[Influence of guideline recommendations, care structures and individual factors on the use of psychosocial therapies in severely mentally ill people]. / Einfluss von Leitlinienempfehlungen, Versorgungsstrukturen und individuellen Faktoren auf die Inanspruchnahme von psychosozialen Therapien bei schwer psychisch kranken Menschen.

OBJECTIVE: The influence of guideline recommendations and other factors on the utilization of psychosocial interventions in people with severe mental illness was examined. METHODS: Data from a cross-sectional study of 397 people with severe mental illness were analysed descriptively. RESULTS: Patients are less likely to receive therapies with a strong recommendation compared to other levels of recommendation. Various other factors are diffusely associated with utilization rates, but no ubiquitous predictors could be identified across all therapies. CONCLUSION: Current practice in the use of psychosocial interventions does not follow guideline recommendation strength. Interventions with strong recommendations are probably not available across services. Consequently, routine practice is not able to follow guideline recommendations according to their strength. Other consistent predictors could not be identified.

The transformation of masculinity orientations and work-related attitudes in men treated for depression (TRANSMODE): study protocol for a mixed-methods observational study.

BACKGROUND: Masculinity norms play a crucial role in men's help-seeking behaviors, service-use, and coping strategies for depression. While previous studies provided evidence for the association between gender role orientations, work related attitudes, stigmatization of men with depression and depressive symptoms, it remains unclear to what extent gender role orientations change over time and whether psychiatric and psychotherapeutic treatment have an impact on these transformations. Additionally, the role of partners in supporting depressed men and the impact of dyadic coping on these processes have not been explored. The aim of this study is to investigate how masculinity orientations and work-related attitudes change over time in men treated for depression, and to examine the role of their partners and dyadic coping in these transformation processes. METHODS: TRANSMODE is a prospective longitudinal mixed-methods study investigating the transformation of masculinity orientations and work-related attitudes in men treated for depression between the ages of 18 and 65 from different settings in Germany. The study will recruit 350 men from various settings for quantitative analysis. By applying a latent transition analysis, the primary outcome are changes in masculine orientations and work-related attitudes over time, measured at four times (t0, t1, t2, t3) with intervals of 6 months. Qualitative interview with a subsample of depressed men selected using latent profile analysis, will be conducted between t0 and t1 (a1) with a follow-up of 12 months (a2). In addition, qualitative interviews with the partners of depressed men will be conducted between t2 and t3 (p1). Qualitative data will be analysed using qualitative structured content analysis. DISCUSSION: A comprehensive understanding of the transformation processes of masculinity orientations over time including the impact of psychiatric/psychotherapeutic treatment and the role of partners can lead to the development of gender-sensitive depression treatment tailored to the unique needs of men with depression. Thus, the study can promote more effective and successful treatment outcomes and further contribute to reducing the stigma surrounding mental health issues among men and encourage them for mental health service use. TRIAL REGISTRATION: This study is registered in the German Clinical Trail Register (DRKS) and the WHO International Clinical Trials Registry Platform (ICTRP) under registration number DRKS00031065 (Date of registration 06 February 2023).

[Patient Preferences for Exercise Therapy in People with Severe Mental Illness in Germany]. / Der subjektive Stellenwert von Bewegungs- und Sporttherapie bei Menschen mit schwerer psychischer Erkrankung in Deutschland.

PURPOSE: Assessing the experience with and the attitudes towards exercise therapy in persons with severe mental illness (SMI). Furthermore, potential variables of high preference towards exercise therapy are investigated. METHODS: Cross-sectional observational study of SMI patients aged between 18 and 65 years (n=385). Patients were interviewed by trained staff using standardised instruments. Potential variables were analysed using a hierarchic binary logistic regression model. RESULTS: 84,4% of SMI patients had a high preference for exercise therapy; of these, 44,1% exercised regularly. Among patients with severe mental illness especially a higher value in the GAF-assessment (p=0,041) and living in a metropolitan area (p=0,011) predict a high preference for exercise therapy. CONCLUSION: Most of the patients with severe mental illness interviewed in this study place a surprisingly high value on sports and exercise therapy. Due to the increasing evidence with regard to positive effects of these therapies, it may be an excellent starting point to expand sports and exercise therapy as part of a comprehensive treatment plan. At the same time, strategies for everyday transfer need to be implemented more rigorously.

