Migraines are not fully understood

Despite migraine being one of the most common neurological conditions and affecting over a billion people1 around the world, we don’t fully understand what causes the migraine but it is thought it may be linked to temporary changes in certain chemicals, electrical activity or blood vessels in the brain.
While the exact causes may not be known, we do know that there are certain risk factors that make you more likely to get migraine and that some things may trigger a migraine.


Migraine risk factors:

  • Being female – probably due to hormonal changes women face during their different life stages
  • A family history of migraine – migraine has a genetic link in some people
  • Age – migraine peaks during your 30s

Common migraine triggers include:

Certain foods or drinks
Being stressed
Being tired
Hormonal changes –
such as starting your
period or menopause
Vigorous exercise

It is not always easy to identify migraine triggers as attacks may be linked to one or a number of things and are not the

same for everyone. Keeping a diary may be help reveal any possible migraine triggers you have.
