Neuropsychological dysfunction is a well-established finding in individuals with bipolar disorder type I (BP-I), even during euthymic periods; however, it is less clear whether this also pertains to bipolar disorder type II (BP-II) or those with subthreshold states (SBP; subthreshold bipolar disorder), such as bipolar not otherwise specified (BP-NOS). Herein, we compare the literature regarding neuropsychological performance in BP-II vs BP-I to determine the extent of relative impairment, and we present and review all related studies on cognition in SBP. After systematically searching PubMed, Medline, PsycINFO, and The Cochrane Library, we found 17 papers that comprise all the published studies relevant for this review. The areas that are consistently found to be impaired in BP are executive function, verbal memory, visual spatial working memory, and attention. More studies than not show no significant difference between BP-I and BP-II, particularly in euthymic samples. Preliminary evidence suggests that patients experiencing major depressive episodes who also meet criteria for SBP show similar profiles to BP-II; however, these results pertain only to a depressed sample. SBP were found to perform significantly better than both MDD and healthy controls in a euthymic sample. A consensus on mood state, patient selection, and neuropsychological testing needs to be agreed on for future research. Furthermore, no studies have used the most recent DSM-5 criteria for SBP; future studies should address this. Finally, the underlying bases of cognitive dysfunction in these diagnostic groups need to be further investigated. We suggest recommendations on all of the above current research challenges.

IntroductionThe difficulties of diagnosis and clinical differentiation of bipolar disorders, schizophrenia and schizoaffective disorder have been repeatedly noted both foreign and Russian authors.ObjectivesFull medico-psychological service clinical documentation research, including bipolar disorder patient records.AimsDetermination of bipolar disorders in accordance with the DSM-5 criteria among psychiatric outpatients.MethodsA group of 142 patients with established according to ICD-10 diagnoses: schizophrenia, schizoaffective disorder 137 (96.5%); the average patient's age 50 ± 13 and bipolar disorder and mania episode 5 (3.5%) – 55.4 ± 14.4 has been investigated.ResultsIt was found that 18 (12.7%) of all patients meet the DSM-5 bipolar disorder criteria compared with the primary diagnosis (3.5%). Structure of the diagnosis of bipolar disorder was represented as follows: bipolar disorder type I – 11 (61.2%), bipolar disorder type II – 7 (38.8%). Consequently, due to formal application DSM-5 bipolar disorder criteria BD determination 3.5 times more.ConclusionTraditionally, the diagnosis of schizophrenia is preferred over bipolar disorder. Manic episode in bipolar disorder can be evidently regarded as an acute schizophrenia manifestation. The diagnostic criteria for DSM-5 are convenient in diagnostics of manic and depressive episodes in case of their combination in I type bipolar disorder.Disclosure of interestThe authors have not supplied their declaration of competing interest.

AbstractRisk-taking behavior and impulsivity are core features of bipolar disorder. Whether they are part of the inherited aspect of the illness is not clear. We aimed to evaluate risk-taking behavior as a potential endophenotype for bipolar disorders, and its relationship with impulsivity and illness features. The Balloon Analogue Risk Task (BART) and Barratt Impulsiveness Scale-11 (BIS-11) were used to assess risk-taking behavior and impulsivity respectively in 30 euthymic bipolar I patients (BD), their 25 asymptomatic first-degree relatives (BD-R), and 30 healthy controls (HC). The primary BART outcome measure was the behavioral adjustment score (number of pumps after trials where the balloon did not pop minus the number of pumps after trials where the balloon popped). BD (p< .001) and BD-R (p= .001) had similar and significantly lower adjustment scores than HC. Only BD scored significantly higher on BIS-11 total (p= .01) and motor (p= .04) subscales than HC. Neither the BART, nor impulsivity scores associated with illness features. A limitation of this study is medicated patients and a heterogeneous BD-R were included. Riskiness may be a candidate endophenotype for bipolar disorder as it appears independently from illness features, presents similarly in BD and BD-R groups and differs from impulsivity.

IntroductionTo date, the proposition of recurrence as a subclinical bipolar disorder feature has not received adequate testing.Objectives/AimsWe used the Italian version of the bipolar spectrum diagnostic scale (BSDS), a self-rated questionnaire of bipolar risk, in a sample of patients with mood disorders to test its specificity and sensitivity in identifying cases and discriminating between high risk for bipolar disorder major depressive patients (HRU) and low risk (LRU) adopting as a high recurrence cut-off five or more lifetime major depressive episodes.MethodsWe included 115 patients with DSM-5 bipolar disorder (69 type I, 41 type II, and 5 NOS) and 58 with major depressive disorder (29 HRU and 29 LRU, based on the recurrence criterion). Patients filled-out the Italian version of the BSDS, which is currently undergoing a validation process.ResultsThe BSDS, adopting a threshold of 14, had 84% sensitivity and 76% specificity. HRU, as predicted, scored on the BSDS intermediate between LRU and bipolar disorder. Clinical characteristics of HRU were more similar to bipolar disorder than to LRU; HRU, like bipolar disorder patients, had more lifetime hospitalizations, higher suicidal ideation and attempt numbers, and higher rates of family history of suicide.ConclusionsThe BSDS showed satisfactory sensitivity and sensitivity. Splitting the unipolar sample into HRU and LRU, on the basis of the at least 5 lifetime major depressive episodes criterion, yielded distinct unipolar subpopulations that differ on outcome measures and BSDS scores.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Introdution:Our study represents a pilot evaluation about how the MOOD-SR recognizes subthreshold manifestations that may be associated with clinical symptomatology in a group of bipolar patients.Methods:At Day Hospital of Psychiatry, Policlinico “A. Gemelli”, Bipolar Disorders Unit, it has been conducted an experimental study on a heterogeneous sample of 24 patients with a diagnosis of Bipolar Disorder type I. Patients have been assessed with the MOOD-SR, a clinical self-reported interview, that is specific for the spectrum of subthreshold pathology, and with the Quality of Life (QoL), that investigates the patient's quality of life.Results:We have found that 16 patients on 24 report a score higher than 60 (68,4%). Among these, 10 female patients on 15 have a total score higer than 61 (68.75%) while 6 male patients on 9 obtain a total score higher than 60 (62,5%). However, these results have only preliminary value, further studies are needed in order to obtain a deeper evaluation.Conclusion:Spectrum manifestations are both indicator of course and response to treatment and predictive for relapse. This finding may represent an important preventive instrument for maniacal relapse in patients with Bipolar Disorder, that is often underdiagnosed or confused for Unipolar Depression. By adequately recognizing the problem we will be able to refine diagnosis and individualize therapy.

A comparison of the symptomatic profile between two consecutive depressive episodes in patients with bipolar disorder type I.Objective:To compare the variability of patterns of depressive symptoms between two consecutive depressive episodes in patients with bipolar disorder type I.Methods:Review of prospectively collected data from 136 subjects of an out-patient bipolar unit from 1997 to 2007. Binomial statistics was used for the analysis of Hamilton Depression Rating Scale (HDRS)-31 items of the first and second episodes, and the correlation of the HDRS-31 item scores of both episodes was determined using the Spearman coefficient.Results:Ten depressive symptoms showed a significant correlation between index and subsequent episodes: psychological anxiety, somatic anxiety, somatic symptoms, diurnal variation, paranoid symptoms, obsessive and compulsive symptoms, hypersomnia, loss of appetite and helplessness. Only four symptoms were stable in both statistical tests: paranoid symptoms, obsessive–compulsive symptoms, loss of appetite and hypersomnia.Conclusions:Paranoid and obsessive–compulsive symptoms, loss of appetite and hypersomnia tended to be found in successive episodes. However, the moderate correlations of the symptoms across two depressive recurrences suggested that clinical presentations in bipolar depression may not be predicted by symptom profiles presented in previous episodes.

Objective: Bipolar disorders are among the most common chronic mental disorders. Despite the recent improvement in controlling psychiatric disorders, treatment of bipolar disorders remains a challenge. The aim of this study was to determine the effect of consuming probiotics in patients with bipolar disorder-type 1 compared to the placebo group. Method: This was a permuted blocked randomized clinical trial conducted in Shahid Beheshti mental hospital in Kerman, Iran, from October 2017 to October 2018. Two psychiatrists diagnosed and hospitalized all 38 patients with type 1 bipolar disorder based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Using blind randomized blocking method size 4, patients were divided into 2 groups of placebo and probiotic. Young Mania Rating Scale (YMRS) and Hamilton's Depression Rating Scale (HDRS) were completed at the beginning, week 4, and week 8 of the study by a psychiatry resident. Independent t test, Mann-Whitney and repeated measures ANOVA tests were used. Data were analyzed using SPSS software version 20. Results: There was no significant difference between the 2 groups in age, sex, and severity of mania and depression. Consumption of probiotics reduced the scores of YMRS and HDRS over time in the probiotic group more than the placebo group, but it was not significant. Conclusion: Consumption of probiotics had non-significant effects on improvement and treatment of bipolar type 1 patients. It is suggested that future studies be conducted with different probiotic microbial strains and longer period of treatment.

