OBJECTIVE
Many neuropsychiatric disorders involve abnormal attentional processing. Systematic investigations of how attention may affect tic frequency in Tourette syndrome are lacking.
METHOD
Patients performed rhythmic finger movements, approximately once every 2 s. Each movement triggered a unique visual color stimulus. Patients were asked to monitor and remember their finger actions, the external colors caused by their actions, or their tics. Sixteen adult Tourette syndrome patients performed each task twice: once while inhibiting tics, and once without inhibiting tics.
RESULTS
During the "freely tic" condition, patients had significantly fewer tics when attending to finger movements, or to the ensuing colors, compared with when attending to their tics. Attention to fingers produced the fewest tics overall. During tic suppression, tic frequency was reduced to an equal level in all conditions.
CONCLUSIONS
Focusing attention away from tics significantly reduces tic frequency. This attentional process may operate by regulating motor noise.
目的
许多神经精神疾病都涉及异常的注意力处理。目前缺乏关于注意力如何影响抽动秽语综合征抽动频率的系统性研究。
方法
患者进行有节奏的手指运动，大约每2秒一次。每次运动触发一个独特的视觉颜色刺激。要求患者监测并记住他们的手指动作、动作引发的外部颜色或他们的抽动。16名成年抽动秽语综合征患者每项任务执行两次：一次抑制抽动，一次不抑制抽动。
结果
在“自由抽动”状态下，与关注自身抽动相比，患者在关注手指运动或随之出现的颜色时抽动明显减少。总体而言，关注手指时抽动最少。在抽动抑制期间，所有状态下抽动频率均降低到相同水平。
结论
将注意力从抽动上转移可显著降低抽动频率。这一注意力过程可能通过调节运动噪声起作用。
