Failure to find association between childhood abuse and cognition in first-episode psychosis patients

AbstractThis study investigated the relationship between severe childhood abuse and cognitive functions in first-episode psychosis patients and geographically-matched controls. Reports of any abuse were associated with lower scores in the executive function domain in the control group. However, in contrast with our hypothesis, no relationships were found amongst cases.

Better IQ but worse Premorbid Academic Adjustment in cannabis-users psychotic patients: another brick in the intuition

Purpose: several studies report that patients with psychosis who used cannabis in their lifetime have a better cognitive performance than those who did not and this association is most likely due to a better premorbid functioning. We aimed to test the hypothesis of a better premorbid functioning in First Episode Psychosis (FEP) cannabis-using and non-using patients coming from different European countries. Materials and Methods: 1.745 people (746 cases; 999 healthy controls) completed the assessment for Intellectual Quotient (IQ) (WAIS-brief version) premorbid adjustment (Premorbid Adjustment Scale – PAS) and cannabis use (CEQ-Revised). We first obtained two main factors from PAS: “Premorbi…

Are there specific neuropsychological deficits underlying poor insight in first episode psychosis?

Insight in psychosis is a multi-dimensional phenomenon, and has been hypothesised to have some sort of neuropsychological basis. It is unclear to what extent specific neuropsychological abilities are able to predict insight beyond the effect of generalised cognitive ability. We aimed to test this, alongside the relationship of insight with illness duration and diagnosis, in a sample of first episode psychosis patients. We recruited 102 patients experiencing their first episode of psychosis and assessed their insight, symptoms, diagnosis as well as administering a full neuropsychological battery. Low insight was related to worse performance in a variety of neuropsychological tasks. Regressio…

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

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).

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

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…

Psychological and Psychiatric Impact of the Coronavirus Pandemic

On the eve of 4th May, the date when the lockdown was to end, people could stand it no more! The wait was not only hard, but also full of doubts about what level of freedom people could enjoy in their future. That caused a serious crisis which came after a previous, serious legitimacy crisis that the western political system, and not only Italian, had been going through for a long time. In an interview available in L’Avvenire of last 15th April, the ninety-year-old sociologist Edgar Morin defined the present situation as a “poly-crisis.” Long ago, citizens had already ceased to trust the political system and every other type of power. But, since nowadays, in Europe and the United States, th…

Are Polygenic Risk Scores for Major Mental Disorders Associated with General or Specific Psychosis Symptom dimensions?

Background Psychotic symptoms can be conceptualised as dimensions of psychopathology cutting across diagnostic boundaries. Thus, they might be considered enhanced quantitative phenotypes to relate to genetic variants as summarised by Polygenic Risk Scores (PRSs) for Major Mental Disorders (MMDs), including Schizophrenia (SZ), Bipolar Disorder (BP), and Major Depressive Disorder (MDD). The objectives of this study were to: 1) identify the dimensional structure of symptoms at First Episode Psychosis (FEP), testing whether a bi-factor model statistically fits the conceptualization of psychosis as a single common construct (general psychosis factor) while also recognising multidimensionality (p…

Eventi di vita stressanti in un campione di pazienti affetti da psicosi all’esordio: prevalenza, sintomatologia ed età d’esordio

Introduzione: Un consistente numero di studi suggerisce un’elevata prevalenza di eventi traumatici nella storia di soggetti con disturbi psicotici (Shevlin et al, 2008). Piu’ che l’impatto di un singolo evento di vita stressante, l’esposizione cumulativa ad esperienze traumatiche sembra incrementare il rischio di psicosi (van Winkel et al, 2008).

The Relationship Between Polygenic Risk Scores and Cognition in Schizophrenia

Abstract Background Cognitive impairment is a clinically important feature of schizophrenia. Polygenic risk score (PRS) methods have demonstrated genetic overlap between schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), educational attainment (EA), and IQ, but very few studies have examined associations between these PRS and cognitive phenotypes within schizophrenia cases. Methods We combined genetic and cognitive data in 3034 schizophrenia cases from 11 samples using the general intelligence factor g as the primary measure of cognition. We used linear regression to examine the association between cognition and PRS for EA, IQ, schizophrenia, BD, and MDD. The results wer…

