From a total of 18 submissions, nine articles were selected for publication. While this collection naturally cannot claim to be representative of the entire breadth of psychiatric research, these contributions strategically highlight key directions that have gained significant influence. Notably, the selected articles focus predominantly on psychosocial, systemic, and ethical dimensions, rather than biological or neuroscientific mechanisms. Together, they illustrate the wide spectrum of contemporary psychosocial themes in psychiatry, ranging from complex systemic interactions to rights-based frameworks, charting a course for future breakthroughs aimed at advancing mental wellbeing at both societal and individual levels.

Objectives Agomelatine, a melatonin (MT1/MT2) receptor agonist and 5-HT2C receptor antagonist, is a new antidepressant and a potential therapeutic option for major depressive episodes and negative symptoms in persons with schizophrenia. We investigated such treatment outcomes with respect to antidepressant efficacy, safety, and tolerability. Methods We report a consecutive case series of seven patients with schizophrenia and comorbid major depressive symptoms who received agomelatine for a period of at least six weeks in addition to stable doses of antipsychotic agents. General psychopathology, positive, negative and depressive symptoms were assessed with standardized interviews. Relevant blood parameters were assessed. Results Depressive symptoms improved significantly. Positive symptoms remained stable, while negative symptoms and global psychopathology improved significantly. Agomelatine was well tolerated in most patients. Conclusions Our findings provide initial evidence that agomelatine is safe and efficacious in treating depressive symptoms in patients with schizophrenia. Furthermore, agomelatine seems to be effective for the treatment of negative symptoms. Randomized controlled trials are necessary to confirm these first observations.

Background: Schizotypy represents an index of psychosis-proneness in the general population, often associated with childhood trauma exposure. Both schizotypy and childhood trauma are linked to structural brain alterations, and it is possible that trauma exposure moderates the extent of brain morphological differences associated with schizotypy.Methods: We addressed this question using data from a total of 1182 healthy adults (age range: 18–65 years old, 647 females/535 males), pooled from nine sites worldwide, contributing to the Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Schizotypy working group. All participants completed both the Schizotypal Personality Questionnaire Brief version (SPQ-B), and the Childhood Trauma Questionnaire (CTQ), and underwent a 3D T1-weighted brain MRI scan from which regional indices of subcortical gray matter volume and cortical thickness were determined.Results: A series of multiple linear regressions revealed that differences in cortical thickness in four regions-of-interest were significantly associated with interactions between schizotypy and trauma; subsequent moderation analyses indicated that increasing levels of schizotypy were associated with thicker left caudal anterior cingulate gyrus, right middle temporal gyrus and insula, and thinner left caudal middle frontal gyrus, in people exposed to higher (but not low or average) levels of childhood trauma. This was found in the context of morphological changes directly associated with increasing levels of schizotypy or increasing levels of childhood trauma exposure.Conclusions: These results suggest that alterations in brain regions critical for higher cognitive and integrative processes that are associated with schizotypy may be enhanced in individuals exposed to high levels of trauma.

Schizotypy represents an index of psychosis-proneness in the general population often associated with childhood trauma exposure. Both schizotypy and childhood trauma are linked to structural brain alterations, and it is possible that trauma exposure moderates the extent of brain morphological differences associated with schizotypy. We addressed this question using data from a total of 1,182 healthy adults (age range: 18-65 years old, 647 females/535 males), pooled from nine sites worldwide, contributing to the Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Schizotypy working group. All participants completed both the Schizotypal Personality Questionnaire Brief version (SPQ-B), and the Childhood Trauma Questionnaire (CTQ), and underwent a 3D T1-weighted brain MRI scan from which regional indices of subcortical grey matter volume and cortical thickness were determined. A series of multiple linear regressions revealed that differences in cortical thickness in four regions-of-interest were significantly associated with interactions between schizotypy and trauma; subsequent moderation analyses indicated that increasing levels of schizotypy were associated with thicker left caudal anterior cingulate gyrus, right middle temporal gyrus and insula, and thinner left caudal middle frontal gyrus, in people exposed to higher (but not low or average) levels of childhood trauma. This was found in the context of thicker bilateral medial orbitofrontal gyri, right rostral anterior cingulate gyrus, left temporal pole, left insula, and thinner left paracentral lobule directly associated with increasing levels of schizotypy. In addition, thinner left postcentral, superior parietal and lingual gyri, as well as thicker left caudal middle frontal gyrus and smaller left thalamus and right caudate were associated with increasing levels of childhood trauma exposure. These results suggest that alterations in brain regions critical for higher cognitive and integrative processes that are associated with schizotypy may be enhanced in individuals exposed to high levels of trauma.

