Abstract null null Introduction null Bright light therapy (BLT) has been used for treating seasonal affective disorder, depression and bipolar depression. However, it's precise mechanism remains unclear. Bright light exposure (BL) induces neurogenesis in the adult rat hippocampal dentate gyrus (DG). We hypothesized that BL may induce neurogenesis in the human DG as well. null null null Method null A 4-week randomized controlled trial study was conducted, where healthy participants were randomly ...

Abstract null null Hypothyroidism is a condition that affects multiple systems, including the central nervous system, causing, for example, cognitive deficits closely related to Alzheimer's disease. The flavonoid chrysin is a natural compound associated with neuronal improvement in several experimental models. Here, we evaluated the effect of chrysin on cognitive impairment in hypothyroid female mice by exploring neuroplasticity. Hypothyroidism was induced by continuous exposure to 0.1% methimaz...

Abstract null null Nonsuicidal self-injury (NSSI) typically occurs in the presence of negative emotions. Prior research has emphasized interpersonal stress as a specific context that may elevate negative emotions in this population and even increase the likelihood of NSSI behavior. However, the factors that contribute to the relationship between interpersonal stress and NSSI have received relatively limited attention. The current pilot study aimed to experimentally examine interpersonal problem-...

Abstract null null Gambling disorder creates a significant public health burden. Despite decades of clinical trials, there are no licensed pharmacological treatments for gambling disorder. Contributing factors to this are the high placebo response rates seen in clinical trials, the heterogeneity of the disorder and high rates of psychiatric comorbidities. Indeed, a number of demographic and clinical variables have previously been associated with altered responses to pharmacotherapy, psychotherap...

Abstract null null The severity of major depressive disorder (MDD) can be aggravated by gastrointestinal (GI) symptoms, but the neuroimaging mechanism underlying GI symptoms still remains unclear. In this study, we recruited 52 medication-free and first-episode MDD patients (35 with GI symptoms and 17 without GI symptoms) and 28 age-, sex-, and education-matched healthy controls to explore the inter-group differences in neuroimaging findings. All the participants underwent resting-state function...
Abstract null null Background null Risk factors and comorbidities associated with depression vary with age and must be considered when selecting appropriate anti-depressant medication for patients. Studies are lacking which focus both on treatments prescribed and include a broad age spectrum. The goal of this study was to investigate whether age of patients at diagnosis impact the type of antidepressant drug class prescribed. null null null Methods null This retrospective cohort study based on t...

Abstract null null Decreased mismatch negativity (MMN) is a proposed biomarker for psychotic disorders. However, the magnitude of the effect appears to be attenuated in first-episode populations. Furthermore, how mismatch negativity amplitudes are related to brain connectivity in this population is unclear. In this study, we used high-density EEG to record duration-deviant MMN from 22 patients with first-episode psychosis (FEP) and 23 age-matched controls (HC). Consistent with past work, we foun...

Abstract null null Background null Individuals with schizophrenia exhibit deficits in visual contrast processing, though less is known about how these deficits impact neurocognition and functional outcomes. This study investigated effects of contrast sensitivity (CS) on cognition and capacity for independent living in schizophrenia. Methods: Participants were 58 patients with schizophrenia (n = 49) and schizoaffective disorder (n = 9). Patients completed a psychophysical paradigm to obtain CS wi...

BACKGROUND Suicide bereavement is associated with increased risk for severe negative mental health outcomes and suicidality. The purpose of this study was to examine the association between mental health symptoms and suicidal ideation among suicide bereaved while taking multiple factors into account. METHODS The sample consisted of N = 157 German suicide bereaved who were interested in receiving an online intervention. The Beck Scale for Suicide Ideation (BSS) was used to distinguish between par...

Abstract null null Insecure attachment has been suggested as a major risk factor for mental health problems as well as a key element for the development and trajectory of psychiatric disorders. The aim of this meta-analysis was to assess whether insecure attachment constitutes a global transdiagnostic risk factor in bipolar disorder, depression, and schizophrenia spectrum disorders. We conducted a PRISMA-based systematic quantitative review to explore the prevalence of insecure attachment among ...
