title: [The concept of anniversary reaction - an explanation for the onset of depression].
abstract: In this contribution, the concept of anniversary reaction is explained and elucidated by a paradigmatic case-report. The influence of a certain date, e.g. birthday, on mortality is epidemiologically well proven. The psychoanalytical comprehension of anniversary reaction emphasizes the significant coherence to a biographical trauma. An anniversary reaction emerges on a specific date or age of life that reminds and actualises the conflict attached to the trauma. The anniversary reaction may appear in the shape of a psychic or an organic disease. In the case described, the anniversary reaction emerged on the anniversary of the death of the partner of life that had initially been followed by pathological mourning.
