Gaël Chételat | Brain Health and Ageing: From Risk to Resilience | Milan Longevity Summit 2026

*Optimizing Brain Aging: Reducing Risk, Strengthening Resilience* Can we build a more resilient brain before disease begins? In this session from *Brain Health and Ageing: From Risk to Resilience* at the *Milan Longevity Summit 2026*, *Dr. Gaël Chételat* explores why some individuals remain cognitively healthy despite age-related brain changes, while others experience accelerated decline. Her research focuses on brain resilience—the capacity to maintain cognitive function despite the presence of ageing or pathology. Through advanced neuroimaging and longitudinal studies, Dr. Chételat examines how lifestyle, education, cognitive reserve, and biological factors interact to reduce dementia risk and promote healthy brain ageing. Dr. Gaël Chételat is Research Director at *INSERM* in Caen and one of Europe's leading experts in cognitive neuroscience and Alzheimer's disease. Her pioneering work combines neuroimaging, biomarkers, and cognitive assessment to better understand the mechanisms of resilience and identify strategies that support lifelong brain health. The Milan Longevity Summit brings together global leaders across science, medicine, policy, business, technology and society to rethink the future of health through a *One Health* perspective—recognising that the wellbeing of people, planet and economies is deeply interconnected. *Learn more about the Milan Longevity Summit:* https://www.milanlongevitysummit.org/it/speakers26/gael-chetelat #MilanLongevitySummit #Longevity #OneHealth #GaelChetelat #BrainHealth #BrainResilience #Alzheimers #Neuroscience #HealthyAgeing #Healthspan
