RESUMEN

Negative symptoms and cognitive deficits play a major role in psychosis and significantly influence the functional outcomes of patients, particularly those with a first episode of psychosis (FEP). However, limited research has explored the predictive capacity of cognitive deficits during FEP for subsequent negative symptomatology. Drawing from the Athens FEP research study, we conducted a retrospective longitudinal study in 80 individuals with FEP. All patients were drug naive at admission. Cognitive tests were administered at 1-month and 1-year post-admission, while negative symptomatology was assessed at the same time points using PANSS by trained raters. We considered confounding factors such as age, gender, duration of untreated psychosis (DUP), treatment received, premorbid social adjustment, and premorbid IQ. Univariate regression analysis identified cognitive domains that correlated with negative symptomatology. These, along with the confounders, were incorporated into a multiple regression, with the 1-year PANSS negative scale serving as the dependent variable. Employing the backward elimination technique, we found a statistically significant inverse relationship between the categories completed in the Wisconsin card sorting test (WCST) and the 1-year PANNS negative scale (p = 0.01), beyond the associations with DUP and the 1-month PANSS negative scale. Our results suggest that cognitive flexibility, a key component of executive functions, predicts negative symptom severity one year after FEP.

RESUMEN

Insufficiency of vitamin D levels often occur in individuals with schizophrenia and first-episode psychosis (FEP). However, it is unknown whether this represents a biological predisposition, or it is essentially driven by illness-related alterations in lifestyle habits. Lower vitamin D has also been associated with adverse neurodevelopmental outcomes and predominant negative psychotic symptoms. This study aimed to investigate the contribution of polygenic risk score for circulating 25-hydroxyvitamin D concentration (PRS-vitD) to symptom presentation among individuals with FEP enrolled in the Athens First-Episode Psychosis Research Study (AthensFEP n = 205) and the Psychosis Incident Cohort Outcome Study (PICOS n = 123). The severity of psychopathology was evaluated using the Positive and Negative Syndrome Scale at baseline and follow-up assessments (AthensFEP: 4-weeks follow-up, PICOS: 1-year follow-up). Premorbid intelligence and adjustment domains were also examined as proxy measures of neurodevelopmental deviations. An inverse association between PRS-vitD and severity of negative symptoms, in particular lack of social motivation, was detected in the AthensFEP at baseline (adjusted R2 = 0.04, p < 0.001) and follow-up (adjusted R2 = 0.03, p < 0.01). The above observation was independently validated in PICOS at follow-up (adjusted R2 = 0.06, p < 0.01). No evidence emerged for a relationship between PRS-vitD and premorbid measures of intelligence and adjustment, likely not supporting an impact of lower PRS-vitD on developmental trajectories related to psychotic illness. These findings suggest that polygenic vulnerability to reduced vitamin D impairs motivation and social interaction in individuals with FEP, thereby interventions that encourage outdoor activities and social engagement in this patient group might attenuate enduring negative symptoms.

RESUMEN

Existing literature provides extended evidence of the close relationship between stress dysregulation, environmental insults, and psychosis onset. Early stress can sensitize genetically vulnerable individuals to future stress, modifying their risk for developing psychotic phenomena. Neurobiological substrate of the aberrant stress response to hypothalamic-pituitary-adrenal axis dysregulation, disrupted inflammation processes, oxidative stress increase, gut dysbiosis, and altered brain signaling, provides mechanistic links between environmental risk factors and the development of psychotic symptoms. Early-life and later-life exposures may act directly, accumulatively, and repeatedly during critical neurodevelopmental time windows. Environmental hazards, such as pre- and perinatal complications, traumatic experiences, psychosocial stressors, and cannabis use might negatively intervene with brain developmental trajectories and disturb the balance of important stress systems, which act together with recent life events to push the individual over the threshold for the manifestation of psychosis. The current review presents the dynamic and complex relationship between stress, environment, and psychosis onset, attempting to provide an insight into potentially modifiable factors, enhancing resilience and possibly influencing individual psychosis liability.

