Abstract Background Schizophrenia is the collective term for an exclusively clinically diagnosed, heterogeneous group of mental disorders with still obscure biological roots. Based on the assumption that valuable information about relevant genetic and environmental disease mechanisms can be obtained by association studies on patient cohorts of ≥ 1000 patients, if performed on detailed clinical datasets and quantifiable biological readouts, we generated a new schizophrenia data base, the GRAS (Göttingen Research Association for Schizophrenia) data collection. GRAS is the necessary ground to study genetic causes of the schizophrenic phenotype in a 'phenotype-based genetic association study' (PGAS). This approach is different from and complementary to the genome-wide association studies (GWAS) on schizophrenia. Methods For this purpose, 1085 patients were recruited between 2005 and 2010 by an invariable team of traveling investigators in a cross-sectional field study that comprised 23 German psychiatric hospitals. Additionally, chart records and discharge letters of all patients were collected. Results The corresponding dataset extracted and presented in form of an overview here, comprises biographic information, disease history, medication including side effects, and results of comprehensive cross-sectional psychopathological, neuropsychological, and neurological examinations. With >3000 data points per schizophrenic subject, this data base of living patients, who are also accessible for follow-up studies, provides a wide-ranging and standardized phenotype characterization of as yet unprecedented detail. Conclusions The GRAS data base will serve as prerequisite for PGAS, a novel approach to better understanding 'the schizophrenias' through exploring the contribution of genetic variation to the schizophrenic phenotypes.

Early exposure to negative environmental impact shapes individual behavior and potentially contributes to any mental disease. We reported previously that accumulated environmental risk markedly decreases age at schizophrenia onset. Follow-up of matched extreme group individuals (≤1 vs. ≥3 risks) unexpectedly revealed that high-risk subjects had >5 times greater probability of forensic hospitalization. In line with longstanding sociological theories, we hypothesized that risk accumulation before adulthood induces violent aggression and criminal conduct, independent of mental illness. We determined in 6 independent cohorts (4 schizophrenia and 2 general population samples) pre-adult risk exposure, comprising urbanicity, migration, physical and sexual abuse as primary, and cannabis or alcohol as secondary hits. All single hits by themselves were marginally associated with higher violent aggression. Most strikingly, however, their accumulation strongly predicted violent aggression (odds ratio 10.5). An epigenome-wide association scan to detect differential methylation of blood-derived DNA of selected extreme group individuals yielded overall negative results. Conversely, determination in peripheral blood mononuclear cells of histone-deacetylase1 mRNA as 'umbrella mediator' of epigenetic processes revealed an increase in the high-risk group, suggesting lasting epigenetic alterations. Together, we provide sound evidence of a disease-independent unfortunate relationship between well-defined pre-adult environmental hits and violent aggression, calling for more efficient prevention.

The correlation of formal thought disorder (FTD) symptoms and subsyndromes with neuropsychological dimensions is as yet unclear. Evidence for a dysexecutive syndrome and semantic access impairments has been discussed in positive FTD, albeit focusing mostly on patients with schizophrenia. We investigated the correlation of the full range of positive and negative as well as subjective and objective FTD with neuropsychological domains in different patient groups. Patients with ICD-10 schizophrenia (n = 51), depression (n = 51), and bipolar mania (n = 18), as well as healthy subjects (n = 60), were interviewed with the Rating Scale for the Assessment of Objective and Subjective Formal Thought and Language Disorder (TALD) and assessed using a multidimensional neuropsychological test battery (executive function, semantic and lexical verbal fluency, attention, working memory, and abstract thinking). Partial correlation analysis, controlling for age and word knowledge, revealed significant results for the objective positive FTD dimension and executive dysfunctions. Objective negative FTD was associated with deficits in lexico-semantic retrieval, as well as attention and working memory dysfunctions. The results suggest that different neuropsychological substrates correlate with the multidimensional and phenomenologically different FTD syndromes. FTD is a complex, multidimensional syndrome with a variety of neuropsychological impairments, which should be accounted for in future studies investigating the pathogenesis of FTD., (© 2016 S.

Formal thought disorder (FTD) is a core syndrome of schizophrenia. However, patients with other diagnoses, such as mania and depression amongst others, also present with FTD. We introduce a novel, comprehensive clinical rating scale, capturing the full variety of FTD phenomenology including subjective experiences. The 30-item Thought and Language Disorder (TALD) scale is based on a detailed review of the literature, encompassing all formal thought disorder symptoms reported from the early 20th century onwards. Objectively observable symptoms as well as subjective phenomena were included. Two hundred and ten participants (146 patients ICD-10 diagnoses: depression n=63, schizophrenia n=63, mania n=20; 64 healthy control subjects) were interviewed and symptoms rated with the TALD, TLC, HAMD, YMRS and SAPS/SANS. A principal component analyses was performed for the TALD to differentiate sub-syndromes. The principal component analysis revealed four FTD factors; objective and subjective as well as positive and negative factor dimensions. The correlation analyses with the TLC and the SAPS/SANS FTD sub-scores demonstrated the factor validity for the objective factors. The different diagnoses showed a distinct pattern of symptom severity in each of the factors, with mania patients exhibiting the highest value in the positive, objective dimension. The scale showed good psychometric results, which makes it a practicable, nosologically-open instrument for the detailed assessment of all FTD dimensions. The results strengthen the importance of subjective symptom assessment reported by the patient., (Copyright © 2014. Published by Elsevier B.V.)