S77. JUMPING TO CONCLUSIONS AND FACIAL EMOTION RECOGNITION IMPAIRMENT IN FIRST EPISODE PSYCHOSIS ACROSS EUROPE

Abstract Background Jumping to conclusions (JTC) is a well-established reasoning and data gathering bias found in patients with psychosis even at illness onset (First Episode Psychosis, FEP). Preliminary work in this field focused primarily on the association with delusions, although jumping to conclusions has also been found in non-deluded schizophrenia patients after remission, and in individual with at risk mental state. Moreover, psychotic patients tend to show impairments in social cognition, struggling in identifying, processing and interpreting social clues. Deficits in facial emotion recognition (FER) – a key component of the construct – represent a well-replicated finding in schizo…

T110. FIRST EPISODE PSYCHOTIC PATIENTS WITH A HISTORY OF FREQUENT CANNABIS USE EXPRESS MORE POSITIVE SYMPTOMS AT ILLNESS ONSET THAN THOSE WHO NEVER USED CANNABIS

Abstract Background Robust evidence has demonstrated that cannabis use increases the risk to develop psychotic disorders. However, a limited number of studies have investigated if and how cannabis use influences psychopathology profiles at first episode psychosis (FEP). Based on the evidence that dopamine dysfunction contributes to explain positive symptoms in psychosis, and that the main cannabis’ psychoactive component, Δ9-Tetrahydrocannabinol (THC), modulates the dopamine system, we hypothesise that: 1) positive symptoms at FEP are more common among psychotic patients who used cannabis compared with never users; 2) this association is a dose-response relationship.

Il problema della violenza nelle persone affette da schizofrenia pone spinosi dilemmi clinici e sociali. Da una parte, il comportamento aggressivo nella schizofrenia può essere una pericolosa, anche se rara, complicanza della malattia. I medici sono tenuti ad anticipare, valutare, gestire e ridurre i rischi di violenza dei loro pazienti, con interventi e trattamenti adeguati. D’altra parte, pazienti psichiatrici capaci di decidere autonomamente, spesso riducono o sospendono il trattamento nel corso del tempo, il che è un loro diritto, e in ogni caso molte cause di violenza non possono essere trattate con i farmaci (Swanson et al., 2008a).

In summary, our results showed high percentages of psychiatric morbidity (44%), especially anxiety and depression. Female inmates declared to be most stressed by the distance from family and loved ones, and they did not present any antisocial personality diagnosis. They also showed a resilient reaction to their situation, because more than a half of women requested a supportive psycho…

FIRST EPISODE PSYCHOSIS PATIENTS ACROSS EUROPE DIFFER IN INTELLECTUAL QUOTIENT (IQ) AND EXPOSURE TO ENVIRONMENTAL HAZARDS

Background Children who later develop Schizophrenia on average are more likely to present with lower IQ; this has been considered evidence for the neurodevelopmental theory of schizophrenia. Though, recent studies have shown that first episode psychosis patients with a history of cannabis use have significantly higher premorbid and current IQ compared to those who never used it. This suggests that abnormal early neurodevelopment does not explain the aetiology of all cases of Schizophrenia, leaving space to environmental hazards. The present study aims to: investigate differences in IQ, as a marker of neurodevelopment, and in exposure to environmental risk factors in a large sample first epi…

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.

IS THE ERA OF CANDIDATE GENES X CANNABIS USE REALLY DEAD?

Background: Historically, gene X environment examinations in psychotic disorders have employed candidate gene methods and environmental determinants impacting on similar biological mechanisms. However, genome wide association studies (GWAS) show that many variants associated with schizophrenia have a modest effect size on risk. In this respect, it is unclear whether the effect of cannabis on psychosis phenotypes is modified by a few genes, e.g. those involved in dopamine signalling, or by the overall genetic susceptibility to schizophrenia. Indeed, candidate gene approaches might be complementary to GWAS to test gene X cannabis interaction. We aimed to investigate the interactive effects of…

Interesting findings showed also strong association with lower cognitive functioning in psychotic patients, which in turn has been shown as a candidate intermediate phenotype for psychosis. Overall, findings to date could suggest a shared genetic liability between the occurrence of JTC and psychosis, potentially via IQ. The present study aims to investigate whether the presence of…

Cannabis users have higher premorbid IQ than other patients with first onset psychosis.

Background: A number of studies have reported that patients with psychosis who use cannabis have better cognitive performance than those who do not. This is surprising as cannabis can impair cognition in healthy subjects.

