Physical activity reshapes neural connectivity and makes the brain more resilient after childhood trauma

New research indicates that the long-term neurological impact of childhood trauma is not permanently etched onto the brain. An analysis of brain communication patterns in a group of individuals who have experienced childhood adversity shows that lifetime physical activity can reshape neural connectivity, thereby strengthening the brain's internal communication and optimizing its response to stress. The findings from the study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, move beyond the idea of a permanently traumatized brain, highlighting physical activity as a modifiable lifestyle factor associated with neurobiological adaptation.
