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.

## Can Low Calcium Levels Speed Up Cognitive Decline? Experts Weigh In
New research has drawn a direct link between insufficient blood calcium levels and poorer cognitive function in individuals over 60. This finding, published in the journal “Nutrients,” adds another layer to the growing understanding of how nutrition plays a vital role in maintaining brain health as we age. To delve deeper into the implications of this study, we spoke with **Dr.Emily Carter**, a registered dietician and expert in geriatric nutrition at the National Institute on Aging, and **Dr. David chen**, a neurologist specializing in cognitive disorders at New York University Langone Health.
**The Link Between Calcium, Magnesium, and Cognitive Health**
**World-today News:** Dr. Carter, can you explain the key takeaways from this Polish study?
**Dr.Emily Carter:** This study is particularly significant because the researchers didn’t solely rely on dietary questionnaires—they directly measured calcium and magnesium levels in participants’ blood. This provides more reliable data than relying on self-reported dietary habits. The findings clearly show that lower levels of both calcium and magnesium correlate with poorer cognitive performance in individuals over 60.
**World-Today News:** Dr. Chen, how does this connect with the broader understanding of cognitive decline?
**Dr.David Chen:** We certainly know that aging, cardiovascular disease, and chronic inflammation all contribute to cognitive decline.What this study suggests is that inadequate calcium and magnesium levels might be another key factor – essentially another piece of the puzzle. Maintaining optimal levels of these minerals could perhaps slow down or even prevent some degree of cognitive decline.
**Understanding the Role of Calcium**
**World-Today News:** Dr.Carter, why is calcium so crucial for brain function?
**Dr.Emily Carter:** Calcium plays a vital role in many neurological processes, including nerve impulse transmission and synaptic plasticity – the brain’s ability to change and adapt.
“Levels of calcium in brain cells are incredibly important for learning and memory.”
When these processes are compromised, it can lead to cognitive impairment.
**world-Today News:** What dietary recommendations can you provide based on these findings?
**Dr. Emily Carter:** Encourage readers to incorporate calcium-rich foods like dairy products, leafy green vegetables, and fortified foods into thier daily meals. If dietary changes aren’t sufficient, talk to your doctor about potential calcium supplements.
**Focus on Lifestyle and Prevention**
**World-today News:** Dr. Chen, what are the broader implications of this research for preventing cognitive decline?
**Dr. David Chen:** This study emphasizes the importance of a proactive approach to brain health.
“Just like we prioritize heart health and bone health, we need to include brain health in our overall well-being plan.”
Staying mentally active, engaging in regular physical exercise, managing chronic conditions, and consuming a balanced diet rich in calcium and magnesium are all crucial steps we can take.
**A call to Action for Readers**
**World-Today News:** What advice would you give to our readers who are concerned about cognitive decline?
**Dr. David chen:** Don’t wait until cognitive issues arise. Talk to your doctor about your concerns and discuss strategies for maintaining brain health. Be proactive about your nutrition, exercise, and overall well-being. Remember, while aging is unavoidable, cognitive decline isn’t.