RESUMEN

Multiple recent studies have indicated that adverse psycho-traumatic experiences are particularly significant, if not the most significant, among the environmental factors that participate in the aetiology of schizophrenic spectrum disorders. The prevalence of bullying in the adolescent population has increased dramatically compared to earlier reports. This may be related to the recent development of communication technology and the use of social media, which have expanded the means by which bullying can be practiced. The present study aims to investigate the association between bullying victimisation and psychotic symptoms in First-Episode Psychosis (FEP) patients, hypothesising that patients who have a bullying history may have increased psychotic symptoms and a more unfavourable early trajectory after treatment as usual compared to patients who do not have a bullying history. Research data were collected from a sample of men and women of the Greek general population aged between 16 and 45 (N=225) who experienced a FEP in the context of the Athens First-Episode Psychosis (FEP) Study. The assessment of bullying was performed using the Retrospective Bullying Questionnaire (RBQ). Assessment of positive and negative psychotic symptoms and general psychopathology was performed using the corresponding subscales of the Positive and Negative Syndrome Scale (PANSS) at baseline and after 4 weeks of treatment as usual. Clinical remission was assessed based on the baseline and follow-up values of the PANSS and on Andreasen's symptomatic criteria. Methodologically, Pearson's chi-square test was used to compare the history of bullying between men and women, while linear and logistic regression models were used to check the correlations between history of bullying and symptom severity at baseline and 4-week follow-up, as well as the correlation between history of bullying and remission. The prevalence of bullying history in our sample of patients (N:225) with a FEP was 51.4% (114/225). Bullying was recorded in our study participants with equal frequency in women and men. According to the analysis results, the patients who had experienced bullying did not present at baseline with significantly increased psychotic symptoms compared to the patients who did not have a history of bullying. In addition, bullying was not associated with reduced remission according to Andreasen's criteria. However, the patients who had experienced bullying were found to have significantly increased negative symptoms (B=1.66; SE=0.70; p=0.018) and increased PANSS total score (B=4.81; SE=2.34; p=0.041) at 4-week follow-up. Our results highlight the persistence of negative and overall symptoms as an impact of bullying on the development of the FEP and align with studies that support the consideration of a history of bullying during both the diagnostic and therapeutic processes.

RESUMEN

OBJECTIVES: The aim was to explore the correlations between Jumping to Conclusions (JtC) tendency and neuropsychiatric features in patients with early Parkinson's disease (PD). BACKGROUND: According to few reports, PD patients with impulsive-compulsive behaviors (ICBs) are prone to working memory difficulties including JtC bias. The correlation of psychotic features and JtC tendency remains still unclear. METHODS: Healthy controls and patients within 3 years of PD onset were recruited. Participants were examined for psychotic symptoms using a 10 question PD-specific psychosis severity scale. JtC was measured by a probalistic reasoning scenario (beads task). In PD group, medication use, motor and non-motor symptoms were documented. Impulsivity was evaluated using the Questionnaire for Impulsive-Compulsive Disorders in PD (QUIP). RESULTS: The prevalence of JtC bias was 9% (6/70) in healthy individuals, compared to 32% (22/68) of PD group [p = 0.001]. No association was detected between the presence of JtC tendency and PD-associated psychosis (p = 0.216). Patients with JtC had shorter duration of PD, more tremor-dominant PD subtype and higher QUIP scores, regardless of the dopaminergic therapy (p = 0.043, p = 0.015, p = 0.007, respectively). A trend towards attention and inhibition control deficit was noticed in JtC patients. CONCLUSIONS: We found a high prevalence of JtC bias in early, cognitively intact PD population and a potential link between subthreshold ICBs and poor performance on beads task. Additional studies are needed to confirm our results and elaborate on the mechanisms that correlate impulsivity with JtC tendency, which are likely to be different from those mediating psychotic features in early PD.

