ABSTRACT Familial hemiplegic migraine (FHM) is an autosomal dominant type of migraine and probably represents the most extreme end of migraine with aura. Reduced magnesium facilitates the development of spreading depression and possibly aura. Cellular magnesium levels are under genetic control. We hypothesized that FHM patients would have significantly reduced intracellular magnesium levels. We determined intracellular and plasma magnesium levels in blood of 38 afflicted and 11 non-afflicted members of three families with FHM and in 32 migraine patients (9 with and 23 without aura) and 32 age and sex matched healthy controls. We found no significant differences between the magnesium levels in the five study groups. We conclude that reduced blood magnesium is unlikely to be related to migraine pathophysiology.

    ABSTRACT: Decreased serum and intracellular levels of magnesium have been reported in patients with migraine. It has been suggested that magnesium may play an important role in the attacks and pathogenesis of headaches. We measured ionized magnesium cyclic AMP (adenosine monophosphate), and cyclic GMP (guanosine monophosphate) in platelets of patients with migraine in patients with tension-type headache, and in healthy controls. The platelet level of ionized magnesium from patients with tension-type headache was significantly lower than the levels from the other two groups. The platelet level of cyclic AMP from patients with migraine was higher than those from the other groups. We found no significant differences in the platelet cyclic GMP levels among the three groups. It is suggested that reduced platelet ionized magnesium in patients with tension-type headache is related to abnormal platelet function, and that increased platelet cyclic AMP in patients with migraine is related to alteration of neurotransmitters in the platelet.

    ABSTRACT: Introduction: Nowadays, many studies consider a role for magnesium and calcium in pathophysiology and treatment of migraine. We evaluated serum ionized magnesium and calcium level in migraineurs -during interictal period-and control group. Methods: Migraineurs -according to the IHS criteria-enrolled in this study. Serum Mg²+ and Ca²+ level were determined by atomic absorption spectrophotometry. Mean values were compared, using t-test. Results: 40 migraineurs and 40 healthy subjects (34 (85%) female and 6 (15%) male in each group) enrolled the study with mean age of 34.8±9.9 and 35.7±9.1 years, respectively. There were no significant difference between Mg²+ levels in cases vs. healthy subjects (1.55±0.27 vs. 1.55±0.29 meq/l) but serum Ca²+ level was lower in healthy subjects. (8.04±1.18 vs. 7.56±0.82 meq/l, P<0.05). Migraineurs without aura had lower serum Mg²+ level (1.56±0.26 vs. 1.76±0.24 meq/l) and higher serum Ca²+ level (8.10±1.23 vs. 7.64±0.65 meq/l) than with aura migraineurs. Migraineurs with "monthly attack rate ≥4" had lower Mg²+ and Ca²+ level (1.48±0.23 vs. 1.58±0.29 meq/l) and (7.95±0.42 vs. 8.09±1.85 meq/l) than those with lower attack rate. Females whose attacks aggravated by menstruation had lower serum Mg²+ and Ca²+ level in comparison with those their attacks didn't aggravate by menstruation (1.46±0.25 vs. 1.77±0.25 and 7.77±0.59 vs. 8.80±2.77, P<0.05). Conclusion: In our study, severity of migraine had correlation with reduced serum Mg²+ and higher Ca²+ level which confirms the role of reduced magnesium level on lowering the threshold of attacks. Also, lower Mg²+ and higher Ca²+ level in migraineurs without aura could exhibit a demonstrable calcium channelopathy, but also raises questions about possibility of different mechanisms for "with and without aura" migraine. However, it seems that further studies with larger sample size and intra cellular (RBC and monocyte) Mg²+ assessment, is needed. Introduction Headache is a prevalent complaint among clinics clients. (1) It strikes 1 out of each 3 persons all over the world in at least one stage of life. (2) Approximately, 90% of cases with recurrent headaches are primary in etiology like Migraine, tension and cluster headaches. (3) Among them common migraine is the most prevalent one. (4) In America migraine prevalence is 6% in males and 17.6% in females. (3) Migraine is a chronic disease by episodic attacks that also induces levels of disability during attacks intervals. (3) In the U.S reduction of worker productivity for headache is about 6.5-17.2 billions dollars annually, in comparison to 2.6 for diabetes. (5) Despite the importance and prevalence of migraine, unfortunately our knowledge is limited about it and in spite of the marked progression on pathophysiology and pharmacology of migraine, which have been made during recent 15 years, its mechanism is still unknown (3) and different theories has been given about it's pathogenesis, genetics and neurotransmitters, involved in it, that some are the base of the new treatments. Some have categorized headache in hyper-excitability syndrome and have considered a role for the variable calcium and magnesium body level in its etiology. (5) During recent years, some investigators, has attached a great importance to the role of magnesium in pathophysiology and treatment of migraine. Among different investigations on Mg2+ and migraine pathogenesis, there are different results. Some has detected decreased level of serum and RBC Mg2+ level during attacks intervals (6) and some in migraine attacks. (7) While in other studies there were no significant differences in platelet ionized magnesium level (8) and also serum Mg2+ level (9) among migraineurs and control group. Despite other studies, in the latter study, it's being concluded that Mg2+ level decrement dose not have any role on Migraine pathophysiology. (9) These discrepancies and disagreement continues to magnesium therapeutic role in migraineurs. Some believe on its positive therapeutic role in acute attacks (7) and also during attacks intervals (10,11) and some investigators are suspicious to its preventive role. (12) In this study we compared serum magnesium and calcium level in migraineurs, during interictal period and in control group.

    ABSTRACT: Migraine is one of the most common neurological disorders that affects young people, causing a considerable degree of disability in the active population, with an enormous consequent socio-economic impact. Despite intensive research, the pathomechanism of migraine is not completely understood and its fully effective therapy remains to be achieved. A number of experimental studies have implicated the importance of magnesium ion in the pathophysiology of this condition. Magnesium has been also administered for both prophylactic and acute therapy in migraine, but the question of its efficacy has not been studied adequately. The data available suggest that magnesium has a potential role in the prophylaxis, but the results in acute therapy are far less convincing. With a good side effect profile, magnesium is a relatively safe drug with a possible beneficial effect in the prophylaxis of migraine headache, and it may have its niche in the treatment of migraine patients. However, the current medical evidence that has accumulated and the fact that there are far more effective treatment possibilities clearly indicate that this drug is definitely not to be used by every migraineur.
