About this episode
Is it trauma? Obsessive-compulsive disorder (OCD)? Or both? Can trauma trigger OCD? Can OCD feel like trauma? In this episode, Dr. Nathaniel Van Kirk, a ADAA member and leading clinical psychologist and trauma expert, joins Gabe Howard to unpack the complex relationship between trauma and OCD. While both terms are widely used, few understand how deeply they can intertwine — or how often they’re misunderstood. Dr. Van Kirk explains why a traumatic event might trigger OCD in some people, how OCD symptoms can mimic trauma responses, and why compulsions often become misguided tools for managing fear. He also dives into the surprising statistic that up to 90% of people experience a traumatic event, and explores how our brains are hardwired to both break down and heal. Takeaways include: the difference between trauma, PTSD, and OCD why OCD isn’t usually considered a trauma disorder — but sometimes should be how clinicians decide which disorder to treat first why healing often means separating fear from fact If you’ve ever had intrusive thoughts or wanted to better understand the mental health impact of trauma, this episode is essential listening.   This episode has been sponsored by the Anxiety and Depression Association of America (ADAA). “For about 19% of individuals with OCD, they tend to have a comorbid PTSD diagnosis. I think that's much higher than what we initially thought as a field. Initially we thought it was rare, and part of the challenge is that for many years these two things were treated as silos. You were either a PTSD and trauma therapist or an OCD therapist. And very rarely did we cross over. It turns out that was not the great approach, because in reality, there's actually a lot more overlap than we thought. And finding out that it's actually a very common experience that people just didn't talk about.” ~Nathaniel Van Kirk, PhD Our guest, Nathaniel Van Kirk, PhD, is a licensed clinical psychologist, specializing in severe anxiety disorders, obsessive compulsive disorder (OCD), and trauma/PTSD.