Study protocol of a randomized controlled trial evaluating home treatment with peer support for acute mental health crises (HoPe).

BACKGROUND: Home treatment (HT) is a treatment modality for patients with severe mental illness (SMI) in acute mental crises. It is frequently considered equivalent to psychiatric inpatient treatment in terms of treatment outcome. Peer Support (PS) means that people with lived experience of a mental illness are trained to support others on their way towards recovery. While PS is growing in international importance and despite a growing number of studies supporting its benefits, it is still not comprehensively implemented into routine care. The HoPe (Home Treatment with Peer Support) study investigates a combination of both - HT and PS - to provide further evidence for a recovery-oriented treatment of psychiatric patients. METHODS: In our randomized controlled trial (RCT), HT with PS is compared with HT without PS within a network of eight psychiatric clinical centers from the North, South and East of Germany. We investigate the effects of a combination of both approaches with respect to the prevention of relapse/recurrence defined as first hospitalization after randomization (primary outcome), disease severity, general functioning, self-efficacy, psychosocial health, stigma resistance, recovery support, and service satisfaction (secondary outcomes). A sample of 286 patients will be assessed at baseline after admission to HT care (data point t0) and randomized into the intervention (HT + PS) and control arm (HT). Follow-Up assessments will be conducted 2, 6 and 12 months after admission (resulting in three further data points, t1 to t3) and will be analyzed via intention-to-treat approach. DISCUSSION: This study may determine the positive effects of PS added to HT, prove additional evidence for the efficacy of PS and thereby facilitate its further implementation into psychiatric settings. The aim is to improve quality of mental health care and patients' recovery as well as to reduce the risk of relapses and hospitalizations for patients with SMI. TRIAL REGISTRATION: The trial is registered with ClinicalTrials.gov: NCT04336527 , April 7, 2020.

The role of migration in mental healthcare: treatment satisfaction and utilization.

Migration rates increase globally and require an adaption of national mental health services to the needs of persons with migration background. Therefore, we aimed to identify differences between persons with and without migratory background regarding (1) treatment satisfaction, (2) needed and received mental healthcare and (3) utilization of mental healthcare.In the context of a cross-sectional multicenter study, inpatients and day hospital patients of psychiatric settings in Southern Germany with severe affective and non-affective psychoses were included. Patients' satisfaction with and their use of mental healthcare services were assessed by VSSS-54 and CSSRI-EU; patients' needs were measured via CAN-EU.In total, 387 participants (migratory background: n = 72; 19%) provided sufficient responses for analyses. Migrant patients were more satisfied with the overall treatment in the past year compared to non-migrant patients. No differences between both groups were identified in met and unmet treatment needs and use of supply services (psychiatric, psychotherapeutic, and psychosocial treatment).Despite a comparable degree of met and unmet treatment needs and mental health service use among migrants and non-migrants, patients with migration background showed higher overall treatment satisfaction compared to non-migrants. The role of sociocultural and migrant-related factors may explain our findings.

Predictors of competitive employment in individuals with severe mental illness: results from an observational, cross-sectional study in Germany.

