Potential Migraine Causes

It is not clear what causes migraines. It is thought that some chemicals in the brain increase in activity and parts of the brain may then send out confusing signals which cause the symptoms. The exact changes in brain chemicals are not known and it is not known why people with migraine develop these changes.


Fluctuating levels of hormones may also be
a cause of a migraine attack.


Migraines can be triggered by several factors, both inside and outside the body. These triggers vary by individual. Go to our Migraine Triggers page to find out more.

Who is affected by migraines?

You are not alone, there are approximately 8 million migraine sufferers in the UK. It is the most common neurological condition in the developed world.

Migraines affect 1 in 5 women and 1 in 15 men in the UK. A reason for women experiencing migraines more frequently than men might be hormonal changes in the body, which is why some women may experience migraine attacks around the time of their period.

Migraines can occur at any stage in life, however, people mostly experience their first migraine before they are 40 years old.