RESUMEN

INTRODUCTION: Clinical insight constitutes a useful marker of the progress and outcome of the First Episode of Psychosis (FEP), and lack of insight has been associated with more severe psychopathology, treatment non-adherence, and rehospitalization/relapse. In this study, we aimed to further investigate the possible role of insight as a predictor of relapse, its relation to diagnosis, and other parameters of positive psychotic symptomatology (delusions, hallucinations, and suspiciousness). METHODS: The Athens FEP study employed a prospective, longitudinal cohort design in which consecutive newly diagnosed patients with psychosis were interviewed and asked to voluntarily participate after completing informed consent. A total of 88/225 patients were examined at three different time points (baseline, month, and year). Their scores in the relevant items of the Positive and Negative Syndrome Scale (PANSS) were compared (G12 for insight, P1 for delusions, P3 for hallucinations, and P6 for suspiciousness), and they were further associated to diagnosis and the outcome at the end of the year (remission/relapse). RESULTS: In total, 22/88 patients with relapse at the year had greater scores in G12 for both the month and the year, and this finding was corroborated after adjusting the statistical analysis for demographics, diagnosis, social environment, and depression via multiple logistic regression analysis. Moreover, delusions and suspiciousness were significantly higher in patients diagnosed with non-affective psychosis compared to those diagnosed with affective psychosis (p < 0.001) at the first month. CONCLUSIONS: Lack of insight at the first month may serve as a predictor of relapse at the year.

RESUMEN

BACKGROUND: Evidence suggests that environmental factors not only increase psychosis liability but also influence the prognosis and outcomes of psychotic disorders. We investigated temporal and cross-sectional associations of a weighted score of cumulative environmental liability for schizophrenia - the exposome score for schizophrenia (ES-SCZ) - with functioning in first-episode psychosis (FEP). METHODS: Data were derived from the baseline and 1-month assessments of the Athens FEP Research Study that enrolled 225 individuals with FEP. The Global Assessment of Functioning (GAF) and the Personal and Social Performance Scale (PSP) were used to measure social, occupational, and psychological functioning. The ES-SCZ was calculated based on the previously validated method. RESULTS: ES-SCZ was associated with the total scores of GAF and PSP at baseline and 1-month assessments. These findings remained significant when accounting for several associated alternative explanatory variables, including other environmental factors (obstetric complications, migration, ethnic minority), clinical characteristics (duration of untreated psychosis, symptom severity, previous antipsychotic use), and family history of psychosis, demonstrating that the association between ES-SCZ and functioning is over and above other risk factors and cannot be explained by symptom severity alone. Functioning improved from baseline to 1-month assessment, but no significant ES-SCZ-by-time interaction was found on functioning, indicating that functioning changes were not contingent on ES-SCZ. CONCLUSIONS: Our findings suggest that rather than a predictor of functional improvement, ES-SCZ represents a stable severity indicator that captures poor functioning in early psychosis. Environmental risk loading for schizophrenia (ES-SCZ) can be beneficial for clinical characterization and incorporated into transdiagnostic staging models.

RESUMEN

First Episode Psychosis (FEP) emergence and clinical outcome might be attributed to various parameters, wherein gene - environment interaction plays a pivotal role in. Four specified psychometric tools, that have been used for the evaluation of possible environmental, social and psychological parameters involved in the etiopathology and clinical course of psychosis are the following: Social Environment Assessment Tool (SEAT), Discrimination (DISC), Brief Core-Schema Scales (BCSS) and Life-Threatening Events-Brief Life-Events Questionnaire (LTE-Q). These tools were used in the Athens-FEP Study assessment schedule, which investigates the gene-environment interaction among patients presenting with FEP. The goal of the present study is to present them in regard to their content, their use in international literature, their translation in Greek, and their test-retest reliability. SEAT, DISC and BCSS were provided to the Athens FEP Study by the European Network of National Schizophrenia Network studying Gene-Environment interactions (EUGEI) research project. LTE-Q was already translated into Greek and was selected as befitting the purposes of the FEP-Study. The EUGEI instruments were translated into Greek language by two independent translators for each instrument. All translators were qualified in the administration of the English version of the scales after being trained online through a comprehensive work-package training set provided by the EUGEI. The principal investigator of the Athens-FEP project checked and approved the final versions of the questionnaires. The four tools were administered to 32 subjects, all diagnosed with FEP, participating in the Athens-FEP project. Intraclass correlation coefficients (ICCs) were used to assess the agreement between scores of the four questionnaires after first and second administration. The scales were administered to our subjects twice, with an intermediate period of three weeks between the first and second administrations, by three qualified researchers. There was a statistically significant agreement for almost all measurements of the four questionnaires, except for the frequency dimension of DISC. Agreement between those measurements was very high (ICCs>0.8). Our study is an indication that the Greek versions of the psychometric tools are reliable, although a more thorough test of their psychometric properties is needed. All four questionnaires have unique properties that differentiate them from other similar tools. Moreover, the DISC is the only discrimination scale translated into Greek. More importantly, the translated questionnaires are part of a broad, well-established research package of psychometric tools, suitable for the evaluation of environmental risk factors potentially involved in early psychosis, which might represent a valuable scientific resource in the Greek research field.

