BACKGROUND: The degree of overlap between schizophrenia (SCZ) and affective psychosis (AFF) has been a recurring question since Kraepelin's subdivision of the major psychoses. Studying nonpsychotic relatives allows a comparison of disorder-associated phenotypes, without potential confounds that can obscure distinctive features of the disorder. Because attention and working memory have been proposed as potential endophenotypes for SCZ and AFF, we compared these cognitive features in individuals at familial high-risk (FHR) for the disorders...

BACKGROUND: Many people with schizophrenia do not achieve a satisfactory treatment response with ordinary antipsychotic drug treatment. In these cases, various add-on medications are used, and valproate is one of these. OBJECTIVES: To examine whether:1. valproate alone is an effective treatment for schizophrenia and schizoaffective psychoses; and2. valproate augmentation of antipsychotic medication is an effective treatment for the same illnesses. SEARCH METHODS: We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials (July 2002; February 2007; July 2012; March 04, 2016)...

Toxoplasma gondii is one of the well-studied parasites because of its medical and veterinary importance, and its suitability as a model for cell biology and molecular studies. Latent toxoplasmosis in an immunocompetent host was considered benign until recently. The importance of this parasite has been steadily rising in the field of psychiatry and neurology as it has been implicated in numerous neuropsychiatric disorders. Researchers in India have unfortunately restricted themselves to finding the prevalence of toxoplasma antibodies in special populations and animals...

Patients experiencing psychoses and in need of antipsychotic agents may be exposed to a higher risk of myocardial infarction (MI) than the general population. As there have been no randomised studies investigating this association, a recent systematic review and meta-analysis included all observational studies that compared the incidence of MI among patients receiving antipsychotics v. no treatment. It found nine studies and calculated that the odds (risk) for developing MI were 1.88-fold higher in antipsychotic users compared with individuals who had not taken antipsychotic drugs...

REVIEW
Anita Riecher-Rössler
Interest is growing in the potential effect of gonadal hormones, prolactin, and the hypothalamic-pituitary-gonadal axis in schizophrenic psychoses. Many studies from clinical, epidemiological, and fundamental research have confirmed that oestradiol, the main component of oestrogens, can have protective effects in schizophrenic psychoses. Furthermore, many patients with schizophrenic psychoses-even in the untreated prodromal stages-have hyperprolactinaemia and gonadal dysfunction, with oestrogen deficiency in women and testosterone deficiency in men...

BACKGROUND: The categories of functional psychoses build on views of influential professionals. There have long been four main categories - affective, schizophrenic, schizoaffective/cycloid/reactive/polymorphic, and delusional/paranoid psychoses. The last three are included in "psychotic disorders". However, this dichotomy and the distinctions between categories may have been over-estimated and contributed to lack of progress.

BACKGROUND: In order to facilitate case identification of incident (untreated and recent onset) cases of psychosis and controls in three sites in India, Nigeria and Trinidad, we sought to understand how psychoses (or madness) were conceptualized locally. The evidence we gathered also contributes to a long history of research on concepts of madness in diverse settings. METHODS: We conducted focus group discussions and individual interviews to collect information about how informants in each site make sense of and respond to madness...

BACKGROUND AND OBJECTIVES: Affective versus nonaffective psychoses are today no longer regarded as mutually exclusive disorders. Theorists have recently highlighted the role of affective symptoms in the formation of paranoid beliefs, particularly negative beliefs about the self, interpersonal sensitivity, sleep disturbances, and worrying, which exist along a continuum in the general population. For the present study, we tested the bidirectional causal relationships between paranoia and affect...

This paper reviews the frequency of suicide and filicide in a literature of over 4000, and personal series of 321, childbearing psychoses. Suicide is rare during the acute episode, but the rate is high later in the mother's life and in first degree relatives. The filicide rate is high in depressive psychoses (4.5 %), but lower in episodes without overt depression (less than 1 %), and some of these appear to be accidental, without intent to kill.

BACKGROUND: Mental health profiles differ between boys and girls from puberty onwards. It is not known whether differences also extend to symptom presentation in schizophrenia spectrum disorders. It may be that girls and boys are not treated entirely equally by the professionals. AIMS: To study gender differences in symptom profiles, family adversities, pathway to care, and characteristics of inpatient treatment at the first episode of diagnosed schizophrenia spectrum disorder (F20-29) among adolescents aged 13-17...

