Neuroscience of OCD: Understanding the CSTC Loop

OCD is often reduced to intrusive thoughts and ritualistic behaviors, but let's be real—it’s so much more than that. These are just the surface-level symptoms of a much deeper survival mechanism rooted in childhood brain development and trauma stored in the nervous system. This limited view is part of what keeps so many stuck in the cycle of OCD, struggling to find true relief. But here’s the truth: if we address the root of OCD, we can begin to heal and, over time, reduce those protective outputs like intrusive thoughts and rituals.

In this episode, Elisabeth and Jennifer bring Matt Bush back to the podcast for a powerful conversation about how OCD is a protective mechanism and how we can treat it by working directly with the nervous system. They explore the brain structures involved in OCD, how it affects our nervous system, and where it all begins in childhood. They also dive into why OCD leads to compulsive behaviors and the emotions that fuel them. Plus, they’ll break down the latest scientific studies on OCD treatment and share why and how it forms.

What if we could start viewing OCD as a feature, not a flaw? By doing this, we can begin to strip away the shame and truly understand it as the protective response it is—one that’s embedded in our nervous system and can actually be worked with. It doesn’t have to be a life sentence. There’s a way through OCD, and we’re here to show you how.

If you or someone you know is struggling with OCD and is ready for answers, be sure to tune in and share this episode. Let’s break the stigma and take the first step toward healing together.