AbstractWe evaluated the association between healthy lifestyles and academic achievement in a sample of 373 adolescent Italian students. Specifically, we investigated on the association between use of illegal drugs, habits to practice a regular physical, typology of diet, levels of social support, levels of self-esteem, level of Internet use, perceived stress and amount of sleep and academic achievement. Academic performance was positively correlated with good diet, perceived social support, and self-esteem. A statistically significant difference emerged between students with high versus low correct grade point averages in relation to lifetime and current use of illegal drugs. Last, academi…

Jumping To Conclusions, General Intelligence, And Psychosis Liability: Findings From The Multi-Centre EU-GEI Case-Control Study

AbstractBackgroundThe “jumping to conclusions” (JTC) bias is associated with both psychosis and general cognition but their relationship is unclear. In this study, we set out to clarify the relationship between the JTC bias, IQ, psychosis and polygenic liability to schizophrenia and IQ.Methods817 FEP patients and 1294 population-based controls completed assessments of general intelligence (IQ), and JTC (assessed by the number of beads drawn on the probabilistic reasoning “beads” task) and provided blood or saliva samples from which we extracted DNA and computed polygenic risk scores for IQ and schizophrenia.ResultsThe estimated proportion of the total effect of case/control differences on J…

Smoke High-Potency Cannabis and Become Psychotic Younger?

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).

Cognitive thought diary in supportive psychology for people undergoing radiotherapy: a feasibility study

BAC KGROUND: Radiation therapy (RT ) has become one of the most widely-used and efficient treatments for cancer; nevertheless, people who undergo radiotherapy suffer the physical and psychological consequences of this stressful treatment, in addition to the psychosocial distress related to cancer. However, a Radiotherapy Unit is often a place where several patients crowd in from various hospitals with restricted timetables and, for logistic reasons, it is not easy to provide regular psychological sessions for each one. It is important to find a setting that allows us the involvement of the largest number of patients referred to the unit. In this study, we aimed to evaluate the feasibility a…

5.4 BIOLOGICAL AND EPIDEMIOLOGICAL EXAMINATION OF TRANSDIAGNOSTIC AND SPECIFIC SYMPTOM DIMENSIONS AT PSYCHOSIS ONSET: FINDINGS FROM THE EUGEI STUDY

Abstract Background Current diagnostic models of psychosis have been questioned since Kraepelin’s original dichotomy of dementia praecox and manic depression. Indeed, increasing evidence has suggested that a dimensional approach might be a valid alternative platform for research. However, while an increasing number of studies have investigated how environmental risk factors for affective and non-affective psychosis map onto symptom dimensions, only a few have examined these dimensions in relation to genetic variants as summarised by Polygenic Risk Score (PRS). Furthermore, no studies have examined the putative effect of PRS for Schizophrenia (SZ), Bipolar Disorder (BP), and Major Depressive…

What does augment the risk to use cannabis on an everyday-basis in psychotic patients?

Introduction There are strong enough evidences of the fact that risk of psychosis is augmented by cannabis use. In a recent analysis, the strongest predictor of case-control status was daily-skunk use, i.e. the ORs for skunk users increase with the frequency of use5. We know also that FEP who smoked cannabis in their lifetime are less neuropsychologically impaired i.e. they have better premorbid and current IQ6. In this study we wanted to test what augments the probability to be everyday users, taking into account premorbid social and academic adjustment and cognition as predictors, along with age at first cannabis-use and % of THC in cannabis used. Methods The sample was made of 834 First …

La psicoterapia come laboratorio di metafore. Una prospettiva integrata di psicoterapia cognitivista e musicoterapia

Il trend attuale in campo epistemologico e teorico-concettuale aspira alla scoperta di linguaggi condivisi e condivisibili tra i diversi approcci psicoterapeutici. Spesso è accaduto che all’avvicinamento tra tecniche a matrice diversa non seguisse un accurato studio teorico orientato a definire e fornire un substrato concettuale a ciò che si era già rivelato utile nella pratica. Di contro, gli sviluppi delle neuroscienze hanno fornito oggi elementi molto utili alla comprensione di ciò che accade nelle stanze di psicoterapia; a partire dalla contestazione di antiche acquisizioni, date per consolidate, come la presunta incapacità della cellula neuronale di riprodursi e arborizzare in età adul…

