Carbamazepine (CBZ) has a long history of successful use in epilepsy and, therefore, has a safety profile that is well characterised. Additionally, an extended-release formulation of CBZ (CBZ-ERC; Equetro, Shire US) has recently been approved for use in bipolar disorder. The most frequent adverse events associated with CBZ are somnolence, fatigue, dizziness and headache. Rash and leukopoenia may occur in approximately 10% of patients, but are benign and transient in most cases. Rare serious adverse effects include agranulocytosis, aplastic anaemia, Stevens-Johnson syndrome and toxic epidermal necrolysis. Although changes in lipid profiles have been noted, hyperglycaemia does not occur with CBZ, and clinically significant weight gain is uncommon. Proper monitoring and careful titration of the extended-release formulation should allow for successful use of CBZ in psychiatric patients.

Introduction: Bipolar disorder (BD) and major depressive disorder (MDD) have overlapping clinical presentations which may make it difficult for clinicians to distinguish them potentially resulting in misdiagnosis. This study combined structural MRI and machine learning techniques to determine whether regional morphological differences could distinguish patients with BD and MDD.
Methods: A total of 123 participants, including BD (n = 31), MDD (n = 48), and healthy controls (HC, n = 44), underwent high-resolution 3D T1-weighted imaging.

Bipolar disorder (BD) involves altered reward processing and decision-making, with inconsistencies across studies. Here, we integrated hierarchical Bayesian modelling with magnetoencephalography (MEG) to characterise maladaptive belief updating in this condition. First, we determined if previously reported increased learning rates in BD stem from a heightened expectation of environmental changes.

Bipolar disorder (BD) is a severe mental illness characterized by recurrent episodes of depression and mania. Lithium is the gold standard pharmacotherapy for BD, but outcomes are variable, and the relevant therapeutic mechanisms underlying successful treatment response remain uncertain. To identify synaptic markers of BD and lithium response, we measured the effects of lithium on induced pluripotent stem cell-derived neurons from BD patients and controls.

Introduction: Unipolar and bipolar mood disorders in older adults are accompanied by cognitive impairment, including executive dysfunction, with a severe impact on daily life. Up and till now, strategies to improve cognitive functioning in late-life mood disorders (LLMD) are sparse. Therefore, we aimed to assess the efficacy of adaptive, computerized cognitive training (CT) on executive and subjective cognitive functioning in LLMD.
