Migraine & neuroinflammation
In plain language
A 35-year-old man has suffered from migraine for years. The attacks come unpredictably: throbbing headache, nausea, sensitivity to light. Medication relieves the pain, but does not prevent the attacks. Why does migraine remain so elusive? Because it is not a pure ‘headache problem’, but a storm that rages on several fronts at once: in the nerves, the immune system and the microbiome.
Beneath an attack lie several sparks. Neuroinflammation — small inflammatory reactions around blood vessels — irritates the trigeminal nerve, the main nerve behind migraine. Histamine peaks, released by mast cells, amplify the headache. Faltering mitochondria make the brain more sensitive, and disrupted gut flora influences serotonin and the way pain is modulated. Because all these factors weigh differently in each person, every migraine is different. That explains why one pill is rarely the whole story — and why insight into your own pattern is so valuable.
The science behind
In modern neurology, migraine is understood as a systemic, multifactorial condition. A review in The Lancet Neurology describes how attacks arise from an interplay of nerve pathways, immune reactions and hormonal fluctuations, with the trigeminovascular route as the central axis. Neuroinflammation plays a key role in this: low-grade inflammatory reactions around the blood vessels in the meninges activate the trigeminal nerve and set the pain cascade in motion. In this reading, migraine is not an isolated headache signal, but an expression of a broader deregulated system.
Several mechanisms feed that storm. Work in Frontiers in Immunology shows that mast cells and histamine amplify the neuroinflammation and thereby intensify the headache. Research in The Journal of Headache and Pain links changes in the gut microbiome to the onset of migraine with and without aura, via effects on serotonin, pain modulation and inflammation along the gut-brain axis. Analyses in Nutrients also point to disrupted energy metabolism: faltering mitochondria lower the threshold above which the brain slips into an attack. In this way inflammation, histamine, microbiome and energy household interlock.
The common thread is co-metabolism: whether someone ends up in the storm often or rarely arises from the interplay of DNA, microbiome, metabolites and lifestyle together. Gene variants colour the predisposition for histamine breakdown, inflammatory sensitivity and energy metabolism, but nutrition, sleep, stress and microbiome balance determine what you do with that predisposition. Migraine thus becomes readable as a pattern of biological routes — and it is precisely this that makes it possible to recognise triggers and break the pattern step by step. This reading is supportive and observational — not a medical diagnosis.

Frequently asked questions
- Is migraine just a bad headache?
- No. Migraine is a systemic condition in which neuroinflammation, histamine, mitochondria and the gut-brain axis interact — not merely a pain in the head.
- What is neuroinflammation in migraine?
- Small inflammatory reactions around blood vessels in the meninges that activate the trigeminal nerve and thereby set the pain cascade in motion.
- What does my gut have to do with migraine?
- Via the gut-brain axis the microbiome influences serotonin, pain modulation and inflammation; changes in it are linked to migraine with and without aura.
- Why doesn't medication always prevent my attacks?
- Because one pill rarely reaches all routes at once. Insight into your own pattern — inflammation, histamine, microbiome, energy — helps you recognise triggers and break the pattern.
