The Link Between Glutamate and Migraine

CNS Spectr. 2003 Jun;8(6):446-9. doi: 10.1017/s1092852900018757.

Abstract

Migraine pain-relay centers, including the trigeminal ganglion, trigeminal nucleus caudalis, and thalamus, contain glutamate-positive neurons, and glutamate activates the trigeminal nucleus caudalis. Glutamate is implicated in cortical spreading depression, trigeminovascular activation, and central sensitization. Glutamate receptor-subtype antagonists are effective in preclinical models of migraine, and in the clinic. These preclinical and clinical observations argue for a strong link between migraine and the glutamatergic system, a link that is important to further characterize in an effort to better understand migraine mechanisms and deliver effective therapies.