The Scale for the Assessment of Thought, Language and Communication (TLC) represents an instrument for the assessment of formal thought disorder (FTD). The factorial dimensionality of the TLC has yielded ambiguous results for a distinction between positive (e.g. circumstantiality) and negative (e.g. poverty of speech) FTD. The purpose of the current study was to first translate and validate the TLC scale in German. Second, the internal structure was explored in order to identify different FTD dimensions. Two hundred and ten participants (146 patients with ICD-10 diagnoses: depression n = 63, schizophrenia n = 63, mania n = 20; 64 healthy subjects) were interviewed and FTD was rated with the TLC. The principal component analysis of the German TLC version revealed a 3-factor solution, reflecting a disorganized factor, an emptiness factor and a linguistic control factor. The current investigation yielded similar results to those originally reported for the TLC. Thus, a distinction between a positive disorganized, a negative and a semantic word level factor can be supported for the German translation., (Copyright © 2013 S. Karger AG, Basel.)

Offenders with mental illness challenge forensic systems throughout the world. Those with personality disorders present additional challenges. In this article, the authors describe relevant German legislation and the consequent forensic treatment of personality-disordered offenders in the German psychiatric and correctional systems, with a focus on the German state of Hessen. The development of laws and regulations are addressed, as are the parallels and distinctions between forensic hospitals and correctional settings. Current treatment approaches and programs are described. Research initiatives and future directions for the system, and comparisons with the system in the United States conclude the article.

Background: The aim of this study was to assess the potential for future violent behaviour comparing patients recruited from forensic and general psychiatric wards in Germany., Patients and Methods: Fifty patients were recruited from a forensic hospital and 29 from a general psychiatric hospital. In the weeks preceding discharge, structured assessments of the future risk of violent behaviour were completed using the HCR-20., Results: There was little difference in the risk presented by the two groups. Forensic patients presented an elevated risk of violence because of historical factors, while the risk among patients from general psychiatry was due to clinical symptoms., Conclusion: Some criminal offences could be prevented if more time and effort were spent in general psychiatric practice in identifying patients at high risk for violence and in reducing symptoms of psychoses before discharge.

BACKGROUND: Persons with schizophrenia have been found to be at increased risk for homicide as compared with the general population. The increased risk may be associated with the implementation of the policy of deinstitutionalization. METHOD: Persons with schizophrenia who had committed or attempted homicide in the German state of Hessen from 1992 to 1996 and in the Federal Republic of Germany from 1955 to 1964 were compared. RESULTS: Schizophrenia increased the risk of homicide 16.6 times (95% CI 11.2-24.5) in the recent cohort and 12.7 times (95% CI 11.2-14.3) in the older cohort. These odds ratios are not statistically different. The lack of appropriate services for chronic high-risk patients and the non-use of mental health services by first episode, acutely psychotic patients were associated with homicide. CONCLUSION: There has been no increase in the risk of homicide among persons with schizophrenia since the implementation of the policy of deinstitutionalization. The examination of the recent period suggests that the provision of specialized long-term care to persons with schizophrenia who are at high risk for violent behaviour and the use of mental health services by acutely psychotic persons may reduce the risk of homicide.

In borderline and antisocial personality disorder there is a close interaction between affect dysregulation and impulse control disorder. Different approaches are presented that focus on affective responses to experimental stimuli in these personality disorders. Results suggest that in borderline personality disorder intense emotional responses occur in the context of specific stressors, in particular fear of being abandoned. Evidence for a general emotional hyperreactivity was not found; on the contrary, female borderline subjects rather showed reduced emotional arousal. Regarding the psychopathic subtype of antisocial personality disorder, results provided strong support for the theory of emotional detachment, which may predispose to violence through a lack of feeling of fear or also of compassion which could counteract violent impulses. Consequences for psychotherapy in BPD are considered.

The analysis of the delinquency bringing disordered offenders into a hospital order institution reveals a lot of very conscious and well organized behavior during the criminal activity. This must be taken into account in therapy and prognosis.

According to German law, delinquents who are considered either not fully responsible or not responsible at all for their actions because of a mental disorder receive no punishment or a lesser degree of punishment in criminal trials. They may, however, be sentenced to psychiatric treatment either in a psychiatric hospital or in an addiction centre, if the risk of them committing such offenses in the future is considered to be high. This article reviews the current situation of mentally ill offenders in hospitals and explores possible developments in forensic psychiatry. It outlines the legal framework, and the current and developing treatment strategies, and finally raises the question of whether these developments will lead to further specialization of forensic psychiatry or to a reintegration of forensic knowledge into general psychiatry.

The analysis of 11 cases of violent offenses committed during hospital order treatment in the Haina Forensic Psychiatric Hospital between 1985 and 1991 showed that biographical and forensic variables are more powerful predictors of dangerousness than treatment and psychopathological data. In more than half of these cases it was at least questionable whether the individuals had been placed correctly inside the hospital order system. In comparison to data found in inmate populations and a new study from North America the question arises as to whether the treatment might not have contributed to increase dangerousness in at least some of our cases.
