[Advanced imaging methods as a basis for more reliable classification and better treatment for patients with depressive symptoms--an example for conceptual change in the psychiatric diagnostic method].

The current editorial study focuses on the idea of using advanced imaging methods in order to better classify and treat patients with depression and other psychiatric illnesses. The editorial is based on the review of Heymann and Bonne, published in this issue of the journal, showing differences between bi-polar and uni-polar depression using functional neuroimaging methods. This example, although not applicable yet in clinical practice, is the basis for future advances in psychiatric classification, together with clinical subtyping, and more biological markers, including genetic profiling.
