The detrimental lifelong impacts of early life adversity on brain

Motivation: Early life adversities (ELAs) have long-lasting detrimental impacts on physical and mental health across life course, insisting the experience of ELAs disturb healthy neuronal brain development. Goal(s): Our goal is to investigate on the underlying mechanism of the long-lasting ELAs impacts on brain. Approach: We examined the brains of non-human primate experienced with the ELAs of social separation from conspecific caregivers from our non-human primate MRI database in retrospective manner. Results: Non-human primate brain with caregiver adversities (i.e. ELAs) exerts underdevelopment of multiple brain regions in both cortical and subcortical regions. Impact: Our study demonstrates the lifelong detrimental impact of the early life adversities on brains, proving that the early life experiences, especially social ones, are the important factor for structuring brain during development.
