The German research consortium for the study of bipolar disorder (BipoLife): a quality assurance protocol for MR neuroimaging data.

Background: The German multicenter research consortium BipoLife aims to investigate the mechanisms underlying bipolar disorders. It focuses in particular on people at high risk of developing the disorder and young patients in the early stages of the disease. Functional and structural magnetic resonance imaging (MRI) data was collected in all participating centers.

Effects of high-intensity interval training on sleep disturbances associated with posttraumatic stress disorder.

Sleep disturbances are common in individuals with posttraumatic stress disorder. Exercise interventions are a promising approach in the treatment of sleep disorders, but little is known about the efficacy of exercise interventions for sleep disturbances associated with posttraumatic stress disorder. A total of 40 individuals with posttraumatic stress disorder were randomized to six sessions of either high-intensity interval training or low-to-moderate-intensity training, administered within 12 days.

Level of structural integration in people with schizophrenia and schizoaffective disorders - applicability and associations with clinical parameters.

Introduction: The psychic structure of people with psychosis has been the subject of theoretical and qualitative considerations. However, it has not been sufficiently studied quantitatively. Therefore, the aim of this study was to explore the structural abilities of people diagnosed with schizophrenia and schizoaffective psychosis using the Levels of Structural Integration Axis of the Operationalized Psychodynamic Diagnosis System (OPD-2-LSIA).

Larger putamen in individuals at risk and with manifest bipolar disorder.

Background: Individuals at risk for bipolar disorder (BD) have a wide range of genetic and non-genetic risk factors, like a positive family history of BD or (sub)threshold affective symptoms. Yet, it is unclear whether these individuals at risk and those diagnosed with BD share similar gray matter brain alterations.

Methods: In 410 male and female participants aged 17-35 years, we compared gray matter volume (3T MRI) between individuals at risk for BD (as assessed using the EPI scale; = 208), patients with a DSM-IV-TR diagnosis of BD ( = 87), and healthy controls ( = 115) using voxel-based morphometry in SPM12/CAT12.

What to think or how to think - is symptom reduction in posttraumatic symptomatology associated with change in posttraumatic cognitions or perseverative thinking? A latent change score model approach.

Objective: Patients with posttraumatic stress disorder (PTSD) report changes in they think of the world and themselves, referred to as posttraumatic cognitions, and changes in they think, reflected in increased perseverative thinking. We investigated whether pre-post therapy changes in the two aspects of thinking were associated with pre-post therapy changes in posttraumatic symptom severity.

Method: 219 d clinic patients with posttraumatic stress symptoms received trauma-focused psychotherapy with cognitive behavioral and metacognitive elements.

Psychiatric and non-psychiatric patients during the midst of Covid-19: Pandemic distress, psychosis and the belief in conspiracy theories.

Background: The COVID-19 pandemic was associated with increased levels of psychological distress in the general population, at the same time providing a perfect breeding ground for conspiracy beliefs. Psychiatric patients are considered as a population with an increased vulnerability for stressful events, and conspiracy beliefs show overlaps with paranoid ideations. The aim of the present study was to investigate if psychiatric patients experienced higher levels of pandemic distress than non-psychiatric patients, if they were more prone to conspiracy beliefs and if pandemic distress as well as other mental health variables were associated with believing in conspiracy theories.

The mediating role of attachment and anger: exploring the impact of maternal early-life maltreatment on child abuse potential.

Background: Maternal early-life maltreatment (ELM) increases the risk of subsequent child maltreatment, but the underlying mechanisms of these intergenerational effects remain largely unknown. Identifying these mechanisms is crucial for developing preventive interventions that can break the cycle of abuse. Notably, previous research has shown that ELM often results in attachment insecurity and altered anger characteristics.

Young people at risk for developing bipolar disorder: Two-year findings from the multicenter prospective, naturalistic Early-BipoLife study.

Early identification and intervention of individuals with an increased risk for bipolar disorder (BD) may improve the course of illness and prevent long‑term consequences. Early-BipoLife, a multicenter, prospective, naturalistic study, examined risk factors of BD beyond family history in participants aged 15-35 years. At baseline, positively screened help-seeking participants (screenBD at-risk) were recruited at Early Detection Centers and in- and outpatient depression and attention-deficit/hyperactivity disorder (ADHD) settings, references (Ref) drawn from a representative cohort.

Increase in presentations with new-onset psychiatric disorders in a psychiatric emergency department in Berlin, Germany during the second wave of the COVID-19 pandemic - a retrospective cross-sectional study.

Introduction: While numerous studies have identified an increase in symptoms of depression as well as anxiety and distress due to the COVID-19 pandemic, relatively few studies have investigated the new-onset of psychiatric diseases during the pandemic.

Methods: This study focuses on the number of psychiatric new-onset diagnoses in a psychiatric emergency department (pED) in Berlin, Germany during the second wave of the pandemic (i.e.

Relationship between perceived coercion and perceived justification of coercive measures - secondary analysis of a randomized-controlled trial.

Background: Subjective perception of coercion has gained attention as an important outcome. However, little is known about its relation to patients' appraisal of the justification of coercive measures. The present study aims to analyze the relationship between patients' appraisal of the justification of coercive measures and their level of perceived coercion.

