Plasma glucose increases during spontaneous migraine attacks


Key clinical point : Plasma glucose level increases during spontaneous migraine attacks, and the increase is independent of the presence of aura symptoms and pain intensity.

Main finding : Plasma glucose levels were higher in the ictal phase than in the interictal phase of migraine (mean, 98.83 vs. 88.63 mg/dL; P = .0014) after adjusting for diurnal variation. The attack-related elevation in plasma glucose level was not influenced by pain intensity or the presence of aura symptoms.

Study details : In this study, plasma glucose levels were measured during and outside of spontaneous attacks of migraine in 31 patients (13 with aura and 18 without aura).

Disclosures: The study was funded by the Lundbeck Foundation, the Novo Nordisk Foundation, the University of Copenhagen, the Research Foundation of the Capital Region of Denmark, and the Danish Council for Independent Research-Medical Sciences. Faisal Mohammad Amin and Anders Hougaard reported receiving personal fees and/or honoraria from multiple pharmaceutical companies.
