18 patients of the risk-group will receive placebo for 8 weeks in adjunction to their antidepressant standard therapy. Group allocation is randomised and double-blind. The placebo does not contain any psychoactive substance.
18 depressive patients without a heightened risk for BPD will not receive any medication apart from their standard antidepressant therapy (control-group).
