Research into the impact of genetic mutations on brain development has revealed that conditions previously considered distinct often have common genetic underpinnings, so there is bound to be overlap between psychiatric disorders as they have been defined traditionally.

One of the goals is to help medics identify mild forms of severe illnesses such as schizophrenia before people have experienced their first serious psychotic episode, in the hope of stopping the disease progressing.
But DSM-V will also propose new conditions, such as “complicated grief”, which describes bereaved people who may benefit from being treated as if for major depression.
Antithesis is the use of contrasting concepts, words, or sentences within parallel grammatical structures.
This combination of a balanced structure with opposite ideas serves to highlight the contrast between them.
The aim is to help doctors offer patients the most appropriate treatment.
But an important by-product will be that researchers working on the psychiatric drugs of the future will be able to test them in genetically engineered animal models that more closely resemble human reality.
The reward circuits, for instance, are implicated in addiction, schizophrenia, depression and obsessive-compulsive disorder.
According to John Krystal, the editor of , one of the field's leading journals, what seems to be emerging is a completely new way of looking at psychiatric diagnosis in which there is no one-to-one relationship between genes and symptoms but, rather, genes affect the development of brain circuits and this then produces symptoms.
A malfunctioning version of the protein encoded by this gene contributes, as its name suggests, to schizophrenia. Likewise, genes involved in making the myelin sheaths that insulate nerve cells go wrong in both schizophrenic and bipolar patients.
In this context it is no surprise that a decade of brain imaging has shown the same neuronal circuits to be involved in many disorders.
