Now, it appears more likely that migraines 'hijack' the brain's normal pain circuitry, says Dr. Dodick. The brain's normal pain-sensory system, in which nerve endings send messages to the brain about a threat, goes awry in migraines.
多迪克说,现在看来,更有可能是偏头痛“拦截”了大脑的正常疼痛回路。在大脑正常的疼痛感知系统里,神经末梢会将威胁信息发送给大脑,偏头痛发生时这个系统就会出错。
Experts disagree about how a migraine is triggered, but the trigeminal nerve - an important pathway that carries sensory information about the face - and its connections to numerous other nerves and the brain appear to be responsible for transmitting the pain.
偏头痛是如何引发的?专家们对此意见不一,但是三叉神经(传递面部周围感官信息的重要途径)以及它与其它各种神经和大脑的连接神经似乎是传递疼痛的介质。
Researchers also have isolated certain genes that might be linked to a predisposition for migraines, Dr. Dodick says.
多迪克医生说,研究人员已经把某些与易患偏头痛体质相关的基因分离出来。
Triptans, which promote blood-vessel constriction and inflammation, block the release of CGRP in the trigeminal nerve. While CGRP does aid the blood-vessel dilation process, its role activating the nerves in the brain appears to be the key when it comes to migraine pain.
