背景资料：基于Tourette综合征（TS）与几种可能损害学校功能的临床特征相关的知识，以及越来越多的证据表明这种疾病比以前认为的更常见，作者假设TS和相关的抽动障碍与儿童人群的学校问题有关。方法：对纽约州罗切斯特市门罗县的1,596名学童进行了直接、盲法（教育安置）访谈。结果如下：在341名接受特殊教育的学生中，有27%的学生有抽搐，而在1,255名接受普通教育的学生中，有19.7%的学生有抽搐（p = 0.008）。抽搐的加权患病率估计值在SpEd中为23.4%，在RegEd中为18.5%。SpEd学生（7.0%）符合TS诊断标准的比例高于RegEd学生（3.8%; p = 0.01）。结论：虽然可能受到选择偏差的影响，但我们的研究结果表明，抽动障碍在儿童中很常见，并且与学校功能障碍高度相关。抽搐可能是导致学习困难的潜在大脑发育障碍的可识别标志。
Background: Based on the knowledge that Tourette's syndrome (TS) is associated with several clinical features that can impair school function and growing evidence that the disorder is much more common than previously thought, the authors hypothesized that TS and related tic disorders would be associated with school problems in the childhood population at large. Methods: Direct, blinded (to educational placement) interviews of 1,596 schoolchildren in Monroe County, Rochester, NY, were conducted. Results: Twenty-seven percent of 341 students classified as receiving special education (SpEd) had tics compared with 19.7% (p = 0.008) of 1,255 students in regular classroom programs (RegEd). The weighted prevalence estimates for tics were 23.4% in SpEd and 18.5% in RegEd. A higher percentage of students in SpEd (7.0%) met diagnostic criteria for TS than students in RegEd (3.8%; p = 0.01). Conclusions: Although possibly influenced by selection bias, our results indicate that tic disorders are common in children and are highly associated with school dysfunction. Tics may represent an identifiable sign of an underlying brain developmental disorder that contributes to academic difficulties.
