S68. UNALTERED FRONTAL AND PREFRONTAL BRAIN RESPONSE DURING WORK MEMORY TASKS IN PATIENTS WITH A FIRST EPISODE PSYCHOSIS META-ANALYSIS STUDY

2019

BACKGROUND: There is extensive evidence that frontal and prefrontal cortex have abnormal functioning in patients with schizophrenia (Weinberger et al., 2001). For example, with functional magnetic resonance imaging (fMRI), multiple studies have shown altered activation during working memory tasks in these patients compared with controls (Adamczyk et al., 2017; Li et al., 2017). While most of the studies have been conducted in patients with chronic illness, whether these findings translate to individuals at the time of presenting with a First Episode Psychosis (FEP) is less well understood (Soldevila-Matias et al., 2018). The main objective of this study was to meta-analyze fMRI studies that…

S153. WHERE IS THE ABNORMAL BRAIN ACTIVITY IN FIRST EPISODE PSYCHOSIS?

2018

Abstract Background Recent review about functional magnetic resonance imaging (fMRI) in first episode psychosis (FEP) concluded that there is an abnormal connectivity involving the frontal temporal pathway similar to found in chronic schizophrenia (Mwansisya et al., 2017). Besides, thalamic circuits were also altered in chronic schizophrenia patients (Li et al., 2017). The present work gives a wider review of studies using functional magnetic resonance imaging techniques (fMRI) on first-episode psychotic patients, specifically focus on the main areas involved. Methods The review was made in accordance with the PRISMA guidelines (Moher et al., 2009). For each study, the following factors wer…

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…

The Body as the Union of the Psychic and the Physical in Bergson and Merleau-Ponty

1991

Within the framework of the theme of the First World Congress of Phenomenology “Fifty Years after Husserl: the Legacy of Husserl and Contemporary Phenomenology,” I wish to set forth in this brief article some reflections on the phenomenology of the body in Bergson and Merleau-Ponty. This analysis is not aimed directly at possible similarities and divergences between Bergson and Husserl.1 I have concentrated upon one of their heirs, Merleau-Ponty. I consider that the phenomenological method can throw light on the perennial problem of anthropology: the relationships between the psychic and the physical. On the other hand, as a student of Bergsonian thought, I would like to point out the simil…

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 influence of risk factors on the onset and outcome of psychosis: What we learned from the GAP study

2020

The GAP multidisciplinary study carried out in South London, recruited 410 first episode of psychosis patients and 370 controls; the aim was to elucidate the multiple genetic and environmental factors influencing the onset and outcome of psychosis. The study demonstrated the risk increasing effect of adversity in childhood (especially parental loss, abuse, and bullying) on onset of psychosis especially positive symptoms. Adverse life events more proximal to onset, being from an ethnic minority, and cannabis use also played important roles; indeed, one quarter of new cases of psychosis could be attributed to use of high potency cannabis. The “jumping to conclusions” bias appeared to mediate …
