OBJECTIVES Little evidence is available on the role of transcranial direct current stimulation (tDCS) in patients affected by chronic migraine (CM) and medication overuse headache (MOH). We aim to investigate the effects of tDCS in patients with CM and MOH as well as its role on brain activity. METHODS Twenty patients with CM and MOH were hospitalized for a 7-day detoxification treatment. Upon admission, patients were randomly assigned to anodal tDCS or sham stimulation delivered over the primary motor cortex contralateral to the prevalent migraine pain side every day for 5 days. Clinical data were recorded at baseline (T0), after 1 month (T2) and 6 months (T3). EEG recording was performed at T0, at the end of the tDCS/Sham treatment, and at T2. RESULTS At T2 and T3, we found a significant reduction in monthly migraine days (p = 0.001), which were more pronounced in the tDCS group when compared to the sham group (p = 0.016). At T2, we found a significant increase of alpha rhythm in occipital leads, which was significantly higher in tDCS group when compared to sham group. CONCLUSIONS tDCS showed adjuvant effects to detoxification in the management of patients with CM and MOH. The EEG recording showed a significant potentiation of alpha rhythm, which may represent a correlate of the underlying changes in cortico-thalamic connections. SIGNIFICANCE This study suggests a possible role for tDCS in the treatment of CM and MOH. The observed clinical improvement is coupled with a potentiation of EEG alpha rhythm.

阳极经颅直流电刺激治疗慢性偏头痛和药物过度使用性头痛:一项双盲随机假对照试验

目标 关于经颅直流电刺激 (tDCS) 在受慢性偏头痛 (CM) 和药物过度使用性头痛 (MOH) 影响的患者中的作用的证据很少。我们旨在研究 tDCS 对 CM 和 MOH 患者的影响及其对大脑活动的作用。方法 20 名 CM 和 MOH 患者住院接受 7 天的排毒治疗。入院后,患者被随机分配接受阳极 tDCS 或假刺激,每天在偏头痛偏头痛侧的对侧初级运动皮层上进行,持续 5 天。在基线 (T0)、1 个月 (T2) 和 6 个月 (T3) 后记录临床数据。EEG 记录在 T0、tDCS/Sham 治疗结束时和 T2 时进行。结果在 T2 和 T3,我们发现每月偏头痛天数显着减少(p = 0.001),与假手术组相比,tDCS 组更明显(p = 0.016)。在 T2 时,我们发现枕骨导联的 alpha 节律显着增加,与假手术组相比,tDCS 组显着更高。结论 tDCS 在 CM 和 MOH 患者的管理中显示出辅助解毒作用。脑电图记录显示 α 节律显着增强,这可能与皮质-丘脑连接的潜在变化有关。意义 这项研究表明 tDCS 在治疗 CM 和 MOH 中可能发挥作用。观察到的临床改善与 EEG α 节律的增强相结合。与假手术组相比,tDCS 组显着更高。结论 tDCS 在 CM 和 MOH 患者的管理中显示出辅助解毒作用。脑电图记录显示 α 节律显着增强,这可能与皮质-丘脑连接的潜在变化有关。意义 这项研究表明 tDCS 在治疗 CM 和 MOH 中可能发挥作用。观察到的临床改善与 EEG α 节律的增强相结合。与假手术组相比,tDCS 组显着更高。结论 tDCS 在 CM 和 MOH 患者的管理中显示出辅助解毒作用。脑电图记录显示 α 节律显着增强,这可能与皮质-丘脑连接的潜在变化有关。意义 这项研究表明 tDCS 在治疗 CM 和 MOH 中可能发挥作用。观察到的临床改善与 EEG α 节律的增强相结合。意义 这项研究表明 tDCS 在治疗 CM 和 MOH 中可能发挥作用。观察到的临床改善与 EEG α 节律的增强相结合。意义 这项研究表明 tDCS 在治疗 CM 和 MOH 中可能发挥作用。观察到的临床改善与 EEG α 节律的增强相结合。
