Admittedly, the cases described here are extreme, but they do remind us of the cost of early childhood malnutrition can be devastating.
From the World Bank:
Brain imaging in Bangladesh. Nelson also shared findings from a study using neuroimaging tools (EEG, fNIRS, MRI) to study cognitive development in children 6 and 36 months old exposed to multiple types and levels of early adversities in Dhaka, Bangladesh. For both cohorts, results show reduced cognitive outcomes for those children growing up in the most adverse conditions. Factors such as maternal education, inflammation, and stunting due to chronic malnutrition mediate these poor outcomes. As the figure below shows, these kids’ brain anatomy, metabolism and physiology are all impacted by adversity, particularly stunting.
