Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.In particular, this study will investigate whether variation in the serotonin transporter gene can affect the response to escitalopram as measured by clinical interview and MRI scan. We will measure activity in different parts of the brain, while subjects see pictures, using Magnetic Resonance Imaging (MRI) scan. There will be three MRI scans; one before we start any medication, one during the study after 3 weeks of treatment and one after six more weeks of treatment. Treatment will consist of Escitalopram. Additionally a blood sample will be taken for genetic testing. 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.
