 My research has mainly focused on the epidemiology of aging, with the aim of understanding how environmental factors, in particular diet, influences the aetiology of brain diseases and conditions in aging, such as dementia, cognitive decline or stroke. Since environmental factors have a pleiotropic role in health, a broader perspective of my research has recently focused on environmental strategies to maintain overall health in aging. Specifically, I have contributed to demonstrate the impact of a healthier diet in midlife (eg., a Mediterranean diet) for healthy aging. There is indeed increasing evidence that a number of age-related diseases originate in midlife and even in earlier periods of life. For example, it is now recognized that lesions associated with age-related brain diseases accumulate silently over decades before brain diseases in the late-life. At the same time, brain plasticity, which provides more numerous neurons and connections – globally referred to as “brain reserve” – to cope with lesions and maintain optimal cognitive performances with aging, start developing in the first decades of life. While it has become more and more evident that future brain aging research should move on early prevention, the optimal strategy, including the most critical window of opportunity for prevention, remains to be elucidated. To inform early mechanisms underlying the relation of the environment and brain health, I am currently working on extending my research interests to the investigation of environmental factors and brain structure of young adults in a large ongoing cohort of French students. A better understanding on how the environment shapes brain structural plasticity in early adult life will eventually help designing future prevention strategies.
