What is the Origin of Cortical Function Preservation?

This concept is rooted in the neurobiology of aging and the clinical study of neurodegenerative diseases, where the progressive loss of cortical function is a primary clinical feature. The emphasis on "preservation" highlights a preventative and proactive clinical stance rather than merely reactive treatment. Within endocrinology, it recognizes the critical protective role of hormones like estrogen and testosterone on cortical neuronal viability and synaptic function.

What is the Mechanism of Cortical Function Preservation?

Preservation relies on several interconnected pathways, including the maintenance of robust vascular health to ensure consistent delivery of oxygen and nutrients to cortical neurons. Hormones act as key modulators by promoting neurogenesis, enhancing synaptic plasticity, and reducing the accumulation of pathological protein aggregates. Furthermore, the sustained regulation of growth factors, such as Brain-Derived Neurotrophic Factor (BDNF), is essential for supporting the survival and function of cortical neuronal networks.

Cortical Function Preservation

Meaning

Cortical Function Preservation refers to the clinical and biological goal of maintaining the structural integrity and high-level processing capabilities of the cerebral cortex, the brain region responsible for complex functions like language, memory, and executive control, against age-related and metabolic decline. This preservation is crucial for sustaining cognitive independence and quality of life throughout the lifespan. Strategies focus on mitigating neuroinflammation, optimizing cerebral perfusion, and supporting neuronal health to maintain cortical thickness and connectivity.
