[Practice relevant research in biological psychiatry].

The practice of psychiatry would be unthinkable without modern psychopharmacology. Drug treatment, especially of severe psychiatric disorders, is often a precondition of community participation, societal reintegration and recovery. Seen in this context it is understandable that biological psychiatry has long been primarily defined by its close interconnection with psychopharmacology and has been perceived this way by practicing physicians. In recent years, however, the concept of what is "biological" has markedly expanded and so has the outreach of this approach into the practice of psychiatry. This article discusses examples showing that biological research methods provide new impulses for individualized medicine, psychotherapy and understanding environmental risks and therefore provide the basis for a preemptive and preventive approach that will be the key to master the challenges posed by the severe burden of mental illness.
