The pathogenesis of tic disorder in children is closely related to the dysfunction of the internal organs, especially the lung, spleen and liver. The main causes of tic disorder caused by visceral disorders are as follows: lung guard is the main cause of the disease, liver wind is the key to the pathogenesis and spleen deficiency and wind phlegm are the pathological basis. At the same time, the lung, liver, and spleen are mutually restrictive and affect each other. The main manifestations are that if the lung is affected by evil, the wood will punish the gold; if the spleen is insufficiency and the liver is hyperactive, the earth deficiency will be leading to over-restriction by wood. Based on the understanding of the related theories about viscera's disease and viscera's generation, we pay attention to distinguish the etiology and pathogenesis of the viscera, and we treat tic disorders based on syndrome differentiation of lung, liver and spleen with curative effect.