BACKGROUND: Employment is of great importance as it is associated with various positive effects. Individuals with severe mental illness (SMI) are often excluded from competitive employment. Current data on employment of individuals with mental illness are rare, and influencing factors are under-researched. The present study examines possible predictors of competitive employment among individuals with SMI. METHODS: This was a cross-sectional and multicentered study of 300 individuals with SMI aged 18 to 65 years. The following inclusion criteria were used: (I) diagnosis of schizophrenia, schizotypal and delusional disorders (ICD-10 F2x), or affective disorders (ICD-10 F3x), (II) duration of psychiatric illness ≥ 2 years, and (III) substantial impact of illness on social functioning. Participants were interviewed by trained staff using standardised instruments. The relationship between potential predictors (age, sex, education, marital status, living situation, migration background, psychosocial functioning, age at first mental problem, physical illness, work ability) and employment was analysed using a hierarchic binary logistic regression model. RESULTS: Only one-third (34%) of participants were competitively employed. Almost one-third were unemployed (30%), and 28% reported early retirement due to mental illness. Psychosocial functioning was positively associated with competitive employment (OR = 1.09, 95% CI: 1.05 - 1.13, p < 0.001); concurrent chronic physical illness was negatively associated with competitive employment (OR = 0.38, 95% CI: 0.21 - 0.71, p = 0.002). CONCLUSIONS: Findings confirm a high risk of exclusion from competitive employment among individuals with SMI. Nonetheless, a substantial proportion of individuals are employed. Findings call for efforts to maintain or enhance workforce participation among individuals with SMI. A special focus should be placed on improving physical health and strengthening psychosocial functioning. TRIAL REGISTRATION: The study was registered in the German Clinical Trials Register (DRKS) under the registration number DRKS00015801 before the start of recruitment (Registration date: 21.02.2019).

[Peer Support: Utilization and Benefit in Severe Mental Illness - Results from an Observational, Cross-Sectional Study]. / Genesungsbegleitung: Inanspruchnahme und Nutzenbewertung aus Betroffenenperspektive ­ Ergebnisse einer Beobachtungsstudie.

OBJECTIVE: Peer support is playing an increasing role in the treatment of severely mentally ill people. International findings are available on its effectiveness. However, little is known about knowledge, use and benefit assessment in Germany. This paper addresses this question and presents results from an observational study with 10 participating clinics in southern Germany. METHODS: As part of the observational cross-sectional study with people with severe mental illness (IMPPETUS, N=359), sociodemographic and illness- and treatment-associated data were collected by trained study staff between March 2019 and September 2019. Binary logistic regression was used to analyse a possible association with peer support use. RESULTS: 38% (N=138) of respondents reported knowledge about the possibility of peer support; 15% (N=55) affirmed its use. Use of peer support varied across sites (between 6.5 and 37.5%) and was associated with household income. Significantly less frequent use of peer support was among those with high versus low household income (OR=0.20 [95% CI: 0.06-0.68], p=0.01). Of respondents with peer support use (N=55), 78% reported perceiving peer support to be helpful or highly helpful. DISCUSSION: Peer support not only proves to be effective under study conditions with regard to various outcomes, but is also assessed as beneficial under routine conditions in a defined care region by the majority of users. However, only a few respondents knew and used the possibility of peer support. CONCLUSION: In order to implement peer support more strongly, information about this kind of service should be provided more effectively and a dialogue about successful implementation experiences should be initiated on a regional level.

Employment status and desire for work in severe mental illness: results from an observational, cross-sectional study.

PURPOSE: People with a severe mental illness (SMI) are at particular risk of occupational exclusion. Among the approaches to occupational rehabilitation, supported employment (SE) has been proven to be the most effective. A requirement to enter SE-programs is that individuals must want to seek competitive employment. The aim of this work is to investigate the relationship between serious mental illness and the desire to work including potential predictors. METHODS: This is a cross-sectional observational study of patients with SMI aged 18-65 years (n = 397). Patients were interviewed by trained staff using standardised instruments. The relationship between potential predictors and a strong preference for employment were analysed using a hierarchic binary logistic regression model. RESULTS: Only about one-quarter (27.9%) of SMI patients is in competitive employment. Another quarter is unemployed (25.9%). Results show that the desire for competitive employment is strong among more than half of the SMI patients. Among the unemployed, two-thirds express a strong desire for work. These individuals are an ideal target group for SE interventions. Comorbid chronic physical illness, diagnosis, and the subjectively judged ability to work are associated with the desire for work. CONCLUSION: Our data confirm a substantial exclusion of individuals with SMI from the workforce. In general, care needs for workplace interventions are not being met and leave much room for improvement. In addition to employment status, the desire for work should be routinely assessed. STUDY REGISTRATION: The study was registered in the German Clinical Trials Register (DRKS) ( https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00015801 ) and under the WHO-Platform "International Clinical Trials Registry Platform" (ICTRP) ( https://apps.who.int/trialsearch/Trial2.aspx?TrialID=DRKS00015801 ) under the registration number DRKS00015801 before the start of recruitment (Registration date: 21.02.2019).

