The Relationship of Blood Pressure on Cognitive Function in Hypertension Patients

Abstract

WHO explains that hypertension continues to increase every year, it is estimated that in 2025 1.5 billion people with hypertension and 9.4 million people die every year due to hypertension and its complications. The prevalence of hypertension in Indonesia based on the results of Riskesdas is 34.1%. This figure is higher than the previous year which touched a prevalence rate of 25.8%. Patients with hypertension cause large blood vessels to constrict, so that the flow of blood entering through the blood vessels will decrease. If the constriction is too large there will be blockage, resulting in a decrease in oxygen levels carried by the blood to the brain. Decreased oxygen levels in the brain will cause disturbances. Cognitive function. Objective: This study aims to determine the relationship between blood pressure and cognitive function in patients with hypertension. Method: This type of research was quantitative with a cross sectional approach. The sampling technique used was random sampling (as many as 40 respondents) in the Tegaltandan and Jomblangan. The data analysis technique in this study used Kendall Tau. Results: The results revealed p value 0.000 < = 0.05 and the correlation coefficient value was −0.653**. Conclusion: There was a relationship between blood pressure and cognitive function in hypertensive patients in the Tegaltandan and Jomblangan with a strong negative relationship. Suggestion: Hypertensive patients are expected to routinely control blood pressure to reduce problems that can cause cognitive dysfunction.
