Insights
Hypertension significantly drives cerebral small vessel disease, leading to cognitive impairment. This review clarifies the link between high blood pressure and brain changes, discussing potential treatments.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Gerontology
Background:
- Hypertension is a major risk factor for cognitive impairment linked to cerebral small vessel disease (CSVD).
- The exact causal link between hypertension and CSVD remains incompletely understood.
- CSVD is the most common cerebrovascular disease, often leading to stroke and dementia.
Purpose of the Study:
- To review the pathogenesis of hypertension-induced CSVD.
- To elucidate the impact of hypertension on brain structure, function, and cognitive decline.
- To discuss therapeutic strategies for CSVD and associated cognitive impairment.
Main Methods:
- Literature review focusing on hypertension, CSVD, and cognitive impairment.
- Analysis of mechanisms linking hypertension to cerebrovascular changes.
- Synthesis of current understanding of pathogenesis and treatment.
Main Results:
- Hypertension is identified as the primary driver of CSVD.
- Hypertension-induced vascular changes lead to lacunar infarction, leukoaraiosis, white matter lesions, and intracerebral hemorrhage.
- The brain is confirmed as a target organ of hypertension, with significant cognitive decline observed.
Conclusions:
- Hypertension critically contributes to CSVD pathogenesis and subsequent cognitive decline.
- Understanding these mechanisms is crucial for developing effective treatments.
- Further research into therapeutic interventions for hypertension-related brain damage is warranted.
Abstract:
Hypertension is a primary risk factor for the progression of cognitive impairment caused by cerebral small vessel disease, the most common cerebrovascular disease. However, the causal relationship between hypertension and cerebral small vessel disease remains unclear. Hypertension has substantial negative impacts on brain health and is recognized as a risk factor for cerebrovascular disease. Chronic hypertension and lifestyle factors are associated with risks for stroke and dementia, and cerebral small vessel disease can cause dementia and stroke. Hypertension is the main driver of cerebral small vessel disease, which changes the structure and function of cerebral vessels via various mechanisms and leads to lacunar infarction, leukoaraiosis, white matter lesions, and intracerebral hemorrhage, ultimately resulting in cognitive decline and demonstrating that the brain is the target organ of hypertension. This review updates our understanding of the pathogenesis of hypertension-induced cerebral small vessel disease and the resulting changes in brain structure and function and declines in cognitive ability. We also discuss drugs to treat cerebral small vessel disease and cognitive impairment.
