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 Levels: A Silent Threat to Cognitive Health?
**New research links low calcium levels to cognitive decline in older adults, highlighting the importance of dietary choices for brain health.**
A recent study published in the journal “Nutrients”, conducted by the Medical University of Lodz in Poland, has shed light on a crucial connection between calcium levels and cognitive function in individuals over 60. The study, which involved blood tests and cognitive assessments of over 1,200 participants, revealed a significant correlation between low blood calcium and poorer cognitive performance.
To discuss the implications of these findings and explore strategies for maintaining cognitive health, we spoke with Dr. Emily parker, a leading registered dietitian and Geriatric Nutrition Specialist at the University of california, San Francisco. We also sought the insights of Dr. Michael davis, a neurologist and aging expert at Johns Hopkins Medicine.
**Understanding the Calcium-Cognition Connection**:
**Interviewer**: Dr. Parker, can you elaborate on the study’s findings and explain why calcium is so important for cognitive function?
**Dr. Parker**: this study adds to a growing body of evidence suggesting that calcium plays a vital role in maintaining brain health as we age. Calcium is essential for nerve cell communication and overall brain function.
**Dr. Davis**: While we traditionally associate calcium with strong bones, its role in the brain is equally crucial. Adequate calcium levels help regulate neurotransmitter release, which is essential for proper communication between brain cells. Deficiencies can lead to impaired cognitive function and perhaps accelerate cognitive decline.
**Beyond Calcium: The Role of Magnesium and Diet**:
**Interviewer**: the study also highlighted the importance of magnesium. can you discuss its role and the synergistic relationship between these two minerals?
**Dr. Parker**: Magnesium is a crucial cofactor in over 300 enzymatic reactions in the body, manny of which are involved in nerve function and brain health. Both calcium and magnesium work synergistically to support healthy brain function, highlighting the need for a balanced intake of both minerals.
**Dr. Davis**: This study reinforces the importance of a holistic approach to cognitive health. It’s not just about calcium; it’s about getting the right balance of essential nutrients through a diverse and balanced diet.
**Practical Steps for Protecting Cognitive Health**:
**Interviewer**: What practical steps can older adults take to ensure adequate calcium and magnesium intake?
**Dr. Parker**: Focus on calcium-rich foods like dairy products, leafy green vegetables, fortified cereals, and almonds.For magnesium, incorporate foods like spinach, black beans, almonds, and avocados into your diet.
**Interviewer**: Besides diet, are there other lifestyle factors that can contribute to cognitive health?
**Dr. Davis**: Regular physical activity, mental stimulation, quality sleep, and stress management are all vital for brain health.
**Looking ahead**:
**Interviewer**: Where does this research leave us in terms of future directions?
**Dr. Parker**: This research highlights the need for further studies to explore the long-term impact of calcium and magnesium supplementation on cognitive function.
**Dr. Davis**: Understanding the precise mechanisms by which these minerals influence brain health can pave the way for targeted interventions and personalized approaches to cognitive health.
**Key Takeaways**:
low calcium levels can contribute to cognitive decline, emphasizing the importance of a calcium-rich diet forbrain health. Magnesium also plays a crucial role alongside calcium in maintaining cognitive function. A balanced diet, enriched with calcium- and magnesium-rich foods, along with other healthy lifestyle choices, can contribute considerably to preserving cognitive health as we age.
