It is not surprising to find microbiome abnormalities present in psychiatric disorders such as depressive disorders, bipolar disorders, etc. Evolutionary pressure may provide an existential advantage to the host eukaryotic cells in that it survives in an extracellular environment containing non-self cells (e.g., bacteria). This phenomenon is both positive and negative, as with other intercellular processes. In this specific case, the phenomenal amount of information gained from combined bacterial genome could enhance communication between self and non-self cells...

BACKGROUND: Suicide and mood disorders (especially major depressive disorder (MDD) and bipolar affective disorder (BD)) represent a significant global health burden. Major depressive disorder and bipolar affective disorder have been associated with increased risk for suicide. Some specific suicide risk factors might be found in underlying individual personality traits. Specific personality features may predispose an individual to mood disorders (MDD or BD) hence increased suicide risk...

BACKGROUND: Schizophrenia (SZ) and bipolar disorder (BD) are traditionally distinguished on the basis of progressive deterioration and long-term outcome, but a more dimensional approach is warranted. There are limited data on the occurrence of manic symptoms in patients with schizophrenia. The aim of the current study was to search for patterns in the clinical symptomatology, which may suggest the presence of one or several mood disorders under the label of schizophrenia. SUBJECTS AND METHODS: Hundred-seventy-five patients diagnosed with schizophrenia according to DSM-5 were included in the study...

BACKGROUND: Although inflammatory cytokines are established biomarkers of mood disorders, their molecular mechanism is not known. We hypothesized that circulating mitochondrial DNA (mtDNA) contributes to inflammation and could be used as biomarkers. We investigated if circulating mtDNA level is associated with inflammatory cytokines and can be used as a biomarker of mood disorders. METHODS: Plasma mtDNA concentration was measured with real-time quantitative PCR targeting two regions of the mtDNA and plasma levels of four cytokines (GM-CSF, IL-2, IL-4, and IL-6) were measured with a multiplex immunoassay method in 109 patients with major depressive disorder (MDD)...

Borderline personality disorder (BOR) is determined by environmental and genetic factors, and characterized by affective instability and impulsivity, diagnostic symptoms also observed in manic phases of bipolar disorder (BIP). Up to 20% of BIP patients show comorbidity with BOR. This report describes the first case-control genome-wide association study (GWAS) of BOR, performed in one of the largest BOR patient samples worldwide. The focus of our analysis was (i) to detect genes and gene sets involved in BOR and (ii) to investigate the genetic overlap with BIP...

Introduction Bipolar disorder (BD) is a chronic, highly disabling condition associated with psychiatric/medical comorbidity and substantive morbidity, mortality, and suicide risks. In prior reports, varying parameters have been associated with suicide risk. OBJECTIVES: To evaluate sociodemographic and clinical variables characterizing Italian individuals with BD with versus without prior suicide attempt (PSA). METHODS: A sample of 362 Italian patients categorized as BD according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM IV-TR) was assessed and divided in 2 subgroups: with and without PSA...

Schizophrenia (SCZ), bipolar disorder (BD) and recurrent major depressive disorder (rMDD) are common psychiatric illnesses. All have been associated with lower cognitive ability, and show evidence of genetic overlap and substantial evidence of pleiotropy with cognitive function and neuroticism. Disrupted in schizophrenia 1 (DISC1) protein directly interacts with a large set of proteins (DISC1 Interactome) that are involved in brain development and signaling. Modulation of DISC1 expression alters the expression of a circumscribed set of genes (DISC1 Regulome) that are also implicated in brain biology and disorder...

BACKGROUND: Bipolar disorder types I (BD I) and II (BD II) might present different dysfunctions of the cortex and brainstem, as reflected by the second exteroceptive suppression period of temporalis muscle activity (ES2) under different stimuli of external emotions. METHODS: This study included 30 BD I and 20 BD II patients, and 40 healthy volunteers. All participants were invited to answer the Mood Disorder Questionnaire, the Hypomania Checklist-32, and the Plutchik-van Praag Depression inventory, as well as to undergo the ES2 test under external emotional-stimuli (emotional pictures plus sounds) of Disgust, Erotica, Fear, Happiness, and Sadness...

