Summary

The purpose of this study is to compare the effects on depressive symptoms of subjects who discontinue serotonergic antidepressants (a certain type of antidepressant, such as Prozac, that works on serotonin receptors in the brain) with the effects on depressive symptoms of subjects who continue to take serotonergic antidepressants. During this study, subjects will also be presented with the opportunity to undergo genetic testing for the serotonin gene transporter which has a short or long form. This is being done because it has been demonstrated that genetic testing improves outcome while treating treatment-resistant depression.
