About

The purpose of this study is to determine whether reduced frequency of migraine attacks are associated with signal alternation and connectivity of cerebral cortex.

Full description

Patients with migraine show reduced cortical thickness in regions subserving pain processing, and it is related to increasing headache frequency. In the past, only one study has shown a reversibility consequence of chronic nociceptive transmission, which normalizes when the pain is adequately treated. However, little is known whether these changes predispose to migraine or represent the effect of repeated migraine attacks. Our region of interest is reduced frequency of migraine attacks are associated with reversibility of signal alternation and functional connectivity of cerebral cortex.

In 30 migraineurs with 8-14days with headache per months who already performed brain magnetic resonance imaging will be recruited. Treatment medications such as frovatriptan and topiramate will be used for 6 months. After 6 months, follow-up brain magnetic resonance imaging will be performed.

The primary outcome is the longitudinal changes in functional connectivity in pain-processing/modulating brain regions. The secondary outcome is following: 1)longitudinal changes in structural and morphological alterations in brain regions of pain processing; 2)structural, morphological, and functional correlates of treatment response; 3)changes in monthly migraine days, migraine frequecies, headache days, and headache frequencies after treatment; 4)responses to acute migraine treatment.
