How childhood trauma affects the brain?

The brain is being shaped and has experiences shaping how we think, feel, perceive, and behave from birth. An environment that lacks safety or responsiveness can cause attachment issues, emotional difficulties and also impacts the brain. Research has shown that experiencing trauma in childhood increases the risk of numerous mental health issues, including developing depression, anxiety, struggles with substance abuse, and more.

Trauma is any event that a person perceives as dangerous or threatening to their safety or the safety of a loved one. Childhood trauma may include witnessing events like natural disasters or domestic violence, experiencing some form of abuse or neglect, bullying, and anything else perceived as dangerous. Because of the public health concerns regarding child abuse and neglect, most research has focused on the impact of the trauma of abuse and neglect in childhood.

Ongoing research has revealed some of the impacts of childhood trauma on the brain, which can further help to understand trauma and inform treatment.

Current research has shown that child abuse can impact the brain’s volume, causing decreases in white matter in multiple areas of the brain.  The volume and structure of white matter are linked with learning. The area of the brain linked with processing emotions and cognitive ability is affected as well. Researchers concluded that experiencing abuse in early life likely has a lasting impact on connectivity in these areas of the brain, which may contribute to mood and other mental health complications experienced by those who experience trauma in childhood.

Trauma researchers have noted the long-term impacts of lack of safety in childhood in how the brain later interprets stress and responds to it. A stressful or unsafe environment in childhood that limits development.
