Book excerpt: The Bipolar Book covers not only clinical and pathophysiological matters, but also technical aspects of the evidence accumulation for treatment of bipolar disorder. This approach brings in stimulating discussions on available data originating from current randomized controlled trials with specified considerations of bipolar mania, depression, and prophylaxis by providing accompanying recommendations for an improved evidence formation and synthesis. The Bipolar Book provides a clinician-friendly view of debatable issues on the existing randomized trials based evidence and the ways of improving them by respecting distinctive fluctuating pattern of bipolar disorder.
