ABSTRACT
Tic disorder (TD) is a common neuro-developmental disorders in children during school age. The cause is complex and it can be induced or aggravated by varies of factors such as genetics, exogenous pathogens, and emotions. TD affects children's self-cognition, academic level, and social function, and causes parents to have unhealthy psychological states such as anxiety and depression, and affects family harmony. Therefore, clinical attention should not only be paid to the treatment of this disease, but also to prevention and nursing care. Incubative evil theory is one of the important theories of Traditional Chinese Medicine. This theory can help to treat and prevent diseases. Incubative evil is characterized by no symptoms with spontaneous attack by latent pathogen, but symptoms appearance induced by the pathogen. The pathological process of TD is similar to incubative evil characteristics. This paper discusses the prevention and nursing care of children's tic disorder based on the theory of incubative evil.
