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...

OBJECTIVE: The clinical profile of late-life depression (LLD) is frequently associated with cognitive impairment, aging-related brain changes, and somatic comorbidity. This two-site naturalistic longitudinal study aimed to explore differences in clinical and brain characteristics and response to electroconvulsive therapy (ECT) in early- (EOD) versus late-onset (LOD) late-life depression (respectively onset <55 and ≥55 years). METHODS: Between January 2011 and December 2013, 110 patients aged 55 years and older with ECT-treated unipolar depression were included in The Mood Disorders in Elderly treated with ECT study...

BACKGROUND: Around 35-45 % of people in contact with services for a first episode of psychosis are using cannabis. Cannabis use is associated with delays in remission, poorer clinical outcomes, significant increases in the risk of relapse, and lower engagement in work or education. While there is a clear need for effective interventions, so far only very limited benefits have been achieved from psychological interventions. Contingency management (CM) is a behavioural intervention in which specified desired behavioural change is reinforced through financial rewards...

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...

INTRODUCTION: This study explored schizotypy as a familial liability marker for schizophrenia-spectrum disorders (SSD) by examining: 1) the aggregation of schizotypy in families with a SSD patient, 2) whether familial resemblance of schizotypy is associated with ridge dissociations (RD), another SSD liability marker, 3) whether schizotypy aggregation patterns influence patients' psychopathology. METHODS: The sample comprised 30 SSD patients and 82 healthy first-degree relatives...

OBJECTIVES: The neurobiological underpinnings of bipolar I disorder are not yet understood. Previous structural neuroimaging studies of bipolar disorder have produced rather conflicting results. We hypothesize that clinical sub-phenotypes of bipolar I disorder defined by their psychotic symptoms, especially those with mood-incongruent psychotic features, may have more extensive structural brain abnormalities. METHODS: We investigated structural brain alterations in patients with first-episode mania (n = 55) with mood-congruent (n = 16) and mood-incongruent (n = 32) psychotic features, as well as those without psychotic symptoms (n = 7), relative to healthy subjects (n = 56)...

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...

Neuroactive steroids may play a role in the pathophysiology of psychotic disorders, but few studies examined this issue. We compared serum levels of cortisol, testosterone, dehydroepiandrosterone, and progesterone between a representative sample of first-episode psychosis (FEP) patients and age- and gender-matched healthy subjects. Furthermore, we analyzed the associations between neuroactive steroids levels and the severity of psychotic symptom dimensions. Male patients had lower levels of progesterone than controls (p = 0...

INTRODUCTION: Cannabis use is very frequent in bipolar disorder and has been found to increase the duration and frequency of manic symptoms while decreasing those of depression. Bipolar patients who use cannabis were shown to have poorer compliance to treatment, more symptoms that are psychotic and a worse prognosis than patients who do not. In this study, we have evaluated the importance of cannabis use among bipolar patients admitted to the Psychiatric Hospital of the Cross, Lebanon (Hôpital Psychiatrique de la Croix [HPC]) as well as the clinical differences between cannabis users and non-users...

BACKGROUND AND AIMS: Research suggests that tobacco smokers may develop psychosis at an earlier age than non-smokers, with effects on psychotic symptoms. We aimed to test the difference in age of onset of psychosis between smokers and non-smokers . Design Self-report data was collected from smokers and non-smokers in a population of first episode psychosis patients. SETTING: Outpatient first episode psychosis programme in Santander (Cantabria), Spain. PARTICIPANTS: Three hundred and ninety seven patients (226 male, 171 female) who agreed to take part between 2001 and 2011...

Recent evidence suggests the involvement of Toxoplasma gondii infection in the emergence of psychotic and affective disorders. In this report, we describe the case of a young Brazilian woman affected by recurrent ocular toxoplasmosis and presenting with a manic episode with psychotic features in the context of a diagnosis of Bipolar Disorder (BD), type I. We observed a relationship between ocular manifestations and the clinical course of bipolar illness, confirmed by molecular analyses (nested-PCR), as well as by the high level of T...

