BACKGROUND: Bipolar disorder (BD) has been associated with dysfunctional resting-state brain functioning. However, it is still not known whether the aberrant functioning occurs and predict cognitive functioning before illness onset. AIMS: We examined the resting-state regional and network dysfunctioning, and their correlates with neurocognitive performance, in the high-risk (HR) and ultra-high-risk (UHR) stages of bipolar disorder. METHODS: Using amplitude of low-frequency fluctuations (ALFF), region homogeneity (ReHo) and hypothesis-driven region-of-interest (ROI)-based connectivity, we examined resting-state fMRI data of 8- to 25-year-old healthy offspring (HR, n = 28) and offspring with subthreshold syndromes (UHR, n = 22) of a BD parent, and age-matched healthy controls without any personal or family psychopathology (HC, n = 46)...

A substantial and variable placebo response can cause unreliable findings in clinical trials designed to demonstrate the efficacy of antidepressants, and the high rate of failed trials represents a major obstacle in the development of new drugs for major depressive disorder (MDD). However, the influence of demographic and symptom factors on the antidepressant effect remains to be established. The purpose of this study was to estimate the magnitude of this influence. A patient-level meta-analysis of data from double-blind, randomized, placebo-controlled trials involving the use of antidepressants for adults with MDD was performed...

Although sex differences in major depression have been reported repeatedly, the underlying mechanisms are still disputed. The rapidly changing gonadal steroid concentrations of the postpartum period or during menopause have been shown to be associated with depressive symptoms and to modulate the hypothalamic-pituitary-adrenal (HPA)-axis, which is implicated in depression. The sample comprised of 128 depressed in-patients (36.7% women) and 166 healthy controls (30.0% women). Blood was collected at baseline (at 6pm) and then 3 h as well as 21 h after ingestion of 1...

Poor sleep quality has been repeatedly linked to the entire psychosis continuum, including psychotic-like experiences (PLEs); however, sleep dysfunction is a component of several other psychopathologies that have also been linked to increased risk for PLEs, including depression, anxiety, and post-traumatic stress disorder (PTSD). It has yet to be examined if PLEs are a significant risk factor for poor sleep quality or if this sleep dysfunction is better accounted for by comorbid psychopathology. In 2687 undergraduates, PLEs were evaluated using the positive items of the Prodromal Questionnaire...

Megan L Rogers, Thomas E Joiner
Suicide-specific rumination, defined as a mental fixation on one's suicidal thoughts, intentions, and plans, may be an important predictor of suicidal behavior. To date, suicide-specific rumination has demonstrated convergence with, yet distinction from, a variety of suicide risk factors, and differentiated suicide attempters from ideators. However, no research has examined whether suicide-specific rumination is associated with lifetime suicide attempts above and beyond the presence of a host of other relevant suicide risk factors...

Posttraumatic stress disorder (PTSD) is a chronic, debilitating condition for which Prolonged Exposure (PE) therapy is highly efficacious. However, for some individuals, premature dropout and residual PTSD symptoms remain obstacles. The neuropeptide oxytocin is a promising candidate to enhance PE due to its ability to enhance 1) prosocial cognition and behavior, which are theorized to promote positive working alliance, and 2) extinction learning, which is the central mechanism of action underlying successful PE treatment...

Childhood maltreatment is associated with posttraumatic stress disorder (PTSD) and elevated rates of adolescent and adult psychopathology including major depression, bipolar disorder, substance use disorders, and other medical comorbidities. Gray matter volume changes have been found in maltreated youth with (versus without) PTSD. However, little is known about the alterations of brain structural covariance network topology derived from cortical thickness in maltreated youth with PTSD. High-resolution T1-weighted magnetic resonance imaging scans were from demographically matched maltreated youth with PTSD (N = 24), without PTSD (N = 64), and non-maltreated healthy controls (n = 67)...

Given the lack of effective biological markers for early diagnosis of bipolar mania, and the tendency for voice fluctuation during transition between mood states, this study aimed to investigate the speech features of manic patients to identify a potential set of biomarkers for diagnosis of bipolar mania. 30 manic patients and 30 healthy controls were recruited and their corresponding speech features were collected during natural dialogue using the Automatic Voice Collecting System. Bech-Rafaelsdn Mania Rating Scale (BRMS) and Clinical impression rating scale (CGI) were used to assess illness...

Anorexia nervosa (AN) is a severe mental disorder accompanied by extensive metabolic and endocrine abnormalities. It has been associated with hypercortisolism using short-term measurement methods such as 24 h-urine, saliva, and blood. The aim of this study was to examine whether the proposed hypercortisolism in acutely underweight AN (acAN) is also reflected in a long-term measure: hair cortisol (HCC). To gain further insight, we compared hair cortisol to a well-established classical cortisol measure (24 h-urine; UCC) longitudinally in acAN...

BACKGROUND: The brain-derived neurotrophic factor (BDNF) Val66Met polymorphism (rs6265) has been associated with several neuropsychiatric disorders and regional structural brain changes in adults, but little is known about Val66Met's effect on brain morphology during typical or atypical neurodevelopment. Windows of vulnerability to psychopathology may be associated with the different alleles of the Val66Met polymorphism during childhood and adolescence. METHODOLOGY: We investigated the effect of Val66Met on cortical thickness in MRI scans of 718 children and adolescents (6-12 years old) with typical development, and in those meeting DSM criteria for a psychiatric disorder...

