Here's a question: "Are all mental disorders diseases?" Each school of psychiatry looks totally differently at how to answer this question. Traditional psychiatry(Heidelberg school)sticks stance that some mental disorders are diseases and some are not. On the other hand, brain scientists may insist that all mental disorders are brain diseases. DSM leaves this question open and sidesteps the controversial issue of the definition of "disease" in psychiatry. Differences in diagnostic methods and classification between the two systems and the advantages and disadvantages of each are discussed. Traditional psychiatry and DSM are not essentially conflicting but complement each other. We should use each system according to the intended use. When with a patient in a daily clinical setting, the thoughts of the Heidelberg school are more useful than DSM, but DSM has a marked effect on research and studies where many patients need to be included.
