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: Could This Mineral Be Key to Preventing Cognitive Decline?
**New research suggests a link between low blood calcium levels adn cognitive decline in individuals over 60, raising important questions about the role of nutrition in preserving brain health.** While previous studies have focused on magnesiumS importance for cognitive function, this groundbreaking study from the Medical University of Lodz delves deeper, directly measuring both calcium and magnesium levels in participants.
To unpack the implications of these findings, we spoke with Dr. Emily Carter, a leading neurologist and expert in age-related cognitive changes, and Dr. David Ramirez, a registered dietitian specializing in geriatric nutrition.
### Understanding the Calcium-cognition Connection
**World Today News:** Dr. Carter, can you explain the link between calcium and cognitive function as discovered in this study?
**Dr. Carter:** This research adds a crucial piece to the puzzle of cognitive decline. We know that calcium is essential for many bodily functions, including nerve transmission. This study suggests that low calcium levels may disrupt these processes in the brain, contributing to cognitive impairment. While more research is needed, the findings are compelling and warrant further investigation.
**World Today News:** Dr. Ramirez, how can people ensure they’re getting enough calcium through their diet?
**Dr.Ramirez:** Dairy products are a well-known source of calcium,but it’s also found in leafy green vegetables like kale and spinach,fortified foods like plant-based milks,and even certain types of fish like sardines and salmon. It’s critically important to diversify your diet and include a range of calcium-rich foods.
### The Magnesium Factor
**World Today news:** dr. Ramirez, the study also noted the importance of magnesium.How does it play a role in cognitive health?
**Dr. Ramirez:** magnesium is involved in over 300 biochemical reactions in the body, including those that impact neuron function and nerve signaling. Studies have shown that adequate magnesium intake may protect against cognitive decline and even improve memory.
**World Today News:** Is there synergy between calcium and magnesium for cognitive health?
**Dr. Carter:** Absolutely. These minerals work together in numerous ways. For example, both are vital for neurotransmitter release and the regulation of nerve impulses. Ensuring adequacy of both nutrients is likely crucial for optimal brain function.
### Beyond Diet: Holistic Approaches to Brain Health
**World Today News:** Dr. Carter, are there other lifestyle factors that contribute to cognitive decline beyond nutrition?
**Dr. Carter:**
Absolutely. Aging,cardiovascular disease,chronic inflammation,and lack of physical activity can all increase the risk of cognitive decline. It’s vital to adopt a holistic approach to brain health,incorporating regular exercise,stress management techniques,and mental stimulation.
**World Today News:** Dr. Ramirez, what are your recommendations for individuals concerned about maintaining cognitive function as they age?
**Dr. Ramirez:**
“Prioritize a balanced diet rich in fruits, vegetables, lean protein, and whole grains. Focus on calcium and magnesium-rich foods. Consult with your doctor or a registered dietitian to determine whether supplementation might potentially be beneficial.”
**”Don’t underestimate the power of lifestyle factors. Engage in regular physical activity, stay socially connected, challenge your mind with puzzles and learning, and manage stress effectively.”**
### Looking Ahead: A Future of Focused Nutrition
**World Today News:** What exciting research avenues are on the horizon in the field of nutrition and cognitive health?
**Dr. Carter:** We’re entering an exciting era where personalized nutrition is becoming increasingly possible.Research is ongoing to identify specific dietary interventions that target individual genetic and metabolic profiles to optimize cognitive function and potentially slow down cognitive decline.
**The Key takeaway:** This groundbreaking study highlights the critical role of calcium in maintaining cognitive health, emphasizing the need for a proactive approach to nutrition.
**What can you do?** Prioritize calcium-rich foods in your diet, talk to your healthcare provider about potential deficiencies, and embrace a holistic approach to brain health.
