There's nothing quite like the misery of a migraine. If you're among the nearly 20 percent of women who suffer from these headaches, you know how painful they can be. But there's new reason for hope: Researchers are finally shedding light on what was once a mostly misunderstood medical phenomenon. 没有什么比偏头痛更令人痛苦。20%的女性都患有偏头痛，如果你也是其中一员，那你便会对偏头痛深有体会！现在，希望来了：研究员终于揭示了这个一度被误解的医学现象。 "Even just 10 years ago, doctors thought migraines were a blood vessel problem," explains Geoffrey Eubank, MD, the medical chief of general neurology at OhioHealth in Columbus. "Now we know they are neurological, meaning they're caused by a burst of cellular activity in the brain. And that has contributed to innovations in treatment." "即便是10年前，医生都认为偏头痛是一种血管疾病，"哥伦布市俄亥俄医疗机构（OhioHealth）普通神经病学的首席医师杰弗里·尤班克博士说道。"现在我们都知道，偏头痛是神经系统疾病，也就是说偏头痛是由大脑中细胞活动的爆发引起的。这种认知也促进了治疗手段的创新。" This is especially good news for women, since we're three times as likely as men to get a migraine. You could blame estrogen, though the link between the hormone and brain pain isn't entirely clear. "Fluctuations in estrogen appear to trigger migraines," says Dr. Eubank, which is why some women are more likely to get a migraine right before their period, during or after pregnancy, or during menopause. |
