『The Body Keeps the Score』要約

In *The Body Keeps the Score*, psychiatrist Bessel van der Kolk argues that trauma is stored not just in the mind but in the body and nervous system, reshaping how survivors think, feel, and react long after the event. Drawing on decades of clinical work and research, he proposes that talk therapy alone often fails because trauma lives in implicit memory and physiological arousal rather than in narrative recall. The book is organized around three broad areas: the neuroscience of trauma, the ways trauma manifests across the lifespan, and paths to recovery. Van der Kolk explores how traumatic stress affects the brain’s alarm system, particularly the amygdala, hippocampus, and prefrontal cortex, and how it disrupts the stress hormones that normally restore equilibrium. He describes how survivors may oscillate between hyperarousal (panic, rage, hypervigilance) and hypoarousal (numbing, dissociation, collapse), and he connects these patterns to conditions such as PTSD, depression, and borderline personality disorder. He also examines early attachment and developmental trauma, including adverse childhood experiences, and critiques the tendency to label survivors with multiple diagnoses rather than addressing the underlying injury. Recovery, he argues, requires helping the body feel safe again. He discusses approaches such as yoga, mindfulness, EMDR, neurofeedback, theater, and other body-based or rhythmic therapies, alongside more traditional psychotherapy. Throughout, he uses patient histories and research findings to illustrate how trauma can be renegotiated somatically and relationally, emphasizing that healing depends on restoring a sense of agency, connection, and safety in the present.
