Loss of self-understanding: a behavior-oriented model of depression.

Background: A new model of depression is proposed which is biological and explanatory on the behavioral level. It is hypothesized that a patient suffering from a depressive disorder loses the ability to produce one or more modes of behavior at a given time and simultaneously has the urge to produce one or more other modes of behavior constantly. The patient is also unable to interpret his behavioral disorder ("loss of self-understanding").
