with bipolar I or II disorder enrolled in the Bipolar CHOICE study. Eighty-one subjects were prescribed benzodiazepines at study entry and were considered benzodiazepine users. Stepwise logistic regression was used to model baseline benzodiazepine use versus nonuse, using entry and exit criteria of P benzodiazepine users were prescribed a significantly higher number of other psychotropic medications and were more likely to be prescribed lamotrigine or antidepressants as compared with benzodiazepine nonusers. Benzodiazepine users were more likely to have a diagnosis of bipolar I disorder and comorbid anxiety disorder, but not comorbid alcohol or substance use disorders. Benzodiazepine users also had experienced more anxiety and depressive symptoms and suicidality, but not irritability or manic symptoms, than did benzodiazepine nonusers. In the multivariate model, anxiety symptom level (regardless of diagnosis), lamotrigine use, number of concomitant psychotropic medications, college education, and high household income predicted benzodiazepine use. Benzodiazepine use in patients with bipolar disorders is associated with greater illness complexity as indicated by a higher number of concomitant psychotropic medications and higher anxiety symptom burden, regardless of a comorbid anxiety disorder diagnosis. Demographic factors were also important determinants of benzodiazepine use, which may be related to access to care and insurance coverage for benzodiazepines.

    To compare the prevalence and pattern of comorbid substance use disorders (SUD) between patients with schizophrenia, bipolar disorder, and depressive illness. Data on presence of alcohol use disorder (AUD) and non-alcohol drug use disorder (DUD) were retrieved from the Norwegian Patient Register for individuals born between 1950 and 1989 who in the period 2009-2013 were diagnosed with schizophrenia, bipolar disorder or depressive illness according to the 10th version of the WHO International Classification of Diseases. The prevalence of AUD only, DUD only, or both was compared between men and women across age and diagnostic groups. The prevalence of SUD was 25.1 % in schizophrenia (AUD: 4.6 %, DUD: 15.6 %, AUD and DUD: 4.9 %), 20.1 % in bipolar disorder (AUD: 8.1 %, DUD: 7.6 %, AUD and DUD: 4.4 %), and 10.9 % in depressive illness (AUD: 4.4 %, DUD: 4.3 %, AUD and DUD: 2.2 %). Middle-aged men with bipolar disorder had the highest prevalence of AUD (19.1 %) and young men with schizophrenia had the highest prevalence of DUD (29.6 %). Of the specific DUDs, all but sedative use disorder were more prevalent in schizophrenia than the other groups. Cannabis and stimulant use disorder was found among 8.8 and 8.9 %, respectively, of the men with schizophrenia. The alarmingly high prevalence of DUD among young patients with severe mental disorders should encourage preventive efforts to reduce illicit drug use in the adolescent population.

    Lithium's efficacy in prophylaxis of mood episodes in bipolar disorder (BD) is well established in the clinical trial setting, but may be less robust in routine clinical practice. We compared illness recurrence in bipolar patients naturalistically continued on or discontinued from lithium after an extended period of clinical stability on lithium monotherapy, and evaluated other potential risk factors for relapse. We followed 213 patients who were stable for 2 years on lithium monotherapy following resolution of acute symptoms marking their last manic episode. Based upon patient preference and clinical judgment, 159 patients were continued on lithium monotherapy and 54 patients were slowly discontinued. Survival differences between the continued and discontinued groups were assessed using the Kaplan-Meier product limit method, and risk factors for relapse were evaluated in Cox proportional hazards regression. Patients continued on lithium prophylaxis experienced risk of recurrence equivalent to a third of that suffered by discontinued patients during the first year of treatment (0.15 versus 0.45), and significant survival differences persisted throughout follow-up. Median survival time to illness recurrence for patients continued on lithium was 7.33 years [95% confidence interval (CI) 5.67-9.67]; that for patients discontinued from lithium was 1.33 years (95% CI 0.33-2.33). After controlling for all significant covariates, lithium discontinuation was associated with a hazard ratio of 4.85. Inter-episode manic and depressive symptoms conferred increased risk for subsequent recurrence of illness in both groups, while lower lithium levels recorded during the two years of clinical stability preceding study onset were protective. Despite considerable rates of illness recurrence in both groups, those who continued on lithium sustained markedly lower rates of recurrence over a lengthy follow-up period.

    Studies indicate that comorbid anxiety disorders predict a more severe course of illness in bipolar disorder (BD). The relatively high prevalence of social anxiety in BD points to the potential role that socio-cultural factors, such as stigma, play in exacerbating the progression of this disorder. Stigma creates social anxiety in affected individuals because it essentially forces them into a vulnerable social status that is marked by public disgrace. Although the etiology of debilitating social anxiety in BD may involve multiple factors, stigma deserves particular clinical attention because research in this area indicates that it is common and its internalization is associated with poor outcome. We conducted a literature review using search terms related to stigma, social anxiety, bipolar disorder, illness severity, and outcomes. The electronic databases searched included PsychINFO, PubMed, JSTOR, and EBSCOhost Academic Search Complete with limits set to include articles published in English. The literature indicates that internalized stigma often triggers the core psychological experiences of social anxiety and is highly correlated with clinical and functional outcome in BD. On a psychological level, internalized stigma and social anxiety can create distress that triggers symptoms of BD. From a biological perspective, stigma constitutes a chronic psychosocial stressor that may interact with the pathophysiology of BD in inflammatory ways. The connection between stigma and social anxiety, and their combined effects on people with BD, carries important implications for psychiatric care. To obtain an accurate clinical formulation, initial evaluations may seek to examine stigma-related experiences and determine their relationship to anxiety symptoms and psychosocial functioning. In addition, direct interventions for reducing the ill effects of stigma in BD deserve clinical attention, because they may carry the potential to enhance outcomes.

    2013-11-01

    This qualitative study explores (1) how members of the Dutch Association for People with Bipolar Disorder explain the affliction of bipolar disorder; (2) the relationship between genetic, environmental and personal factors in these explanations and (3) the relationship between illness explanations, self-management and identity. A total of 40 participants took part in seven different focus group discussions. The results demonstrate that there are two different explanatory idioms, each one centred around an opposing concept, that is, susceptibility and disease. Individuals who construct explanations around the concept of 'disease' attach more importance to 'genes and chemicals' than to environmental components in the onset of the disorder, whereas individuals adhering to the central concept of 'susceptibility' tend to do this much less. Compared with individuals using the 'susceptibility' idiom, those who use a 'disease' idiom tend to observe fewer possibilities for self-management and are less inclined to construct normalcy through a quest for personal growth. Stories of suffering seem more integral to the 'disease' idiom than to the 'susceptibility' idiom. The 'disease' idiom seems less integrated in a contemporary surveillance psychiatric discourse than the 'susceptibility' idiom; however, both vocabularies can offer normative constraints.

    In recent years evidence of an association between bipolar disorder (BD), and specific neuropsychological impairment and familial transmission of BD has been mounting. The aim of this study was to identify the clinical and neuropsychological features of BD in adolescents, to assess the clinical and neuropsychological parameters in adolescents with a high risk of familial transmission of BD, and to identify probable early markers of the disorder. The study included 25 patients aged 12-18 years that were diagnosed as BD (case group), 25 adolescents without a mood disorder that had a parent and/or sibling diagnosed as BD, (risk group), and 25 typically developing adolescents (control group). To determine neuropsychological profiles the participants were administered the Wisconsin Card Sorting Test (WCST), Stroop Color Word Test (SCWT), and Continuous Performance Test (CPT), and to evaluate clinical and behavioral profiles the Children's Depression Inventory (CDI), Parent-Young Mania Rating Scale (P-YMRS), Youth Self-Report (YSR), and Conners' Parent Rating Scale (CPRS-48) were administered. The case group performed significantly lower on the WCST, SCWT, and CPT in terms of executive and attention functions, whereas there wasn't a difference between the risk group and control group. In addition, significantly more of the adolescents in the case and risk groups had clinical and behavioral problems than those in the control group. The findings show that behavioral and clinical problems were more common in the risk group than in the control group, and that the frequency of attention and executive function impairment was similar in both of those groups. The findings suggest that BD itself may be associated with attention and executive function impairments, whereas a familial risk of BD may be associated with some behavioral problems. Follow-up and neuroimaging studies conducted with a larger number of participants, and neuropsychological test profiles may provide more

    Cannabis use disorders (CUD) may influence the course of bipolar disorder (BD), but key confounding factors such as tobacco smoking have not been adequately addressed. This study examined whether CUD was associated with a more severe illness course in tobacco smoking BD patients. A sample of French and Norwegian tobacco smoking patients with BD I and II (N=642) was investigated. DSM-IV diagnoses and other characteristics were obtained through personal interviews using structured questionnaires. The association between CUD and illness course was assessed in regression analyses. In bivariate analyses, CUD was associated with earlier BD onset, higher frequency of manic (in BD I) and depressive episodes and hospitalizations per illness year, and a higher occurrence of psychotic episodes. After controlling for potential confounders, the relationships with earlier BD onset (B=-5.60 95% CI=-7.65 to -3.64), and increased rates of manic episodes (OR=1.93, 95% CI: 1.15 to 3.23) and hospitalizations (OR=2.93, 95% CI: 1.85 to 4.64) remained statistically significant. Despite the multivariate approach, differences between the two samples may lead to spurious findings related to hidden confounders. Substance use and mood episode information was collected retrospectively, and potential birth cohort effects could not be controlled for. Studies have found associations between tobacco smoking and poorer outcomes in BD. In this study on tobacco smoking BD patients we report an association between CUD and illness severity, suggesting that CUD exacerbates the disease evolution independently of tobacco smoking. Specific treatment and prevention programs addressing CUD in BD patients are warranted. Copyright © 2015 Elsevier B.V. All rights reserved.

    OBJECTIVE: Transcriptomic biomarkers of psychiatric diseases obtained from a query of peripheral tissues that are clinically accessible (e.g., blood cells instead of post-mortem brain tissue) have substantial practical appeal to discern the molecular subtypes of common complex diseases such as major psychosis. To this end, spliceome-profiling is a new methodological approach that has considerable conceptual relevance for discovery and clinical translation of novel biomarkers for psychiatric illnesses. Advances in microarray technology now allow for improved sensitivity in measuring the transcriptome while simultaneously querying the "exome" (all exons) and "spliceome" (all alternatively spliced variants). The present study aimed to evaluate the feasibility of spliceome-profiling to discern transcriptomic biomarkers of psychosis. METHODS: We measured exome and spliceome expression in peripheral blood mononuclear cells from 13 schizophrenia patients, nine bipolar disorder patients, and eight healthy control subjects. Each diagnostic group was compared to each other, and the combined group of bipolar disorder and schizophrenia patients was also compared to the control group. Furthermore, we compared subjects with a history of psychosis to subjects without such history. RESULTS: After applying Bonferroni corrections for the 21,866 full-length gene transcripts analyzed, we found significant interactions between diagnostic group and exon identity, consistent with group differences in rates or types of alternative splicing. Relative to the control group, 18 genes in the bipolar disorder group, eight genes in the schizophrenia group, and 15 genes in the combined bipolar disorder and schizophrenia group appeared differentially spliced. Importantly, thirty-three genes showed differential splicing patterns between the bipolar disorder and schizophrenia groups. More frequent exon inclusion and/or over-expression was observed in psychosis. Finally, these observations are

Twenty three euthymic patients with bipolar disorder were matched, on a case-by-case basis, to twenty-one healthy subjects in the control group, for the presence of the symptoms of depression. The patients and the control group were tested with a battery of neuropsychological tests. Results. Impairments were found in the patients compared with the control group in tests of verbal learning and memory and in tests of executive function. Verbal learning and memory, as well as executive functions, did not correlate either with the clinical indices of patients, or with the demographic and baseline clinical measures of depression. Conclusion. Impaired verbal learning and memory and executive functions may represent a trait rather than the state variables in bipolar disorder.

    The molecular mechanisms of major mental illnesses, such as schizophrenia and bipolar disorder, are unclear. To address this fundamental question, many groups have studied molecular expression profiles in postmortem brains and other tissues from patients compared with those from normal controls. Development of unbiased high-throughput approaches, such as microarray, RNA-seq, and proteomics, have supported and facilitated this endeavor. In addition to genes directly involved in neuron/glia signaling, especially those encoding for synaptic proteins, genes for metabolic cascades are differentially expressed in the brains of patients with schizophrenia and bipolar disorder, compared with those from normal controls in DNA microarray studies. Here we propose the importance and usefulness of genetic mouse models in which such differentially expressed molecules are modulated. These animal models allow us to dissect the mechanisms of how such molecular changes in patient brains may play a role in neuronal circuitries and overall behavioral phenotypes. We also point out that models in which the metabolic genes are modified are obviously untested from mental illness viewpoints, suggesting the potential to re-address these models with behavioral assays and neurochemical assessments.

    Numbers of gene expression profiling studies of bipolar disorder have been published. Besides different array chips and tissues, variety of the data processes in different cohorts aggravated the inconsistency of results of these genome-wide gene expression profiling studies. By searching the gene expression databases, we obtained six data sets for prefrontal cortex (PFC) of bipolar disorder with raw data and combinable platforms. We used standardized pre-processing and quality control procedures to analyze each data set separately and then combined them into a large gene expression matrix with 101 bipolar disorder subjects and 106 controls. A standard linear mixed-effects model was used to calculate the differentially expressed genes (DEGs). Multiple levels of sensitivity analyses and cross validation with genetic data were conducted. Functional and network analyses were carried out on basis of the DEGs. In the result, we identified 198 unique differentially expressed genes in the PFC of bipolar disorder and control. Among them, 115 DEGs were robust to at least three leave-one-out tests or different pre-processing methods; 51 DEGs were validated with genetic association signals. Pathway enrichment analysis showed these DEGs were related with regulation of neurological system, cell death and apoptosis, and several basic binding processes. Protein-protein interaction network further identified one key hub gene. We have contributed the most comprehensive integrated analysis of bipolar disorder expression profiling studies in PFC to date. The DEGs, especially those with multiple validations, may denote a common signature of bipolar disorder and contribute to the pathogenesis of disease.

  14. A survey of genomic studies supports association of circadian clock genes with bipolar disorder spectrum illnesses and lithium response.

    Full Text Available Circadian rhythm abnormalities in bipolar disorder (BD have led to a search for genetic abnormalities in circadian "clock genes" associated with BD. However, no significant clock gene findings have emerged from genome-wide association studies (GWAS. At least three factors could account for this discrepancy: complex traits are polygenic, the organization of the clock is more complex than previously recognized, and/or genetic risk for BD may be shared across multiple illnesses. To investigate these issues, we considered the clock gene network at three levels: essential "core" clock genes, upstream circadian clock modulators, and downstream clock controlled genes. Using relaxed thresholds for GWAS statistical significance, we determined the rates of clock vs. control genetic associations with BD, and four additional illnesses that share clinical features and/or genetic risk with BD (major depression, schizophrenia, attention deficit/hyperactivity. Then we compared the results to a set of lithium-responsive genes. Associations with BD-spectrum illnesses and lithium-responsiveness were both enriched among core clock genes but not among upstream clock modulators. Associations with BD-spectrum illnesses and lithium-responsiveness were also enriched among pervasively rhythmic clock-controlled genes but not among genes that were less pervasively rhythmic or non-rhythmic. Our analysis reveals previously unrecognized associations between clock genes and BD-spectrum illnesses, partly reconciling previously discordant results from past GWAS and candidate gene studies.

  15. The many forms of bipolar disorder: a modern look at an old illness.

    Bipolar disorder continues to be underrecognized, despite being known for 2000 years. Mania, the fullest expression of the disease affects approximately 1% of the population; the less-than-manic forms of the disease dominated by depressive episodes have recently been found to be more common, affecting 4-5% of the population. In reviewing the international literature on this broadened bipolar spectrum, this paper pays particular tribute to the French EPIDEP and EPIMAN studies and Italo-American collaboration which have generated the largest set of systematic data on the new clinical portrait of bipolar disorders. Early detection is crucial, because untreated bipolar disorder has a high mortality rate. A review of the diagnostic criteria for the various subtypes of bipolar disorder has identified several factors that interfere with making an accurate diagnosis. These include age at onset, ethnic differences, co-morbidity (particularly substance abuse and alcoholism), and the broad range of clinical presentations. Moreover, symptoms frequently overlap with those of other psychiatric disorders including schizophrenia, attention-deficit disorder and personality disorders. Misdiagnosis is a major factor leading to a poor outcome for patients. Accurate identification and diagnosis of the different forms of mania can lead to specific treatment choices that may improve prognosis. Particularly important are recent data indicating reduced mortality with a variety of psychopharmacologic agents including, but not limited to, lithium and valproate.

    The gut microbiome is emerging as an important factor in regulating mental health yet it remains unclear what the target should be for psychiatric treatment. We aimed to elucidate the complement of the gut-microbiome community for individuals with bipolar disorder relative to controls; and test for relationships with burden of disease measures. We compared the stool microbiome from individuals with bipolar disorder (n = 115) and control subjects (n = 64) using 16S ribosomal RNA (rRNA) gene sequence analysis. Analysis of molecular variance (AMOVA) revealed global community case-control differences (AMOVA p = 0.047). Operational Taxonomical Unit (OTU) level analysis revealed significantly decreased fractional representation (p bipolar disorder, the fractional representation of Faecalibacterium associated with better self-reported health outcomes based on the Short Form Health Survey (SF12); the Patient Health Questionnaire (PHQ9); the Pittsburg Sleep Quality Index (PSQI); the Generalized Anxiety Disorder scale (GAD7); and the Altman Mania Rating Scale (ASRM), independent of covariates. This study provides the first detailed analysis of the gut microbiome relationships with multiple psychiatric domains from a bipolar population. The data support the hypothesis that targeting the microbiome may be an effective treatment paradigm for bipolar disorder. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Lithium is the drug of choice for the treatment of bipolar affective disorder. To define lithium therapeutic profile and adverse reactions to its use in patients with bipolar affective disorder in Colombia. We conducted an observational retrospective cohort study between January 1 and December 31, 2013, which included patients with a diagnosis of bipolar disorder treated with lithium carbonate in 25 Colombian cities; we evaluated socio-demographic variables, lithium dose, co-medication, drug interactions and adverse reactions. A multivariate analysis was done using SPSS 22.0. The 331 patients had an average age of 44.5 ± 13.9 years; 59.2% were women. The mean dose of lithium was 898 ± 294 mg/day; 22% received doses lower than recommended, and patients had received lithium for 38.0 ± 39.5 months (range: 12-159 months). Lithium levels in blood had been measured only in 13.5% of patients; 71.3% of them had received adjuvant therapy for bipolar disorder with other drugs, especially clozapine (16.6%) and valproic acid (16.6%). The main comorbidities were hypothyroidism (18.1%) and hypertension (12.7%); 390 potentially toxic drug interactions were found, and adverse reactions were reported in 1.2% of patients. A statistically significant association was found between a lower risk of combination therapy and receiving treatment in the cities of Bogotá (OR=0.4, p=0.025), Cartagena (OR=0.3, p=0.015) and Ibagué (OR=0.3, p=0.025). Lithium was generally used at recommended doses and intervals, but a significant percentage of patients received lower doses than those recommended, and it was not possible to compare with lithium levels in blood. Adverse reactions and blood lithium levels reporting should be improved in patients with bipolar disorder in Colombia.

    Full Text Available Objective: Temperament originates in the brain structure, and individual differences are attributable to neural and physiological function differences. It has been suggested that temperament is associated with metabolic syndrome (MetS markers, which may be partly mediated by lifestyle and socioeconomic status. Therefore, we aim to compare MetS prevalence between different affective temperamental profiles for each season in bipolar patients. Methods: Twenty-six bipolar type-I patients of a specialized outpatient mood disorder unit were evaluated for MetS according to new definition proposed by the International Diabetes Federation in the four seasons of a year. Temperament was assessed using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego - autoquestionnaire version (TEMPS-A. Results: The proportions of MetS were 19.2, 23.1, 34.6, and 38.5% in the summer, fall, spring, and winter, respectively. Only depressive temperament scores were higher (p = 0.002 during the winter in patients with MetS. Conclusion: These data suggest that depressive temperament profiles may predispose an individual to the development of MetS in the winter.

    Schizophrenia affecting almost 1% and bipolar disorder affecting almost 3%-5% of the global population constitute two severe mental disorders. The catecholaminergic and the serotonergic pathways have been proved to play an important role in the development of schizophrenia, bipolar disorder, and other related psychiatric disorders. The aim of the study was to perform and interpret the results of a comparative genomic profiling study in schizophrenic patients as well as in healthy controls and in patients with bipolar disorder and try to relate and integrate our results with an aberrant amino acid transport through cell membranes. In particular we have focused on genes and mechanisms involved in amino acid transport through cell membranes from whole genome expression profiling data. We performed bioinformatic analysis on raw data derived from four different published studies. In two studies postmortem samples from prefrontal cortices, derived from patients with bipolar disorder, schizophrenia, and control subjects, have been used. In another study we used samples from postmortem orbitofrontal cortex of bipolar subjects while the final study was performed based on raw data from a gene expression profiling dataset in the postmortem superior temporal cortex of schizophrenics. The data were downloaded from NCBI's GEO datasets.

    Based on analytical consideration and numerical simulations, it is shown how the mutually adjusted doping and stoichiometric profile results in improved frequency response and current gain in Si1-x Ge x -based heterojunction bipolar transistor. The closed-form expressions are derived for the dopant distribution within a certain mobility model which is parametrized in terms of the impurity concentration and stoichiometric grading on the same footing. With proper parametrization of the mobility, the method is suitable in both limits of high alloy scattering/low crystal ordering and low alloy scattering/highly ordered stoichiometrically graded structure. The work is corroborated by device simulations of a single-side HBT 30% stoichiometrically graded base, with detailed IV-curve, Gummel and AC analysis. It is shown that the distinct impurity distribution results in a reduced space-charge region, contributes to an effective electric field assisting the diffusion of the minority carriers and results in the saturation current density increased by 50%, the AC gain increased by 90%, the four-fold increase of the DC current gain, and improves the transition frequency from 274 to 358 GHz as compared to the case of the uniformly distributed acceptors. The obtained results may serve as a practical guide in design of highly-graded heterojunction bipolar transistors with efficient frequency response, high gain and enhanced power.

    We aimed to evaluate the Child Behavior Checklist (CBCL) profiles in youths with bipolar and depressive disorders. Seventy-four subjects with a mean age of 14.9±1.6years (36 boys) with mood disorders and their parents were recruited from September 2011 to June 2013 in the Department of Psychiatry, Asan Medical Center, Seoul, Korea. Diagnosis of mood disorder and comorbid psychiatric disorder was confirmed by child psychiatrists using the Schedule for Affective Disorders and Schizophrenia for School Age Children - Present and Lifetime version (K-SADS-PL). The parents of the subjects completed the Parent General Behavior Inventory-10-item Mania Scale (P-GBI-10M), Parent-version of Mood Disorder Questionnaire (P-MDQ), ADHD rating scale (ARS) and CBCL. The adolescents completed the 76-item Adolescent General Behavior Inventory (A-GBI), Beck Depression Inventory (BDI), and Adolescent-version of Mood Disorder Questionnaire (A-MDQ). When adjusted for gender and the comorbidity with ADHD, the Withdrawn and Anxious/Depressed subscale scores of the CBCL were higher in subjects with bipolar disorder than in those with depressive disorder. Higher scores of A-GBI Depressive subscale, A-MDQ and BDI were shown in subjects with bipolar disorder than in those with depressive disorder. There was no significant difference on CBCL-DP, P-GBI-10M, P-MDQ, A-GBI Hypomanic/Biphasic subscale and ARS between two groups. All eight subscales of the CBCL positively correlated with the P-GBI-10M and P-MDQ scores, and seven of all eight subscales of the CBCL positively correlated with A-GBI Depressive and Hypomanic/Biphasic subscales. The BDI score was positively associated with the Withdrawn, Somatic Complaints, Anxious/Depressed, and Social Problems subscale scores. CBCL-DP score was strongly correlated with manic/hypomanic symptoms measured by P-GBI-10M and P-MDQ (r=0.771 and 0.826). This study suggests that the CBCL could be used for measuring mood symptoms and combined psychopathology

    Bipolar disorder is a serious psychiatric condition that may have onset in childhood. It is important for physicians to recognize the symptoms of bipolar disorder in children and adolescents in order to accurately diagnose this illness early in its course. Evidence regarding the efficacy of various treatments is necessary to guide the management of bipolar disorder in youth. For example, several medications commonly used for adults with bipolar disorder have not shown efficacy for children and adolescents with bipolar disorder. This article reviews the prevalence, diagnosis, course, and treatment of bipolar disorder in children and adolescents and provides physicians with information that will aid in diagnosis and treatment.

    This study aimed to identify profiles of functioning and quality of life (QOL) in depression (MDD), bipolar disorder (BD) and healthy adults, as well as the clinical, demographic and cognitive variables associated with each of these profiles. Participants completed the WHODAS 2.0 and WHOQOL-BREF, which were submitted to latent profile analysis. The four cluster solution provided the best fit for our data. Cluster 1 consisted mostly of healthy adults, and had the highest functioning and QOL. Clusters 2 contained older patients with subclinical depressive symptoms and psychiatric comorbidities, whose impairments in QOL and functioning were associated with mood symptoms and several cognitive abilities. Patients with MDD, BDI or BDII with mild to moderate depression, such as those in cluster 3, may benefit more significantly from interventions in cognitive flexibility, inhibition, planning, and sustained attention. Lastly, patients with mood disorders and clinically significant levels of depression, as well as a history of suicide attempts, like those in cluster 4, may benefit from interventions aimed at working memory, inhibitory control, and cognitive flexibility; that is, the three core executive functions. These findings should be further investigated, and used to guide treatments for patients with mood disorders and different patterns of functional impairment.

    The treatment of major mental disorders usually combines medical and psychosocial interventions. The present study reviews research pertaining to the efficacy of group psychosocial interventions for people with psychotic illness. An electronic search was conducted through Medline and PsychINFO to identify articles relevant to group therapy for people with schizophrenia and bipolar affective disorder. Articles published in the English language, between January 1986 and May 2006, were considered. Studies were included if they had a control group and at least 20 participants. The search resulted in 23 articles concerning patients with schizophrenia and five concerning patients with bipolar affective disorder. The therapeutic approach in the majority of the studies was along the lines of cognitive behaviour therapy and psychoeducation. All studies reported improvement in at least one parameter. Most of them report improvement in skills and overall functioning.

    Bipolar disorder is a highly heritable illness that onsets in adolescence and young adulthood. We examined gene expression (mRNA) and protein levels of candidate immune and neurotrophic markers in well-characterized offspring of bipolar parents in order to identify reliable indicators of illness risk status and the early clinical stages of illness development. We measured mRNA expression and protein levels in candidate immune (TNF-α, IL-1β, IL-10, IFN-δ) and neurotrophic (brain-derived neurotrophic factor (BDNF)) markers from plasma. High-risk offspring were identified from families in which one parent had confirmed bipolar disorder. Control offspring were identified from families in which neither parent met lifetime criteria for a major psychiatric disorder. All parental Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnoses were based on Schedule for Affective Disorders - Lifetime Version (SADS-L) interviews and blind consensus review. As part of an ongoing study, all offspring were prospectively assessed using KSADS-PL format interviews and diagnoses confirmed on blind consensus review. High-risk offspring had significantly increased IL-6 (p = 0.050) and BDNF (p = 0.006) protein levels compared to controls. Those high-risk offspring in earlier compared to later clinical stages of illness development had higher IL-6 (p = 0.050) and BDNF (p = 0.045) protein levels. After adjustments, only differences in BDNF protein levels remained significant. There was a moderating effect of the BDNF genotype on both gene expression and protein levels in high-risk compared to control offspring. The BDNF genotype also moderated the association between clinical stage and gene expression levels in high-risk offspring. These findings provide support for detectable differences in candidate immune and neurotrophic markers in individuals at high risk of developing bipolar disorder and for detectable changes over the clinical stages

    Bipolar Disorder (BD) and schizophrenia are included in the group of severe mental illness and are main causes of disability and morbidity in the local population due to the bio-psycho-social implications in patients. In the last 20 years or so, adjunctive psychological interventions been studied with the purpose of decreasing recurrences, stabilising the course of the disease, and improving the functionality in these patients. To analyse the psychological effect of a multimodal intervention (MI) vs a traditional intervention (TI) program in BD I and schizophrenic patients. A prospective, longitudinal, therapeutic-comparative study was conducted with 302 patients (104 schizophrenic and 198 bipolar patients) who were randomly assigned to the MI or TI groups of a multimodal intervention program PRISMA. The MI group received care from psychiatry, general medicine, neuropsychology, family therapy, and occupational therapy. The TI group received care from psychiatry and general medicine. The Hamilton and Young scales, and the Scales for the Assessment of Negative Symptoms (SANS) and Postive Symptoms (SAPS) were used on bipolar and schizophrenic patients, respectively. The scales AQ-12, TEMPS-A, FAST, Zuckerman sensation seeking scale, BIS-11, SAI-E and EEAG were applied to measure the psychological variables. The scales were performed before and after the interventions. The psychotherapy used in this study was cognitive behavioural therapy. There were statistically significant differences in socio-demographic and clinical variables in the schizophrenia and bipolar disorder group. There were no statistically significant differences in the psychological scales after conducting a multivariate analysis between the intervention groups and for both times (initial and final). This study did not show any changes in variables of psychological functioning variables between bipolar and schizophrenic groups, who were subjected to TI vs MI (who received cognitive behavioural therapy

    Full Text Available Abstract Background Patients with acute mania respond differentially to treatment and, in many cases, fail to obtain or sustain symptom remission. The objective of this exploratory analysis was to characterize response in bipolar disorder by identifying groups of patients with similar manic symptom response profiles. Methods Patients (n = 222 were selected from a randomized, double-blind study of treatment with olanzapine or divalproex in bipolar I disorder, manic or mixed episode, with or without psychotic features. Hierarchical clustering based on Ward's distance was used to identify groups of patients based on Young-Mania Rating Scale (YMRS total scores at each of 5 assessments over 7 weeks. Logistic regression was used to identify baseline predictors for clusters of interest. Results Four distinct clusters of patients were identified: Cluster 1 (n = 64: patients did not maintain a response (YMRS total scores ≤ 12; Cluster 2 (n = 92: patients responded rapidly (within less than a week and response was maintained; Cluster 3 (n = 36: patients responded rapidly but relapsed soon afterwards (YMRS ≥ 15; Cluster 4 (n = 30: patients responded slowly (≥ 2 weeks and response was maintained. Predictive models using baseline variables found YMRS Item 10 (Appearance, and psychosis to be significant predictors for Clusters 1 and 4 vs. Clusters 2 and 3, but none of the baseline characteristics allowed discriminating between Clusters 1 vs. 4. Experiencing a mixed episode at baseline predicted membership in Clusters 2 and 3 vs. Clusters 1 and 4. Treatment with divalproex, larger number of previous manic episodes, lack of disruptive-aggressive behavior, and more prominent depressive symptoms at baseline were predictors for Cluster 3 vs. 2. Conclusion Distinct treatment response profiles can be predicted by clinical features at baseline. The presence of these features as potential risk factors for relapse in patients who have responded to treatment

    The efficacy of lithium carbonate as a prophylactic drug against depression in bipolar manic depressive patients was assessed through a double-blind, placebo-controlled study of patients who had histories of recurrent depressions and hypomanias ("bipolar II"). The results revealed that treatment with lithium carbonate resulted in a reduction in the frequency of depressive attacks was observed with lithium carbonate treatment during the study (mean length of study, approximately 16 months), although there was a suggestion that the depressive attacks that occurred during treatment with lithium carbonate might be less severe than with placebo treatment.

  17. Utilization of never-medicated bipolar disorder patients towards development and validation of a peripheral biomarker profile.

    Directory of Open Access Journals (Sweden)

    Catherine L Clelland

    Full Text Available There are currently no biological tests that differentiate patients with bipolar disorder (BPD from healthy controls. While there is evidence that peripheral gene expression differences between patients and controls can be utilized as biomarkers for psychiatric illness, it is unclear whether current use or residual effects of antipsychotic and mood stabilizer medication drives much of the differential transcription. We therefore tested whether expression changes in first-episode, never-medicated BPD patients, can contribute to a biological classifier that is less influenced by medication and could potentially form a practicable biomarker assay for BPD. We employed microarray technology to measure global leukocyte gene expression in first-episode (n=3 and currently medicated BPD patients (n=26, and matched healthy controls (n=25. Following an initial feature selection of the microarray data, we developed a cross-validated 10-gene model that was able to correctly predict the diagnostic group of the training sample (26 medicated patients and 12 controls, with 89% sensitivity and 75% specificity (p<0.001. The 10-gene predictor was further explored via testing on an independent cohort consisting of three pairs of monozygotic twins discordant for BPD, plus the original enrichment sample cohort (the three never-medicated BPD patients and 13 matched control subjects, and a sample of experimental replicates (n=34. 83% of the independent test sample was correctly predicted, with a sensitivity of 67% and specificity of 100% (although this result did not reach statistical significance. Additionally, 88% of sample diagnostic classes were classified correctly for both the enrichment (p=0.015 and the replicate samples (p<0.001. We have developed a peripheral gene expression biomarker profile, that can classify healthy controls from patients with BPD receiving antipsychotic or mood stabilizing medication, which has both high sensitivity and specificity

    Identification of risk factors within precursor syndromes, such as depression, anxiety or substance use disorders (SUD), might help to pinpoint high-risk stages where preventive interventions for Bipolar Disorder (BD) could be evaluated. We examined baseline demographic, clinical, quality of life, and temperament measures along with risk clusters among 52 young people seeking help for depression, anxiety or SUDs without psychosis or BD. The risk clusters included Bipolar At-Risk (BAR) and the Bipolarity Index as measures of bipolarity and the Ultra-High Risk assessment for psychosis. The participants were followed up for 12 months to identify conversion to BD. Those who converted and did not convert to BD were compared using Chi-Square and Mann Whitney U tests. The sample was predominantly female (85%) and a majority had prior treatment (64%). Four participants converted to BD over the 1-year follow up period. Having an alcohol use disorder at baseline (75% vs 8%, χ(2)=14.1, pdepressive symptoms and cannabis use had high effects sizes of association with BD outcomes, without statistical significance. The small number of conversions limited the power of the study to identify associations with risk factors that have previously been reported to predict BD. However, subthreshold affective symptoms and SUDs might predict the onset of BD among help-seeking young people with high-prevalence disorders. Copyright © 2015 Elsevier B.V. All rights reserved.

    The hypomanic personality style is a risk factor for bipolar spectrum disorders and shares many cognitive and affective features with the bipolar spectrum. Schema theory may serve as a unifying theory that would explain many of these features. This study is an exploratory investigation of Early Maladaptive Schemas (EMSs) in association with the hypomanic personality and bipolar spectrum risk. A sample of 966 participants completed the Young Schema Questionnaire, the Hypomanic Personality Scale and the Patient Health Questionnaire. Associations were investigated using univariate and multivariate analyses. Participants deemed at risk of developing a bipolar disorder (N=107) were compared to low-risk controls (N=681). The Entitlement/Grandiosity and Insufficient Self-Control/Self-Discipline positively predicted the risk of developing a bipolar disorder, while Emotional Inhibition negatively predicted risk. High-risk participants demonstrated higher mean scores on all EMSs except Emotional Inhibition. These three EMSs, combined with Vulnerability to Harm or Illness, significantly predicted group membership. A bipolar spectrum EMS profile was identified, consisting of Entitlement/Grandiosity, Insufficient Self-Control/Self-Discipline and the absence of Emotional Inhibition. These EMSs are highly consistent with characteristics of the bipolar spectrum. This study supports the application of schema theory to the hypomanic personality and bipolar spectrum. Future research should explore the possible interaction between EMSs, life events and affective symptoms and the applicability of schema therapy to the bipolar spectrum. Crown Copyright © 2011.

    The objective of this study was to identify molecular alterations in the human blood serum related to bipolar disorder, using nuclear magnetic resonance (NMR) spectroscopy and chemometrics. Metabolomic profiling, employing (1)H-NMR, (1)H-NMR T2-edited, and 2D-NMR spectroscopy and chemometrics of human blood serum samples from patients with bipolar disorder (n = 26) compared with healthy volunteers (n = 50) was performed. The investigated groups presented distinct metabolic profiles, in which the main differential metabolites found in the serum sample of bipolar disorder patients compared with those from controls were lipids, lipid metabolism-related molecules (choline, myo-inositol), and some amino acids (N-acetyl-L-phenyl alanine, N-acetyl-L-aspartyl-L-glutamic acid, L-glutamine). In addition, amygdalin, α-ketoglutaric acid, and lipoamide, among other compounds, were also present or were significantly altered in the serum of bipolar disorder patients. The data presented herein suggest that some of these metabolites differentially distributed between the groups studied may be directly related to the bipolar disorder pathophysiology. The strategy employed here showed significant potential for exploring pathophysiological features and molecular pathways involved in bipolar disorder. Thus, our findings may contribute to pave the way for future studies aiming at identifying important potential biomarkers for bipolar disorder diagnosis or progression follow-up.

  1. Linkage analysis of bipolar illness with X-chromosome DNA markers: A susceptibility gene in Xq27-q28 cannot be excluded

    Transmission studies have supported the presence of a susceptibility gene for bipolar (BP) illness on the X-chromosome. Initial linkage studies with color blindness (CB), glucose-6-phosphate dehydrogenase (G6PD) deficiency, and the blood coagulation factor IX (F9) have suggested that a gene for BP illness is located in the Xq27-q28 region. We tested linkage with several DNA markers located in Xq27-q28 in 2 families, MAD3 and MAD4, that previously were linked to F9, and 7 newly ascertained families of BP probands. Linkage was also examined with the gene encoding the {alpha}3 subunit of the gamma-amino butyric acid receptor (GABRA3), a candidate gene for BP illness located in this region. The genetic data were analyzed with the LOD score method using age-dependent penetrance of an autosomal dominant disease gene and narrow and broad clinical models. In MAD3 and MAD4 the multipoint LOD score data suggested a localization of a BPI gene again near F9. In the 7 new families the overall linkage data excluded the Xq27-q28 region. However, if the families were grouped according to their proband`s phenotype BPI or BPII, a susceptibility gene for BPI disorder at the DXS52-F8 cluster could not be excluded. 48 refs., 2 figs., 3 tabs.

    Full Text Available Background and Aims: Heat-related illness (HRI due to high ambient temperatures is a common feature during the Indian summer. HRI often results in Intensive Care Unit (ICU admissions and are associated with significant morbidity and mortality. However, published report on the effects of HRI among the Indian population is lacking. This study was undertaken to identify the profile of patients admitted to ICU with clinical features of HRI and study their clinical outcomes. Methods: This was a retrospective case series of patients admitted with features of HRI during the summer of 2012 in our multidisciplinary ICU. Data on demographics, co-morbid illness, admission severity of illness (Acute Physiology and Chronic Health Evaluation II [APACHE II], organ failure scores (Sequential Organ Failure Assessment [SOFA] and neuroimaging studies were collected. Outcome data studied included mortality, ICU length of stay (LOS, ventilator days and hospital LOS. Statistical analysis was performed using Student′s t-test, Chi-square test and multivariate analysis. Results: Twenty-six patients met the diagnostic criteria for HRI. Fifteen were males. The mean age was 53.12 ΁ 18.6 years. Mean APACHE II score was 19.6 ΁ 7.7 and mean SOFA score was 7.5 ΁ 2.6. The common presenting symptoms were fever with neurological impairment (100% and gastrointestinal symptoms (30%. Major organ systems involvement include neurological (100%, renal (57%, hepatic (34% and coagulation abnormalities (26%. Most common metabolic abnormality noted was hyponatraemia (73%. Magnetic resonance imaging findings suggestive of heat stroke were seen in 5 of 26 patients. Mortality rate was 34%. 8 of 17 survivors had residual neurological impairment. Conclusion: HRI carries a high mortality and significant neurological morbidity.

    As with physical conditions, bipolar disorder is likely to be impacted by diet and nutrition. Patients with bipolar disorder have been noted to have relatively unhealthy diets, which may in part be the reason they also have an elevated risk of metabolic syndrome and obesity. An improvement in the quality of the diet should improve a bipolar patient's overall health risk profile, but it may also improve their psychiatric outcomes. New insights into biological dysfunctions that may be present in bipolar disorder have presented new theoretic frameworks for understanding the relationship between diet and bipolar disorder.

    Full Text Available Jodi M Gonzalez1, Peter M Thompson1, Troy A Moore1,21University of Texas Health Science Center, San Antonio, TX, USA; 2South Texas Veterans Health Care System, TX, USAObjective: Asenapine is approved for acute manic and mixed states in bipolar disorder. The objective is to review the efficacy of asenapine in bipolar disorder, with a particular focus on acceptability and adherence to treatment.Methods: Five clinical trials were conducted in bipolar disorder manic or mixed states: two 3-week trials (n = 976 comparing asenapine to placebo, a 9-week extension (n = 504, and a 40-week extension (n = 107. One trial was conducted comparing asenapine to placebo (n = 326 as adjunctive therapy for subjects with an incomplete response to lithium or valproate. All trials were conducted in the USA and internationally.Results: Asenapine was found to be efficacious for manic and mixed states in bipolar disorder compared with placebo control, and compares equally well to olanzapine on efficacy measures after 3 weeks of treatment. Asenapine was not found to be efficacious for depression symptoms. Common asenapine side effects in the 40-week extension trial were sedation, insomnia, and dizziness, and 31% reported clinically significant weight gain, compared with 55% reporting clinically significant weight gain with olanzapine. Additionally, 18% had clinically significant changes in fasting blood glucose levels compared to 22% of those on olanzapine. In terms of patient acceptability, one concern may be sublingual administration requiring no liquids or food for 10 minutes after dosing and a twice-daily regimen. Suggestions about addressing barriers to adherence and acceptability are provided.Conclusion: Asenapine is a promising new medication in bipolar disorder. Asenapine in the long-term has a more favorable weight gain profile compared to olanzapine. No benefit was seen for depression symptoms, a major patient-reported concern. Some side effects do not remit

    Minor physical anomalies (MPAs) are external markers of abnormal brain development, so the more common appearence of these signs among bipolar I and bipolar II patients can confirm the possibility of a neurodevelopmental deficit in these illnesses. The aim of the present study was to investigate the rate and topological profile of minor physical anomalies in patients with bipolar I and - first in literature - with bipolar II disorders compared to matched healthy control subjects. Using a list of 57 minor physical anomalies (the Méhes Scale), 30 bipolar I and 30 bipolar II patients, while as a comparison 30 matched healthy control subjects were examined. Significant differences were detected between the three groups comparing the total number of minor physical anomalies, minor malformations and phenogenetic variants and in the cases of the ear and the mouth regions. The individual analyses of the 57 minor physical anomalies by simultaneous comparison of the three groups showed, that in the cases of furrowed tongue and high arched palate were significant differences between the three groups. The results can promote the concept, that a neurodevelopmental deficit may play a role in the etiology of both bipolar I and bipolar II disorders.

