Childhood trauma impacts brain biology
A recent study indicates that trauma experienced by children during early developmental stages leaves a lasting "physical scar" in their brains and affects their future responses to stress. It has been shown that early stress enhances the activity of brain cells responsible for processing pressure and increases the brain's sensitivity to difficulties, which later exposes the child to higher risks of anxiety, depression, and mood disorders. Molecular changes linked to stress, especially the modification of DNA structure via the enzyme SETD7, contribute to the formation of molecular memory that recalls past conflicts. This reduces the brain's resilience and raises the likelihood of developing psychological problems later on. The study suggests that early interventions, such as care and social support, can help protect the brain from these changes and provide long-term functional resilience.