[Men with Depression and Inpatient Mental Health Treatment: Professionals' Perspectives on Treatment Needs and Aims]. / Männer mit depressiven Erkrankungen in der stationären Behandlung: Bedarf und Behandlungsziele aus Sicht psychiatrischer Fachkräfte.

OBJECTIVE: To meet mental health needs in men with depression, gender sensitive services are needed and recommended. Therefore, mental health professionals' views on care needs among men with depression that should be met by gender-sensitive services were assessed and consequences for inpatient treatment are considered. METHODS: Semi-structured interviews were conducted with 33 mental health professionals focusing on men's specific needs in depression treatment against the background of male gender role expectations. Qualitative Content Analysis was performed using MAXqda-Software. RESULTS: Men with depression benefit from individual talk with staff and structured activity during treatment. Men-only groups are assessed as enabling critical reflection of aspects of masculinity. Physical activities and handicraft enable men to examine their performance level. Services focusing on men's specific needs are assessed as helpful but largely inexistent. CONCLUSION: Expectations of social gender roles and their implications for mental health treatment should be considered in both mental health professional training and mental health treatment.

Masculinity and Help-Seeking Among Men With Depression: A Qualitative Study.

Background: Many studies indicate that men are more reluctant to seek help for mental health problems than women. Traditional ideas of masculinity are often seen as a cause of this phenomenon. However, little is known about the diversity of experiences during the processes of help-seeking and service use among men with depression who have already utilized mental health services. This study aims to explore men's experiences and attitudes toward depression, help-seeking, and service use in order to develop gender-sensitive services. Methods: Narrative-biographical interviews were conducted with men treated for depression (n = 12). Interview topics included individual experience with depression, help-seeking behavior, and mental health service use. Transcripts were analyzed using qualitative content analysis. Results: Before seeking treatment, men's help-seeking behavior was negatively affected by internalized masculine norms. However, findings indicate a change of attitudes toward depression after mental health service use. Men with depression emphasized a salutogenic perspective toward mental health problems and critically reflected on masculine norms. The positive function of men-only groups were described as key for successful service use. Conclusions: Men with depression reported experiences toward help-seeking and service use on four different levels: (i) attitudes toward depression, (ii) perception of societal views on depression, (iii) experiences within the family context and (iv) experiences with mental health services. Interventions to reduce the stigma of being "unmanly" and to improve men's capacity to cope with being unable to work should be developed. Peer-led men-only groups may increase participants' self-esteem and assist in disclosing weaknesses. In the context of GPs' mediating role, training for health professionals concerning the impact of masculine norms on mental health is recommended.

Mental health professionals view about the impact of male gender for the treatment of men with depression - a qualitative study.

BACKGROUND: The underestimation of depression among men may result from atypical depression symptoms and male help-seeking behaviour. However, higher suicide rates among men than among women indicate a need for gender-specific services for men with depression. In order to develop gender-specific services, it is essential to examine professionals' attitudes towards men's depressive symptoms and treatment needs as well as barriers to and facilitators of treatment. This study examined gender-specific treatment needs in male patients and treatment approaches to male patients from a professional perspective. METHODS: Semi-structured face-to-face interviews were conducted with 33 mental health professionals (MHPs) from five German psychiatric institutions. The study assessed the characteristics and attributes of male patients with depression risk factors for the development of depression among men, their condition at the beginning of treatment, male patients' depressive symptoms, the needs and expectations of male patients, the importance of social networks in a mental health context, and MHPs' treatment aims and treatment methods. Transcripts were analysed using qualitative content analysis. RESULTS: The professionals' reference group of male patients were men who were characterised in accordance with traditional masculinity. Attributes reported as in line with this type of men were late initiations of inpatient treatment after crisis, suicidal ideation or attempted suicide, and high expectations towards treatment duration, success rate in recovery and therapeutic sessions. In contrast, male patients who deviate from these patterns were partially described with reference to female stereotypes. Professionals referred to psychosocial models in their explanations of the causes of depression and provided sociological explanations for the development of masculine ideals among men. The consequences of these for treatment were discussed against the background of normative expectations regarding the male gender. From the professionals' point of view, psychoeducation and the acceptance of depression (as a widespread mental illness) were the most important goals in mental health treatment. CONCLUSIONS: In order to improve mental health among men, gender-specific services should be offered. Awareness of the role of gender and its implications on mental health treatment should be an integral part of MHPs' education and their daily implementation of mental health treatment practices.

