Childhood trauma and the brainChildhood trauma and the brain
All In The Mind
What we see, hear, and feel as a child affects us later in life—and our brain is changed by childhood traumas. A leading Canadian psychiatrist is working to understand how childhood harm can impair brain development and affect mental health, in the hope of effective treatment. And we hear about an intervention which can improve educational outcomes for vulnerable children.

Childhood Trauma, the Brain, and Giving Vulnerable Kids a Better Chance
Episode Overview
- Early childhood trauma can alter how genes are regulated in the brain, increasing the risk of behavioural problems and suicide.
- Dissociation, including multiple identities, can function as a protective response to extreme abuse, and can be addressed through long-term therapy.
- Current treatments for trauma-related problems rely on general medications and talking therapies, which help many but have limited effectiveness.
- Future research aims to develop more targeted interventions, including approaches that directly address impulsivity and core behavioural difficulties.
- Intensive, attachment-focused early education programmes can significantly improve cognitive scores and reduce social-emotional problems in high-risk children.
“So these memories are actually kept contained, like in a sealed unit within each part of me.”
What can we learn from those who have battled addiction? This episode of All In The Mind pulls focus on childhood trauma, how it reshapes the brain, and what that means for mental health later in life. You’ll first hear the striking story of Rhonda Macken, whose extreme childhood abuse led to dissociative identity disorder.
She describes creating around 200 different personalities as a way for her brain to shield her from unbearable experiences: “So these memories are actually kept contained, like in a sealed unit within each part of me.” Her eventual recovery through extensive therapy shows how, even after severe harm, change and healing are possible. Canadian psychiatrist Professor Gustavo Turecki then talks through how early trauma can alter the brain at a molecular level.
He explains that the brain is “plastic”, constantly adapting to experience, and that abuse in childhood can tweak how genes are regulated, increasing risks such as behavioural dysregulation and suicide later on. He also touches on epigenetics, the idea that experience can influence how genes work, and the possibility (still unproven) that some effects of trauma could be passed between generations. The second half shifts to what can be done right now for vulnerable children.
Associate Professor Bridget Jordan outlines the Early Years Education Program, an intensive, evidence-informed early learning environment for very high-risk children. With qualified educators, small groups, strong attachment-based relationships and embedded infant mental health support, the program has shown promising results, including improved IQ scores and far fewer social-emotional problems needing clinical attention.
This episode blends hard science, real-life trauma stories and practical social work to ask a simple but vital question: how can we give children exposed to abuse and neglect the best chance of a safer, healthier future? If you’re curious about how early experiences echo through the brain and life, and what can be done to change that echo, this one’s worth your time.
