Magnesium concentration in brains from multiple sclerosis patients.

|March 1, 1990
Summary
Multiple sclerosis (MS) patients exhibit significantly lower magnesium levels in brain and organ tissues compared to controls. This reduction, particularly in central nervous system white matter, may impact MS pathogenesis.
Area of Science:
- Neuroscience
- Biochemistry
- Pathology
Background:
- Multiple sclerosis (MS) is a chronic inflammatory disease affecting the central nervous system (CNS).
- Metal metabolism, including magnesium (Mg) levels, is increasingly recognized as a potential factor in neurodegenerative processes.
Purpose of the Study:
- To investigate and compare magnesium concentrations in CNS and visceral organs between patients with multiple sclerosis and healthy controls.
- To explore the potential role of magnesium dysregulation in the pathogenesis of multiple sclerosis.
Main Methods:
- Autopsy samples from 4 MS patients and 5 controls were analyzed.
- Magnesium content was quantified in 26 CNS tissue sites and major visceral organs (liver, spleen, kidney, heart, lung) using inductively coupled plasma emission spectrometry.
Main Results:
- Significantly lower average Mg concentrations were found in CNS tissues and most visceral organs of MS patients compared to controls.
- The most pronounced Mg reduction in MS patients was observed in CNS white matter, including demyelinated plaques.
Conclusions:
- Reduced magnesium levels in CNS and visceral organs are associated with multiple sclerosis.
- The precise role of these magnesium deficits in the demyelinating process of MS requires further investigation into metal metabolism and MS pathogenesis.