Functional Decoupling of Language and Self-Reference Networks in Patients with Persistent Auditory Verbal Hallucinations.

BACKGROUND: Accumulating neuroimaging evidence suggests that abnormal intrinsic neural activity could underlie auditory verbal hallucinations (AVH) in patients with schizophrenia. However, little is known about the functional interplay between distinct intrinsic neural networks and their association with AVH. METHODS: We investigated functional network connectivity (FNC) of distinct resting-state networks as well as the relationship between FNC strength and AVH symptom severity. Resting-state functional MRI data at 3 T were obtained for 14 healthy controls and 10 patients with schizophrenia presenting with persistent AVH. The data were analyzed using a spatial group independent component analysis, followed by constrained maximal lag correlations to determine FNC within and between groups. RESULTS: Four components of interest, comprising language, attention, executive control networks, as well as the default-mode network (DMN), were selected for subsequent FNC analyses. Patients with persistent AVH showed lower FNC between the language network and the DMN (p < 0.05, corrected for false discovery rate). FNC strength, however, was not significantly related to symptom severity, as measured by the Psychotic Symptom Rating Scale. CONCLUSION: These findings suggest that disrupted FNC between a speech-related system and a network subserving self-referential processing is associated with AVH. The data are consistent with a model of disrupted self-attribution of speech generation and perception.

Masculinity norms and occupational role orientations in men treated for depression.

PURPOSE: A traditional male role orientation is considered to increase the risk of depression and preventing men from disclosing symptoms of mental illness and seeking professional help. Less is known about the variance of masculinity orientations in men already treated for depression and their role in the treatment process. In this study, patterns of masculinity norms and work role orientations will be identified among men treated for depression. Associations of these patterns with depressive symptoms, stigma and delay in professional help-seeking will be investigated. METHODS: In a cross-sectional study, male role orientations (MRNS), work-related attitudes (AVEM), symptoms of mental disorders (PHQ), and attitudes related to stigma of mental illness (DSS) were assessed by standardized methods in a sample of 250 men treated for depression in general medical, psychiatric and psychotherapeutic services. Data were analyzed by means of latent profile analysis (LPA), by multinomial and linear regression models, and by path analysis. RESULTS: The results of LPA revealed three latent classes of men treated for depression. Men assigned to class one reported a less traditional male role orientation, low professional ambitions and low coping capacities; men assigned to class two reported a traditional masculinity orientation, high professional ambitions but low coping capacities; men assigned to class three reported less traditional masculinity tended orientations, medium professional ambitions and high coping capacities. Men assigned to classes one and two to have more stigmatizing attitudes, longer periods of untreated illness and more severe symptoms of mental disorders, in comparison to men assigned to class three. CONCLUSIONS: Overall, this study reveals that traditional masculinity norms and work-role orientations in men treated for depression are associated with a worse mental health status. Our study results also suggest that a slackening of traditional masculinity norms is associated with improved psychological well-being if it does not coincide with a complete distancing from professional ambitions and a lack of ability to cope with professional stress.

Implementation of the patient version of the evidence-based (S3) guideline for psychosocial interventions for patients with severe mental illness (IMPPETUS): study protocol for a cluster randomised controlled trial.