RESUMEN

Exposure to traumatic life events is one of the most robust predictors for psychosis. The Childhood Trauma Questionnaire-Short Form (CTQ-SF), a version of Childhood Experience of Care and Abuse (CECAEUGEI) and a version of the Bullying Questionnaire (BQEUGEI) refer to early life adversities, traumatic episodes and bullying. Those scales belong to a battery of psychometric tools detecting environmental and genetic factors associated with First Episode Psychosis (FEP) that was employed in the Athens-FEP study. The goal of this paper is to present those three versions, regarding their content, their use in the international research, their translation in Greek and their test-retest reliability. The three questionnaires were translated by two independent translators, administered twice to 32 subjects with FEP, with a three weeks intermediate period. Intraclass correlation coefficients (ICCs) were used to investigate agreement between scores of the first and second administration. There was a statistically significant agreement for all measurements of the three questionnaires. Cronbach's a were also calculated and were acceptable and over 0.7. Our study is an indication that the translated versions are reliable, although a more thorough test of their psychometric properties is needed. Both might be used in the Greek research field as part of a broad package of psychometric tools, specifically addressed to patients with FEP.

RESUMEN

BACKGROUND: Early Intervention Services (EIS) aim to reduce relapse rates and achieve better treatment and functional outcomes for first episode psychosis (FEP) patients. Existing models of services in Greece are still treatment as usual (TAU), however a reform of mental health services is underway and initial steps have been taken to shift standard care towards EIS. The purpose of the study is to address therapeutic gaps by exploring service engagement and relapse rates in the current standard care model for psychosis. METHODS: We examined follow-up and relapse rates one year after initial treatment contact in the first longitudinal FEP study conducted in Greece. 225 patients were enrolled between 2015-2020. Sociodemographic, clinical and functional characteristics were assessed in association with follow-up and relapse rates. RESULTS: Within a TAU follow-up setting, one year attrition rates were high. Only 87 patients (38,7%) retained contact with services after one year and within this time frame, 19 of them (21,8%) experienced a severe relapse requiring rehospitalization. Demographic, clinical and functional contributors failed to predict service engagement and relapse rates, with the exception of treatment adherence. CONCLUSION: Both follow-up and one-year rehospitalization rates in our FEP sample, highlight the need for the implementation of early intervention services, that will aim at engagement maximization and relapse prevention. These indexes also provide a benchmark against which future early intervention services for psychosis in Greece will have to demonstrate superior efficacy.

RESUMEN

Several studies have examined the impact of the COVID-19 pandemic on healthcare workers' mental health, but only a few have investigated its detrimental effect on the mental well-being of mental health workers (MHWs). BACKGROUND: The current study aimed to explore the effect of the fear of COVID-19 (FCV-19) on professional quality of life dimensions, namely compassion satisfaction (CS), burnout (BO), and secondary traumatic stress (STS) in MHWs above and beyond sociodemographic and professional factors. METHODS: Hierarchical linear regression models were employed to examine the relationship of extreme FCV-19 with CS, BO, and STS in MHWs (n = 224), after considering sociodemographic variables as potential confounding factors. Extreme FCV-19 was operationalized as a binary variable with a cut-off score of ≥16.5 considered as extreme fear. RESULTS: We found that extreme FCV-19 in MHWs is linked with increased compassion fatigue (BO and STS), and this relationship is exacerbated by younger age in regard to BO and by female gender concerning STS. CS remains unaffected by severe FCV-19, and it is higher in older participants. CONCLUSION: Organizational support is required to protect MHWs' mental well-being and ensure the quality of care they provide during prolonged crises, such as the COVID-19 pandemic. Measures that intensify a sense of safety, protection, and control against COVID-19 infections in mental health services should be included in the recommendations that may reduce BO and STS among MHWs.

RESUMEN

The Tobacco and Alcohol Questionnaire (TAQ) and the Cannabis Experience Questionnaire (CEQ) are two instruments employed in the evaluation of substance use. The First Episode Psychosis (FEP) study in Athens employed two versions of those questionnaires, as part of a battery of psychometric tools, detecting environmental and genetic factors associated with FEP and addressed specifically to the distinctive characteristics of patients with FEP. The goal of the present study is to present those two versions, regarding their content, their use in international research, their translation in Greek, and their test-retest reliability. The two questionnaires were translated by two independent translators and administered to 32 subjects with FEP twice, in order to be tested for test-retest reliability. Cohen's kappa was used to measure agreement between qualitative variables and ICC between quantitative variables. Significant agreement was found between the two measurements in all items of the TAQ version and almost all items of the CEQ version. Our study is an indication that both translations are reliable, although a more thorough test of their psychometric properties is needed. Both might be used in the Greek research field as part of a broad package of psychometric tools, specifically addressed to patients with FEP.

RESUMEN

BACKGROUND: Validated clinical prediction models of short-term remission in psychosis are lacking. Our aim was to develop a clinical prediction model aimed at predicting 4-6-week remission following a first episode of psychosis. METHOD: Baseline clinical data from the Athens First Episode Research Study was used to develop a Support Vector Machine prediction model of 4-week symptom remission in first-episode psychosis patients using repeated nested cross-validation. This model was further tested to predict 6-week remission in a sample of two independent, consecutive Danish first-episode cohorts. RESULTS: Of the 179 participants in Athens, 120 were male with an average age of 25.8 years and average duration of untreated psychosis of 32.8 weeks. 62.9% were antipsychotic-naïve. Fifty-seven percent attained remission after 4 weeks. In the Danish cohort, 31% attained remission. Eleven clinical scale items were selected in the Athens 4-week remission cohort. These included the Duration of Untreated Psychosis, Personal and Social Performance Scale, Global Assessment of Functioning and eight items from the Positive and Negative Syndrome Scale. This model significantly predicted 4-week remission status (area under the receiver operator characteristic curve (ROC-AUC) = 71.45, P < .0001). It also predicted 6-week remission status in the Danish cohort (ROC-AUC = 67.74, P < .0001), demonstrating reliability. CONCLUSIONS: Using items from common and validated clinical scales, our model significantly predicted early remission in patients with first-episode psychosis. Although replicated in an independent cohort, forward testing between machine learning models and clinicians' assessment should be undertaken to evaluate the possible utility as a routine clinical tool.

RESUMEN

It is suggested that Jumping To Conclusions (JTC) reasoning bias might contribute to the distortion of external reality. However, the association between psychotic manifestations and JTC is obscure, especially if general intelligence is considered as a mediator. The aim of this study is to investigate the relation between severity, early clinical improvement and remission of symptoms in First Episode Psychosis (FEP) with JTC as an explanatory factor. One hundred seventy-one FEP individuals were evaluated with the Positive and Negative Syndrome Scale (PANSS) at baseline and one month after treatment initiation. Clinical improvement was ascribed as symptom change one-month post-baseline measurements. Symptomatic remission was assessed with the Andreasen severity criteria and JTC with the Beads Task, operationalized through Draws To Decision (DTD) (the lower the number of DTD, the higher the JTC bias). Regarding symptoms severity, total psychotic, total positive psychotic, and hallucinations-item PANSS scores showed a negative association with JTC after controlling for IQ. Regarding early clinical improvement, the association with JTC was non-significant. No significant association was detected between one month remission status of FEP and JTC. Our findings indicate that severity of positive symptoms is not associated with hastiness in decision-making, but rather with a heightened conservatism in terms of increased data gathering. Further research is required to replicate the results and clarify the cognitive processes involved.

