Emotions of fear and disgust are related to core symptoms of depression. The neurobiological mechanisms of these associations are poorly understood. This functional magnetic resonance imaging study aimed at examining the Blood oxygenation level dependent (BOLD) response to facial expressions of fear and disgust in patients with major depressive disorder.(More)
OBJECTIVE The main aim of this study was to investigate the effects of Huntington's disease (HD) on cognitive and affective Theory of Mind (ToM) abilities. The relation of ToM performance and executive functions was also examined. METHOD Eighteen HD patients, early in the course of the disease, and 18 healthy volunteers matched for age and educational(More)
BACKGROUND Over the past decade, evidence has accumulated to suggest that people suffering from Major Depressive Disorder (MDD) present impairment in attention, working memory, executive function, including cognitive inhibition, problem- and task-planning. The aim of the current study was to assess inhibitory mechanisms within working memory with(More)
Suboptimal performance in working memory (WM) tasks and inefficient prefrontal cortex functioning are related to dysregulation of dopaminergic (DA) and hypothalamic-pituitary-adrenal systems. The aim of the present study was to investigate the joint effect of genetic polymorphisms coding for DA catabolism and glucocorticoid receptor (GR, NR3C1) on brain(More)
Imaging genetic studies showed exaggerated blood oxygenation level-dependent response in limbic structures in carriers of low activity alleles of serotonin transporter-linked promoter region (5-HTTLPR) as well as catechol O-methyltransferase (COMT) genes. This was suggested to underlie the vulnerability to mood disorders. To better understand the mechanisms(More)
This article presents a prospective study of 71 patients infected with chronic viral hepatitis C and treated with interferon alpha during one year. The objective was to assess the incidence and predictive factors of anxiety and depression symptoms during and after the therapy. Each patient received psychiatric assessment before, during and after treatment,(More)
Huntington disease (HD) is a neurodegenerative disorder due to an excessive number of CAG repeats in the IT15 gene on chromosome 4. Studies of cognitive function in asymptomatic gene carriers have yielded contradictory results. This study compared cognitive performance in 44 subjects with the HD mutation (group of carriers) who had no clinical signs of HD(More)
Psychiatric disorders, especially depression, are frequent in patients with multiple sclerosis (MS). They are attributed both to the psychosocial impact of a chronic, usually progressive, disabling illness and to cerebral demyelination. Besides, drugs such as corticosteroids and possibly interferon (IFN) may also have depressogenic effects. Major depressive(More)
Adverse effects of interferon (IFN) treatment are common, and efforts to minimize these reactions are of considerable importance. IFN-beta-1a is an established therapy for patients with relapsing-remitting multiple sclerosis (MS). Its psychiatric side effects are debated and not yet fully established. The authors report here the case of a patient on(More)
BACKGROUND There is evidence showing that men and women differ with regard to the processing of emotional information. However, the mechanisms behind these differences are not fully understood. METHOD The sample comprised of 275 (167 female) right-handed, healthy participants, recruited from the community. We employed a customized affective priming task,(More)
