If you or a loved one has suffered from depression, you may already be aware that not all treatments work the same for everyone. Some people are helped quickly, while for others it may take weeks before they feel a difference. We would like to learn why this is by identifying features in each person that are associated with better results. Knowing this will help doctors and patients to select the treatments that will work, rather than by trial-and-error.

Nobody should let their depression go untreated. There are a number of other resources available that explain the condition, describe the different kinds of treatment and therapy, and provide references to qualified physicians, therapists, and support groups.
