Motor and vocal tics are common in childhood. The received wisdom among clinicians is that for most children the tics are temporary, disappearing within a few months. However, that common clinical teaching is based largely on biased and incomplete data. The present study was designed to prospectively assess outcome of children with what the current nomenclature calls Provisional Tic Disorder. We identified 43 children with recent onset tics (mean 3.3 months since tic onset) and re-examined 39 of them on the 12-month anniversary of their first tic. Tic symptoms improved on a group level at the 12-month follow-up, and only two children had more than minimal impairment due to tics. Remarkably, however, tics were present in all children at follow-up, although in several cases tics were apparent only when the child was observed remotely by video. Our results suggest that remission of Provisional Tic Disorder is the exception rather than the rule. We also identified several clinical features present at the first examination that predict one-year outcome; these include baseline tic severity, subsyndromal autism spectrum symptoms, and the presence of an anxiety disorder.

临时性抽动症不是那么短暂。
运动和发声抽动在儿童时期很常见。临床医生普遍认为，对于大多数孩子来说，抽动症是暂时的，在几个月内消失。但是，这种常见的临床教学很大程度上是基于有偏见和不完整的数据。本研究旨在前瞻性评估具有当前术语称为临时性抽动症的儿童的结局。我们确定了43名近期发作抽动的儿童（自抽动发作以来平均3.3个月），并在他们第一次抽动的12周年纪念日对他们中的39例进行了重新检查。在12个月的随访中，抽动症状在小组水平上有所改善，并且只有两个儿童因抽动而遭受的损害超过最小程度。然而，值得注意的是，在随访中所有儿童均出现抽动，尽管在某些情况下抽动仅在通过视频远程观察到该儿童时才可见。我们的结果表明，暂时性抽动症的缓解是例外而不是规则。我们还在第一次检查中发现了几种临床特征，这些特征可以预测一年的预后。这些包括基线抽动严重程度，亚综合征自闭症谱系症状和焦虑症的存在。
