A study of 50 migraineurs has confirmed previous observations that sleep is a common way of ending the headache phase. 14 subjects could shorten attacks by going to sleep during the day for an average of 2 1/2 hours. Different methods used by patients to aid falling asleep are described. 47 of the 50 subjects had symptoms after the headache had gone--here called the recovery phase which can double the length of individual attacks. It is suggested that prodromata, some symptoms of the headache and recovery phases, as well as the therapeutic effect of sleep, indicate that migraine is primarily a neurological rather than a vascular disorder.
一项针对50名偏头痛患者的研究证实了之前的观察结果，即睡眠是结束头痛阶段的常见方式。14名受试者通过白天平均睡2个半小时能够缩短发作时间。文中描述了患者用来帮助入睡的不同方法。50名受试者中有47名在头痛消失后出现了症状——这里称之为恢复期，恢复期可能会使个体发作时间延长一倍。有人提出，前驱症状、头痛和恢复期的一些症状以及睡眠的治疗效果表明，偏头痛主要是一种神经疾病而非血管疾病。
