Summary
Arterial hypertension (AH) is a significant risk factor for cognitive decline and dementia. While AH requires treatment to normal blood pressure, overly aggressive lowering is not advised due to potential J-curve effects.
Area of Science:
- Neurology
- Cardiology
- Gerontology
Background:
- Arterial hypertension (AH) is a known risk factor for vascular cognitive impairment.
- Its role in Alzheimer's disease is also being investigated.
- The relationship between AH and dementia remains incompletely understood.
Purpose of the Study:
- To review major prospective clinical trials examining the link between arterial hypertension and cognitive impairment.
- To summarize current understanding of AH's impact on dementia.
- To provide therapeutic guidance for managing AH in the context of cognitive health.
Main Methods:
- Review of prospective clinical trials.
- Analysis of existing literature on hypertension and cognitive decline.
- Synthesis of findings regarding treatment strategies.
Main Results:
- Inconsistent findings exist regarding the precise interrelations between AH and dementia.
- Current evidence does not support the superiority of any specific antihypertensive regimen for dementia prevention.
- A simple rule for AH therapy is to treat until normal blood pressure is achieved.
Conclusions:
- The link between arterial hypertension and dementia requires further investigation.
- Overly aggressive blood pressure reduction should be avoided pending further evidence on the J-curve hypothesis.
- Effective management of AH is crucial, but specific regimens for dementia prevention are not yet established.
