Abstract: Tic disorder（TD）is a neurodevelopmental disorder primarily characterized by motor and/or vocal tics. Obsessive-compulsive disorder（OCD）is a common comorbidity of TD. Early identification of obsessive thoughts and behaviors in children with TD，and early intervention for co-occurring conditions，can improve the prognosis of these children.In recent years，research on TD comorbid with OCD has increased both domestically and internationally. This review summarizes the epidemiology，etiological mechanisms，clinical manifestations，and treatment interventions for TD comorbid with OCD，aiming to enhance clinicians’understanding of this field and promote early identification and intervention for children with TD comorbid with OCD.

Key words: tic disorder, obsessive-compulsive disorder, early identification, early intervention

摘要： 抽动障碍（TD）是一种以运动抽动和（或）发声抽动为主要特征的神经发育障碍。强迫障碍（OCD）是TD常见的共患病之一。尽早识别TD患儿的强迫思维和行为症状，并对两者共患的情况进行早期干预，有助于改善患儿的预后。近年来，国内外对TD共患OCD的研究日益增多。文章对TD共患OCD的流行病学、病因学机制、临床表现及治疗干预措施进行阐述，以增进临床工作者对该领域的认识，推动TD共患OCD患儿的早期识别与干预。