BACKGROUND: The German guideline on psychosocial interventions for people with severe mental disorders recommends a broad spectrum of evidence-based treatments. Structured implementation of the associated patient version of the guideline is missing to date. The study aims to assess whether structured implementation of a patient guideline improves the empowerment of patients with severe mental disorders, as well as knowledge, attitudes and experiences regarding psychosocial interventions, service use, treatment satisfaction, treatment needs, quality of life and burden of care. METHODS: The study is a multicentre, cluster-randomised, controlled study with two parallel groups. Inpatients and day hospital patients (all sexes; 18-65 years) with severe mental disorders will be included. Additionally, relatives of patients with mental disorders (all sexes; ≥ 18 years) will be included. In the experimental group, the patient guideline will be implemented using a multimodal strategy. Participants in the control group will receive treatment as usual but will be made aware of the patient guideline. The primary outcome is the change of empowerment, assessed by using the 'empowerment in the process of psychiatric treatment of patients with affective and schizophrenia disorders' (EPAS) scale. In addition, knowledge, attitudes and experiences regarding psychosocial interventions will be assessed as secondary outcomes, as well as service use, satisfaction with care, patient need and quality of life and participation and social inclusion. For relatives, the perceived burden of care also will be recorded. Results will be analysed using hierarchical linear models. For the health economic evaluation, the incremental cost-utility ratios will be computed using the differences in total costs of illness and the differences in quality-adjusted life years (QALY) between study groups. DISCUSSION: The study will be the first to assess the effects of a structured implementation of the patient version of a psychiatric treatment guideline. The study has some limitations regarding the transferability of the results to other patients and other regions. Furthermore, problems with the recruitment of patients and relatives and with the implementation of intervention could occur during the study. TRIAL REGISTRATION: The study is registered in the German Clinical Trials Register (DRKS) and the WHO International Clinical Trials Registry Platform (ICTRP) under registration number DRKS00017577 (Date of registration: 23 October 2019.

[Men and Depression: Illness Theories and Coping - A Biographical Narrative Study]. / Depression und Männlichkeit: Krankheitstheorien und Bewältigung ­ Eine biografisch-narrative Studie.

OBJECTIVE: In order to develop gender-sensitive services, there is a need to better understand coping among men with depression. The study aims to analyze the meaning of gender- and work-related roles for illness theories and coping among men with depression. METHODS: Based on a latent class analysis of three types of masculinities, biographical interviews were conducted with men with depression (n = 12). Transcripts were analyzed using a hermeneutic-reconstructive approach that includes subjective constructions of meaning related to (1) illness theories, (2) coping and (3) help-seeking behavior. RESULTS: Whereas most interviewees reported the role of family-related career orientation as a cause of depression, results differ in terms of coping. While participants partly distanced themselves from external expectations, some tried to keep up their employability. Others perceived their depression as a chance as well as an opportunity to change harmful attitudes. CONCLUSION: Psychiatric services might consider different priorities referring to work and life and their impact on coping with depression among men.

[Empowerment and Stigma as Mediator Variables Between Illness Severity and Quality of Life of Patients with Affective Disorders]. / Empowerment und Stigma als Mediatorvariablen zwischen Krankheitsschwere und Lebensqualität bei Patienten mit einer affektiven Erkrankung.

OBJECTIVE: The investigation of mediating effects of empowerment and stigmatization on the association between depressive symptoms and subjective quality of life in patients with affective disorders. METHOD: Depressive Symptoms (BDI-II), internalized and perceived stigmatization (ISMI; PDDQ), empowerment (EPAS) and subjective quality of life (WHOQOL-BREF) were assessed in 37 patients with affective disorders (F31 - F33; ICD-10), age 18+ in inpatient, day hospital or outpatient psychiatric treatment. Data analyses were conducted by means of path-analysis. RESULTS: Empowerment and in low proportion internalized and perceived stigma turned out to be mediating variables between the severity of depression and subjective quality of life. 57 % of the variance of the subjective quality of life could be explained by the path model. CONCLUSION: Empowerment has meaningful influence mediating between depression and subjective quality of life. In order to improve the quality of life of patients with an affective disorder, strategies for increasing empowerment are to be integrated into treatment.

A cross-continental analysis of weight gain, psychiatric diagnoses and medication use during inpatient psychiatric treatment. The international study on physical illness in mentally ill.