    The aim was to investigate the personality profile of bipolar disorder I and II, and healthy controls, and to study whether personality influences the course of bipolar disorder. One hundred ten patients with bipolar disorder I, 85 patients with bipolar disorder II, and 86 healthy individuals had their personality profile assessed using the Swedish universities Scales of Personality (SSP), an instrument developed to explore personality-related vulnerabilities and correlates of psychiatric disorders. Patients were followed prospectively for 2 years. To assess the impact of Neuroticism, Aggressiveness, and Disinhibition on illness course, we performed logistic regressions with the outcome variables mood episodes (depressive, hypo/manic, mixed), suicide attempts, violence, and the number of sick leave days. Bipolar disorder I and II demonstrated higher global measures of Neuroticism, Aggressiveness, and Disinhibition as compared with healthy controls. A third of the patients scored ≥1 SD above the population-based normative mean on the global neuroticism measure. The two subtypes of bipolar disorder were, however, undistinguishable on all of the personality traits. In the unadjusted model, higher neuroticism at baseline predicted future depressive episodes and suicide attempts/violent behavior, but this association disappeared when adjusting for baseline depressive symptoms as assessed with MADRS. A significant minority of the patients scored ≥1 SD above the population mean on the global measures of Neuroticism, Aggressiveness and Disinhibition; scores this high are usually evident clinically. Yet, the personality profile does not seem to have prognostic value over a 2-year period.

    Bipolar Disorder (BD) has been conceptualized as both a cyclic and a progressive disorder. Mechanisms involved in neuroprogression in BD remain largely unknown although several non-mutually exclusive models have been proposed as explanatory frameworks. In the present paper, we propose that the pathophysiological changes observed in BD (e.g. brain structural alterations, cognitive deficits, oxidative stress imbalance, amyloid metabolism, immunological deregulation, immunosenescence, neurotrophic deficiencies and telomere shortening) converge on a model of accelerated aging (AA). Aging can be understood as a multidimensional process involving physical, neuropsychological, and social changes, which can be highly variable between individuals. Determinants of successful aging (e.g environmental and genetic factors), may also confer differential vulnerability to components of BD pathophysiology and contribute to the clinical presentation of BD. Herein we discuss how the understanding of aging and senescence can contribute to the search for new and promising molecular targets to explain and ameliorate neuroprogression in BD. We also present the strengths and limitations of this concept.

    Bipolar disorder (BD) is a recurrent and disabling illness, characterized by periods of depression and mania. The history of the illness differs widely between patients, with episode frequency emerging as a strong predictor of poor illness outcome. Lithium salts are the first-choice long-term mood-stabilizing therapy, but not all patients respond equally to the treatment. Evidence suggests that alterations in glutamatergic systems may contribute to the pathophysiology of depression. Moreover, glutamate signaling is involved in brain development and synaptic plasticity, both of which are modified in individuals affected by BD, and has been implicated in the etiology of the disorder. The inactivation of glutamate is handled by a series of molecular glutamate transporters (excitatory amino acid transporters [EAATs]), among which EAAT2/SLC1A2 is responsible for up to 95% of extracellular glutamate clearance. A functional single-nucleotide polymorphism at -181 bp from the transcription start site of the SLC1A2 gene has been described. This T-to-G (DNA forward strand) polymorphism, commonly known as SLC1A2 -181A>C, affects transporter expression, with the variant G allele inducing a 30% reduction in promoter activity compared with the T allele. The aims of the study were to investigate if factors affecting glutamate function, such as SLC1A2 -181A>C (rs4354668), could affect recurrence of illness in BD, and if they interact with lithium salt treatment. We performed an observational study in our university hospital in Milan. We enrolled 110 subjects (76 females, 34 males) affected by BD type I. The exclusion criteria were other diagnoses on Axis I, mental retardation on Axis II, a history of epilepsy, and major medical and neurologic disorders. Fifty-four patients had been treated with lithium salts for more than 6 months. Patients were genotyped for SLC1A2 -181A>C by polymerase chain reaction-restriction fragment length polymorphism, and the influence of genotype on BD

    Full Text Available BACKGROUND: Dengue is an important medical problem, with symptoms ranging from mild dengue fever to severe forms of the disease, where vascular leakage leads to hypovolemic shock. Cytokines have been implicated to play a role in the progression of severe dengue disease; however, their profile in dengue patients and the synergy that leads to continued plasma leakage is not clearly understood. Herein, we investigated the cytokine kinetics and profiles of dengue patients at different phases of illness to further understand the role of cytokines in dengue disease. METHODS AND FINDINGS: Circulating levels of 29 different types of cytokines were assessed by bead-based ELISA method in dengue patients at the 3 different phases of illness. The association between significant changes in the levels of cytokines and clinical parameters were analyzed. At the febrile phase, IP-10 was significant in dengue patients with and without warning signs. However, MIP-1β was found to be significant in only patients with warning signs at this phase. IP-10 was also significant in both with and without warning signs patients during defervescence. At this phase, MIP-1β and G-CSF were significant in patients without warning signs, whereas MCP-1 was noted to be elevated significantly in patients with warning signs. Significant correlations between the levels of VEGF, RANTES, IL-7, IL-12, PDGF and IL-5 with platelets; VEGF with lymphocytes and neutrophils; G-CSF and IP-10 with atypical lymphocytes and various other cytokines with the liver enzymes were observed in this study. CONCLUSIONS: The cytokine profile patterns discovered between the different phases of illness indicate an essential role in dengue pathogenesis and with further studies may serve as predictive markers for progression to dengue with warning signs.

    Disturbances of the hypothalamic-pituitary-adrenal axis have been implicated in the pathophysiology of bipolar disorder (BD) and major depressive disorder (MDD). To examine this further, we carried out proteomic profiling of post-mortem pituitaries from 13 BD and 14 MDD patients, in comparison to 15 controls. Liquid chromatography-mass spectrometry (LC-MS(E)) analysis showed that BD patients had significantly increased levels of the major pituitary hormones pro-opiomelanocortin (POMC) and galanin. BD patients also showed changes in proteins associated with gene transcription, stress response, lipid metabolism and growth signalling. In contrast, LC-MS(E) profiling revealed that MDD patients had significantly decreased levels of the prohormone-converting enzyme carboxypeptidease E and follow-up enzymatic analysis showed decreased activity of prolyl-oligopeptidase convertase. This suggested that altered prohormone processing may occur in pituitaries of MDD patients. In addition, MDD patients had significant changes in proteins involved in intracellular transport and cytoskeletal signalling. Finally, we carried out selective reaction monitoring (SRM) mass spectrometry profiling for validation of protein changes in key biological pathways. This confirmed increased POMC levels in BD patients with no change in the levels of this prohormone in MDD. This study demonstrates that proteomic profiling analysis of the pituitary can lead to new insights into the pathophysiology of BD and MDD. Also, given that the pituitary directly releases a variety of bioactive molecules into the bloodstream, many of the proteins identified here could serve as focal points in the search for peripheral biomarkers in clinical or drug treatment studies of BD and MDD patients.

    Full Text Available Background Record based review of the 2009 H1N1 Influenza pandemic suggests that pregnant women are at higher risk for hospitalization and death due to H1N1 Influenza. Aims To study the clinical profile and outcome of critically ill pregnant females admitted in intensive care unit (ICU with real-time recombinant polymerase chain reaction (rRT-PCR proven positive H1N1 cases. Methods A retrospective record-review based study was conducted at Sir SayajiRao General Hospital (SSGH and Medical College, Vadodara on data of confirmed rRT-PCR H1N1 pregnant females admitted during the pandemics of 2010and 2015. Demographics, clinical profile and laboratory investigations were recorded and outcomes (survived or expired were analysed. Results There were a total of 20 H1N1 positive pregnant females requiring ICU admission. With equal demographic distribution among rural and urban population, cough and fever were the most common presenting complaints. 65 per cent were in third trimester, the subgroup which also had the highest mortality. Mean days from onset until presentation was 5.05 days. 12 (60 per cent patients’ required invasive mode of ventilation and all died. Average hospital stay was 7 days. Foetus had favourable outcome in patients who recovered from H1N1 acute illness. Conclusion Pregnant females in our study had 60 per cent mortality. Thus, awareness, early diagnosis and treatment should be provided to them. Guidelines, policy changes and government protocols are required specifically for pregnant females with H1N1 Influenza A infection. Our study was an observational study and comparisons with non-pregnant females were not done, conclusions applicable to entire pregnant population was not derived.

    Many studies suggest the presence of aberrations in cellular metabolism in bipolar disorder. We studied the metabolome in bipolar disorder to gain insight into cellular pathways that may be dysregulated in bipolar disorder and to discover evidence of novel biomarkers. We measured polar and nonpolar metabolites in fibroblasts from subjects with bipolar I disorder and matched healthy control subjects, under normal conditions and with two physiologic perturbations: low-glucose media and exposure to the stress-mediating hormone dexamethasone. Metabolites that were significantly different between bipolar and control subjects showed distinct separation by principal components analysis methods. The most statistically significant findings were observed in the perturbation experiments. The metabolite with the lowest p value in both the low-glucose and dexamethasone experiments was α-aminoadipate, whose intracellular level was consistently lower in bipolar subjects. Our study implicates α-aminoadipate as a possible biomarker in bipolar disorder that manifests under cellular stress. This is an intriguing finding given the known role of α-aminoadipate in the modulation of kynurenic acid in the brain, especially as abnormal kynurenic acid levels have been implicated in bipolar disorder.

    1992-01-01

    Recent advances in low-temperature epitaxial growth of strained silicon-germanium alloys on silicon substrates allow bandgap engineering in silicon-based devices, with profound consequences for device design. In this thesis the improved control by Rapid Thermal Chemical Vapor Deposition of the vertical profile of a Si/Si_{1-x}Ge _{x}/Si heterojunction bipolar transistor (HBT) is used to study the effect of the shape of the conduction band in the base on device performance. Near-ideal base currents in Si/Si_ {1-x}Ge_{x}/Si HBT's, limited by hole injection into the emitter, are achieved using a non-ultra-high vacuum (UHV) technique for the first time, proving that high-lifetime Si_{1-x}Ge _{x} material can be fabricated using processes compatible with standard silicon technology. Graded-base Si/Si_{1-x}Ge_{x} /Si HBT's are fabricated in a non-UHV epitaxial technology for the first time, and their electrical characteristics are modeled analytically. The formation of parasitic potential barriers for electrons in the base of HBT's resulting from base dopant outdiffusion or non-abrupt interfaces is studied, together with the concurrent degradation of the electrical performance of the devices. This deleterious effect is especially severe in devices with narrow, heavily doped bases fabricated in an integrated circuit (IC) process because of the thermal budget employed. To alleviate this problem, intrinsic Si_{1-x}Ge_{x}^acer layers can be inserted on both sides of the base to greatly improve device performance. The tradeoff between the common-emitter current gain beta and the Early voltage V_{A} (output resistance) in heterojunction bipolar transistors is investigated for the first time. This tradeoff is important for analog application of HBT's, and it is shown that thin, narrow -gap layers in the base close to the base-collector junction reduce the Early effect dramatically leading to a high Early voltage. It is further demonstrated that even small amounts of dopant

    Full Text Available Patients with bipolar disorder spend more time in a depressed than manic state, even with individualized treatment. To date, bipolar depression is often misdiagnosed and ineffectively managed both for acute episodes and residual symptoms. This review attempts to summarize the current status of available treatment strategies in the treatment of bipolar depression. For acute and prophylactic treatment, a substantial body of evidence supports the antidepressive efficacy of lithium for bipolar disorders and its antisuicidal effects. Among numerous anticonvulsants with mood-stabilizing properties, valproate and lamotrigine could be first-line options for bipolar depression. Due to receptor profile, mood-stabilizing properties of second-generation antipsychotics have been explored, and up to date, quetiapine and olanzapine appear to be a reasonable option for bipolar depression. The usefulness of antidepressants in bipolar depression is still controversial. Current guidelines generally recommend the cautious antidepressant use in combination with mood stabilizers to reduce the risk of mood elevation or cycle acceleration. Results from clinical trials on psychosocial intervention are promising, especially when integrated with pharmacotherapy. Most patients with bipolar depression need individualized and combined treatment, although the published evidence on this type of treatment strategy is limited. Future studies on the utility of currently available agents and modalities including psychosocial intervention are required.

Over the last decade all atypical drugs except for clozapine have received a Food and Drug Administration (FDA bipolar indication. In October 2008, the FDA approved quetiapine XR monotherapy for the treatment of acute depressive episodes of bipolar disorder and acute manic or mixed episodes in bipolar I disorder based on two placebo-control trials. Quetiapine was also approved as adjunct therapy with lithium and divalproex for the treatment of acute manic or mixed episodes as well as maintenance of bipolar I disorder. In contrast to immediate release quetiapine which may require a twice-daily regimen, the XR formulation is intended for once-daily administration. This drug profile of quetiapine XR will address chemistry, pharmacodynamics, pharmacokinetics, metabolism, safety and tolerability and clinical trials in bipolar disorder.Keywords: quetiapine XR, bipolar disorder

    2009-06-01

    In clinical practice, overt aggressive behaviour is frequently observed in patients diagnosed with bipolar disorder. It can be dangerous and complicates patient care. Nevertheless, it has not been adequately studied as a phenomenon that is separate from other symptoms such as agitation. The aim of this review is to provide information on the prevalence, clinical context, and clinical management of aggression in patients with bipolar disorder. MEDLINE and PsycInfo data bases were searched for articles published between 1966 and November 2008 using the combination of key words 'aggression' or 'violence' with 'bipolar disorder'. For the treatment searches, generic names of mood stabilisers and antipsychotics were used in combination with key words 'bipolar disorder' and 'aggression'. No language constraint was applied. Articles dealing with children and adolescents were not included. Acutely ill hospitalised bipolar patients have a higher risk for aggression than other inpatients. In a population survey, the prevalence of aggressive behaviour after age 15 years was 0.66% in persons without lifetime psychiatric disorder, but 25.34% in bipolar I disorder. Comorbidity with personality disorders and substance use disorders is frequent, and it elevates the risk of aggression in bipolar patients. Impulsive aggression appears to be the most frequent subtype observed in bipolar patients. Clinical management of aggression combines pharmacological and non-pharmacological approaches. A major problem with the evidence is that aggression is frequently reported only as one of the items contributing to the total score on a scale or a subscale. This makes it impossible to ascertain specifically aggressive behaviour. Large controlled head-to-head randomised controlled studies comparing treatments for aggressive behaviour in bipolar disorder are not yet available. There is some evidence favouring divalproex, but it is not particularly strong .We do not know if there are any efficacy

    Children and adolescents with bipolar disorder may have depression as the presenting mood state. It is important for clinicians to distinguish between unipolar and bipolar depression in youth. Depressive episodes are common during the course of bipolar illness in children and adolescents. Evidence-based treatments are needed to guide clinicians' treatment decisions for youth with bipolar depression. This article reviews the prevalence, diagnosis, course, and treatment of bipolar depression in youth, and emphasizes the need for large, controlled treatment studies in the pediatric population.

    Background: Surveillance of antimicrobial resistance is vital to guiding empirical treatment of infections. Collating and reporting routine data on clinical isolate testing may offer more timely information about resistance patterns than traditional surveillance network methods. Methods: Using routine microbiology testing data collected from the Bacteremia Antibiotic Length Actually Needed for Clinical Effectiveness retrospective cohort study, we conducted a descriptive secondary analysis among critically ill patients in whom bloodstream infections had been diagnosed in 14 intensive care units (ICUs) in Canada. The participating sites were located within tertiary care teaching hospitals and represented 6 provinces and 10 cities. More than 80% of the study population was accrued from 2011-2013. We assessed the epidemiologic features of the infections and corresponding antimicrobial susceptibility profiles. Susceptibility testing was done according to Clinical Laboratory Standards Institute guidelines at accredited laboratories. Results: A total of 1416 pathogens were isolated from 1202 patients. The most common organisms were Escherichia coli (217 isolates [15.3%]), Staphylococcus aureus (175 [12.4%]), coagulase-negative staphylococci (117 [8.3%]), Klebsiella pneumoniae (86 [6.1%]) and Streptococcus pneumoniae (85 [6.0%]). The contribution of individual pathogens varied by site. For 13 ICUs, gram-negative susceptibility rates were high for carbapenems (95.4%), tobramycin (91.2%) and piperacillin-tazobactam (90.0%); however, the proportion of specimens susceptible to these agents ranged from 75.0%-100%, 66.7%-100% and 75.0%-100%, respectively, across sites. Fewer gram-negative bacteria were susceptible to fluoroquinolones (84.5% [range 64.1%-97.2%]). A total of 145 patients (12.1%) had infections caused by highly resistant microorganisms, with significant intersite variation (range 2.6%-24.0%, χ2 = 57.50, p < 0.001). Interpretation: We assessed the epidemiologic

    Full Text Available Abstract Background Suicide is an important and potentially preventable consequence of serious mental disorders of unknown etiology. Gene expression profiling technology provides an unbiased approach to identifying candidate genes for mental disorders. Microarray studies with post-mortem prefrontal cortex (Brodmann's Area 46/10 tissue require larger sample sizes. This study poses the question: to what extent are differentially expressed genes for suicide a diagnostic specific set of genes (bipolar disorder vs. schizophrenia vs. a shared common pathway? Results In a reanalysis of a large set of Affymetrix Human Genome U133A microarray data, gene expression levels were compared between suicide completers vs. non-suicide groups within a diagnostic group, namely Bipolar disorder (N = 45; 22 suicide completers; 23 non-suicide or Schizophrenia (N = 45; 10 suicide completers ; 35 non-suicide. Among bipolar samples, 13 genes were found and among schizophrenia samples, 70 genes were found as differentially expressed. Two genes, PLSCR4 (phospholipid scramblase 4 and EMX2 (empty spiracles homolog 2 (Drosophila were differentially expressed in suicide groups of both diagnostic groups by microarray analysis. By qRT-PCR, PLSCR4 and EMX2 were significantly down-regulated in the schizophrenia suicide completers, but could not be confirmed in bipolar disorder. Conclusion This molecular level analysis suggests that diagnostic specific genes predominate to shared genes in common among suicide vs. non-suicide groups. These differentially expressed, candidate genes are neural correlates of suicide, not necessarily causal. While suicide is a complex endpoint with many pathways, these candidate genes provide entry points for future studies of molecular mechanisms and genetic association studies to test causality.

    Data from the imaging literature have led to suggestions that permanent structural brain changes may be associated with bipolar disorder. Individuals diagnosed with bipolar disorder display deficits on a range of neuropsychological tasks in both the acute and euthymic phases of illness, and correlations between experienced number of affective episodes and task performance are commonly reported. These findings have renewed interest in the neuropsychological profile of individuals with bipolar disorder, with deficits of attention, learning and memory, and executive function, asserted to be present. This paper critically reviews five different potential causes of neurocognitive dysfunction in bipolar disorder: (i) iatrogenic, (ii) acute functional changes associated with depression or mania, (iii) permanent structural lesions of a neurodegenerative origin, (iv) permanent structural lesions that are neurodevelopmental in origin, and (v) permanent functional changes that are most likely genetic in origin. Although the potential cognitive effects of residual symptomatology and long-term medication use cannot be entirely excluded, we conclude that functional changes associated with genetically driven population variation in critical neural networks underpin both the neurocognitive and affective symptoms of bipolar disorder. The philosophical implications of this conclusion for neuropsychology are briefly discussed.

    Full Text Available Rubber is one of the important commodities in the world. Globally, workers are facing so many problems of hazards that produce by rubber process. In Indonesia, there are several data of occupational problems such as respiratory diseases, muscle and skeletal diseases, gastrointestinal diseases, diseases of the teeth and oral cavity, skin diseases and skin tissue. In Iranian rubber factory, Iran, workers had suffered from some kind of musculoskeletal symptoms. Stomach and liver cancers in workers are having in Shanghai tire factory. In addition, Germany has cancer problem of their workers who work in rubber factory. Most of the rubber process in the factory can cause some hazards of the workers. In unloading area and area that operator is taking the dirt manually, workers are facing ergonomic problems. The possible control is reduce weight of load, team lift the object with two or more workers and Use mechanical assist. Machine safeguarding is essential for protecting from Cutting process that can make workers amputation organs such as hands, and fingers. In bale process, the workers need to cut raw rubber into bale in bale cutting. Furthermore, workers are facing with amputation problem. To manage that, It must be designed as a standard which has interlocking guards to prevent access to the cutting area. When wrapped using plastic, workers use a heated iron and sticked in plastic so that it blends neatly. The risks are fingers can cut accidently and then the workers also get contamination from polyvinyl chloride (PVC. The possible preventions are use an automatic plastic wrapping machine with palletized product sitting on a turntable and respirator. Another problem is contact dermatitis that has been reported frequently among rubber workers. The prevention for that problem is using Gloves. The aim of researcher is to provide the profile of occupational injuries and illnesses, potential hazards in rubber factory to prevent the workers.

    Recent research has documented the unusually high rates of incarcerated women’s serious mental illness (SMI) and substance use disorders (SUD). Complicating these high rates is the high comorbidity of SMI with SUD and trauma histories. Yet, incarcerated women have significantly less access to treatment and health services while incarcerated than men. We used data from a multi-site, multi-method project funded by the Bureau of Justice Assistance (2011–2012) to determine the risk profile of wom...

    Control of pain management is an important up-stream process in fibromyalgia (FM) mechanisms. To investigate whether adapted physical activity (APA) could change the illness perception in relation to the FM personality profile. Thirty-seven women with FM allocated randomly: 19 treatment group (TG) and 18 control group (CG). Interventions: exercises program included ten sessions, two times for week for one hour each and observation for CG. Scales: Illness Perception Questionnaire-revisited (IPQ-r) for the mental representation of the disease, Minnesota Multiphasic Personality Inventory profiles (MMPI-2) for personality tool and Fibromyalgia Impact Questionnaire (FIQ) for function, impact and symptoms. Outcome assessments were performed before rehabilitation treatment (T0) than at the end (T1), and a follow-up 12 weeks after treatment (T2). APA was efficacy to improve FIQ values in TG at T1 and T2 test days (P = 0.014). Changes in IPQ-R values in T2 were not significant. All patients presented a baseline T-score≥65 in at least one of the basic and content MMPI-2 scales (Hy, D, Hs and Hea and Anx). APA was efficacy in FM, but further research to differentiate between illness experience rather than focus ona strict personality profile are necessary.

    2011-03-01

    Provide an overview of how bipolar disorder affects cognitive function in patients. MEDLINE and PsycInfo data bases were searched for articles indexed by the combinations of MESH term or key word "bipolar disorder" with the following terms: "cognition", "memory", "neuropsychology", "neuropsychological tests", "lithium", "anticonvulsants", "antipsychotics", and "schizophrenia". Constraints limiting time period of publications or their language were not applied. Reference lists of publications identified by these procedures were hand-searched for additional relevant citations. There is evidence of stable and lasting cognitive impairment in all phases of bipolar disorder, including the remission phase, particularly in the following domains: sustained attention, memory and executive functions. But research on the cognitive functions has yielded inconsistent results over recent years. There is a growing need for clarification regarding the magnitude, clinical relevance and confounding variables of cognitive impairment in bipolar patients. The impact of bipolar illness on cognition can be influenced by age of onset, pharmacological treatments, individual response, familial risk factors, and clinical features. In addition to the mood state, cognitive performance in bipolar patients is influenced by seasonality. Previous optimistic assumptions about the prognosis of bipolar disorder were based on the success of the control of mood symptoms by pharmacotherapy. However, it is now clear that the "remitted" euthymic bipolar patients have distinct impairments of executive function, verbal memory, psychomotor speed, and sustained attention. Mood stabilizers and atypical antipsychotics may reduce cognitive deficits in certain domains and may have a positive effect on quality of life and social functioning.

    Psychological stress is a risk factor as well as a consequence of central serous chorioretinopathy (CSC). Impulsiveness, overachievement, emotional instability, and hard-driving competitiveness have been discussed as personality features in CSC patients. We investigated 57 consecutive CSC patients and 57 age- and gender-matched controls by means of the Symptom Checklist 90-R and the Temperament and Character Inventory. Somatic risk factors, illness characteristics, subjective assessment of severity of illness, and illness-related stress in different areas of life (work, private life) were evaluated. CSC patients showed significantly higher emotional distress as measured by the Global Severity Index. The CSC personality was characterized by lower scoring on the character dimension cooperativeness and the temperament dimension reward dependence. Cooperativeness as well as subjective assessment of severity of CSC has been recognized as significant predictors of illness-related work stress accounting for 30% of variance. Implicating competitiveness, hostility and emotional detachment, lower level of cooperativeness, and reward dependence support the existence of specific aspects of type A behaviour in CSC patients. Low perceived social support and loss of control may explain the significant contribution of this personality dimension to illness-related work stress. Treatment of CSC should thus incorporate psychoeducation about factors contributing to illness-related stress.

    Identify and describe population groups with greater risk and morbidity profiles for type II diabetes, hypertension, and tobacco-related illnesses. A cross-sectional study was carried out of 840 families under the care of 12 family doctors and nurses in Havana, Cuba. A model-based cluster analysis was used to identify subpopulations with specific morbidity and risk profiles. Key indicators of the subpopulations were compared. A subpopulation with a high disease burden and a particular risk profile was identified and described. The determining factor in defining this group is the subjective perception of their economic situation. The families in this group have the highest household density of diabetes, hypertension, and tobacco-related illnesses and are distributed among all the facilities visited. On average, the subpopulation consisted of smaller families and have between two and three years less schooling, a more negative perception of their economic situation, and an older average age, when compared to the study group as a whole. Subpopulations were identified with higher proportions of the disease burden and with particular risk profiles. These subpopulations exhibit certain features consistent with trends in the social structure of Cuban families that have been evolving over the past two decades.

    Cognitive impairment among seriously mentally ill offenders has implications for legal matters (e.g., competency to stand trial), as well as clinical treatment and care. Thus, being able to identify potential cognitive concerns early in the adjudication process can be important when deciding on further interventions. In this study, we examined the validity scales of the Personality Assessment Inventory (PAI), scores on the Wechsler Adult Intelligence Scale-IV (WAIS-IV), and competency findings in male inmates (n=61) diagnosed with a serious mental illness. Lower scores on the WAIS-IV significantly (p=0.001) predicted invalid, versus valid, PAI profiles, with working memory impairment being the most significant (p=0.004) predictor of an invalid profile. Ancillary analyses on a smaller sample (n=18) indicate that those with invalid PAI profiles were more likely to be deemed legally incompetent (p=0.03). These findings suggest that the PAI validity scales may be informative in detecting cognitive concerns and help clinicians make determinations about competency restoration and treatment.

    2011-12-01

    Several recent studies have shown that bipolar disorder is underdiagnosed in patients with major depression. Missing the diagnosis of a bipolar disorder may have serious and even occasionally fatal consequences for a patient with the disease. Moreover misdiagnosis may lead to inappropriate treatment and therefore contribute to worsening medical and functional prognosis. Although there are no pathognomonic characteristics of bipolar depression compared to unipolar depression, evidence-based findings suggest that some features may be indicative of bipolarity, in patients with depression. These features are related to clinical picture of depressive state, course of episode and illness, response to treatment, family history, comorbid conditions, as well as demographic and temperamental characteristics. Based on such features, some authors have proposed operationalized criteria or a diagnostic specific for bipolarity, to identify bipolar depression. Screening instruments may also be used, to facilitate early recognition. Validation studies of these diagnostic features and instruments are underway.

    Full Text Available O transtorno bipolar é uma condição médica complexa e até o momento não há um tratamento único comprovadamente eficaz no controle de todos aspectos da doença. Foram revisadas a literatura disponível sobre o uso de anticonvulsivantes (valproato, carbamazepina, oxcarbazepina, lamotrigina, gabapentina, topiramato, clonazepam e antipsicóticos atípicos (clozapina, risperidona, olanzapina, quetiapina, ziprasidona e aripiprazole no tratamento agudo e profilático do transtorno bipolar. Existe um acúmulo de evidências acerca da eficácia do lítio na profilaxia e de ser melhor no tratamento da mania aguda do que nos episódios depressivos. Outros dados indicam que a carbamazepina e o valproato são eficazes na mania aguda. A lamotrigina parece reduzir ciclagem e ser eficaz em episódios depressivos. Baseado nas informações disponíveis, as evidências apontam a olanzapina como o antipsicótico atípico mais apropriado no tratamento de pacientes bipolares em mania, embora existam estudos sugerindo a eficácia da risperidona, aripiprazol e da clozapina. Resultados preliminares avaliando a eficácia de ziprasidona e quetiapina no transtorno bipolar ainda são bastante limitadas.

    The effects of two different base doping profiles on the current gain and cut-off frequency for all levels of current injection have been studied for NPN Si/SiGe/Si double heterojunction bipolar transistors (SiGe DHBTs). The two-dimensional simulation results for a SiGe DHBT with uniform base doping and a fixed base Gummel number are compared with a non-uniform base doping profile SiGe drift-DHBT device. The study explains the performance of SiGe HBTs at different injection levels by analysing the electron and hole mobility, drift velocity, electric field, junction capacitances and intrinsic and extrinsic base region conductivities. The base doping profile in the SiGe drift-DHBT is controlled in such a way that it creates a net accelerating drift field in the quasi-neutral base for minority electrons. This accelerating field subsequently improves the current gain and cut-off frequency for the SiGe drift-DHBT in comparison with the SiGe DHBT for all levels of injection.

    DSM-IV, specifically its text revision DSM-IV-TR, remains the preferred diagnostic system. When employed in general population samples, prevalence estimates of bipolar disorder are relatively consistent across studies in Europe and USA. In community studies, first onset of bipolar mood disorder is usually in the mid-teenage years and twenties, and the occurrence of a major depressive episode or hypomania is usually its first manifestation. Since reliable criteria for delineating unipolar (UP) and bipolar (BI) depression cross-sectionally are currently lacking, there is a longitudinal risk - probably over 10% - that initial UP patients ultimately turn out as BP in the longer run. Its early onset implies a severe potential burden of disease in terms of impaired social and neuropsychological development, most of which is attributable to depression. BIPOLAR DEPRESSION IN CHILDREN: Bipolar I disorder is rare in prepubertal children, when defined according to unmodified DSM-IV-TR criteria. A broad diagnosis of bipolar disorder risks confounding with other childhood psychopathology and has less predictive value for bipolar disorder in adulthood than the conservative definition. Nevertheless, empirical studies of drug and other treatments and longitudinal studies to assess validity of the broadly defined phenotype in children and adolescents are desirable, rather than extrapolation from adult bipolar practice. The need for an increased capacity to conduct reliable trials in children and adolescents is a challenge to Europe, whose healthcare system should allow greater participation and collaboration than other regions, via clinical networks. ECNP will aspire to facilitate such developments. BIPOLAR DEPRESSION IN ADULTS - UNIPOLAR/BIPOLAR CONTRAST: Despite some differences in symptom profiles and severity measures, a cross-sectional categorical distinction between bipolar (BP) and unipolar (UP) depression is currently impossible. For regulatory purposes, a major depressive

    Full Text Available Objective: To compare the effects of topiramate versus valproate sodium as an add-on therapy to a combination of lithium and risperidone (Li+Ris on body weight and serum lipid profile in children and adolescents with bipolar disorder. Methods: In a single-blind randomized clinical trial, thirty children and adolescents with bipolar disorder type I in the manic or mixed phase ,treated with the combination of Li+Ris at therapeutic doses for at least 4 weeks who had the indication of add-on therapy due to a recurrent episode; a partial response or non response in the current episode or relapse were included. Participants were randomly assigned to receive either topiramate or sodium valproate as the third drug add-on therapy for a total of 6 weeks. Weight, height and serum lipid profiles were determined at baseline and at the end of week 6. Results: Differences in the mean levels of lipid profiles at baseline and after week 6 evaluation were not significant in both treatment groups. BMI z-score increased in both treatment groups, being significant only in the Li+Ris/Valproate group, increasing from (mean ±SD 0.38 ±0.55 to 0.72 ±1.23 (p<0.05. Between group changes in BMI z-score was not significant.Among the BMI percentile categories, participants in the normal weight subgroup showed a significant increase in BMI z-score during the 6 week trial, compared to overweight/obese subgroup, in both Li+Ris/Valproate and Li+Ris/Topiramate treatment groups. Elevated mean serum level of triglyceride and a high proportion of participants with elevated total cholesterol (≥ 170 mg/dl, triglyceride (≥ 110 mg/dl, and BMI percentile 85-<95 at baseline (before randomization and at the end of 6 week study were noted. Conclusion: When topiramate and valproate sodium are used for six weeks as adjunctive treatment to a combination of Li+Ris, they act alike on lipid milieu of children and adolescents with bipolar disorder.

    Full Text Available Background : The WHO estimates that more than 80% of African populations attend traditional healers for health reasons and that 40%–60% of these have some kind of mental illness. However, little is known about the profiles and outcome of this traditional approach to treatment. Objective : The purpose of this study was to describe the profiles and outcome of traditional healing practices for severe mental illnesses in Jinja and Iganga districts in the Busoga region of Eastern Uganda. Methods : Four studies were conducted. Study I used focus group discussions (FGDs with case vignettes with local community members and traditional healers to explore the lay concepts of psychosis. Studies II and III concerned a cross-sectional survey of patients above 18 years at the traditional healer's shrines and study IV was made on a prospective cohort of patients diagnosed with psychosis in study III. Manual content analysis was used in study I; quantitative data in studies II, III, and IV were analyzed at univariate, bivariate, and multivariate levels to determine the association between psychological distress and socio-demographic factors; for study IV, factors associated with outcome were analyzed. One-way ANOVA for independent samples was the analysis used in Study IV. Results : The community gave indigenous names to psychoses (mania, schizophrenia, and psychotic depression and had multiple explanatory models for them. Thus multiple solutions for these problems were sought. Of the 387 respondents, the prevalence of psychological distress was 65.1%, where 60.2% had diagnosable current mental illness, and 16.3% had had one disorder in their lifetime. Over 80% of patients with psychosis used both biomedical and traditional healing systems. Those who combined these two systems seemed to have a better outcome. All the symptom scales showed a percentage reduction of more than 20% at the 3- and 6-month follow-ups. Conclusion : Traditional healers shoulder a

    Although recently more research has considered children with bipolar disorder than in the past, much controversy still surrounds the validity of the diagnosis. Furthermore, questions remain as to whether or not childhood expressions of bipolarity are continuous with adult manifestations of the illness. In order to advance current knowledge of bipolar disorders in children, researchers have begun to conduct phenomenological, longitudinal, treatment, and neuroimaging studies in youths who exhibit symptoms of bipolar illness, as well as offspring of parents with bipolar disorders. Regardless of the differences between research groups regarding how bipolar disorder in children is defined, it is agreed that pediatric bipolarity is a serious and pernicious illness. With early intervention during the period of time in which youths are exhibiting subsyndromal symptoms of pediatric bipolarity, it appears that the progression of the illness to the more malignant manifestation of the disorder may be avoided. This paper will review what is currently known and what still is left to learn about clinically salient topics that pertain to bipolar disorder in children and adolescents.

    Children and adolescents with bipolar disorder often present with higher rates of mixed episodes, rapid cycling, and co-occurring attention-deficit/hyperactivity disorder than adults with bipolar disorder. It is unclear whether the differences in clinical presentation between youth and adults with bipolar disorder are due to differences in underlying etiologies or developmental differences in symptom manifestation. Neuroimaging studies of children and adolescents with bipolar disorder may clarify whether neurobiological abnormalities associated with early- and adult-onset bipolar disorder are distinct. Moreover, children and adolescents with bipolar disorder are typically closer to their illness onset than bipolar adults, providing a window of opportunity for identifying core neurobiological characteristics of the illness (ie, disease biomarkers) that are independent of repeated affective episodes and other confounding factors associated with illness course. Peer-reviewed publications of neuroimaging studies of bipolar children and adolescents were reviewed. Structural, neurochemical, and neurofunctional abnormalities in prefrontal and medical temporal and subcortical limbic structures, including the striatum, amygdala, and possibly hippocampus, are present in children and adolescents with bipolar disorder. Differences between neurobiological abnormalities in bipolar youth and adults as well as recommendations for future research directions are discussed.

    Research on the relationship between creativity and mental illness is summarized, and studies documenting a relationship in writers between creativity and affective illness (particularly bipolar illness) are described. Writers have a high prevalence of affective illness, and both affective illness and creativity have increased frequency in their first-degree relatives. The clinical management of the creative individual is challenging. In general, creative individuals are most productive when their affective symptoms are under good control.

  8. Mixed features in bipolar disorder.

    Mixed affective states, defined as the coexistence of depressive and manic symptoms, are complex presentations of manic-depressive illness that represent a challenge for clinicians at the levels of diagnosis, classification, and pharmacological treatment. The evidence shows that patients with bipolar disorder who have manic/hypomanic or depressive episodes with mixed features tend to have a more severe form of bipolar disorder along with a worse course of illness and higher rates of comorbid conditions than those with non-mixed presentations. In the updated Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5), the definition of "mixed episode" has been removed, and subthreshold nonoverlapping symptoms of the opposite pole are captured using a "with mixed features" specifier applied to manic, hypomanic, and major depressive episodes. However, the list of symptoms proposed in the DSM-5 specifier has been widely criticized, because it includes typical manic symptoms (such as elevated mood and grandiosity) that are rare among patients with mixed depression, while excluding symptoms (such as irritability, psychomotor agitation, and distractibility) that are frequently reported in these patients. With the new classification, mixed depressive episodes are three times more common in bipolar II compared with unipolar depression, which partly contributes to the increased risk of suicide observed in bipolar depression compared to unipolar depression. Therefore, a specific diagnostic category would imply an increased diagnostic sensitivity, would help to foster early identification of symptoms and ensure specific treatment, as well as play a role in suicide prevention in this population.

    Full Text Available From a neurobiological perspective there is no such thing as bipolar disorder. Rather, it is almost certainly the case that many somewhat similar, but subtly different, pathological conditions produce a disease state that we currently diagnose as bipolarity. This heterogeneity—reflected in the lack of synergy between our current diagnostic schema and our rapidly advancing scientific understanding of the condition—limits attempts to articulate an integrated perspective on bipolar disorder. However, despite these challenges, scientific findings in recent years are beginning to offer a provisional unified field theory of the disease. This theory sees bipolar disorder as a suite of related neurodevelopmental conditions with interconnected functional abnormalities that often appear early in life and worsen over time. In addition to accelerated loss of volume in brain areas known to be essential for mood regulation and cognitive function, consistent findings have emerged at a cellular level, providing evidence that bipolar disorder is reliably associated with dysregulation of glial-neuronal interactions. Among these glial elements are microglia—the brain’s primary immune elements, which appear to be overactive in the context of bipolarity. Multiple studies now indicate that inflammation is also increased in the periphery of the body in both the depressive and manic phases of the illness, with at least some return to normality in the euthymic state. These findings are consistent with changes in the HPA axis, which are known to drive inflammatory activation. In summary, the very fact that no single gene, pathway or brain abnormality is likely to ever account for the condition is itself an extremely important first step in better articulating an integrated perspective on both its ontological status and pathogenesis. Whether this perspective will translate into the discovery of innumerable more homogeneous forms of bipolarity is one of the great

    Studies have demonstrated relationships between creativity and bipolar disorder (BD) in individuals, and suggested familial transmission of both creativity and BD. However, to date, there have been no studies specifically examining creativity in offspring of bipolar parents and clarifying mechanisms of intergenerational transmission of creativity. We compared creativity in bipolar parents and their offspring with BD and bipolar offspring with attention-deficit/hyperactivity disorder (ADHD) with healthy control adults and their children. 40 adults with BD, 20 bipolar offspring with BD, 20 bipolar offspring with ADHD, and 18 healthy control parents and their healthy control children completed the Barron-Welsh Art Scale (BWAS), an objective measure of creativity. Adults with BD compared to controls scored significantly (120%) higher on the BWAS Dislike subscale, and non-significantly (32%) higher on the BWAS Total scale. Mean BWAS Dislike subscale scores were also significantly higher in offspring with BD (107% higher) and offspring with ADHD (91% higher) than in healthy control children. Compared to healthy control children, offspring with BD had 67% higher and offspring with ADHD had 40% higher BWAS Total scores, but these differences failed to reach statistical significance when adjusted for age. In the bipolar offspring with BD, BWAS Total scores were negatively correlated with duration of illness. The results of this study support an association between BD and creativity and contribute to a better understanding of possible mechanisms of transmission of creativity in families with genetic susceptibility for BD. This is the first study to show that children with and at high risk for BD have higher creativity than healthy control children. The finding in children and in adults was related to an enhanced ability to experience and express dislike of simple and symmetric images. This could reflect increased access to negative affect, which could yield both benefits

    2016-04-01

    Bipolar disorder in youth substantially impairs behavior, family, and social functioning and interferes with developmental course. There is increasing interest in defining a bipolar prodrome similar to that reported in early-onset psychosis that will allow for earlier intervention and reduction in overall morbidity and mortality. Several lines of research have addressed this important issue including studies of offspring of bipolar parents, high-risk cohorts, and longitudinal follow-up of subjects with major depressive disorder (MDD), ADHD, and bipolar spectrum disorder. The development and validation of bipolar prodrome rating scales also shows promise. Recent attempts to intervene at earlier stages of bipolar disorder have led to some positive outcomes. However, a controversy remains concerning the identification and management of the earliest symptoms. Further research is needed to fully validate a bipolar prodrome and to determine the optimal course of action at various stages of illness.

    A bipolar electrode (BPE) is an electrically conductive material that promotes electrochemical reactions at its extremities (poles) even in the absence of a direct ohmic contact. More specifically, when sufficient voltage is applied to an electrolyte solution in which a BPE is immersed, the potential difference between the BPE and the solution drives oxidation and reduction reactions. Because no direct electrical connection is required to activate redox reactions, large arrays of electrodes can be controlled with just a single DC power supply or even a battery. The wireless aspect of BPEs also makes it possible to electrosynthesize and screen novel materials for a wide variety of applications. Finally, bipolar electrochemistry enables mobile electrodes, dubbed microswimmers, that are able to move freely in solution. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

A herança do transtorno bipolar é complexa, envolve vários genes, além de apresentar heterogeneidade e interação entre fatores genéticos e não-genéticos. Achados, que já foram replicados, já implicaram os cromossomos 4, 12, 18 e 21, entre outros, na busca por genes de suscetibilidade. Os resultados mais promissores foram obtidos através de estudos de ligação. Por outro lado, os estudos de associação geraram dados interessantes, mas ainda vagos. Os estudos de populações de pacientes homogêneos e a melhor definição do fenótipo deverão contribuir para avanços futuros. A identificação dos genes relacionados ao transtorno bipolar irá permitir o melhor entendimento e tratamento dessa doença.

  18. Staging of unipolar affective illness

    Full Text Available In this article, a concept of staging of unipolar affective illness (recurrent depression is presented. In respective subchapters, three most important aspects of this issue have been discussed: 1 staging of unipolar affective illness; 2 staging of treatment-resistant depression; and 3 conversion of unipolar into bipolar affective illness. The evidence for so called neuroprogression of the illness, accumulated in recent years, has allowed for a classification of staging based on a concept of allostasis and allostatic load. In the course of illness, changes in neuroendocrine system (mainly hypothalamic pituitary-adrenal (HPA axis, immunological system, mechanisms of oxidative stress, neurotransmitters, neurotrophic factors as well as structural and functional changes of the brain occur. In their paper of 2007, Fava and Tossani elaborated a concept of staging of unipolar affective illness presenting a continuum model of five consecutive stages with specific clinical features. In the present paper, a concept of treatment-resistant depression and staging of treatment resistance is presented in the context of several models. An important determinant of treatment-resistant depression is so called subthreshold bipolarity which is connected with worse efficacy of antidepressant drugs. In the course of illness, there is a possibility of changing diagnosis from recurrent depression into bipolar affective illness. The studies on this issue show that frequency of such diagnostic conversion is 1,5% of depressed patients per year.

