Early-life stress leaves lasting 'scars' in brain cells, study finds

Early-life trauma survivors experience increased vulnerability to anxiety and depression throughout adulthood due to lasting neurobiological changes.

Science has long known that childhood trauma casts a long shadow into adult life; now researchers have found where that shadow lives inside the brain itself. Early-life stress measurably depletes myelin — the protective sheath around nerve fibers — in the gray matter regions that govern emotion and fear, leaving the brain's regulatory infrastructure physically compromised for decades. This is not a story about fragility of character, but about the biology of survival: a nervous system shaped by adversity that continues to bear the structural cost of what it once endured.
