The Importance of Psychotherapy for Treatment-Resistant Depression.

Many clinicians choose psychoanalytic psychotherapy or supportive psychotherapy as the primary method of treating depression with or without antidepressant medications. Despite new antidepressants, 20% or more patients showed inadequate responses to the medications, and remained in chronic courses, known as "treatment-resistant depression (TRD)."In this chapter, we described (1) the reasons for psychotherapy in treating TRD from the perspectives of the hazard of polypharmacy, resistance, and neural mechanisms. (2) Next, we focused on the importance of assessment with two clinical vignettes and the original modality of psychoanalysis, psychoanalytic psychotherapy, and supportive psychotherapy in brief. (3) Finally, we described specific considerations in undertaking psychotherapy for TRD patients in terms of transference, countertransference, and resistance. In addition, the efficacy of psychoanalytic psychotherapy in childhood, adolescent, and late-life depression has been depicted in this paper.
