Triggers Migraine is a biological disorder of the central nervous system.
Attacks are more likely to occur when the migraineur is exposed to one or more triggering factors.
A trigger is an internal or external influence that activates or aggravates a migraine attack. No two people have exactly the same triggers, although there are some more common ones. Because people afflicted with migraine have a lower threshold to these influences, it is important to identify triggers and reduce or eliminate their impact as much as possible. If you have an easy time identifying your triggers, you will likely find it easier to manage your migraine attacks. Many people find a combination of triggers set off their attacks, while one trigger alone may not.