RESUMEN

BACKGROUND: Subjective quality of life (SQOL) in people with borderline personality disorder (BPD) is a marker of disease burden; a crucial treatment outcome; an indicator of psychosocial functioning; and a measure of interventions' effectiveness. Given the dearth of consolidated data, the current study examined psychopathological determinants of global and domain-specific SQOL in people with BPD. METHODS: Hierarchical regression models were employed to examine in BPD patients (n = 150) the relationships of the number of BPD diagnostic criteria; the co-occurrence of other personality disorders (PDs); depression; state and trait anxiety; suicidality; self-harming; alcohol and substance use disorders with SQOL indices, namely physical health, psychological health, social relationships, environment, overall QOL and overall health. SQOL was estimated using the WHOQOL-BREF instrument. RESULTS: Co-existing symptomatology such as depression, state and trait anxiety, and personality pathology, namely the co-occurrence of other PDs, exhibited significant associations with global and domain-specific SQOL, albeit depression was the strongest determinant of the most SQOL domains. In contrast, the number of BPD diagnostic criteria and central illness features such as suicidality, self-harming behaviour, and impulsivity manifested through alcohol and substance use did not exhibit significant associations with any SQOL dimension. CONCLUSIONS: Comprehensive assessment of depressive symptoms should be regularly implemented in BPD services to facilitate early detection and treatment, thereby ensuring patients' SQOL. Accordingly, tackling anxiety and other PDs co-occurrence through appropriate interventions can facilitate more effectively SQOL improvement. Our findings can be explained by the hypothesis that co-existing psychopathology such as depression, anxiety and co-occurrence of other PDs in BPD patients represent illness severity indices rather than comorbid disorders, and might fully mediate the effect of BPD traits on SQOL. Future mediation analysis is required to elucidate this hypothesis.

RESUMEN

BACKGROUND: Co-occurring psychiatric disorders in adults with Attention Deficit Hyperactivity Disorder (ADHD) and/or Autism Spectrum Disorder (ASD) contribute to the burden of the healthcare and possibly to the delay of diagnosis. Aim of the study was to clinically assess the prevalence and compare lifetime co-occurring psychopathology in a sample of newly diagnosed ADHD and/or ASD adults and discuss the diagnostic challenges they pose. METHODS: The lifetime prevalence rates of ten of the most frequently co-occurring psychiatric diagnoses was registered in 336 adults of normal intelligence who underwent a thorough clinical evaluation for the diagnosis of ADHD and/or ASD for the first time in their lives. Four study groups were formed: the ADHD (n = 151), the ASD (n = 58), the ADHD+ASD (n = 28) and the nonADHD/nonASD (NN) (n = 88) group. RESULTS: At least one co-occurring psychopathology was found in 72.8% of the ADHD group, in 50% of the ASD group, in 72.4% of the ADHD+ASD group and in 76.1% of the NN group (p = 0.004). In all groups the most frequent psychiatric disorder was depressive disorder. The only significant difference regarding the patterns of psychiatric co-occurrence between the ADHD and the nonADHD groups (ASD and NN groups) was found for SUD (p = 0.001). Also, the proportion of subjects with Bipolar Disorder was significantly greater in the NN group as compared to those with ASD (p = 0.025). CONCLUSIONS: Our results support the high prevalence of co-occurring psychiatric disorders in adults with ADHD and/or ASD with the ASD group presenting the lowest rate. The most marked difference between the ADHD and the nonADHD groups was found for SUD. Moreover, our findings highlight the need for a thorough clinical assessment of all referred patients both in the presence and absence of ADHD and/or ASD.

