BACKGROUND: Schizophrenia (SZ) and bipolar disorder (BD) are considered neurobiological disorders which share some clinical, cognitive and neuroimaging characteristics. Studying child and adolescent offspring of patients diagnosed with bipolar disorder (BDoff) or schizophrenia (SZoff) is regarded as a reliable method for investigating early alterations and vulnerability factors for these disorders. This study compares the neuropsychological characteristics of SZoff, BDoff and a community control offspring group (CC) with the aim of examining shared and differential cognitive characteristics among groups...

BACKGROUND: Childhood trauma increases risk of a range of mental disorders including psychosis. Whereas the mechanisms are unclear, previous evidence has implicated atypical processing of emotions among the core cognitive models, in particular suggesting altered attentional allocation towards negative stimuli and increased negativity bias. Here, we tested the association between childhood trauma and brain activation during emotional face processing in patients diagnosed with psychosis continuum disorders...

Previous findings on the diagnostic validity and reliability of generalized anxiety disorder (GAD)-associated symptom criteria suggest need for further evaluation. The current study examined convergent validity and specificity of GAD-associated symptoms in a representative Singapore community sample. The Singapore of Mental Health Study a cross-sectional epidemiological survey conducted among 6166 Singapore residents aged 18 and older. The Composite International Diagnostic Interview version 3.0 was used to diagnose mental disorders...

Frontotemporal degeneration (FTD) in its behavioral variant (bvFTD) is probably one of the conditions that best illustrates the links between psychiatry and neurology. It is indeed admitted that between a third and half of patients with this condition, especially in early-onset forms, receive an initial diagnosis of psychiatric disorder (depression, schizophrenia, bipolar disorder) and are then referred to a psychiatric ward. BvFTD can thus be considered a neurological disorder with a psychiatric presentation...

BACKGROUND: This study aimed to identify how the activity of large-scale brain networks differs between mood states in bipolar disorder. The authors measured spontaneous brain activity in subjects with bipolar disorder in mania and euthymia and compared these states to a healthy comparison population. METHODS: 23 subjects with bipolar disorder type I in a manic episode, 24 euthymic bipolar I subjects, and 23 matched healthy comparison (HC) subjects underwent resting state fMRI scans...

The diagnosis of bipolar disorder (BD) in youth is confusing and controversial. Controversy notwithstanding, youth diagnosed with BD have high behavioral health needs and are at elevated risk for problematic long-term psychosocial functioning and complex psychiatric medication regimens. Pediatricians and other primary care providers (PCPs) can play an important role in the assessment and treatment of youth diagnosed with BD and the recently created and also controversial diagnosis of disruptive mood dysregulation disorder (DMDD)...

Major depressive and bipolar disorders predispose to atherosclerosis, and there is accruing data from animal model, epidemiological, and genomic studies that commonly used antihypertensive drugs may have a role in the pathogenesis or course of mood disorders. In this study, we propose to determine whether antihypertensive drugs have an impact on mood disorders through the analysis of patients on monotherapy with different classes of antihypertensive drugs from a large hospital database of 525 046 patients with follow-up for 5 years...

Children of a parent with bipolar disorder (bipolar offspring) have an increased risk for mood disorders. While genetic factors play a significant role in this population, susceptibility to environmental stress may also significantly contribute to this vulnerability for mood disorders. Childhood trauma has consistently been found to increase the risk for mood disorders, with persisting consequences for hypothalamic-pituitary-adrenal (HPA) axis functionality. However, it is currently unknown whether childhood trauma specifically affects HPA axis activity in individuals with a familial risk for bipolar disorder...

Psychotic disorders affect ~3% of the general population and are among the most severe forms of mental diseases. In early stages of psychosis, clinical aspects may be difficult to distinguish from one another. Undifferentiated psychopathology at the first-episode of psychosis (FEP) highlights the need for biomarkers that can improve and refine differential diagnosis. We investigated gene expression differences between patients with FEP-schizophrenia spectrum (SCZ; N=53) or FEP-Mania (BD; N=16) and healthy controls (N=73)...

OBJECTIVE: We aimed to evaluate the Child Behavior Checklist (CBCL) profiles in youths with bipolar and depressive disorders. METHODS: 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)...

