Brain, Biology and Mood Study
The purpose of the Brain, Biology and Mood study is to examine the association between stress, depression and cell death in the hippocampus. We fully expect this study to highlight components of a "stress vulnerability pathway" that will be amenable to new pharmaceutical development and to improved diagnostic methods for patients with major depression. The centerpiece of this program is a prospective study comparing unmedicated depressed patients with matched healthy controls at baseline and then following the depressed patients over the course of several months of standardized antidepressant treatment to gauge which baseline abnormalities normalize over the course of treatment.

Experimental: Treatment with SSRI
Depressed participants will be given the option of receiving 8 weeks of treatment with one of the following serotonin-specific reuptake inhibitors:
fluoxetine (Prozac®), sertraline (Zoloft®), paroxetine (Paxil®), citalopram (Celexa®), escitalopram (Lexapro®)
The treatment arm of the study is completely optional. The specific drug used for treatment will be selected by the study clinician based on clinical interviews and the participants preferences. Participants will be monitored for response and side effects by study clinician and will return after 8 weeks for a follow up study visit.
Drug: Treatment with SSRI
Participants who choose to enroll in this phase are treated with an FDA-approved SSRI in an open-label "treatment-as-usual" manner, in accordance with clinical practices and at a titration rate no more rapid than the manufacturer's recommendations. The duration of the treatment phase is 8 weeks.
Other Name: fluoxetine (Prozac®), Sertraline (Zoloft®), paroxetine (Paxil®), citalopram (Celexa®), escitalopram (Lexapro®)
Following an initial telephone screen to assess inclusion and exclusion criteria, the evaluation will continue with an in-person evaluation to assess the presence or absence of active medical history and history of major psychiatric illness, as well as review of the consent document. Eligible, consenting healthy control and depressed subjects will complete a urine screening test for drugs of abuse (and pregnancy for women of child-bearing capacity), psychological tests measuring mood and memory, have a blood draw of approximately 190 cc, and be given materials and instructions for home saliva and urine collection. This will be the end of the study procedure for the healthy controls. Depressed subjects, but not the healthy controls, will then have the option of receiving an 8-week open label treatment with an FDA-approved antidepressant (to be decided upon between the subject and study psychiatrist). Additional repeat behavioral evaluations and a repeat full biochemical evaluation (identical to baseline) will be performed at Week 8.
We have elected to use an open-label design for the antidepressant treatment phase of our study, instead of a double-blind-placebo controlled one, since: (a) there are some ethical concerns involved in treating actively depressed patients with placebo medication for extended periods of time, (b) recruitment of subjects into this study will be greatly enhanced if all subjects know they will receive an active antidepressant drug, and (c) our goal is to assess whether measurement of these factors provides clinically useful information in clinical settings as predictors of later clinical response (rather than having as a goal the demonstration of the clinical efficacy of FDA-approved antidepressants).
The following is a description of the antidepressant treatment phase for the depressed subjects: Depressed subjects will begin an 8-week open-label outpatient study assessing the neuroendocrine, antidepressant and anti-anxiety effects of antidepressant treatment. Participants will be treated with an FDA-approved SSRI antidepressant under the supervision of a study psychiatrist. Treatment will be continued for 8 weeks, unless the subject wishes to stop treatment earlier, the clinician determines it to be in the subject's best interest to stop treatment earlier, or the subject meets certain discontinuation criteria detailed below. Behavioral, biological and physiological assessments (described below) will be performed at baseline and at the end of week 8. In between these primary assessment points, depressed subjects will have scheduled clinical evaluations (without any specific study-related biological and physiological testing and with limited formal behavioral ratings, described below) after 1, 2 and 3 weeks of starting treatment and thereafter according to clinicians' judgment and clinical need, to monitor clinical response and safety.
After the end of the study, a physician-investigator will meet with the depressed subjects to review their clinical responses to treatment and to make further treatment suggestions, which the subjects may use in discussions of their future treatment options with their personal physicians. If a decision is made to discontinue antidepressant treatment, the subjects will be given instructions on how to withdraw from the medication, and will be given up to a 4 week supply of the drug to facilitate this withdrawal.
