Duration of untreated psychosis and its correlates in first-episode psychosis in Finland and Spain
2002
Kalla O, Aaltonen J, Wahlstrom J, Lehtinen V, Garcia Cabeza I, Gonzalez de Chavez M. Duration of untreated psychosis and its correlates in first-episode psychosis in Finland and Spain. Acta Psychiatr Scand 2002: 106: 265–275. © Blackwell Munksgaard 2002. Objective: To examine the association of duration of untreated psychosis (DUP) with early course characteristics in first-episode psychosis in Finland and Spain. Method: Eighty-six patients from Finland (49) and Spain (37) were evaluated on various early course characteristics. Results: The mean value of DUP was 4.0 months (median 2 months) for the Finnish patients and 9.9 months (median 2 months) for the Spanish ones. In both groups, long …
Schizophrenia polygenic risk score and cannabis use modify psychosis expression in first episode psychosis patients and population controls
2019
AbstractBackgroundDiagnostic categories within the psychosis spectrum are widely used in clinical practice, however psychosis may occur on a continuum. Therefore, we explored whether the continuous distribution of psychotic symptoms across categories is a function of genetic as well as environmental risk factors, such as polygenic risk scores (PRSs) and cannabis use.MethodsAs part of the EU-GEI study, we genotyped first episode psychosis patients (FEP) and population controls, for whom transdiagnostic dimensions of psychotic symptoms or experiences were generated using item response bi-factor modelling. Linear regression was used, separately in patients and controls, to test the association…
Cannabis-associated symptom profiles in patients with first episode psychosis and population controls
2019
AbstractObjectiveThe evidence is mixed on whether cannabis use is associated with a particular symptomatology in first episode psychosis (FEP) patients.The authors set out to investigate a) patterns of association between cannabis use and transdiagnostic symptom dimensions; b) whether the extent of use of cannabis contributes to the variation in clinical and subclinical symptom profiles.MethodThe authors analysed data from 901 patients and 1235 controls recruited across six countries, as part of the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. Item response modelling was used to estimate two bifactor models, which included genera…
On Jacques Lacan Psychosis Theory and ERPs Analysis
2012
If properly interpreted, some recent neurolinguistic researches based on the so-called Event-Related Potentials (ERPs) and conducted on patients showing schizophrenic spectrum disorders, seem to confirm the main Jacques Lacan theses on psychosis. In this brief note, we simply want put to the attention the existence of this possible and interesting correlation.
First-Episode Psychotic Patients Showed Longitudinal Brain Changes Using fMRI With an Emotional Auditory Paradigm
2020
Most previous longitudinal studies of functional magnetic resonance imaging (fMRI) in first-episode psychosis (FEP) using cognitive paradigm task found an increased activation after antipsychotic medications. We designed an emotional auditory paradigm to explore brain activation during emotional and nonemotional word processing. This study aimed to analyze if longitudinal changes in brain fMRI BOLD activation is present in patients vs. healthy controls. A group of FEP patients (n = 34) received clinical assessment and had a fMRI scan at baseline and follow-up (average, 25-month interval). During the fMRI scan, both emotional and nonemotional words were presented as a block design. Results w…

INCIDENCE OF PSYCHOTIC DISORDERS IN PALERMO: PRELIMINARY DATA
2012
Background: The incidence of psychotic disorders varies in different geographical areas (McGrath 2004). Recent data suggest that the incidence is higher in males, migrant minorities and in urban areas. There aren’t many available epidemiological data on the incidence of psychotic disorders in Italy. This is the first incidence study on psychotic disorders carried out in Palermo, the capital of Sicily. Methods: we screened all patients presenting with their first episode of psychosis to the mental health services of our catchment area (5 inpatient, 5 outpatient units and 3 private psychiatric hospitals) over a period of three years (2008-2011). The diagnosis of psychosis was defined using th…
Subtypes of panic attacks and ICD-9 classification.
1986
No single ICD-9 category corresponds to panic disorder (DSM-III). To investigate whether patients with panic attacks can be identified by means of ICD-9, 97 patients with three panic attacks within 3 weeks were recruited from various medical centers, and were classified independently according to DSM-III and ICD-9. The ICD-9 diagnoses were scattered over a broad range of categories, and it was impossible to identify patients with panic disorder in this manner. Anxiety state, affective psychosis, and depressive neurosis were the most frequent ICD-9 diagnoses. The boundary between affective psychosis on the one hand and anxiety state and depressive neurosis on the other hand was validated by …
