> Today scientific approaches based on modern biology, neuroscience and genomics are replacing nearly a century of purely psychological theories, yielding new approaches to the treatment of mental illnesses. Yes, I agree. My general sense is that when we start to figure out the basis for psychiatric diseases, those get moved into neurology's domain. I was looking at a psychiatry textbook and I was surprised to see Rett syndrome (a pervasive developmental disorder) listed as a psychiatric disease. It turns out that the textbook was quite old, and it wasn't up to date with the latest information about this disorder, whose cause is now known (MECP2 mutations, mostly).