Improved clinical care for Bipolar Disorder (BD) relies on the identification of diagnostic markers that can reliably detect disease-related signals in clinically heterogeneous populations. At the very least, diagnostic markers should be able to differentiate patients with BD from healthy individuals and from individuals at familial risk for BD who either remain well or develop other psychopathology, most commonly Major Depressive Disorder (MDD). These issues are particularly pertinent to the development of translational applications of neuroimaging as they represent challenges for which clinical observation alone is insufficient...

There is a high rate of misdiagnosis between major depressive disorder (MDD) and bipolar disorder (BD) in clinical practice. Our previous work provided suggestive evidence for brain-derived neurotrophic factor (BDNF) in differentiating BD from MDD. In this study, we aimed to investigate the role of mature BDNF (mBDNF) and its precursor (proBDNF) in distinguishing bipolar depression (BP) from MDD during acute depressive episode. A total of 105 participants, including 44 healthy controls, 37 MDD patients and 24 BP patients, were recruited...

OBJECTIVE: The differential diagnosis of bipolar illness vs. borderline personality is controversial. Both conditions manifest impulsive behavior, unstable interpersonal relationships, and mood symptoms. This study examines whether and which mood clinical features can differentiate between both conditions. METHOD: A total of 260 patients (mean ± standard deviation age 41 ± 13 years, 68% female) attending to a mood clinic were examined for diagnosis of bipolar illness and borderline personality disorder using SCID-I, SCID-II, and clinical mood criteria extracted from Mood Disorder Questionnaire (MDQ)...

SNAP-25 is a neurotransmitter vesicular docking protein which has been associated with brain disorders such as attention deficit hyperactivity disorder, bipolar disorder and schizophrenia. In this project, we were interested if clinical factors are associated with differential SNAP-25 expression. We examined the SNAP-25 isoform mRNA and protein levels in postmortem cortex Brodmann's area 9 (BA9) and BA24 (n = 29). Subjects were divided by psychiatric diagnosis, clinical variables including mood state in the last week of life and lifetime impulsiveness...

OBJECTIVE: It is difficult to distinguish between bipolar disorder and major depressive disorder (MDD) in patients lacking a clear history of mania. There is an urgent need for an objective biomarker for differential diagnosis. Using diffusion tensor imaging, this study investigated the differences in the brain white matter microstructure between patients with bipolar disorder and MDD. METHODS: Participants included 16 patients with bipolar disorder and 23 patients with MDD having depressed or euthymic states based on DSM-IV-TR criteria and 23 healthy volunteers...

Diagnosing a pediatric patient with bipolar disorder can pose a challenge for clinicians. Children typically do not present with the full criteria for a mood episode and may have symptoms of other disorders such as attention-deficit/hyperactivity disorder, oppositional defiant disorder, anxiety disorders, and other mood disorders, which may complicate the diagnostic process. By diligently interviewing parents and children about behaviors, thoroughly reviewing family histories, and systematically ruling out other disorders, clinicians can provide an accurate diagnosis for their pediatric patients...

We report two cases of adults who developed mania after taking the antibiotic clarithromycin. Clarithromycin is a frequently used antibiotic, but it can lead to a rare but significant psychiatric complication in the form of a manic episode. Mania is commonly associated with bipolar disorder, but the causes can be pharmacological, metabolic or neurologic, particularly when it occurs in patients who themselves or whose families have no past history of psychiatric illness. New-onset mania calls for detailed clinical and laboratory testing and neuro-imaging so that somatic causes can be ruled out...

BACKGROUND: The difference of burden between caregivers of acute patients with schizophrenia and bipolar disorder has not been well studied in China, a culture where family responsibility has a very high value. Our aim is to compare family burden in these two categories diagnosis and to identify predictors of family burden in a large psychiatric hospital in China. METHODS: Two hundred forty-three schizophrenic patients and 200 bipolar patients were enrolled in a cross-sectional study...

Schizoaffective disorder is a common diagnosis in clinical practice but its nosological status has been subject to debate ever since it was conceptualized. Although it is key that diagnostic reliability is sufficient, schizoaffective disorder has been reported to have low interrater reliability. Evidence based on systematic review and meta-analysis methods, however, is lacking. Using a highly sensitive literature search in Medline, Embase, and PsycInfo we identified studies measuring the interrater reliability of schizoaffective disorder in comparison to schizophrenia, bipolar disorder, and unipolar disorder...

Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively was found to be a thrombosed epidural varix compressing the nerve root preoperatively...
