Cognitive resilience in ageing: determinants and interventions.

Area of Science:

• Gerontology and Neuroscience
• Aging Research
• Cognitive Health

Background:

• Preserving cognitive abilities in advanced age despite brain pathology is a key research goal.
• Advances in biomarkers allow cognitive function to be assessed alongside markers of brain injury and diseases like Alzheimer's.
• Understanding cognitive resilience and its social determinants across the lifespan is essential for developing effective strategies.

Purpose of the Study:

• To explore factors contributing to cognitive resilience in aging.
• To inform strategies for enhancing cognitive resilience at individual and population levels.
• To address the translation of cognitive resilience research to low- and middle-income countries.

Main Methods:

• Utilizing advances in laboratory and imaging biomarkers to assess cognitive function in the context of brain pathology.
• Analyzing characteristics of individuals exhibiting cognitive resilience.
• Reviewing evidence of interventions to improve cognitive functioning.

Main Results:

• Biomarker data supports the effectiveness of some interventions in high-income countries.
• Knowledge on cognitive resilience characteristics and social determinants is growing.
• There is a recognized need for global expansion of this research.

Conclusions:

• Cognitive resilience is a critical area of aging research.
• Interventions show promise, but require further validation and broader application.
• Translating cognitive resilience research to low- and middle-income countries presents challenges and opportunities for addressing the growing dementia burden.
