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 Calcium Consumption Help Ward off Cognitive Decline?
Maintaining sharp cognitive abilities as we age is a top priority for many. Recent research has revealed a potentially crucial link between calcium levels and cognitive function in older adults. While the role of magnesium in cognitive health has been previously investigated, a new study from the Medical University of Lodz in Poland shines a spotlight on calcium’s critical contribution.
Published in the journal “Nutrients,” the study found a strong correlation between low blood calcium levels and poorer cognitive performance in individuals over 60. To gain deeper insights into this connection, we spoke with Dr. Emily Carter, a registered dietitian specializing in geriatric nutrition, and Dr. Michael Thompson, a neuroscientist focusing on the aging brain, about the implications of these findings.
### The Calcium-Cognition Connection
**Dr. Carter:** This study is a valuable addition to our understanding of the multifaceted factors influencing cognitive health.
previous studies have explored magnesium’s role, but this research directly measured both calcium and magnesium levels, offering a more objective picture than relying on dietary questionnaires.
**Dr. thompson:** Absolutely. The findings are intriguing, showing that even individuals with normal magnesium levels but low calcium levels exhibited signs of cognitive decline. This firmly emphasizes the importance of adequate calcium intake for optimal brain function.
### Understanding the Mechanism
**World Today News:** Can you elaborate on how calcium might contribute to cognitive function?
**Dr. Thompson:** Calcium plays a vital role in neuronal interaction. Within the brain, calcium ions act as messengers, facilitating the transmission of signals between nerve cells.
Insufficient calcium can disrupt this signaling process, potentially leading to cognitive impairments. The study also suggests a link between low calcium and depression, highlighting calcium’s broader impact on mental well-being.
**Dr. Carter:** It’s likely not solely a direct impact on neurons. Calcium also contributes to bone health, and we know that osteoporosis is linked to cognitive decline. This study reinforces the idea that overall health, including bone health, is intertwined with brain function.
### Practical Implications for Older Adults
**World Today News:** What recommendations do you have for older adults concerned about cognitive decline?
**Dr. Carter:** Ensure you’re consuming adequate calcium through your diet. Dairy products, leafy green vegetables, and fortified foods are excellent sources.
**Dr.Thompson:** Consult with your doctor to determine if calcium supplementation might be beneficial, especially if you have a history of low calcium levels or other risk factors for cognitive decline.
### Looking Ahead: Future Research
**World Today News:** What are some potential avenues for future research?
**Dr. Thompson:** Future studies could investigate the optimal dosage of calcium for maintaining cognitive function and explore the potential synergistic effects of calcium and magnesium supplementation.
**Dr. Carter:** It would also be valuable to examine the long-term impact of calcium intake on cognitive function in diverse populations.
**Key Takeaways:**
This study underscores the critical role of calcium in maintaining cognitive health as we age. Adequate calcium intake, through diet and/or supplementation, may help ward off cognitive decline and promote mental well-being.
