Serum Magnesium Levels in Migraine Patients and Relationship of Phosphene Appearance With Occipital Cortex Transmagnetic Stimulation

Purpose: In this study we investigate the occipital cortex excitability by using transmagnetic stimulation in 30 migraine patients(15 with aura, 15 without aura) and 31 healty volunteer person and relation of this excitability with serum Mg levels Material and Method: We used Medelec Sapphire 4ME device to stimulate the occipital cortex. We also estimate the phosphene threshold and the serum Mg levels of patient and control group.Results: In migraneus patients phosphene appereance rate was not found to be different from the control group but the phosphene appereance threshold was lower significantly. Serum Mg levels was similar between two groups and there was no relation between Mg levels and phosphene appereance threshold in migraine patients.Conclusion: Our study showed the increased occipital cortex excitability in migraine patients however we didn't find any relation between serum Mg levels and increased occipital cortex excitability.
