Most psychiatric disorders are moderately to highly heritable. The degree to which genetic variation is unique to individual disorders or shared across disorders is unclear. To examine shared genetic etiology, we use genome-wide genotype data from the Psychiatric Genomics Consortium (PGC) for cases and controls in schizophrenia, bipolar disorder, major(More)
BACKGROUND The aims of this study were to describe outcome with respect to persistent psychotic symptoms, relapse of positive symptoms, hospital admissions, and application of treatment by coercion among patients with recent onset schizophrenia being adherent and non-adherent to anti-psychotic medication. MATERIALS AND METHODS The study included 50(More)
BACKGROUND Patients with schizophrenia have a high risk of cardiovascular disease (CVD). High aerobic intensity training (HIT) improve peak oxygen uptake (VO(2peak)), net mechanical efficiency of walking and risk factors for CVD but has not been investigated in patients with schizophrenia. AIMS To investigate effects from HIT on VO(2peak), net mechanical(More)
BACKGROUND In the present study we investigated genetic variants associated with bipolar disorder in a homogenous Norwegian sample, and potential genetic overlap with schizophrenia, using the Affymetrix 6.0 array. METHODS We carried out a genome-wide association study (GWAS) by genotyping 620 390 single-nucleotide polymorphisms (SNPs) in a case-control(More)
The phosphodiesterase 4B (PDE4B), which is involved in cognitive function in animal models, is a candidate susceptibility gene for schizophrenia (SZ) and bipolar disorder (BP). Variations in PDE4B have previously been associated with SZ, with a suggested gender-specific effect. We have genotyped and analyzed 40 and 72 tagging single nucleotide polymorphisms(More)
BACKGROUND The literature on the neuropsychological profiles in Bipolar disorder (BD) depression is sparse. The aims of the study were to assess the neurocognitive profiles in treatment-resistant, acutely admitted BD depression inpatients, to compare the neurocognitive functioning in patients with BD I and II, and to identify the demographic and clinical(More)
UNLABELLED BACKGROUND Patients with chest pain or palpitations often have poor outcomes following a negative cardiac evaluation, with symptom persistence, limitations in everyday activities, and reduced health-related quality of life. The aims of this study were to evaluate illness perceptions before and after negative cardiac evaluations and measure the(More)
BACKGROUND There is conflicting evidence regarding the educational level and its importance for social and occupational functioning in bipolar disorder (BD). The aim of this study was to investigate how educational achievement relates to function in BD compared with the general population, and which clinical factors are associated with level of education.(More)
BACKGROUND The aims of the present study were to investigate clinically relevant patient and environment-related predictive factors for threats and violent incidents the first three days in a PICU population based on evaluations done at admittance. METHODS In 2000 and 2001 all 118 consecutive patients were assessed at admittance to a Psychiatric Intensive(More)
Substance use is prevalent in patients with psychiatric disorders and may cause severe symptoms in addition to complicating the diagnosis of psychiatric disorders. The aims of the study were to find the prevalence in use of alcohol, drugs, benzodiazepines, hypnotics, opiates and stimulants, and to find the prevalence of substance use disorders at admission(More)
