Purpose

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

Arms	Assigned Interventions
1 Subjects receiving Escitalopram (trade name: Lexapro) that are in the age range of 18-25	Drug: Escitalopram 10 mg of Escitalopram by mouth once a day for 8 weeks Other Name: Lexapro

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).

Eligibility

Ages Eligible for Study:	18 Years to 50 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Ages 18-50 years and able to give voluntary informed consent.
Satisfy criteria for Major Depressive Disorder (MDD) and current depressed episode using the Mini International Neuropsychiatric Interview (M.I.N.I.).
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:

Meeting DSM-IV criteria for schizophrenia, schizophreniform disorder, schizoaffective disorder, bipolar disorder, atypical psychosis, mental retardation, or organic mental (including organic mood) disorder.
On monoamine oxidase inhibitors in the past 2 weeks.
History of narrow angle glaucoma.
Lack of response of the current episode of depression to two or more adequate courses of antidepressant therapy at a clinically appropriate dose for a minimum of 4 weeks or, in the judgment of the investigator, the patient meets criteria for treatment-resistant depression.