Objective Despite many women suffering from psychosis in their childbearing years, limited data exist about the use of atypical antipsychotic agents in pregnancy. Atypical antipsychotic agents are often used to treat bipolar disorder, instead of lithium or valproate because of the known teratogenicity of those agents. As well, atypical antipsychotics are often prescribed in anxiety disorders and depression. This study sought to describe pregnancy outcomes for women prescribed atypical antipsychotics during pregnancy...

The aim of this research was to study the role and trend of antidepressant use as a method of suicide in completed self-poisoning suicides in patients with affective disorders during a 23-year follow up period. The data consisted of 483 completed self-poisoning suicides from 1988 to 2011 in the province of Oulu in Northern Finland (286 men and 197 women). Of the self-poisoning victims, 26.9% (n=130) had hospital-treated unipolar depression and 3.1% (n=15) hospital-treated bipolar disorder. Further, 53.8% (n=70) of those with unipolar depression and 53...

BACKGROUND: It is common for patients with bipolar disorder (BP) to receive multiple psychotropics, but few studies have assessed demographic and clinical features associated with risk for receiving complex psychotropic polypharmacy. METHODS: This longitudinal cohort study examined 2712 inpatients with a DSM-IV clinical diagnosis of BP to assess associations between complex polypharmacy (defined as ≥4 psychotropics) and demographic and clinical features; associations with risk of rehospitalization were also examined...

BACKGROUND: Genome-wide association studies in adults have identified numerous genetic variants related to psychiatric disorders and related traits, such as schizophrenia and educational attainment. However, the effects of these genetic variants on behaviour in the general population remain to be fully understood, particularly in younger populations. We investigated whether polygenic scores of five psychiatric disorders and educational attainment are related to emotional and behaviour problems during early childhood...

Identifying brain differences and similarities between bipolar disorder (BD) and major depressive disorder (MDD) is necessary for increasing our understanding of the pathophysiology and for developing more effective treatments. However, the features of whole-brain intrinsic functional connectivity underlying BD and MDD have not been directly compared. We collected resting-state fMRI data from 48 BD patients, 48 MDD patients, and 51 healthy subjects. We constructed voxel-wise whole-brain functional networks and computed regional functional connectivity strength (FCS) using graph-theory and further divided the regional FCS into long-range FCS (lFCS) and short-range FCS (sFCS)...

BACKGROUND: Unipolar and bipolar disorder combined account for nearly half of all morbidity and mortality due to mental and substance use disorders, and burden society with the highest health care costs of all psychiatric and neurological disorders. Among these, costs due to psychiatric hospitalization are a major burden. Smartphones comprise an innovative and unique platform for the monitoring and treatment of depression and mania. No prior trial has investigated whether the use of a smartphone-based system can prevent re-admission among patients discharged from hospital...

BACKGROUND: The current categorical split of mood disorders in bipolar (BP) disorders and depressive disorders has recently been questioned. The presence of a significant number of manic/hypomanic symptoms in patients with recurrent unipolar depression seems to challenge the traditional dichotomy of unipolar-BP disorder. Two highly unstable personality features, i.e., the cyclothymic temperament (CT) and borderline personality disorder, have been found to be more common in BP disorder than in major depressive disorder...

OBJECTIVES: Having a parent with bipolar disorder (BP) is a very strong risk factor for developing BP. Similarly, depression among youth is a clinical risk factor for subsequent BP. We evaluated whether mood symptomatology in depressed youth is different between those at high and low familial risk to develop BP. METHODS: The most severe major depressive episode in BP offspring (N=61) and community control offspring (N=20) was evaluated using expanded depression and mania rating scales derived from the Schedule for Affective Disorders and Schizophrenia for Children Present Version...
