Cognitive Resilience

Meaning

Cognitive resilience is the capacity of the brain and its functional networks to maintain or rapidly recover cognitive performance despite exposure to physiological or psychological challenges. This includes enduring age-related changes, hormonal fluctuations, or acute stressors without significant decline in executive function, memory, or processing speed. High cognitive resilience reflects a robust neurological system capable of adaptive compensation against internal and external perturbations. Clinically, it is a critical marker for maintaining independence and quality of life across the lifespan.
