Low Calcium Levels Linked to Cognitive Decline, Study Shows
Maintaining sharp cognitive function as we age is a major concern for many.
New research from the Medical University of Lodz in Poland sheds light on a potential dietary factor influencing cognitive health: calcium intake. The study, published in the journal "Nutrients," reveals a significant connection between low blood calcium levels and poorer cognitive performance in individuals over 60.
While previous research has highlighted the importance of magnesium for cognitive function in older adults, this study dives deeper by directly measuring both calcium and magnesium levels in participant’s blood. This objective approach avoids the potential for inaccuracies found in relying solely on questionnaires about dietary intake.
The researchers examined 1,220 participants over the age of 60, including 876 women and 344 men. Participants provided blood samples while hospitalized, and underwent cognitive function assessments.
The findings confirmed that increasing age and a history of heart failure were associated with poorer cognitive performance. Notably, individuals with lower blood magnesium or calcium exhibited lower scores on cognitive tests.
Interestingly, even those with normal magnesium levels but low calcium levels displayed signs of cognitive decline. This reinforces the importance of adequate calcium intake for optimal brain function.
The study also found a correlation between low blood magnesium and calcium levels and depression, suggesting a crucial role for these minerals in maintaining mental well-being.
"These findings underscore the need to monitor the nutritional status of older adults to prevent cognitive decline," emphasized a nutrition expert commenting on the study.
They further suggested that supplementing with calcium and magnesium-rich foods, such as dairy products, could be beneficial in addressing potential deficiencies.
"Aging, cardiovascular disease, and chronic inflammation can all increase the risk of "cognitive deficiency." When memory, thinking, and problem-solving abilities decline, people have difficulty completing work or household chores accurately and efficiently, and may even become disoriented or lose their memory," the original study explains.
This research highlights the importance of a balanced diet rich in calcium and magnesium for supporting cognitive health throughout life.

## Low Calcium Linked to Cognitive Decline: An Expert Weighs In
New research suggests that insufficient calcium levels may be a contributing factor to cognitive decline in older adults. A recent study published in the journal “Nutrients” by the Medical University of Lodz in Poland found a direct correlation between low blood calcium levels and poorer cognitive performance in individuals over 60. This groundbreaking study adds to the existing body of knowledge about the importance of nutrition for brain health.
To better understand the implications of these findings, we spoke with **Dr. Eleanor Vance, a registered dietitian and certified geriatric specialist** and **Dr.James Carter, a neuroscientist specializing in cognitive aging.** Together, they shed light on the link between calcium, cognitive function, and practical steps to promote brain health.
### The Calcium-Brain Connection
**World Today News:** Dr. Vance, can you explain why calcium is so significant for brain function, notably as we age?
**Dr. Vance:** Calcium plays a vital role in many bodily functions, including nerve cell dialogue. As we age,our ability to absorb and utilize calcium can decline,potentially affecting cognitive processes like memory,attention,and problem-solving.
**World Today News:** Dr. Carter, what does the research on low calcium and cognitive decline tell us about the underlying mechanisms at play?
**Dr. Carter:** The exact mechanisms are still being investigated, but we know that calcium is essential for synaptic plasticity, the brain’s ability to adapt and form new connections. Deficiencies may impair this plasticity, leading to cognitive decline.
### Beyond Magnesium: Unveiling the Role of Calcium
**World Today News:** previous research has focused on the role of magnesium in cognitive function.How does this study contribute to our understanding?
**Dr. Vance:** This study is significant because it directly measured calcium and magnesium levels in the blood, rather than relying on dietary questionnaires. This objective approach provides stronger evidence for the link between low calcium and cognitive decline, even in individuals with normal magnesium levels.
Dr.Carter, are there other nutritional factors that should be considered alongside calcium and magnesium for brain health?
**Dr. Carter:** Absolutely. A balanced diet rich in antioxidants, omega-3 fatty acids, and B vitamins is crucial for protecting brain cells from damage and supporting cognitive function.
### Mitigating risk: Practical Steps for Brain Health
**World Today News:** Dr. Vance, what practical advice can you offer our readers to ensure adequate calcium intake and potentially reduce the risk of cognitive decline?
**Dr. Vance:** Incorporate calcium-rich foods into your daily diet, such as dairy products, leafy greens, fortified cereals, and almonds. If you have concerns about meeting your needs, talk to your doctor about calcium supplementation.
**World Today News:** Dr. Carter, are there any lifestyle changes that can protect against cognitive decline, along with diet?
**Dr. Carter:** Regular physical activity, mental stimulation through learning new things, and social engagement have all been shown to benefit cognitive health.
### Looking Ahead: The Future of Nutrient-Focused Brain Health
**World today News:** Dr. Vance, what are your predictions for the future of research in this area?
**Dr. Vance:** I anticipate seeing more research exploring the interaction of various nutrients and their combined impact on cognitive health. This will allow for more personalized dietary recommendations for individuals at risk of cognitive decline.
**Key Takeaways:**
Maintaining adequate calcium levels is crucial for optimal brain function and may play a role in preventing cognitive decline. Ensure you consume a balanced diet rich in calcium-rich foods, and consult with your doctor about supplementation if needed.
