OBJECTIVE: The study assessed the level of reintegration into the community of patients with schizophrenia in Oslo, Norway, a country with a well-developed social welfare system and low unemployment rates. METHODS: Eighty-one patients with a DSM-III-R diagnosis of schizophrenia treated in 1980 and in 1983 in a short-term ward of a psychiatric hospital were followed up after seven years. Seventy-four of 76 patients alive at follow-up agreed to participate. Social functioning was measured by the Strauss-Carpenter Level of Functioning Scale and the Social Adjustment Scale. RESULTS: At follow-up 78 percent of patients lived independently, 47 percent were socially isolated, and 94 percent were unemployed. Thirty-four percent had lost employment in the follow-up period. A poor outcome in terms of social functioning and community reintegration was associated with loss of employment. A good outcome was predicted by short periods of inpatient hospitalization, high levels of education, being married, male gender, and not having a late onset of psychosis. CONCLUSIONS: The level of homelessness among these patients with schizophrenia was encouragingly low, which may have been expected in a high-income welfare society. However, insufficient efforts were aimed at social and instrumental rehabilitation, and the level of unemployment was alarmingly high.
Eighty-eight patients were admitted to the acute ward of a catchment area suffering from the following functional psychoses: schizophrenia (S; n = 41), affective disorder (AD; n = 22), other disorders (OD; n = 25). Follow-up data were obtained for 97%. Ten patients were dead at follow-up, 8 due to suicide. Sixty-five were personally interviewed. While nearly all the patients had only brief periods of rehospitalization, most had used neuroleptics during the follow-up period. Compared to other samples, functioning at follow-up was fairly good for the AD and OD patients, but rather poor for the S patients.
The reorganization in 1981 of a general hospital psychiatric ward in Oslo, Norway, to achieve a more suitable treatment milieu for patients with schizophrenia resulted in a change in patients' perceptions of the ward atmosphere. Reduced group participation and increased individualized support from staff led patients to perceive of the ward as having a low level of anger and aggression and a high level of order and organization. This study examined whether the reorganization was associated with improved treatment outcome.
Psychiatrists retrospectively examined the charts of all patients with a DSM-III-R diagnosis of schizophrenia or schizophreniform disorder who were admitted to the ward the year before and the second year after the reorganization. Multiple regression analyses were used to examine treatment outcomes for both groups. Outcome was measured indirectly by length of stay, level of functioning at discharge, and whether the patient was rehospitalized during the following seven years.
Patients treated after the reorganization had significantly shorter stays with no reductions in either level of functioning at discharge or length of community tenure after discharge. Differences in demographic characteristics, illness history, or psychopharmacological treatment could not account for differences in outcome.
The results supported the hypothesis that the organization and milieu of brief-stay wards influence the short-term outcome of inpatient treatment of patients with schizophrenia.
Ethnic minority status and childhood trauma are established risk factors for psychotic disorders. Both are found to be associated with increased level of positive symptoms, in particular auditory hallucinations. Our main aim was to investigate the experience and effect of childhood trauma in patients with psychosis from ethnic minorities, hypothesizing that they would report more childhood trauma than the majority and that this would be associated with more current and lifetime hallucinations.
In this cross-sectional study we included 454 patients with a SCID-I DSM-IV diagnosis of non-affective or affective psychotic disorder. Current hallucinations were measured with the Positive and Negative Syndrome Scale (P3; Hallucinatory Behaviour). Lifetime hallucinations were assessed with the SCID-I items: auditory hallucinations, voices commenting and two or more voices conversing. Childhood trauma was assessed with the Childhood Trauma Questionnaire, self-report version.
Patients from ethnic minority groups (n = 69) reported significantly more childhood trauma, specifically physical abuse/neglect, and sexual abuse. They had significantly more current hallucinatory behaviour and lifetime symptoms of hearing two or more voices conversing. Regression analyses revealed that the presence of childhood trauma mediated the association between ethnic minorities and hallucinations.
More childhood trauma in ethnic minorities with psychosis may partially explain findings of more positive symptoms, especially hallucinations, in this group. The association between childhood trauma and these first-rank symptoms may in part explain this group's higher risk of being diagnosed with a schizophrenia-spectrum diagnosis. The findings show the importance of childhood trauma in symptom development in psychosis.
Sleep problems in bipolar disorder (BD) are common, but reported rates vary from 10% to 80%, depending on definitions, methodologies and management of potential confounding factors. This multicenter study seeks to address these issues and also compares BD cases with Hypersomnia as well as the more commonly investigated Insomnia and No Sleep Problem groups.
A cross-sectional comparison of sleep profiles in 563 BD I and II individuals who participated in a structured assessment of demographic, clinical, illness history and treatment variables.
Over 40% cases met criteria for Insomnia and 29% for Hypersomnia. In univariate analysis, Insomnia was associated with BD II depression whilst Hypersomnia was associated with BD I depression or euthymia. After controlling for confounders and covariates, it was demonstrated that Hypersomnia cases were significantly more likely to be younger, have BD I and be prescribed antidepressants whilst Insomnia cases had longer illness durations and were more likely to be prescribed benzodiazepines and hypnotics.
Whilst Insomnia symptoms are common in BD, Hypersomnia is a significant, frequently underexplored problem. Detailed analyses of large representative clinical samples are critical to extending our knowledge of differences between subgroups defined by sleep profile.