Direct exposure to traumatic events often precipitates sleep disorders. Sleep disturbance has also been observed amongst those indirectly exposed to trauma, via mass media. However, previous work has focused on traditional media use, rather than contemporary social media. We tested associations between both traditional and social media consumption and insomnia symptoms following 2015 terror attacks in Paris France, controlling for location and post-traumatic symptomology. 1878 respondents, selected to represent the national French population, completed an internet survey a month after the Bataclan attacks (response rate 72%)...

Diffusional kurtosis imaging (DKI) and neurite orientation dispersion and density imaging (NODDI) are new diffusional magnetic resonance imaging (dMRI) techniques for the characterization of neural tissues in human brain. In this study, we used these dMRI techniques to evaluate the whole-brain microstructural changes in patients with major depressive disorder (MDD). Twenty-three patients with MDD and 26 healthy subjects underwent dMRI. We compared the dMRI metrics between the 2 groups and examined the relationships between the metrics and the clinical symptoms of MDD...

Pain has been linked with an increased risk of engaging in suicidal behavior. However, the role of common mental disorders (CMDs) and borderline personality disorder (BPD) traits in this association is largely unknown. This study was based on data from the 2007 Adult Psychiatric Morbidity Survey (N = 7403). Suicidal behavior referred to past 12-month suicidal ideation and suicide attempt. Pain was assessed in terms of the level of its interference with work activity in the past four weeks. BPD traits were assessed with the structured interview for DSM disorders questionnaire, and CMDs with the Clinical Interview Schedule Revised (CIS-R)...

Schizophrenia (SCZ) and bipolar disorder (BD) have high heritability. Genome-wide association studies (GWAS) have identified ZNF804A as a significant risk gene for both illnesses. A validation of this finding at the brain systems-level is imperative as there is still little understanding of how it heightens risk. Based in part on our recent findings of an effect on widespread decreased white matter microstructural fractional anisotropy (putatively a proxy of its integrity), particularly strong in SCZ, we asked whether the risk allele has a detrimental effect on regional brain activation and functional connectivity during a type of cognitive processing which is, together with its neural correlates, impaired in BD and SCZ: verbal fluency...

OBJECTIVES: Examine evidence for different subclasses of posttraumatic stress disorder (PTSD) symptoms in a sample of trauma exposed, low-income, predominantly African American men and women. Assess the relationship between PTSD subclasses with major depressive disorder (MDD) and types of trauma experienced. METHOD: Latent class analysis (LCA) using a multivariate normal mixture model on the 17-item PTSD Symptom Scale (PSS) was used to identify latent subclasses of PTSD symptoms (N = 5063)...

Many individuals who die by suicide or attempt suicide have no pre-existing psychiatric record. In these cases determination of the presence of mental illness at the time of the suicidal act depends on diagnostic interviews with different informants, but the reliability of such interviews is unknown. To address this issue, the current study from northern China conducted independent diagnostic interviews (by different psychiatrists) with a co-resident family member and another associate of 151 suicide decedents, with 120 individuals who attempted suicide, and with two proxy informants for each suicide attempter...

OBJECTIVE: Patients with schizophrenia have a higher prevalence of metabolic syndrome (MetS) than the general population. Minimizing weight gain and metabolic abnormalities in a population with an already high prevalence of obesity is of clinical and social importance. This randomized controlled trial investigated the effect of monthly nutritional education on weight change and metabolic abnormalities among patients with schizophrenia in Japan. METHODS: From July 2014 to December 2014, we recruited 265 obese patients who had a DSM-IV diagnosis of schizophrenia or schizoaffective disorder...

BACKGROUND: There is a growing concern over the addictiveness of Social Media use. Additional representative indicators of impaired control are needed in order to distinguish presumed social media addiction from normal use. AIMS: (1) To examine the existence of time distortion during non-social media use tasks that involve social media cues among those who may be considered at-risk for social media addiction. (2) To examine the usefulness of this distortion for at-risk vs...

The results of several epidemiological studies and clinical trials investigating the effects of n-3 polyunsaturated fatty acids (PUFAs) on antenatal and postnatal depression remain controversial. We investigated the possible association of dietary intake of fish and n-3 PUFAs with the risks of maternal and paternal psychological distress during pregnancy and of maternal postpartum depression in Japan. From a dataset comprising 104,102 maternal registrations and 52,426 paternal registrations in The Japan Environment and Children's Study, this study analyzed complete data on questionnaires for 75,139, 79,346, and 77,661 women during early pregnancy, mid-late pregnancy, and after pregnancy, respectively, and for 41,506 male partners...

Although benzodiazepines (BZDs) are commonly prescribed for insomnia or anxiety, long-term use of BZDs causes serious adverse effects such as daytime drowsiness and cognitive decline. In the current study, we evaluated the predictors and preventers of long-term usage of BZDs from a retrospective survey by utilizing the 12-year prescription record of a university hospital. From the prescription data of 92,005 people, users of BZDs (n = 3,470, male = 39.2%, mean age = 60 ± 17.5) were analyzed. During this period, both the number of prescriptions (2722 in 2004 to 1019 in 2016) and the number of BZDs (1...
