In the field of bipolar disorder, some proposals of a staging model have been suggested considering the progressive features of the disorder. The staging model regards special features of the patients and further draws a route to define the prognosis and treatment as well as the neurobiological background of the disorder. The aim of this model is to identify rational therapeutic targets and provide the most effective and less toxic intervention in a time-sensitive manner. Advocating for a model of staging in bipolar disorder that can group the patients according to quantitative cut-offs of common practice clinical variables as well as defining a biochemical correlation seems to be a further step towards an operative and valid model of staging in bipolar disorder.