Pre- and perinatal adversities may increase the risk for schizophrenia and bipolar disorder. Hypoxia-related obstetric complications (OCs) are associated with brain anatomical abnormalities in schizophrenia, but their association with brain anatomy variation in bipolar disorder is unknown.
Magnetic resonance imaging brain scans, clinical examinations and data from the Medical Birth Registry of Norway were obtained for 219 adults, including 79 patients with a DSM-IV diagnosis of bipolar disorder (age 29.4 years, s.d. = 11.8 years, 39% male) and 140 healthy controls (age 30.8 years, s.d. = 12.0 years, 53% male). Severe hypoxia-related OCs throughout pregnancy/birth and perinatal asphyxia were each studied in relation to a priori selected brain volumes (hippocampus, lateral ventricles and amygdala, obtained with FreeSurfer), using linear regression models covarying for age, sex, medication use and intracranial volume. Multiple comparison adjustment was applied.
Perinatal asphyxia was associated with smaller left amygdala volume (t = -2.59, p = 0.012) in bipolar disorder patients, but not in healthy controls. Patients with psychotic bipolar disorder showed distinct associations between perinatal asphyxia and smaller left amygdala volume (t = -2.69, p = 0.010), whereas patients with non-psychotic bipolar disorder showed smaller right hippocampal volumes related to both perinatal asphyxia (t = -2.60, p = 0.015) and severe OCs (t = -3.25, p = 0.003). No associations between asphyxia or severe OCs and the lateral ventricles were found.
Pre- and perinatal hypoxia-related OCs are related to brain morphometry in bipolar disorder in adulthood, with specific patterns in patients with psychotic versus non-psychotic illness.
To describe 1-year outcome in a large clinical epidemiologic sample of first-episode psychosis and its predictors.
A total of 301 patients with first-episode psychosis from four healthcare sectors in Norway and Denmark receiving common assessments and standardized treatment were evaluated at baseline, at 3 months, and at 1 year.
Substantial clinical and social improvements occurred within the first 3 months. At 1-year 66% were in remission, 11% in relapse, and 23% continuously psychotic. Female gender and better premorbid functioning were predictive of less severe negative symptoms. Shorter DUP was predictive for shorter time to remission, stable remission, less severe positive symptoms, and better social functioning. Female gender, better premorbid social functioning and more education also contributed to a better social functioning.
This first-episode sample, being well treated, may be typical of the early course of schizophrenia in contemporary centers.
Previous studies of bipolar disorders indicate that childhood abuse and substance abuse are associated with the disorder. Whether both influence the clinical picture, or if one is mediating the association of the other, has not previously been investigated.
A total of 587 patients with bipolar disorders were recruited from Norway and France. A history of childhood abuse was obtained using the Childhood Trauma Questionnaire. Diagnosis and clinical variables, including substance abuse, were based on structured clinical interviews (Structured Clinical Interview for DSM-IV Axis I disorders or French version of the Diagnostic Interview for Genetic Studies).
Cannabis abuse was significantly associated with childhood abuse, specifically emotional and sexual abuse (? 2 = 8.63, p = 0.003 and ? 2 = 7.55, p = 0.006, respectively). Cannabis abuse was significantly associated with earlier onset of the illness (z = -4.17, p
To see, if voluntary admission for treatment in first-episode psychosis results in better adherence to treatment and more favourable outcome than involuntary admission.
We compared consecutively first-admitted, hospitalised patients from a voluntary (n = 91) with an involuntary (n = 126) group as to psychopathology and functioning using Positive and Negative Syndrome Scale and Global Assessment of Functioning Scales at baseline, after 3 months and at 2 year follow-up. Moreover, duration of supportive psychotherapy, medication and number of hospitalisations during the 2 years were measured.
More women than men were admitted involuntarily. Voluntary patients had less psychopathology and better functioning than involuntary patients at baseline. No significant difference as to duration of psychotherapy and medication between groups was found. No significant difference was found as to psychopathology and functioning between voluntarily and involuntarily admitted patients at follow-up.
Legal admission status per se did not seem to influence treatment adherence and outcome.
First-episode psychosis (FEP) patients show structural brain abnormalities. Whether the changes are progressive or not remain under debate, and the results from longitudinal magnetic resonance imaging (MRI) studies are mixed. We investigated if FEP patients showed a different pattern of regional brain structural change over a 1-year period compared with healthy controls, and if putative changes correlated with clinical characteristics and outcome.
MRIs of 79 FEP patients [SCID-I-verified diagnoses: schizophrenia, psychotic bipolar disorder, or other psychoses, mean age 27.6 (s.d. = 7.7) years, 66% male] and 82 healthy controls [age 29.3 (s.d. = 7.2) years, 66% male] were acquired from the same 1.5 T scanner at baseline and 1-year follow-up as part of the Thematically Organized Psychosis (TOP) study, Oslo, Norway. Scans were automatically processed with the longitudinal stream in FreeSurfer that creates an unbiased within-subject template image. General linear models were used to analyse longitudinal change in a wide range of subcortical volumes and detailed thickness and surface area estimates across the entire cortex, and associations with clinical characteristics.
FEP patients and controls did not differ significantly in annual percentage change in cortical thickness or area in any cortical region, or in any of the subcortical structures after adjustment for multiple comparisons. Within the FEP group, duration of untreated psychosis, age at illness onset, antipsychotic medication use and remission at follow-up were not related to longitudinal brain change.
We found no significant longitudinal brain changes over a 1-year period in FEP patients. Our results do not support early progressive brain changes in psychotic disorders.
