Brainstem sensitisation and migraine: what does the term actually tell you?
Melbourne Headache Solutions. First published 17 March 2021. Recovered and editorially updated 28 October 2026 from our archived resource. This is general education, not an individual diagnosis.
Quick answer
Sensitisation describes changes in how the nervous system responds to signals. It can help explain aspects of pain, but it is not a complete diagnosis or proof that your neck caused migraine. A treatment plan still needs your history, examination and appropriate medical assessment.
Why has this explanation been updated?
The archived MHS article used brainstem sensitisation as a single underlying explanation for chronic headache and migraine. This refreshed version keeps the question but avoids presenting one mechanism as the answer to every case.
Migraine involves complex nervous-system processes. A concept used to explain pain does not establish which treatment a particular person needs, nor does it show that a joint is stuck or must be repositioned.
What symptoms should I describe?
Tell your clinician if ordinary touch, brushing hair or wearing something against the scalp becomes painful, and whether that happens during attacks or between them. This is useful information for the headache assessment.
Do not use a symptom description to diagnose sensitisation yourself. New numbness, weakness, visual loss or other neurological changes need appropriate assessment rather than a reassuring mechanism-based explanation online.
What questions should I ask about treatment?
Ask how the explanation relates to your findings, which outcomes the treatment aims to change and when it will be reviewed. Avoid assuming that a temporary treatment response proves a particular theory.
MHS can discuss relevant headache and physical findings alongside medical care. Medicines, activity advice and physical treatment may have different roles; none should be promised to switch off every migraine by correcting one universal cause.
