Savoxepine: invalidation of an "atypical" neuroleptic response pattern predicted by animal models in an open clinical trial with schizophrenic patien…
1991
The new tetracyclic compound savoxepine exhibits potent antidopaminergic effects with preferential activity in the hippocampus as compared to striatum in rat brain. As a result of behavioural animal models and regional differences in dopamine receptor binding characteristics, it has been suggested to possess an "atypical" neuroleptic response pattern. In an open clinical trial, savoxepine was administered to 12 in-patients suffering from paranoid schizophrenia and schizophreniform disorder (DSM-III). Eight patients were treated with a stable dose of 0.5 mg per day throughout the study, while in the remaining patients higher doses up to 20 mg/day were administered. Mean total BPRS scores and…
Two-year outcome in first-episode psychosis treated according to an integrated model. Is immediate neuroleptisation always needed?
2000
SummaryIn this multicentre study the two-year outcome of two groups of consecutive patients (total N = 106) with first-episode functional non-affective psychosis, both treated according to the ‘need-specific Finnish model’, which stresses teamwork, patient and family participation and basic psychotherapeutic attitudes, was compared. No alternative treatment facilities were available in the study sites. The two study groups differed in the use of neuroleptics: three of the sites (the experimental group) used a minimal neuroleptic regime whilst the other three (the control group) used neuroleptics according to the usual practice. Total time spent in hospital, occurrence of psychotic symptoms …
Early developmental milestones in adult schizophrenia and other psychoses. A 31-year follow-up of the Northern Finland 1966 Birth Cohort
2001
Abstract Delayed childhood development may precede adult psychoses. We tested this hypothesis in a large, general population birth cohort (n=12 058) followed to age 31 years. The ages at which individuals learned to stand, walk, speak, and became potty-trained (bowel control) and dry (bladder control), were recorded at a 1-year examination. Psychiatric outcome was ascertained through linkage to a national hospital discharge register. Cumulative incidence of DSM-III-R schizophrenia, other psychoses and non-psychotic disorders were stratified according to the timing of milestones and compared within the cohort using internal standardization. 100 cases of DSM-III-R schizophrenia, 55 other psyc…
Prediction of acute clinical response following a first episode of non affective psychosis: results of a cohort of 375 patients from the Spanish PAFI…
2013
Abstract Objective Predicting response to antipsychotic treatment might optimize treatment strategies in early phases of schizophrenia. We aimed to investigate sociodemographic, premorbid and clinical predictors of response to antipsychotic treatment after a first episode of non-affective psychosis. Method 375 (216 males) patients with a diagnosis of non affective psychosis entered the study. The main outcome measure was clinical response at 6 weeks and variables at baseline were evaluated as predictors of response. ANOVA for continuous and chi-square for categorical data were used to compare responders and non-responders. Multivariate logistic regression was used to establish a prediction …
Three dimensions of depression in patients with acute psychotic disorders: A replication study
1999
Depressive symptoms in psychotic disorders are of high relevance but seem to be heterogeneous when assessed with a standard rating scale. The present analysis is a replication study on the dimensionality of the Bech-Rafaelsen Melancholia Scale (BRMES) in acutely psychotic patients with substantial depression defined according to a functional approach across the nosological borders of schizophrenia with major affective symptoms, schizoaffective disorder, depressed subtype, and major depression with psychotic features. The baseline data of 123 patients participating in a multicenter pharmacological trial were evaluated with structural equation models. A previously reported three-dimensional m…
Suicidal behaviour in first-episode non-affective psychosis: Specific risk periods and stage-related factors
2014
Suicide is a major cause of premature death in psychosis. Earlier stages have been associated with higher risk. However, such risk periods have not been specifically determined and risk factors for suicidal behaviour may change over those periods, which may have crucial implications for suicide prevention. The aim of this study was to determine and characterize the highest risk period for suicide in a representative sample of first-episode psychosis (FEP) patients. Suicidal behaviour prior to first presentation of psychosis and during a 3-year follow-up was examined in a sample of 397 individuals. Risk factors for suicidal behaviour during specific time periods were investigated and compare…
Tobacco smoking and nicotine dependence in first episode and established psychosis
2019
Aim\ud People with psychotic disorders have increased premature mortality in comparison with the general population, with high rates of cigarette use a contributing factor. We aimed to describe the prevalence of cigarette use and nicotine dependence (ND) in first episode psychosis (FEP), and established psychosis; and to investigate associations between clinical symptoms and ND.\ud \ud Methodology\ud Smoking and clinical data were collected from two cohorts: 181 people with FEP recruited as part of the Physical Health and Substance Use Measures in First Onset Psychosis (PUMP) study and from 432 people with established psychosis recruited as part of the Improving\ud physical health and reduc…
Motor abnormalities and basal ganglia in first-episode psychosis (FEP)
2020
AbstractBackgroundMotor abnormalities (MAs) are the primary manifestations of schizophrenia. However, the extent to which MAs are related to alterations of subcortical structures remains understudied.MethodsWe aimed to investigate the associations of MAs and basal ganglia abnormalities in first-episode psychosis (FEP) and healthy controls. Magnetic resonance imaging was performed on 48 right-handed FEP and 23 age-, gender-, handedness-, and educational attainment-matched controls, to obtain basal ganglia shape analysis, diffusion tensor imaging techniques (fractional anisotropy and mean diffusivity), and relaxometry (R2*) to estimate iron load. A comprehensive motor battery was applied incl…
Specific executive/attentional deficits in patients with schizophrenia or bipolar disorder who have a positive family history of psychosis
2003
Neurocognitive impairments are well documented in patients with schizophrenia and their healthy first-degree biological relatives. Less is known about neuropsychological performance in bipolar disorders, but some studies indicate that, compared to schizophrenia, bipolar disorder displays a similar profile pattern with less severe deficits. The genetic and environmental contributions to the development of neurocognitive deficits are also unclear. This study explored the effect of a family history (FH) of psychotic disorders in first-degree relatives on a variety of cognitive domains (abstraction and flexibility, verbal fluency, verbal memory, motor activity and visual-motor processing/attent…
Cognitive impairment in schizoaffective disorder: a comparison with non-psychotic bipolar and healthy subjects.
2007
Objective: Only a few studies have examined specifically the neuropsychological performance of schizoaffective patients. Method: The sample consisted of 34 euthymic DSM-IV schizoaffective patients, who were compared with 41 euthymic bipolar patients without history of psychotic symptoms and 35 healthy controls. Euthymia was defined by a score of 6 or less at the Young Mania Rating Scale and a score of 8 or less at the Hamilton Depression Rating Scale for at least 6 months. Patients were compared with several clinical, occupational, and neuropsychological variables such as executive function, attention, verbal and visual memory and the two groups were contrasted with 35 healthy controls on…