Weight gain among psychiatric inpatients is a widespread phenomenon. This change in body mass index (BMI) can be caused by several factors. Based on recent research, we assume the following factors are related to weight gain during psychiatric inpatient treatment: psychiatric medication, psychiatric diagnosis, sex, age, weight on admission and geographic region of treatment. 876 of originally recruited 2328 patients met the criteria for our analysis. Patients were recruited and examined in mental health care centres in Nigeria (N = 265), Japan (N = 145) and Western-Europe (Denmark, Germany and Switzerland; N = 466). There was a significant effect of psychiatric medication, psychiatric diagnoses and geographic region, but not age and sex, on BMI changes. Geographic region had a significant effect on BMI change, with Nigerian patients gaining significantly more weight than Japanese and Western European patients. Moreover, geographic region influenced the type of psychiatric medication prescribed and the psychiatric diagnoses. The diagnoses and psychiatric medication prescribed had a significant effect on BMI change. In conclusion, we consider weight gain as a multifactorial phenomenon that is influenced by several factors. One can discuss a number of explanations for our findings, such as different clinical practices in the geographical regions (prescribing or admission strategies and access-to-care aspects), as well as socio-economic and cultural differences.

Cortical folding abnormalities in patients with schizophrenia who have persistent auditory verbal hallucinations.

In schizophrenia temporal cortical volume loss differs between patients presenting with persistent auditory verbal hallucinations (pAVH) in contrast to those without hallucinatory symptoms (nAVH). However, it is unknown whether this deficit reflects a neural signature of neurodevelopmental origin or if abnormal temporal cortical volume is reflective of factors which may be relevant at later stages of the disorder. Here, we tested the hypothesis that local gyrification index (LGI) in regions of the temporal cortex differs between patients with pAVH (n=10) and healthy controls (n=14), and that abnormal temporal LGI discriminates between pAVH and nAVH (n=10). Structural magnetic resonance imaging at 3T along with surface-based data analysis methods was used. Contrary to our expectations, patients with pAVH showed lower LGI in Broca´s region compared to both healthy persons and nAVH. Compared to nAVH, those individuals presenting with pAVH also showed lower LGI in right Broca's homologue and right superior middle frontal cortex, together with increased LGI in the precuneus and superior parietal cortex. Regions with abnormal LGI common to both patient samples were found in anterior cingulate and superior frontal areas. Inferior cortical regions exhibiting abnormal LGI in pAVH patients were associated with overall symptom load (BPRS), but not with measures of AVH symptom severity. The pattern of abnormal cortical folding in this sample suggests a neurodevelopmental signature in Broca's region, consistent with current AVH models emphasizing the pivotal role of language circuits and inner speech. Temporal cortical deficits may characterize patients with pAVH during later stages of the disorder.

Cerebellar Contributions to Persistent Auditory Verbal Hallucinations in Patients with Schizophrenia.

There is growing evidence that the cerebellum plays a crucial role in the pathophysiology of schizophrenia symptoms. Despite increasing evidence for cerebellar involvement in affective, attentive, and cognitive functions including language processing and perception, investigations of cerebellar contributions to auditory verbal hallucinations (AVH) in schizophrenia are lacking. Using structural magnetic resonance imaging at 3T, we investigated the data of 20 patients with schizophrenia and 14 matched healthy controls. Ten patients were classified as having chronic and treatment resistant AVH (pAVH), whereas the remaining ten patients either never had AVH in the past or were in full remission with regard to AVH (nAVH). Employing cerebellum-optimized segmentation techniques, i.e., the Spatially Unbiased Infratentorial Template (SUIT) toolbox, we investigated cerebellar gray matter volume (GMV) differences among the pAVH, nAVH, and a healthy control group, the magnitude of their expression between these groups and the relationship between GMV and schizophrenia symptom load. Lower GMV in pAVH patients compared to controls was found in lobules VIIb and VIIIa. Additionally, lower GMV in pAVH compared to nAVH patients was found in lobule VIIIa. A negative relationship between VIIIa GMV and overall positive symptoms was detected. Correlations with AVH-specific psychometric scores were not significant. This study shows that there are structural changes in the cognitive regions of the cerebellum that are linked to a clinical phenotype presenting with persistent positive symptoms such as AVH. The results suggest that the cerebellum and its associated neural circuits do play a role in the emergence of positive symptoms in schizophrenia, but probably not exclusively in AVH symptom expression.