The Relationship Between Dissociative Experiences and Cannabis Use: a Systematic Review

Purpose of Review This systematic review aimed to investigate the relation between cannabis use and dissociation. Recent Findings Four analytical and 14 descriptive cross-sectional studies were included. There is no variation in the rates of cannabis use among individuals with dissociative experiences compared with the general population. In addition, the prevalence of dissociative disorders in subjects using cannabis is not different from those not using cannabis. The majority of the studies employed inadequate sampling procedures and a concurrent or retrospective assessment of the two variables, which might have increased the risk of bias, and only a few of them controlled for potential c…

Use of multiple Polygenic Risk Scores for distinguishing Schizophrenia-spectrum disorder and Affective psychosis categories; the EUGEI study

ABSTRACTSchizophrenia (SZ), Bipolar Disorder (BD) and Depression (D) run in families. This susceptibility is partly due to hundreds or thousands of common genetic variants, each conferring a fractional risk. The cumulative effects of the associated variants can be summarised as a polygenic risk score (PRS). Using data from the EUGEI case-control study, we aimed to test whether PRSs for three major psychiatric disorders (SZ, BD, D) and for intelligent quotient (IQ) as a neurodevelopmental proxy, can discriminate affective psychosis (AP) from schizophrenia-spectrum disorder (SSD). Participants (573 cases, 1005 controls) of european ancestry from 17 sites as part of the EUGEI study were succes…

Background FEP patients who use cannabis experience more frequent 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 FEP patients and controls and whether this differs between groups.

Premorbid Adjustment and IQ in Patients With First-Episode Psychosis: A Multisite Case-Control Study of Their Relationship With Cannabis Use

Abstract Psychotic patients with a lifetime history of cannabis use generally show better cognitive functioning than other psychotic patients. Some authors suggest that cannabis-using patients may have been less cognitively impaired and less socially withdrawn in their premorbid life. Using a dataset comprising 948 patients with first-episode psychosis (FEP) and 1313 population controls across 6 countries, we examined the extent to which IQ and both early academic (Academic Factor [AF]) and social adjustment (Social Factor [SF]) are related to the lifetime frequency of cannabis use in both patients and controls. We expected a higher IQ and a better premorbid social adjustment in psychotic p…

Better social but worse academic premorbid adjustment in cannabis-users psychotic patients across Europe

Background: Several studies report that patients with psychosis who used cannabis have a better cognitive performance than those whodid not (Rabin et al. 2011). In a previous study we found out a higher premorbid IQ, and a better IQ in psychotic patients who smoked cannabis in their lifetime, and our findings were consistent with the idea that this association is due to a better premorbid functioning rather than to an ameliorative effect of cannabis use on cognitive performance (Ferraro et al., 2013). A number of authors have hypothesized that psychotic patients who consume cannabis constitute a differentiated subgroup of patients that have better cognitive and social skills, necessary to e…

O2.1. FIRST EPISODE PSYCHOSIS PATIENTS ACROSS EUROPE DIFFER IN INTELLECTUAL QUOTIENT (IQ) AND EXPOSURE TO ENVIRONMENTAL HAZARDS

Abstract Background Children who later develop Schizophrenia on average are more likely to present with lower IQ; this has been considered evidence for the neurodevelopmental theory of schizophrenia. Though, recent studies have shown that first episode psychosis patients with a history of cannabis use have significantly higher premorbid and current IQ compared to those who never used it. This suggests that abnormal early neurodevelopment does not explain the aetiology of all cases of Schizophrenia, leaving space to environmental hazards. The present study aims to: investigate differences in IQ, as a marker of neurodevelopment, and in exposure to environmental risk factors in a large sample …

Background Jumping to conclusions (JTC) is a well-established reasoning and data gathering bias found in patients with psychosis even at illness onset (First Episode Psychosis, FEP). Preliminary work in this field focused primarily on the association with delusions, although jumping to conclusions has also been found in non-deluded schizophrenia patients after remission, and in individual with at risk mental state. Moreover, psychotic patients tend to show impairments in social cognition, struggling in identifying, processing and interpreting social clues.

