Official title
Probing Amygdalo-Cortical Circuitry in Anxiety Disorders
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
A diverse body of research has implicated the amygdalo-cortical circuitry in the pathophysiology of anxiety disorders. For example, one model of PTSD posits exaggerated amygdala responsivity to threat-related stimuli as well as deficient top-down modulation of amygdala responses by specific cortical regions, including the pregenual anterior cingulate cortex, subcallosal cortex, and hippocampus. The investigators propose to investigate the pathophysiology of several specific anxiety disorders, Posttraumatic Stress Disorder (PTSD), Panic Disorder (PD), and Specific Phobia(SP), by using cognitive activation paradigms and magnetic resonance imaging (MRI) to probe the function and structure of implicated amygdalo-cortical circuitry.
