Neurofunctional Predictors of Escitalopram Treatment Response in Adolescents With Anxiety — FiESTAA  

Anxiety Clinical Trial

Official title:
Neurofunctional Predictors of Escitalopram Treatment Response in Adolescents With Anxiety

Clinical Trial Summary

Neurofunctional Predictors of Escitalopram Treatment Response in Adolescents with Anxiety. To determine the effects of escitalopram on functional activation patterns during a Continuous Performance Task with Emotional and Neutral Distracters, the CPT-END. To examine baseline functional activity and functional connectivity profiles in the ventrolateral prefrontal cortex as markers of subsequent treatment response to escitalopram in adolescents with generalized anxiety disorder (GAD). To use proton magnetic resonance spectroscopy (1H MRS) to examine glutamatergic and γ-aminobutyric acid (GABA)-related abnormalities in the anterior cingulate in adolescents with GAD as compared to healthy adolescents.

Clinical Trial Description

The long-term goal of this study is to explore the neurobiological basis of generalized anxiety disorder (GAD) using a validated functional MRI (fMRI) paradigm and functional connectivity analyses with a cohort of GAD patients and healthy subjects and generating feasibility and preliminary data regarding treatment-related effects of escitalopram on brain functional activation and Fc patterns in pediatric GAD. An additional goal is to identify biological markers in saliva and urine that will predict treatment response in pediatric subjects with GAD. The central hypothesis of this proposal is that core dysfunction within the prefrontal-amygdala network, which the investigators and others have observed in GAD, will be normalized by successful treatment. The rationale underlying this hypothesis is that, despite the high prevalence of GAD, there is a need to understand its neurobiology and to identify biomarkers of treatment response and the mechanisms by which selective serotonin reuptake inhibitors (SSRIs) putatively effect changes in the neurocircuitry of pediatric GAD. ;
