Identifying gene-environment interactions in schizophrenia: contemporary challenges for integrated, large-scale investigations

2014

European Community Recent years have seen considerable progress in epidemiological and molecular genetic research into environmental and genetic factors in schizophrenia, but methodological uncertainties remain with regard to validating environmental exposures, and the population risk conferred by individual molecular genetic variants is small. There are now also a limited number of studies that have investigated molecular genetic candidate gene-environment interactions (G x E), however, so far, thorough replication of findings is rare and G x E research still faces several conceptual and methodological challenges. in this article, we aim to review these recent developments and illustrate h…

Valutazione delle funzioni esecutive in ambienti di Realtà Virtuale (RV): uno studio sui pazienti con Disturbo Ossessivo Compulsivo

2014

Lo studio è volto a valutare l'affidabilità e la validità della Realtà Virtuale come strumento per la valutazione neuropsicologica dei pazienti con Disturbo Ossessivo Compulsivo. Tale obiettivo è stato perseguito attraverso la somministrazione della batteria neuropsicologica e la versione virtuale del Multiple Errand Test (V-MET), sviluppato tramite il software NeuroVR, al fine di valutare le funzioni esecutive e la capacità di pianificazione su compiti complessi in pazienti con Disturbo Ossessivo Compulsivo (DOC) e in soggetti sani. Le performance esaminate, in particolar modo il tempo, l’accuratezza e gli errori nell’esecuzione dei compiti ed il numero delle inefficienze sembrano essere v…

Smoke High-Potency Cannabis and Become Psychotic Younger?

2016

PURPOSE: Cannabis use is associated with an earlier age of onset of psychosis (AOP). However, the reasons for this remain debated. METHODS: We applied a Cox proportional hazards model to 410 first-episode psychosis patients to investigate the association between gender, patterns of cannabis use, and AOP. RESULTS: Patients with a history of cannabis use presented with their first episode of psychosis at a younger age (mean years = 28.2, SD = 8.0; median years = 27.1) than those who never used cannabis (mean years = 31.4, SD = 9.9; median years = 30.0; hazard ratio [HR] = 1.42; 95% CI: 1.16-1.74; P < .001). This association remained significant after controlling for gender (HR = 1.39; 95% …

DOES CANNABIS USE WORSEN PSYCHOTIC SYMPTOM PRESENTATION?

2017

Background: While the relationship between cannabis and psychosis is well established, there is a lack of studies into whether cannabis use is associated with a particular pattern of symptoms at psychosis onset. Moreover, there is much evidence that psychotic experiences are common in the healthy population, and again their relationship with exposure to cannabis has been scarcely studied. We hypothesized that psychopathology in first-episode psychosis patients (FEP), and psychotic experiences in controls, would be qualitatively and quantitatively affected by pattern of cannabis use. Methods: The Operational CRITeria (OPCRIT) system, the CAPE (Community Assessment of Psychic Experiences), an…

SOME OF THE INDIVIDUAL DIFFERENCES IN RISK TO DEVELOP PSYCHOSIS AMONG CANNABIS USERS CAN BE EXPLAINED BY WHERE THEY LIVE AND BY THEIR AGE AT FIRST USE

2018

Background Cannabis use remains the most widely used recreational drug worldwide. Following from several USA states legalisation policies, European countries are reconsidering their cannabis laws. While a significant amount of Epidemiological evidence has reported that cannabis use increases the risk of psychosis it is still unclear: 1) what underpins individual differences in developing a psychotic disorder following cannabis use; 2) if variations in availability of cannabis have affected rate of Psychotic disorders across Europe. Methods Using detailed data on lifetime pattern of cannabis use from the EUGEI first episode case-control study (N=2300) and the available Incidence rates of Psy…

PREMORBID ADJUSTMENT AND CANNABIS USE IN FIRST-EPISODE-PSYCHOSIS PATIENTS. A CROSS-EUROPEAN CASE-CONTROL STUDY

The harmful effects of cannabis use and possible neuropsychological impairment associated with its use are a contentious topic of debate in both research and public health,as is thefact that cannabis use has been repeatedly shown to be a risk factor for the development of psychosis. Surprisingly, three different meta-analyses on cognition and cannabis, among schizophrenic patients, found better cognitive performance in patients with a lifetime use of cannabis (Potvin, Joyal, Pelletier, & Stip, 2008; Rabin, Zakzanis, & George, 2011; Yücel et al., 2012). This counterintuitive finding, coupled with the fact that most psychotic patients suffer from cognitive impairment (Reichenberg et al., 2009…
