    Title translation Breakthrough in understanding the molecular causes of psychiatric disorders.
    Abstract A long-established hypothesis is that genetic factors contribute to the development of psychiatric diseases, including common illnesses such as schizophrenia and the affective disorders; however, reliable molecular identification of these factors represents a far more recent innovation. This has been rendered possible by technological advances in the individual characterization of the human genome and the combining of large genetic datasets at the international level. For the first time, the results of genome-wide analyses provide researchers with systematic insights into disease-relevant biological mechanisms. Here, the integrated analysis of different omics level data generates important insights into the functional interpretation of the genetic findings. The results of genetic studies also demonstrated the degree of etiological overlap between differing psychiatric disorders, with the greatest commonality having been observed to date between schizophrenia and bipolar affective disorder. Although the translation of genetic findings into routine clinical practice is being pursued at various levels, elaborate follow-up studies are typically necessary. The diagnostic investigation of rare genomic deletions/duplications (so-called copy number variants) in patients with schizophrenia is likely to represent one of the first examples of routine clinical application. The necessary prerequisites for this are currently being defined.

    Abstract: Aim: We investigated the predictive value of polygenic risk scores (PRS) derived from the schizophrenia GWAS (Trubetskoy et al., 2022) (SCZ3) for phenotypic traits of bipolar disorder type-I (BP-I) in 1878 BP-I cases and 2751 controls from Romania and ... ...

    Abstract Aim: We investigated the predictive value of polygenic risk scores (PRS) derived from the schizophrenia GWAS (Trubetskoy et al., 2022) (SCZ3) for phenotypic traits of bipolar disorder type-I (BP-I) in 1878 BP-I cases and 2751 controls from Romania and UK.
    Methods: We used PRSice-v2.3.3 and PRS-CS for computing SCZ3-PRS for testing the predictive power of SCZ3-PRS alone and in combination with clinical variables for several BP-I subphenotypes and for pathway analysis. Non-linear predictive models were also used.
    Results: SCZ3-PRS significantly predicted psychosis, incongruent and congruent psychosis, general age-of-onset (AO) of BP-I, AO-depression, AO-Mania, rapid cycling in univariate regressions. A negative correlation between the number of depressive episodes and psychosis, mainly incongruent and an inverse relationship between increased SCZ3-SNP loading and BP-I-rapid cycling were observed. In random forest models comparing the predictive power of SCZ3-PRS alone and in combination with nine clinical variables, the best predictions were provided by combinations of SCZ3-PRS-CS and clinical variables closely followed by models containing only clinical variables. SCZ3-PRS performed worst. Twenty-two significant pathways underlying psychosis were identified.
    Limitations: The combined RO-UK sample had a certain degree of heterogeneity of the BP-I severity: only the RO sample and partially the UK sample included hospitalized BP-I cases. The hospitalization is an indicator of illness severity. Not all UK subjects had complete subphenotype information.
    Conclusion: Our study shows that the SCZ3-PRS have a modest clinical value for predicting phenotypic traits of BP-I. For clinical use their best performance is in combination with clinical variables.

    Abstract Background: This study aims to identify covariates of suicidal ideation (SI) in a large sample of individuals diagnosed with social anxiety disorder (SAD).
    Methods: In a cross-sectional design, 305 individuals (38.4 ± 14.1 years, 59% female) with SAD were assessed by the Social Phobia Inventory, Beck Depression Inventory, Adverse Childhood Experience Questionnaire, State Trait Anger Expression Inventory, Beck Scale for Suicidal Ideation and the Interpersonal Needs Questionnaire.
    Results: SAD individuals with SI (n = 142, 46.6%) reported higher SAD and depression symptoms, more adverse childhood experiences (ACE), higher state anger (SA), perceived burdensomeness (PB) and higher thwarted belongingness (TB) compared to SAD individuals without SI (n = 163, 53.4%). In binary logistic regression, PB (odds ratio (OR) = 1.11, 95% confidence interval (CI) = 1.06-1.15), TB (OR = 1.05, 95% CI = 1.02-1.07), SA (OR = 1.07, 95% CI = 1.01-1.13) and ACE (OR = 1.18, 95% CI = 1.03-1.35) emerged as significant covariates of acute SI (Nagelkerke's R
    Limitations: Cross-sectional design and self-reporting measures limit generalization.
    Conclusion: Our findings confirm the validity of the Interpersonal Theory of Suicide concerning SI in SAD. PB and TB with SA and ACE may support the valid assessment of SI in therapeutic settings.

