New Study Reveals Optimal Magnesium Levels Could Lower Dementia Risk
Advertisement
In a recent study published in the journal Advances in Nutrition, scientists examined whether different measures of magnesium levels, including biomarkers, dietary intake, and supplements, were associated with cognitive health and neurological functioning in adults.
Dementia in older adults significantly contributes to disability, health burdens, and mortality, affecting memory, behavior, and daily activities. With over 55 million people worldwide diagnosed, the prevalence and healthcare costs are expected to rise due to the aging population.
Targeting modifiable risk factors like stress, depression, vascular health, and lifestyle is crucial to reducing dementia's incidence and progression. Electrolytes, particularly magnesium, are vital for neurological health. Magnesium deficiency has been linked to memory impairments and Alzheimer’s disease, though findings from longitudinal studies remain inconsistent.
Magnesium supports neuronal health by reducing inflammation and oxidative damage and preserving the integrity of the blood-brain barrier. It inhibits the activity of the N-methyl-D-aspartate (NMDA) receptor and decreases calcium influx, thereby reducing excitotoxic damage. Additionally, magnesium is crucial for maintaining myelinated axons and the myelin sheaths on neurons.
