Improving Cerebrovascular Function to Increase Neuronal Recovery in Neurodegeneration Associated to Cardiovascular...

Area of Science:

• Neuroscience
• Cardiology
• Gerontology

Background:

• Cardiovascular disease (CVD) and its risk factors are linked to increased cognitive impairment (CI) and dementia.
• Impaired cardiovascular function in CVD can disrupt cerebral blood flow (CBF), affecting brain oxygen and nutrient supply.
• Cerebral hypoperfusion and cerebrovascular dysfunction in conditions like hypertension and heart failure are associated with neurodegeneration.

Purpose of the Study:

• To review the mechanisms linking cerebrovascular dysfunction and CBF deficits to neurodegeneration.
• To discuss vascular targets that may attenuate neurodegeneration or CI associated with CVD.

Main Methods:

• Literature review of studies investigating the relationship between CVD, cerebrovascular function, and neurodegeneration.
• Analysis of evidence for vascular targets in mitigating CVD-related cognitive decline.

Main Results:

• CVD impairs CBF regulation, leading to reduced oxygen and nutrient supply critical for neuronal function.
• Hypertension, heart failure, and stroke are associated with cerebral hypoperfusion and impaired cerebrovascular function, contributing to neurodegeneration.
• Certain vascular targets have shown promise in improving cerebrovascular function and CBF, potentially reducing neurodegeneration.

Conclusions:

• Understanding the mechanisms linking cerebrovascular dysfunction to neurodegeneration is crucial for developing effective treatments.
• Improving cerebrovascular function and addressing CBF deficits represent a promising therapeutic strategy for CVD-associated neurodegeneration and CI.