    Bipolar disorders are major mood disorders defined by the presence of discrete episodes of depression and either mania, in bipolar I disorder, or hypomania, in bipolar II disorder. There is little contention that both are serious psychiatric conditions or that they are associated with substantial suffering, disability, risk of suicide and cost to the community. Recently, focus has shifted away from classic manic-depressive illness toward a 'bipolar spectrum' model, which allows for much softer presentations to be conceptualized as bipolarity, but the boundaries of this concept remain contentious. In this article, we will consider the contribution of neuroimaging to delineating the bipolar phenotype and differentiating it from similar disorders.

On the other hand, we noted that unipolar patients differ from bipolar patients in terms of the frequency of hospitalizations (3.5 vs. 3.1) and the length of stays in hospitals (25.8 vs. 20.7 days) with significant differences of 0.003 and 0.0000001 respectively. Moreover, the CGI scores of unipolar patients are higher than those of bipolar patients. However, the difference is not significant. Consequently, an early distinction between bipolar and unipolar disorder is of utmost importance for the treatment of these two illnesses.

  1. Inflammation's Association with Metabolic Profiles before and after a Twelve-Week Clinical Trial in Drug-Naive Patients with Bipolar II Disorder.

    Full Text Available Inflammation is thought to be involved in the pathophysiology of bipolar disorder (BP and metabolic syndrome. Prior studies evaluated the association between metabolic profiles and cytokines only during certain mood states instead of their changes during treatment. We enrolled drug-naïve patients with BP-II and investigated the correlation between changes in mood symptoms and metabolic indices with changes in plasma cytokine levels after 12 weeks of pharmacological treatment. Drug-naïve patients (n = 117 diagnosed with BP-II according to DSM-IV criteria were recruited. Metabolic profiles (cholesterol, triglyceride, HbA1C, fasting serum glucose, body mass index (BMI and plasma cytokines (TNF-α, CRP, IL-6, and TGF-β were measured at baseline and 2, 8, and 12 weeks post-treatment. To adjust within-subject dependence over repeated assessments, multiple linear regressions with generalized estimating equation methods were used. Seventy-six (65.0% patients completed the intervention. Changes in plasma CRP were significantly associated with changes in BMI (P = 1.7E-7 and triglyceride (P = 0.005 levels. Changes in plasma TGF-β1 were significantly associated with changes in BMI (P = 8.2E-6, cholesterol (P = 0.004, and triglyceride (P = 0.006 levels. However, changes in plasma TNF-α and IL-6 were not associated with changes in any of the metabolic indices. Changes in Hamilton Depression Rating Scale scores were significantly associated with changes in IL-6 (P = 0.003 levels; changes in Young Mania Rating Scale scores were significantly associated with changes in CRP (P = 0.006 and TNF-α (P = 0.039 levels. Plasma CRP and TGF-β1 levels were positively correlated with several metabolic indices in BP-II after 12 weeks of pharmacological intervention. We also hypothesize that clinical symptoms are correlated with certain cytokines. These new findings might be important evidence that inflammation is the pathophysiology

    Full Text Available In this investigation, the pharmacokinetic variables of continuous infusion and intermittent bolus injection of furosemide and the possible relationship between its pharmacokinetic characteristics and pharmacodynamic profile among intensive care unit (ICU patients were studied. In this prospective, randomized, clinical trial, twelve patients received IV bolus of 20 mg of the drug during 3 hours period and, the drug dose was doubled, when the urine output was less than 1 ml/kg/h (group 1. The other nine patients received a continuous intravenous furosemide infusion at the rate of 0.1 mg/kg/h (group 2. The amount of furosemide in serum was measured by high performance liquid chromatography (HPLC. Results showed a positive correlation between plasma clearance of furosemide and its diuretic activity (P=0.01. The pharmacokinetic parameters such as Vd (l, CL (ml/min, Ke (min-1 and t½ (min in continuous infusion patients were not significantly differed from the bolus patients (P-values 0.5, 0.9, 0.9,0.9, respectively. Nevertheless the observed plasma clearance of drug in the continuous infusion group was clinically higher than bolus injection group and as a result the cumulative urine output per hour per mg of furosemide in a continuous infusion was observed to be higher than bolus(P=0.2. Changes in serum sodium and potassium were similar for both groups, but bolus injection patients were associated with higher potassium depletion (P=0.001. Therefore, continuous infusion seems to be better means of diuretic therapy in critically ill patients.

    2014-04-01

    Full Text Available In bipolar disorder illness progression has been associated with a higher number of mood episodes and hospitalizations, poorer response to treatment, and more severe cognitive and functional impairment. This supports the notion of the use of staging models in this illness. The value of staging models has long been recognized in many medical and malignant conditions. Staging models rely on the fact that different interventions may suit different stages of the disorder, and that better outcomes can be obtained if interventions are implemented earlier in the course of illness. Thus, treatment planning would benefit from the assessment of cognition, functioning and comorbidities. Staging may offer a means to refine treatment options, and most importantly, to establish a more precise diagnosis. Moreover, staging could have utility as course specifier and may guide treatment planning and better information to patients and their family members of what could be expected in terms of prognosis. The present study reviews the clinical and biological basis of the concept of illness progression in bipolar disorder.

    Objective To determine whether abnormalities of impulse control persist across the course of bipolar disorder, thereby representing potential state markers and endophenotypes. Methods Impulse control of 108 bipolar I manic or mixed patients was measured on three tasks designed to study response inhibition, ability to delay gratification, and attention; namely a stop signal task, a delayed reward task, and a continuous performance task, respectively. Barrett Impulsivity Scale (BIS-11) scores were also obtained. Patients were then followed for up to one year and re-assessed with the same measures if they developed depression or euthymia. Healthy comparison subjects were also assessed with the same instruments on two occasions to assess measurement stability. Results At baseline, bipolar subjects demonstrated significant deficits on all three tasks as compared to healthy subjects, consistent with more impulsive responding in the bipolar manic/mixed group. In general, performance on the three behavioral tasks normalized upon switching to depression or developing euthymia. In contrast, BIS-11 scores were elevated during mania and remained elevated as bipolar subjects developed depression or achieved euthymia. Conclusions Bipolar I disorder patients demonstrate deficits on laboratory tests of various aspects of impulsivity when manic, as compared to healthy subjects, that largely normalize with recovery and switching into depression. However, elevated BIS scores persist across phases of illness. These findings suggest that impulsivity has both affective-state dependent and trait components in bipolar disorder. PMID:20565435

    2014-01-01

    It has become common to say psychiatric illnesses are brain diseases. This reflects a conception of the mental as being biologically based, though it is also thought that thinking of psychiatric illness this way will reduce the stigma attached to psychiatric illness. If psychiatric illnesses are brain diseases, however, it is not clear why psychiatry should not collapse into neurology, and some argue for this course. Others try to maintain a distinction by saying that neurology deals with abnormalities of neural structure while psychiatry deals with specific abnormalities of neural functioning. It is not clear that neurologists would accept this division, nor that they should. I argue that if we take seriously the notion that psychiatric illnesses are mental illnesses we can draw a more defensible boundary between psychiatry and neurology. As mental illnesses, psychiatric illnesses must have symptoms that affect our mental capacities and that the sufferer is capable of being aware of, even if they are not always self-consciously aware of them. Neurological illnesses, such as stroke or multiple sclerosis, may be diagnosed even if they are silent, just as the person may not be aware of having high blood pressure or may suffer a silent myocardial infarction. It does not make sense to speak of panic disorder if the person has never had a panic attack, however, or of bipolar disorder in the absence of mood swings. This does not mean psychiatric illnesses are not biologically based. Mental illnesses are illnesses of persons, whereas other illnesses are illnesses of biological individuals.

    We studied the characteristics of family functioning in bipolar children and healthy comparison children. We hypothesized that the family environment of bipolar children would show greater levels of dysfunction as measured by the Family Environment Scale (FES). We compared the family functioning of 36 families that included a child with DSM-IV bipolar disorder versus 29 comparison families that included only healthy children. All subjects and their parents were assessed with the K-SADS-PL interview. The parents completed the FES to assess their current family functioning. Multivariate analysis of variance was used to compare the family environment of families with and without offspring with bipolar disorder. Parents of bipolar children reported lower levels of family cohesion (pparents with no bipolar children. Secondary analyses within the bipolar group revealed lower levels of organization (p=0.031) and cohesion (p=0.014) in families where a parent had a history of mood disorders compared to families where parents had no history of mood disorders. Length of illness in the affected child was inversely associated with family cohesion (r=-0.47, p=0.004). Due to the case-control design of the study, we cannot comment on the development of these family problems or attribute their cause specifically to child bipolar disorder. Families with bipolar children show dysfunctional patterns related to interpersonal interactions and personal growth. A distressed family environment should be addressed when treating children with bipolar disorder.

    Full Text Available Alexandra K Gold,1 Louisa G Sylvia,1,2 1Department of Psychiatry, Massachusetts General Hospital, 2Harvard Medical School, Boston, MA, USA Abstract: Bipolar disorder is a serious mental illness characterized by alternating periods of elevated and depressed mood. Sleep disturbances in bipolar disorder are present during all stages of the condition and exert a negative impact on overall course, quality of life, and treatment outcomes. We examine the partnership between circadian system (process C functioning and sleep–wake homeostasis (process S on optimal sleep functioning and explore the role of disruptions in both systems on sleep disturbances in bipolar disorder. A convergence of evidence suggests that sleep problems in bipolar disorder result from dysregulation across both process C and process S systems. Biomarkers of depressive episodes include heightened fragmentation of rapid eye movement (REM sleep, reduced REM latency, increased REM density, and a greater percentage of awakenings, while biomarkers of manic episodes include reduced REM latency, greater percentage of stage I sleep, increased REM density, discontinuous sleep patterns, shortened total sleep time, and a greater time awake in bed. These findings highlight the importance of targeting novel treatments for sleep disturbance in bipolar disorder. Keywords: bipolar disorder, circadian rhythms, sleep–wake homeostasis

    It has been known for a long time that people with salient social and artistic creativity suffer more frequently from psychiatric illnesses than the average population. In their review paper, the authors assess the Hungarian and international scientific literature regarding the association of creativity and psychopathology. They conclude that contrary to the concept prevailing in the first part of the 20th century about the strong association between schizophrenia and creativity, the results of empirical research now unambiguously suggest that prominent social and artistic creativity is associated primarily with affective, and more specifically with bipolar affective illnesses. In addition, we already know that as regards the development of creativity, it is not the given affective (depressive, manic, hypomanic) episode which is important, but the hyperthymic or cyclothymic temperament structure which also predisposes for affective illness.

  16. Investigation of carbon profiles for enhanced boron confinement and improved carrier transport in strained silicon germanium nanolayers for heterojunction bipolar transistors

    Enicks, Darwin Gene

    This research covers a breadth of topics, in Chapters 1 through 7, ranging from the crystal lattice, to dopant diffusion in SiGe, to SiGe and SiGeC chemical vapor deposition, to the Si/SiGe and Si/SiGeC energy band structure, and NPN SiGeC HBT AC and DC characteristics. Chapters 8 and 9 contain the results of the research, which relates the film growth and carbon positioning to boron diffusion, sheet resistance, and device performance; specifically current gain, fmax, and noise figures of merit. The first objective of the dissertation was to investigate carbon doping profiles in nano-layers (≤32 nm) of silicon germanium (Si1-xGe x), and provide an understanding of "remote carbon boron confinement" (RCBC), which is demonstrated to exploit the advantages of carbon to increase NPN HBT (heterojunction bipolar transistor) performance, reduce base resistance, and improve overall noise figures of merit. The second objective was to investigate the noise characteristics of this method compared to the standard method of placing carbon throughout the lattice, which is known as "uniform carbon boron confinement" (UCBC). The current technological development towards smaller and faster devices has forced engineers and scientists to look into materials other than silicon, but which are highly compatible. A natural choice is the Si1-xGe x alloy, since Ge is also a Group IV. Si1-xGex has the same lattice structure as Si, but its lattice constant is 4.2% larger (aSi = 0.543nm, aGe = 0.567nm), and the bandgap is less than that of Si (Eg_Si = 1.11eV, Eg_Ge = 0.67eV). This opens the possibility of bandgap, strain, and dopant diffusion engineering, all of which affect the material and electronic properties of devices. The primary benefit of carbon is to reduce the diffusion of boron in Si1-xGex thus keeping the base narrow for significantly reduced electron transit times and increased unity gain cutoff frequencies (fT). However the utilization of carbon reduces base conductivity and

    Recent treatment guidelines support treatment of biological rhythm abnormalities as a part of treatment of bipolar disorder, but still, literature examining various domains (Sleep, Activity, Social, and Eating) of biological rhythm and its clinical predictors are less. The main aim of our study is to compare various domains of biological rhythm among remitted bipolar I subjects and healthy controls. We also explored for any association between clinical variables and biological rhythm among bipolar subjects. 40 subjects with Bipolar I disorder and 40 healthy controls who met inclusion and exclusion criteria were recruited for the study. Diagnoses were ascertained by a qualified psychiatrist using MINI 5.0. Sociodemographic details, biological rhythm (BRIAN-Biological Rhythm Interview of assessment in Neuropsychiatry) and Sleep functioning (PSQI- Pittsburgh Sleep Quality Index) were assessed in all subjects. Mean age of the Bipolar subjects and controls were 41.25±11.84years and 38.25±11.25 years respectively. Bipolar subjects experienced more biological rhythm disturbance when compared to healthy controls (total BRIAN score being 34.25±9.36 vs 28.2±6.53) (p=0.002). Subsyndromal depressive symptoms (HDRS) had significant positive correlation with BRIAN global scores(r=0.368, p=0.02). Linear regression analysis showed that number of episodes which required hospitalization (β=0.601, t=3.106, P=0.004), PSQI (β=0.394, t=2.609, p=0.014), HDRS (β=0.376, t=2.34, t=0.036) explained 31% of variance in BRIAN scores in remitted bipolar subjects. Biological rhythm disturbances seem to persist even after clinical remission of bipolar illness. More studies to look into the impact of subsyndromal depressive symptoms on biological rhythm are needed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available To review the data with respect to prevalence and risk factors of metabolic syndrome (MetS in bipolar disorder patients. Electronic searches were done in PUBMED, Google Scholar and Science direct. From 2004 to June 2011, 34 articles were found which reported on the prevalence of MetS. The sample size of these studies varied from 15 to 822 patients, and the rates of MetS vary widely from 16.7% to 67% across different studies. None of the sociodemographic variable has emerged as a consistent risk factor for MetS. Among the clinical variables longer duration of illness, bipolar disorder- I, with greater number of lifetime depressive and manic episodes, and with more severe and difficult-to-treat index affective episode, with depression at onset and during acute episodes, lower in severity of mania during the index episode, later age of onset at first manic episode, later age at first treatment for the first treatment for both phases, less healthy diet as rated by patients themselves, absence of physical activity and family history of diabetes mellitus have been reported as clinical risk factors of MetS. Data suggests that metabolic syndrome is fairly prevalent in bipolar disorder patients.

    It has been estimated that the heritable component of bipolar disorder ranges between 80 and 90%. However, even genome-wide association studies explain only a fraction of phenotypic variability not resolving the problem of "lost heritability". Although direct evidence for epigenetic dysfunction in bipolar disorder is still limited, methodological technologies in epigenomic profiling have advanced, offering even single cell analysing and resolving the problem of cell heterogeneity in epigenetics research. Gene overlapping with other mental disorders represents another problem in identifying potential susceptibility genes in bipolar disorder. Better understanding of the interplay between multiple environmental and genetic factors involved in the patogenesis of bipolar disorder could provide relevant information for treatment of patients with this complex disorder. Future studies on the role of these factors in psychopathological conditions, subphenotypes and endophenotypes may greatly benefit by using more precise clinical data and a combined approach with multiple research tools incorporated into a single study.

    There is growing recognition that bipolar disorder frequently first presents in adolescence. Preadolescents with volatile behavior and severe mood swings also comprise a large group of patients whose difficulties may lie within the bipolar spectrum. However, the preponderance of scientific effort and clinical trials for this condition has focused on adults. This review summarizes the complexity of bipolar disorder and diagnosis of the disease among young people. It proceeds to review the principles of pharmacotherapy, assess current treatment options and to highlight areas where evidence-based guidance is lacking. Recent developments have enlarged the range of potential treatments for bipolar disorder. Nonetheless, differences in the phenomenology, course and sequelae of bipolar disorder among young people compel greater attention to the benefits and liabilities of therapy for those affected by this illness' early onset. By summarizing current research and opinion on diagnostic issues and treatment approaches, this review aims to provide an update on a clinically important yet controversial topic.

    Full Text Available Metabolomic profiling was carried out on 53 post-mortem brain samples from subjects diagnosed with schizophrenia, depression, bipolar disorder (SDB, diabetes, and controls. Chromatography on a ZICpHILIC column was used with detection by Orbitrap mass spectrometry. Data extraction was carried out with m/z Mine 2.14 with metabolite searching against an in-house database. There was no clear discrimination between the controls and the SDB samples on the basis of a principal components analysis (PCA model of 755 identified or putatively identified metabolites. Orthogonal partial least square discriminant analysis (OPLSDA produced clear separation between 17 of the controls and 19 of the SDB samples (R2CUM 0.976, Q2 0.671, p-value of the cross-validated ANOVA score 0.0024. The most important metabolites producing discrimination were the lipophilic amino acids leucine/isoleucine, proline, methionine, phenylalanine, and tyrosine; the neurotransmitters GABA and NAAG and sugar metabolites sorbitol, gluconic acid, xylitol, ribitol, arabinotol, and erythritol. Eight samples from diabetic brains were analysed, six of which grouped with the SDB samples without compromising the model (R2 CUM 0.850, Q2 CUM 0.534, p-value for cross-validated ANOVA score 0.00087. There appears on the basis of this small sample set to be some commonality between metabolic perturbations resulting from diabetes and from SDB.

    The presence of psychotic symptoms in bipolar disorder (BD) is considered a feature of higher severity of illness and, in particular, of manic episodes in bipolar I disorder (BD I). However, the possibility to apply the "with psychotic features" specifier to major depressive episodes in either bipolar II disorder (BD II) or BD I highlights the need for additional research in this area. The present study assessed the lifetime presence of psychotic symptoms and related socio-demographic and clinical features in a large sample of BD patients (N=360), with (BDPs, N=207) and without a lifetime history of psychosis (BDNPs, N=153). An overall less favorable socio-demographic profile was observed in BDPs vs BDNPs. In terms of clinical variables, BDPs vs BDNPs had: earlier age at onset (27.7±10.5 vs 30.1±12.3years; p=0.02), higher rates of BD I diagnosis (95.7% vs 45.8%; psocio-demographic and certain clinical characteristics associated with the lifetime presence of psychotic symptoms in bipolar patients.

    The onset of severe, chronic or recurrent psychiatric illnesses, such as schizophrenia-spectrum and bipolar disorders, is a dramatic clinical event often detectable during adolescence and even in childhood. At any age, pharmacotherapy, along with enhancement of social skills and family support, is the mainstay for the management of such disorders. The aim of this review is to critically analyze findings from randomized controlled trials (RCTs) that have investigated the clinical utility of second-generation antipsychotics (SGAs) for the treatment of early-onset schizophrenia and bipolar disorders. Eighteen studies were considered, all of which were unfortunately impaired by methodologic limitations, such as the paucity of long-term data and lack of a three-arm comparison (SGA vs SGA vs placebo). Nevertheless, the results of this review allow us to suggest the effectiveness of three SGAs (aripiprazole, olanzapine, and risperidone) in the short-term treatment of both early-onset schizophrenia and bipolar mania, although such agents show different safety profiles. The use of clozapine should be strictly limited to patients with non-affective, psychotic symptoms who do not respond to any of these three SGAs. In contrast, the use of quetiapine and ziprasidone in young patients with either affective or non-affective psychosis is not yet supported by evidence-based information. Given our findings, further studies are urgently required to identify the best treatment option(s) for pediatric bipolar disorder (especially the depressive phase) and the long-term management of early-onset schizophrenia.

    Decreased need for sleep has been proposed as a core symptom of mania and it has been associated with the pathogenesis of Bipolar Disorder. The emergence of Disruptive Mood Dysregulation Disorder (DMDD) as a new diagnostic has been controversial and much has been speculated about its relationship with the bipolar spectrum. REM sleep fragmentation could be a biomarker of affective disorders and it would help us to differentiate them from other disorders. Polysomnographic cross-sectional study of children with DMDD, bipolar disorder and Attention Deficit Hyperactivity Disorder (ADHD). All participants underwent a psychiatric semi-structured interview to obtain the diagnosis, comorbidities and primary sleep disorders. DMDD’s sample was performed following DSM5 criteria. Perform polysomnography in a sample of bipolar, DMDD and ADHD children and compare their profiles to provide more evidence about the differences or similarities between bipolar disorder and DMDD. Bipolar group had the highest REM density values while ADHD had the lowest. REM density was not statiscally different between bipolar phenotypes. REM density was associated with antidepressant treatment, episodes of REM and their interaction. REM latency was associated with antipsychotic treatment and school performance. Bipolar patients had higher scores on the depression scale than DMDD and ADHD groups. No significant differences between the two compared affective disorders were found. However there were differences in REM density between bipolar and ADHD groups. REM sleep study could provide a new theoretical framework to better understand the pathogenesis of pediatric bipolar disorder.

    Full Text Available OBJECTIVE: Although bipolar disorder is a major contributor to functional impairment worldwide, an independent impact of bipolar disorder and ageing on functioning has yet to be demonstrated. The objective of the present study was to evaluate the effect of bipolar disorder on age-related functional status using matched controls as a standard. METHOD: One-hundred patients with bipolar disorder and matched controls were evaluated for disability. Age-related effects controlled for confounders were cross-sectionally evaluated. RESULTS: Patients were significantly more impaired than controls. Regression showed effects for aging in both groups. The effect, size, however, was significantly stronger in patients. CONCLUSION: Bipolar disorder was an important effect modifier of the age impact on functioning. While a longitudinal design is needed to effectively demonstrate this different impact, this study further depicts bipolar disorder as a chronic and progressively impairing illness.OBJETIVO: O transtorno bipolar é responsável por importante parcela do prejuízo funcional ao redor do mundo.

    Objective The risk-benefit profile of antidepressant medications in bipolar disorder is controversial. When conclusive evidence is lacking, expert consensus can guide treatment decisions. The International Society for Bipolar Disorders (ISBD) convened a task force to seek consensus recommendations on the use of antidepressants in bipolar disorders. Method An expert task force iteratively developed consensus through serial consensus-based revisions using the Delphi method. Initial survey items were based on systematic review of the literature. Subsequent surveys included new or reworded items and items that needed to be rerated. This process resulted in the final ISBD Task Force clinical recommendations on antidepressant use in bipolar disorder. Results There is striking incongruity between the wide use of and the weak evidence base for the efficacy and safety of antidepressant drugs in bipolar disorder. Few well-designed, long-term trials of prophylactic benefits have been conducted, and there is insufficient evidence for treatment benefits with antidepressants combined with mood stabilizers. A major concern is the risk for mood switch to hypomania, mania, and mixed states. Integrating the evidence and the experience of the task force members, a consensus was reached on 12 statements on the use of antidepressants in bipolar disorder. Conclusions Because of limited data, the task force could not make broad statements endorsing antidepressant use but acknowledged that individual bipolar patients may benefit from antidepressants. Regarding safety, serotonin reuptake inhibitors and bupropion may have lower rates of manic switch than tricyclic and tetracyclic antidepressants and norepinephrine-serotonin reuptake inhibitors. The frequency and severity of antidepressant-associated mood elevations appear to be greater in bipolar I than bipolar II disorder. Hence, in bipolar I patients antidepressants should be prescribed only as an adjunct to mood-stabilizing medications

    Over the past few years there has been a surge of interest in the study of bipolar postpartum depression (PPD); however, questions remain about its prevalence, screening, clinical features, and treatment. Three electronic databases, MEDLINE/PubMed (1966-2016), PsycINFO (1806-2016), and the Cochrane Database of Systematic Reviews, were searched using a combination of the keywords bipolar, depression, postpartum, peripartum, prevalence, screening, diagnosis, treatment, drugs, and psychotherapy. The reference lists of articles identified were also searched. All relevant articles published in English were included. Depending on the population studied, 21.4-54% of women with PPD have a diagnosis of bipolar disorder (BD). Characteristic clinical features include younger age at illness onset, first onset of depression after childbirth, onset immediately after delivery, atypical depressive symptoms, psychotic features, mixed features, and history of BD in first-degree family members. Treatment should be guided by symptom acuity, safety concerns, the patient's response to past treatments, drug tolerability, and breastfeeding preference. In the absence of controlled treatment data, preference should be given to drugs normally indicated for bipolar depression including lithium, quetiapine and lamotrigine. Although antidepressants have been studied in combination with mood stabilizers in bipolar depression, these drugs should be avoided due to likelihood of elevated risk of induction of manic symptoms in the postpartum period. In the postpartum period, bipolar PPD is common, can be differentiated from unipolar PPD, and needs to be identified promptly in order to expedite appropriate treatment. Future studies on pharmacotherapy and psychotherapy should focus on the acute and preventative treatment of bipolar PPD. Copyright © 2017 Elsevier B.V. All rights reserved.

    There is increased recognition that bipolar disorder has an early age of onset. The prevalence of bipolar disorder in prepubertal children has not been determined, however the prevalence in adolescence is approximately 1%. Bipolar disorder in children poses a diagnostic challenge since the symptoms may differ from those in late adolescence and adulthood. Comorbid disorders, such as attention-deficit/hyperactivity disorder, further complicate both the diagnosis and course of the disorder. There is increasing evidence of the chronicity and severity of this disorder in youths. Bipolar disorder significantly disrupts a child's psychosocial development including impairments in academic functioning, family functioning, and relationship with peers. Although this disorder has significant morbidity in children and adolescents, there is a paucity of controlled studies to assess the efficacy and safety of mood stabilizers in the treatment of this disorder in youths. The treatment literature consists largely of case studies, retrospective chart reviews, and open-label studies. There is a compelling need for double-blind, placebo-controlled trials to determine whether commonly used medications to treat this disorder are significantly superior to placebo. Since many children in clinical practice require more than one psychotropic medication to adequately manage this disorder, studies of combination treatments are warranted. This review will provide an overview of the literature of bipolar disorder in children and adolescents, including discussion of the prevalence, diagnosis, epidemiology, course of the illness, and treatment issues.

The essential diagnostic criterion for BD is episodes of mania or hypomania; however, the patients report that the majority of their time is spent in a depressive phase. Current treatment options for this component of BD have yet to achieve satisfactory remission rates. Lurasidone is a drug in the benzisothiazole class approved by the US Food and Drug Administration in June 2013 for the acute treatment of bipolar depression. Its pharmacological profile features high-affinity antagonism at D2, 5-HT2A, and 5-HT7 receptors; moderate-affinity antagonism at α2C-adrenergic receptors; low- to very low-affinity antagonism at α1A-adrenergic, α2A-adrenergic, H1, M1, and 5-HT2C receptors; and high-affinity partial agonism at 5-HT1A. Preliminary findings from two recent double-blinded clinical trials suggest that lurasidone is efficacious in treating bipolar I depression, with clinical effects manifesting as early as the first 2–3 weeks of treatment (as measured by the Montgomery–Åsberg Depression Rating Scale and Clinical Global Impressions Scale for use in bipolar illness. Its therapeutic benefit appears to be comparable to the current US Food and Drug Administration-indicated treatments: quetiapine and olanzapine–fluoxetine, according to a measure of effect size known as number needed to treat. These studies reported relatively limited extrapyramidal and metabolic side effects as a result of treatment with lurasidone, with the most common side

    Full Text Available It has become common to say psychiatric illnesses are brain diseases. This reflects a conception of the mental as being biologically based, though it is also thought that thinking of psychiatric illness this way will reduce the stigma attached to psychiatric illness. If psychiatric illnesses are brain diseases, however, it is not clear why psychiatry should not collapse into neurology, and some argue for this course. Others try to maintain a distinction by saying that neurology deals with abnormalities of neural structure while psychiatry deals with specific abnormalities of neural functioning. It is not clear that neurologists would accept this division, nor that they should. I argue that if we take seriously the notion that psychiatric illnesses are mental illnesses we can draw a more defensible boundary between psychiatry and neurology. As mental illnesses, psychiatric illnesses must have symptoms that affect our mental capacities and that the sufferer is capable of being aware of, even if they are not always self-consciously aware of them. Neurological illnesses, such as stroke or multiple sclerosis, may be diagnosed even if they are silent, just as the person may not be aware of having high blood pressure or may suffer a silent myocardial infarction. It does not make sense to speak of panic disorder if the person has never had a panic attack, however, or of bipolar disorder in the absence of mood swings. This does not mean psychiatric illnesses are not biologically based. Mental illnesses are illnesses of persons, whereas other illnesses are illnesses of biological individuals.

MATERIAL AND METHODS: Three-hundred adult patients suffering from various chronic diseases participated in the study. The patients' mean age was 54.6 years (SD = 17.57. RESULTS: No statistically significant differences were found between the different clinical groups in health-related behavior, acceptance of illness, internal HLC or chance HLC. Patients with neurologic conditions showed slightly lower powerful others HLC than did some other clinical groups. Health-related behavior was significantly positively related to all three categories of HLC, with most prominent associations observed with powerful others HLC. Only one type of health-related behavior--preventive behavior--correlated significantly and negatively with acceptance of illness. Differences in the frequency of health-related behavior were also found due to gender (women showing more healthy nutritional habits than men, age (older subjects showing more frequent health-promoting behavior, education (higher education was associated with less frequent health-promoting behavior and marital status (widowed subjects reporting more frequent health-promoting behavior. CONCLUSIONS: Health-related behavior in patients with chronic diseases seems to be unrelated to a specific diagnosis; however it shows associations with both internal and external HLC. Sociodemographic factors are also crucial factors determining frequency of health-related behavior in such patients.

    Full Text Available Bipolar disorder is characterized by recurrent attacks, significantly disrupts the functionality of a chronic mental disorder. Although there is growing number of studies on the neurobiological basis of the disorder, the pathophysiology has not yet been clearly understood. Structural and functional imaging techniques present a better understanding of the etiology of bipolar disorder and has contributed significantly to the development of the diagnostic approach. Recent developments in brain imaging modalities have let us learn more about the underlying abnormalities in neural systems of bipolar patients. Identification of objective biomarkers would help to determine the pathophysiology of bipolar disorder, a disorder which causes significant deterioration in neurocognitive and emotional areas.

    Full Text Available This study compared functional and physical collateral damage to a nerve when operating a Codman MALIS Bipolar Electrosurgical System CMC-III or a CO2 laser coupled to a laser, with correlation to an in vitro model of heating profiles created by the devices in thermochromic ink agarose. Functional damage of the rat sciatic nerve after operating the MALIS or CO2 laser at various power settings and proximities to the nerve was measured by electrically evoked nerve action potentials, and histology of the nerve was used to assess physical damage. Thermochromic ink dissolved in agarose was used to model the spatial and temporal profile of the collateral heating zone of the electrosurgical system and the laser ablation cone. We found that this laser can be operated at 2 W directly above the nerve with minimal damage, while power settings of 5 W and 10 W resulted in acute functional and physical nerve damage, correlating with the maximal heating cone in the thermochromic ink model. MALIS settings up to 40 (11 W did not result in major functional or physical nerve damage until the nerve was between the forceps tips, correlating with the hottest zone, localized discretely between the tips.

    This study had two objectives: (1) examine characteristics of aggression in children and adolescents diagnosed with bipolar disorder and (2) determine whether the CBCL pediatric bipolar disorder profile differentiated youngsters with bipolar disorder from youngsters with ADHD. Children and adolescents referred to a pediatric psychopharmacology clinic were systematically evaluated for psychopathology using a psychiatrist-administered diagnostic interview, parent- and teacher-report rating scales assessing the child's behavior, and child-completed self-report scales. In this sample, 27 children and adolescents were diagnosed with bipolar disorder and 249 youngsters were diagnosed with ADHD without co-occurring bipolar disorder. These two groups were compared to determine whether there were significant differences on various measures of psychopathology. Youngsters diagnosed with bipolar disorder were more verbally aggressive and exhibited higher levels of reactive aggression than youngsters with ADHD without co-occurring bipolar disorder. Youngsters with bipolar disorder also reported higher levels of depressive symptoms than youngsters with ADHD without bipolar disorder. The CBCL pediatric bipolar disorder profile did not accurately identify youngsters diagnosed with bipolar disorder. The present findings present a picture of manic youngsters as verbally aggressive and argumentative, who respond with anger when frustrated. Youngsters diagnosed with bipolar disorder and ADHD exhibited significant levels of impulsive behavior and attention problems, but youngsters with bipolar disorder also exhibited significant levels of aggressive behavior and dysphoric mood. Finally, the CBCL pediatric bipolar disorder profile did not accurately identify youngsters who were diagnosed with bipolar disorder. Copyright © 2010 Elsevier B.V. All rights reserved.

  5. Allostasis as a conceptual framework linking Bipolar Disorder and Addiction

    Full Text Available Bipolar disorders and addictions constitute reciprocal risk factors and are best considered under a unitary perspective. The concepts of allostasis and allostatic load may contribute to the understanding of the complex relationships between bipolar disorder and addictive behaviors. Allostasis entails the safeguarding of reward function stability by recruitment of changes in the reward and stress system neurocircuitry and it may help to elucidate neurobiological underpinnings of vulnerability to addiction in bipolar patients. Conceptualizing bipolar disorder as an illness involving the cumulative build-up of allostatic states, we hypothesize a progressive dysregulation of reward circuits clinically expressed as negative affective states (i.e. anhedonia. Such negative affective states may render bipolar disorder patients more vulnerable to drug addiction, fostering a very rapid transition from occasional drug use to addiction, through mechanisms of negative reinforcement. The resulting addictive behavior-related allostatic loads, in turn, may contribute to illness progression. This framework could have a heuristic value to enhance research on pathophysiology and treatment of bipolar disorder and addiction comorbidity.

While there are a multitude of psychopharmacologic agents are available for treatment of these illnesses, suboptimal response and significant adverse consequences limit their utility. Cariprazine is a new, novel antipsychotic medication with dopamine D2 and D3 partial agonist effects. Its safety and efficacy have been investigated in acute psychosis of schizophrenia, bipolar mania, bipolar depression, and unipolar depression. Efficacy has been demonstrated in schizophrenia and mania. It is unclear if cariprazine is effective in depression associated with unipolar or bipolar illness. Adverse consequences include extrapyramidal symptoms including akathisia, and various gastrointestinal symptoms. The US Food and Drug Administration (FDA has recently approved cariprazine. This review will provide clinicians with basic information regarding the research program of cariprazine.

    Religious and supernatural beliefs influence help seeking and treatment practices in bipolar disorder, but these are rarely explored by clinicians. This study aimed to understand religiousness, magico-religious beliefs, prevalence of religious and supernatural psychopathology and treatment practices among patients with bipolar disorder in euthymic state. A total of 185 patients of bipolar disorder currently in remission were assessed cross-sectionally for their clinical profile, current clinical status on the Hamilton Depression Rating Sscale (HDRS), Young Mania Rating Scale (YMRS) and the Global Assessment of Functioning (GAF). A semi structured instrument for magico-religious beliefs, aetiological models, treatment seeking and treatment practices was administered. More than a third of patients (37.8%) had psychopathology with either religious or supernatural content or both in their lifetime. Almost half (45.4%) the patients believed in a supernatural/religious aetiology for their illness. Among the specific causes, planetary influences (13.5%) and God's will (30.8%) were the most common supernatural and religious cause, respectively. Almost half (44.3%) of patients had first treatment contact with religious/supernatural treatment providers. More than 90% of patients reported belief in God, yet about 70% reported that their doctors did not ask them sufficient questions to understand their religiosity. Magico-religious beliefs are common in bipolar disorder and a large number of patients attribute these as aetiological factors for their illness. Consequently they tend to seek treatment from traditional practitioners prior to approaching medical practitioners and may continue treatment with them alongside medical management.

    Bipolar disorder and alcohol use disorder (AUD) have a high rate of comorbidity, more than 50% of individuals with bipolar disorder also receive a diagnosis of AUD in their lifetimes. Although both disorders are heritable, it is unclear if the same genetic factors mediate risk for bipolar disorder and AUD. We examined 733 Costa Rican individuals from 61 bipolar pedigrees. Based on a best-estimate process, 32% of the sample met criteria for bipolar disorder, 17% had a lifetime AUD diagnosis, 32% met criteria for lifetime nicotine dependence, and 21% had an anxiety disorder. AUD, nicotine dependence and anxiety disorders were relatively more common among individuals with bipolar disorder than in their non-bipolar relatives. All illnesses were shown to be heritable and bipolar disorder was genetically correlated with AUD, nicotine dependence and anxiety disorders. The genetic correlation between bipolar and AUD remained when controlling for anxiety, suggesting that unique genetic factors influence risk for comorbid bipolar and AUD independent of anxiety. Our findings provide evidence for shared genetic effects on bipolar disorder and AUD risk. Demonstrating that common genetic factors influence these independent diagnostic constructs could help to refine our diagnostic nosology. PMID:24321773

A neurocognitive profile characterized by widespread cognitive deficits across multiple domains in the context of substantial intellectual impairment, which appears to antedate illness onset, is a replicated finding in SZ. There is no specific neuropsychological signature that can facilitate the diagnostic differentiation of SZ and BD, notwithstanding, neuropsychological deficits appear more severe in SZ. The literature in this field has provided contradictory results due to methodological differences across studies. Meta-analytic techniques may offer an opportunity to synthesize findings and to control for potential sources of heterogeneity. Here, we performed a systematic review of meta-analyses of neuropsychological findings in SZ and BD. While there is no conclusive evidence for progressive cognitive deterioration in either SZ or BD, some findings point to more severe cognitive deficits in patients with early illness onset across both disorders. A compromised pattern of cognitive functioning in individuals at familiar and/or clinical risk to psychosis as well as in first-degree relatives of BD patients suggests that early neurodevelopmental factors may play a role in the emergence of cognitive deficits in both disorders.

    Emotional face recognition is impaired in bipolar disorder, but it is not clear whether this is specific for the illness. Here, we investigated how aging and bipolar disorder influence dynamic emotional face recognition. Twenty older adults, 16 bipolar patients, and 20 control subjects performed a dynamic affective facial recognition task and a subsequent rating task. Participants pressed a key as soon as they were able to discriminate whether the neutral face was assuming a happy or angry facial expression and then rated the intensity of each facial expression. Results showed that older adults recognized happy expressions faster, whereas bipolar patients recognized angry expressions faster. Furthermore, both groups rated emotional faces more intensely than did the control subjects. This study is one of the first to compare how aging and clinical conditions influence emotional facial recognition and underlines the need to consider the role of specific and common factors in emotional face recognition.

    2017-03-16

    Psychoeducation has become a common intervention within mental health settings. It aims to increase people's ability to manage a life with a long-term illness. For people with bipolar disorder, psychoeducation is one of a range of psychosocial interventions now considered part of contemporary mental health practice. It has taken on a 'common sense' status that results in little critique of psychoeducation practices. Using a published manual on psychoeducation and bipolar disorder as its data, Foucauldian discourse analysis was used in the present study for a critical perspective on psychoeducation in order to explore the taken-for-granted assumptions on which it is based. It identifies that the text produces three key subject positions for people with bipolar disorder. To practice self-management, a person must: (i) accept and recognize the authority of psychiatry to know them; (ii) come to see that they can moderate themselves; and (iii) see themselves as able to undertake a reflexive process of self-examination and change. These findings highlight the circular and discursive quality to the construct of insight that is central to how psychoeducation is practiced. Using Foucault's construct of pastoral power, it also draws attention to the asymmetrical nature of power relations between the clinician and the person with bipolar disorder. An effect of the use of medical discourse in psychoeducation is to limit its ability to work with ambivalence and contradiction. A critical approach to psychotherapy and education offers an alternate paradigm on which to basis psychoeducation practices.

    The comorbidity of bipolar disorder and eating disorders has not been studied in depth. In addition, clinical implications involved in the appearance of both disorders are very important. A systematic literature review of MEDLINE published up to September 2013 was performed, analyzing all the articles that studied the comorbidity of both conditions (bipolar disorder and eating disorders) and others research that studied the efficacy of pharmacological treatment and psychotherapy to improve these illnesses. In this review we found a high comorbidity of bipolar disorder and eating disorders, especially of bulimia nervosa and binge eating disorder. Studies show that lithium and topiramate are 2 of the more effective pharmacological agents in the treatment of both disorders. There are a lot of studies that show evidence of comorbidity of bipolar disorder and eating disorders. However, further research is needed on assessment and treatment when these conditions co-exist, as well as study into the biopsychological aspects to determine the comorbid aetiology.

    2008-02-01

    The increasing number and availability of various complementary and alternative medicines (CAM) has resulted in an exponentially growing utilization of these products for everything from minor aches and pains to the treatment of mental illness. Difficulties in treating mental illnesses in children, averseness to having children take psychiatric medications, and stigma all drive patients and their families to research alternative treatments. As a result, there has been an increased utilization of CAM in psychiatry, particularly for hard to treat conditions like pediatric BD. It is important for the health care providers to be aware of the alternative treatments by some of their patients. A review of studies investigating the utility of complementary and alternative medicines in bipolar patients was conducted and selected studies were included. Omega-3 fatty acids and lecithin/ choline have preliminary data indicating potential utility in the CAM treatment for bipolar disorder while S-adenosyl methionine (SAM-e) and inositol have some data supporting their efficacy in the treatment of depressive symptoms. Some data for CAM suggest they may be useful adjunctive treatments but only little data are available to support their use as stand-alone therapy. Thus, the conventional medicines remain the first choice in pediatric bipolar management. Healthcare providers need to routinely inquire about the utilization of these treatments by their patients and become familiar with the risks and benefits involved with their use in children.

    Bipolar disorder phenomenologically is a biphasic disorder of energy availability; increased in mania and decreased in depression. In consort, there is accumulating evidence indicating increased mitochondrial respiration and ATP production in bipolar mania which contrasts with decreased mitochondrial function in patients in the euthymic or depressive phase of the illness. Consequently, the central thesis of this paper is that bipolar disorder is due to a phasic dysregulation of mitochondrial biogenergetics. The elements responsible for this dysregulation may thus represent critical treatment targets for mood disorders, and are the subject of this paper. There are many potential mediators of mitochondrial function which collectively are implicated in bipolar disorder. Levels of oxidative stress, pro-inflammatory cytokines and intracellular calcium ions are all higher in bipolar mania than in the euthymic and depressive phases of the illness. Increased levels of calcium ions can partly account for increased oxidative phosphorylation via well documented pathways such as the modulation of the F1-FO elements of ATP synthase. Likewise, increased levels of oxidative stress and pro-inflammatory cytokines lead to the upregulation of AMPK, SIRT-1, SIRT-3 and NAD(+) which directly stimulate oxidative phosphorylation. Uric acid and melatonin are also differentially elevated in bipolar mania and both molecules stimulate the production of ATP. The pro-apoptotic, neurotoxic and mitotoxic effects of elevated glutamate, dopamine and GSK-3 in bipolar mania may be counterbalanced by higher basal levels and activity of p53, Bcl-2, PI3K and Akt in an environment of elevated uric acid and decreased BDNF. Details of these pathways are discussed as an explanatory model for the existence of increased ATP generation in mania. We also offer a model explaining the biphasic nature of mitochondrial respiration in bipolar disorder and the transition between mania and depression based on

The endorsement of the neuroinflammatory hypotheses of bipolar disorder requires the demonstration of causality, which requires longitudinal studies. We aimed to review the evidence for neuroinflammation as a pathogenic mechanism of the bipolar disorder. We carried out a hyper inclusive PubMed search using all appropriate neuroinflammation-related terms and crossed them with bipolar disorder-related terms. The search produced 310 articles and the number rose to 350 after adding articles from other search engines and reference lists. Twenty papers were included that appropriately tackled the issue of the presence (but not of its pathophysiological role of neuroinflammation in bipolar disorder. Of these, 15 were postmortem and 5 were carried out in living humans. Most articles were consistent with the presence of neuroinflammation in bipolar disorder, but factors such as treatment may mask it. All studies were cross-sectional, preventing causality to be inferred. Thus, no inference can be currently made about the role of neuroinflammation in bipolar disorder, but a link is likely. The issue remains little investigated, despite an excess of reviews on this topic.

