The therapeutic objective of re-establishing and enhancing the brain’s inherent capacity to reorganize synaptic connections, create new neurons (neurogenesis), and adapt its functional architecture in response to experience, learning, or injury. This restoration is intimately linked to hormonal health, as neurosteroids and trophic factors like Brain-Derived Neurotrophic Factor (BDNF) are crucial modulators of neuronal growth and connectivity. Declining plasticity contributes significantly to cognitive aging.
Origin
This concept synthesizes decades of research from neurobiology, developmental psychology, and endocrinology, moving from the foundational understanding of brain malleability to a clinical goal for anti-aging and cognitive health. It represents the application of basic science to maintain lifelong cognitive reserve. The term reflects an active intervention strategy against age-related cognitive decline.
Mechanism
Restoration is facilitated by optimizing hormonal signaling, such as thyroid hormone and estrogen, which directly influence gene expression related to synaptic structure and function. Strategies often include targeted interventions that promote BDNF release, which is a potent stimulator of neurogenesis in the hippocampus and other brain regions. The mechanism enhances communication efficiency across neuronal circuits, improving memory and executive function.
