YOUR BRAIN
AND MIGRAINE
Migraine is far more than ‘just a bad headache’ – it is a neurological condition where the nerves in the brain become hyperactive and ignite a burst of electrical activity in the nerve cells, launching a cascade of events.
So, what exactly is happening in the brain to create such an excruciating storm of pain? In the latest clinical evidence, it is now clear that migraine starts with at least one trigger that doesn’t bother the typical brain — this could be stress, lack of sleep, hunger, or dehydration, amongst many others.
These triggers then cause hyperexcitability in certain areas of the brain, and it is this response that stops the brain from being able to control its electrical activity in a normal manner. This results in the electrical system misfiring and behaving erratically.
The consequence of this is a change in the level of blood flowing in and around the brain. This leads to the blood vessels become inflamed, which causes throbbing pain alongside other potential symptoms, such as nausea and sensitivity to light.
Unfortunately, migraine attacks can become more frequent over time as the brain rewires itself by creating new neural pathways.
In effect, the brain learns how to have migraine attacks.