    Abstract Individuals with social anxiety disorder (SAD) often suffer from comorbid major depressive disorder (MDD), which goes along with increased clinical and functional impairment. There has been little research on underlying differences regarding childhood adversities and attachment styles between individuals with SAD with and without comorbid MDD. In the present study, the consecutive sample comprised 612 SCID-diagnosed participants. Of these, n = 472 (62.3% women, 40.7 ± 13.8 years) showed SAD and comorbid MDD (SAD-MDD group) and n = 140 (47.9% women, 43.7 ± 14.7 years) showed just SAD (SAD group). The two groups were compared regarding SAD symptom severity (Social Phobia Inventory; SPIN), childhood adversities (Adverse Childhood Experience Questionnaire; ACE) and attachment styles (Attachment Style Questionnaire, ASQ). The SAD-MDD group reported significantly more severe SAD symptoms (p = .002, d = 0.30), more childhood adversities (p < .001, d = 0.35) and a higher level of fearful attachment style (p < .001, d = 0.30). Group significantly moderated the association between fearful attachment style and SAD symptom severity (β = .292, p < .05) but not between preoccupied attachment style and SAD symptom severity (β = -.184, p = .124; R

    Abstract Purpose: BioMD-Y is a comprehensive biobank study of children and adolescents with major depression (MD) and their healthy peers in Germany, collecting a host of both biological and psychosocial information from the participants and their parents with the aim of exploring genetic and environmental risk and protective factors for MD in children and adolescents.
    Participants: Children and adolescents aged 8-18 years are recruited to either the clinical case group (MD, diagnosis of MD disorder) or the typically developing control group (absence of any psychiatric condition).
    Findings to date: To date, four publications on both genetic and environmental risk and resilience factors (including
    Future plans: Data collection is currently scheduled to continue into 2026. Research questions will be further addressed using available measures.

    Abstract Objectives: Bipolar disorder (BD) and major depressive disorder (MDD) are characterized by specific alterations of mood. In both disorders, alterations in cognitive domains such as impulsivity, decision-making, and risk-taking have been reported. Identification of similarities and differences of these domains in BD and MDD could give further insight into their etiology. The present study assessed impulsivity, decision-making, and risk-taking behavior in BD and MDD patients from bipolar multiplex families.
    Methods: Eighty-two participants (BD type I, n = 25; MDD, n = 26; healthy relatives (HR), n = 17; and healthy controls (HC), n = 14) underwent diagnostic interviews and selected tests of a cognitive battery assessing neurocognitive performance across multiple subdomains including impulsivity (response inhibition and delay aversion), decision-making, and risk behavior. Generalized estimating equations (GEEs) were used to analyze whether the groups differed in the respective cognitive domains.
    Results: Participants with BD and MDD showed higher impulsivity levels compared to HC; this difference was more pronounced in BD participants. BD participants also showed lower inhibitory control than MDD participants. Overall, suboptimal decision-making was associated with both mood disorders (BD and MDD). In risk-taking behavior, no significant impairment was found in any group.
    Limitations: As sample size was limited, it is possible that differences between BD and MDD may have escaped detection due to lack of statistical power.
    Conclusions: Our findings show that alterations of cognitive domains-while present in both disorders-are differently associated with BD and MDD. This underscores the importance of assessing such domains in addition to mere diagnosis of mood disorders.

    Abstract Neurotransmitter receptors are key molecules in signal transmission, their alterations are associated with brain dysfunction. Relationships between receptors and their corresponding genes are poorly understood, especially in humans. We combined in vitro receptor autoradiography and RNA sequencing to quantify, in the same tissue samples (7 subjects), the densities of 14 receptors and expression levels of their corresponding 43 genes in the Cornu Ammonis (CA) and dentate gyrus (DG) of human hippocampus. Significant differences in receptor densities between both structures were found only for metabotropic receptors, whereas significant differences in RNA expression levels mostly pertained ionotropic receptors. Receptor fingerprints of CA and DG differ in shapes but have similar sizes; the opposite holds true for their "RNA fingerprints", which represent the expression levels of multiple genes in a single area. In addition, the correlation coefficients between receptor densities and corresponding gene expression levels vary widely and the mean correlation strength was weak-to-moderate. Our results suggest that receptor densities are not only controlled by corresponding RNA expression levels, but also by multiple regionally specific post-translational factors.

    Title translation Breakthrough in understanding the molecular causes of psychiatric disorders
    Abstract Ein Beitrag genetischer Faktoren zur Entwicklung psychiatrischer Krankheiten wie den häufigen schizophrenen und affektiven Störungen war lange vermutet worden, deren zuverlässige molekulare Identifizierung gelingt aber erst seit wenigen Jahren. Möglich wurde dies durch technologische Fortschritte in der Charakterisierung der individuellen Ausprägungen des menschlichen Genoms und durch Zusammenführung großer genetischer Datensätze auf internationaler Ebene. Die Ergebnisse der genomweiten Analysen erlauben erstmals einen systematischen Einblick in krankheitsrelevante biologische Mechanismen, die integrierte Betrachtung unterschiedlicher Omiks-Ebenen trägt dabei wesentlich zur funktionellen Interpretation der genetischen Befunde bei. Die Ergebnisse der genetischen Untersuchungen zeigen auch, wie stark die Ätiologien unterschiedlicher psychiatrischer Krankheiten überlappen, mit den größten G emeinsamkeiten zwischen schizophrenen und bipolar affektiven Störungen. Das Ziel der Translation genetischer Befunde in die klinische Praxis wird auf unterschiedlichen Ebenen verfolgt, in der Regel sind aber aufwendige Folgestudien notwendig. Die diagnostische Untersuchung seltener genomischer Deletionen/Duplikationen (sog. Kopienzahlvarianten) bei Patienten mit Schizophrenie wird wahrscheinlich eines der ersten Beispiele klinischer Anwendung sein, hierfür werden derzeit die notwendigen Voraussetzungen definiert.