Cannabis Users and Premorbid Intellectual Quotient (IQ)‏

• The chapter focuses on premorbid Intellectual Quotient (IQ) in cannabis users, one of the most controversial topics in studies on the harmful effects of cannabis use on cognition. • Several studies have ascertained acute and residual effects of cannabis use in the memory domain, but only a minimal general cognitive effect after a long-term period of abstinence. • A number of longitudinal studies were able to obtain IQ measures before and after cannabis consumption, but they yielded discordant findings. • Authors, however, observed a relationship between higher premorbid IQ and recreational or discontinued use while a lower premorbid IQ resulted as a predictor for regular or heavy cannabis…

The contribution of cannabis use to variation in the incidence of psychotic disorder across Europe (EU-GEI): a multicentre case-control study.

Background: Cannabis use is associated with increased risk of later psychotic disorder but whether it affects incidence of the disorder remains unclear. We aimed to identify patterns of cannabis use with the strongest effect on odds of psychotic disorder across Europe and explore whether differences in such patterns contribute to variations in the incidence rates of psychotic disorder. Methods: We included patients aged 18–64 years who presented to psychiatric services in 11 sites across Europe and Brazil with first-episode psychosis and recruited controls representative of the local populations. We applied adjusted logistic regression models to the data to estimate which patterns of canna…

Il riconoscimento delle emozioni facciali all’esordio psicotico.

La capacità di riconoscere le emozioni facciali fa parte del più ampio dominio relativo alla cognizione sociale. Nel disturbo schizofrenico è presente un deficit dell’esperienza emotiva e dell’espressione appropriata delle emozioni. Numerosi studi hanno riscontrato in questi soggetti deficit a carico della capacità di riconoscimento delle emozioni facciali nonché della modulazione emotiva della voce. L’obiettivo dello studio è stato quello di indagare la presenza di un deficit a carico del riconoscimento delle emozioni facciali nei soggetti con esordio psicotico, posti a confronto con un gruppo di controlli sani. In particolare, si ipotizza nei pazienti una relazione tra il deficit di ricon…

DOES POLYGENIC RISK SCORE FOR SCHIZOPHRENIA IMPACT ON JUMPING TO CONCLUSIONS? PRELIMINARY FINDINGS FROM THE EU-GEI CASE-CONTROL STUDY

Background: Jumping to conclusions (JTC) is a reasoning and data gathering bias that results in the tendency to require less evidence and make hasty decisions. Preliminary work on reasoning bias focused primarily on the association with delusions, although jumping to conclusions has also been found in non-deluded schizophrenia (SZ) patients. Literature to date has shown JTC as a well-established bias in psychosis even at First Episode Psychosis (FEP), after remission, and in individuals with at risk mental state. Furthermore, JTC has been found to be associated with proneness to psychotic-like experiences in the general population. In teresting findings showed also an association with lower…

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

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…

F115POLYGENIC RISK SCORES FOR SCHIZOPHRENIA, BIPOLAR, AND MAJOR DEPRESSIVE DISORDERS PREDICT TRANSDIAGNOSTIC SYMPTOM DIMENSIONS AT FIRST EPISODE PSYCHOSIS

Background: The value of the nosological distinction between non-affective and affective psychosis has consistently been challenged. Indeed, psychotic syndromes are composed of dimensions of psychopathology cutting across diagnostic boundaries. Such transdiagnostic symptom dimensions might be enhanced phenotypes to test for association with common genetic variants for Major Mental Disorders (MMDs) as summarized by Polygenic Risk Scores (PRSs) for Schizophrenia (SZ), Bipolar Disorder (BP), and Major Depressive Disorder (MDD). The objectives of this study were to: 1) identify the symptom dimension structure at First Episode Psychosis (FEP); 2) examine the extent to which MMDs PRSs explain the…

Ruolo dell'insight nell'espressività psicopatologica in un gruppo di pazienti affetti da psicosi all'esordio

Una buona capacità di insight pare costituire un fattore predittivo di minore espressività psicopatologica nei pazienti affetti da psicosi. In questo lavoro intendiamo analizzare le relazioni tra grado di insight e gravità dei sintomi psicotici utilizzando i punteggi totali e parziali ottenuti alla Positive and Negative Syndrome Scale (PANSS) in un gruppo di pazienti affetti da psicosi all'esordio nell'ambito del progetto SGAP "Sicilian Genetic and Psychosis" svolto in collaborazione con il GAP Study dell'Institute of Psychiatry, King's College of London.
