Secondary tics are those in which an aetiology justifying them can be found, as compared to idiopathic tics, which make up the majority, and the Gilles de la Tourette syndrome (SGT), which is, at the moment, of unknown origin. Of the possible aetiologies described as causing tics, craneo-encephalic trauma has been mentioned on very few occasions. We present a case of post-traumatic tics (verbal and neck) in a young man of 24, and review the published cases which can be considered to be of post-traumatic tics. We have found six cases of tics secondary to traumas, all craneo-encephalic, like ours (the one under study). The time interval between the blow and the appearance of the tic or tics varied between 2 weeks and 3 months. The absence of significant lesions seen in the complementary investigations make it impossible for us to discover the site of the lesion caused by the trauma. However, the presence in some cases of other tics before the trauma, and of family histories of tics, supports the idea of a genetic basis or predisposition to suffer this disorder.
继发性抽动是指那些能够找到病因的抽动，与之相对的是特发性抽动（占大多数）和目前病因不明的 Gilles de la Tourette 综合征（SGT）。在已描述的可能导致抽动的病因中，颅脑外伤很少被提及。我们报告一例 24 岁青年男性的创伤后抽动（言语和颈部抽动）病例，并回顾已发表的可被认为是创伤后抽动的病例。我们发现了 6 例继发于创伤的抽动病例，均为颅脑创伤，与我们所研究的病例（本病例）一样。受伤与抽动出现之间的时间间隔在 2 周和 3 个月之间。补充检查中未发现明显病变，这使得我们无法确定创伤所致病变的部位。然而，有些病例在创伤前存在其他抽动以及有抽动家族史，这支持了该病存在遗传基础或易患倾向的观点。
