Identifying genetic variants influencing human brain structures may reveal new biological mechanisms underlying cognition and neuropsychiatric illness. The volume of the hippocampus is a biomarker of incipient Alzheimer's disease and is reduced in schizophrenia, major depression and mesial temporal lobe epilepsy. Whereas many brain imaging phenotypes are(More)
The Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Consortium is a collaborative network of researchers working together on a range of large-scale studies that integrate data from 70 institutions worldwide. Organized into Working Groups that tackle questions in neuroscience, genetics, and medicine, ENIGMA studies have analyzed neuroimaging(More)
IMPORTANCE Neuroticism is a pervasive risk factor for psychiatric conditions. It genetically overlaps with major depressive disorder (MDD) and is therefore an important phenotype for psychiatric genetics. The Genetics of Personality Consortium has created a resource for genome-wide association analyses of personality traits in more than 63,000 participants(More)
Childhood maltreatment and depressive disorders have both been associated with a dysregulation of the hypothalamic-pituitary-adrenal axis. The FKBP5 gene codes for a co-chaperone regulating the glucocorticoid-receptor sensitivity. Previous evidence suggests that subjects carrying the TT genotype of the FKBP5 gene single-nucleotide polymorphism (SNP)(More)
Dysregulations of the hypothalamic-pituitary-adrenal (HPA) axis have been implicated in the pathogenesis of depressive disorders and the corticotropin-releasing hormone (CRH) was found to modulate emotional memory consolidation. Recently, two studies have reported an interaction between childhood abuse and the TAT-haplotype of the CRH-Receptor Gene (CRHR1)(More)
BACKGROUND Based on biological interactions between the serotonergic system and the brain-derived neurotrophic factor (BDNF), BDNF is a plausible candidate for a gene-gene-environment interaction moderating the interaction between the s/l- promoter polymorphism of the serotonin transporter (5-HTTLPR) and childhood abuse. We tested the hypothesis of a(More)
BACKGROUND Although the prevalence of mental disorders and the demand for mental health services are increasing, little is known about the impact of personality-related factors on help-seeking among depressive individuals. We, therefore, investigated the relationship between the "Big Five" personality traits, resilience, alexithymia, childhood neglect or(More)
The impact of the promoter polymorphisms of the serotonin transporter (5-HTTLPR) on mood has been studied by two-way interaction models comprising one environmental factor and genotype variants. However, childhood abuse is assumed to be associated with different psychobiological long-term effects than adult traumatic events. Both types of trauma may(More)
OBJECTIVE There is a lack of a psychometrically sound screening questionnaire that assesses important dimensions of traumatic experiences during childhood and adolescence in a time-efficient way. Based on the German version of the "Childhood Trauma Questionnaire" (CTQ, 28 items) we developed a five-item self-report childhood trauma screener (CTS) that(More)
Studies examining the natural course of borderline personality disorder (BPD) over the life span have yielded declining prevalence rates in older age groups. However, there is evidence that different BPD symptoms have different longitudinal patterns, with impulsivity decreasing with advancing age and negative affect remaining stable into late adulthood.(More)
