Antidepressant-Resistant Depression and Antidepressant-Associated Suicidal Behaviour : The Role of Underlying Bipolarity

Abstract EN

The complex relationship between the use of antidepressants and suicidal behaviour is one of the hottest topics of our contemporary psychiatry.

Based on the literature, this paper summarizes the author's view on antidepressant-resistant depression and antidepressant-associated suicidal behaviour.

Antidepressant-resistance, antidepressant-induced worsening of depression, antidepressant-associated (hypo)manic switches, mixed depressive episode, and antidepressant-associated suicidality among depressed patients are relatively most frequent in bipolar/bipolar spectrum depression and in children and adolescents.

As early age at onset of major depressive episode and mixed depression are powerful clinical markers of bipolarity and the manic component of bipolar disorder (and possible its biological background) shows a declining tendency with age antidepressant-resistance/worsening, antidepressant-induced (hypo)manic switches and “suicide-inducing” potential of antidepressants seem to be related to the underlying bipolarity.
