Longevity Cognitive Index

Meaning

The Longevity Cognitive Index is a composite metric designed to quantify an individual’s cognitive reserve and functional efficiency, specifically in the context of healthy aging and neuroprotection. This index moves beyond standard memory tests by integrating measures of executive function, processing speed, and attentional control, which are highly predictive of long-term cognitive healthspan. The score serves as a critical clinical benchmark, reflecting the current neurobiological resilience of the brain against age-related and metabolic stressors. Fluctuations in the index are often early indicators of systemic dysregulation, including hormonal decline or subclinical neuroinflammation.