    Many family characteristics were reported to increase the risk of bipolar disorder (BPD). The development of BPD may be mediated through different pathways, involving diverse risk factor profiles. We evaluated the associations of family characteristics to build influential causal-pie models to estimate their contributions on the risk of developing BPD at the population level. We recruited 329 clinically diagnosed BPD patients and 202 healthy controls to collect information in parental psychopathology, parent-child relationship, and conflict within family. Other than logistic regression models, we applied causal-pie models to identify pathways involved with different family factors for BPD. The risk of BPD was significantly increased with parental depression, neurosis, anxiety, paternal substance use problems, and poor relationship with parents. Having a depressed mother further predicted early onset of BPD. Additionally, a greater risk for BPD was observed with higher numbers of paternal/maternal psychopathologies. Three significant risk profiles were identified for BPD, including paternal substance use problems (73.0%), maternal depression (17.6%), and through poor relationship with parents and conflict within the family (6.3%). Our findings demonstrate that different aspects of family characteristics elicit negative impacts on bipolar illness, which can be utilized to target specific factors to design and employ efficient intervention programs.

In the last few years, new efforts to better characterize the socio-demographic and clinical profiles of BD type I vs II have been documented by several reports, with novel and insightful findings in the field. The present multicenter study aimed to provide a comprehensive and reliable representation of the Italian reality, through the analysis of the largest national sample of bipolar patients collected so far. A total of 1500 patients (BD I n = 963 and BD II n = 537) from different psychiatric departments, participating in the Italian Chapter of the "International Society of Bipolar Disorders" (ISBD), were assessed and divided into two groups on the basis of their diagnostic subtype, and different socio-demographic and clinical variables were compared between the two subgroups. Chi-squared tests for categorical variables and t tests for continuous variables were performed for group comparison. Furthermore, a multivariable logistic regression was performed, considering diagnostic bipolar subtype (type I or II) as dependent variable, and socio-demographic/clinical characteristics as independent variables. BD I vs II patients showed an overall less favorable socio-demographic and clinical profile. In addition, the multivariable logistic regression showed that BD II vs BD I was predicted by the absence of lifetime suicide attempts (OR = 1.58, p = 0.01), a later age of diagnosis (OR = 1.03, p < 0.01), less hypomanic episodes in the last year (OR = 2.29, p < 0.0001) and absence of psycho-educational interventions in the last year (OR = 0.51, p < 0.01). BD I and II patients were found to significantly differ in relation to specific clinical variables, which should be considered within updated diagnostic-therapeutic algorithms.

    The majority of patients with bipolar disorder spend a lot of time in depressive episodes that impose a great burden on patients, caregivers, and society and accounts for the largest part of the morbidity-mortality of the illness. Lurasidone is an atypical antipsychotic with a potent binding affinity as antagonist for D2, 5-HT2A, 5-HT7, and partial agonist at 5-HT1A receptors. Affinity for other receptors as H1 and muscarinic were negligible. Lurasidone was approved in 2010 for the treatment of schizophrenia and recently, 2013, for bipolar depression in monotherapy and an adjunct to lithium or valproate. Clinical trials have established that lurasidone adjuvant to lithium or valproate has more efficacy than the placebo and is associated with minimal weight gain and no clinically meaningful alterations in glucose, lipids, or the QT interval. Additional studies are desirable to know the clinical profile of lurasidone in long-term treatment, in patients with bipolar II disorders, and versus other antipsychotic agents.

BD is associated with many limitations in personal and interpersonal functioning and restricts the patients’ ability to use their potential capabilities fully. Bipolar patients long to live meaningful lives, but this goal is hard to achieve for those with poor insight. With progress and humanization of society, the issue of patients’ needs became an important topic. The objective of the paper is to provide the up-to-date data on the unmet needs of BD patients and their caregivers. Methods: A systematic computerized examination of MEDLINE publications from 1970 to 2015, via the keywords “bipolar disorder”, “mania”, “bipolar depression”, and “unmet needs”, was performed. Results: Patients’ needs may differ in various stages of the disorder and may have different origin and goals. Thus, we divided them into five groups relating to their nature: those connected with symptoms, treatment, quality of life, family, and pharmacotherapy. We suggested several implications of these needs for pharmacotherapy and psychotherapy. Conclusion: Trying to follow patients’ needs may be a crucial point in the treatment of BD patients. However, many needs remain unmet due to both medical and social factors. Keywords: bipolar disorder, unmet needs, stigma, treatment, medication, quality of life, family, psychotherapy

  6. Memantine: New prospective in bipolar disorder treatment

    We review preclinical and clinical evidences strongly suggesting that memantine, an old drug currently approved for Alzheimer’s dementia, is an effective treatment for acute mania and for the prevention of manic/hypomanic and depressive recurrences of manic-depressive illness. Lithium remains the first line for the treatment and prophylaxis of bipolar disorders, but currently available treatment alternatives for lithium resistant patients are of limited and/or questionable efficacy. Thus, research and development of more effective mood stabilizer drugs is a leading challenge for modern psychopharmacology. We have demonstrated that 21 d administration of imipramine causes a behavioural syndrome similar to a cycle of bipolar disorder, i.e., a mania followed by a depression, in rats. Indeed, such treatment causes a behavioural supersensitivity to dopamine D2 receptor agonists associated with an increase sexual activity and aggressivity (mania). The dopamine receptor sensitization is followed, after imipramine discontinuation, by an opposite phenomenon (dopamine receptor desensitization) and an increased immobility time (depression) in the forced swimming test of depression. Memantine blocks the development of the supersensitivity and the ensuing desensitization associated with the depressive like behavior. On the basis of these observations we have suggested the use of memantine in the treatment of mania and in the prophylaxis of bipolar disorders. To test this hypothesis we performed several naturalistic studies that showed an acute antimanic effect and a long-lasting and progressive mood-stabilizing action (at least 3 years), without clinically relevant side effects. To confirm the observations of our naturalistic trials we are now performing a randomized controlled clinical trial. Finally we described the studies reporting the efficacy of memantine in manic-like symptoms occurring in psychiatric disorders other than bipolar. Limitations: A randomized controlled

  7. Cognitive enhancing agents in schizophrenia and bipolar disorder.

    Cognitive dysfunction is a core feature of schizophrenia and is also present in bipolar disorder (BD). Whereas decreased intelligence precedes the onset of psychosis in schizophrenia and remains relatively stable thereafter; high intelligence is a risk factor for bipolar illness but cognitive function decreases after onset of symptoms. While in schizophrenia, many studies have been conducted on the development of cognitive enhancing agents; in BD such studies are almost non-existent. This review focuses on the pharmacological agents with putative effects on cognition in both schizophrenia and bipolar illness; specifically agents targeting the dopaminergic, cholinergic and glutamatergic neurotransmitter pathways in schizophrenia and the cognitive effects of lithium, anticonvulsants and antipsychotics in BD. In the final analysis we conclude that cognitive enhancing agents have not yet been produced convincingly for schizophrenia and have hardly been studied in BD. Importantly, studies should focus on other phases of the illness. To be able to treat cognitive deficits effectively in schizophrenia, patients in the very early stages of the illness, or even before - in the ultra-high risk stages - should be targeted. In contrast, cognitive deficits occur later in BD, and therefore drugs should be tested in BD after the onset of illness. Hopefully, we will then find effective drugs for the incapacitating effects of cognitive deficits in these patients.

    Full Text Available Stigma is a serious impediment to the well-being of those who experience it. Many family- caregivers are challenged by the stereotypes and prejudice that result from misconceptions about bipolar disorder.The purpose of this study was to explore the stigma experienced by family caregivers of patients with bipolar disorder.This was a qualitative and phenomenological study. In this study, we selected the family caregivers of patients with bipolar disorder in a psychiatric hospital (Iran using purposive sampling in 2011. By reaching data saturation, the number of participant was 12. Data were gathered through in-depth interviews and analyzed by the "Collaizi" method.Stigma was a pervasive concern to almost all participants. Family caregivers of patients with Bipolar disorders reported feelings and experiences of stigma and were most affected by them. Analysis of the interviews revealed 3 themes: Negative judgment, Shame, Stigmatization and Social Isolation.For a person with bipolar disorder, this illness is associated with the following problems: worse recovery, difficulty accessing health services, receiving poor treatment and support, and difficulty gaining community acceptance. Rejection of people with mental illness might also affect their family caregivers at various levels.

    2012-01-01

    Full Text Available Previous research on functional outcome in bipolar disorder (BD has uncovered various factors that exacerbate psychosocial disability over the course of illness, including genetics, illness severity, stress, anxiety, and cognitive impairment. This paper presents an integrated view of these findings that accounts for the precipitous decline in psychosocial functioning after illness onset. The proposed model highlights a number of reciprocal pathways among previously studied factors that trap people in a powerful cycle of ailing forces. The paper discusses implications to patient care as well as the larger social changes required for shifting the functional trajectory of people with BD from psychosocial decline to growth.

    Eighty-nine bipolar I patients were given a structured interview, the Schedule for Affective Disorders and Schizophrenia. Those who had experienced delusions or hallucinations at some time during the course of their illness were designated "psychotic," and those who had not were designated "nonpsychotic." The two groups were compared with regard to a number of outcome variables as well as age, age at first treatment, and duration of illness. The psychotic group had significantly poorer outcome in terms of social functioning. Although age, age at first treatment, and duration of illness distinguished between the two groups of patients, statistical analyses indicated that these variables did not account for differences in social outcome.

    Bipolar disorder among pregnant women has deleterious effects on birth and child outcomes and is currently under-detected, not addressed effectively, or exacerbated through inappropriate treatment. The goal of this study was to identify perspectives of pregnant and postpartum women with bipolar disorder on barriers and facilitators to psychiatric treatment during pregnancy. In-depth interviews were conducted with pregnant and postpartum women who scored ≥ 10 on the Edinburgh Postnatal Depression Scale and met DSM-IV criteria for bipolar disorder I, II or not otherwise specified using the Mini International Neuropsychiatric Interview version 5.0. Interviews were transcribed, and resulting data were analyzed using a grounded theory approach to identify barriers and facilitators to bipolar disorder treatment access in pregnancy. Participant identified barriers included perception that psychiatric providers lack training and experience in the treatment of psychiatric illness during pregnancy, are reluctant to treat bipolar disorder among pregnant women, and believe that pharmacotherapy is not needed for psychiatric illness during pregnancy. Facilitators included participants' perception that providers' acknowledge risks associated with untreated or undertreated psychiatric illness during pregnancy and provide psycho-education about the risks, benefits and alternatives to pharmacotherapy. Psychiatric providers are critically important to the treatment of bipolar disorder and need knowledge and skills necessary to provide care during the perinatal period. Advancing psychiatric providers' knowledge/skills may improve access to pharmacotherapy for pregnant women with bipolar disorder.

    Childhood adverse events are risk factors for later bipolar disorder. We quantified the risks for a later diagnosis of bipolar disorder after exposure to adverse life events in children with and without parental psychopathology. This register-based population cohort study included all persons born in Denmark from 1980 to 1998 (980 554 persons). Adversities before age 15 years were: familial disruption; parental somatic illness; any parental psychopathology; parental labour market exclusion; parental imprisonment; placement in out-of-home care; and parental natural and unnatural death. We calculated risk estimates of each of these eight life events as single exposure and risk estimates for exposure to multiple life events. Main outcome variable was a diagnosis of bipolar disorder after the age of 15 years, analysed with Cox proportional hazard regression. Single exposure to most of the investigated adversities were associated with increased risk for bipolar disorder, exceptions were parental somatic illness and parental natural death. By far the strongest risk factor for bipolar disorder in our study was any mental disorder in the parent (hazard ratio 3.53; 95% confidence interval 2.73-4.53) and the additional effects of life events on bipolar risk were limited. An effect of early adverse life events on bipolar risk later in life was mainly observed in children without parental psychopathology. Our findings do not exclude early-life events as possible risk factors, but challenge the concept of adversities as important independent determinants of bipolar disorder in genetically vulnerable individuals.

    Rates of misdiagnosis between major depressive disorder and bipolar disorder have been reported to be substantial, and the consequence of such misdiagnosis is likely to be a delay in achieving effective control of symptoms, in some cases spanning many years. Particularly in the midst of a depressive episode, or early in the illness course, it may be challenging to distinguish the 2 mood disorders purely on the basis of cross-sectional features. To date, no useful biological markers have been reliably shown to distinguish between bipolar disorder and major depressive disorder.

    Full Text Available This paper consists of a case history and an overview of the relationship, aetiology, and treatment of comorbid bipolar disorder migraine patients. A MEDLINE literature search was used. Terms for the search were bipolar disorder bipolar depression, mania, migraine, mood stabilizer. Bipolar disorder and migraine cooccur at a relatively high rate. Bipolar II patients seem to have a higher risk of comorbid migraine than bipolar I patients have. The literature on the common roots of migraine and bipolar disorder, including both genetic and neuropathological approaches, is broadly discussed. Moreover, bipolar disorder and migraine are often combined with a variety of other affective disorders, and, furthermore, behavioural factors also play a role in the origin and course of the diseases. Approach to treatment options is also difficult. Several papers point out possible remedies, for example, valproate, topiramate, which acts on both diseases, but no first-choice treatments have been agreed upon yet.

    1992-01-01

    An apparatus [10] is disclosed for a lightweight bipolar battery of the end-plate cell stack design. Current flow through a bipolar cell stack [12] is collected by a pair of copper end-plates [16a,16b] and transferred edgewise out of the battery by a pair of lightweight, low resistance copper terminals [28a,28b]. The copper terminals parallel the surface of a corresponding copper end-plate [16a,16b] to maximize battery throughput. The bipolar cell stack [12], copper end-plates [16a,16b] and copper terminals [28a,28b] are rigidly sandwiched between a pair of nonconductive rigid end-plates [20] having a lightweight fiber honeycomb core which eliminates distortion of individual plates within the bipolar cell stack due to internal pressures. Insulating foam [30] is injected into the fiber honeycomb core to reduce heat transfer into and out of the bipolar cell stack and to maintain uniform cell performance. A sealed battery enclosure [ 22] exposes a pair of terminal ends [26a,26b] for connection with an external circuit.

    Multi-layer perceptron (MLP) neural network belongs to multi-layer feedforward neural network, and has the ability and characteristics of high intelligence. It can realize the complex nonlinear mapping by its own learning through the network. Bipolar disorder is a serious mental illness with high recurrence rate, high self-harm rate and high suicide rate. Most of the onset of the bipolar disorder starts with depressive episode, which can be easily misdiagnosed as unipolar depression and lead to a delayed treatment so as to influence the prognosis. The early identifica- tion of bipolar disorder is of great importance for patients with bipolar disorder. Due to the fact that the process of early identification of bipolar disorder is nonlinear, we in this paper discuss the MLP neural network application in early identification of bipolar disorder. This study covered 250 cases, including 143 cases with recurrent depression and 107 cases with bipolar disorder, and clinical features were statistically analyzed between the two groups. A total of 42 variables with significant differences were screened as the input variables of the neural network. Part of the samples were randomly selected as the learning sample, and the other as the test sample. By choosing different neu- ral network structures, all results of the identification of bipolar disorder were relatively good, which showed that MLP neural network could be used in the early identification of bipolar disorder.

    Treatment innovation for bipolar disorder has been hampered by a lack of techniques to capture a hallmark symptom: ongoing mood instability. Mood swings persist during remission from acute mood episodes and impair daily functioning. The last significant treatment advance remains Lithium (in the 1970s), which aids only the minority of patients. There is no accepted way to establish proof of concept for a new mood-stabilizing treatment. We suggest that combining insights from mood measurement with applied mathematics may provide a step change: repeated daily mood measurement (depression) over a short time frame (1 month) can create individual bipolar mood instability profiles. A time-series approach allows comparison of mood instability pre- and post-treatment. We test a new imagery-focused cognitive therapy treatment approach (MAPP; Mood Action Psychology Programme) targeting a driver of mood instability, and apply these measurement methods in a non-concurrent multiple baseline design case series of 14 patients with bipolar disorder. Weekly mood monitoring and treatment target data improved for the whole sample combined. Time-series analyses of daily mood data, sampled remotely (mobile phone/Internet) for 28 days pre- and post-treatment, demonstrated improvements in individuals' mood stability for 11 of 14 patients. Thus the findings offer preliminary support for a new imagery-focused treatment approach. They also indicate a step in treatment innovation without the requirement for trials in illness episodes or relapse prevention. Importantly, daily measurement offers a description of mood instability at the individual patient level in a clinically meaningful time frame. This costly, chronic and disabling mental illness demands innovation in both treatment approaches (whether pharmacological or psychological) and measurement tool: this work indicates that daily measurements can be used to detect improvement in individual mood stability for treatment innovation (MAPP).

    To explore to what extent the lay public knows that the term bipolar disorder denotes a mental disorder. In January 2005, a telephone survey was conducted among a random sample of the German population (n = 1006). Out of four options given, respondents were asked to select the one they considered to be the correct explanation of what is meant by bipolar disorder. Most of the respondents (61%) believed that bipolar disorder is just another term for the melting of the polar ice caps, only 4.6 % associated it with mental illness. The question arises as to whether it makes sense to use a diagnosis which the lay public associates with everything but a mental illness. Since it is impossible to erase the term bipolar disorder from the psychiatric terminology, it seems necessary to increasingly propagate this term among the lay public.

    Tests of lateral asymmetry in hand preference and superiority in thumb opposition rotation (opposing the thumb's pulp surface to that of the little finger) have been applied to bipolar and unipolar affective patients in an attempt to evaluate the effectiveness of these tests in differentiating the bipolar and unipolar patient populations. Two comparison samples were also tested: nonpsychotic central nervous system (CNS) disease patients, and normal controls. The normals divided almost evenly into pure dominance (e.g., right-handed, and superior right thumb opposition) and cross-dominance (e.g., right-handed, but superior left thumb opposition). All but one of the CNS disease patients were cross-dominant; the bipolars were predominantly pure dominant; while the unipolars, in contrast to the pure dominant bipolars, were in the majority cross-dominant. This result is consistent with the view that there are two types of affective disorder, bipolar manic-depressive and unipolar depressive illness.

    Schema therapy (ST) is an integrative form of psychotherapy developed for complex, chronic psychological disorders with a characterlogical underpinning. Bipolar disorder is just such a disorder--complex and often comorbid, with demonstrated stable cognitive and personality features that complicate the course of illness. This article presents the reasons justifying the application of ST to bipolar disorder and proposes a treatment rationale and future directions for treatment and research. If well adapted to the characteristics of bipolar disorder, ST might prove to be an effective adjunctive psychotherapy option that attenuates emotional reactivity, reduces symptoms and improves quality of life.

  10. Cognitive neuroscience and brain imaging in bipolar disorder.

    Science.gov (United States)

    Clark, Luke; Sahakian, Barbara J

    2008-01-01

    Bipolar disorder is characterized by a combination of state-related changes in psychological function that are restricted to illness episodes, coupled with trait-related changes that persist through periods of remission, irrespective of symptom status. This article reviews studies that have investigated the brain systems involved in these state- and trait-related changes, using two techniques: (i) indirect measures of neurocognitive function, and (ii) direct neuroimaging measures of brain function during performance of a cognitive task. Studies of neurocognitive function in bipolar disorder indicate deficits in three core domains: attention, executive function, and emotional processing. Functional imaging studies implicate pathophysiology in distributed neural circuitry that includes the prefrontal and anterior cingulate cortices, as well as subcortical limbic structures including the amygdala and the ventral striatum. Whilst there have been clear advances in our understanding of brain changes in bipolar disorder, there are limited data in bipolar depression, and there is limited understanding of the influence of clinical variables including medication status, illness severity, and specific symptom dimensions.

    Pediatric bipolar disorder, once considered rare, has reportedly increased in incidence over the past 10 years. There is significant debate about the phenomenology, diagnosis and treatment of this illness. The diagnostic assessment of children with severe mood and behavioural disturbance is of considerable public health importance as the ultimate diagnosis can have significant treatment implications and can impact the level of stigma experienced by children and their families. The purposes of this paper are to: 1) review current issues in the phenomenology and diagnostic assessment of bipolar disorder in children and adolescents; 2) review recent research suggesting that youths with a chronic course of illness should be considered a separate group from those with an episodic course; and 3) offer suggestions for future studies to address the various phenomenological controversies.

    Full Text Available There is growing evidence showing that bipolar disorder is associated with persistent cognitive deficits. However, the exact meaning and impact of cognitive deficits in bipolar disorder is still not entirely known, even though they have been associated with poor psychosocial functioning. This study aims to summarize cognitive and psychosocial functioning findings of remitted bipolar patients. We conducted an extensive Medline search of the published English literature for the period January 2000– March 2014 using a variety of search terms to find relevant articles. Bibliographies of retrieved papers were further analysed for publications of interest. Our results showed that: (1 all mood states of bipolar disorder are associated with cognitive impairment. However, the euthymic state is associated with less impairment than the other states; (2 there is a strong association between clinical factors (i.e, duration of illness, number of episodes, residual mood symptoms, comorbidities and cognitive impairment in euthymic bipolar patients, although these factors do not account fully for these deficits; (3 cognitive deficits, in particular, verbal learning and executive dysfunctions may contribute to poor functioning. In conclusion, our review suggests that cognitive deficits are strongly associated with mood episodes; such deficits persist, in lower degree, during remission. Impairment on cognitive performance may explain, in part, poor long–term functioning in remitted bipolar patients. It highlights that psychosocial interventions in combination with pharmacotherapy should be considered to improve cognition and enhance the level of functioning. Therefore, studies assessing the efficacy of novel strategies focused on cognitive and functional status are an important area of future investigation in bipolar disorder.

    Psychotic bipolar depressive episodes remain remarkably understudied despite being common and having a significant impact on bipolar disorder. The aim of this study is to identify the characteristics of depressed bipolar patients with current psychosis compared to those without psychosis. We used baseline data of a comparative effectiveness study of lithium and quetiapine for bipolar disorder (the Bipolar CHOICE study) to compare demographic, clinical, and functioning variables between those with and without psychotic symptoms. Of the 482 participants, 303 (62.9%) were eligible for the present study by meeting DSM-IV criteria for an acute bipolar depressive episode. Univariate analyses were conducted first, and then included in a model controlling for symptom severity. The sample was composed mostly of women (60.7%) and the mean age was 39.5±12.1 years. Psychosis was present in 10.6% (n=32) of the depressed patients. Psychotic patients had less education, lower income, and were more frequently single and unemployed. Psychosis was also associated with a more severe depressive episode, higher suicidality, more comorbid conditions and worse functioning. Most group differences disappeared when controlling for depression severity. Only outpatients were included and the presence of psychosis in previous episodes was not assessed. Psychosis during bipolar depressive episodes is present even in an outpatient sample. Psychotic, depressed patients have worse illness outcomes, but future research is necessary to confirm if these outcomes are only associated with the severity of the disorder or if some of them are independent of it.

    The child behavior checklist-Juvenile bipolar disorder phenotype (CBCL-JBD) has been proposed as a distinct profile specific to children and adolescents who have been diagnosed with bipolar disorder. The objective of this study was to examine whether bipolar disorder youth with depression exhibit the "CBCL-Juvenile bipolar disorder phenotype." Thirty-two adolescents, ages 12-18 years, with a depressive episode associated with bipolar I disorder were recruited, and their primary caregivers completed the CBCL. Only the internalizing subscale (mean=70.2, SD=9.7) and total score (mean=71.5, SD=8.9) reached clinical significance (>70). Moreover, the CBCL-JBD profile scores of our subjects (204.6, SD=27.5) did not reach clinical significance (>210). Our subjects differed demographically from those in studies that have confirmed the CBCL-Juvenile bipolar disorder phenotype with regards to sex, age and ADHD comorbidity, thus limiting the interpretability of our comparisons with other studies. Furthermore, our investigation involved a small sample size and did not include a control group, which should be addressed in future studies. The results of our study suggest that the CBCL-JBD profile is not characteristic of depressed youth with bipolar disorder. Better assessment tools for making an accurate and efficient diagnosis of bipolar disorder are needed so that appropriate treatment can be implemented and significant morbidity and mortality are minimized.

    Bipolar affective disorder is one of most injurious psychiatric diseases, not, rarely leading patient for suicide, and its prevalence keeps increasing worldwide, notably on low and, middle-income countries. For children living in northeast Brazil, extreme social conditions constitute, an environment of special vulnerability. Here we show that bipolar disorder incidence, between children and adolescents in this Brazilian region increased 34.2% from 2005 to 2014 and, in, the same area and age group, deaths provoked by self-caused injuries also became progressively, greater. According to DATASUS, the Brazilian national databank for public health, information, in the last five years, we observed an increase of Bipolar Disorder incidence rates under, 19 year-old of about 34.2% in the northeast region of Brazil, while the increase for Brazilian general, population was 12.4%. If considered only patients under 10, this number is even greater, of 47.2%. Content of Table 2 shows this disproportion, while comparing the advance of bipolar disorder, morbidity indices nationwide and worldwide. Children living in Brazil's northeast, region are in a condition of extreme social disadvantage, what can be determinant for the recent and, sequential increase of bipolar disorder prevalence and the mortality in this age-group due to suicide, one of possible reflections of untreated mood disorders. For protecting these children is important to, identify the factors which prevent these illnesses and promote resilience for these young people. Copyright © 2014 Elsevier B.V. All rights reserved.

    The aim of this study was to investigate the impact of self-rated stigma and functioning in patients with bipolar disorder in South Brazil. This is a cross-sectional study. Sixty participants with bipolar disorder were recruited from an outpatient Bipolar Disorder Program. Experiences with and impact of perceived stigma were evaluated using the Inventory of Stigmatizing Experiences. Functional impairment was assessed with the Functioning Assessment Short Test (FAST). Higher scores of self-perceived stigma were correlated with higher FAST scores, indicating more disability. After linear correlation analysis, current depressive symptoms, age at onset of treatment, age at diagnosis and functioning were correlated with self-perceived stigma. The study demonstrated a correlation between stigma and poor functioning in bipolar disorder. Perceived stigma is really important to individuals with bipolar disorder, both to how they experience their illness and to its results on functioning. Potential consequences of such results for mental health care professionals are discussed. Differential clinical features, sociocultural factors and the sample size limit the generalization of the present findings. © 2011 Blackwell Publishing.

    Psychiatric disorders are highly heritable, and in many individuals likely arise from the combined effects of genes and the environment. A substantial body of evidence points towards DISC1 being one of the genes that influence risk of schizophrenia, bipolar disorder and depression, and functional studies of DISC1 consequently have the potential to reveal much about the pathways that lead to major mental illness. Here, we review the evidence that DISC1 influences disease risk through effects u...

    Full Text Available OBJECTIVES: The objective of this article is to discuss the rationale/background for early intervention in bipolar disorder. METHOD: Narrative review. RESULTS: There are often significant delays before the diagnosis of bipolar disorder is made and effective management initiated. Growing evidence from both preclinical and clinical literature points to a clear need for improved early identification and early intervention in bipolar disorder. Increasing efforts are being applied to the identification of those at high risk of onset of bipolar disorder. It is hoped that identification of an early prodrome of illness will allow preventative measures to be taken. CONCLUSIONS: There is a clear rationale for improved early identification and early intervention in bipolar disorder.OBJETIVOS: O objetivo do artigo é discutir os fundamentos para a intervenção precoce no transtorno bipolar. MÉTODO: Revisão narrativa. RESULTADOS: Frequentemente existe um atraso significativo com relação ao momento em que o transtorno bipolar é detectado e o início do tratamento. Evidências crescentes oriundas de estudos pré-clínicos e clínicos apontam para a clara necessidade de melhorar a detecção e o tratamento precoces no transtorno bipolar. Esforços também tem sido direcionados para a identificação de indivíduos em alto risco. Espera-se que a identificação do pródromo do transtorno bipolar permita a instauração de medidas preventivas.

    In an attempt to improve the classification of Bipolar II disorders, we have examined a consecutive series of 687 primary major depressives: 5.1% gave a past history of mania (Bipolar I), 13.7% met our operational criteria for hypomania (Bipolar II), and the remaining 81.2% were provisionally categorized as 'unipolar.' Although Bipolar II was in some respects intermediate between Bipolar I and Unipolar, gender, familial bipolar history, age at onset and course characteristics generally supported its closer kinship to bipolar illness. Seventy one of the unipolars (10.3% of the total series) further met our operational criteria for hyperthymic temperament (U-HT), leaving behind a purer unipolar group of 487 major depressives. With respect to the proportion having male gender and bipolar family history, U-HT was similar to Bipolar I and II, and all three differed significantly from pure unipolar; as for age at onset, number of episodes and related indices of course, BI and BII were similar, and U-HT was closer to pure unipolar. These findings suggest that major depressive episodes arising from a hyperthymic temperament (constituting 12.4% of the 'unipolar' universe by conventional definition) are 'genotypically' closer to Bipolar II defined by hypomania, and course-wise similar to other unipolars.

    There is little evidence supporting the management of depression in schizoaffective disorder, bipolar type. Managing bipolar depression can be a daunting task for clinicians. Most bipolar patients spend 80% of their time in the depressive phase of illness. In contrast with full-blown mania, patients and family frequently fail to recognize bipolar depression, which may interfere with early diagnosis and treatment. With only a few medications approved for bipolar depression, treatment becomes very challenging. There is evidence to support that schizoaffective depression has a worse outcome than psychotic depression and nonpsychotic depression. We report a patient with schizoaffective disorder, bipolar type with severe depression who responded to an adequate level of lithium and subsequently, on a combination of lithium and quetiapine. Finally, we emphasize the importance of measurement-based care. To our knowledge, this is the first case report focusing on the management of depression in schizoaffective disorder, bipolar type.

    It is well recognized that mood disorders and epilepsy commonly co-occur. Despite this, our knowledge regarding the relationship between epilepsy and bipolar disorder is limited. Several shared features between the two disorders, such as their episodic nature and potential to run a chronic course, and the efficacy of some antiepileptic medications in the prophylaxis of both disorders, are often cited as evidence of possible shared underlying pathophysiology. The present paper aims to review the bidirectional associations between epilepsy and bipolar disorder, with a focus on epidemiological links, evidence for shared etiology, and the impact of these disorders on both the individual and wider society. Better recognition and understanding of these two complex disorders, along with an integrated clinical approach, are crucial for improved evaluation and management of comorbid epilepsy and mood disorders.

  7. Molecules in Bipolar Outflows

    CERN Document Server

    Tafalla, Mario

    2012-01-01

    Bipolar outflows constitute some of the best laboratories to study shock chemistry in the interstellar medium. A number of molecular species have their abundance enhanced by several orders of magnitude in the outflow gas, likely as a combined result of dust mantle disruption and high temperature gas chemistry, and therefore become sensitive indicators of the physical changes taking place in the shock. Identifying these species and understanding their chemical behavior is therefore of high interest both to chemical studies and to our understanding of the star-formation process. Here we review some of the recent progress in the study of the molecular composition of bipolar outflows, with emphasis in the tracers most relevant for shock chemistry. As we discuss, there has been rapid progress both in characterizing the molecular composition of certain outflows as well as in modeling the chemical processes likely involved. However, a number of limitations still affect our understanding of outflow chemistry. These i...

    Full Text Available Diferenças sexuais, descritas em vários transtornos psiquiátricos, também parecem estar presentes no transtorno afetivo bipolar (TAB. A prevalência do TAB tipo I se distribui igualmente entre mulheres e homens. Mulheres parecem estar sujeitas a um risco maior de ciclagem rápida e mania mista, condições que fariam do TAB um transtorno com curso mais prejudicial no sexo feminino. Uma diátese depressiva mais marcante, uso excessivo de antidepressivos e diferenças hormonais surgem como hipóteses para explicar essas diferenças fenomenológicas, apesar das quais, mulheres e homens parecem responder igualmente ao tratamento medicamentoso. A indicação de anticonvulsivantes como primeira escolha em mulheres é controversa, a não ser para o tratamento da mania mista e, talvez, da ciclagem rápida. O tratamento do TAB na gravidez deve levar em conta tanto os riscos de exposição aos medicamentos quanto à doença materna. A profilaxia do TAB no puerpério está fortemente indicada em decorrência do grande risco de recorrência da doença nesse período. Embora, de modo geral, as medicações psicotrópicas estejam contra-indicadas durante a amamentação, entre os estabilizadores do humor, a carbamazepina e o valproato são mais seguros do que o lítio. Mais estudos são necessários para a confirmação das diferenças de curso do TAB entre mulheres e homens e a investigação de possíveis diferenças na efetividade dos tratamentos.Gender differences, described in several psychiatric disorders, seem to be also present in bipolar disorder (BD. The prevalence of bipolar I disorder is equally distributed between women and men.

    The relationship between creativity and bipolar disorder has been an intriguing topic since ancient times. Early studies focused on describing characteristics of creative people. From the last quarter of the twentieth century, researchers began to focus on the relationship between mood disorders and creativity. Initially, the studies were based on biographical texts and the obtained results indicated a relationship between these two concepts. The limitations of the retrospective studies led the researchers to develop systematic investigations into this area. The systematic studies that have focused on artistic creativity have examined both the prevalence of mood disorders and the creative process. In addition, a group of researchers addressed the relationship in terms of affective temperaments. Through the end of the 90's, the scope of creativity was widened and the notion of everyday creativity was proposed. The emergence of this notion led researchers to investigate the associations of the creative process in ordinary (non-artist) individuals. In this review, the descriptions of creativity and creative process are mentioned. Also, the creative process is addressed with regards to bipolar disorder. Then, the relationship between creativity and bipolar disorder are evaluated in terms of aforementioned studies (biographical, systematic, psychobiographical, affective temperaments). In addition, a new model, the "Shared Vulnerability Model" which was developed to explain the relationship between creativity and psychopathology is introduced. Finally, the methodological limitations and the suggestions for resolving these limitations are included.

    Full Text Available Comorbid endocrine and cardiovascular situations with bipolar disorder usually result from the bipolar disorder itself or as a consequence of its treatment. With habits and lifestyle, genetic tendency and side effects, this situation is becoming more striking. Subpopulations of bipolar disorders patients should be considered at high risk for diabetes mellitus. The prevalence of diabetes mellitus in bipolar disorder may be three times greater than in the general population. Comorbidity of diabetes causes a pathophysiological overlapping in the neurobiological webs of bipolar cases. Signal mechanisms of glycocorticoid/insulin and immunoinflammatory effector systems are junction points that point out the pathophysiology between bipolar disorder and general medical cases susceptible to stress. Glycogen synthetase kinase (GSK-3 is a serine/treonine kinase and inhibits the transport of glucose stimulated by insulin. It is affected in diabetes, cancer, inflammation, Alzheimer disease and bipolar disorder. Hypoglycemic effect of lithium occurs via inhibiting glycogen synthetase kinase. When comorbid with diabetes, the other disease -for example bipolar disorder, especially during its acute manic episodes-, causes a serious situation that presents its influences for a lifetime. Choosing pharmacological treatment and treatment adherence are another important interrelated areas. The aim of this article is to discuss and review the etiological, clinical and therapeutic properties of diabetes mellitus and bipolar disorder comorbidity.

    Illness staging is widely utilized in several medical disciplines to help predict course or prognosis, and optimize treatment. Staging models in psychiatry in general, and bipolar disorder in particular, depend on the premise that psychopathology moves along a predictable path: an at-risk or latency stage, a prodrome progressing to a first clinical threshold episode, and one or more recurrences with the potential to revert or progress to late or end-stage manifestations. The utility and validity of a staging model for bipolar disorder depend on its linking to clinical outcome, treatment response and neurobiological measures. These include progressive biochemical, neuroimaging and cognitive changes, and potentially stage-specific differences in response to pharmacological and psychosocial treatments. Mechanistically, staging models imply the presence of an active disease process that, if not remediated, can lead to neuroprogression, a more malignant disease course and functional deterioration. Biological elements thought to be operative in bipolar disorder include a genetic diathesis, physical and psychic trauma, epigenetic changes, altered neurogenesis and apoptosis, mitochondrial dysfunction, inflammation, and oxidative stress. Many available agents, such as lithium, have effects on these targets. Staging models also suggest the utility of stage-specific treatment approaches that may not only target symptom reduction, but also impede illness neuroprogression. These treatment approaches range from prevention for at-risk individuals, to early intervention strategies for prodromal and newly diagnosed individuals, complex combination therapy for rapidly recurrent illness, and palliative-type approaches for those at chronic, late stages of illness. There is hope that prompt initiation of potentially disease modifying therapies may preclude or attenuate the cognitive and structural changes seen in the later stages of bipolar disorder. The aims of this paper are to: a

    Full Text Available Bipolar disorder (BPD and schizophrenia (SCH show similar neuropsychiatric behavioral disturbances, including impaired social interaction and communication, seen in autism spectrum disorder (ASD with multiple overlapping genetic and environmental influences implicated in risk and course of illness. GeneAnalytics software was used for pathway analysis and genetic profiling to characterize common susceptibility genes obtained from published lists for ASD (792 genes, BPD (290 genes and SCH (560 genes. Rank scores were derived from the number and nature of overlapping genes, gene-disease association, tissue specificity and gene functions subdivided into categories (e.g., diseases, tissues or functional pathways. Twenty-three genes were common to all three disorders and mapped to nine biological Superpathways including Circadian entrainment (10 genes, score = 37.0, Amphetamine addiction (five genes, score = 24.2, and Sudden infant death syndrome (six genes, score = 24.1. Brain tissues included the medulla oblongata (11 genes, score = 2.1, thalamus (10 genes, score = 2.0 and hypothalamus (nine genes, score = 2.0 with six common genes (BDNF, DRD2, CHRNA7, HTR2A, SLC6A3, and TPH2. Overlapping genes impacted dopamine and serotonin homeostasis and signal transduction pathways, impacting mood, behavior and physical activity level. Converging effects on pathways governing circadian rhythms support a core etiological relationship between neuropsychiatric illnesses and sleep disruption with hypoxia and central brain stem dysfunction.

O THB está relacionado com o surgimento de diversas alterações bioquímicas e moleculares em sistemas de neurotransmissão e vias de segundos-mensageiros geradores de sinais intracelulares. Essas modificações em neurônios e glia parecem estar associadas com o surgimento de sintomas maníacos e depressivos. Ainda neste contexto, disfunções na homeostasia e no metabolismo energético cerebral tem sido associado com alterações comportamentais, na modulação do humor e ritmo circadiano em humanos e em modelos animais da doença. Assim, alterações metabólicas em neurônios e células gliais têm sido associadas com quadros depressivos e maníacos. Nos últimos anos, avanços nas técnicas de neuroimagem, genéticos e de biologia moleculares têm gerado novos conhecimentos acerca das bases biológicas da bipolaridade. Os autores destacam que a doença parece estar relacionada diretamente com disfunções em diferentes mecanismos adaptativos a estresse em células neurais, gerando perda na capacidade celular de induzir neuroplasticidade e neurotrofismo, facilitando assim o surgimento da doença.In this article, the authors review relevant aspects related to the neurobiological basis of bipolar disorder. This illness has been associated with complex biochemical and molecular changes in brain circuits linked to neurotransmission and intracellular signal transduction pathways, and changes on neurons and glia have been proposed to be directly associated with clinical presentation of mania and depression. In the same context, dysfunctions on brain homeostasis and energy metabolism have been associated with alterations on circadian rythms, behavior and mood in human and animal models of bipolarity. In the recent years, advances on techniques of neuroimaging, molecular biology and genetics has provided new insights about

    Lithium, the prototypical mood stabilizer, and quetiapine, a second-generation antipsychotic, are widely used acute and maintenance pharmacotherapies for bipolar disorder. The Clinical and Health Outcomes Initiative in Comparative Effectiveness for Bipolar Disorder (Bipolar CHOICE) study was the first comparative effectiveness assessment of lithium versus quetiapine (in combination with adjunctive personalized treatment), and found no overall significant differences in efficacy and safety/tolerability outcomes between lithium and quetiapine. Completion of Bipolar CHOICE offers a timely opportunity to review the evidence regarding lithium and quetiapine for bipolar disorder. Controlled clinical trials and real-world observational studies that included quetiapine and lithium as monotherapy or as combination therapy were identified by literature search. Selected studies were reviewed in detail. Review of the available trials suggested comparable efficacy of quetiapine and lithium in acute mania, and possibly greater efficacy for quetiapine compared with lithium in acute bipolar depression and in prevention of recurrent (particularly depressive) episodes. Combination therapy including quetiapine and lithium was generally more effective than either agent alone in acute mania and bipolar maintenance, although adding lithium to quetiapine did not increase efficacy in acute bipolar depression. Safety data for quetiapine and lithium were consistent with the established profiles of the two treatments. Limitations include those of the available efficacy and effectiveness trial data. Quetiapine and lithium have overlapping but distinctive roles in different phases of bipolar disorder, and further studies of these agents (particularly in combination with one another) are warranted.

