THE ROLE OF MAGNESIUM DEFICIENCY AND ITS SUPPLEMATION IN DISEASES OF CENTRAL NERVOUS SYSTEM. REVIEW

Abstract

Relevance. Anti-depressant effects of NMDA receptor antagonists have been proven, a close association between low levels of magnesium in the blood and depression. Therefore, in recent years, antidepressant properties of magnesium are actively studied in animal experiments. Objective: To review modern literary sources about the role of magnesium deficiency in the pathogenesis of diseases of the central nervous system. Materials and methods. Searching for a depth of 12 years at Scopus, Google Scholar. Results. The results of experimental and clinical researches pointed out on association between low level of magnesium in hair, liquor, brain with higher risk of development dementia, depression and anxiety. An additional supplementation with magnesium in patients associates with decreasing risk of ischemic stroke and dementia, in pregnancy – provides neuroprotection of fetus, in case of depression increases effectiveness of antidepressants, in brain injury associates with faster recovery of cognitive functions, in migraines - with decreasing in the frequency of attacks and improvement of the quality patients’ lives, in case of neuroleptic therapy - with the possibility of delayed appearance or absence of manifestations of drug parkinsonism. These changes are explained by antagonistic effects of magnesium on glutamate receptors, decreasing oxidative stress intensity as well as neural cell  apoptosis. Conclusion. Magnesium plays an important neuroprotective role.
