Engaging in novel cognitive experiences and environmental enrichment stimulates neuronal plasticity mechanisms (such as neurogenesis and synaptogenesis) and promotes cognitive integrity, thereby ameliorating cognitive aging.
To maintain cognitive health as you age, prioritize learning new skills and seeking novel experiences. The paper suggests that 'environmental enrichment'—such as learning a new language, instrument, or complex hobby—triggers the brain's plasticity mechanisms (like neurogenesis and synaptogenesis). This active engagement is more effective than passive activities because the novelty itself stimulates the necessary neural adaptations.
We hypothesize that successful cognitive aging requires interactions between neuronal and cognitive plasticity, with the interactions being stimulated by environmental demands and supported by factors which enhance brain integrity. ... We further argue that in the absence of disease, factors that enhance this interactive process can promote both cognitive integrity (preserved cognitive ability) and brain integrity (preserved brain structure) in healthy old age. An important factor is exposure to novel experiences.
Why this rating
The paper is a hypothesis/theory review citing animal models and observational human studies; it proposes testable randomized trials rather than presenting new primary RCT data.