    Full Text Available Embora o transtorno bipolar (TB ocorra quase igualmente em ambos os sexos, a fenomenologia e o curso da doença diferem no homem e na mulher. No entanto, há evidências de que mulheres bipolares, mais que os homens, apresentariam início mais tardio (em especial na quinta década de vida, ciclagem rápida, mais episódios depressivos, mais mania disfórica que eufórica, estados mistos e evolução do tipo bipolar II, ainda que os achados nem sempre sejam consistentes. Embora o risco de comorbidades no TB inclua, para ambos os gêneros, abuso de álcool e drogas, homens bipolares teriam maior probabilidade de ser alcoolistas, não procurar tratamento e de se suicidar. Hipóteses sugeridas para explicar tais diferenças variam daquelas centradas em aspectos culturais ou psicológicos para as que focalizam os sistemas hormonais, como os esteróides gonadais ou o eixo tireoidiano, e até mesmo a anatomia cerebral. A influência do ciclo reprodutivo (ciclo menstrual, gravidez e menopausa sobre as opções terapêuticas no tratamento do TB é apresentada na última parte desta revisão.Although the bipolar disorder (BD occurs almost with the same frequency in both genders, the phenomenology and the outcome of the illness differ between them. Nevertheless, there is evidence that women with BD show, more than men, delayed beginning, especially in their fifth decade, more rapid cycling outcome, more depressive episodes, more dysphoric mania, more mixed states and more BD type II. Even so, the findings are not always consistent. Although the risk of comorbidities in BD includes, for both the sorts, excessive alcoholic consumption and drugs, bipolar men would have greater probability of being alcohol dependent, of not seeking treatment and of committing suicide. Suggested hypotheses to explain such differences vary from those centered in cultural or psychological aspects to those that focus on the steroids hormones, and other hormones such as cortisol

    Childhood maltreatment (abuse and neglect) can have long-term deleterious consequences, including increased risk for medical and psychiatric illnesses, such as bipolar disorder in adulthood. Emerging evidence suggests that a history of childhood maltreatment is linked to the comorbidity between medical illnesses and mood disorders. However, existing studies on bipolar disorder have not yet explored the specific influence of child neglect and have not included comparisons with individuals without mood disorders (controls). This study aimed to extend the existing literature by examining the differential influence of child abuse and child neglect on medical morbidity in a sample of bipolar cases and controls. The study included 72 participants with bipolar disorder and 354 psychiatrically healthy controls (average age of both groups was 48 years), who completed the Childhood Trauma Questionnaire, and were interviewed regarding various medical disorders. A history of any type of childhood maltreatment was significantly associated with a diagnosis of any medical illness (adjusted OR = 6.28, 95% confidence intervals 1.70-23.12, p = 0.006) and an increased number of medical illnesses (adjusted OR = 3.77, 95% confidence intervals 1.34-10.57, p = 0.012) among adults with bipolar disorder. Exposure to child abuse was more strongly associated with medical disorders than child neglect. No association between childhood maltreatment and medical morbidity was detected among controls. To summarise, individuals with bipolar disorder who reported experiencing maltreatment during childhood, especially abuse, were at increased risk of suffering from medical illnesses and warrant greater clinical attention.

    To aid the development of treatment for cognitive impairment in bipolar disorder, the International Society for Bipolar Disorders (ISBD) convened a task force to create a consensus-based guidance paper for the methodology and design of cognition trials in bipolar disorder. The task force was launched in September 2016, consisting of 18 international experts from nine countries. A series of methodological issues were identified based on literature review and expert opinion. The issues were discussed and expanded upon in an initial face-to-face meeting, telephone conference call and email exchanges. Based upon these exchanges, recommendations were achieved. Key methodological challenges are: lack of consensus on how to screen for entry into cognitive treatment trials, define cognitive impairment, track efficacy, assess functional implications, and manage mood symptoms and concomitant medication. Task force recommendations are to: (i) enrich trials with objectively measured cognitively impaired patients; (ii) generally select a broad cognitive composite score as the primary outcome and a functional measure as a key secondary outcome; and (iii) include remitted or partly remitted patients. It is strongly encouraged that trials exclude patients with current substance or alcohol use disorders, neurological disease or unstable medical illness, and keep non-study medications stable. Additional methodological considerations include neuroimaging assessments, targeting of treatments to illness stage and using a multimodal approach. This ISBD task force guidance paper provides the first consensus-based recommendations for cognition trials in bipolar disorder. Adherence to these recommendations will likely improve the sensitivity in detecting treatment efficacy in future trials and increase comparability between studies. © 2017 The Authors Bipolar Disorders Published by John Wiley & Sons Ltd.

    While there is consensus that bipolar disorder exists in children and adolescents, its diagnostic criteria are debated. Excessive sexual behavior has been reported in youth who may have juvenile bipolar disorder (JBD), and has been termed "hypersexuality." Although there is no universal definition of this term, this observation has led to a hypothesis that increased sexual behavior characterizes the bipolar syndrome in children and adolescents, and differentiates it from attention deficit hyperactivity disorder. Although this hypothesis is plausible, evidence for it is incomplete, because testing it definitively would require both establishing a standard definition of hypersexuality in children and adolescents, and also reaching consensus about the other nonsexual criteria for pediatric bipolar disorder. In addition, studies to test it would need to control factors other than JBD that are known to increase sexual behavior in children and adolescents. These include sexual abuse and related posttraumatic stress disorder, excessive exposure to sexual stimuli, psychiatric illness in general, and social variables such as family chaos and social stress. Some of these factors might increase sexual behavior in youth with bipolar disorder through psychodynamic mechanisms rather than as a result of the illness itself. Therefore, further research is needed to determine whether increased sexual behavior can serve as a diagnostically valuable criterion for bipolar disorder in children and adolescents, and whether it differentiates the disorder from other conditions known to be associated with increased sexual behavior in youth.

    The Ramadan month represents a valuable opportunity to test the hypothesis that the course of the illness of bipolar patients can be disrupted by the change in social rhythm which usually occurs during this month. The objectives of this study were to follow up the mood state and blood lithium level of fasting Muslim bipolar patients who had been on lithium therapy for at least 3 months, and were clinically stable before being included in the study. Twenty bipolar patients were enrolled during the month of Ramadan in 1997. Diagnosis of bipolar disorder was according to ICD-10 criteria. Patients were assessed during the week before Ramadan, the second and the fourth weeks of the fasting month and the first week after its end, with the Hamilton Depression and Bech-Rafaelsen scales. The plasma concentration of lithium was also assessed. The main finding of the study was that 45% of the patients relapsed, 70% during the second week and the remaining patients at the end of Ramadan. These relapses were not related to plasma concentration of lithium. Most of the relapses were manic (71.4 %). Patients who did not relapse had insomnia and anxiety during the second and third weeks of the study. Side-effects of lithium increased and were observed in 48% of the sample, mostly dryness of the mouth with thirst and tremor. The result of this pilot study indicates that the Ramadan month may disrupt the mood state of bipolar patients. More studies are needed to confirm this observation and to evaluate the validity of the Ramadan model to study the impact of social rhythms on bipolar patients.

    Full Text Available Introduction: Bipolar disorder is a psychiatric condition that is also called manic-depressive disease. It causes unusual changes in mood, energy, activity levels, and the ability to carry out day-to-day tasks. In the present study, 3 sets of data were considered and analyzed: first, all papers categorized under Bipolar Disorders in Science Citation Index Expanded (SCI-E database through 2001-2011; second, papers published by the international journal of Bipolar Disorders indexed in SCI-E during a period of 11 years; and third, all papers distributed by the international journal of Bipolar Disorders indexed in MEDLINE during the period of study. Methods: The SCI-E database was used to extract all papers indexed with the topic of Bipolar Disorders as well as all papers published by The International Journal of Bipolar Disorders. Extraction of data from MEDLINE was restricted to the journals name from setting menu. The Science of Science Tool was used to map the co-authorship network of papers published by The International Journal of Bipolar Disorders through 2009-2011. Results: Analysis of data showed that the majority of publications in the subject area of bipolar disorders indexed in SCI-E were published by The International Journal of Bipolar Disorders. Although journal articles consisted of 59% of the total publication type in SCI-E, 65% of publications distributed by The Journal of Bipolar Disorders were in the form of meetingabstracts. Journal articles consisted of only 23% of the total publications. USA was the leading country regarding sharing data in the field of bipolar disorders followed by England, Canada, and Germany. Conclusion: The editorial policy of The International Journal of Bipolar Disorders has been focused on new themes and new ways of researching in the subject area of bipolar disorder. Regarding the selection of papers for indexing, the SCI-E database selects data more comprehensively than MEDLINE. The number of papers

    Full Text Available Childhood and adolescent bipolar disorder diagnosis has been increasing recently. Since studies evaluating attempted suicide rates in children and adolescents have shown bipolarity to be a significant risk factor, diagnosis and treatment of bipolarity has become a very important issue. Since there is a lack of specific diagnostic criteria for especially preadolescent samples and evaluations are made mostly symptomatically, suspicions about false true diagnosis and increased prevalence rates have emerged. This situation leads to controversial data about the prevalence rates of bipolar disorder in children and adolescents. The aim of this article is to review the prevalence of childhood and adolescent bipolar disorder in community, inpatient and outpatient based samples in literature.

    Full Text Available Bipolar disorder is a chronic disorder in which irregular course of depressive, mania or mixed episodes or a complete recovery between episodes can be observed. The studies about the effects of traumatic events on bipolar disorder showed that they had significant and long-term effects on the symptoms of the disorder. Psychosocial stress might change the neurobiology of bipolar disorder over time. The studies revealed that the traumatic events could influence not only the onset of the disorder but also the course of the disorder and in these patients the rate of suicide attempt and comorbid substance abuse might increase. Bipolar patients who had childhood trauma had an earlier onset, higher number of episodes and comorbid disorders. In this review, the relationship between childhood trauma and bipolar disorder is reviewed. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2015; 7(2: 157-165

    Carlson, Gabrielle A; Meyer, Stephanie E

    2006-01-01

    This review addresses the phenomenology of mania/bipolar disorder from a developmental psychopathology perspective and uses cases with longitudinal information to illustrate major points. Beginning with a summary of the phenomenology of bipolar illness as it occurs in adults, the authors identify diagnostic complexities unique to children and adolescents. These include the challenges of characterizing elation and grandiosity; differentiating mania from comorbid symptoms, rages, sequelae of maltreatment, and typical developmental phenomena; and the unique manifestations of psychosis. We conclude with the observation that a significant difference between early and later onset bipolar disorder is that, in the former, there appears to be a global delay or arrest in the development of appropriate affect regulation; whereas in adult-onset bipolar illness, emotion dysregulation generally presents as an intermittent phenomenon. At this juncture, the study of childhood bipolar illness would benefit from a developmental psychopathology perspective to move beyond the level of cross-sectional symptom description to begin to study individuals over time, focusing on developmental, environmental, genetic, and neurobiological influences on manifest behavior.

    Full Text Available Berit Kerner Semel Institute for Neuroscience and Human Behavior, University of California, Los Angeles, Los Angeles, CA, USA Abstract: Bipolar disorder is a common, complex genetic disorder, but the mode of transmission remains to be discovered. Many researchers assume that common genomic variants carry some risk for manifesting the disease. The research community has celebrated the first genome-wide significant associations between common single nucleotide polymorphisms (SNPs and bipolar disorder. Currently, attempts are under way to translate these findings into clinical practice, genetic counseling, and predictive testing. However, some experts remain cautious. After all, common variants explain only a very small percentage of the genetic risk, and functional consequences of the discovered SNPs are inconclusive. Furthermore, the associated SNPs are not disease specific, and the majority of individuals with a “risk” allele are healthy. On the other hand, population-based genome-wide studies in psychiatric disorders have rediscovered rare structural variants and mutations in genes, which were previously known to cause genetic syndromes and monogenic Mendelian disorders. In many Mendelian syndromes, psychiatric symptoms are prevalent. Although these conditions do not fit the classic description of any specific psychiatric disorder, they often show nonspecific psychiatric symptoms that cross diagnostic boundaries, including intellectual disability, behavioral abnormalities, mood disorders, anxiety disorders, attention deficit, impulse control deficit, and psychosis. Although testing for chromosomal disorders and monogenic Mendelian disorders is well established, testing for common variants is still controversial. The standard concept of genetic testing includes at least three broad criteria that need to be fulfilled before new genetic tests should be introduced: analytical validity, clinical validity, and clinical utility. These criteria are

    Bipolar disorder is a chronic pathology whose management must lead to limit the social, professional and family impacts as well as suicidal risk. The treatment of acute episodes and prophylaxis is based on mood stabilizer treatments whose lithium is a leader. They will be chosen according to the background and history of the disease. Anti-depressants must be used with care to minimize the risk of manic episode and the induction of rapid cycles. The prognosis is not solving major episodes but avoiding major mood episodes. The management of residual symptoms (especially neuro-cognitive) is also a major challenge prognosis and justifies the implementation of adjuvant psychotherapeutic strategies.

    Frequently used in a pejorative sense, "disease mongering" connotes a widening of the diagnostic boundaries of illness. Pharmaceutical companies conduct disease awareness campaigns on the pretext of educating the public about the prevention of illness or the promotion of health. Encouraged by disease awareness advertisements, people gradually become filled with concern that they are ill and need medical treatment. As a result, pharmacotherapy is increasingly being applied to ever-milder conditions, leading to potentially unnecessary medication, wasted resources, and even adverse side effects. Among all fields of clinical medicine, psychiatry is undoubtedly the most vulnerable to the danger of disease mongering. In Japan, depression provides the most drastic example of the impact of disease awareness campaigns on the number of patients seeking treatment. Until the late 1990s, Japanese psychiatrists focused almost exclusively on psychosis and endogenous depression, the latter being severe enough to require conventional forms of antidepressants, known as tricyclic antidepressants, and even hospitalization. At this time, people's attitude toward depression was generally unfavorable. Indeed, the Japanese word for clinical depression, utubyo, has a negative connotation, implying severe mental illness. This situation, however, changed immediately after fluvoxiamine (Luvox-Fujisawa, Depromel-Meiji Seika), the first selective serotonin re-uptake inhibitor (SSRI) to receive approval in Japan, was introduced in 1999. In order to aid the drug's acceptance by the Japanese public, pharmaceutical companies began using the catchphrase kokoro no kaze, which literally means "a cold of the soul". Thus armed with this phrase, the pharmaceutical industry embarked on a campaign to lessen the stigma surrounding depression. According to national data from the Ministry of Health and Welfare, the number of patients with a diagnosis of mood disorder increased from 327,000 in 1999 to 591

    2017-02-01

    Bipolar disorder is a severe, lifelong mood disorder for which little is currently understood of the genetic mechanisms underlying risk. By examining related dimensional phenotypes, we may further our understanding of the disorder. Creativity has a historical connection with the bipolar spectrum and is particularly enhanced among unaffected first-degree relatives and those with bipolar spectrum traits. This suggests that some aspects of the bipolar spectrum may confer advantages, while more severe expressions of symptoms negatively influence creative accomplishment. Creativity is a complex, multidimensional construct with both cognitive and affective components, many of which appear to reflect a shared genetic vulnerability with bipolar disorder. It is suggested that a subset of bipolar risk variants confer advantages as positive traits according to an inverted-U-shaped curve with clinically unaffected allele carriers benefitting from the positive traits and serving to maintain the risk alleles in the population. The association of risk genes with creativity in healthy individuals (e.g., NRG1), as well as an overall sharing of common genetic variation between bipolar patients and creative individuals, provides support for this model. Current findings are summarized from a multidisciplinary perspective to demonstrate the feasibility of research in this area to reveal the mechanisms underlying illness.

    Rapid-cycling bipolar disorder represents a frequent severe subtype of illness which has been associated with poor response to pharmacological treatment. Aim of the present article is to provide an updated review of biological markers associated with rapid-cycling bipolar disorder. A research in the main database sources has been conducted to identify relevant papers about the topic. Rapid-cycling bipolar disorder patients seem to have a more frequent family history for bipolar spectrum disorders (d range: 0.44-0.74) as well as an increased susceptibility to DNA damage or mRNA hypo-transcription (d range: 0.78-1.67) than non rapid-cycling ones. A susceptibility to hypothyroidism, which is exacerbated by treatment with lithium, is possible in rapid-cycling bipolar disorder, but further studies are needed to draw definitive conclusions. Rapid-cycling bipolar patients might have more insuline resistance as well as more severe brain changes in frontal areas (d range: 0.82-0.94) than non rapid-cycling ones. Many questions are still open about this topic. The first is whether the rapid-cycling is inheritable or is more generally the manifestation of a severe form of bipolar disorder. The second is whether some endocrine dysfunctions (diabetes and hypothyroidism) predispose to rapid-cycling or rapid-cycling is the consequence of drug treatment or medical comorbidities (e.g. obesity).

Depressive episodes in both bipolar I and II disorder are more numerous and last for longer duration than either manic or hypomanic episodes. In addition depressive episodes are associated with higher morbidity and mortality. While multiple agents, including all 5 atypical antipsychotics, have demonstrated efficacy and earned US FDA indication for manic phase of bipolar illness, the acute treatment of bipolar depression is less well-studied. The first treatment approved by the US FDA for acute bipolar depression was the combination of the atypical antipsychotic olanzapine and the antidepressant fluoxetine. Recently, quetiapine monotherapy has demonstrated efficacy in the treatment of depressive episodes associated with both bipolar I and II disorder and has earned US FDA indication for the same.Keywords: bipolar disorder, quetiapine, BOLDER studies

    A bipolar pulse forming transmission line module for linear induction accelerators having first, second, third, fourth, and fifth planar conductors which form an interleaved stack with dielectric layers between the conductors. Each conductor has a first end, and a second end adjacent an acceleration axis. The first and second planar conductors are connected to each other at the second ends, the fourth and fifth planar conductors are connected to each other at the second ends, and the first and fifth planar conductors are connected to each other at the first ends via a shorting plate adjacent the first ends. The third planar conductor is electrically connectable to a high voltage source, and an internal switch functions to short a high voltage from the first end of the third planar conductor to the first end of the fourth planar conductor to produce a bipolar pulse at the acceleration axis with a zero net time integral. Improved access to the switch is enabled by an aperture through the shorting plate and the proximity of the aperture to the switch.

    Many bipolar disorder patients exhibit mixed affective states, which portend a generally more severe illness course and treatment resistance. In the previous renditions of Diagnostic and Statistical Manual mixed states were narrowly defined in the context of bipolar I disorder, but with the advent of DSM-5 the term "mixed episode" was dropped and replaced by "mixed features" specifier which could be broadly applied to manic, hypomanic and depressive episodes in both the bipolar spectrum and major depressive disorders. This paradigm shift reflected their significance in the prognosis and overall management of mood disorders, so that the clinicians should thoroughly familiarize themselves with the contemporary notions surrounding these conditions. The purpose of this manuscript is to bring to light the current conceptualizations regarding the etiology, pathogenesis and treatment of mixed states. To achieve this goal, in June 2016 an extensive literature search was undertaken using the PubMed database. Some exploratory terms utilized included "mixed states", "mixed episodes", "switching", "rapid cycling" cross referenced with "bipolar disorder". Focusing on the most relevant and up to date studies, it was revealed that mixed states result from genetic susceptibility in the circadian and dopamine neurotransmission apparatuses and disturbance in the intricate catecholamine-acetylcholine neurotransmission balance which leads to mood fluctuations. The management of mixed states is challenging with atypical antipsychotics, newer anticonvulsants and electroconvulsive therapy emerging as the foremost treatment options. In conclusion, while progress has been made in the neurobiological understanding of mixed states, the currently available therapeutic modalities have only shown limited effectiveness.

  3. The Reciprocal Relationship between Bipolar Disorder and Social Interaction: A Qualitative Investigation.

    Evidence suggests that social support can influence relapse rates, functioning and various clinical outcomes in people with bipolar disorder. Yet 'social support' is a poorly defined construct, and the mechanisms by which it affects illness course in bipolar disorder remain largely unknown. Key aims of this study were to ascertain which facets of social interaction affect mood management in bipolar disorder, and how symptoms of bipolar disorder can influence the level of support received. Semi-structured qualitative interviews were conducted with 20 individuals with bipolar disorder. Questions were designed to elicit: the effects of social interaction upon the management and course of bipolar disorder; and the impact of bipolar disorder upon social relationships. An inductive thematic analysis was used to analyse the data. Empathy and understanding from another person can make it easier to cope with bipolar disorder. Social interaction can also provide opportunities to challenge negative ruminative thoughts and prevent the onset of a major mood episode. The loss of social support, particularly through bereavement, creates a loss of control and can trigger mania or depression. Hypomanic symptoms can facilitate new social connections, whereas disinhibited and risky behaviour exhibited during mania can cause the breakdown of vital relationships. An in-depth clinical formulation of an individual's perceptions of how their illness affects and is affected by social interaction is crucial to understanding psychosocial factors which influence mood management.

    Bipolar disorder is a serious illness in children that adversely affects social, academic, emotional, and family functioning. Its prevalence in adolescents is estimated to be as high as 1%. The diagnosis of bipolar disorder in young children is often a challenge, largely because the symptoms may differ from those exhibited in late adolescence and adulthood. The occurrence of comorbid disorders such as attention-deficit/hyperactivity disorder also may complicate the diagnosis. Despite the significant severity and chronicity of this disorder in youths, very few controlled data are available to guide treatment decisions in children and adolescents. The treatment literature consists largely of open studies, case series, and case reports. Therefore, a pressing need exists for controlled trials to determine whether medications commonly used to treat the disorder in children are significantly superior to placebo, as well as to determine whether initial monotherapy or combination treatment is warranted. This article will review the epidemiology, diagnosis, course of illness, and treatment of bipolar disorder in children and adolescents.

    To date, cognitive impairment has been thought to be an integral part of bipolar disorder. In clinical staging models, cognitive impairment is one of the hallmarks to define the clinical stage and it plays an important role in identifying the risk factors for progression to later stages of the illness. It is important to examine neurocognitive performance over longer periods to test the hypothesis of neuroprogression of bipolar disorder. A comprehensive neuropsychological test battery was applied at baseline and five years later to 56 euthymic older outpatients with bipolar disorder (mean age = 68.35 years, range: 60-90 years) and to a demographically matched sample of 44 healthy subjects. A group-by-time repeated measures multivariate analysis of variance was performed to measure changes over time for the two groups. The impact of baseline illness characteristics on the intra-individual change in neurocognitive performance within the bipolar disorder group was studied by using logistic regression analysis. At baseline and at follow-up, patients with bipolar disorder performed worse on all neurocognitive measures compared to the matched healthy subjects. However, there was no significant group-by-time interaction between the patients with bipolar disorder and the comparison group. Although older patients with bipolar disorder had worse cognitive function than healthy subjects, they did not have greater cognitive decline over a five-year period. The change in acquired cognitive impairment of patients with bipolar disorder might parallel the cognitive development as seen in normal aging. © 2016 John Wiley & Sons A/S.

    Bipolar disorder is characterized by a hypersensitivity to reward-relevant cues and a propensity to experience an excessive increase in approach-related affect, which may be reflected in hypo/manic symptoms. The present study examined the relationship between relative left-frontal electroencephalographic (EEG) activity, a proposed neurophysiological index of approach-system sensitivity and approach/reward-related affect, and bipolar course and state-related variables. Fifty-eight individuals with cyclothymia or bipolar II disorder and 59 healthy control participants with no affective psychopathology completed resting EEG recordings. Alpha power was obtained and asymmetry indices computed for homologous electrodes. Bipolar spectrum participants were classified as being in a major/minor depressive episode, a hypomanic episode, or a euthymic/remitted state at EEG recording. Participants were then followed prospectively for an average 4.7 year follow-up period with diagnostic interview assessments every four-months. Sixteen bipolar spectrum participants converted to bipolar I disorder during follow-up. Consistent with hypotheses, elevated relative left-frontal EEG activity at baseline 1) prospectively predicted a greater likelihood of converting from cyclothymia or bipolar II disorder to bipolar I disorder over the 4.7 year follow-up period, 2) was associated with an earlier age-of-onset of first bipolar spectrum episode, and 3) was significantly elevated in bipolar spectrum individuals in a hypomanic episode at EEG recording. This is the first study to identify a neurophysiological marker that prospectively predicts conversion to bipolar I disorder. The fact that unipolar depression is characterized by decreased relative left-frontal EEG activity suggests that unipolar depression and vulnerability to hypo/mania may be characterized by different profiles of frontal EEG asymmetry.

    Many people experience irritability when manic, hypomanic, or depressed, yet its impact on illness severity and quality of life in bipolar and schizoaffective disorders is poorly understood. This study aimed to examine the relationship between irritability and symptom burden, functioning, quality of life, social support, suicidality, and overall illness severity in a naturalistic cohort of people with bipolar I or schizoaffective disorder. We used data from 239 adult outpatients with bipolar I or schizoaffective disorder in the Bipolar Comprehensive Outcomes Study (BCOS) - a non-interventional observational study with a 2-year follow-up period. Baseline demographic and clinical characteristics of participants with and without irritability were compared. A mixed-model repeated measures analysis was conducted to examine the longitudinal effect of irritability on clinical and quality-of-life variables over follow-up using significant baseline variables. At baseline, 54% of participants were irritable. Baseline irritability was associated with illness severity, mania, depression, psychotic symptoms, suicidality, poor functioning, and quality of life, but not diagnosis (schizoaffective/bipolar disorder). Participants with irritability were less likely to have a partner and perceived less adequate social support. On average, over follow-up, those with irritability reported more symptoms, functional impairment, and suicidality. Furthermore, the effects of irritability could not be fully explained by illness severity. Irritability was associated with more negative symptomatic, functional, and quality-of-life outcomes and suicidality. The identification, monitoring, and targeted treatment of irritability may be worth considering, to enhance health and wellbeing outcomes for adults with bipolar and schizoaffective disorders. © 2017 John Wiley & Sons A/S.

Asenapine is a tetracyclic drug with antidopaminergic and antiserotonergic activity with a unique sublingual route of administration. In this review, we examine and summarize the available literature on the safety, efficacy, and tolerability of asenapine in the treatment of bipolar disorder (BD. Data from randomized, double-blind trials comparing asenapine to placebo or olanzapine in the treatment of acute manic or mixed episodes showed asenapine to be an effective monotherapy treatment in clinical settings; asenapine outperformed placebo and showed noninferior performance to olanzapine based on improvement in the Young Mania Rating Scale scores. There are limited data available on the use of asenapine in the treatment of depressive symptoms of BD, or in the maintenance phase of BD. The available data are inconclusive, suggesting the need for more robust data from prospective trials in these clinical domains. The most commonly reported adverse effect associated with use of asenapine is somnolence. However, the somnolence associated with asenapine use did not cause significant rates of discontinuation. While asenapine was associated with weight gain when compared to placebo, it appeared to be modest when compared to other atypical antipsychotics, and its propensity to cause increases in hemoglobin A1c or serum lipid levels appeared to be

Currently, ziprasidone is approved by the US Food and Drug Administration for the acute treatment of psychosis in schizophrenia and mania in bipolar disorder. When compared to certain other atypical antipsychotics, ziprasidone appears to have a relatively benign side effect profile, especially as regards metabolic effects eg, weight gain, serum lipid elevations and glucose dysregulation. Taken together, these data suggest that ziprasidone may be a first line treatment for patients with bipolar mania. However, ziprasidone is a relatively new medication for which adverse events after long-term use and/or in vulnerable patient populations must be studied. Unstudied areas of particular importance include the efficacy and safety of ziprasidone in the treatment of bipolar depression and relapse prevention of mania as, well as in the subpopulations of pregnant women, the elderly and pediatric patients. The emergence of mania in patients taking ziprasidone is another topic for further study.Keywords: antipsychotic, bipolar disorder, mania, mood disorder, neuroleptic, ziprasidone

This survey study assessed experiences and identified clinical insights of individuals with bipolar disorder. An Internet-based monitor system database was screened for patients with bipolar disorder in Japan (February and March 2013. Of 1,050 patients, 457 completed surveys, and results were analyzed with descriptive statistics. Approximately one-fourth of respondents were diagnosed with bipolar disorder on their first visit to medical institutions, although the most common initial diagnosis was depression/depressive state (65%. Mean time lag between first-time visit to a medical institution and receipt of correct diagnosis of bipolar disorder was 4 years; one-third of patients experienced more than 5 years of lag time. Three perceived reasons for lapsed time before correct diagnosis were “(patients Did not consider manic symptoms as illness, and did not tell the doctor about them,” “I (patient did not know of bipolar disorder,” and “Lack of communication between my doctor and myself (patient.” Among participants who believed that they were initially incorrectly diagnosed and improperly treated, most experienced socioeconomic problems, such as having long-term inability to work or to study (65%. Sources of encouragement for participants included “To have someone to consult with” (41% followed by having “People around me treat me the same as before” (40%. Individuals with bipolar disorder reported a time lag of many years before accurate diagnosis, and substantial burden imposed by the illness.

    Bipolar disorder is a severe affective disorder which can present in adolescence, or sometimes earlier, and often requires a pharmacotherapeutic approach. The phenomenology of bipolar disorder in children and adolescents appears to differ from that of adult patients, prompting the need for specific pharmacotherapy guidelines for long-term management in this patient population. Current treatment guidelines were mainly developed based on evidence from studies in adult patients, highlighting the requirement for further research into the pharmacotherapy of children and adolescents with bipolar disorder. This review compares and critically analyzes the available guidelines, discussing the recommended medication classes, their mechanisms of action, side effect profiles and evidence base.

    A bipolar permanent magnetic guideway (PMG) has a unique magnetic field distribution profile which may introduce a better levitation performance and stability to the high- superconducting (HTS) maglev system. The dynamic vibration properties of multiple YBCO bulks arranged into different arrays positioned above a bipolar PMG and free to levitate were investigated. The acceleration and resonance frequencies were experimentally measured, and the stiffness and damping coefficients were evaluated for dynamic stability. Results indicate that the levitation stiffness is closely related to the field-cooling-height and sample positioning. The damping ratio was found to be low and nonlinear for the Halbach bipolar HTS-PMG system.

    Full Text Available Abstract Background Bipolar disorder is recognized as a major mental health issue, and its economic impact has been examined in the United States. However, there exists a general scarcity of published studies and lack of standardized data on the burden of the illness across European countries. In this systematic literature review, we highlight the epidemiological, clinical, and economic outcomes of bipolar disorder in Europe. Methods A systematic review of publications from the last 10 years relating to the burden of bipolar disorder was conducted, including studies on epidemiology, patient-related issues, and costs. Results Data from the UK, Germany, and Italy indicated a prevalence of bipolar disorder of ~1%, and a misdiagnosis rate of 70% from Spain. In one study, up to 75% of patients had at least one DSM-IV comorbidity, commonly anxiety disorders and substance/alcohol abuse. Attempted suicide rates varied between 21%–54%. In the UK, the estimated rate of premature mortality of patients with bipolar I disorder was 18%. The chronicity of bipolar disorder exerted a profound and debilitating effect on the patient. In Germany, 70% of patients were underemployed, and 72% received disability payments. In Italy, 63%–67% of patients were unemployed. In the UK, the annual costs of unemployment and suicide were £1510 million and £179 million, respectively, at 1999/2000 prices. The estimated UK national cost of bipolar disorder was £4.59 billion, with hospitalization during acute episodes representing the largest component. Conclusion Bipolar disorder is a major and underestimated health problem in Europe. A number of issues impact on the economic burden of the disease, such as comorbidities, suicide, early death, unemployment or underemployment. Direct costs of bipolar disorder are mainly associated with hospitalization during acute episodes. Indirect costs are a major contributor to the overall economic burden but are not always recognized in

    The formation of extreme localization structures in nonlinear dispersive media (water or optical fibres) can be explained and described by the focusing nonlinear Schrödinger equation (NLSE). The NLSE is especially important in understanding how solitons on a condensate background (SCB) appear from a small perturbation through modulation instability. We have studied theoretically SCB solutions solved with the dressing method. A class of bipolar-rogue-wave structures that are constructed by collisions between elementary SCB or bipolar solitonic solutions was found. Besides, we have also found a new class of regular bright solitonic rogue waves that are originated from the collision between two bipolar-rogue-wave structures. The bipolar-rogue-wave structures can be considered to provide a new prototype for rogue-waves dynamics modeling. Our results extend previous studies in the area of rogue waves and may be important in the study of oceanography and optics.

    Full Text Available Background: Bipolar disorder is a relatively common, long-term, and disabling psychiatric illness that is associated with high levels of functional impairment, morbidity, mortality, and an increased risk of suicide. Psychiatric co-morbidity in bipolar disorder ranges from 57.3% to 74.3%, whereas medical co-morbidity varies from 2.7-70%. Indian scenario in this aspect is not clear. Materials and Methods: The objective was to ascertain the prevalence of physical and psychiatric co-morbidities in patients attending a tertiary care center over a period of 1 year and its relationship with socio-demographic and clinical variables. One hundred and twenty-five case record files were included in the review. OPCRIT software was used for re-establishing the diagnosis of bipolar disorder, which yielded 120 cases. A semi-structured pro-forma, specifically designed for the study, was used to collect the socio-demographic and clinical details. Results: Co-morbid psychiatric disorders were found in 52 (43.3% of the sample, whereas co-morbid physical illness was present in 77 (64.2% patients. The most common psychiatric disorder associated was substance use disorder (27.5%, whereas co-morbid cardiovascular disorder was the most frequent physical diagnosis in the sample (20%. Discussion: The prevalence of co-morbid psychiatric disorders in bipolar patients was lower than that reported in western literature. It could be related to retrospective nature of study or reflect true lower prevalence rates. Also, certain disorders such as eating disorders were absent in our sample, and migraine diagnosis was very infrequent.

  10. Valuing happiness is associated with bipolar disorder.

    Although people who experience happiness tend to have better psychological health, people who value happiness to an extreme tend to have worse psychological health, including more depression. We propose that the extreme valuing of happiness may be a general risk factor for mood disturbances, both depressive and manic. To test this hypothesis, we examined the relationship between the extreme valuing of happiness and risk for, diagnosis of, and illness course for bipolar disorder (BD). Supporting our hypothesis, the extreme valuing of happiness was associated with a measure of increased risk for developing BD (Studies 1 and 2), increased likelihood of past diagnosis of BD (Studies 2 and 3), and worse prospective illness course in BD (Study 3), even when controlling for current mood symptoms (Studies 1-3). These findings indicate that the extreme valuing of happiness is associated with and even predicts BD. Taken together with previous evidence, these findings suggest that the extreme valuing of happiness is a general risk factor for mood disturbances. More broadly, what emotions people strive to feel may play a critical role in psychological health. (c) 2015 APA, all rights reserved).

    Suicide is a major public health problem worldwide. It contributes for more than one million deaths each year. Since previous suicidal attempt was considered as the best predictor of future suicide, identifying factors behind suicidal attempt are helpful to design suicide prevention strategies. The aim of this study was to assess socio-demographic characteristics, clinical profile and prevalence of existing mental illness among patients presenting with suicidal attempt to emergency services of general hospitals in South Ethiopia. We conducted a cross-sectional study on patients presenting with complications of suicidal attempt to emergency departments of two general hospitals in Hawassa city from November, 2014 to August, 2015. Data was collected using semi-structured questionnaire which contained socio-demographic and clinical variables. The Mini International Neuropsychiatric Interview version 5 (MINI PLUs) was used to assess the prevalence of existing mental illness among study participants. Data was entered and analyzed using IBM SPSS statistics 21 software package. A total of 96 individuals were assessed, of whom 56 (58.3%) were females. The mean age of study participants was 21.5 (8.0) years. The majority, 75 (78.1%), of the study participants were aged below 25 years. Ingesting pesticide poisons and corrosive agent were used by the majority to attempt suicide. Mental illness was found in only three (3.1%) of the study participants. Impulsivity (the time between decision to attempt suicide and the actual attempt of less than 5 min) was reported by 30 (31.2%) of the study participants, of whom 18 (60%) were males. Males were found three times more likely to attempt suicide impulsively than women (COR = 3.0, 95% CI 1.2-7.3). Quarreling with family members, facing financial crisis, and having unplanned and unwanted pregnancy were reported by the majority of study participants as immediate reasons to attempt suicide. The presence of stressful life events and

    About one-third of lithium-treated, bipolar patients are excellent lithium responders; that is, lithium monotherapy totally prevents further episodes of bipolar disorder for ten years and more. These patients are clinically characterized by an episodic clinical course with complete remission, a bipolar family history, low psychiatric comorbidity, mania-depression episode sequences, a moderate number of episodes, and a low number of hospitalizations in the pre-lithium period. Recently, it has been found that temperamental features of hypomania (a hyperthymic temperament) and a lack of cognitive disorganization predict the best results of lithium prophylaxis. Lithium exerts a neuroprotective effect, in which increased expression of brain-derived neurotrophic factor (BDNF) and inhibition of the glycogen synthase kinase-3 (GSK-3) play an important role. The response to lithium has been connected with the genotype of the BDNF gene and serum BDNF levels. A better response to lithium is connected with the Met allele of the BDNF Val/Met polymorphism, as is a hyperthymic temperament. Excellent lithium responders have normal cognitive functions and serum BDNF levels, even after long-term duration of the illness. The preservation of cognitive functions in long-term lithium-treated patients may be connected with the stimulation of the BDNF system, with the resulting prevention of affective episodes exerting deleterious cognitive effects, and possibly also with lithium's antiviral effects. A number of candidate genes that are related to neurotransmitters, intracellular signaling, neuroprotection, circadian rhythms, and other pathogenic mechanisms of bipolar disorder were found to be associated with the lithium prophylactic response. The Consortium on Lithium Genetics (ConLiGen) has recently performed the first genome-wide association study on the lithium response in bipolar disorder.

    Bipolar disorder is a common chronic illness characterized by high levels of morbidity and all-cause mortality. Lithium is one of the gold standard mood stabilizer treatments, but the identification of good, partial and non-responders in clinical settings is inconsistent. We used an established rating scale (the Alda scale) to classify the degree of lithium response (good response, partial response, non-response) in a large, multicentre clinically representative sample of well-characterized cases of bipolar disorders I and II. Next, we examined previously reported clinical predictors of response to determine which factors significantly differentiated between the three response groups. Of 754 cases, 300 received lithium, for at least 6 months, as a treatment for bipolar disorder (40%). Of these cases, 17% were classified as good response, 52% as partial response and 31% as non-response. Lifetime history of mixed episodes ( p = 0.017) and alcohol use disorders ( p = 0.015) both occurred in >20% of partial response and non-response groups but bipolar disorder I was of borderline statistical significance, being more frequent in the good response group (38%) compared with the non-response group (18%). There was a trend ( p = 0.06) for bipolar disorder II to be associated with non-response. Only three factors previously identified as predictors of lithium response significantly differentiated the response groups identified in our sample. Interestingly, these factors have all been found to co-occur more often than expected by chance, and it can be hypothesized that they may represent a shared underlying factor or dimension. Further prospective studies of predictors and the performance of the Alda scale are recommended.

    Bipolar disorder (BD) is a chronic, frequently comorbid condition characterized by high rates of mood episode recurrence and suicidality. Little is known about prospective longitudinal characterization of BD type II (BD II) versus type I (BD I) in relation to time to depressive recurrence and recovery from major depressive episode. We therefore assessed times to depressive recurrence/recovery in tertiary clinic-referred BD II versus I patients. Outpatients referred to Stanford BD Clinic during 2000-2011 were assessed with Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation and with Clinical Monitoring Form during up to 2 years of naturalistic treatment. Prevalence and clinical correlates of bipolar subtype in recovered (euthymic ≥8 weeks) and depressed patients were assessed. Kaplan-Meier analyses assessed the relationships between bipolar subtype and longitudinal depressive severity, and Cox proportional hazard analyses assessed the potential mediators. BD II versus BD I was less common among 105 recovered (39.0 vs. 61.0%, p = 0.03) and more common among 153 depressed (61.4 vs. 38.6%, p = 0.006) patients. Among recovered patients, BD II was associated with 6/25 (24.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics and hastened depressive recurrence (p = 0.015). Among depressed patients, BD II was associated with 8/25 (33.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics, but only non-significantly associated with delayed depressive recovery. BD II versus BD I was significantly associated with current depression and hastened depressive recurrence, but only non-significantly associated with delayed depressive recovery. Research on bipolar subtype relationships with depressive recurrence/recovery is warranted to enhance clinical management of BD patients.

    Full Text Available Young Sup Woo, Hee Ryung Wang, Won-Myong Bahk Department of Psychiatry, Yeouido St Mary's Hospital, The Catholic University of Korea, Seoul, Korea Abstract: Lurasidone is a benzisothiazol derivative and an atypical antipsychotic approved by the US Food and Drug Administration for the acute treatment of adults with schizophrenia (October 2010 and bipolar 1 depression (June 2013. Lurasidone has a strong antagonistic property at the D2, serotonin (5-HT2A, and 5-HT7 receptors, and partial agonistic property at the 5-HT1A receptor. Lurasidone also has lower binding affinity for the α2C and 5-HT2C receptor. Lurasidone is rapidly absorbed (time to maximum plasma concentration: 1–3 hours, metabolized mainly by CYP3A4 and eliminated by hepatic metabolism. In two large, well-designed, 6-week trials in adult patients with bipolar 1 depression, lurasidone monotherapy and adjunctive therapy with mood stabilizers were significantly more effective than placebo at improving depressive symptoms assessed using the Montgomery–Åsberg Depression Rating Scale total score. In both trials, lurasidone also reduced the Clinical Global Impression–Bipolar Severity depression score to a greater extent than placebo. In these two trials, discontinuation rates due to adverse events in the lurasidone group were small (<7% and were not different from those of the placebo group. The most common adverse events in the lurasidone group were headache, nausea, somnolence, and akathisia. The changes in lipid profiles, weight, and parameters of glycemic control were minimal, and these findings were in line with those observed in schizophrenia trials. Further active comparator trials and long-term tolerability and safety data in bipolar patients are required. Lurasidone may be an option for the management of depressive symptoms in patients with bipolar 1 disorder, and it may be considered as a treatment alternative for patients who are at high risk for metabolic abnormalities

  16. Valproate use in children and adolescents with bipolar disorder.

    This review aims to provide an update on valproate use in children and adolescents with bipolar disorder by summarising currently available clinical trials results. Guidelines for the treatment of type I bipolar disorder in children and adolescents, with or without psychotic features, recommend valproate, alone or in combination with an atypical antipsychotic, as a first-line treatment option; however, most randomised and open-label studies investigating valproate in paediatric populations have only evaluated a small number of participants. Therefore, the data from these studies need to be interpreted cautiously. A further complicating issue is the controversy surrounding the definition and diagnosis of bipolar disorders in this age group. Data suggest that valproate may be particularly useful for patients whose symptoms have not been responsive to lithium, or as part of combination therapy. Evidence from randomised controlled trials show that valproate monotherapy is associated with a Young Mania Rating Scale (YMRS) response rate (percentage of patients with a reduction in YMRS score from baseline to endpoint of >/=50%) of 53%, while combination therapy with valproate plus quetiapine is associated with a YMRS response rate of 87%; however, placebo response rates were high, emphasising the need for caution when interpreting data from open-label trials. At present, data supporting the efficacy and safety of mood stabilisers for the treatment of bipolar disorders in children and adolescents are limited; therefore, well designed, randomised controlled clinical studies are needed to identify and confirm the potential roles of valproate in children and adolescents with bipolar disorders, particularly in those with psychiatric co-morbidities. Furthermore, clinical studies are required to clarify the efficacy and tolerability profile of valproate in comparison with other agents used in paediatric and adolescent bipolar disorder.

    Given the paucity of information available regarding standardized ratings of depression symptoms in bipolar manic states, and in particular those in older adults, we explored depression ratings in symptomatic participants in a multicenter study of treatment of bipolar I disorder in late life. Baseline data was obtained from the first 100 patients enrolled in an NIMH-funded, 9-week, randomized, double-blind RCT comparing treatment with lithium or valproate in patients of age 60 years and older with Type I Bipolar mania or hypomania. This multi-site study was conducted at six academic medical centers in the United States and enrolled inpatients and outpatients with a total Young Mania Rating Scale (YMRS) score of 18 or greater. Depressive symptoms were evaluated with the Hamilton Depression Rating Scale (HAM-D) and the Montgomery-Asberg Depression Rating Scale (MADRS). The criterion for at least moderate bipolar depressive symptoms was the European College of Neuropsychopharmacology (ECNP) Consensus Meeting definition of HAM-D 17 total score >20. Eleven percent of patients had mixed symptoms defined by depression scale severity according to ECNP criterion. In the overall sample, total scores on the two depression scales were highly correlated. Total YMRS scores of this mixed symptom group were similar to the remainder of the sample. These preliminary findings suggest that moderate to severe depressive symptoms occur in about one in ten bipolar manic elders. Future studies are needed to further evaluate symptom profiles, clinical correlates, and treatments for bipolar older adults with combined manic and depressive symptoms.

