Study of Brain Response to Emotional Pictures Using a Magnetic Resonance Imaging (fMRI) While on Escitalopram
August 23, 2016 updated by: Indiana University School of Medicine
fMRI and Genotype Markers of Antidepressant Side Effects and Response in Young Adults Compare to Older Adults
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
Study Overview
Detailed Description
This study will measure the activity in different parts of the brain, while the patients are seeing some pictures, using Magnetic Resonance Imaging (MRI) scan.
For this study three MRI scans will be conducted.
One before the patient begins on any medication, one during the study after 3 weeks of treatment and one after six more weeks of treatment with a standard antidepressant called Escitalopram(trade name: Lexapro).

- 17-item Hamilton Depression Rating Scale (HDRS) score > 18.
- Satisfy criteria to undergo an MRI scan based on MRI screening questionnaire.
- Able to be managed as outpatients for initial assessment and during treatment as ascertained by the following -
- Symptoms not worsening by more than 10 points on the HDRS during the course of the study.
- No danger to self or others.
Exclusion Criteria:
