Effects of Antihypertensive Drugs on Cognitive Function in Elderly Patients with Hypertension: A Review

Area of Science:

• Gerontology
• Cardiology
• Neurology

Background:

• Hypertension is a prevalent comorbidity in elderly individuals, contributing to cardiovascular diseases.
• Hypertension is also linked to cognitive decline and dementia, increasing morbidity and mortality.
• Existing research on blood pressure, variability, and antihypertensive drugs in relation to cognitive impairment shows inconsistent findings.

Purpose of the Study:

• To review preclinical and clinical evidence on the association between blood pressure control, blood pressure variability, antihypertensive drug use, and cognitive function in elderly hypertensive patients.
• To analyze differences in cognitive outcomes among various antihypertensive drug categories.
• To address the need for a comprehensive understanding due to the global burden of hypertension, aging population, and impact of cognitive impairment.

Main Methods:

• Systematic review of preclinical evidence and clinical research.
• Focus on blood pressure control, blood pressure variability, and antihypertensive drug use.
• Comparative analysis of different antihypertensive drug classes regarding cognitive function.

Main Results:

• The relationship between blood pressure and cognitive function is non-linear and age-dependent.
• Intensive blood pressure control is not generally recommended, especially for the oldest-old.
• Increased blood pressure variability and orthostatic hypotension are associated with a higher risk of cognitive decline.

Conclusions:

• Current evidence does not identify a superior antihypertensive drug class for preventing dementia in elderly hypertensive patients.
• Blood pressure management in elderly hypertensive patients requires careful consideration of age, BP variability, and orthostatic hypotension.
• Further research is needed to clarify optimal antihypertensive strategies for cognitive health in this population.