    2007-12-01

    Full Text Available Abstract Background Beck Cognitive Insight Scale (BCIS has been designed for assessment of self-reflection on patients' anomalous experiences and interpretations of own beliefs. The scale has been developed and validated for patients with schizophrenia. We wanted to study the utility of the scale for patients with bipolar disorder. The relationship between the BCIS as a measure of cognitive insight and established methods for assessment of insight of illness was explored in both diagnostic groups. Methods The BCIS self-report inventory was administered to patients with schizophrenia (n = 143, bipolar disorder (n = 92 and controls (n = 64. The 15 items of the inventory form two subscales, self-reflectiveness and self-certainty. Results The internal consistency of the subscales was good for the patient groups and the controls. The mean subscale scores were not significantly different for the three groups. Four items in subscale self-reflectiveness referring to psychotic experiences gave, however, different results in the control subjects. Self-certainty and scores on insight item PANSS correlated significantly in the schizophrenia, but not in the bipolar group. Conclusion BCIS with its two subscales seems applicable for patients with bipolar disorder as well as for patients with schizophrenia. The self-report inventory can also be applied to control subjects if the items referring to psychotic experiences are omitted. In schizophrenia high scores on self-certainty is possibly associated with poor insight of illness. For the bipolar group the subscales are largely independent of traditional insight measures.

    Linkage and fine mapping studies have established that the neuregulin 3 gene (NRG3) is a susceptibility locus for schizophrenia. Association studies of this disorder have implicated NRG3 variants in both psychotic symptoms and attention performance. Psychotic symptoms and cognitive deficits are also frequent features of bipolar disorder. The aims of the present study were to extend analysis of the association between NRG3 and psychotic symptoms and attention in schizophrenia and to determine whether these associations also apply to bipolar disorder. A total of 358 patients with schizophrenia and 111 patients with bipolar disorder were included. Psychotic symptoms were evaluated using the Operational Criteria Checklist for Psychotic Illness (OPCRIT) and attention performance was assessed using the Trail Making Test (TMT). Symptoms and performance scores were then tested for association with the NRG3 variant rs6584400. A significant association was found between the number of rs6584400 minor alleles and the total OPCRIT score for psychotic symptoms in patients with schizophrenia. Moreover, in both schizophrenia and bipolar disorder patients, minor allele carriers of rs6584400 outperformed homozygous major allele carriers in the TMT. The results suggest that rs6584400 is associated with psychotic symptoms and attention performance in schizophrenia. The finding of a significant association between rs6584400 and attention performance in bipolar disorder supports the hypothesis that this NRG3 variant confers genetic susceptibility to cognitive deficits in both schizophrenia and bipolar disorder.

    Beyer, John L; Weisler, Richard H

    2016-03-01

    Suicide behaviors (ideation, attempts, and completions) are unfortunately common in patients with bipolar disorder. It is estimated that 25 to 50% attempt suicide at least once during their lifetime, and 6% to 19% complete suicide. Risk factors include a family history of suicide, previous suicide attempts, younger age of onset, comorbid psychiatric illnesses, and psychological constructs like hopelessness. Pharmacologic treatment may impact suicidal behaviors, either increasing vulnerability or resilience. Clinicians need to be particularly sensitive to their patient's thoughts and beliefs about death, particularly during stressful times of life or when in a depressive/mixed episode of bipolar disorder.

    Full Text Available Abstract Background There is little published guideline or evidence on treating bipolar affective disorder in patients with renal failure having haemodialysis. Case We present two patients with bipolar affective disorder with renal failure having haemodialysis. We used lorazepam in one patient to manage the immediate risk of non-engagement with dialysis. Risperidone was added in the second patient for managing psychotic symptoms. Valproate was started as a mood stabiliser and titrated upwards for long-term management of the illness. Conclusion We discuss the similarities in the two cases and the care plan we used to manage them.

Patients and methods Our study included 66 patients with bipolar I disorder and 64 controls aged 37.9 ± 12.6 and 36.3 ± 18.2 years, respectively. Paraoxonase activity was determined by kinetic methods; high-density lipoprotein cholesterol (c-HDL, low-density lipoprotein cholesterol (c-LDL, triglycerides and total cholesterol were determined by enzymatic methods; apolipoprotein (ApoA1, ApoB and lipoprotein (a (Lp(a were determined by immunoturbidimetry using Konelab 30 equipment (Thermo Scientific. Results Compared with controls, patients had a significantly lower paraoxonase activity and ApoA1 level, and significantly higher total cholesterol, c-LDL and Lp(a level and ApoB/ApoA1 ratio. Furthermore, paraoxonase activity was significantly correlated with c-HDL values (r = 0.5612; P Conclusions Bipolar patients had a significant decrease in paraoxonase activity and perturbations in their lipid profile that contribute to increased risk of cardiovascular diseases. Decrease in this activity was significantly associated with treatment with lithium but not with sociodemographic and clinical characteristics. Therefore, such patients require specific care, particularly with regard to their lipid profile.

    The present article attempts first to provide a historical overview of the concept of temperament,The present article attempts first to provide a historical overview of the concept of temperament,since its foundation by Polybos (4th century B.C.) and the school of Cos, its predominant role in theshaping of the anthropological and humanitarian sciences, until the modern theoretical formulations,such as those proposed by Robert Cloninger and Hagop Akiskal. Secondly, recent literature ispresented, which suggests a strong link of different temperament structures to mental health andpsychopathology. Hans Eysenck (1916-1997) was the first psychologist to establish approaches topersonality differences and to distinguish three dimensions of personality: Neuroticism, Extraversionand Psychotisism. Eysenck was followed by McCrae and Costa who proposed that there are five basicdimensions of personality ("Big Five"). In the mid-1980s, Robert Cloninger developed a distinctivedimensional model of temperament and character traits. Hagop Akiskal emphasized on the affectivecomponents of temperament and their possible connections to mood disorders and creativity.Specifically, temperament assessment seems to help in differentiating between the relationship ofvarious temperaments and the clinical manifestations of bipolar illness. Within the area of mood disorders,specific affective temperaments might constitute vulnerability factors, as well as clinical pictureand illness course modifiers. Viewing mood disorders under this prism gives birth to the concept ofthe bipolar spectrum with major implications for all aspects of mental health research and providingof care. The hyperthymic and the depressive temperaments are related to the more 'classic' bipolarpicture (that is euphoria, grandiose and paranoid thinking, antisocial behavior, psychomotor accelerationand reduced sleep and depressive episodes respectively). On the contrary cyclothymic, anxiousand irritable temperaments are related

    Background: Little is known about the cognitive signature of bipolar disorder (BD) in elderly brains. The neuropsychological features of depressive elderly with early-onset BD are largely unknown. This issue is relevant because cognitive impairment can produce an additional impact on the already compromised functionality of elderly with BD. The aim of this study is to assess executive functions (EFs) in the depressive phase of elderly outpatients with early-onset BD. Methods: Forty-nine elderly outpatients with early-onset BD were assessed with several neuropsychological tests for EF in the depressive phase of the disorder. Results: Executive dysfunction is very common in old age bipolar depression. Thirteen patients (26.5%) had a pseudodementia presentation. The worst performances were observed in the following tests: Trail Making B, Stroop Test 3, Backward Digit Span and Wisconsin Card Sorting Test. Conclusion: Executive dysfunction profile in elderly BD is complex and heterogeneous, but most cases display difficulties in working memory, inhibitory control, mental flexibility, and information processing speed. The performance of elderly with bipolar depression in executive assessment can be divided into two main categories: (1) Single EF domain impairment; and (2) Multiple EF domain impairment with or without a pseudodementia syndrome. Executive dysfunction in old age bipolar depression may be explained by lack of sufficient mental energy to run those cognitive processes that require larger amounts of effort to be performed.

Disturbed marital relationship can directly affect the disease adjustment and the way they face disease outcomes and complications. It may adversely affect physical health, mental health, the quality-of-life and even economic status of individuals. Aim: The aim of this study was to compare the marital adjustment among patients with substance dependence, schizophrenia and bipolar affective disorder. Materials and Methods: The sample consisted of each 30 patients with substance dependence, bipolar affective disorder and schizophrenia, diagnosed as per international classification of diseases-10 diagnostic criteria for research with a minimum duration of illness of 1 year were evaluated using marital adjustment questionnaire. The data was analyzed using parametric and non-parametric statistics. Results: Prevalence of poor marital adjustment in patients with schizophrenia, bipolar affective disorder and substance dependence was 60%, 70% and 50% respectively. There was a significant difference on overall marital adjustment among substance dependence and bipolar affective disorder patients. There was no significant difference on overall marital adjustment among patients with substance dependence and schizophrenia as well as among patients with schizophrenia and bipolar affective disorder. On marital adjustment domains, schizophrenia patients had significantly poor sexual adjustment than substance dependence patients while bipolar affective disorder patients had significantly poor sexual and social adjustment compared with substance dependence patients. Conclusion: Patients with substance dependence have significant better overall marital adjustment compared with bipolar affective disorder patients. Patients with substance dependence have significantly better social and sexual adjustment than patients with bipolar affective disorder as well as significantly better sexual

    Although bariatric surgery has become a recognized treatment for obesity, its utility among patients with severe psychiatric disorders has not been extensively studied. A few studies have reported similar weight loss outcomes in these patients, but psychiatric status after bariatric surgery has been studied only minimally, and it is unknown if exacerbation of the mental illness affects weight loss. The aim of this study was to shed greater light on the issue of serious mental illness and bariatric surgery. Specifically, do patients with a diagnosis of schizophrenia, bipolar I, and bipolar II have poorer weight loss outcomes postbariatric surgery than the general bariatric surgery population? Also, do patients with these diagnoses experience an exacerbation of psychiatric symptoms after bariatric surgery, and if so, is the exacerbation of these disorders linked to poorer weight loss results? Midwest university medical center. A medical record review of approximately 1500 bariatric patients in a Midwest university medical center was conducted to identify those patients with diagnoses of schizophrenia, bipolar I, and bipolar II. Information was gathered on bariatric surgery outcomes and changes in psychiatric status postsurgery. Eighteen patients were identified as undergoing bariatric surgery and having a diagnosis of schizophrenia, bipolar I, or bipolar II. Weight loss in this group was significant and comparable to expected outcomes of absolute weight lost, changes in body mass index, and percentage excess weight loss for patients in the typical bariatric population. Postsurgery psychiatric status was known on 10 patients. All 10 patients experienced some exacerbation of psychiatric problems yet weight loss outcomes were still as expected. Bariatric surgery is a viable obesity treatment option for patients with schizophrenia, bipolar I, and bipolar II disorders. Symptom exacerbations occurred postsurgery, although it is not clear if these were due to the surgery or

    This comprehensive literature review incorporates research studies evaluating the effectiveness of psychotropic medications in children and adolescents with pediatric bipolar disorder. Research articles were obtained using Medline. Open-label studies, prospective and retrospective chart reviews and randomized controlled trials evaluating the effectiveness of medication in pediatric bipolar disorder with greater than ten subjects are included in this article. Antipsychotics, anticonvulsants and lithium as monotherapy, as well as their use in combination treatment, were evaluated to determine their effectiveness in pediatric bipolar disorder. Clinical recommendations of medication and management strategies are made from a synthesis of the data. In addition, adherence concerns caused by adverse effects and nonresponse as they impact physical and mental health are addressed.

    Family history and adversity in childhood are two replicated risk factors for early onset bipolar disorder. However, their combined impact has not been adequately studied. Based on questionnaire data from 968 outpatients with bipolar disorder who gave informed consent, the relationship and interaction of: 1) parental and grandparental total burden of psychiatric illness; and 2) the degree of adversity the patient experienced in childhood on their age of onset of bipolar disorder was examined with multiple regression and illustrated with a heat map. The familial loading and child adversity vulnerability factors were significantly related to age of onset of bipolar and their combined effect was even larger. A heat map showed that at the extremes (none of each factor vs high amounts of both) the average age of onset differed by almost 20 years (mean = 25.8 vs 5.9 years of age). The data were not based on interviews of family members and came from unverified answers on a patient questionnaire. Family loading for psychiatric illness and adversity in childhood combine to have a very large influence on age of onset of bipolar disorder. These variables should be considered in assessment of risk for illness onset in different populations, the need for early intervention, and in the design of studies of primary and secondary prevention.

  11. Life events in bipolar disorder: towards more specific models.

    Johnson, Sheri L

    2005-12-01

    This article reviews the evidence concerning life events as a predictor of symptoms within bipolar disorder. First, key methodological issues in this area are described, and criteria used for including studies in this review are defined. Then findings that negative life events predict worse outcomes within bipolar disorder are reviewed. Beyond general studies on relapse, it is important to differentiate predictors of depression from predictors of mania. When severe negative life events occur, they appear to trigger increases in bipolar depression. Nonetheless, many depressions are unrelated to negative life events and appear to be triggered by other variables. The strongest evidence suggests that negative life events do not trigger mania, except perhaps in certain contexts. Retrospective findings for schedule-disrupting life events as a trigger for manic symptoms await further assessment within a longitudinal study. Life events involving goal attainment do appear to trigger manic symptoms. Overall, it is time to differentiate among specific types of life events, as these different forms of events point towards mechanisms linking stressors with symptom expression. These mechanisms provide clues into ways to integrate the social environment with biological vulnerability (see [Monroe, S.M., & Johnson, S.L.

    Dramatically increasing prevalence rates of bipolar disorder in children and adolescents in the United States have provoked controversy regarding the boundaries of manic symptoms in child and adolescent psychiatry. The serious impact of this ongoing debate on the treatment of affected children is reflected in the concomitant increase in prescription rates for antipsychotic medication. A key question in the debate is whether this increase in bipolar disorder in children and adolescents is based on a better detection of early-onset bipolar disorder—which can present differently in children and adolescents—or whether it is caused by an incorrect assignment of symptoms which overlap with other widely known disorders. So far, most findings suggest that the suspected symptoms, in particular chronic, non-episodic irritability (a mood symptom presenting with easy annoyance, temper tantrums and anger) do not constitute a developmental presentation of childhood bipolar disorder. Additional research based on prospective, longitudinal studies is needed to further clarify the developmental trajectories of bipolar disorder and the diagnostic status of chronic, non-episodic irritability.

    Genetic factors contribute to schizophrenia and bipolar disorder, and linkage and association studies have been successful in identifying several candidate genes. However these genes explain only a very small part of the total population risk and the psychoses appear to be very heterogeneous with several models of genetic inheritance relevant to different groups of patients, including some cases caused by multiple common genetic variants, while others are single gene disorders. Studying chromosomal abnormalities is a useful strategy for identifying genes in illness, and patients with both mental retardation and psychosis form a special group where large chromosomal abnormalities detected by routine cytogenetic analysis are more prevalent than in patients with schizophrenia or bipolar disorder alone, or in the general population. Studying these patients provides valuable opportunities to identify genes contributing to psychoses. This review of the literature on large chromosomal rearrangements in patients with mental retardation and psychotic illness illustrates how schizophrenia and bipolar phenotypes are associated with a large number of different chromosomal disruptions. Recent genome wide association studies have identified an excess of small chromosomal deletions and duplications in schizophrenia, adding further support to the importance of chromosomal structural variation in psychotic illness. The genes GRIK4 and NPAS3, each associated with psychosis in patients with mental retardation are discussed to illustrate the value of rare cytogenetic events as a means to signpost neurobiological pathways of general importance for illness in the wider population.

    Bipolar disorder is a complex neuropsychiatric disorder that is characterized by intermittent episodes of mania and depression; without treatment, 15% of patients commit suicide. Hence, it has been ranked by the World Health Organization as a top disorder of morbidity and lost productivity. Previous neuropathological studies have revealed a series of alterations in the brains of patients with bipolar disorder or animal models, such as reduced glial cell number in the prefrontal cortex of patients, upregulated activities of the protein kinase A and C pathways and changes in neurotransmission. However, the roles and causation of these changes in bipolar disorder have been too complex to exactly determine the pathology of the disease. Furthermore, although some patients show remarkable improvement with lithium treatment for yet unknown reasons, others are refractory to lithium treatment. Therefore, developing an accurate and powerful biological model for bipolar disorder has been a challenge. The introduction of induced pluripotent stem-cell (iPSC) technology has provided a new approach. Here we have developed an iPSC model for human bipolar disorder and investigated the cellular phenotypes of hippocampal dentate gyrus-like neurons derived from iPSCs of patients with bipolar disorder. Guided by RNA sequencing expression profiling, we have detected mitochondrial abnormalities in young neurons from patients with bipolar disorder by using mitochondrial assays; in addition, using both patch-clamp recording and somatic Ca(2+) imaging, we have observed hyperactive action-potential firing. This hyperexcitability phenotype of young neurons in bipolar disorder was selectively reversed by lithium treatment only in neurons derived from patients who also responded to lithium treatment. Therefore, hyperexcitability is one early endophenotype of bipolar disorder, and our model of iPSCs in this disease might be useful in developing new therapies and drugs aimed at its clinical

    The aim of this study was to investigate proton magnetic resonance spectroscopy metabolite values in the medial prefrontal cortex of individuals with euthymic bipolar disorder. The subjects consisted of 15 patients with euthymic bipolar disorder type I and 15 healthy controls. We performed proton magnetic resonance spectroscopy of the bilateral medial prefrontal cortex and measured levels of N-acetyl aspartate, choline and creatine. Levels of these three metabolites in the medial prefrontal cortex were found to be lower in patients with bipolar disorder compared with healthy controls. A positive correlation was found between illness duration and choline levels in the right medial prefrontal cortex. Our study suggests that during the euthymic period, there are abnormalities in cellular energy and membrane phospholipid metabolism in the medial prefrontal cortex, and that this may impair neuronal activity and integrity.

    Full Text Available Bipolar disorder (BD is a chronic disorder which usually has its onset in early adulthood. At one end of the spectrum is depression and at other is mania. Like many psychiatric illnesses, it is not treatable but its symptoms are completely manageable with medications. Commonly used drugs are mood stabilizers and atypical antipsychotics along with adjunctive medications such as anxiolytics and antidepressants. In general, a combination of these drugs is used for treatment. These drugs have significant adverse effects which add to the burden of the disease. Presently, there are 11 US Food and Drug Administration - approved drugs for management of acute mania, 3 for bipolar depression and 7 for bipolar maintenance. This review article details the use of these drugs in BD. [Int J Basic Clin Pharmacol 2015; 4(4.000: 623-631

    Full Text Available Despite high mortality associated with serious mental illness, risk of acute myocardial infarction (AMI remains unclear, especially for patients with bipolar disorder. The main objective was to investigate the relative risk of AMI associated with schizophrenia and bipolar disorders in a national sample.Using nationwide administrative data, an 11-year historic cohort study was assembled, comprised of cases aged 18 and above who had received a diagnosis of schizophrenia or bipolar disorder, compared to a random sample of all other adults excluding those with diagnoses of serious mental illness. Incident AMI as a primary diagnosis was ascertained. Hazard ratios stratified by age and gender were calculated and Cox regression models were used to adjust for other covariates.A total of 70,225 people with schizophrenia or bipolar disorder and 207,592 people without serious mental illness were compared. Hazard ratios in men adjusted for age, income and urbanization were 1.15 (95% CI 1.01~1.32 for schizophrenia and 1.37 (1.08~1.73for bipolar disorder, and in women, 1.85 (1.58~2.18 and 1.88(1.47~2.41 respectively. Further adjustment for treated hypertension, diabetes and hyperlipidaemia attenuated the hazard ratio for men with schizophrenia but not the other comparison groups. Hazard ratios were significantly stronger in women than men and were stronger in younger compared to older age groups for both disorders; however, gender modification was only significant in people with schizophrenia, and age modification only significant in people with bipolar disorder.In this large national sample, schizophrenia and bipolar disorder were associated with raised risk of AMI in women and in the younger age groups although showed differences in potential confounding and modifying factors.

    Changes in speech have been suggested as sensitive and valid measures of depression and mania in bipolar disorder. The present study aimed at investigating (1) voice features collected during phone calls as objective markers of affective states in bipolar disorder and (2) if combining voice features with automatically generated objective smartphone data on behavioral activities (for example, number of text messages and phone calls per day) and electronic self-monitored data (mood) on illness activity would increase the accuracy as a marker of affective states. Using smartphones, voice features, automatically generated objective smartphone data on behavioral activities and electronic self-monitored data were collected from 28 outpatients with bipolar disorder in naturalistic settings on a daily basis during a period of 12 weeks. Depressive and manic symptoms were assessed using the Hamilton Depression Rating Scale 17-item and the Young Mania Rating Scale, respectively, by a researcher blinded to smartphone data. Data were analyzed using random forest algorithms. Affective states were classified using voice features extracted during everyday life phone calls. Voice features were found to be more accurate, sensitive and specific in the classification of manic or mixed states with an area under the curve (AUC)=0.89 compared with an AUC=0.78 for the classification of depressive states. Combining voice features with automatically generated objective smartphone data on behavioral activities and electronic self-monitored data increased the accuracy, sensitivity and specificity of classification of affective states slightly. Voice features collected in naturalistic settings using smartphones may be used as objective state markers in patients with bipolar disorder.

  4. Mixed States in Bipolar Disorder: Etiology, Pathogenesis and Treatment

    Science.gov (United States)

    2017-01-01

    Many bipolar disorder patients exhibit mixed affective states, which portend a generally more severe illness course and treatment resistance. In the previous renditions of Diagnostic and Statistical Manual mixed states were narrowly defined in the context of bipolar I disorder, but with the advent of DSM-5 the term “mixed episode” was dropped and replaced by “mixed features” specifier which could be broadly applied to manic, hypomanic and depressive episodes in both the bipolar spectrum and major depressive disorders. This paradigm shift reflected their significance in the prognosis and overall management of mood disorders, so that the clinicians should thoroughly familiarize themselves with the contemporary notions surrounding these conditions. The purpose of this manuscript is to bring to light the current conceptualizations regarding the etiology, pathogenesis and treatment of mixed states. To achieve this goal, in June 2016 an extensive literature search was undertaken using the PubMed database. Some exploratory terms utilized included “mixed states”, “mixed episodes”, “switching”, “rapid cycling” cross referenced with “bipolar disorder”. Focusing on the most relevant and up to date studies, it was revealed that mixed states result from genetic susceptibility in the circadian and dopamine neurotransmission apparatuses and disturbance in the intricate catecholamine-acetylcholine neurotransmission balance which leads to mood fluctuations. The management of mixed states is challenging with atypical antipsychotics, newer anticonvulsants and electroconvulsive therapy emerging as the foremost treatment options. In conclusion, while progress has been made in the neurobiological understanding of mixed states, the currently available therapeutic modalities have only shown limited effectiveness. PMID:28184334

    Early onset (pediatric) bipolar disorders are still an issue of much controversy due to several clinical particularities of the thymic episodes at this age. To date, there is indeed no consensus regarding the prevalence of bipolar disorders before puberty. Diagnosis criteria in children and young adolescents remain thus elusive. The purpose of this review is to provide an overview of this issue. The idea of continuity, from childhood to adulthood, in bipolar disorders also raises important questions regarding predictive factors of bipolar disorders in adults. Studies on the childhood of bipolar adults, as well as studies on the children of bipolar parents will be reviewed, in an attempt to identify the psychopathological substrates of bipolar disorders.

    The treatment of bipolar depression requires the resolution of depression and the establishment of mood stability. A basic problem is that the treatments used in treating bipolar depression were developed and proven effective for other disease states: antidepressants for unipolar depression, and mood stabilizers for mania. The panel addressed four unresolved questions regarding depression in relation to bipolar disorder: (1) the relative effectiveness of different antidepressant treatments; (2) the relative likelihood of mood destabilization with different antidepressant treatments; (3) the effectiveness and role of mood-stabilizing medicines as antidepressants; and (4) the optimal approach to mixed states. The selection of an antidepressant depends both on its relative lack of mania- or hypomania-provoking potential and on its effectiveness against bipolar depression. There is little definitive evidence distinguishing effectiveness of the major groups of antidepressive agents, so side-effect profiles and pharmacokinetics are major considerations. The underlying bipolar disorder should be treated with mood stabilizers started simultaneously with any antidepressive treatments. Lithium, divalproex sodium and carbamazepine have all been found to be helpful, to some extent, in treating bipolar depressive episodes as well as for long-term mood stabilization. There is little evidence for long-term benefits of antidepressive agents in bipolar disorder, and some evidence that they may destabilize the disorder. Therefore, in contrast to the long-term use of mood-stabilizers, antidepressant use is recommended on a temporary basis. The duration of antidepressant treatment is determined by past history in terms of liability for mood destabilization, and by the ability of the patient to tolerate gradual antidepressant discontinuation without return of depression. Mixed states, where symptoms of depression and mania coexist, are regarded as a predictor of relatively poor

    2007-10-01

    Full Text Available Abstract The aim of this paper is to provide a systematic review of the literature examining the epidemiology, outcome, and treatment of patients with bipolar disorder and co-occurring substance use disorders (SUDs. Articles for this review were initially selected via a comprehensive Medline search and further studies were obtained from the references in these articles. Given the lack of research in this field, all relevant studies except case reports were included. Prior epidemiological research has consistently shown that substance use disorders (SUDs are extremely common in bipolar I and II disorders. The lifetime prevalence of SUDs is at least 40% in bipolar I patients. Alcohol and cannabis are the substances most often abused, followed by cocaine and then opioids. Research has consistently shown that co-occurring SUDs are correlated with negative effects on illness outcome including more frequent and prolonged affective episodes, decreased compliance with treatment, a lower quality of life, and increased suicidal behavior. Recent research on the causal relationship between the two disorders suggests that a subgroup of bipolar patients may develop a relatively milder form of affective illness that is expressed only after extended exposure to alcohol abuse. There has been very little treatment research specifically targeting this population. Three open label medication trials provide limited evidence that quetiapine, aripiprazole, and lamotrigine may be effective in treating affective and substance use symptoms in bipolar patients with cocaine dependence and that aripiprazole may also be helpful in patients with alcohol use disorders. The two placebo controlled trials to date suggest that valproate given as an adjunct to lithium in bipolar patients with co-occurring alcohol dependence improves both mood and alcohol use symptoms and that lithium treatment in bipolar adolescents improves mood and SUD symptoms. Given the high rate of SUD co

    Bipolar disorder affects up to one in 25 individuals and identification of early risk indicators of negative outcomes could facilitate early detection of patients with greatest clinical needs and risk. We aimed to investigate the association between childhood maltreatment and key negative outcomes in patients with bipolar disorder. For this systematic review and meta-analysis we searched MEDLINE, PsycINFO, and Embase to identify articles published before Jan 1, 2015, examining the association of maltreatment (physical, sexual, or emotional abuse, neglect, or family conflict) before age 18 years with clinical features and course of illness in bipolar disorder. Data were extracted from published reports and any missing information was requested from investigators. We did 12 independent random-effects meta-analyses to quantify the associations between childhood maltreatment and course of illness or clinical features. We initially identified 527 records and after unsuitable studies were removed, our search yielded 148 publications of which 30 were used in the meta-analysis. Patients with bipolar disorder and history of childhood maltreatment had greater mania severity (six studies, 780 participants; odds ratio [OR] 2·02, 95% CI 1·21-3·39, p=0·008), greater depression severity (eight studies, 1007 participants; 1·57, 1·25-1·99, p=0·0001), greater psychosis severity (seven studies, 1494 participants; 1·49, 1·10-2·04, p=0·011), higher risk of comorbidity with post-traumatic stress disorder (eight studies, 2494 participants; 3·60, 2·45-5·30, pchildhood maltreatment. Overall, these associations were not explained by publication bias, undue effects of individual studies, or variation in study quality.

    2015-01-01

    Full Text Available Neuroinflammation has been proposed as a strong biological factor underlying the development of neuropsychiatric diseases. A role for dysregulation of the immune system was initially suggested in depressive disorders and subsequently extended to other illnesses, including bipolar disorder (BD. Indeed, there is growing evidence confirming the presence of a generalized pro-inflammatory state in BD patients, involving alterations in cytokine, acute-phase proteins, and complement factor secretion, white blood cell differentiation, microglial activation, arachidonic acid signaling pathways, and increased oxidative stress markers. Medications commonly used to treat BD, such as lithium, antiepileptics and antipsychotics, show some immunoregulatory activity both in vitro and in vivo. The aim of our study was to review the role of different inflammatory mechanisms, specifically in the development of excitatory symptoms, via a systematic PubMed search of the literature. Despite the high variability of results among studies, we found evidence indicating specific alterations of the inflammatory response during manic and mixed states of BD. These findings may help to clarify some of the complex mechanisms underlying the development of excitatory symptoms and suggest a potential role for drugs targeting the inflammatory system as new therapeutic options.

    Emission from the 4u = 1 - 0 S(1) line of molecular hydrogen has been mapped in the bipolar outflow NGC 2071. The line emission peaks at six positions distributed irregularly along the two lobes, which extend over a distance of {similar to} 1 pc. These lobes are parallel to, but offset {similar to} 20 arcsec from, the lobes of high-velocity CO line emission. Spectra from 2.1 to 2.45 {mu}m of the H{sub 2} emission lines are typical of shock-excited emission. The total H{sub 2} line luminosity is estimated to be {similar to} 4.5 time the solar luminosity. Profiles of the 1-0 S(1) line are relatively narrow (< 30 km s{sup -1} FWHM) for shocked gas. The peak velocity varies systematically across the source, in a manner consistent with the observed bipolarity of the millimetre-wave CO line emission. (author).

    Background: Increased inflammatory markers and oxidative stress have been reported in serum among patients with bipolar disorder (BD). The aim of this study is to assess whether biochemical changes in the serum of patients induces neurotoxicity in neuronal cell cultures. Methods: We challenged the retinoic acid-differentiated human neuroblastoma SH-SY5Y cells with the serum of BD patients at early and late stages of illness and assessed neurite density and cell viability as neurotoxic endpoints. Results: Decreased neurite density was found in neurons treated with the serum of patients, mostly patients at late stages of illness. Also, neurons challenged with the serum of late-stage patients showed a significant decrease in cell viability. Conclusions: Our findings showed that the serum of patients with bipolar disorder induced a decrease in neurite density and cell viability in neuronal cultures. PMID:27207915

    Patients with Bipolar disorder smoke more than the general population. Smoking negatively impacts mortality and clinical course in Bipolar disorder patients. Prior studies have shown contradictory results regarding the impact of psychosis on smoking behavior in Bipolar disorder. We analyzed a large sample of Bipolar disorder and Schizoaffective disorder, Bipolar Type patients and predicted those with a history of psychosis would be more likely to be nicotine dependent. Data from subjects and controls were collected from the Genomic Psychiatry Cohort (GPC). Subjects were diagnosed with Bipolar disorder without psychosis (N = 610), Bipolar disorder with psychosis (N = 1544). Participants were classified with or without nicotine dependence. Diagnostic groups were compared to controls (N = 10065) using logistic regression. Among smokers (N = 6157), those with Bipolar disorder had an increased risk of nicotine dependence (OR = 2.5; P < 0.0001). Patients with Bipolar disorder with psychosis were more likely to be dependent than Bipolar disorder patients without psychosis (OR = 1.3; P = 0.03). Schizoaffective disorder, Bipolar Type patients had more risk of nicotine dependence when compared to Bipolar disorder patients with or without psychosis (OR = 1.2; P = 0.02). Bipolar disorder patients experiencing more severity of psychosis have more risk of nicotine dependence. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    Background Women with bipolar disorder are at increased risk of having a severe episode of illness associated with childbirth. Aims To explore the factors that influence the decision-making of women with bipolar disorder regarding pregnancy and childbirth. Method Qualitative study with a purposive sample of women with bipolar disorder considering pregnancy, or currently or previously pregnant, supplemented by data from an online forum. Data were analysed using thematic analysis. Results Twenty-one women with bipolar disorder from an NHS organisation were interviewed, and data were used from 50 women’s comments via the online forum of the UK’s national bipolar charity. The centrality of motherhood, social and economic contextual factors, stigma and fear were major themes. Within these themes, new findings included women considering an elective Caesarian section in an attempt to avoid the deleterious effects of a long labour and loss of sleep, or trying to avoid the risks of pregnancy altogether by means of adoption or surrogacy. Conclusions This study highlights the information needs of women with bipolar disorder, both pre-conception and when childbearing, and the need for improved training for all health professionals working with women with bipolar disorder of childbearing age to reduce stigmatising attitudes and increase knowledge of the evidence base on treatment in the perinatal period.

    2012-01-01

    Background Pathophysiological models of bipolar disorder postulate that mood dysregulation arises from fronto-limbic dysfunction, marked by reduced prefrontal cortex (PFC) inhibitory control. This may occur both due to disruptions within PFC networks and abnormal inhibition over subcortical structures involved in emotional processing. However, no study has examined global PFC dysconnectivity in bipolar disorder and tested if regions with within-PFC dysconnectivity also exhibit fronto-limbic connectivity deficits. Further, no study has investigated whether such connectivity disruptions differ for bipolar patients with psychosis history, who may exhibit a more severe clinical course. Methods We collected resting-state fMRI at 3T in 68 remitted bipolar I patients (34 with psychosis history) and 51 demographically-matched healthy participants. We employed a recently developed Global Brain Connectivity method, restricted to PFC (rGBC). We also independently tested connectivity between anatomically-defined amygdala and PFC. Results Bipolar patients exhibited reduced medial PFC (mPFC) rGBC, increased amygdala-MPFC connectivity, and reduced connectivity between amygdala and dorso-lateral PFC. All effects were driven by psychosis history. Moreover, the magnitude of observed effects was significantly associated with lifetime psychotic symptom severity. Conclusions This convergence between rGBC, seed-based amygdala findings and symptom severity analyses highlights that mPFC, a core emotion regulation region, exhibits both within-PFC dysconnectivity and connectivity abnormalities with limbic structures in bipolar illness. Furthermore, lateral PFC dysconnectivity in patients with psychosis history converges with published work in schizophrenia, indicating possible shared risk factors. Observed dysconnectivity in remitted patients suggests a bipolar trait characteristic and may constitute a risk factor for phasic features of the disorder. PMID:22980587

  4. Six-Month Outcome in Bipolar Spectrum Alcoholics Treated with Acamprosate after Detoxification: A Retrospective Study

    Directory of Open Access Journals (Sweden)

    Angelo Giovanni Icro Maremmani

    2014-12-01

    Full Text Available Background: Glutamate system is modified by ethanol and contributes both to the euphoric and the dysphoric consequences of intoxication, but there is now growing evidence that the glutamatergic system also plays a central role in the neurobiology and treatment of mood disorders, including major depressive disorders and bipolar disorders. We speculate that, using acamprosate, patients with bipolar depression (BIP-A can take advantage of the anti-glutamate effect of acamprosate to “survive” in treatment longer than peers suffering from non-bipolar depression (NBIP-A after detoxification. Method: We retrospectively evaluated the efficacy of a long-term (six-month acamprosate treatment, after alcohol detoxification, in 41 patients (19 males and 22 females, who could be classified as depressed alcoholics, while taking into account the presence/absence of bipolarity. Results: During the period of observation most NBIP-A patients relapsed, whereas a majority of BIP-A patients were still in treatment at the end of their period of observation. The cumulative proportion of ‘surviving’ patients was significantly higher in BIP-A patients, but this finding was not related to gender or to other demographic or clinically investigated characteristics. The treatment time effect was significant in both subgroups. The treatment time-group effect was significant (and significantly better for bipolar patients on account of changes in the severity of their illness. Limitations: Retrospective methodology and the lack of DSM criteria in diagnosing bipolarity. Conclusions: Bipolarity seems to be correlated with the efficacy of acamprosate treatment in inducing patients to refrain from alcohol use after detoxification (while avoiding relapses in depressed alcoholics. Placebo-controlled clinical trials are now warranted to check the validity of this hypothesis.

  5. How genes and environmental factors determine the different neurodevelopmental trajectories of schizophrenia and bipolar disorder.

    2012-03-01

    The debate endures as to whether schizophrenia and bipolar disorder are separate entities or different manifestations of a single underlying pathological process. Here, we argue that this sterile argument obscures the fact that the truth lies somewhere in between. Thus, recent studies support a model whereby, on a background of some shared genetic liability for both disorders, patients with schizophrenia have been subject to additional genetic and/or environmental factors that impair neurodevelopment; for example, copy number variants and obstetric complications are associated with schizophrenia but not with bipolar disorder. As a result, children destined to develop schizophrenia show an excess of neuromotor delays and cognitive difficulties while those who later develop bipolar disorder perform at least as well as the general population. In keeping with this model, cognitive impairments and brain structural abnormalities are present at first onset of schizophrenia but not in the early stages of bipolar disorder. However, with repeated episodes of illness, cognitive and brain structural abnormalities accumulate in both schizophrenia and bipolar disorder, thus clouding the picture.

    2017-01-01

    The etiology and clinical course of bipolar disorder are considered to be determined by genetic and environmental factors. Although the kindling hypothesis emphasizes the impact of environmental factors on initial onset, their connection to the outcome and clinical course have been poorly established. Hence, there have been numerous research efforts to investigate the impact of environmental factors on the clinical course of illness. Our aim is to outline recent research on the impact of environmental determinants on the clinical course of bipolar disorder. We carried out a computer-aided search to find publications on an association between environmental factors, life events, and the clinical course of bipolar disorder. Publications in the reference lists of suitable papers have also been taken into consideration. We performed a narrative overview on all eligible publications. The available body of data supports an association between environmental factors and the clinical course of bipolar disorder. These factors comprise prenatal, early-life, and entire lifespan aspects. Given varying sample sizes and several methodological limitations, the reported quality and extent of the association between environmental factors and the clinical course of bipolar disorder should be interpreted with utmost caution. Systematic longitudinal long-term follow-up trials are needed to obtain a clearer and more robust picture.

    Background Relatively little is known about psychological predictors of the onset of mania among individuals with bipolar disorder, particularly during episodes of depression. In the present study we investigated attributional style as a predictor of onset of hypomanic, manic or mixed episodes among bipolar adults receiving psychosocial treatment for depression. We hypothesized that “extreme” (i.e., excessively pessimistic or optimistic) attributions would predict a greater likelihood of developing an episode of mood elevation. Method Outpatients with DSM-IV bipolar I or II disorder (N=105) enrolled in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) were randomly allocated to one of three types of intensive psychotherapy for depression or a brief psychoeducational intervention. Patients completed a measure of attributional style at baseline and were followed prospectively for up to one year. All analyses were by intent to treat. Results Logistic regressions and Cox proportional hazards models indicated that extreme (both positively- and negatively-valenced) attributions predicted a higher likelihood of (and shorter time until) transition from depression to a (hypo)manic or mixed episode (ps bipolar illness, and who may benefit from treatments that introduce greater cognitive flexibility.

    Type 2 diabetes mellitus (T2DM) rates are three times higher in patients with bipolar disorder (BD), compared to the general population. This is a major contributing factor to the elevated risk of cardiovascular mortality, the leading cause of death in bipolar patients. There may be shared pathophysiology linking the two disorders, including hypothalamic-pituitary-adrenal and mitochondrial dysfunction, common genetic links, and epigenetic interactions. Life-style, phenomenology of bipolar symptoms, and adverse effects of pharmacotherapy may be contributing factors. Patients with BD and T2DM have a more severe course of illness and are more refractory to treatment. Control of their diabetes is poorer when compared to diabetics without BD, and an existing disparity in medical care may be partly responsible. Glucose abnormalities in bipolar patients need to be screened for and treated. Metformin appears to have the best benefit/risk ratio, and the dipeptidyl peptidase-4 inhibitors and glucagon-like peptide-1 receptor agonists and analogues also appear promising, although these agents have not been specifically studied in populations with mood disorders. Physicians need to be aware of the increased risk for T2DM and cardiovascular disease in bipolar patients, and appropriate prevention, screening, case finding, and treatment is recommended.

    Lithium has been the gold standard in treating bipolar disorder. In recent years, the use of lithium seems to be diminished although it is well tolerated among the bipolar disorder patients. This study aimed to evaluate the efficacy and tolerability of lithium as well as to determine factors associated with lithium response among patient with bipolar disorder. A retrospective study was done in a tertiary care hospital in Malaysia which included 47 bipolar disorder patients that were prescribed with lithium maintenance therapy in the time frame of January 2009 until December 2013. Of all the baseline characteristics tested, only psychotic feature differentiated lithium monotherapy group and combination therapy group significantly (χ(2)=4.732, p=0.03). When compared to period before lithium maintenance, all outcome measures (i.e. annual relapse rate, proportion time spent ill and duration of mood episode) showed significant improvement after lithium maintenance in both treatment groups. Lithium discontinuation only occurred in five cases of adverse effects. Predominant depressive mood episode before lithium maintenance (OR=0.159, p=0.033) and first euthymic interval after lithium maintenance (OR=1.109, p=0.047) significantly predicted lithium response. Lithium significantly reduced the frequency and time spent in relapse in patients with bipolar disorder. Predominant depressive mood polarity before lithium maintenance and longer first euthymic interval after lithium maintenance had been identified to predict lithium response significantly.

    Nationally representative data from the 2007 National Health Interview Survey (NHIS) were used to compare HIV testing prevalence among US adults with mental illness (schizophrenia spectrum disorder, bipolar disorder, depression, and/or anxiety) to those without, providing an update of prior work using 1999 and 2002 NHIS data. Logistic regression modeling was used to estimate the probability of ever being tested for HIV by mental illness status, adjusting for age, sex, race/ethnicity, marital status, substance abuse, excessive alcohol or tobacco use, and HIV risk factors. Based on data from 21,785 respondents, 15% of adults had a psychiatric disorder and 37% ever had an HIV test. Persons with schizophrenia (64%), bipolar disorder (63%), and depression and/or anxiety (47%) were more likely to report ever being tested for HIV than those without mental illness (35%). In multivariable models, individuals reporting schizophrenia (adjusted prevalence ratio=1.68, 95% confidence interval=1.33-2.13), bipolar disease (1.58, 1.39-1.81), and depression and/or anxiety (1.31, 1.25-1.38) were more likely to be tested for HIV than persons without these diagnoses. Similar to previous analyses, persons with mental illness were more likely to have been tested than those without mental illness. However, the elevated prevalence of HIV in populations with mental illness suggests that high levels of testing along with other prevention efforts are needed.

    Background Bipolar disorder (BD) is a severe, familial psychiatric condition. Progress in understanding the aetiology of BD has been hampered by substantial phenotypic and genetic heterogeneity. We sought to mitigate these confounders by studying a multi-generational family multiply affected by BD and major depressive disorder (MDD), who carry an illness-linked haplotype on chromosome 4p. Within a family, aetiological heterogeneity is likely to be reduced, thus conferring greater power to det...

