What is the Origin of Preserved Cognitive Reserve?

This concept originated in neuropsychology and geriatric medicine to explain the discrepancy between brain pathology observed post-mortem and the actual cognitive function experienced during life. 'Preserved' highlights the successful maintenance of this functional capacity. In the hormonal domain, it is linked to the neuroprotective effects of balanced sex steroids and thyroid hormones.

What is the Mechanism of Preserved Cognitive Reserve?

The mechanism involves promoting neuroplasticity, synaptogenesis, and the reduction of chronic neuroinflammation, all of which are modulated by the endocrine system. Optimized levels of hormones, such as estrogen, testosterone, and DHEA, support the structural integrity and functional efficiency of neural networks, allowing the brain to better compensate for subtle damage. Lifestyle interventions and targeted hormonal support are employed to bolster this reserve, ensuring sustained cognitive vitality.

Preserved Cognitive Reserve

Meaning

Preserved Cognitive Reserve denotes the sustained, measurable resilience of the brain’s capacity to function effectively and maintain high-level executive control despite the presence of age-related or pathological changes in neural structure. This clinical state is not merely the absence of cognitive decline but the active maintenance of neural efficiency and adaptability. It is a key biomarker of successful brain aging and is strongly influenced by optimized hormonal and metabolic health.
