OBJECTIVE Lithium remains a first-line treatment for bipolar disorder, but the mechanisms by which it prevents the recurrence of mood episodes are not known. The authors utilized data from a genomewide association study to examine associations between single nucleotide polymorphisms (SNPs) and the outcome of lithium treatment in two cohorts of patients with bipolar I disorder or bipolar II diso...

A 55-year-old man with congenital hemiparesis of the right side, three episodes of generalised tonic-clonic seizure at 16 years of age, and two episodes of severe depression and two episodes of hypomania in the past, presented with severe depression with psychotic symptoms. Computed tomography of the brain showed a grey matter-lined cerebrospinal fluid-filled cleft in the left cerebral hemisphe...

CONTEXT Affective disorders are common in women, with many episodes having an onset in pregnancy or during the postpartum period. OBJECTIVE To investigate the occurrence and timing of perinatal mood episodes in women with bipolar I disorder, bipolar II disorder, and recurrent major depression (RMD). SETTING AND PATIENTS Women were recruited in our ongoing research on the genetic and nongenetic ...

BACKGROUND Nearly all information processing during cognitive processing takes place during periods of sustained attention. Sustained attention deficit is among the most commonly reported impairments in bipolar disorder (BP). The majority of previous studies have only focused on bipolar I disorder (BP I), owing to underdiagnosis or misdiagnosis of bipolar II disorder (BP II). With the refinemen...

OBJECTIVE There has been little investigation of early trauma in bipolar disorder despite evidence that stress impacts on the course of this illness. We aimed to compare the rates of childhood trauma in adults with bipolar disorder to a healthy control group, and to investigate the impact of childhood trauma on the clinical course of bipolar disorder. METHODS Retrospective assessment of child...

Key words: bipolar disorder-unipolar depression – diagnosis – treatment – guidelines-suicidality Increasing understanding of the bipolar spectrum of disorders has led to an increasing integration of concepts regarding the aetiology and treatment of affective disorders. Thus, for example, we now understand that an illness, previously believed to be recurrent depressive disorder, may develop over...

In executive function, specifically in response inhibition, numerous studies support the essential role for the inferior frontal cortex (IFC). Hypoactivation of the IFC during response-inhibition tasks has been found consistently in subjects with bipolar disorder during manic and euthymic states. The aim of this study was to examine whether reduced IFC activation also exists in unmedicated subj...

OBJECTIVE The authors' goal was to determine whether patients with bipolar II disorder had altered regional brain responses to novel motor sequences. METHOD Regional cerebral blood flow was measured with positron emission tomography in 13 patients with bipolar II disorder and 14 healthy comparison subjects. Participants performed a serial reaction time task in which they were visually cued to...

OBJECTIVE Migraine is a common comorbidity of bipolar disorder and is more prevalent in women than men. We hypothesized comorbid migraine would be associated with features of illness and psychosocial risk factors that would differ by gender and impact outcome. METHOD A retrospective analysis was conducted to assess association between self-reported, physician-diagnosed migraine, clinical vari...