Affect Recognition, Theory of Mind, and Empathy in Preschool Children with Externalizing Behavior Problems-A Group Comparison and Developmental Psychological Consideration.

Preschool mental disorders are often associated with significant interpersonal problems, related to impaired affect recognition, theory of mind (ToM), and empathy. To date, these skills have not been studied together in preschoolers with externalizing behavior problems (EBPs). The aim of the present study was to investigate whether and to what extent preschool children with EBPs show impairments in affect recognition, ToM, and empathy.

Psychiatric Adverse Events of Acetylcholinesterase Inhibitors in Alzheimer's Disease and Parkinson's Dementia: Systematic Review and Meta-Analysis.

Background: The acetylcholinesterase inhibitors (AChEIs) donepezil, galantamine, and rivastigmine are commonly used in the management of various forms of dementia.

Objectives: While these drugs are known to induce classic cholinergic adverse events such as diarrhea, their potential to cause psychiatric adverse events has yet to be thoroughly examined.

Methods: We sought to determine the risk of psychiatric adverse events associated with the use of AChEIs through a systematic review and meta-analysis of double-blind randomized controlled trials involving patients with Alzheimer's dementia and Parkinson's dementia.

Validation of natural language processing methods capturing semantic incoherence in the speech of patients with non-affective psychosis.

Background: Impairments in speech production are a core symptom of non-affective psychosis (NAP). While traditional clinical ratings of patients' speech involve a subjective human factor, modern methods of natural language processing (NLP) promise an automatic and objective way of analyzing patients' speech. This study aimed to validate NLP methods for analyzing speech production in NAP patients.

Association of polygenic score and the involvement of cholinergic and glutamatergic pathways with lithium treatment response in patients with bipolar disorder.

Lithium is regarded as the first-line treatment for bipolar disorder (BD), a severe and disabling mental health disorder that affects about 1% of the population worldwide. Nevertheless, lithium is not consistently effective, with only 30% of patients showing a favorable response to treatment. To provide personalized treatment options for bipolar patients, it is essential to identify prediction biomarkers such as polygenic scores.

Coercive measures in psychiatry - When do they occur and who is at risk?

Coercive measures (CM) in psychiatry adversely affect patients and efforts to minimize CM are steadily increasing. One area that has not been a strong focus of preventative efforts to date is the time of use of CM during hospitalization although previous research indicates that the admission situation and early hospitalization are times of increased risk for CM. This study therefore aims to contribute to the body of research in this field by analyzing in detail the times of use of CM and identifying patient characteristics serving as predictors for CM during early hospitalization.

Prediction of estimated risk for bipolar disorder using machine learning and structural MRI features.

Background: Individuals with bipolar disorder are commonly correctly diagnosed a decade after symptom onset. Machine learning techniques may aid in early recognition and reduce the disease burden. As both individuals at risk and those with a manifest disease display structural brain markers, structural magnetic resonance imaging may provide relevant classification features.

Polygenetic risk scores and phenotypic constellations of obsessive-compulsive disorder in clozapine-treated schizophrenia.

Obsessive-compulsive symptoms (OCS) are frequently observed in individuals with schizophrenia (SCZ) treated with clozapine (CLZ). This study aimed to analyze prevalence of OCS and obsessive-compulsive disorder (OCD) in this subgroup and find possible correlations with different phenotypes. Additionally, this is the first study to examine polygenetic risk scores (PRS) in individuals with SCZ and OCS.

Daring to Feel: Emotion-Focused Psychotherapy Increases Amygdala Activation and Connectivity in Euthymic Bipolar Disorder-A Randomized Controlled Trial.

Background: In bipolar disorder (BD), the alternation of extreme mood states indicates deficits in emotion processing, accompanied by aberrant neural function of the emotion network. The present study investigated the effects of an emotion-centered psychotherapeutic intervention on amygdala responsivity and connectivity during emotional face processing in BD.

Methods: In a randomized controlled trial within the multicentric BipoLife project, euthymic patients with BD received one of two interventions over 6 months: an unstructured, emotion-focused intervention (FEST), where patients were guided to adequately perceive and label their emotions (n = 28), or a specific, structured, cognitive behavioral intervention (SEKT) (n = 31).

Leaving the stigma to the patients? Frequency of crisis experiences among mental health professionals in Berlin and Brandenburg and how they cope with it.

Background: Although mental health professionals' mental health problems are gaining increased attention, there is little systematic research on this topic.

Aims: This study investigated the frequency of crisis experiences among mental health professionals and examined how they approach these experiences in terms of their personal and social identities.

Methods: An online survey was conducted among mental health professionals in 18 psychiatric hospital departments in the German federal states of Berlin and Brandenburg ( = 215), containing questions about personal crisis experiences, help sought, service use, meaningfulness of lived experiences, causal beliefs of mental illness and psychotherapeutic orientation.

The Affect Intolerance Scale (AIS), German version: A validation study in a student and clinical sample of patients with trauma-related disorders.

Background And Objectives: The Affect Intolerance Scale (AIS) assesses two core concepts of emotion regulation: appraisals of negative emotions as threatening and proneness to emotional avoidance. Maladaptive emotion regulation is associated with various psychopathologies. We translated and validated the AIS in a German student and clinical sample of patients with trauma-related disorders.
