F145. WHAT ARE THE MAIN BRAIN CHANGES IN FMRI AFTER TREATMENT IN FIRST EPISODE PSYCHOSIS? A SYSTEMATIC REVIEW

2018

Abstract Background There are many studies using structural MRI to explore the longitudinal course of F Episode Psychosis (FEP).2 On the other hand, there is a lack of functional MRI studies examining the longitudinal course of FEP. The aim of this work is to make a literature systematic review of these studies, to summarize the knowledge about longitudinal course of functional brain activity in FEP. Methods We followed the PRISMA guidelines for conducting systematic reviews and combined the use of electronic and manual systematic search methods, in the principal databases (MedLine, PubMed and Web of Science) using the query “longitudinal” AND “fMRI” AND “first episode psychosis” OR “first …

F99. FIRST EPISODE PSYCHOSIS PATIENTS WHO USED CANNABIS DEVELOP THEIR ILLNESS AT A SIGNIFICANTLY YOUNGER AGE THAN THOSE WHO NEVER USED CONSISTENTLY A…

2018

Abstract Background Patients presenting to psychiatric services with their first episode of psychosis (FEP) report higher rates of previous cannabis use than the general population (Donoghue et al., 2011; Myles, Myles and Large, 2016). Evidence suggested that patients suffering from psychosis with a history of cannabis use have an earlier age of onset of psychosis (AOP) than those who never used it (Di Forti et al., 2013). We aim to investigate if the reported association between use of cannabis and AOP is consistent across different countries, once having taken into account different patterns of cannabis use (i.e. frequency of use and age at first use). Methods We analysed data on patterns…

EPA-1417 – Migration history and first episode psychosis: Results from EUGEI project- Italy

2014

The excess of psychosis among migrants and ethnic minorities is a well defined phenomenon in North Europe, while it should be still demonstrated in south Europe. Because of the variation in prevalence and distribution of risk factors in different national contexts, similar studies in different countries are needed to test the hypotheses and to ensure the generalizability of the findings. Moreover, available studies have been mostly focused on risk factors of psychosis during the post migration phase (such as ethnic fragmentation, unemployment, etc) and among well established ethnic minorities (second and further generations of migrants). In Italy, first generation migrants are still the lar…

The relationship of symptom dimensions with premorbid adjustment and cognitive characteristics at first episode psychosis: Findings from the EU-GEI s…

2021

Premorbid functioning and cognitive measures may reflect gradients of developmental impairment across diagnostic categories in psychosis. In this study, we sought to examine the associations of current cognition and premorbid adjustment with symptom dimensions in a large first episode psychosis (FEP) sample. We used data from the international EU-GEI study. Bifactor modelling of the Operational Criteria in Studies of Psychotic Illness (OPCRIT) ratings provided general and specific symptom dimension scores. Premorbid Adjustment Scale estimated premorbid social (PSF) and academic adjustment (PAF), and WAIS-brief version measured IQ. A MANCOVA model examined the relationship between symptom di…

The long-term use of psychiatric services within the Open Dialogue treatment system after first-episode psychosis

2017

AbstractOpen Dialogue is a family-oriented early intervention model for mental health problems developed in the health district of Western Lapland, Finland. In the present study, the aim was to describe how psychiatric services were used in Western Lapland after decades of first-episode psychosis services, and to analyze how baseline characteristics were related to re-admission rates and the total duration of psychiatric treatment in geographical area where Open Dialogue approaches were developed and efforts made to systematically apply them to all psychiatric treatments. The data were obtained from the medical histories of patients who had first-episode psychosis in 1992–2005 and who lived…

Association of extent of cannabis use and psychotic like intoxication experiences in a multi-national sample of first episode psychosis patients and …

2021

AbstractBackgroundFirst episode psychosis (FEP) patients who use cannabis experience more frequent psychotic and euphoric intoxication experiences compared to controls. It is not clear whether this is consequent to patients being more vulnerable to the effects of cannabis use or to their heavier pattern of use. We aimed to determine whether extent of use predicted psychotic-like and euphoric intoxication experiences in patients and controls and whether this differs between groups.MethodsWe analysed data on patients who had ever used cannabis (n = 655) and controls who had ever used cannabis (n = 654) across 15 sites from six countries in the EU-GEI study (2010–2015). We used multiple regres…

Schizophrenia polygenic risk score and cannabis use modify psychosis expression in first episode psychosis patients and population controls

2019

AbstractBackgroundDiagnostic categories within the psychosis spectrum are widely used in clinical practice, however psychosis may occur on a continuum. Therefore, we explored whether the continuous distribution of psychotic symptoms across categories is a function of genetic as well as environmental risk factors, such as polygenic risk scores (PRSs) and cannabis use.MethodsAs part of the EU-GEI study, we genotyped first episode psychosis patients (FEP) and population controls, for whom transdiagnostic dimensions of psychotic symptoms or experiences were generated using item response bi-factor modelling. Linear regression was used, separately in patients and controls, to test the association…
