Each person will have different symptoms of depression and the episodeâs length will vary. The sooner someone seeks treatment, the sooner their depression can be cured and its symptoms alleviated. In mild or moderate depression, individuals can get relief within several weeks or months. Major depression can take longer. Patients with this form of the disorder will often require treatment for several months and in rare cases, it may take more than a year to be completely free of the condition.
