Answer

Another theory proposes that deficiency of magnesium in the brain triggers a chain of events, starting with platelet aggregation and glutamate release and finally resulting in the release of 5-hydroxytryptamine, which is a vasoconstrictor. In clinical studies, oral magnesium has shown benefit for preventive treatment and intravenous magnesium may be effective for acute treatment, particularly in certain subsets of migraine patients.
