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, Big Impact: Can This Mineral Really Protect Your Brain?
new research has linked **low calcium levels to cognitive decline** in older adults.This study, published in the journal ”Nutrients”, adds another layer to the ongoing discussion about diet and its crucial role in maintaining brain health as we age.
Today,we’re joined by **Dr. Emily Carter**, a registered dietician and expert in geriatric nutrition at Johns Hopkins University, and **Dr.Robert Jones**, a neurologist and cognitive health specialist at the University of California, San Francisco. They’ll unpack the findings of this groundbreaking study, explain the science behind calcium and its impact on the brain, and offer practical advice on how to ensure optimal calcium intake for cognitive longevity.
**Calcium: A Crucial Link to Cognitive Function?**
**World Today News:** Dr. Carter, can you walk us through the key takeaways from this study?
**Dr. Emily Carter:** This Polish study is important because it directly measured both calcium and magnesium levels in blood samples, avoiding reliance on potentially inaccurate dietary questionnaires. The findings clearly show a strong connection between low blood calcium levels and poorer cognitive performance in individuals over 60.
**World Today News:** Dr. Jones, what is the biological mechanism behind this link between calcium and cognitive function?
**Dr. Robert Jones:** Calcium plays a vital role in nerve cell communication. It helps transmit signals between neurons, which is essential for functions like memory, learning, and overall cognitive processing.
**”When calcium levels are low, these communication pathways can become disrupted, leading to cognitive decline.” – Dr. Robert Jones**
**World Today News:** Are there other factors besides age contributing to calcium deficiency and cognitive decline?
**Dr. Emily Carter:** Absolutely. The study also highlighted the role of cardiovascular disease and chronic inflammation, both of which can increase the risk of cognitive deficiency.
**Practical Strategies for maintaining Cognitive Health**
**World Today News:** Dr. Carter, what are some practical steps individuals can take to ensure adequate calcium intake and protect their cognitive health?
**Dr. Emily Carter:**
* **Dietary Sources:** Encouraging consumption of calcium-rich foods like dairy products, leafy greens, fortified foods, and certain fish.
* **Supplementation:** In cases of confirmed deficiency, calcium supplements might be recommended under a doctorS guidance.
* **Lifestyle Factors:** Addressing underlying health conditions like heart disease and managing inflammation through diet and exercise.
**World Today News:** What are your predictions for the future of research in this field?
**Dr. Robert Jones:** this study opens up exciting avenues for further examination. We need to delve deeper into the specific mechanisms by which calcium influences brain function at a molecular level.
**Maintaining Cognitive Vitality**
This research provides another powerful reminder that our dietary choices have a profound impact on our brain health. By optimizing calcium intake through a balanced diet and addressing overall health concerns,we can empower ourselves to maintain cognitive vitality and enjoy a longer,sharper life.
