Trigeminal-Targeted Treatments in Migraine: Is 60% the Magic Number?

Trigeminal-targeted treatments (TTTs), the most specific and selective therapeutic migraine approach to date, are effective in approximately 60% of patients regardless of treatment type or mechanism, at least if used alone. Sixty percent is also the proportion of migraineurs who develop migraine-like episodes following experimental intravenous administration of trigeminal neuropeptides and roughly 60% is the percentage of patients with a unilateral migraine tracing the area of cutaneous distribution of the trigeminal ophthalmic branch. Hence, mechanisms other than the trigeminovascular activation are probably involved in the 40% of migraineurs who do not respond to TTTs. A closer cooperation between clinical and basic neuroscientists is needed to explore migraine models because only a careful appraisal of migraine endophenotypes may help to unravel their underlying multifaceted pathophysiological machinery.