    Despite the high morbidity and mortality associated with bipolar depression, the optimal treatment for this phase is still a matter of debate. The aim of the current review was to provide updated evidence about the efficacy and tolerability of anticonvulsants in the treatment of acute bipolar depression. A comprehensive review of randomized controlled trials (RCTs) evaluating the use of anticonvulsants for the treatment of acute bipolar depression up to June 2011 was conducted by means of the PubMed-Medline database. Eligibility criteria included active comparator-controlled or placebo-controlled randomized studies involving monotherapy or combination therapy. A total of 18 RCTs fulfilled the inclusion criteria. Studies supported the efficacy of divalproex as monotherapy in acute bipolar depression but small sample size was a common methodological limitation. Findings were inconclusive for lamotrigine and carbamazepine although overall lamotrigine may have a beneficial but modest effect. Negative results were found for levetiracetam and gabapentin but the evidence base on these agents is scant. All anticonvulsants were generally well tolerated. No double-blind RCTs were found for the use of other anticonvulsants such as oxcarbazepine, licarbazepine, zonisamide, retigabine, pregabalin, tiagabine, felbamate and vigabatrine in the acute treatment of bipolar depression. To sum up, taking into consideration the efficacy and tolerability profiles of anticonvulsants, current evidence supports the use of divalproex and lamotrigine in the treatment of acute bipolar depression. However, available data for most other anticonvulsants are inconclusive and further RCTs with larger sample sizes are needed before drawing firm conclusions.

    2015-01-01

    Treating pregnant women with bipolar disorder is among the most challenging clinical endeavors. Patients and clinicians are faced with difficult choices at every turn, and no approach is without risk. Stopping effective pharmacotherapy during pregnancy exposes the patient and her baby to potential harms related to bipolar relapses and residual mood symptom-related dysfunction. Continuing effective pharmacotherapy during pregnancy may prevent these occurrences for many; however, some of the most effective pharmacotherapies (such as valproate) have been associated with the occurrence of congenital malformations or other adverse neonatal effects in offspring. Very little is known about the reproductive safety profile and clinical effectiveness of atypical antipsychotic drugs when used to treat bipolar disorder during pregnancy. In this paper, we provide a clinically focused review of the available information on potential maternal and fetal risks of untreated or undertreated maternal bipolar disorder during pregnancy, the effectiveness of interventions for bipolar disorder management during pregnancy, and potential obstetric, fetal, and neonatal risks associated with core foundational pharmacotherapies for bipolar disorder.

  18. The nature of the association between childhood ADHD and the development of bipolar disorder: a review of prospective high-risk studies.

    Duffy, Anne

    2012-12-01

    The author reviewed prospective longitudinal studies of the offspring of parents with bipolar disorder to inform our understanding of the nature of the association between childhood ADHD and the risk of developing bipolar disorder in adolescence and young adulthood. A literature review of published prospective cohort studies of the offspring of bipolar parents since 1985 was undertaken using a comprehensive search strategy in several electronic databases. The author provides a qualitative synthesis of results focusing on ADHD and the association with bipolar disorder in prospectively assessed high-risk offspring. These results are discussed in light of findings from other prospective epidemiological and clinical cohort studies. From the reviewed high-risk studies, evidence suggests that the clinical diagnosis of childhood ADHD is not a reliable predictor of the development of bipolar disorder. However, the author found evidence that symptoms of inattention may be part of a mixed clinical presentation during the early stages of evolving bipolar disorder in high-risk offspring, appearing alongside anxiety and depressive symptoms. The author also found preliminary evidence that childhood ADHD may form part of a neurodevelopmental phenotype in offspring at risk for developing a subtype of bipolar disorder unresponsive to lithium stabilization. While childhood ADHD does not appear to be part of the typical developmental illness trajectory of bipolar disorder, subjective problems with attention can form part of the early course, while neurodevelopmental abnormalities may be antecedents in a subgroup of high-risk children.

    A bipolar pulse forming transmission line module and system for linear induction accelerators having first, second, third, and fourth planar conductors which form a sequentially arranged interleaved stack having opposing first and second ends, with dielectric layers between the conductors. The first and second planar conductors are connected to each other at the first end, and the first and fourth planar conductors are connected to each other at the second end via a shorting plate. The third planar conductor is electrically connectable to a high voltage source, and an internal switch functions to short at the first end a high voltage from the third planar conductor to the fourth planar conductor to produce a bipolar pulse at the acceleration axis with a zero net time integral. Improved access to the switch is enabled by an aperture through the shorting plate and the proximity of the aperture to the switch.

    A role for circadian rhythm abnormalities in the pathogenesis of bipolar disorder (BD) has been suggested. The present study assessed circadian preference, a subjective preference for activities in the morning or evening related to chronotype. The sample was comprised of 81 outpatients with BD in remission and 79 control subjects. Circadian preference was derived from an interview evaluating biological rhythms and sleep pattern from the Pittsburgh Sleep Quality Index. Patients were significantly more likely to have an evening preference than control subjects. Circadian preference was also associated with sleep latency. The association of evening preference and longer sleep latency may be related to the frequent clinical observation of a sleep/wake cycle reversal in bipolar disorder.

    Traumatic stress disorders are prevalent in patients with schizophrenia and bipolar disorder. However, there is a lack of prospective longitudinal studies investigating the risk of severe mental illness for people diagnosed with traumatic stress disorders. We aimed to assess if patients with acute stress reaction (ASR) or post-traumatic stress disorder (PTSD) are at increased risk of schizophrenia spectrum disorders or bipolar disorder. We performed a prospective cohort study covering the entire Danish population including information on inpatient and outpatient mental hospitals over 2 decades. Predictors were in- or outpatient diagnoses of ASR or PTSD. We calculated incidence rate ratios (IRR) with 95% CIs of schizophrenia, schizophrenia spectrum disorder, and bipolar disorder. Persons with a traumatic stress disorder had a significantly increased risk of schizophrenia (IRR 3.80, CI 2.33-5.80), schizophrenia spectrum disorder (IRR 2.34, CI 1.46-3.53), and bipolar disorder (IRR 4.22, CI 2.25-7.13). Risks were highest in the first year after diagnosis of the traumatic stress disorder and remained significantly elevated after more than 5 years. Mental illness in a parent could not explain the association. Our findings support an association between diagnosed traumatic stress disorders and subsequent schizophrenia spectrum disorder or bipolar disorder. If replicated, this may increase clinical focus on patients with traumatic stress disorders. © The Author 2016.

  8. Diagnosing bipolar disorder in children and adolescents.

    Science.gov (United States)

    Chang, Kiki D

    2009-11-01

    Pediatric-onset bipolar disorder is common but often difficult to diagnose in younger patients. Clinicians should be sure to establish the presence of a full manic episode to make the diagnosis of bipolar I disorder. Because adult criteria are used for children and adolescents, clinicians also should be aware of developmental norms that can help to make an accurate diagnosis. Bipolar disorder NOS and other disorders in children and adolescents may be prodromal states for bipolar disorder, especially in the presence of a positive family history.

    For decades, lithium and anticonvulsants have been widely used in the treatment of bipolar disorder. Their efficacy in the treatment of mania is recognized. These drugs have been initially evaluated in old and methodologically heterogeneous studies. Their efficacy in bipolar depression has not always been confirmed in more recent and methodologically more reliable studies. Thus, lithium's efficacy as monotherapy was challenged by the study of Young (2008) that showed a lack of efficacy compared with placebo in the treatment of bipolar depression. In two recent meta-analyses, valproate has shown a modest efficacy in the treatment of bipolar depression. As for lithium, valproate appeared to have a larger antimanic effect for acute phase and prophylaxis of bipolar disorder. In contrast, lamotrigine is more effective on the depressive pole of bipolar disorder with better evidence for the prevention of depressive recurrences. The guidelines include these recent studies and recommend lamotrigine as a first-line treatment of bipolar depression and for maintenance treatment. Because of more discordant data concerning lithium and valproate, these two drugs are placed either as first or as second line treatment of bipolar depression. The different safety/efficacy ratios of mood stabilizers underlie the complementarity and the importance of combination between them, or with some second-generation antipsychotics, in the treatment of patients with bipolar disorder.

    Family history and traumatic experiences are factors linked to bipolar disorder. It is known that the lifetime risk of bipolar disorder in relatives of a bipolar proband are 5-10% for first degree relatives and 40-70% for monozygotic co-twins. It is also known that patients with early childhood trauma present earlier onset of bipolar disorder, increased number of manic episodes, and more suicide attempts. We have recently reported that childhood trauma partly mediates the effect of family history on bipolar disorder diagnosis. In light of these findings from the scientific literature, we reviewed the work of British writer Virginia Woolf, who allegedly suffered from bipolar disorder. Her disorder was strongly related to her family background. Moreover, Virginia Woolf was sexually molested by her half siblings for nine years. Her bipolar disorder symptoms presented a pernicious course, associated with hospitalizations, suicidal behavioral, and functional impairment. The concept of neuroprogression has been used to explain the clinical deterioration that takes places in a subgroup of bipolar disorder patients. The examination of Virgina Woolf's biography and art can provide clinicians with important insights about the course of bipolar disorder.

    Full Text Available The comorbidity of bipolar disorder and anxiety disorders is a well known concept. Obsessive-compulsive disorder is the most commonly seen comorbid anxiety disorder in bipolar patients. Some genetic variants, neurotransmitters especially serotonergic systems and second-messenger systems are thought to be responsible for its etiology. Bipolar disorder alters the clinical aspects of obsessive compulsive disorder and is associated with poorer outcome. The determination of comorbidity between bipolar disorder and obsessive compulsive disorder is quite important for appropriate clinical management and treatment.

    Objective Bipolar disorder may be characterized by a hypersensitivity to reward-relevant stimuli, potentially underlying the emotional lability and dysregulation that characterizes the illness. In parallel, research highlights the predominant role of striatal and orbitofrontal cortical (OFC) regions in reward-processing and approach-related affect. We aimed to examine whether bipolar disorder, relative to healthy, participants displayed elevated activity in these regions during reward processing. Methods Twenty-one euthymic bipolar I disorder and 20 healthy control participants with no lifetime history of psychiatric disorder underwent functional magnetic resonance imaging (fMRI) scanning during a card-guessing paradigm designed to examine reward-related brain function to anticipation and receipt of monetary reward and loss. Data were collected using a 3T Siemens Trio scanner. Results Region-of-interest analyses revealed that bipolar disorder participants displayed greater ventral striatal and right-sided orbitofrontal [Brodmann area (BA) 11] activity during anticipation, but not outcome, of monetary reward, relative to healthy controls (p < 0.05, corrected). Wholebrain analyses indicated that bipolar disorder, relative to healthy, participants also displayed elevated left-lateral OFC activity (BA 47) activity during reward anticipation (p < 0.05, corrected). Conclusions Elevated ventral striatal and OFC activity during reward anticipation may represent a neural mechanism for predisposition to expansive mood and hypo/mania in response to reward-relevant cues that characterizes bipolar disorder. Our findings contrast with research reporting blunted activity in the ventral striatum during reward processing in unipolar depressed individuals, relative to healthy controls. Examination of reward-related neural activity in bipolar disorder is a promising research focus to facilitate identification of biological markers of the illness. PMID:22548898

    DSM-5 changed the criteria from DSM-IV for mixed features in mood disorder episodes to include non-overlapping symptoms of depression and hypomania/mania. It is unknown if, by changing these criteria, the same group would qualify for mixed features. We assessed how those meeting DSM-5 criteria for mixed features compare to those meeting DSM-IV criteria. We analyzed data from 482 adult bipolar patients in Bipolar CHOICE, a randomized comparative effectiveness trial. Bipolar diagnoses were confirmed through the MINI International Neuropsychiatric Interview (MINI). Presence and severity of mood symptoms were collected with the Bipolar Inventory of Symptoms Scale (BISS) and linked to DSM-5 and DSM-IV mixed features criteria. Baseline demographics and clinical variables were compared between mood episode groups using ANOVA for continuous variables and chi-square tests for categorical variables. At baseline, the frequency of DSM-IV mixed episodes diagnoses obtained with the MINI was 17% and with the BISS was 20%. Using DSM-5 criteria, 9% of participants met criteria for hypomania/mania with mixed features and 12% met criteria for a depressive episode with mixed features. Symptom severity was also associated with increased mixed features with a high rate of mixed features in patients with mania/hypomania (63.8%) relative to those with depression (8.0%). Data on mixed features were collected at baseline only and thus do not reflect potential patterns in mixed features within this sample across the study duration. The DSM-5 narrower, non-overlapping definition of mixed episodes resulted in fewer patients who met mixed criteria compared to DSM-IV. Copyright © 2017. Published by Elsevier B.V.

    A 22-year-old male diagnosed with bipolar affective disorder presented to us with a 3(rd) episode mania resistant to both olanzapine and haloperidol as well as electroconvulsive therapy. He, however, responded to chlorpromazine (CPZ) which was also effective as a mood stabilizer. The patient had a relapse of his illness when CPZ was stopped and responded again when it was started. The case demonstrates that CPZ may have a role in as both an anti-manic agent and for the maintenance for bipolar disorders. The possible underlying mechanism for this role is also discussed.

    The pathophysiology of bipolar disorder, especially the underlying mechanisms of the bipolarity between manic and depressive states, has yet to be clarified. Microglia, immune cells in the brain, play important roles in the process of brain inflammation, and recent positron emission tomography studies have indicated microglial overactivation in the brain of patients with bipolar disorder. We have recently developed a technique to induced microglia-like (iMG) cells from peripheral blood (monocytes). We introduce a novel translational approach focusing on bipolar disorder using this iMG technique. We hypothesize that immunological conditional changes in microglia may contribute to the shift between manic and depressive states, and thus we herein analyzed gene profiling patterns of iMG cells from three patients with rapid cycling bipolar disorder during both manic and depressive states, respectively. We revealed that the gene profiling patterns are different between manic and depressive states. The profiling pattern of case 1 showed that M1 microglia is dominant in the manic state compared to the depressive state. However, the patterns of cases 2 and 3 were not consistent with the pattern of case 1. CD206, a mannose receptor known as a typical M2 marker, was significantly downregulated in the manic state among all three patients. This is the first report to indicate the importance of shifting microglial M1/M2 characteristics, especially the CD206 gene expression pattern between depressive and manic states. Further translational studies are needed to dig up the microglial roles in the underlying biological mechanisms of bipolar disorder. PMID:28119691

  2. Gene-Environment Interactions in Severe Mental Illness

    Full Text Available Severe mental illness is a broad category that includes schizophrenia, bipolar disorder and severe depression. Both genetic disposition and environmental exposures play important roles in the development of severe mental illness. Multiple lines of evidence suggest that the roles of genetic and environmental depend on each other. Gene-environment interactions may underlie the paradox of strong environmental factors for highly heritable disorders, the low estimates of shared environmental influences in twin studies of severe mental illness and the heritability gap between twin and molecular heritability estimates. Sons and daughters of parents with severe mental illness are more vulnerable to the effects of prenatal and postnatal environmental exposures, suggesting that the expression of genetic liability depends on environment. In the last decade, gene-environment interactions involving specific molecular variants in candidate genes have been identified. Replicated findings include an interaction between a polymorphism in the AKT1 gene and cannabis use in the development of psychosis and an interaction between the length polymorphism of the serotonin transporter gene and childhood maltreatment in the development of persistent depressive disorder. Bipolar disorder has been underinvestigated, with only a single study showing an interaction between a functional polymorphism in BDNF and stressful life events triggering bipolar depressive episodes. The first systematic search for gene-environment interactions has found that a polymorphism in CTNNA3 may sensitise the developing brain to the pathogenic effect of cytomegalovirus in utero, leading to schizophrenia in adulthood. Strategies for genome-wide investigations will likely include coordination between epidemiological and genetic research efforts, systematic assessment of multiple environmental factors in large samples, and prioritization of genetic variants.

    2011-07-01

    We examined a longstanding assumption in vocational psychology that people-things and data-ideas are bipolar dimensions. Two minimal criteria for bipolarity were proposed and examined across 3 studies: (a) The correlation between opposite interest types should be negative; (b) after correcting for systematic responding, the correlation should be greater than -.40. In Study 1, a meta-analysis using 26 interest inventories with a sample size of 1,008,253 participants showed that meta-analytic correlations between opposite RIASEC (realistic, investigative, artistic, social, enterprising, conventional) types ranged from -.03 to .18 (corrected meta-analytic correlations ranged from -.23 to -.06). In Study 2, structural equation models (SEMs) were fit to the Interest Finder (IF; Wall, Wise, & Baker, 1996) and the Interest Profiler (IP; Rounds, Smith, Hubert, Lewis, & Rivkin, 1999) with sample sizes of 13,939 and 1,061, respectively. The correlations of opposite RIASEC types were positive, ranging from .17 to .53. No corrected correlation met the criterion of -.40 except for investigative-enterprising (r = -.67). Nevertheless, a direct estimate of the correlation between data-ideas end poles using targeted factor rotation did not reveal bipolarity. Furthermore, bipolar SEMs fit substantially worse than a multiple-factor representation of vocational interests. In Study 3, a two-way clustering solution on IF and IP respondents and items revealed a substantial number of individuals with interests in both people and things. We discuss key theoretical, methodological, and practical implications such as the structure of vocational interests, interpretation and scoring of interest measures for career counseling, and expert RIASEC ratings of occupations.

    Objective: Although lithium has been a commonly prescribed neurotrophic/neuroprotective mood-stabilizing agents, its effect on spontaneous brain activity in patients with bipolar depression remains un-clear. The aim of this study is to reveal the basic mech-anism underlying the pathological influences of lithium on resting-state brain function of bipolar depression pa-tients. Methods:97 subjects including 9 bipolar depres-sion patients with lithium treatment, 19 bipolar depres-sion patients without lithium treatment and 69 healthy controls, were recruited to participate in this study. Amplitude of low-frequency fluctuation ( ALFF ) and fractional amplitude of low-frequency fluctuation ( fALFF) were used to capture the changes of spontane-ous brain activity among different groups. In addition, further analysis in terms of Hamilton Depression Rating Scale, the number of depressive episodes, and illness duration in pooled bipolar depression patients were con-ducted, which combined FLEF and fALEF to identify the basic neural features of bipolar depression patients. Results: It was observed from the imaging results that both the bipolar depression patients receiving lithium treatment and healthy control subjects showed signifi-cantly decreased ALFF/fALFF values in the right anteri-or cingulate cortex and right middle frontal gyrus com-pared to that from the bipolar depression patients with-out lithium treatmetn. The ALFF values of the right middle temporal gyrus was also found to be negative re-lated to the number of depressive episode and the total episodes. Conclusions:Our findings suggested that the bipolar depression subjects were identified to have ab-normal ALFF/ fALFF in the cortico-limbic systems, in-cluding regions like right anterior cingulate cortex, bi-lateral middle frontal gyrus, right orbital frontal gyrus, and right middle temporal gyrus. In addition, it was al-so revealed that the decreased ALFF/fALFF in the right anterior cingulate cortex and right

    Cortical and subcortical hyperintensities in magnetic resonance imaging (MRI) scans are thought to represent areas of ischemic damage to brain tissue. Researchers have focused on the possible role these lesions may have in psychiatric disorders, including bipolar disorder. In 1997, the proposed 'vascular mania' diagnosis suggested utilizing not only the presence of strokes, but also confluent hyperintensities in its diagnostic criteria. This study was conducted to use meta-analytic techniques to investigate the association of hyperintensities and bipolar illness and to evaluate the current state of the literature. Using the PubMed and MEDLINE databases, we conducted a systematic literature search of studies investigating hyperintensities in subjects with bipolar disorder and controls or other psychiatric illnesses. We identified 44 publications from which 35 studies were included for review and 27 were selected for meta-analysis. Summary statistics of the prevalence were estimated through odds-ratios and confidence interval. Heterogeneity of the results across studies was tested using Q-statistics. Meta-analysis identified an odds ratio of 2.5 (95% CI 1.9, 3.3) for hyperintensities in bipolar subjects compared to controls; however, there was significant heterogeneity among the studies (Q-statistics = 32; p = 0.04). This finding was most prominent for adolescents and children where the odds ratio was 5.7 (95% CI 2.3, 13.7). Deep white matter hyperintensities (odd ratio 3.2; 95% CI 2.2, 4.5) and subcortical grey matter hyperintensities (odds ratio 2.7; 95% CI 1.3, 2.9) were more strongly associated with bipolar subjects. There were no differences between bipolar subjects and controls for perivascular hyperintensities (odds ratio 1.3; 95% CI 0.8, 1.9). Though hyperintensities were numerically greater in bipolar subjects, meta-analysis did not demonstrate any significant differences between bipolar subjects and unipolar depression subjects (OR 1.6; 95% CI 0.9, 2.7) nor

    Full Text Available INTRODUCTION: Bipolar disorder (BD is a prevalent, chronic and progressive illness. There is a growing body of evidence indicating that brain-derived neurotrophic factor (BDNF plays an important role in the pathophysiology of BD. OBJECTIVE: The aim of this study was to evaluate BDNF plasma levels in BD patients with long term illness in comparison with controls. METHODS: 87 BD type I patients and 58 controls matched by age, gender and education level were enrolled in this study. All subjects were assessed by the Mini-International Neuropsychiatric Interview and the patients by the Young Mania Rating Scale and the Hamilton Depression Rating Scale. The plasma levels of BDNF were measured by ELISA. RESULTS: On average, patients had suffered from BD for 23.4 years. In comparison with controls, BD patients with mania presented a 1.90-fold increase in BDNF plasma levels (p = .001, while BD patients in remission presented a 1.64-fold increase in BDNF plasma levels (p = .03. BDNF plasma levels were not influenced by age, length of illness or current medications. CONCLUSIONS: The present study suggests that long-term BD patients exhibit increased circulating levels of BDNF.

    Full Text Available Abstract Background Nearly all information processing during cognitive processing takes place during periods of sustained attention. Sustained attention deficit is among the most commonly reported impairments in bipolar disorder (BP. The majority of previous studies have only focused on bipolar I disorder (BP I, owing to underdiagnosis or misdiagnosis of bipolar II disorder (BP II. With the refinement of the bipolar spectrum paradigm, the goal of this study was to compare the sustained attention of interepisode patients with BP I to those with BP II. Methods In all, 51 interepisode BP patients (22 with BP I and 29 with BP II and 20 healthy controls participated in this study. The severity of psychiatric symptoms was assessed by the 17-item Hamilton Depression Rating Scale and the Young Mania Rating Scale. All participants undertook Conners' Continuous Performance Test II (CPT-II to evaluate sustained attention. Results After controlling for the severity of symptoms, age and years of education, BP I patients had a significantly longer reaction times (F(2,68 = 7.648, P = 0.001, worse detectability (d' values (F(2,68 = 6.313, P = 0.003 and more commission errors (F(2,68 = 6.182, P = 0.004 than BP II patients and healthy controls. BP II patients and controls scored significantly higher than BP I patients for d' (F = 6.313, P = 0.003. No significant difference was found among the three groups in omission errors and no significant correlations were observed between CPT-II performance and clinical characteristics in the three groups. Conclusions These findings suggested that impairments in sustained attention might be more representative of BP I than BP II after controlling for the severity of symptoms, age, years of education and reaction time on the attentional test. A longitudinal follow-up study design with a larger sample size might be needed to provide more information on chronological sustained attention deficit in BP patients, and to illustrate

    Prospective study designs ideally allow patients to be followed from the first manifestations of the illness or even from an at-risk stage. It can thus provide data on the predictive value of changes in clinical symptomatology, cognition or further biological markers to broaden our understanding of the etiopathology and symptomatic trajectory of bipolar disorders. The scope of this narrative review is to summarize evidence from prospectively collected data on psychopathological and other clinical and biological changes in the early developmental course of bipolar disorders. The narrative review was based on a literature search conducted in February 2016 within the PubMed library for prospective study data of persons in antecedent and early manifest stages of manifest bipolar disorder published within the last 15 years. A total of 19 prospective studies were included. Regarding psychopathological features; personality, temperament and character traits as well as changes in sleep and circadian rhythm, the evidence suggests that risk factors for the development of bipolar disorder can already be described and should be studied further to understand their interaction, mediation with other factors and timing in the developmental process of bipolar disorder. Apart from the positive family history, childhood anxiety, sleep problems, subthreshold (hypo)manic symptoms and certain character traits/emotionality should be identified and monitored already in clinical practice as their presence likely increases risk of bipolar disorder. Up to date no substantiated evidence was found from prospective studies addressing cognitive features, life events, immunological parameters and morphological central nervous system changes as potential risk factors for bipolar disorder. For an improved understanding of episodic disorders, longitudinal data collection is essential. Since the etiology of bipolar disorders is complex, a number of potential risk factors have been proposed

    The use of lithium is a cornerstone for preventing recurrences in bipolar disorder (BD). The response of patients with bipolar disorder to lithium has different levels of magnitude. About one-third of lithium-treated patients are excellent lithium responders (ELR), showing total prevention of the episodes. A number of clinical characteristics were delineated in patients with favorable response to lithium as regards to clinical course, family history of mood disorders, and psychiatric comorbidity. We have also demonstrated that temperamental features of hypomania (a hyperthymic temperament) and a lack of cognitive disorganization predict the best results of lithium prophylaxis. A degree of prevention against manic and depressive episodes has been regarded as an endophenotype for pharmacogenetic studies. The majority of data have been gathered from so-called "candidate" gene studies. The candidates were selected on the basis of neurobiology of bipolar disorder and mechanisms of lithium action including, among others, neurotransmission, intracellular signaling, neuroprotection or circadian rhythms. We demonstrated that response to lithium has been connected with the genotype of BDNF gene and serum BDNF levels and have shown that ELR have normal cognitive functions and serum BDNF levels, even after long-term duration of the illness. A number of genome-wide association studies (GWAS) of BD have been also performed in recent years, some of which also focused on lithium response. The Consortium on Lithium Genetics (ConLiGen) has established the large sample for performing the genome-wide association study (GWAS) of lithium response in BD, and the first results have already been published.

  10. The miRNome of bipolar disorder.

    Fries, Gabriel R; Carvalho, Andre F; Quevedo, Joao

    2017-09-23

    Epigenetic mechanisms have been suggested to play a key role in the pathophysiology of bipolar disorder (BD), among which microRNAs (miRNAs) may be of particular significance according to recent studies. We aimed to summarize miRNA studies in BD to identify consistent findings, limitations, and future directions of this emerging field. We performed a comprehensive search on PUBMED and Medline for studies investigating an association between BD and miRNAs. The included studies report miRNA alterations in postmortem brain tissues and in the periphery, cell culture and preclinical findings, genetic associations, and the effects of medications. Several studies report changes in miRNA expression levels in postmortem brain and in the periphery of patients, although most of the results so far have not been replicated and are not concordant between different populations. Genetic studies also suggest that miRNA genes are located within susceptibility loci of BD, and also a putative role of miRNAs in modulating genes previously shown to confer risk of BD. We did not perform a systematic review of the literature, and miRNAs represent only one facet of the plethora of epigenetic mechanisms that might be involved in BD's pathophysiology. miRNA findings in BD significantly vary between studies, but are consistent to suggest a key role for these molecules in BD's pathophysiology and treatment, particularly miR-34a and miR-137. Accordingly, miRNA might represent important biomarkers of illness to be used in the clinical settings, and potentially also for the development of novel therapeutics for BD in the near future.

    Full Text Available Background/Aim. Bipolar affective disorder is mental disorder with polygenic type of heredity. Heritability - relation between genetic and environmental variance is used to estimate the level of influence of genetic variance to phenotype variance. Study results show decreasing trend in the value of heritability of bipolar affective disorder, thus indicating that this disorder is a complex behavioral threshold characteristic. Therefore, the aim of this study was to estimate the contribution of genetic variance to phenotype variance of bipolar affective disorder, i.e. to estimate heritability of this disorder. Methods. By the use of a questionnaire, 80 patients with over crossed threshold for bipolar affective disorder were asked for functional information about the members of their families belonging to the first degree of relation (fathers, mothers and full- sibs. By using ”Applet for calculating heritability for threshold traits (disease“, and regression analysis, heritability of bipolar affective disorder as well as its statistical significance, were estimated (χ2 test. Results. Heritability and relationship of genetic and environmental variance of bipolar affective disorder is 0.2 with statistically significant difference from zero (p < 0.001. Conclusion. The estimated contribution of genetic variance to phenotype variance of bipolar affective disorder is low being 20%, while the contribution of environmental variance is 80%. This result contributes to the understanding of bipolar affective disorder as a complex behavioral threshold trait.

    Nitric oxide (NO) is a neuromodulator involved in physiological and pathological processes in the retina. In the inner retina, a subgroup of amacrine cells have been shown to synthesize NO, but bipolar cells remain controversial as NO sources. This study correlates NO synthesis in dark-adapted retinas, through labeling with the NO marker DAF-FM, with neuronal nitric oxide synthase (nNOS) and inducible NOS expression, and presence of the NO receptor soluble guanylate cyclase in bipolar cells. NO containing bipolar cells were morphologically identified by dialysis of DAF fluorescent cells with intracellular dyes, or by DAF labeling followed by immunohistochemistry for nNOS and other cellular markers. DAF fluorescence was observed in all types of bipolar cells that could be identified, but the most intense DAF fluorescence was observed in bipolar cells with severed processes, supporting pathological NO signaling. Among nNOS expressing bipolar cells, type 9 was confirmed unequivocally, while types 2, 3a, 3b, 4, 5, 7, 8 and the rod bipolar cell were devoid of this enzyme. These results establish specific bipolar cell types as NO sources in the inner retina, and support the involvement of NO signaling in physiological and pathological processes in the inner retina.

    Aims: To study insight correlates in schizophrenia and bipolar mood disorder in remission among out-patients attending the Psychiatry Department of a Tertiary Care Hospital. Settings and Design: In a cross-sectional, naturalistic study, adult patients with schizophrenia and bipolar mood disorder in remission (n = 80; schizophrenia-40, mania-20, bipolar depression-20) were compared on insight measures and clinical correlates. Materials and Methods: Scale to Assess the Unawareness of Mental Disorders (SUMD) was used as the main tool to assess current and past measures of insight. Hogan's Drug Attitude Inventory was used to assess the drug attitude and compliance. Positive and Negative Symptom Scale for Schizophrenia, Young's Mania Rating Scale, and HAMD were used to rate psychopathology. Clinical Global Improvement was used as a screening tool for remission. Statistical Analysis: For comparison of the three clinical groups, analysis of variance and Chi-square test were used. In the post-hoc analysis, the Ryan-Einot-Gabriel-Welsch test was used to find the group difference. Results: About 40% in the schizophrenia group were unaware of their mental illness as against none in the bipolar group. The awareness of mental disorder for the current period, the awareness of the achieved effects of medications, and the awareness of social consequence was better in the bipolar group. The drug attitude (compliant positive attitude) increased as the SUMD item scale decreased or in other words, as the insight improved. Conclusions: Insight, both current and retrospect, showed significant differences between the schizophrenia and bipolar patients. Insight is significantly correlated with the observed compliance and drug attitude of the patient groups. PMID:27335515

    The greater severity and chronicity of illness in youths with co-occurring attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder deserve further investigation as to the risk imparted by comorbid conditions and the pharmacotherapies employed. A retrospective cohort design was employed, using South Carolina's Medicaid claims dataset covering outpatient and inpatient medical and psychiatric service claims with International Classification of Diseases, Ninth Revision, Clinical Modification diagnoses and medication prescriptions between January 1996 and December 2006 for patients ≤ 17 years of age. The cohort included 22,797 cases diagnosed with ADHD at a mean age of 7.8 years; 1,604 (7.0%) were diagnosed with bipolar disorder at a mean age of 12.2 years. The bipolar disorder group developed conduct disorder (CD)/oppositional defiant disorder (ODD), anxiety disorder, and a substance use disorder later than the ADHD-only group. The odds of a child with ADHD developing bipolar disorder were significantly and positively associated with a comorbid diagnosis of CD/ODD (adjusted odds ratio [aOR] = 4.01), anxiety disorder (aOR = 2.39), or substance use disorder (aOR = 1.88); longer treatment with methylphenidate, mixed amphetamine salts, or atomoxetine (aOR = 1.01); not being African American (aOR = 1.61); and being treated with certain antidepressant medications, most notably fluoxetine (aOR = 2.00), sertraline (aOR = 2.29), bupropion (aOR = 2.22), trazodone (aOR = 2.15), or venlafaxine (aOR = 2.37) prior to the first diagnosis of mania. Controlling for pharmacotherapy differences, incident bipolar disorder was more likely in individuals clustering specific patterns of comorbid psychiatric disorders, suggesting that there are different pathways to bipolarity and providing a clinical impetus for prioritizing prevention and preemptive strategies to reduce their hazardous influence. © Copyright 2014 Physicians Postgraduate Press, Inc.

    2009-09-30

    The purpose of the current investigation was to examine the personality predictors of bipolar disorder symptoms, conceptualized as one-dimensional (bipolarity) or two-dimensional (mania and depression). A psychiatric sample (N=370; 45% women; mean age 39.50 years) completed the Revised NEO Personality Inventory and the Minnesota Multiphasic Personality Inventory -2. A model in which bipolar symptoms were represented as a single dimension provided a good fit to the data. This dimension was predicted by Neuroticism and (negative) Agreeableness. A model in which bipolar symptoms were represented as two separate dimensions of mania and depression also provided a good fit to the data. Depression was associated with Neuroticism and (negative) Extraversion, whereas mania was associated with Neuroticism, Extraversion and (negative) Agreeableness. Symptoms of bipolar disorder can be usefully understood in terms of two dimensions of mania and depression, which have distinct personality correlates.

    The existence of bipolar disorder in adolescents is now clearly established. However, whether bipolarity exists in children is more controversial. We reviewed the literature on acute and prophylactic treatment of bipolar disorder in youths. The guidelines for the treatment of bipolar disorder in children and adolescents are generally similar to those applied in adult practice. But no evidence-based data support the use of mood stabilisers or antipsychotics since we only found two placebo-randomised controlled trials testing the efficacy of lithium in the paediatric literature. Therefore, we support the view that prescriptions should be limited to the most typical cases. In fact, the use of mood stabilisers or antipsychotics in the treatment of bipolar disorder in children and adolescents appears to be of limited use when a comorbid condition, such as attention deficit hyperactivity disorder, occurs unless aggressive behaviour is the target symptom.

    Bipolar disorder is a unique illness characterized by fluctuations between mood states of depression and mania. Originally, an adrenergic-cholinergic balance hypothesis was postulated to underlie these different affective states. In this review, we update this hypothesis with recent findings from human and animal studies, suggesting that a catecholaminergic-cholinergic hypothesis may be more relevant. Evidence from neuroimaging studies, neuropharmacological interventions, and genetic associations support the notion that increased cholinergic functioning underlies depression, whereas increased activations of the catecholamines (dopamine and norepinephrine) underlie mania. Elevated functional acetylcholine during depression may affect both muscarinic and nicotinic acetylcholine receptors in a compensatory fashion. Increased functional dopamine and norepinephrine during mania on the other hand may affect receptor expression and functioning of dopamine reuptake transporters. Despite increasing evidence supporting this hypothesis, a relationship between these two neurotransmitter systems that could explain cycling between states of depression and mania is missing. Future studies should focus on the influence of environmental stimuli and genetic susceptibilities that may affect the catecholaminergic-cholinergic balance underlying cycling between the affective states. Overall, observations from recent studies add important data to this revised balance theory of bipolar disorder, renewing interest in this field of research.

    Objective Psychopharmacology remains the foundation of treatment for bipolar disorder, but medication adherence in this population is low (Range = 20% to 64%). We examined medication adherence in a multi-site, comparative effectiveness study of lithium. Method The Lithium Moderate Dose Use Study (LiTMUS) was a six-month, six-site, randomized effectiveness trial of adjunctive moderate dose lithium therapy compared to optimized treatment in adult outpatients with bipolar I or II disorder (N=283). Medication adherence was measured at each study visit with the Tablet Routine Questionnaire. Results We found that 4.50% of participants reported missing at least 30% of their medications in the past week at baseline and non-adherence remained low throughout the trial (< 7%). Poor medication adherence was associated with more manic symptoms and side effects as well as lower lithium serum levels at mid- and post-treatment, but not with poor quality of life, overall severity of illness, or depressive symptoms. Conclusion Participants in LiTMUS were highly adherent with taking their medications. The lack of association with possible predictors of adherence, such as depression and quality of life, could be explained by the limited variance or other factors as well as by not using an objective measure of adherence.

    The silver-zinc (AgZn) battery system has been unique in its ability to safely satisfy high power demand applications with low mass and volume. However, a new generation of defense, aerospace, and commercial applications will impose even higher power demands. These new power demands can be satisfied by the development of a bipolar battery design. In this configuration the power consuming, interelectrode current conductors are eliminated while the current is then conducted via the large cross-section electrode substrate. Negative and positive active materials are applied to opposite sides of a solid silver foil substrate. In addition to reducing the weight and volume required for a specified power level, the output voltage performance is also improved as follows. Reduced weight through: elimination of the plastic cell container; elimination of plate leads and intercell connector; and elimination of internal plate current collector. Increased voltage through: elimination of resistance of current collector; elimination of resistance of plate lead; and elimination of resistance of intercell connector. EPI worked previously on development of a secondary bipolar silver zinc battery. This development demonstrated the electrical capability of the system and manufacturing techniques. One difficulty with this development was mechanical problems with the seals. However, recent improvements in plastics and adhesives should eliminate the major problem of maintaining a seal around the periphery of the bipolar module. The seal problem is not as significant for a primary battery application or for a requirement for only a few discharge cycles. A second difficulty encountered was with activation (introducing electrolyte into the cell) and with venting gas from the cell without loss of electrolyte. During previous work, the following projections for energy density were made from test data for a high power system which demonstrated in excess of 50 discharge/charge cycles. Projected

    Bipolar disorder is a mental disorder with chronic and remitting course. The disorder is related to high mortality and severely impairs everyday functioning. Therefore a scientifically sound and practical approach to treatment is needed. Making a long-term treatment plan usually also demands some creativity. The patient is interested in a number of issues, from the choice of therapy in acute phases to long-term treatment. Usual questions are how long shall I take the medications, do I really need all those pills or can we decrease the dosage of some drugs? This paper discussed the above mentioned questions in light of latest publications in this field.

    Objective This study examined general medical illnesses and their association with clinical features of bipolar disorder. Methods Data were cross-sectional and derived from the Lithium Treatment – Moderate Dose Use Study (LiTMUS), which randomized symptomatic adults (n=264 with available medical comorbidity scores) with bipolar disorder to moderate doses of lithium plus optimized treatment (OPT) or to OPT alone. Clinically significant high and low medical comorbidity burden were defined as a Cumulative Illness Rating Scale (CIRS) score ≥ 4 and < 4, respectively. Results The baseline prevalence of significant medical comorbidity was 53% (n=139). Patients with high medical burden were more likely to present in a major depressive episode (P=.04), meet criteria for obsessive-compulsive disorder (P=.02), and experience a greater number of lifetime mood episodes (P=0.02). They were also more likely to be prescribed a greater number of psychotropic medications (P=.002). Sixty-nine percent of the sample was overweight or obese as defined by body mass index (BMI), with African-Americans representing the racial group with the highest proportion of stage II obesity (BMI ≥ 35; 31%, n=14). Conclusions The burden of comorbid medical illnesses was high in this generalizable sample of treatment-seeking patients and appears associated with worsened course of illness and psychotropic medication patterns.

    Bipolar disorder, also known as manic depression, is a brain disorder that affects the brain structure of a patient. It results in extreme mood swings, severe states of depression, and overexcitement simultaneously. It is estimated that roughly 3% of the population of the United States (about 5.3 million adults) suffers from bipolar disorder. Recent research efforts like the Twin studies have demonstrated a high heritability factor for the disorder, making genomics a viable alternative for detecting and treating bipolar disorder, in addition to the conventional lengthy and costly postsymptom clinical diagnosis. Motivated by this study, leveraging several emerging deep learning algorithms, we design an end-to-end deep learning architecture (called DeepBipolar) to predict bipolar disorder based on limited genomic data. DeepBipolar adopts the Deep Convolutional Neural Network (DCNN) architecture that automatically extracts features from genotype information to predict the bipolar phenotype. We participated in the Critical Assessment of Genome Interpretation (CAGI) bipolar disorder challenge and DeepBipolar was considered the most successful by the independent assessor. In this work, we thoroughly evaluate the performance of DeepBipolar and analyze the type of signals we believe could have affected the classifier in distinguishing the case samples from the control set. © 2017 Wiley Periodicals, Inc.

    Bipolar disorder heterogeneity is large, leading to difficulties in identifying neuropathophysiological and etiological mechanisms and hindering the formation of clinically homogeneous patient groups in clinical trials. Identifying markers of clinically more homogeneous groups would help disentangle BD heterogeneity. Neuroimaging may aid in identifying such groups by highlighting specific biomarkers of BD subtypes or clinical dimensions. We performed a systematic literature search of the neuroimaging literature assessing biomarkers of relevant BD phenotypes (type-I vs. II, presence vs. absence of psychotic features, suicidal behavior and impulsivity, rapid cycling, good vs. poor medication response, age at onset, cognitive performance and circadian abnormalities). Consistent biomarkers were associated with suicidal behavior, i.e. frontal/anterior alterations (prefrontal and cingulate grey matter, prefrontal white matter) in patients with a history of suicide attempts; and with cognitive performance, i.e. involvement of frontal and temporal regions, superior and inferior longitudinal fasciculus, right thalamic radiation, and corpus callosum in executive dysfunctions. For the other dimensions and sub-types studied, no consistent biomarkers were identified. Studies were heterogeneous both in methodology and outcome. Though theoretically promising, neuroimaging has not yet proven capable of disentangling subtypes and dimensions of bipolar disorder, due to high between-study heterogeneity. We issue recommendations for future studies. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background There is increasing evidence for the effectiveness of structured psychological therapies for bipolar disorder. To date however there have been no psychological interventions specifically designed for individuals with early bipolar disorder. The primary objective of this trial is to establish the acceptability and feasibility of a new CBT based intervention (Recovery focused CBT; RfCBT designed in collaboration with individuals with early bipolar disorder intended to improve clinical and personal recovery outcomes. Methods and design This article describes a single blind randomised controlled trial to assess the feasibility and acceptability of RfCBT compared with treatment as usual. Participants will be recruited from across the North West of England from specialist mental health services and through primary care and self referral. The primary outcome of the study is the feasibility and acceptability of RfCBT as indicated by recruitment to target and retention to follow-up as well as absence of untoward incidents associated with RfCBT. We also intend to estimate the effect size of the impact of the intervention on recovery and mood outcomes and explore potential process measures (self appraisal, stigma, hope and self esteem. Discussion This is the first trial of recovery informed CBT for early bipolar disorder and will therefore be of interest to researchers in this area as well as indicating the wider potential for evaluating approaches to the recovery informed treatment of recent onset severe mental illness in general.

    2007-07-01

    Bipolar disorder is a complicated mental illness to diagnose and treat. The symptoms of the disorder cause a multitude of fluctuations in mood and behavior, affecting the way individuals function and interact with others on a daily basis. Individuals diagnosed with bipolar disorder experience symptoms within a framework that is grounded in their cultural beliefs, values, and norms. Culture is a complex and personal biopsychosocial phenomenon that provides meaning within life for an individual, a group, or a community. It is essential that psychiatric-mental health (PMH) nurses understand the role of culture and integrate this knowledge into the biopsychosocial care of clients. The development and maintenance of the interpersonal therapeutic relationship between PMH nurses and their clients requires the use of a cultural framework, which refers to the connection of culture and cultural competence. The purposes of this article are to define culture and the process of cultural competence, provide a brief overview of bipolar disorder, propose the use of a cultural framework for bipolar disorder, and discuss the implications for PMH nurses who care for culturally and ethnically diverse clients.

