慢性天天头痛症状包括慢性偏头痛。偏头痛转换为慢性天天头痛的原因仍不明。本研究旨在评估慢性偏头痛患者的热痛阈及手和面部ＣＯ2激光热刺激 (ＬＥＰＳ)的事件相关电位 ,并显示与皮层水平疼痛合成的功能障碍有关的伤害性脑反应的变化。结果与正常对照组以及无先兆偏头痛患者
Chronic headache symptoms include chronic migraine. The reason why migraine migrates to a chronic headache every day is still unknown.

Results were compared with the normal control group and patients without aura migraine
