The Relationship Between the Glomerular Filtration Rate and Cognitive Function in Diabetes Mellitus Patients

Introduction

Diabetes mellitus (DM) is a chronic disease that affects the way the body regulates blood sugar. It is a leading cause of morbidity and mortality worldwide, and its complications can affect various organs of the body, including the kidneys. Chronic kidney disease (PGK) is one of the complications of DM, characterized by a decrease in kidney function, which is assessed through the Glomerular Filtration Rate (GFR) level. Studies have shown that the prevalence of dementia and mild cognitive disorders (Mild Cognitive Impairment/MCI) is higher in patients with DM than the general population. However, not many studies have examined the relationship between GFR values and cognitive function disorders in DM patients.

Background

Diabetes mellitus is a complex disease that affects the body's ability to regulate blood sugar levels. It is caused by a combination of genetic and environmental factors, including obesity, physical inactivity, and a diet high in sugar and refined carbohydrates. The disease is characterized by high blood sugar levels, which can lead to a range of complications, including kidney damage, nerve damage, and vision loss.

Chronic kidney disease (PGK) is a common complication of DM, affecting up to 40% of patients with the disease. It is characterized by a gradual decline in kidney function, which can lead to a range of symptoms, including fatigue, swelling, and shortness of breath. The GFR is a measure of kidney function, and a decrease in GFR is a hallmark of PGK.

Studies have shown that the prevalence of dementia and mild cognitive disorders (MCI) is higher in patients with DM than the general population. However, not many studies have examined the relationship between GFR values and cognitive function disorders in DM patients.

Methodology

This study is a cross-sectional study conducted in the endocrinological polyclinic of the Department of Internal Medicine Hospital H Adam Malik Medan by involving 35 DM patients. The GFR value is measured using the MDRD (Modification of Diet In Renal Disease) method, while cognitive functions are assessed using MMSE (Mini Mental Stage Examination) and CDR (Clinical Dementia Rating).

Results

The results showed that there was a significant relationship between GFR values and cognitive function disorders in DM patients. In measurements using MMSE, which is tailored to the age and level of education, 28 patients have normal cognitive functions and 7 patients experience MCI. When using CDR, 4 patients experience MCI and 31 patients have normal cognitive functions. The T-Independent test shows a significant relationship between the GFR value and the cognitive function disorder, both using MMSE (P = 0.036) and CDR (P = 0.004).

Discussion

This study provides additional evidence about the close relationship between kidney function and cognitive health in DM patients. Although this study has a limited number of samples, significant results indicate that decreased kidney function can be associated with an increased risk of cognitive disorders in DM patients. This is probably caused by several factors:

Decreased oxygen supply to the brain: Decreased kidney function can cause a decrease in blood flow to the brain, which results in a reduction in the supply of oxygen and nutrients needed for optimal cognitive function.
Toxins and metabolites:** Decreased kidney function resulting in a buildup of toxins and metabolites harmful in the blood, which can affect cognitive function and even cause brain damage.
Chronic inflammation:** PGK is often accompanied by chronic inflammation, which can affect brain function and increase the risk of cognitive disorders.

Implications for Health

These findings have important implications for the health of DM patients. It is essential for doctors to monitor kidney function regularly in DM patients and do early intervention in the event of a decrease in GFR. Control of blood sugar, blood pressure, and good cholesterol levels is also important to prevent kidney damage and maintain cognitive health.

Recommendation

Further research is needed with a larger number of samples and a longer period of time to confirm these findings and identify other factors that may affect the relationship between GFR values and cognitive functions in DM patients. In addition, research on intervention strategies to prevent or delay cognitive disorders in DM patients with a decrease in GFR is also very necessary.

Conclusion

This study shows a significant relationship between GFR values and cognitive function disorders in DM patients. This finding emphasizes the importance of routine kidney function monitoring in DM patients and early intervention to maintain cognitive health and prevent long-term complications.

Future Directions

Future studies should aim to:

Confirm the findings: Conduct larger-scale studies to confirm the relationship between GFR values and cognitive function disorders in DM patients.
Identify other factors: Investigate other factors that may affect the relationship between GFR values and cognitive functions in DM patients.
Develop intervention strategies: Develop and test intervention strategies to prevent or delay cognitive disorders in DM patients with a decrease in GFR.

Limitations

This study has several limitations, including:

Small sample size: The study had a small sample size, which may limit the generalizability of the findings.
Cross-sectional design: The study had a cross-sectional design, which may not allow for the examination of the temporal relationship between GFR values and cognitive function disorders.

Conclusion

In conclusion, this study provides additional evidence about the close relationship between kidney function and cognitive health in DM patients. The findings emphasize the importance of routine kidney function monitoring in DM patients and early intervention to maintain cognitive health and prevent long-term complications. Future studies should aim to confirm the findings, identify other factors that may affect the relationship between GFR values and cognitive functions in DM patients, and develop intervention strategies to prevent or delay cognitive disorders in DM patients with a decrease in GFR.
Frequently Asked Questions (FAQs) About the Relationship Between Glomerular Filtration Rate and Cognitive Function in Diabetes Mellitus Patients
