Think back to your last migraine…
What were you doing just before it started?
You probably weren’t doing anything too different to what you usually do.
So what caused your migraine to start up?
The Causes of Migraines are Unknown
When most people want to know about migraine causes, what they’re usually looking for are the triggers that bring on migraines.
Unfortunately, the true underlying mechanism that starts migraines still isn’t known.
I know that doesn’t help much, but when it’s worked out, it’s going to make you and a lot of other people very happy.
There is some valid research on what is thought to be the cause of migraines but it hasn’t been completely proven just yet.
The Theory of Migraine Causes
It used to be thought that changes in blood flow to the brain caused migraines.
This is no longer the case.
The most recent theories about what causes migraines relate to your central nervous system.
Your central nervous system contains your brain and spinal cord and controls all the activity in your entire body.
It’s now thought that chemical changes in the brain are the major contributors to the start of your headache.
Specifically a chemical known as serotonin.
Serotonin’s role is to reduce the perception of pain in your central nervous system. When there is a reduction in serotonin in your brain it can be a large factor in starting your migraine.
Interestingly enough, serotonin continues to decrease after your migraine starts. This causes the release of substances which travel to the protective layer of your brain and cause migraine pain.
The Causes Of Migraines May Be From The Neck
In your upper neck are 3 nerves known as cervical spinal nerves and another important nerve known as the trigeminal nerve.
These nerves make up a column known as the trigeminocervical nucleus (I know…Not the easiest name to remember!)
The nerve fibres in the trigeminocervical nucleus have a role in decreasing the pain signals going into your brain.
Your brain has a threshold which limits your perception of pain.
When these nerves stop functioning correctly the threshold decreases. This allows pain to come on a lot quicker and leads to pain referral in the head, eyes, face and neck…otherwise known as some of the symptoms of migraines.
It’s starting to be shown that people who suffer from migraines have a lower threshold in their brain to begin with than non-sufferers.
Theories Aren’t Always Right…But They Can Be!
Like stated above, these migraine causes are not proven to be the definitive reason for your migraines.
But they very well could be!
