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 Blood Calcium Linked to Cognitive Decline: A Conversation with Experts
maintaining cognitive function as we age is a key concern for many individuals. Recent research from the Medical University of Lodz in Poland shed new light on a potential dietary factor: **calcium**. The study, published in the journal *Nutrients*, revealed a notable connection between **low blood calcium levels and poorer cognitive performance in individuals over 60**.
To delve deeper into these findings and explore their implications, we sat down with two leading experts: **Dr. Emily Carter**, a geriatrician specializing in cognitive health, and **Dr. Mark Sullivan**, a registered dietitian and nutrition scientist.
**Understanding the Link Between Calcium and Cognition**
**World Today News:** Dr. Carter, can you explain the main findings of this study and what they mean for older adults?
**Dr. Carter:** This study reinforces the growing understanding of the essential role of nutrition in brain health. The research showed a direct correlation between lower blood calcium levels and poorer performance on cognitive tests. This is significant as it highlights a potentially modifiable risk factor for cognitive decline.
**World Today News:** Dr. Sullivan, beyond calcium, what other dietary factors might play a role in cognitive function?
**Dr. Sullivan:** This study also highlighted the importance of **magnesium.** While we’ve long known about magnesium’s role in various bodily functions,this research strengthens the link between adequate magnesium levels and cognitive performance. Other essential nutrients like **vitamin D, omega-3 fatty acids, and B vitamins** are also crucial for brain health.
**Can Dietary Changes Make a difference?**
**World Today News:** Dr. Sullivan,what practical steps can individuals take to ensure they are getting enough calcium and magnesium?
**Dr. Sullivan:**
Many people can meet their calcium needs through a balanced diet rich in dairy products, leafy greens, fortified foods, and certain types of fish.**Good sources of magnesium include almonds, spinach, black beans, and avocado.**
For those who struggle to meet their needs through diet alone, supplements can be a helpful option, but it’s critically important to consult with a healthcare professional before starting any new supplements.
**World Today News:** Dr. Carter, what are your recommendations for older adults concerned about cognitive decline?
**Dr. Carter:** Maintaining a healthy lifestyle is crucial. This includes engaging in regular physical activity, managing stress, getting adequate sleep, and staying socially connected.
“**A diet rich in fruits, vegetables, whole grains, and lean protein is also essential for overall health, including brain health.**”
**Addressing Potential Deficiencies**
**World Today news:** Dr. Sullivan, how can people determine if they have calcium or magnesium deficiencies?
**Dr. Sullivan:** A simple blood test can measure your levels of these minerals.It’s critically important to note that deficiencies can be subtle and may not always present with obvious symptoms.
**”That’s why regular check-ups with your healthcare provider are essential, especially as we age.”**
**Moving Forward: Research and prevention**
**World Today News:** What are the next steps in terms of research in this area?
**dr. carter:** Further research is needed to fully understand the complex interplay between nutrition, genetics, and lifestyle factors in cognitive decline. We also need to investigate the long-term effects of nutritional interventions on cognitive health.
**Key Takeaways and Call to Action**
The emerging connection between low blood calcium levels and cognitive decline underscores the importance of paying attention to our nutritional needs. Adopting a diet rich in calcium-rich foods and maintaining a healthy lifestyle can potentially contribute to preserving cognitive function as we age.
