本研究的目的是通过对10名受月经期无先兆偏头痛影响的受试者在发作期和发作间期进行皮层电磁刺激来评估兴奋性阈值和中枢运动传导时间（CCT）。患者选自254名受偏头痛影响的门诊患者，根据国际头痛协会标准进行诊断。1对照组由10名健康女性受试者组成。就CCT而言，患者和对照组之间没有差异。然而，在患者组中，我们发现在发作期和发作间期以及两个半球的兴奋性阈值显著增加。如果得到证实，兴奋性阈值的增加可能是无先兆偏头痛的一个有用的神经生理学相关。
The purpose of the present study was the evaluation of the excitability threshold and the central motor conduction time (CCT) studied by means of electromagnetic cortical stimulation in ten subjects affected by menstrual migraine without aura, both in the ictal and the interictal period.The patients were chosen from among a group of 254 outpatients affected by migraine, diagnosed according to the international Headache Society criteria.1 The control group consisted of ten healthy female subjects. As far as CCTs were concerned no differences emerged between patients and controls. However in the patient group we found a significant increase in the excitability threshold values, both in the ictal and the interictal period, and in both hemispheres. If confirmed, the increased excitability threshold may be a useful neurophysiological correlate of migraine without aura.
