Explore the hippocampus’s role in trauma. Learn how therapy helps integrate fragmented memories and restore narrative coherence.

Introduction

The hippocampus, critical for memory integration, is profoundly affected by trauma. Neuroimaging shows reduced hippocampal volume in PTSD, contributing to fragmented, intrusive memories.

This blog explores how therapies like EMDR, CPT, and narrative exposure restore hippocampal functioning.

The Hippocampus and Trauma

  • Role: Encodes contextual memory (time/place).
  • Trauma impact: Memories remain fragmented, intrusive, and unintegrated.
  • Symptom link: Flashbacks feel like the trauma is happening “now.”

Case Example

James, combat veteran, experienced flashbacks triggered by helicopters. EMDR helped his hippocampus integrate the memory into the past, reducing distress.

Therapy Strategies

  • EMDR: Supports memory reconsolidation.
  • CPT: Reframes trauma-related meanings.
  • Narrative therapy: Restores coherence to life story.

Clinical Takeaways

  • Teach clients: “Your brain stored the memory without time stamps.”
  • Emphasize safety and grounding during memory work.

Conclusion

Understanding the hippocampus helps therapists explain why trauma feels so present—and how therapy helps move it into the past.
