抽动秽语综合征患儿脑干听觉诱发电位的研究

Brainstem auditory evoked potential of patients with tourette syndrome

对 40例抽动 -秽语综合征患儿 (TS组 )和 32例健康儿童 (对照组 )行脑干听觉诱发电位 (BAEP)检查。结果 TS组 ～ 、 ～ 波峰间期较对照组显著延长 (P<0 .0 5 ) ,TS组 BAEP异常为轻度 17.5 %、中度 5 %、重度 2 .5 % ,异常率为 2 5 %。认为 TS患儿中枢脑干受到损害 ,损害程度为轻中度 ,但体格发育没有受到影响。

To observe the changes of brainstem auditory evoked potential(BAEP).40 patients with Tourette′s syndrome(TS) and 32 normal children were studied in BAEP.The results showed that Ⅰ～Ⅲ,Ⅰ～Ⅴ waves interpeak latencies were significantly pronlonged(P<0.05),and 10 cases(25%) showed abnormal BAEP.Those suggest that there are mild to moderate damages to brainstem,but the physique development is not affected.
