What is the Origin of Neurovascular Health?

This term is a clinical synthesis of concepts from vascular biology and neuroscience, recognizing the brain's obligate dependence on a highly controlled and efficient blood supply. The term highlights the neurovascular unit, which includes endothelial cells, pericytes, astrocytes, and neurons, as a single, functionally integrated entity. Its relevance in hormonal health is due to the profound vascular effects of sex steroids, thyroid hormones, and insulin signaling.

What is the Mechanism of Neurovascular Health?

Maintenance of neurovascular health relies on endothelial cells maintaining a non-thrombogenic surface and tightly regulating permeability at the blood-brain barrier interface. Hormones like estrogen can enhance nitric oxide production, promoting beneficial vasodilation and improved cerebral blood flow dynamics. Astrocytes play a key role in coupling local neuronal activity to blood supply, ensuring energy delivery precisely where and when it is needed for optimal brain function.

Neurovascular Health

Meaning

Neurovascular Health refers to the optimal structural integrity and functional efficiency of the intricate network of blood vessels, the blood-brain barrier, and associated glial cells that supply the central nervous system with essential oxygen and metabolic substrates while clearing waste. Robust neurovascular health is paramount for sustained cognitive performance and is tightly regulated by hormonal and metabolic signals. Dysfunction in this integrated system is a precursor to many neurodegenerative and cognitive disorders.
