OBJECTIVES Neurocognitive dysfunction is milder in bipolar disorders than in schizophrenia spectrum disorders, supporting a dimensional approach to severe mental disorders. The aim of this study was to investigate the role of lifetime history of psychosis for neurocognitive functioning across these disorders. We asked whether neurocognitive dysfunction in(More)
OBJECTIVES Studies on neurocognitive functioning in bipolar disorder, reporting deficits in memory, attention, and executive functioning, have primarily focused on bipolar I disorder. The aim of this study was to examine whether patients with bipolar I and bipolar II disorder have different neurocognitive profiles. METHODS Forty-two patients with bipolar(More)
OBJECTIVE An association between bipolar disorder and cognitive impairment has repeatedly been described, even for euthymic patients. Findings are inconsistent both across primary studies and previous meta-analyses. This study reanalysed 31 primary data sets as a single large sample (N = 2876) to provide a more definitive view. METHOD Individual patient(More)
OBJECTIVES Cognitive dysfunction in bipolar disorder (BD) is well established in the literature; however, there are few studies of neurocognition in patients early in the course of the illness. In this study we compare neurocognitive function in a cohort of first-contact mania patients with a healthy control group matched for age, gender, and education. (More)
OBJECTIVE Impaired emotion perception is documented for schizophrenia, but findings have been mixed for bipolar disorder. In healthy samples females perform better than males. This study compared emotion perception in schizophrenia and bipolar disorder and investigated the effects of gender. METHOD Visual (facial pictures) and auditory (sentences)(More)
BACKGROUND The underlying nature of negative symptoms in psychosis is poorly understood. Investigation of the relationship between the different negative subsymptoms and neurocognition is one approach to understand more of the underlying nature. Apathy, one of the subsymptoms, is also a common symptom in other brain disorders. Its association with(More)
OBJECTIVE In schizophrenia, increased rates of somatic mortality have been shown to correspond with a high prevalence of cardiovascular risk factors, including smoking and the metabolic syndrome. In bipolar disorder, the amount of cardiovascular risk is still largely unknown. This study compares the prevalence of smoking and metabolic disturbances in(More)
Social cognition and learning potential have been proposed as mediating variables between neurocognition and functional outcome in schizophrenia. The present study examined this relation in a schizophrenia group (N = 26) with normal IQ. Neurocognition was measured with a composite score from tests of verbal learning, psychomotor speed, and executive(More)
In line with a dimensional approach to psychopathology, we examined whether psychosocial function and its relationship to neurocognition and clinical symptoms differ across schizophrenia and bipolar disorder subgroups with and without a history of affective or psychotic episodes. From the TOP study, a heterogeneous sample of individuals with schizophrenia(More)
OBJECTIVE To investigate potential risk factors for medication non-adherence in patients with schizophrenia and bipolar disorder. METHOD A total of 255 patients underwent clinical assessments, neurocognitive testing and blood sampling. The patients were divided into groups of 'No', 'Partial' or 'Full' adherence. Relationships to different risk factors(More)
