OBJECTIVES We investigated (1) a possible relationship between the functional activity of the endocannabinoid system and the facilitation of pain processing in migraineurs with medication-overuse headache, and (2) the effect of withdrawal treatment on both. BACKGROUND The endocannabinoid system antinociception effect includes prevention of nociceptive(More)
Nitric-oxide donor glyceryl-trinitrate (GTN) modulates cerebral and spinal regions that are involved in migraine and pain processing. We hypothesized that in migraineurs, the susceptibility to develop a migraine attack after GTN administration should parallel with an high sensitivity to GTN-induced change in the pain processing at spinal level. We used the(More)
