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…

O4.8. CAN YOU SPOT EMOTIONS? FACIAL EMOTION RECOGNITION AND GENETIC RISK FOR PSYCHOSIS

2019

Background Facial emotion recognition (FER) is a key component of social cognition which has been found consistently impaired in schizophrenia. Deficits in global facial affect recognition have been also found in First Episode Psychosis (FEP) with the same severity as at further stages, especially for anger recognition. Literature to date has shown intermediate emotion recognition ability in either people with family history for psychotic disorders and unaffected relatives of psychotic patients, in a continuum between patients and healthy controls. Furthermore, Polygenic Risk Score (PRS) for schizophrenia has been found associated with social cognition, especially with facial emotion identi…

S118. TRANSDIAGNOSTIC SYMPTOM DIMENSIONS OF PSYCHOSIS AND THE PREDICTIVE ROLE OF PREMORBID ADJUSTMENT AND COGNITIVE CHARACTERISTICS IN THE MULTINATIO…

2020

Abstract Background A symptom dimension approach may best examine the heterogeneous expression of psychosis. However, whether and how premorbid predisposition and cognitive factors explain phenotypes variation is still debated. This study aimed to test the predictive value of combined cognition and premorbid adjustment on transdiagnostic symptom dimensions in a large sample of people suffering from the first episode of psychosis (FEP). Methods FEP patients were part of the EUGEI study. Psychopathology was rated using the OPerational CRITeria system. Multidimensional item response modelling estimate a bifactor model of psychosis by Mplus, composed of a general factor and five specific sympto…

S126. THE RELATION OF THE PSYCHOSIS CONTINUUM WITH SCHIZOPHRENIA POLYGENIC RISK SCORE AND CANNABIS USE

2020

Abstract Background There has been much debate about whether research into psychosis should be conducted using symptom dimensions as opposed to diagnostic categories. Indeed, dimensions, like categories, may be practical but arbitrary tools for research and clinical practice; hence, they should not be based on psychometric data only. The aim of this study was to externally validate empirically derived symptom dimensions using combined genetic and environmental data. Specifically, we examined the hypothesis that the continuous multivariate distribution of psychosis is a function of cannabis use and genetic liability to schizophrenia, as summarised by polygenic risk score (SZ-PRS). Methods As…

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…

S114. THE EFFICACY OF “URGENT CONSULTATION REQUEST”; PRELIMINARY ANALYSIS OF A REAL-WORLD APP (REMIDCARE) FOR EARLY PSYCHOSIS

2020

Abstract Background Patients are clamming for more personalized and closer clinical attention (Bonet et al. 2018). To this end, we developed RemindCare app. The app conducts daily and weekly assessments and this information is used to prevent relapses, to improve the therapeutic alliance and it is automatically included at the electronic clinical record of the hospital. Moreover, patients can contact clinicians by an “Urgent Consultation Request” (UCR), which is answered by a phone call in a period of 24-48h. This app was introduced in clinical practice in October 2018. Since then, 81 patients met criteria for inclusion and 57/81 (71%) started using the app. The aim of this study is to anal…

Exploring the Neuropsychiatric Sequalae of Perceived COVID-19 Exposure in College Students: A Pilot Digital Phenotyping Study

2022

The urgency to understand the long-term neuropsychiatric sequala of COVID-19, a part of the Post-Acute COVID-19 Syndrome (PACS), is expanding as millions of infected individuals experience new unexplained symptoms related to mood, anxiety, insomnia, headache, pain, and more. Much research on PACS involves cross sectional surveys which limits ability to understand the dynamic trajectory of this emerging phenomenon. In this secondary analysis, we analyzed data from a 4-week observational digital phenotyping study using the mindLAMP app for 695 college students with elevated stress who specified if they were exposed to COVID-19. Students also completed a biweekly survey of clinical assessments…
