A comprehensive clinical goal focused on maximizing the duration of life during which an individual maintains high-level cognitive function, emotional resilience, and neurological vitality. This objective goes beyond merely preventing disease; it actively seeks to preserve and enhance cognitive reserve and neuroplasticity deep into old age. It represents the successful application of neuroprotective and neuromodulatory strategies over time. The ultimate measure is sustained functional independence and mental acuity.
Origin
This term is a convergence of the fields of gerontology, neuroscience, and longevity medicine, applying the concept of “healthspan” (the period of life spent in good health) specifically to the central nervous system. The idea of “Extension” emphasizes an active, preventative, and restorative clinical strategy, moving beyond traditional palliative care models.
Mechanism
The mechanism involves multifaceted strategies targeting the hallmarks of brain aging, including reducing chronic neuroinflammation and mitigating the accumulation of pathological protein aggregates. Key interventions often focus on supporting synaptic integrity, promoting neurogenesis in regions like the hippocampus, and optimizing the hormonal environment that governs brain function. These actions collectively work to maintain the structural and functional capacity of neural networks.