Objectives Binocular depth inversion illusion (BDII) represents an illusion of visual perception that involves higher-order visual and cognitive processes. Its impairment has been linked to psychotic conditions and identified as a marker for at risk mental states. The endogenous cannabinoid system (ECS) is involved in various neurophysiological processes. One of its key components, anandamide, is involved in the pathophysiology of schizophrenia. Little is known about its impact on BDII alterations. Therefore, we explored associations between BDII and anandamide levels...

OBJECTIVE: This review critically examines the structural neuroimaging evidence in psychotic illness, with a focus on longitudinal imaging across the first-episode psychosis and ultra-high-risk of psychosis illness stages. METHODS: A thorough search of the literature involving specifically longitudinal neuroimaging in early illness stages of psychosis was conducted. The evidence supporting abnormalities in brain morphology and altered neurodevelopmental trajectories is discussed in the context of a clinical staging model...

BACKGROUND: Understanding morphologic changes in vulnerable and early disease state of schizophrenia (SZ) may provide further insight into the development of psychosis. METHOD: Whole brain voxel-based morphometry was performed to identify gray matter (GM) regional differences in 60 individuals with SZ during their first psychotic episode (FE-SZ), 31 individuals at genetic high risk for SZ (GHR-SZ) individuals, and 71 healthy controls. RESULTS: Significant differences were found in several regions including the prefrontal cortex, parietal lobe, temporal lobe, hippocampus, occipital lobe, and cerebellum among the three groups (p<0...

The first psychotic episode is classically viewed as a critical period which management is important in determining the long-term outcome of the schizophrenia (SCZ). For this reason, the duration of untreated illness (DUI), defined as the interval between the onset of the psychiatric disorder and the administration of the first pharmacological treatment, is a clinical variable that has been increasingly investigated due to its potentially modifiable nature and its value as a predictor of outcome. DUI is poorly applicable and highly unreliable in psychosis...

BACKGROUND: Childhood trauma has been associated with a more severe clinical expression of bipolar disorder (BD). However, the results that specifically associated traumatic events and psychotic features in BD have been inconsistent, possibly due to the low resolution of the phenotypes being used. METHODS: 270 normothymic patients with BD completed the Childhood Trauma Questionnaire (CTQ) and the Peters Delusion Inventory (PDI) that assessed 21 delusional beliefs...

Early intervention for psychotic disorders, a growing international priority, typically targets help-seeking populations with emerging psychotic ("positive") symptoms. We assessed the nature of and degree to which treatment of individuals at high risk for psychosis preceded or followed the onset of positive symptoms. The North American Prodrome Longitudinal Study-2 collected psychosocial treatment histories for 745 (98%) of 764 high-risk participants (M age = 18.9, 57% male, 57.5% Caucasian, 19.1% Hispanic) recruited from 8 North American communities...

Psychotic disorders affect ~3% of the general population and are among the most severe forms of mental diseases. In early stages of psychosis, clinical aspects may be difficult to distinguish from one another. Undifferentiated psychopathology at the first-episode of psychosis (FEP) highlights the need for biomarkers that can improve and refine differential diagnosis. We investigated gene expression differences between patients with FEP-schizophrenia spectrum (SCZ; N=53) or FEP-Mania (BD; N=16) and healthy controls (N=73)...

Ekbom syndrome or delusional parasitosis is a rare disease characterized by the unwavering conviction of having cutaneous infestation of insects or parasites. This is a monothematic delusion of hallucinatory origin that typically affects older women. We report the case of three patients with delusional parasitosis in different clinical settings. The first patient suffered from isolated delusional parasitosis corresponding to the condition described by Karl Ekbom. The second case suffered from secondary delusional parasitosis, occurring in the setting of leukoencephalopathy (CADASIL)...

BACKGROUND: Formal thought disorder (FTD) is associated with poor outcome in established psychotic illnesses and it can be assessed as a categorical or dimensional variable. However, its influence on functional outcome and hospitalisation patterns in early psychosis has not been investigated. We evaluated the relationship between FTD and these outcomes in a first episode psychosis (FEP) sample. MATERIALS AND METHODS: A mixed diagnostic FEP cohort was recruited through an Early Intervention in Psychosis Service in Ireland...