Frontotemporal degeneration (FTD) in its behavioral variant (bvFTD) is probably one of the conditions that best illustrates the links between psychiatry and neurology. It is indeed admitted that between a third and half of patients with this condition, especially in early-onset forms, receive an initial diagnosis of psychiatric disorder (depression, schizophrenia, bipolar disorder) and are then referred to a psychiatric ward. BvFTD can thus be considered a neurological disorder with a psychiatric presentation...

OBJECTIVE: Few studies have characterized the epidemiology of first-episode psychoses in rural or urban settings since the introduction of early intervention psychosis services. To address this, the authors conducted a naturalistic cohort study in England, where such services are well established. METHOD: All new first-episode psychosis cases, 16-35 years old, presenting to early intervention psychosis services in the East of England were identified during 2 million person-years follow-up...

BACKGROUND: Polygenic risk scores (PRSs) have successfully summarized genome-wide effects of genetic variants in schizophrenia with significant predictive power. In a clinical sample of first-episode psychosis (FEP) patients, we estimated the ability of PRSs to discriminate case-control status and to predict the development of schizophrenia as opposed to other psychoses. METHODS: The sample (445 case and 265 control subjects) was genotyped on the Illumina HumanCore Exome BeadChip with an additional 828 control subjects of African ancestry genotyped on the Illumina Multi-Ethnic Genotyping Array...

A study of several hundred recurrent puerperal psychoses shows that about half of those with known onset recur in the same phase of reproduction, and half have onsets in different phases. Onsets in the same phase are especially a feature of prepartum psychosis and are the strongest indication of a specific trigger operating during pregnancy. Onsets in different phases provide a prima facie case for links between 'puerperal psychosis' and other reproductive onsets. They suggest that the 'picture puzzle' is not just about early onset puerperal psychosis, but a group of related reproductive triggers...

Primarily on the basis of epidemiological studies, recent research in psychiatry has established a robust link between urban living and psychosis. This paper argues first, that an experienced-based approach, moving beyond epidemiology, is needed in order to enable more fine-grained understandings of the city/psychosis nexus. The second part of the paper presents preliminary fieldwork results based on video-elicitation sessions with first-episode patients with psychotic disorders. These results lead to the generation of a series of hypotheses for further research on the role of density, sensory overload and social interaction as factors in the onset of non-affective psychoses...

AIMS: Lack of financial incentive is a frequently cited barrier to alcohol screening in primary care. The Quality and Outcomes Framework (QOF) pay for performance scheme has reimbursed UK primary care practices for alcohol screening in people with schizophrenia since April 2011. This study aimed to determine the impact of financial incentives on alcohol screening by comparing rates of alcohol recording in people with versus those without schizophrenia between 2000 and 2013. METHODS: Cross-sectional and retrospective cohort study...

Psychopathological symptoms and cognitive impairment are related to psychosocial functioning. However, the nature of the association of cognitive impairment with psychosocial functioning still remains under scrutiny. We aimed to examine the relationships of premorbid adjustment, lifetime psychopathological dimensions, and cognitive performance with the typical level of psychosocial functioning during the previous year. We assessed ninety patients with schizophrenia spectrum disorders and affective disorders with psychotic symptoms to collect data on premorbid adjustment, lifetime psychopathological dimensions, cognitive performance and psychosocial functioning...

Modern antipsychotic drugs are employed increasingly in the treatment of mood disorders as well as psychoses, stimulating interest in their possible contributions to altering suicidal risk. Clozapine remains the only treatment with an FDA-recognized indication for reducing suicidal risk (in schizophrenia). We carried out a systematic, computerized search for reports of studies involving antipsychotic drug treatment and suicidal behaviors. A total of 19 reports provide data with preliminary support for potential suicide risk-reducing effects of olanzapine, quetiapine, ziprasidone, aripiprazole, and asenapine in addition to clozapine, and provide some support for antipsychotic drug treatment in general...

Bipolar disorders, and other psychoses, are known to be triggered by a number of agents apart from the reproductive process. In some women, pregnant or recently delivered, psychosis may be due to these alternative triggers. There are substantial numbers of mothers suffering from childbearing psychoses, who have been prescribed bromocriptine or steroids, have had surgical operations or developed thyrotoxicosis. It is best to eliminate these episodes and cases from study samples of puerperal psychosis.
