OBJECTIVE: Chronic migraine (CM) is often associated with chronic tenderness of
pericranial muscles. A distinct increase in muscle tenderness prior to onset of
occipital headache that eventually progresses into a full-blown migraine attack
is common. This experience raises the possibility that some CM attacks originate
outside the cranium. The objective of this study was to determine whether there
are extracranial pathophysiologies in these headaches. METHODS: We biopsied and
measured the expression of gene transcripts (mRNA) encoding proteins that play
roles in immune and inflammatory responses in affected (ie, where the head hurts)
calvarial periosteum of (1) patients whose CMs are associated with muscle
tenderness and (2) patients with no history of headache. RESULTS: Expression of
proinflammatory genes (eg, CCL8, TLR2) in the calvarial periosteum significantly
increased in CM patients attesting to muscle tenderness, whereas expression of
genes that suppress inflammation and immune cell differentiation (eg, IL10RA,
CSF1R) decreased. INTERPRETATION: Because the upregulated genes were linked to
activation of white blood cells, production of cytokines, and inhibition of
NF-?B, and the downregulated genes were linked to prevention of macrophage
activation and cell lysis, we suggest that the molecular environment surrounding
periosteal pain fibers is inflamed and in turn activates trigeminovascular
nociceptors that reach the affected periosteum through suture branches of
intracranial meningeal nociceptors and/or somatic branches of the occipital
nerve. This study provides the first set of evidence for localized extracranial
pathophysiology in CM. Ann Neurol 2016;79:1000-1013.