In subjects at risk for psychosis, the studies on gray matter volume (GMV) predominantly reported volume loss compared with healthy controls (CON). However, other important morphological measurements such as cortical surface area (CSA) and cortical thickness (CT) were not systematically compared. So far, samples mostly comprised subjects at genetic risk or at clinical risk fulfilling an ultra-high risk (UHR) criterion. No studies comparing UHR subjects with at-risk subjects showing only basic symptoms (BS) investigated the differences in CSA or CT. Therefore, we aimed to unravel the contribution of the 2 morphometrical measures constituting the cortical volume (CV) and to test whether these groups inhere different morphometric features. We conducted a surface-based morphometric analysis in 34 CON, 46 BS, and 39 UHR to examine between-group differences in CV, CSA, and CT vertex-wise across the whole cortex. Compared with BS and CON, UHR individuals presented increased CV in frontal and parietal regions, which was driven by larger CSA. These groups did not differ in CT. Yet, at-risk subjects who later developed schizophrenia showed thinning in the occipital cortex. Furthermore, BS presented increased CSA compared with CON. Our results suggest that volumetric differences in UHR subjects are driven by CSA while CV loss in converters seems to be based on cortical thinning. We attribute the larger CSA in UHR to aberrant pruning representing a vulnerability to develop psychotic symptoms reflected in different levels of vulnerability for BS and UHR, and cortical thinning to a presumably stress-related cortical decomposition.

This study aims to analyze the relationship between the symptomatic dimensions of psychosis and functioning of individuals at risk for psychosis (ultrahigh risk [UHR]) in a non–help-seeking UHR sample from the general population. The sample is the same as the one used in the Brazilian Subclinical Symptoms and Prodromal Psychosis cohort study. We applied questionnaires of functioning (Global Assessment of Functioning Scale) and symptomatic dimensions (Scale of Prodromal Symptoms). Next, we correlated the symptomatic dimensions with functioning. We found a significant relationship between avolition and uncommon thought content with poor functioning, whereas the remaining symptoms were not as relevant. Poor functioning was most related to avolition, a negative symptom, followed by unusual thought content, a positive symptom.

Background: Access to a bank account is critical for overall participation in social life and an indicator for social integration. Worldwide about 1.7 billion people remain with no access to banking facilities as a form of financial exclusion which represents 31% of the world’s general population. In contrast, in Western countries like Germany, 99% of the general population use bank accounts. Methods: We conducted an exploratory cross-sectional survey on bank account ownership and bank account access among psychiatric in-patients in a psychiatric hospital in Berlin. Out of 540 participants who were reached for an interview, 486 shared information about bank account ownership and 469 on access. Results: Out of 486 participants 49 (10.1%) did not own a bank account. Among the remaining 420 participants owning a bank account, 36 (8.3%) did not have direct access to their bank account, but only, e.g., their legal guardian. Regression results found psychosis, intellectual disabilities, a longer treatment duration, as well as being of male gender and a more instable housing status to be significantly associated with a missing bank account or a missing access to one’s bank account. Conclusions: The lack of bank account ownership and access among this population of psychiatric patients is concerning. The interrelationship between factors of financial exclusion and mental health should be further explored in longitudinal studies. More attention is needed to support people with severe mental illness to be able to access resources associated with financial inclusion.
