The role of neuroinflammation in migraine: why brain inflammation can trigger a migraine attack
Share
Migraine is often seen as a blood vessel problem or "just a severe headache". But in reality, much more happens in the brain before the pain begins.
More and more research shows that inflammation in the brain (also called neuroinflammation) plays an important role in migraine. This inflammation makes the nervous system more sensitive and can cause a chain reaction that ultimately ends in a migraine attack.
To understand why this happens, we must first look at what neuroinflammation exactly is.
What is neuroinflammation?
Neuroinflammation literally means: an inflammatory response in the nervous system.
Normally, inflammation is a protective mechanism of the body. When there is damage, stress, or an infection, the immune system produces inflammatory substances to resolve the problem.
In the brain, this response is primarily carried out by microglia. These are immune cells that constantly "scan" the brain for damage or danger.
When these cells signal a problem, they produce inflammatory substances such as:
-
cytokines
-
prostaglandins
-
nitric oxide
These substances initially help repair damage. But when this reaction becomes too strong or too prolonged, it can actually cause problems.
And that's precisely where migraine often begins.
How inflammation causes a migraine attack
When inflammatory substances are released in the brain, this has multiple effects on the nervous system.
1. Brain cells become hyperexcitable
Inflammatory substances change the way neurons (brain cells) respond to stimuli. They make these cells more sensitive, causing them to react more quickly and intensely.
This can lead to a state where the brain becomes hyperexcitable.
2. A wave of brain activity occurs
When neurons become overstimulated, a phenomenon known as cortical spreading depression can occur.
This is a wave of electrical activity that slowly moves through the cerebral cortex. During this wave, brain cells first become extremely active and then temporarily exhausted.
This process is strongly associated with:
-
migraine with aura
-
neurological symptoms preceding migraine
3. Activation of the trigeminal nerve
The inflammatory substances then activate the trigeminal nerve, an important nerve that innervates the face and meninges.
This nerve transmits inflammatory signals to the blood vessels around the brain.
This results in:
-
dilation of blood vessels
-
increased sensitivity of pain nerves
-
release of additional inflammatory substances
This is when the pain phase of migraine begins.
How does inflammation in the brain occur?
Neuroinflammation rarely occurs out of the blue. It is often the result of various factors that chronically stress the nervous system.
According to insights from orthomolecular medicine, the following factors, among others, play an important role.
Chronic stress
Long-term stress increases the stress hormone cortisol. This hormone affects the immune system and can amplify inflammatory processes in the body.
In addition, stress keeps the nervous system constantly "on". This causes brain cells to become exhausted more quickly and more susceptible to inflammation.
Poor or disturbed sleep
During deep sleep, waste products are removed from the brain via the glymphatic system.
When sleep is disturbed:
-
inflammatory substances remain present longer
-
brain cells recover less well
-
the nervous system becomes more sensitive
Many people with migraine therefore notice that poor sleep can be a direct trigger for an attack.
Deficiencies in essential nutrients
Various nutrients are needed for a stable nervous system, such as:
-
magnesium
-
omega-3 fatty acids
-
antioxidants
-
B vitamins
When these substances are lacking, inflammatory reactions can occur more easily and the nervous system remains more sensitive to stimuli.
Intestinal problems and low-grade inflammation
There is a strong connection between the gut and the brain, also known as the gut-brain axis.
When the intestinal barrier is disturbed, inflammatory substances in the body can increase. These inflammatory signals ultimately also reach the brain and can contribute to neuroinflammation.
Signs that neuroinflammation plays a role
Many people with migraine recognize a number of typical signs that indicate an overstimulated and inflamed nervous system.
Common complaints include:
-
sensitivity to light and sound
-
brain fog or concentration problems
-
fatigue after mental exertion
-
neck and shoulder tension
-
aura phenomena
-
an "overstimulated" feeling in the head
These complaints arise because the nervous system is continuously in a sensitive, inflammation-prone state.
Why nutrition and supplements play an important role
Because neuroinflammation is strongly related to nutrients, energy production, and nervous system recovery, targeted support can make a big difference.
The migraine bundle from Optemuse focuses precisely on these processes.
The combination of Magnesium Citrate, Omega 3, and Sleep Support supports various mechanisms involved in migraine.
Magnesium Citrate
Magnesium is one of the most important minerals for the nervous system.
Many people with migraine appear to have lower magnesium levels, making neurons more sensitive to stimuli.
Magnesium helps with:
-
stabilizing nerve cells
-
regulating electrical signals in neurons
-
relaxing blood vessels
-
inhibiting inflammatory processes
In addition, magnesium plays an important role in the energy production of brain cells, making them less prone to exhaustion.
Omega-3
Omega-3 fatty acids are powerful anti-inflammatory agents.
They ensure that the body produces fewer pro-inflammatory substances and more anti-inflammatory molecules.
For migraine, this means that omega-3 can help with:
-
reducing neuroinflammation
-
stabilizing cell membranes of neurons
-
supporting healthy blood vessels
-
lowering stimulus sensitivity in the nervous system
This allows the brain to better cope with stimuli and stress.
Sleep Support
Sleep is one of the most important recovery mechanisms of the brain.
During deep sleep:
-
waste products are removed from the brain
-
neurons recover
-
the nervous system is rebalanced
When sleep is insufficient or superficial, inflammatory substances remain present in the brain longer.
Sleep Support supports:
-
a natural sleep rhythm
-
relaxation of the nervous system
-
deeper and more restorative sleep
This allows the brain to reduce inflammatory processes and recover better.
The power of the combination
What makes this bundle special is that the products simultaneously support various causes of migraine.
Magnesium stabilizes neurons.
Omega-3 inhibits inflammation.
Sleep Support helps the brain recover.
Together, they support the nervous system, reduce inflammatory processes, and increase the brain's excitability threshold.
And that can be an important step in reducing migraine.
If you have migraine, it is important to realize that an attack often doesn't just happen. It is usually the result of a nervous system that has been under prolonged stress.
By reducing inflammation in the brain and supporting the nervous system, you can help the body find more balance again. And from that balance, migraine can often gradually decrease.
