Magnesium is known to block the NMDA receptor. The available evidence suggests that up to 50% of patients during an acute migraine attack have lowered levels of ionized magnesium (Ramadan et al., 1999). Erythrocytes and lymphocytes magnesium concentrations are significantly lower in migraine patients as compared to controls (James et al., 2000). Infusion of magnesium results in a rapid and sustained relief of an acute migraine in such patients (Mauskop et al., 1995). However, it should be mentioned that magnesium concentration has an effect on serotonin receptors, nitric oxide synthesis and release, and a variety of other migraine-related receptors and neurotransmitters (Mauskop and Altura, 1998). It is well known that reduced magnesium facilitates the development of SD in animal models and human tissues (Mody et al., 1987). Intravenous magnesium as well as the NMDA receptor antagonist MK-801 significantly reduced the frequency of SD evoked by cortical KCl application in rats. On the other hand, SD affects magnesium metabolism in the central nervous system (van der Hel et al., 1998). The magnesium sulphate anesthesia was considerably shortened approximately four times by CSD in functional decorticated mice in comparison with control animals (Bohdanecky and Necina 1963).

Magnesium is known to block the NMDA receptor [271]. The available evidence suggests that up to 50% of patients during an acute migraine attack have lowered levels of ionized magnesium [348,455]. Erythrocytes and lymphocytes magnesium concentrations are significantly lower in migraine patients as compared to controls [426]. Infusion of magnesium results in a rapid and sustained relief of an acute migraine in such patients [270]. However, it should be mentioned that magnesium concentration has an effect on serotonin receptors, nitric oxide synthesis and release, and a variety of other migraine-related receptors and neurotransmitters [269]. It is well known that reduced magnesium facilitates the development of SD in animal models and human tissues [16,291]. Intravenous magnesium as well as the NMDA receptor antagonist MK-801 significantly reduced the frequency of SD evoked by cortical KCl application in rats [439]. On the other hand, SD affects magnesium metabolism in the central nervous system. The magnesium sulphate anesthesia was considerably shortened approximately four times by CSD in functional decorticated mice in comparison with control animals [35].
