PURPOSE To compare the hippocampal volumes in patients with bipolar disorder (BD) and healthy controls, obtained by applying different segmentation methods (manual, Freesurfer [FS], and FSL). MATERIALS AND METHODS The study included 27 patients with BD and 40 healthy controls. T1-weighted images in the sagittal plane were acquired on a 3 Tesla (T) MR(More)
Early life stress (ELS; sexual abuse, physical abuse, emotional abuse, physical neglect, and emotional neglect) has been the focus of numerous studies. It has been associated with the onset and the severity of psychiatric disorders in adults. The objective of this study was to review the literature on ELS associated with psychiatric disorders in adulthood,(More)
Previously, we have shown that in vitro antidepressants modulate glucocorticoid receptor (GR) function and expression, and have suggested that these effects could be relevant for the mechanism of action of antidepressants. To further clarify the interaction between antidepressants and glucocorticoids, we evaluated the in vitro effect of the tricyclic(More)
Bipolar affective disorders often require adjunctive therapy to treat persistent symptoms. In order to evaluate bipolar symptoms inadequately responsive to lithium, we have compared the effects of two structurally related compounds carbamazepine (CBZ) and oxcarbazepine (OXC). We evaluated the efficacy and safety of CBZ and OXC administration in residual(More)
OBJECTIVE Hypercortisolaemia has been well described in depression and may be a factor associated with treatment resistance. The role of the more abundant adrenal steroid dehydroepiandrosterone (DHEA) has been recently investigated, with some evidence that it may have an antiglucocorticoid effect. This study measured cortisol, DHEA and their ratio in(More)
BACKGROUND People with severe depressive illness have raised levels of cortisol and reduced glucocorticoid receptor function. AIMS To obtain a physiological assessment of hypothalamic-pituitary-adrenal (HPA) axis feedback status in an in-patient sample with depression and to relate this to prospectively determined severe treatment resistance. METHOD The(More)
OBJECTIVE To review the new findings about stress, hypothalamic-pituitary-adrenal axis and depression trying to explain a possible endophenotype prone to depression. METHOD Nonsystematic review of the literature based on the endophenotype hypothesis. RESULTS Depression is linked to hypercortisolemia in many patients, but not all patients present these(More)
OBJECTIVE We reviewed previous studies that have described an association between abnormal functioning of the hypothalamic-pituitary-adrenal axis and depression. In addition to melancholic depression, a spectrum of conditions may be associated with increased and prolonged activation of the hypothalamic-pituitary-adrenal axis. In contrast another group of(More)
We evaluate the association between subtypes of early life stress (ELS; sexual abuse, physical abuse, emotional abuse, physical neglect, and emotional neglect) and psychiatric disorders in adults. The sample was composed of 81 adult psychiatric patients treated at the Day Hospital Unit in Brazil. The patients were assessed using the Mini International(More)
The amygdala has a key role in automatic non-conscious processing of emotions. Highly salient emotional stimuli elicit amygdala activity, and happy faces are among the most rapidly perceived facial expressions. In backward masking paradigms, an image is presented briefly and then masked by another stimulus. However, reports of amygdala responses to masked(More)
