Study of Brain Response to Emotional Pictures Using a Magnetic Resonance Imaging (fMRI) While on Escitalopram

Completed · Phase 4

Conditions studied: Major Depression

In brief

The purpose of this study is to find out what parts of the brain have increased or decreased activity when people are depressed and how antidepressant medicine changes this activity in depressed patients. The genetic samples collected are to look at variation in a gene (serotonin transporter gene), which affects the functioning of the chemical serotonin in the brain
