Research suggests that early life stress may have an impact on the development of the hippocampus, potentially affecting myelination in this area of the brain. Some studies have investigated the role of oligodendrocyte lineage cells and lipid metabolism in this process, as well as the effects of perinatal stress on hippocampal volume in young adults. The relationship between early life stress, brain development, and potential interventions such as exercise is being explored in various studies.
