To reduce the scale and impact of dementia, we need to raise awareness among the population and stakeholders in low- and middle-income countries by providing more evidence on its burden, which will contribute in policy and behavior changes.


Maëlenn is committed to developing new aging and brain health research by first revising and validating a culture- and education-fair one-stage diagnostic assessment in sub-Saharan Africa. This is a critical step in the implementation of large population-based surveys to quantify and understand the burden of dementia in this region.


As an Atlantic fellow, I have benefited from a new insight into multidisciplinary brain health research both through seminars and stimulating discussions with my fellow fellows. Together with mentorship, this has reinforced my will to contribute to a global effort towards equity in brain health.


Data on the burden of dementia in low- and middle-income countries is still limited, especially in sub-Saharan Africa where awareness is low.
