Progress on the etiology of tic disorders in children / 国际儿科学杂志

Tic disorders(TD)are a group of childhood-onset neuropsychiatric conditions.Due to sudden, aimless, rapid muscle contraction, patients with TD often have different forms of tic such as blinking, frown, shoulder shaking and voice clearing, which seriously affect their quality of life.However, the etiology of TD has not yet been clear, hence the aim of patients management is targeted to symptom relief until now.In fact, many studies have found that the pathogenesis of TD could be a combined effect of multiple factors, including genetic, immunological, psychological and environmental variables.Here, we reviews the results of recent studies on the etiology of TD, hoping to provide new ideas and directions for the etiological research on TD.
