Learning Objectives:

  1. Knowing risk factors of recurrence in unipolar depression;
  2. Adapt treatment strategies to reduce each risk factor; and
  3. Conceptualize MDD cognitive impairment as consequences of recurrence.

Abstract:

After the first depressive episode, only one patient out of two will have at least another episode, but the risk of recurrence increases with each episode, getting closer to 100% after the 15th episode. This relatively negative outcome is also a signal that, potentially, preventing an episode could not only protect the patient from a difficult period of depressed months, but might also block this vivious circle, implying lifetime benefits. We will sum-up the most reliable factors on which the clinician may intervene, such as speed of diagnosis, optimize what is already
done, treat anxiety and other comorbidities, focus on compliance, associate other strategies than pharmacological treatment (psychotherapy, sport, tDCS...), focus on cognitions instead of emotions only, use symptom profile and make shared-decision with the patient.
