Progress on the mechanism of comorbidity of tic disorder and allergic diseases
Tic disorder(TD)is a complex chronic neuropsychiatric disorder characterized by rapid,involuntary,non-hythmic,single or multi-part muscle movement or vocal twitching.Both TD and allergic diseases are related to the body's immune imbalance.The symptoms involve different parts or organs,and the pathogenesis are complex,which seriously affect the quality of life.Clinical studies have found a clear correlation between TD and allergic diseases,but the relationship mechanism is still unclear,mainly involving neuro-immune cross-disorders.This paper reviews the research progress of the relevant mechanisms of TD and allergic diseases,in order to enhance the cognition of the two diseases,and provide new ideas and directions for the etiological research and treatment of TD.
