Brain Changes in Fear

This protocol examines the neurobiology of fear and anxiety using various approaches. During fear conditioning in which a phasic explicit cue (e.g., a light) is repeatedly associated with an aversive unconditioned stimulus (e.g., a shock), the organism develops fear to the explicit cue as well as to the environmental context ...

Phase N/A

Expectation of Unpleasant Events in Anxiety Disorders

High-generalized anxiety is a concomitant of many anxiety disorders and is often regarded as a vulnerability marker for these disorders. One characteristic of patients with anxiety disorders and high trait-anxious individuals is inappropriate expectancies of aversive events. The overall aim of the present protocol is to investigate mechanisms that may ...

Phase N/A

The Psychobiology of Childhood Temperament

Objectives: The goal of this proposal is to study temperament and risk-taking as vulnerability factors for anxiety. Studies have documented that behaviorally inhibited (BI) children are at risk for anxiety disorders. This vulnerability may be associated with neural circuits underlying behavioral tendencies, such as components of the prefrontal cortex (PFC), ...

Phase N/A

Clinical Trial of Fluoxetine in Anxiety and Depression in Children and Associated Brain Changes

Objective: This protocol uses functional magnetic resonance imaging (fMRI) to examine neuro-cognitive correlates of pediatric and adult mood and anxiety disorders. The primary goal of the project is to document, in pediatric anxiety disorders and major depression, perturbations in brain systems mediating attention biases, fear conditioning, emotional memory, and response ...

Phase N/A

Effectiveness of Avapro in Obese Normotensive/Hypertensive African Americans

Using a crossover design, we will compare the effects of a placebo to an angiotensin II receptor antagonist on the urinary sodium excretion response in obese normotensive subjects and untreated hypertensive African-Americans subjects. We expect that the urinary sodium excretion response to angiotensin II receptor antagonist therapy will be less ...

Phase

Mindful Hearts Study

Evidence demonstrates that chronic stress doubles the risk of myocardial infarction and contributes to proinflammatory processes implicated in coronary artery disease and stroke. Veterans who have experienced combat are at greater risk for cardiovascular disease (CVD) compared to noncombat Veterans and non-Veterans. However, previous research has focused primarily on male ...

Phase N/A

Mechanism of Antidepressant-Related Dysfunctional Arousal in High-Risk Youth

The primary goals of this proposal are to investigate the etiological mechanisms associated with antidepressant-related dysfunctional emotional arousal and to characterize baseline neurobiological risk factors that predict the development of dysfunctional emotional arousal in treatment seeking youth with a family history of BD. Antidepressants have moderate benefit for treating mood ...

Phase N/A

A Comparison of Web-Prolonged Exposure (Web-PE) and Present-Centered Therapy (PCT) for PTSD Among Active-Duty Military Personnel

Background: It is urgent to make EBTs for military personnel readily accessible in order to meet the growing demand for effective and efficient treatment for PTSD in a timely manner. Effective EBTs for PTSD are available, but barriers to accessing care can deter military personnel from accessing care. Web-treatments represent ...

Phase N/A

Family Study of Affective and Anxiety Spectrum Disorders

Objective: The chief goal of this study is to identify the endophenotypes of the spectrum of mood disorders using the methods of genetic epidemiology, developmental psychopathology and clinical psychiatry/psychology. The major research questions focus on the specificity of familial transmission of the mood disorder spectrum (i.e., symptoms, symptom clusters, subtypes) ...

Phase N/A

Development of Magnetic Resonance Imaging Techniques for Studying Mood and Anxiety Disorders

A major component of understanding the pathogenesis of mood and anxiety disorders is expected to involve elucidation of abnormalities of brain structure and function associated with these conditions. Historically, post-mortem histopathological and neurochemical assessments constituted the primary methods for investigating abnormalities of brain structure and function in psychiatric disorders. However, ...
