One Star Review

I haven’t had a one-star blog yet, so it’s about time. The Heart of Trauma: Healing the Embodied Brain in the Context of Relationships by Bonnie Badenoch is one of the more influential texts to emerge from the interpersonal neurobiology (IPNB) movement in trauma therapy. Positioned at the intersection of attachment theory, neuroscience, somatic awareness, and relational psychotherapy, the book argues that trauma is fundamentally a disruption of embodied relational integration rather than simply a dysregulated nervous system or a collection of symptoms.

Her emphasis on co-regulation, embodied safety, and the therapist’s nervous system as an active component of treatment reflects what many experienced clinicians already know intuitively: clients often heal not only because of what therapists do, but because of how therapists are. For therapists early in their careers, the book can function as an antidote to rigid technique-driven practice. Most of the job is showing up.

My primary issue is the book’s relationship to neuroscience. She draws heavily from concepts associated with interpersonal neurobiology, hemispheric integration, polyvagal theory, and relational regulation. While these frameworks are clinically influential, the empirical foundations beneath some of the claims are less robust than the book implies.

At times, the text blurs the line between established neuroscience and metaphorical neuropsychological storytelling. Concepts are frequently presented with an aura of scientific certainty despite ongoing debate within neuroscience and psychotherapy research communities. Therapists unfamiliar with the limitations of these theories may leave the book overestimating the evidentiary status of some IPNB claims. To be more succinct, she makes shit up.

The relationship is the core of therapeutic healing. She could’ve just written that one sentence instead of trying to justify it with neuroscience that doesn’t line up with the claims.
