A deficiency in blood magnesium levels might correlate with an increased likelihood of developing dementia and other severe health issues, according to findings from Taiwanese researchers. This large-scale study’s outcomes have been published in the journal Frontiers in Nutrition.
The research team examined data from over 325,000 individuals aged 50 and above, sourced from the international TriNetX medical database. The analysis revealed that individuals whose magnesium levels were recorded below 1.7 mg/dL on two separate occasions within a year exhibited a 33% greater risk of developing dementia compared to participants with normal levels.
The most significant association was observed with vascular dementia, where the probability of its development escalated by 63%. Furthermore, a magnesium deficit was linked to a higher risk of stroke and mortality from all causes.
The study’s authors indicate that magnesium plays a crucial role in the nervous system’s function, maintaining vascular health, and metabolic processes. A lack of this mineral can impair brain blood supply, exacerbate inflammation, and disrupt nerve cell communication, potentially contributing to cognitive impairment over time.
These findings remained consistent across participants regardless of their age or gender. A key strength of this study was its use of repeated magnesium measurements, enabling researchers to assess prolonged mineral deficiency rather than just temporary fluctuations in its levels.
The scientists also noted that excessively high magnesium levels might also carry adverse health consequences. This suggests a potential “U-shaped” effect, where risks are elevated by both insufficient and excessive amounts of the mineral.
The researchers propose that monitoring magnesium levels could serve as a method for early identification of individuals at heightened risk of cognitive decline. In the future, such data could inform the development of preventive strategies focusing on diet and maintaining optimal mineral balance.
