DENVER — There could also be a hyperlink between migraine and scientific endocannabinoid deficiency, a speaker mentioned on the American Headache Society’s annual scientific assembly.

“That is very odd, as a result of 2-AG is definitely the extra dominant endocannabinoid lipid, and it is expressed and made at 200-fold extra concentrated ranges than anandamide itself,” she mentioned.

Largent-Milnes and colleagues utilized preclinical fashions to know the hyperlink between migraine and endocannabinoid deficiency. They used medicine overuse fashions and measured periorbital withdrawal thresholds and endocannabinoid lipids.
