Bipolar disorder is a common disease in psychiatric clinics. TCM treatment has its own advantages and characteristics. Syndrome differentiation and treatment is the core of TCM

while syndromes are the core of syndrome differentiation and treatment. At present

there has been still a lack of unified standards of the syndromes. Therefore

on the basis of ancient and modern literature research

clinical epidemiological investigation and Delphi method research

the Professional Committee of Psychosis Branch of Chinese Association of Integrative Medicine were summoned to discuss the TCM syndrome classification and the syndrome-symptoms of the bipolar disorder for three times. Finally

the expert consensus standard of TCM syndrome differentiation and classification of the bipolar disorder has been determined. TCM syndromes of the bipolar disorder were divided into 3 types in mania and 5 types of depressive episodes according to this standard. Every syndrome has to meet 4 symptoms of the main symptoms plus 5 symptoms of sub-symptoms before diagnosis can be made. At the same time

the relevant symptoms which are of four diagnosis information can be quantified by experts

so that the research work can be unified and quantified

especially in scoring the curative effect of TCM syndrome in clinical research.