Abstract Background This study aimed to compile and synthesize studies investigating explicit emotion regulation in patients with bipolar disorder and individuals at risk of developing bipolar disorder. The importance of explicit emotion regulation arises from its potential role as a marker for bipolar disorders in individuals at risk and its potent role in therapy for bipolar disorder patients. Methods To obtain an exhaustive compilation of studies dealing specifically with explicit emotion regulation in bipolar disorder, we conducted a systematic literature search in four databases. In the 15 studies we included in our review, the emotion-regulation strategies maintenance, distraction, and reappraisal (self-focused and situation-focused) were investigated partly on a purely behavioral level and partly in conjunction with neural measures. The samples used in the identified studies included individuals at increased risk of bipolar disorder, patients with current affective episodes, and patients with euthymic mood state. Results In summary, the reviewed studies' results indicate impairments in explicit emotion regulation in individuals at risk for bipolar disorder, patients with manic and depressive episodes, and euthymic patients. These deficits manifest in subjective behavioral measures as well as in neural aberrations. Further, our review reveals a discrepancy between behavioral and neural findings regarding explicit emotion regulation in individuals at risk for bipolar disorders and euthymic patients. While these groups often do not differ significantly in behavioral measures from healthy and low-risk individuals, neural differences are mainly found in frontostriatal networks. Conclusion We conclude that these neural aberrations are a potentially sensitive measure of the probability of occurrence and recurrence of symptoms of bipolar disorders and that strengthening this frontostriatal route is a potentially protective measure for individuals at risk and patients who have bipolar disorders.

AbstractThe presentations and clinical courses of patients with bipolar disorder differ greatly by gender. In addition, medical therapy must be tailored differently for men and women because of emerging safety concerns unique to the female reproductive system. In November 2005, these topics were explored by a panel of experts in psychiatry, neurology, and reproductive health at a closed roundtable meeting in Dallas, Texas. This clinical information monograph summarizes the highlights of that meeting.Compared to men with bipolar disorder, women have more pervasive depressive symptoms and experience more major depressive episodes. They are also at higher risk for obesity and certain other medical and psychiatric comorbidities. Mood changes across the menstrual cycle are common, although the severity, timing, and type of changes are variable. Bipolar disorder is frequently associated with menstrual abnormalities and ovarian dysfunction, including polycystic ovarian syndrome. Although some cases of menstrual disturbance precede the treatment of bipolar disorder, it is possible that valproate and/or antipsychotic treatment may play a contributory role in young women.Pregnancy does not protect against mood episodes in untreated women. Maintenance of euthymia during pregnancy is critical because relapse during this period strongly predicts a difficult postpartum course. Suspending therapy in the first months of pregnancy may be an option for some women with mild-to-moderate illness, or those with a long history of euthymia during pre-pregnancy treatment. However, a mood stabilizer should be reintroduced either in the later stages of pregnancy or in the immediate postpartum period. Preliminary data suggest that fetal exposure to some mood stabilizers may raise the risk of major congenital malformations and neurodevelopmental delays. For women planning to become pregnant, clinicians may consider switching to other drugs before conception. The value and drawbacks of breastfeeding during treatment must be considered in partnership with the patient, with close monitoring of nursing infants thereafter. The risks and benefits of medical treatment for women with bipolar disorder should be carefully reconsidered at each stage of their reproductive lives, with a flexible approach that is responsive to the changing needs of patients and their families.

ABSTRACTIntroduction: An increasing amount of data suggests that dysregulation of the immune system, including the cytokine network, is associated with the etiology and pathophysiology of mood disorders. Genes encoding cytokines are highly polymorphic and single nucleotide polymorphisms, associated with increased or reduced cytokine production, have been described. The aim of this study was to define the genetic immunologic scenario associated with major depressive disorder (MDD) and bipolar disorder.Methods: Eighty-four Italian outpatients affected by bipolar disorder type I, bipolar disorder type II, or MDD, and 363 healthy controls were enrolled into the study. We analyzed allele and genotype distribution of −308 (G/A) tumor necrosis factor-α (TNF-α), +874 (T/A) interferon-γ (IFN-γ), -174 (G/C) interleukin (IL)-6, and −1082 (G/A) IL-10 promoter polymorphisms by Polymerase Chain Reaction Sequence Specific Primers technique.Results: We observed different genotype and allele distributions of TNF-α, IFN-γ, and IL-10 polymorphisms in the three groups of patients analyzed. In particular, bipolar II patients were characterized by an absence of adenine (A) high producer allele of TNF-α (P<.001) and a lower percentage of TT high producer genotype of IFN-γ (P <.001); bipolar I individuals showed reduced percentage of AA low producer genotype of IL-10 (P<.001). Both bipolar I and bipolar II patients not carrying guanine (G) high producer IL-6 allele showed a lower mean age at onset (P=.048).Conclusion: These data support the existence of a genetic profile related to pro-inflammatory cytokines in patients affected by mood disorders. The differences observed across the three clinical phenotypes suggest the presence of different pathogenetic mechanisms involved in the susceptibility of phenotypically different mood disorders.