RESUMEN

BACKGROUND: Premorbid adjustment (PA) abnormalities in psychotic disorders are associated with an earlier age at onset (AAO) and unfavorable clinical outcomes, including treatment resistance. Prior family studies suggest that familial liability, likely reflecting increased genetic risk, and socioeconomic status (SES) contribute to premorbid maladjustment. However, their joint effect possibly indicating gene-environment interaction has not been evaluated. METHODS: We examined whether family history of psychosis (FHP) and parental SES may predict PA and AAO in unrelated cases with first-episode psychosis (n = 108) and schizophrenia (n = 104). Premorbid academic and social functioning domains during childhood and early adolescence were retrospectively assessed. Regression analyses were performed to investigate main effects of FHP and parental SES, as well as their interaction. The relationships between PA, AAO, and response to antipsychotic medication were also explored. RESULTS: Positive FHP associated with academic PA difficulties and importantly interacted with parental SES to moderate social PA during childhood (interaction p = 0.024). Positive FHP and parental SES did not predict differences in AAO. Nevertheless, an earlier AAO was observed among cases with worse social PA in childhood (ß = -0.20; p = 0.005) and early adolescence (ß = -0.19; p = 0.007). Further, confirming evidence emerged for an association between deficient childhood social PA and poor treatment response (p = 0.04). CONCLUSIONS: Familial risk for psychosis may interact with parental socioeconomic position influencing social PA in childhood. In addition, this study supports the link between social PA deviations, early psychosis onset, and treatment resistance, which highlights premorbid social functioning as a promising clinical indicator.

RESUMEN

AIMS: Athens First-Episode Psychosis (FEP) Research study, aims to explore the potential associations between multiple genetic, environmental and neurometabolic risk factors of psychotic disorders, through the clinical management of FEP patients with minimal exposure (<2 weeks) to antipsychotic treatment at entry. The goal of this paper is to introduce the background, rationale and design of the study and present its preliminary findings. METHODS: We developed a longitudinal cohort study of FEP patients 16-45 years old, presenting at the emergency units of five psychiatric hospitals across Athens, Greece. Research timeline includes baseline, 1-month and 1-year follow-up. Clinical, genetic, environmental, cognitive and biochemical parameters are measured, using psychometric tools, clinical interviews and laboratory tests. A descriptive analysis of baseline and 1-month assessments was performed including demographic characteristics, family history, medication, clinical picture, traumatic experiences, drug use and cognitive functioning. RESULTS: During the last 3 years, 130 subjects have been enrolled in the study. Data so far reveal that, despite the severity of baseline presentation, at 1-month the majority (57.4%) met the Andreasen symptom severity criteria for remission, without the time criterion and showed mild functional improvement. Several environmental adversities and poor cognitive performance were identified, which need to be further elaborated. CONCLUSIONS: Athens FEP Research study is the first gene-environment interaction study in Greece. In this article we introduce the organization and methodological framework of the project, along with its basic initial findings. Future analysis will allow the validation of tractable predictors and risk factors implicated in the development and outcome of psychosis.

RESUMEN

To present the 3-year experience of the early intervention in psychosis (EIP) service implementation of the 1st Psychiatric University Clinic in Athens. An overview of: (1) the purpose of our service, (2) the referral network, (3) the selection criteria, (4) the diagnostic procedures, (5) the therapeutic interventions and (6) the research activities. The service was established in 2012 and developed gradually aiming to provide information, early detection, treatment and support to people aged 15 to 40 years with psychotic manifestations, who are either at increased risk of developing psychosis (at-risk mental state [ARMS]) or with first episode psychosis (FEP). In order to assess individuals with ARMS, we used the comprehensive assessment of at-risk mental states interview and the Social and Occupational Functioning Assessment Scale The duration of untreated psychosis was estimated by using the Nottingham Onset Schedule. So far we have had 65 referrals, of which 26 were ARMS and 17 FEP. Based on the individual needs, they were offered psychotherapeutic and/or pharmacological treatment. After 3 years, the rate of transition to psychosis was 19.2% and the rate of psychosis relapse was 11.7%. The implementation of our service has had positive results, enabling young people with early psychosis to receive prompt and effective care. The rates of transition to psychosis are the first to be published from a Greek EIP service. Further development of our referral network and inter-hospital collaboration will allow us to address the needs of a wider part of the population.