  16. Technology-Based Early Warning Systems for Bipolar Disorder: A Conceptual Framework.

    2016-09-07

    Recognition and timely action around "warning signs" of illness exacerbation is central to the self-management of bipolar disorder. Due to its heterogeneity and fluctuating course, passive and active mobile technologies have been increasingly evaluated as adjunctive or standalone tools to predict and prevent risk of worsening of course in bipolar disorder. As predictive analytics approaches to big data from mobile health (mHealth) applications and ancillary sensors advance, it is likely that early warning systems will increasingly become available to patients. Such systems could reduce the amount of time spent experiencing symptoms and diminish the immense disability experienced by people with bipolar disorder. However, in addition to the challenges in validating such systems, we argue that early warning systems may not be without harms. Probabilistic warnings may be delivered to individuals who may not be able to interpret the warning, have limited information about what behaviors to change, or are unprepared to or cannot feasibly act due to time or logistic constraints. We propose five essential elements for early warning systems and provide a conceptual framework for designing, incorporating stakeholder input, and validating early warning systems for bipolar disorder with a focus on pragmatic considerations.

    Internalized stigma of mental disorders has significant negative outcomes for patients with bipolar disorder and their families. The aim of this study is to evaluate the association between personality traits and internalized stigma of mental disorders in bipolar patients and their treatment partners. Five different questionnaires were utilized in this study: (1) Demographic data questionnaire, (2) Millon Clinical Multiaxial Inventory-III (MCMI-III) for personality traits, (3) Internalized Stigma of Mental Illness (ISMI) for stigma, (4) Self Report Manic Inventory (SRMI) for mania and (5) Center for Epidemiological Studies-Depression Scale (CES-D) for depression. The scores of personality traits were combined to create externalizing and internalizing personality trait scores. Results showed that patients with bipolar disorder and their treatment partners both experienced internalized stigma of mental health disorders. There was a significant positive correlation between internalized stigma and internalizing personality traits, but not externalizing traits. In a multi-variate regression analysis, internalizing personality trait score was found to be a significant predictor of internalized stigma. In conclusion, patients with bipolar disorder and their treatment partners perceive higher level of internalized stigma of mental disorders if they have internalizing personality traits.

    Few studies have examined pituitary gland size in mood disorders, particularly in adolescents. We hypothesized increase in the pituitary gland size in early-onset mood disorders. Thirty subjects between the ages of 13 and 20 years participated in the study. Three groups (control, bipolar I depression and unipolar depression) of 10 subjects each (4 male, 6 female) underwent volumetric magnetic resonance imaging at 1.5 T. Analysis of covariance (covarying for age, sex and intracranial volume) revealed a significant difference in pituitary gland volume amongst the groups [F(2,24) = 7.092, p = 0.014]. Post hoc analysis revealed that controls had a significantly smaller pituitary gland volume than both bipolar patients (p = 0.019) and depressed patients (p = 0.049). Bipolar and depressed subjects did not differ significantly from each other with regard to pituitary gland volume (p = 0.653). Control females had larger pituitary glands than control males [F(1,8) = 10.523, p = 0.012], but no sex differences were noted in the mood disorder groups. Pituitary glands are enlarged in adolescents with mood disorders compared to controls. Healthy young females have larger pituitary glands than males, but such a difference is not evident in individuals with unipolar depression or bipolar disorder. These findings provide new evidence of abnormalities of the pituitary in early onset mood disorders, and are consistent with neuroendocrine dysfunction in early stages of such illnesses.

    Bipolar disorder is a highly heritable mental illness. The global burden of bipolar disorder is complicated by its comorbidity with substance abuse. Several genome-wide linkage/association studies on bipolar disorder as well as substance abuse have focused on the identification and/or prioritization of candidate disease genes. A useful step for translational research of these identified/prioritized genes is to identify sets of genes that have particular kinds of publicly available data. Therefore, we have leveraged the availability of links to related resources in the Entrez Gene database to develop a web-based resource for selecting genes based on presence or absence in particular biological data resources. The utility of our approach is demonstrated using a set of 3,399 genes from multiple eukaryotes that have been studied in the context of bipolar disorder and/or substance abuse. A web resource to automate the selection of genes that contain certain database links is available at http://compbio.jsums.edu/bpd.

    To compare the physical fitness of inpatients with bipolar disorder, schizophrenia and healthy controls. Twenty-two inpatients with bipolar disorder, and 22 age-, gender- and body mass index-matched inpatients with schizophrenia and healthy controls were included. All participants performed the Eurofit test battery and the International Physical Activity Questionnaire. One way analyses of variance with post hoc Scheffe were applied to examine differences. Both patient groups were significantly more physically inactive and had a significantly impaired speed of limb movement, explosive muscle strength and abdominal muscular endurance compared to the healthy controls. No significant differences between the patient groups were found. The results suggest that physical fitness and physical activity participation are similar among inpatients with bipolar disorder and schizophrenia but markedly lower than healthy controls. Chronic inpatients with lower levels of physical activity may particularly benefit from rehabilitation interventions aimed at increasing physical fitness. Implications for Rehabilitation Physical fitness should receive similar attention in the treatment of bipolar disorder and schizophrenia. Sedentary patients with a longer duration of illness need additional support in changing lifestyle behaviours. Rehabilitation should not only consider cardio-respiratory fitness but also muscular endurance, muscular strength and balance.

    Single nucleotide allelic variants in the promoter region of the chromosome 15 alpha-7 acetylcholine nicotinic receptor gene (CHRNA7) are associated with both schizophrenia and the P50 auditory evoked potential sensory gating deficit. The purpose of this study was to determine if CHRNA7 promoter allelic variants are also associated with abnormal P50 ratios in persons with schizoaffective disorder, bipolar type. P50 auditory evoked potentials were recorded in a paired stimulus paradigm in 17 subjects with schizoaffective disorder, bipolar type. The P50 test to conditioning ratio was used as the measure of sensory gating. Mutation screening of the CHRNA7 promoter region was performed on the subjects' DNA samples. Comparisons to previously obtained data from persons with schizophrenia and controls were made. Subjects with schizophrenia, regardless of allele status, had an abnormal mean P50 ratio. Subjects with schizoaffective disorder, bipolar type and a variant allele had an abnormal mean P50 ratio, whereas those schizoaffective subjects with the common alleles had a normal mean P50 ratio. Normal control subjects had a normal mean ratio, but controls with variant alleles had higher P50 ratios. In persons with bipolar type schizoaffective disorder, CHRNA7 promoter region allelic variants are linked to the capacity to inhibit the P50 auditory evoked potential and thus are associated with a type of illness genetically and biologically more similar to schizophrenia.

    Introduction Bipolar spectrum disorder is a chronic, episodic illness, associated with significant personal, social and economic burden. It is estimated to affect ∼2.4% of the population worldwide and is commonly associated with psychological and/or physiological comorbidities. Osteoporosis is one such comorbidity, a disease of bone that is asymptomatic until a fracture occurs. This systematic review attempts to capture, collate, assess and discuss the literature investigating the association between bipolar spectrum disorder and bone health. Methods and analysis We aim to identify articles that investigate the association between bipolar spectrum disorder and bone health in adults by systematically searching the MEDLINE, PubMed, OVID and CINAHL databases. Two independent reviewers will determine eligibility of studies according to predetermined criteria, and methodological quality will be assessed using a previously published scoring system. A meta-analysis will be conducted, and statistical methods will be used to identify and control for heterogeneity, if possible. If numerical syntheses are prevented due to statistical heterogeneity, a best evidence synthesis will be conducted to assess the level of evidence for associations between bipolar spectrum disorder and bone health. Ethics and dissemination Ethical permission will not be required for this systematic review since only published data will be used. This protocol will be registered with PROSPERO. Findings of the review will be published in a peer-reviewed scientific journal, and will be presented to clinical and population health audiences at national and international conferences.

    Thyroid disfunction affects negatively emotional stability and worsens the clinical course of bipolar affective disorder. The main stabilizer used in this illness, lithium carbonate has numerous effects on the physiology of the thyroid, with the most significant being the inhibition of thyroid hormone release that may occur at therapeutic levels. These dysfunctions have also been reported most frequently in bipolar patients not undergoing treatment with lithium, and was not completely explained by the effects of this drug. Apart from the numerous medical complications and mood disturbances, the cognitive or perceptual system may also be affected. In fact, the presence of thyroid disease increases the rates of obsessive compulsive disorder, phobias, panic disorder, major depressive disorder, cyclothymia, or bipolar disorder. In severe cases of hypothyroidism, the clinical symptoms and signs can be similar to a melancholic depression or dementia. It is therefore important to know well all these possible complications in daily clinical practice. This review will cover the main thyroid dysfunctions present in bipolar patients, whether ot not produced by treatment with lithium carbonate, and will provide a series of recommendations for clinical management.

    Neurocognitive dysfunction in bipolar disorder represents a possible marker of underlying pathophysiology, but to date, most studies are cross-sectional and heterogeneous with regard to pharmacological treatments. In the present study we investigated the 6-year cognitive and functional outcome of a sample of euthymic excellent lithium responders (ELR). A total sample of twenty subjects was assessed at baseline and 6years later: ten diagnosed of bipolar disorder according to DSM-IV criteria and ten healthy matched controls. The sample size was enough to find statistical differences between groups, with a statistical power of 0.8. Bipolar patients were on lithium treatment during all this follow-up period and fulfilled ELR criteria as measured by the Alda scale. A neuropsychological test battery tapping into the main cognitive domains was used at baseline and at after 6-year of follow-up. Functional outcome was evaluated by means of the Functioning Assessment Short Test at study endpoint. Repeated measures multivariate analyses of variance showed that bipolar patients were cognitively impaired in the executive functioning, inhibition, processing speed and verbal memory domains (p<0.03) compared to controls and such deficits were stable over time. Longer duration of illness and lower psychosocial outcome were significantly related to cognitive impairment (p<0.05). Cognitive dysfunction was present even in euthymic ELR. These deficits remain stable over the long term, and are basically associated with greater symptoms and poorer psychosocial adjustment. Copyright © 2016 Elsevier Inc. All rights reserved.

  5. Technology-Based Early Warning Systems for Bipolar Disorder: A Conceptual Framework

    2016-01-01

    Recognition and timely action around “warning signs” of illness exacerbation is central to the self-management of bipolar disorder. Due to its heterogeneity and fluctuating course, passive and active mobile technologies have been increasingly evaluated as adjunctive or standalone tools to predict and prevent risk of worsening of course in bipolar disorder. As predictive analytics approaches to big data from mobile health (mHealth) applications and ancillary sensors advance, it is likely that early warning systems will increasingly become available to patients. Such systems could reduce the amount of time spent experiencing symptoms and diminish the immense disability experienced by people with bipolar disorder. However, in addition to the challenges in validating such systems, we argue that early warning systems may not be without harms. Probabilistic warnings may be delivered to individuals who may not be able to interpret the warning, have limited information about what behaviors to change, or are unprepared to or cannot feasibly act due to time or logistic constraints. We propose five essential elements for early warning systems and provide a conceptual framework for designing, incorporating stakeholder input, and validating early warning systems for bipolar disorder with a focus on pragmatic considerations.

    Full Text Available Bipolar disorder is a common, heritable mental illness characterized by recurrent episodes of mania and depression. Despite considerable effort to elucidate the genetic underpinnings of bipolar disorder, causative genetic risk factors remain elusive. We conducted a comprehensive genomic analysis of bipolar disorder in a large Old Order Amish pedigree. Microsatellite genotypes and high-density SNP-array genotypes of 388 family members were combined with whole genome sequence data for 50 of these subjects, comprising 18 parent-child trios. This study design permitted evaluation of candidate variants within the context of haplotype structure by resolving the phase in sequenced parent-child trios and by imputation of variants into multiple unsequenced siblings. Non-parametric and parametric linkage analysis of the entire pedigree as well as on smaller clusters of families identified several nominally significant linkage peaks, each of which included dozens of predicted deleterious variants. Close inspection of exonic and regulatory variants in genes under the linkage peaks using family-based association tests revealed additional credible candidate genes for functional studies and further replication in population-based cohorts. However, despite the in-depth genomic characterization of this unique, large and multigenerational pedigree from a genetic isolate, there was no convergence of evidence implicating a particular set of risk loci or common pathways. The striking haplotype and locus heterogeneity we observed has profound implications for the design of studies of bipolar and other related disorders.

    Full Text Available Abstract Background Manic-depression or bipolar disorder (BD is a multi-faceted illness with an inevitably complex treatment. Methods This article summarizes the current status of our knowledge and practice of its treatment. Results It is widely accepted that lithium is moderately useful during all phases of bipolar illness and it might possess a specific effectiveness on suicidal prevention. Both first and second generation antipsychotics are widely used and the FDA has approved olanzapine, risperidone, quetiapine, ziprasidone and aripiprazole for the treatment of acute mania. These could also be useful in the treatment of bipolar depression, but only limited data exists so far to support the use of quetiapine monotherapy or the olanzapine-fluoxetine combination. Some, but not all, anticonvulsants possess a broad spectrum of effectiveness, including mixed dysphoric and rapid-cycling forms. Lamotrigine may be effective in the treatment of depression but not mania. Antidepressant use is controversial. Guidelines suggest their cautious use in combination with an antimanic agent, because they are supposed to induce switching to mania or hypomania, mixed episodes and rapid cycling. Conclusion The first-line psychosocial intervention in BD is psychoeducation, followed by cognitive-behavioral therapy. Other treatment options include Electroconvulsive therapy and transcranial magnetic stimulation. There is a gap between the evidence base, which comes mostly from monotherapy trials, and clinical practice, where complex treatment regimens are the rule.

    Objective At least 50% of individuals with bipolar disorder have a lifetime anxiety disorder. Individuals with both bipolar disorder and a co-occurring anxiety disorder experience longer illness duration, greater illness severity, and poorer treatment response. The study explored whether comorbid lifetime anxiety in bipolar patients moderates psychotherapy treatment outcome. Method In the Systematic Treatment Enhancement Program randomized controlled trial of psychotherapy for bipolar depression, participants received up to 30 sessions of intensive psychotherapy (family-focused therapy, interpersonal and social rhythm therapy, or cognitive-behavioral therapy) or collaborative care, a three-session comparison treatment, plus pharmacotherapy. Using the number needed to treat, we computed effect sizes to analyze the relationship between lifetime anxiety disorders and rates of recovery across treatment groups after 1 year. Results A total of 269 patients (113 women) with a comorbid lifetime anxiety disorder (N=177) or without a comorbid lifetime anxiety disorder (N=92) were included in the analysis. Participants with a lifetime anxiety disorder were more likely to recover with psychotherapy than with collaborative care (66% compared with 49% recovered over 1 year; number needed to treat=5.88, small to medium effect). For patients without a lifetime anxiety disorder, there was no difference between rates of recovery in psychotherapy compared with collaborative care (64% compared with 62% recovered; number needed to treat=50, small effect). Participants with one lifetime anxiety disorder were likely to benefit from intensive psychotherapy compared with collaborative care (84% compared with 53% recovered; number needed to treat=3.22, medium to large effect), whereas patients with multiple anxiety disorders exhibited no difference in response to the two treatments (54% compared with 46% recovered; number needed to treat=12.5, small effect). Conclusions Depressed patients

    Impulsivity as a tendency to act quickly without considering future consequences has been proposed as a dimensional factor in bipolar disorder. It can be measured using behavioral tasks and self-report questionnaires. Previous findings revealed patients to show worse performance on at least one behavioral measure of impulsivity. Additionally, self-reported impulsivity seems to be higher among bipolar patients, both parameters being possibly associated with a more severe course of illness. In this study, our primary aim was to investigate the relationship between these two constructs of impulsivity among bipolar patients. A total of 40 euthymic patients with bipolar disorder (21 female, 22 Bipolar I) and 30 healthy controls were recruited for comprehensive neuropsychological assessment. To assess inhibition control as a behavioral measure of impulsivity, the Stroop Color and Word Test (Stroop) was used. Additionally, both groups completed the Barratt Impulsiveness Scale (BIS) as a self-report of impulsivity. To compare the groups' performance on the Stroop and ratings on the BIS, the non-parametric Mann-Whitney U test was used. Within the bipolar group, we additionally examined the possibility of an association between Stroop performance and BIS total scores using Pearson's Correlation r. Patients and controls differed significantly on the Stroop and BIS, with patients performing worse on the Stroop and scoring higher on the BIS. However, there was no association between the Stroop and BIS within the bipolar group. As an exploratory analysis, a positive correlation between Stroop performance and number of episodes was found. Further, we detected a statistical trend in the direction of poorer Stroop performance among patients treated with polypharmacy. Both difficulties with behavioral inhibition and self-reported impulsivity were observed to be higher in bipolar patients than controls in the current study. However, within the patient group we did not observe an

    Because affective pathogenesis is a hard problem for psychiatry, it behoves researchers to develop and test novel models of causality. We examine the notion that the adaptive drive to social investment - prestige - provides clues to the bipolar spectrum. A seven node bipolar spectrum is proposed, based on a putative gradient of "bipolarity". It is conceived that this gradient may correlate with the drive to social investment (prestige). In order to test this hypothesis with proof of concept data, a case control study categorised 228 subjects into a seven node bipolar spectrum. Whilst controlling for mood elevation and depression, differences in strategic prestige (leadership) motivation (MSPM) between spectrum groups were examined. The bipolar I (S1) node had a greater strategic prestige (leadership) motivation score than the controls (S7) by 21.17 points, 95% CI [8.16, 34.18], pbipolar II (S2) node was higher than the control group by 16.73 points, 95% CI [0.92, 32.54], p=.030, d=0.84. Whilst the pseudounipolar (S3) node (those with depression and bipolar family histories; n=17) had only a marginally statistical difference in MSPM compared to controls (p=.051), the mean difference (16.98) and d value (0.86) indicated an elevated MSPM level. Prestige (leadership) motivation score positively correlated with dimensional lifetime bipolarity (Mood Disorder Questionnaire) score (rp=0.47), supporting the spectrum prestige motivation gradient notion. Evidence is presented for a genetic disposition to elevated strategic prestige (leadership) motivation. Sensitivity to Social Inclusion (MSIS), Contingency of Self-Worth (CSW.av) and tension significantly predicted strategic prestige (leadership) motivation (MSPM) score in a multiple regression. - suggesting that a vulnerability of the social self may be a feature of bipolar disorders. The prestige model of spectrum bipolarity offers a new conceptualisation of affective disorders and has received preliminary support.

    Despite burgeoning literature in middle-aged adults, little is known regarding proinflammatory markers (PIMs) among adolescents and young adults with bipolar disorder. Similarly, few prior studies have considered potential confounds when examining the association between PIMs and bipolar disorder characteristics. We therefore retrospectively examined these topics in the Course and Outcome of Bipolar Youth (COBY) study. Subjects were 123 adolescents and young adults (mean [SD] = 20.4 ± 3.8 years; range, 13.4-28.3 years) in COBY, enrolled between October 2000 and July 2006. DSM-IV diagnoses were determined using the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS). Clinical characteristics during the preceding 6 months, including mood, comorbidity, and treatment, were evaluated using the Longitudinal Interval Follow-Up Evaluation (LIFE). Serum levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, and high-sensitivity C-reactive protein (hsCRP) were assayed. Primary analyses examined the association of PIMs with bipolar disorder characteristics during the preceding 6 months. Several lifetime clinical characteristics were significantly associated with PIMs in multivariable analyses, including longer illness duration (P = .005 for IL-6; P = .0004 for hsCRP), suicide attempts (P = .01 for TNF-α), family history of suicide attempts or completion (P = .01 for hsCRP), self-injurious behavior (P =.005 for TNF-α), substance use disorder (SUD) (P bipolar disorder characteristics during the preceding 6 months remained significantly associated with PIMs in multivariable analyses that controlled for differences in comorbidity and treatment: for TNF-α, percentage of weeks with psychosis (χ(2) = 5.7, P =.02); for IL-6, percentage of weeks with subthreshold mood symptoms (χ(2)= 8.3, P = .004) and any suicide attempt (χ(2) = 6.1, P = .01); for hsCRP, maximum severity of depressive symptoms (χ(2) = 8.3, P =.004).

    Bipolar disorder is a severe and chronic disorder, ranked in the top 10 leading causes of disability worldwide. Sleep disturbances are strongly coupled with interepisode dysfunction and symptom worsening in bipolar disorder. Experimental studies suggest that sleep deprivation can trigger manic relapse. There is evidence that sleep deprivation can have an adverse impact on emotion regulation the following day. The clinical management of the sleep disturbances experienced by bipolar patients, including insomnia, hypersomnia delayed sleep phase, and irregular sleep-wake schedule, may include medication approaches, psychological interventions, light therapies and sleep deprivation.

In particular, it is the semantic relationship between the opposite categories...... and at the same time the type of neutrality rising in between opposites. Based on this first level of bipolar knowledge representation, paired structures in fact offer the means to characterize a specific bipolar valuation scale depending on the meaning of the concept that has to be verified.

    Little longitudinal research has examined progression to more severe bipolar disorders in individuals with “soft” bipolar spectrum conditions. We examine rates and predictors of progression to bipolar I and II diagnoses in a non-patient sample of college-age participants (n = 201) with high General Behavior Inventory scores and childhood or adolescent onset of “soft” bipolar spectrum disorders followed longitudinally for 4.5 years from the Longitudinal Investigation of Bipolar Spectrum (LIBS) project. Of 57 individuals with initial cyclothymia or bipolar disorder not otherwise specified (BiNOS) diagnoses, 42.1% progressed to a bipolar II diagnosis and 10.5% progressed to a bipolar I diagnosis. Of 144 individuals with initial bipolar II diagnoses, 17.4% progressed to a bipolar I diagnosis. Consistent with hypotheses derived from the clinical literature and the Behavioral Approach System (BAS) model of bipolar disorder, and controlling for relevant variables (length of follow-up, initial depressive and hypomanic symptoms, treatment-seeking, and family history), high BAS sensitivity (especially BAS Fun Seeking) predicted a greater likelihood of progression to bipolar II disorder, whereas early age of onset and high impulsivity predicted a greater likelihood of progression to bipolar I (high BAS sensitivity and Fun-Seeking also predicted progression to bipolar I when family history was not controlled). The interaction of high BAS and high Behavioral Inhibition System (BIS) sensitivities also predicted greater likelihood of progression to bipolar I. We discuss implications of the findings for the bipolar spectrum concept, the BAS model of bipolar disorder, and early intervention efforts. PMID:21668080

    Recent studies have reported lifetime prevalence estimates of 1.0% for bipolar I disorder, 1.1% for bipolar II disorder, and 2.4% to 4.7% for subthreshold bipolar disorder, illustrating the need for consensus definitions of bipolar spectrum disorders. These definitions will aid researchers in studying viable treatments options, as well as help clinicians in the differential diagnosis of patients. Broader definitions of bipolar spectrum disorders would also allow clinicians to more accurately diagnose patients, rather than placing them in the catchall category of bipolar disorder not otherwise specified. Bipolar symptoms that are currently labeled as subthreshold symptoms are becoming increasingly recognized as having relevant clinical implications. Despite diagnostic controversy, screening for the presence of mania in patients who present with depressive symptoms is a critical step in the appropriate treatment of bipolar spectrum disorders. Identifying the early onset of bipolar symptoms as manifested in prodromal disorders such as childhood major depressive disorder and attention-deficit/hyperactivity disorder is also important for possible early intervention and improved outcomes.

    There are some arguments that Friedrich Nietzsche suffered from the autosomal dominant vascular microangiopathy: Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL). Here, a hypothesis is formulated supporting that CADASIL presenting with symptoms of bipolar disorder and Gastaut-Geschwind syndrome would contribute to the increased insight and creativity of a philosopher whose perceptions and intuitions often bear out the results of modern neuroscience. Alterations of the brain default and reward networks would account for such an increased level of introspection and creativity. A new framework on approaching illness is proposed, which, in conformity with Nietzsche's positive view, outlines the enabling aspects of some otherwise highly disabling neuropsychiatric disorders.

    For physicians with psychiatric illness, especially when newly diagnosed, one concern can be what effect patients' knowledge of their physician's diagnosis can have on their relationship. As a pediatrician with bipolar disease, about which many patients and the community are well aware, I've found that patients are much more concerned with the quality of care they receive than with whatever psychiatric problems their physician might have. I offer this narrative in hopes that it will allay other physicians' fears of "disclosure." © 2016 American Medical Association. All Rights Reserved. ISSN 2376-6980.

    Psychiatric patients with bipolar disorder suffer from states of depression and mania, during which a variety of symptoms are present. Current treatments are limited and neurocognitive deficits in particular often remain untreated. Targeted therapies based on the biological mechanisms of bipolar disorder could fill this gap and benefit patients and their families. Developing targeted therapies would benefit from appropriate animal models which are challenging to establish, but remain a vital tool. In this review, we summarize approaches to create a valid model relevant to bipolar disorder. We focus on studies that use translational tests of multivariate exploratory behavior, sensorimotor gating, decision-making under risk, and attentional functioning to discover profiles that are consistent between patients and rodent models. Using this battery of translational tests, similar behavior profiles in bipolar mania patients and mice with reduced dopamine transporter activity have been identified. Future investigations should combine other animal models that are biologically relevant to the neuropsychiatric disorder with translational behavioral assessment as outlined here. This methodology can be utilized to develop novel targeted therapies that relieve symptoms for more patients without common side effects caused by current treatments. PMID:26297513

    Full Text Available Depression, Major Depression or mental disorder creates severe diseases. Mental illness such as Unipolar Major Depression, Bipolar Disorder, Dysthymia, Schizophrenia, Cardiovascular Diseases (Hypertension, Coronary Heart Disease, Stroke etc., are known as Major Depression. Several studies have revealed the possibilities about the association among Bipolar Disorder, Schizophrenia, Coronary Heart Diseases and Stroke with each other. The current study aimed to investigate the relationships between genetic variants in the above four diseases and to create a common pathway or PPI network. The associated genes of each disease are collected from different gene database with verification using R. After performing some preprocessing, mining and operations using R on collected genes, seven (7 common associated genes are discovered on selected four diseases (SZ, BD, CHD and Stroke. In each of the iteration, the numbers of collected genes are reduced up to 51%, 36%, 10%, 2% and finally less than 1% respectively. Moreover, common pathway on selected diseases has been investigated in this research.

    We developed an integrated psychosocial treatment for bipolar disorder to decrease the disproportionate medical burden associated with this illness. Three treatment modules, Nutrition/weight loss, Exercise, and Wellness Treatment (NEW Tx) were administered in twelve 60-minute group sessions over 14 weeks. After the first group (N=4) had completed the treatment, it was revised, and then a second group (N=6) completed the revised treatment. Participants completed all of the study assessments and attended 82% of the sessions. Both groups added over 100 minutes of weekly exercise to their baseline duration. Participants in the second group showed improvements in their quality of life, depressive symptoms, and weight. It appears that NEW Tx may be a feasible intervention with promising pilot data for reducing the medical burden in bipolar disorder, but future research is needed to further evaluate the efficacy of NEW Tx.

    The cyclical nature of periodic switches in energy, motor activation and sleep-wake cycles in bipolar disorder suggests a strong underlying relationship with disturbances in chronobiology. Current research is refining our understanding of the various patterns of sleep-wake and biological rhythms alterations at early and later stages of this illness, as well as across its depressive/fatigue, manic/hypomanic and euthymic phases. This research focuses on early detection and subsequent monitoring to predict and better manage recurrent episodes. Sleep-wake cycle and biological rhythms disturbances are also well known to affect other key aspects of physical health (notably metabolic functions), cognitive performance and elevated risks for suicide. Increasing evidence now supports the integration of behavioural or pharmacological therapeutic strategies that target the sleep-wake and circadian systems in the ongoing treatment of various phases of bipolar disorder.

Traditional mood stabilizers such as lithium, valproate, and carbamazepine are often inadequate in controlling symptoms both during the acute and maintenance phase of treatment. Aripiprazole is a second-generation antipsychotic with a unique mechanism of action. Evidence suggests that it is effective in acute manic and mixed states. There are limited data to suggest its efficacy as a maintenance agent. Future studies will be needed to better define the role of aripiprazole relative to other traditional pharmacologic agents.Keywords: aripiprazole, bipolar disorder, acute treatment, maintenance treatment

    Schizophrenia and bipolar disorder are leading causes of morbidity across all populations, with heritability estimates of approximately 80% indicating a substantial genetic component. Population genetics and genome-wide association studies suggest an overlap of genetic risk factors between these illnesses but it is unclear how this genetic component is divided between common gene polymorphisms, rare genomic copy number variants, and rare gene sequence mutations. We report evidence that the lipid transporter gene ABCA13 is a susceptibility factor for both schizophrenia and bipolar disorder. After the initial discovery of its disruption by a chromosome abnormality in a person with schizophrenia, we resequenced ABCA13 exons in 100 cases with schizophrenia and 100 controls. Multiple rare coding variants were identified including one nonsense and nine missense mutations and compound heterozygosity/homozygosity in six cases. Variants were genotyped in additional schizophrenia, bipolar, depression (n > 1600), and control (n > 950) cohorts and the frequency of all rare variants combined was greater than controls in schizophrenia (OR = 1.93, p = 0.0057) and bipolar disorder (OR = 2.71, p = 0.00007). The population attributable risk of these mutations was 2.2% for schizophrenia and 4.0% for bipolar disorder. In a study of 21 families of mutation carriers, we genotyped affected and unaffected relatives and found significant linkage (LOD = 4.3) of rare variants with a phenotype including schizophrenia, bipolar disorder, and major depression. These data identify a candidate gene, highlight the genetic overlap between schizophrenia, bipolar disorder, and depression, and suggest that rare coding variants may contribute significantly to risk of these disorders.

    l-type calcium channel (LTCC) antagonists have been used in bipolar disorder for over 30 years, without becoming an established therapeutic approach. Interest in this class of drugs has been rekindled by the discovery that LTCC genes are part of the genetic aetiology of bipolar disorder and related phenotypes. We have therefore conducted a systematic review of LTCC antagonists in the treatment and prophylaxis of bipolar disorder. We identified 23 eligible studies, with six randomised, double-blind, controlled clinical trials, all of which investigated verapamil in acute mania, and finding no evidence that it is effective. Data for other LTCC antagonists (diltiazem, nimodipine, nifedipine, methyoxyverapamil and isradipine) and for other phases of the illness are limited to observational studies, and therefore no robust conclusions can be drawn. Given the increasingly strong evidence for calcium signalling dysfunction in bipolar disorder, the therapeutic candidacy of this class of drugs has become stronger, and hence we also discuss issues relevant to their future development and evaluation. In particular, we consider how genetic, molecular and pharmacological data can be used to improve the selectivity, efficacy and tolerability of LTCC antagonists. We suggest that a renewed focus on LTCCs as targets, and the development of ‘brain-selective' LTCC ligands, could be one fruitful approach to innovative pharmacotherapy for bipolar disorder and related phenotypes.

    There is considerable evidence that white matter abnormalities play a key role in the pathogenesis of a number of major psychiatric disorders, including schizophrenia, bipolar affective disorder, and obsessive-compulsive disorder. Few studies, however, have compared white matter abnormalities early in the course of the illness. A total of 102 children and adolescents participated in the study, including 43 with early-onset schizophrenia, 13 with early-onset bipolar affective disorder, 17 with obsessive-compulsive disorder, and 29 healthy controls. Diffusion tensor imaging scans were obtained on all children and the images were assessed for the presence of non-spatially overlapping regions of white matter differences, a novel algorithm known as the pothole approach. Patients with early-onset schizophrenia and early-onset bipolar affective disorder had a significantly greater number of white matter potholes compared to controls, but the total number of potholes did not differ between the two groups. The volumes of the potholes were significantly larger in patients with early-onset bipolar affective disorder compared to the early-onset schizophrenia group. Children and adolescents with obsessive-compulsive disorder showed no differences in the total number of white matter potholes compared to controls. White matter abnormalities in early-onset schizophrenia and bipolar affective disorder are more global in nature, whereas children and adolescents with obsessive-compulsive disorder do not show widespread differences in FA.

    To describe the incidence, major risk factors, and the clinical, electrophysiological, and histological features of critical illness myopathy (CIM). Major pathogenetic mechanisms and long-term consequences of CIM are also reviewed. CIM is frequently associated with critical illness polyneuropathy (CIP), and may have a relevant impact on patients' outcome. CIM has an earlier onset than CIP, and recovery is faster. Loss of myosin filaments on muscle biopsy is important to diagnose CIM, and has a good prognosis. Critical illness, use of steroids, and immobility concur in causing CIM. A rationale diagnostic approach to CIM using clinical, electrophysiological, and muscle biopsy investigations is important to plan adequate therapy and to predict recovery.

A “ventral semantic stream” has been discovered connecting the TP and OFC through the uncinate and inferior longitudinal fasciculi and the elusive TP is known to be involved in theory of mind and complex narrative understanding tasks. The OFC is involved in abstract valuation in goal and sub-goal structures and the TP may be critical in binding semantic memory with person–emotion linkages associated with narrative. BD patients have relative attenuation of performance on visuoconstructional praxis consistent with an atypical localization of cognitive functions. Multiple lines of evidence suggest that some BD alleles are being selected for which could explain the enhanced creativity in higher-ability probands.

  20. Miniature Bipolar Electrostatic Ion Thruster

    The figure presents a concept of a bipolar miniature electrostatic ion thruster for maneuvering a small spacecraft. The ionization device in the proposed thruster would be a 0.1-micron-thick dielectric membrane with metal electrodes on both sides. Small conical holes would be micromachined through the membrane and electrodes. An electric potential of the order of a volt applied between the membrane electrodes would give rise to an electric field of the order of several mega-volts per meter in the submicron gap between the electrodes. An electric field of this magnitude would be sufficient to ionize all the molecules that enter the holes. In a thruster-based on this concept, one or more propellant gases would be introduced into such a membrane ionizer. Unlike in larger prior ion thrusters, all of the propellant molecules would be ionized. This thruster would be capable of bipolar operation. There would be two accelerator grids - one located forward and one located aft of the membrane ionizer. In one mode of operation, which one could denote the forward mode, positive ions leaving the ionizer on the backside would be accelerated to high momentum by an electric field between the ionizer and an accelerator grid. Electrons leaving the ionizer on the front side would be ejected into free space by a smaller accelerating field. The equality of the ion and electron currents would eliminate the need for an additional electron- or ion-emitting device to keep the spacecraft charge-neutral. In another mode of operation, which could denote the reverse mode, the polarities of the voltages applied to the accelerator grids and to the electrodes of the membrane ionizer would be the reverse of those of the forward mode. The reversal of electric fields would cause the ion and electrons to be ejected in the reverse of their forward mode directions, thereby giving rise to thrust in the direction opposite that of the forward mode.

    The family caregivers of people with mental illness may internalize the public stereotypes into the affiliate stigma (i.e., the self-stigma of family members). This study aimed to compare the affiliate stigma across schizophrenia, bipolar disorder, and major depressive disorder, and to investigate potential factors associated with affiliate stigma. Each caregiver of family members with schizophrenia (n = 215), bipolar disorder (n = 85), and major depressive disorder (n = 159) completed the Affiliate Stigma Scale, Rosenberg Self-Esteem Scale, Caregiver Burden Inventory, Taiwanese Depression Questionnaire, and Beck Anxiety Inventory. After controlling for potential confounders, the hierarchical regression models showed that caregivers of a family member with schizophrenia had a higher level of affiliate stigma than those of bipolar disorder (β = -0.109; p stigma. The affiliate stigma of caregivers is associated with their self-esteem, caregiver burden, and by the diagnosis.

    In bipolar disorder, the factors provoking a new episode are unknown. As a seasonal variation has been noticed, it has been suggested that weather conditions may play a role. The aim of the study was to elucidate whether meteorological parameters influence the development of new bipolar phases....... A group of patients with at least three previous hospitalizations for bipolar disorder was examined every 3 months for up to 3 years. At each examination an evaluation of the affective phase was made according to the Hamilton Depression Scale (HAM-D(17)), and the Bech-Rafaelsen Mania Rating Scale (MAS......). In the same period, daily recordings from the Danish Meteorological Institute were received. We found no correlations between onset of bipolar episodes [defined as MAS score of 11 or more (mania) and as HAM-D(17) score of 12 or more (depression)] and any meteorological parameters.

    Schizophrenia and bipolar disorder share a number of common features, both symptomatically and biologically. Abnormalities in the neuroimmune and the stress-signaling pathways have been previously identified in brains of individuals with both diseases. However, the possible relationship between abnormalities in stress and neuroimmune signaling within the cortex of people with psychotic illness has not been defined. To test the hypothesis that combined alterations in brain stress responsiveness and neuroimmune/inflammatory status are characteristic of some individuals suffering from major mental illness, we examined gene expression in the Stanley Array Cohort of 35 controls, 35 individuals with schizophrenia and 34 individuals with bipolar disorder. We used levels of 8 inflammatory-related transcripts, of which SERPINA3 was significantly elevated in individuals with schizophrenia (F(2,88)=4.137, Pinflammation/stress group (n=32) and a low (n=68) inflammation/stress group. The high inflammation/stress group has a significantly greater number of individuals with schizophrenia (n=15), and a trend toward having more bipolar disorder individuals (n=11), when compared with controls (n=6). Using these subgroups, we tested which microarray-assessed transcriptional changes may be associated with high inflammatory/stress groups using ingenuity analysis and found that an extended network of gene expression changes involving immune, growth factors, inhibitory signaling and cell death factors also distinguished these groups. Our work demonstrates that some of the heterogeneity in schizophrenia and bipolar disorder may be partially explained by inflammation/stress interactions, and that this biological subtype cuts across Diagnostic and Statistical Manual of Mental Disorders (DSM)-defined categories.

    Few long-term studies on bipolar disorder (BD) have investigated the incidence and risk factors of suicide attempts (SAs) specifically related to illness phases. We examined the incidence of SAs during different phases of BD in a long-term prospective cohort of bipolar I (BD-I) and bipolar II (BD-II) patients, and risk factors specifically for SAs during major depressive episodes (MDEs). In the Jorvi Bipolar Study (JoBS), 191 BD-I and BD-II patients were followed using life-chart methodology. Prospective information on SAs of 177 patients (92.7%) during different illness phases was available up to 5 years. The incidence of SAs and their predictors were investigated using logistic and Poisson regression models. Analyses of risk factors for SAs occurring during MDEs were conducted using two-level random-intercept logistic regression models. During the 5 years of follow-up, 90 SAs per 718 patient-years occurred. The incidence was highest, over 120-fold higher than in euthymia, during mixed states (765/1000 person-years; 95% confidence interval [CI] 461-1269 person-years), and also very high in MDEs, almost 60-fold higher than in euthymia (354/1000 person-years; 95% CI 277-451 person-years). For risk of SAs during MDEs, the duration of MDEs, severity of depression, and cluster C personality disorders were significant predictors. We confirmed in this long-term study that the highest incidences of SAs occur in mixed and major depressive illness phases. The variations in incidence rates between euthymia and illness phases were remarkably large, suggesting that the question "when" rather than "who" may be more relevant for suicide risk in BD. However, risk during MDEs is likely also influenced by personality factors. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Bipolar disorders (BDs) and addictions constitute reciprocal risk factors and are best considered under a unitary perspective. The concepts of allostasis and allostatic load (AL) may contribute to the understanding of the complex relationships between BD and addictive behaviors. Allostasis entails the safeguarding of reward function stability by recruitment of changes in the reward and stress system neurocircuitry and it may help to elucidate neurobiological underpinnings of vulnerability to addiction in BD patients. Conceptualizing BD as an illness involving the cumulative build-up of allostatic states, we hypothesize a progressive dysregulation of reward circuits clinically expressed as negative affective states (i.e., anhedonia). Such negative affective states may render BD patients more vulnerable to drug addiction, fostering a very rapid transition from occasional drug use to addiction, through mechanisms of negative reinforcement. The resulting addictive behavior-related ALs, in turn, may contribute to illness progression. This framework could have a heuristic value to enhance research on pathophysiology and treatment of BD and addiction comorbidity. PMID:25520673

    Bipolar disorder (BD) is a chronic and progressive psychiatric illness characterized by mood oscillations, with episodes of mania and depression. The impact of BD on patients can be devastating, with up to 15% of patients committing suicide. This disorder is associated with psychiatric and medical comorbidities and patients with a high risk of drug abuse, metabolic and endocrine disorders and vascular disease. Current knowledge of the pathophysiology and molecular mechanisms causing BD is still modest. With no clear biological markers available, early diagnosis is a great challenge to clinicians without previous knowledge of the longitudinal progress of illness. Moreover, despite recommendations from evidence-based guidelines, polypharmacy is still common in clinical treatment of BD, reflecting the gap between research and clinical practice. A major challenge in BD is the development of effective drugs with low toxicity for the patients. In this review article, we focus on the progress made and future challenges we face in determining the pathophysiology and molecular pathways involved in BD, such as circadian and metabolic perturbations, mitochondrial and endoplasmic reticulum (ER) dysfunction, autophagy and glutamatergic neurotransmission; which may lead to the development of new drugs.

    Recent studies provide considerable evidence that schizophrenia and bipolar disorder may share overlapping etiologic determinants. Identifying disease-related genetic effects is a major focus in schizophrenia and bipolar disorder research, with implications for clarifying diagnosis and developing specific treatments for various impairments in these 2 disorders. Efforts have been multifaceted, with the ultimate goal of describing causal paths from specific genetic variants, to changes in neuro...

    The current study aims to quantify characteristic features of bipolar flux appearance of solar intranetwork (IN) magnetic elements. To attack such a problem, we use the Narrow-band Filter Imager (NFI) magnetograms from the Solar Optical Telescope (SOT) on board \\emph{Hinode}; these data are from quiet and an enhanced network areas. Cluster emergence of mixed polarities and IN ephemeral regions (ERs) are the most conspicuous forms of bipolar flux appearance within the network. Each of the clus...

    Background/Aim. Bipolar affective disorder is mental disorder with polygenic type of heredity. Heritability - relation between genetic and environmental variance is used to estimate the level of influence of genetic variance to phenotype variance. Study results show decreasing trend in the value of heritability of bipolar affective disorder, thus indicating that this disorder is a complex behavioral threshold characteristic. Therefore, the aim of this study was to estimate the contribut...

    VESTIC technology is an alternative for traditional CMOS technology. This paper presents first measurement data of prototypes of VES-BJT: bipolar transistors in VESTIC technology. The VES-BJT is a bipolar transistor on the SOI substrate with symmetric lateral structure and both emitter and collector made of polysilicon. The results indicate that VES-BJT can be a device with useful characteristics. Therefore, VESTIC technology has the potential to become a new BiCMOS-type technology with some unique properties.

  13. Rumination in bipolar disorder: evidence for an unquiet mind

    Full Text Available Abstract Depression in bipolar disorder has long been thought to be a state characterized by mental inactivity. However, recent research demonstrates that patients with bipolar disorder engage in rumination, a form of self-focused repetitive cognitive activity, in depressed as well as in manic states. While rumination has long been associated with depressed states in major depressive disorder, the finding that patients with bipolar disorder ruminate in manic states is unique to bipolar disorder and challenges explanations put forward for why people ruminate. We review the research on rumination in bipolar disorder and propose that rumination in bipolar disorder, in both manic and depressed states, reflects executive dysfunction. We also review the neurobiology of bipolar disorder and recent neuroimaging studies of rumination, which is consistent with our hypothesis that the tendency to ruminate reflects executive dysfunction in bipolar disorder. Finally, we relate the neurobiology of rumination to the neurobiology of emotion regulation, which is disrupted in bipolar disorder.
