Evaluation of Patients With Mood and Anxiety Disorders and Healthy Volunteers

The purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol ...

Phase N/A

Effects of Arousal and Stress in Anxiety

Objective: Fear and anxiety are adaptive responses to different types of threats. Fear is a short-duration response evoked by explicit threat cues. Fear can best be studied using Pavlovian fear conditioning. Studies 1 and 2 examine learning processes underlying fear conditioning as well as the influence of cognitive and affective ...

Phase N/A

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

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

A clinical trial seeking patients for a research study for the treatment of Post-Traumatic Stress Disorder, Bipolar Disorder, Major depression, Panic Disorder

Objective A major component of understanding the pathogenesis of mood and anxiety disorders is expected to involve elucidation of abnormalities in 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. ...

Phase N/A

Using Neuroimaging to Investigate Major Depressive Disorder

The purpose of this study is to test whether the structural and functional connectivity between the dorso-lateral prefrontal cortex (DLPFC) and amygdala will decline as symptoms of co-morbid anxiety (Anxiety Factor Score) increase in patients with MDD. This decrease in connectivity will also account for decrease in treatment response. The ...

Phase N/A

Developing Field Tools for Real-Time Assessment of Exposure to Psychosocial Stress and Drug Use in an Outpatient Treatment Population

Background. This protocol arose in response to NIH s Genes and Environment Initiative (GEI). There is no genetic component to this protocol (update: no genetics initially but added by amendment in February 2013); rather, the goal is to develop field-deployable measures of environmental influences (stressors, drug exposure, etc.) that can ...
