Neuroimaging studies using angry or contemptuous human facial photographic stimuli have suggested amygdala hyper-responsivity in social anxiety disorder (SAD). We sought to determine if an angry "schematic face" (simple line drawing) would evoke exaggerated amygdalar responses in SAD patients compared with healthy control (HC) subjects. Angry, happy, and(More)
CONTEXT Social anxiety disorder (SAD) is common and debilitating. Although exposure therapy is one of the most effective forms of psychotherapy for this disorder, many patients remain symptomatic. Fear reduction in exposure therapy is similar to extinction learning, and early clinical data with specific phobias suggest that the treatment effects of exposure(More)
BACKGROUND Little is known about the biological mechanisms underlying the excess medical morbidity and mortality associated with mood disorders. Substantial evidence supports abnormalities in stress-related biological systems in depression. Accelerated telomere shortening may reflect stress-related oxidative damage to cells and accelerated aging, and severe(More)
OBJECTIVE The authors provide a detailed perspective on the correlates of comorbid anxiety in a large, well-characterized sample of bipolar disorder patients. METHOD Anxiety and its correlates were examined in a cross-sectional sample from the first 500 patients with bipolar I or bipolar II disorder enrolled in the Systematic Treatment Enhancement Program(More)
Anxiety sensitivity is the fear of anxiety-related sensations, and is measured by the 16-item Anxiety Sensitivity Index (ASI). Despite the popularity and utility of the ASI in research, a number of studies have provided evidence for the inadequacy of several items, and item-to-scale correlations for the ASI have not been published. In this study, a(More)
Recent technological advances offer an opportunity to further elucidate the complex cytokine network in Major Depressive Disorder (MDD). Twenty cytokines were simultaneously assessed in 49 individuals with MDD and 49 age and gender matched controls. Multiple pro-inflammatory and two anti-inflammatory cytokines were significantly elevated in the MDD sample,(More)
BACKGROUND Pregabalin inhibits release of excess excitatory neurotransmitters, presumably by binding to the alpha2-delta subunit protein of widely distributed voltage-dependent calcium channels in the brain and spinal cord. OBJECTIVE To assess the anxiolytic efficacy of pregabalin in patients with generalized anxiety disorder. DESIGN Double-blind,(More)
OBJECTIVE The purpose of this study was to determine the efficacy of fluvoxamine for the treatment of social phobia (social anxiety disorder). METHOD In a 12-week multicenter, double-blind, randomized, placebo-controlled trial, 92 patients with social phobia were treated with the selective serotonin reuptake inhibitor fluvoxamine; 91.3% of the patients(More)
BACKGROUND Traditional combination strategies of cognitive-behavior therapy plus pharmacotherapy have met with disappointing results for anxiety disorders. Enhancement of cognitive-behavior therapy with d-cycloserine (DCS) pharmacotherapy represents a novel strategy for improving therapeutic learning from cognitive-behavior therapy that remains untested in(More)
Studies using fear-conditioning paradigms have found that anxiety patients are more conditionable than individuals without these disorders, but these effects have been demonstrated inconsistently. It is unclear whether these findings have etiological significance or whether enhanced conditionability is linked only to certain anxiety characteristics. To(More)
