小编摘要:头痛是临床上常见的症状之一,通常是指局限于头颅上半部,包括眉弓、耳轮上缘和枕外隆突连线以上部位的疼痛。头痛的原因繁多,其中有些是严重的致命疾患,但病因诊断常比较困难.

 Migraineor Face Pain?

偏头痛还是脸部疼痛?


If you’ve ever had amigraine headache, you don’t need me to tell you it hurts. Doctors report that about twentymillion people suffer from serious headaches, and ten percent of these haveintractable pain–meaning it doesn’t go away. But here’s a surprise: the problem isn’t always a migraine.Sometimes very similar symptoms are caused by damage to a nerve of the face,which results in the nerve itself sending nonstop “ouch” signals.

What can be done?

A new treatment being tried out by a fewdoctors, including Dr. Robert Levy, a neurosurgeon at Northwestern MemorialHospital, involves zapping with electricity certain nerves that innervate theface. It’s like a marathon in which thousands of runners are crossing the BrooklynBridge. Someone sends up a firework nearby and for a moment all the distractedrunners stop and stare. By hitting the nerves with a mild electrical jolt, youcan “distract” the signal-carriers–that is, the pain signals stop crossing the nerves for as long asthe electrical charge is on.

So how to do that? Levy and others haveinserted a little battery under patients’ collarbones,connected it to a wire that runs under the scalp, and stuck the end directlyinto the misfiring nerve. Odd as it may sound at first, it works. Patientsreport that when the device is turned on they are pain-free, sometimes for thefirst time in years. This kind of nerve stimulation is still in its early days,but the results so far look very promising. For chronic headache sufferers, alittle wire can make for blessed peace of mind…not pain of head.



如果你曾经有过偏头痛的经历,就不需要我告诉你那有多痛苦。医生报告,大概有2千万人患有严重头痛,并且他们之中百分之十患有顽固性疼痛——那意味着疼痛不会消失。但医生们有一个惊奇发现:问题不总是偏头痛。有时,类似的症状是由脸部神经受损引起的,受损的神经会不间断地疼痛信号。

我们可以做些什么呢?

有几个医生正试验一种新的治疗,包括罗伯特莱维博士,他是西北纪念医院的一位神经外科医生,参与到用电流破坏那些刺激脸部的神经。就像一场马拉松,数千名奔跑的人穿越布鲁克林大桥。有的人在附近放烟火,这会儿所有的跑步的人都停下来看。通过一个轻度的电力震动击打神经,你就可以转移信号载波——就是说,疼痛信号停止穿越神经,只要电荷一直处于连接状态。

那么如何做到这一点呢?莱维和其他医生在患者锁骨下面插入了一个小电池,并与头皮下的电线连接,然后把末尾插入神经。起初也许听起来有点奇怪,它能管用。患者报告说,当设备接通时,他们感觉不到疼痛,这是多年来第一次。这种神经刺激仍处于初期,但到目前为止的结果看起来是很有前途的。对慢性头痛患者来说,一小节电线得到内心的平静……而不是头痛。
