Why OCD and Panic Attacks Overlap
To understand the connection, it helps to understand what each condition is doing in the brain. OCD — obsessive-compulsive disorder — is characterized by recurring, unwanted thoughts called obsessions, and repetitive behaviors or mental acts called compulsions that a person feels driven to perform in response to those thoughts (Singh et al., 2023). Panic disorder involves recurrent, unexpected panic attacks: discrete episodes of intense fear that peak within minutes and include physical symptoms like pounding heart, shortness of breath, dizziness, or a feeling of losing control.
These are classified as separate conditions, but they share significant neurobiological territory. Both involve dysregulation in anxiety-processing circuits, and research has found that patients with OCD and comorbid panic disorder show higher overall anxiety levels and more complex symptom profiles than those with either condition alone (Lochner et al., 2014). The obsessions that define OCD are inherently threatening — they generate a sense of danger or catastrophe that can, in some people, trigger the same alarm response that produces a panic attack. In this way, OCD can act as a chronic engine of panic.
There is also a feedback loop worth understanding. Panic attacks are frightening, and people who experience them often develop anticipatory anxiety — fear of having another attack — which can worsen OCD compulsions as a person tries to neutralize the threat. A person who already engages in checking behaviors, for example, may check more frequently or intensely after a panic episode in an attempt to feel safe. The two conditions reinforce each other in ways that can be difficult to address if only one is being treated.
The Neurobiology Behind Both Conditions
Research into OCD has increasingly focused on cortico-striato-thalamo-cortical (CSTC) circuitry — the loop between the brain’s prefrontal cortex, striatum, and thalamus that governs decision-making, threat assessment, and the suppression of unwanted thoughts (Singh et al., 2023). When this circuit misfires, the brain has difficulty filtering out intrusive thoughts and signals the body to respond as if those thoughts represent real danger. That threat signal is mediated in part by the same neurotransmitter systems — serotonin, dopamine, and glutamate — involved in panic responses.
The comorbidity between OCD and panic disorder appears to reflect overlapping vulnerability in these shared systems rather than two entirely separate disease processes. Bienvenu and colleagues (2012), analyzing family data from the OCD Collaborative Genetics Study, found that anxiety disorders — particularly agoraphobia and generalized anxiety — were substantially more common in OCD-affected individuals and their first-degree relatives than in controls, suggesting a shared familial and biological predisposition. That biological overlap matters when it comes to treatment: addressing only one condition while the other continues to drive the underlying neural dysregulation often produces incomplete results.
When Standard Treatments Fall Short
First-line treatments for OCD — typically selective serotonin reuptake inhibitors (SSRIs) and cognitive-behavioral therapy (CBT) with a specific component called exposure and response prevention (ERP) — work well for many people. The same is true for panic disorder, which responds to SSRIs and CBT. But when both conditions are present together, treatment becomes more complicated. Some patients find that their OCD symptoms improve with SSRIs while panic attacks persist, or vice versa. Others find that neither responds adequately.
This is the treatment-resistant picture we see frequently at InfuseRVA. Patients who come to us have often already tried multiple medications and rounds of therapy. They are not failing treatment because they are not trying — they are dealing with a neurobiological pattern that has not responded to the pathways those treatments target. That distinction matters, and it informs the approach we take.
We want to address something that keeps people from seeking additional help: the concern that pursuing a different treatment option means abandoning the progress already made with a therapist or prescriber. It does not. We strongly encourage every patient to maintain those existing relationships. Ketamine therapy, when appropriate, is meant to work alongside the treatment you already have — not replace it. In fact, we have found that the neuroplasticity effects of ketamine may make ongoing therapy more productive for some patients.
How Ketamine Therapy May Help
Ketamine infusion therapy works differently from SSRIs. Rather than targeting serotonin, ketamine acts on the glutamate system — specifically by blocking N-methyl-D-aspartate (NMDA) receptors. This triggers a cascade of neurological events that includes the release of brain-derived neurotrophic factor (BDNF), a protein that supports the growth and repair of neural connections (Krystal et al., 2024). The result is a rapid enhancement of neuroplasticity — the brain’s capacity to form new pathways — that may allow patients to break out of the rigid, distress-driven patterns that characterize both OCD and panic disorder.
For patients with OCD, early research has explored whether ketamine’s effects on glutamate signaling may interrupt the hyperactive CSTC circuits driving obsessions and compulsions. For panic, the reduction in overall threat sensitivity and the window of neuroplasticity that follows ketamine treatment may allow the nervous system to respond differently to previously triggering stimuli. Results vary by individual, and ketamine is not appropriate for everyone. Every patient at our South Chesterfield clinic undergoes a thorough evaluation by our medical team before any treatment is considered.
Talking Honestly About Cost and Access
We know that cost is a real barrier for many people considering ketamine therapy. IV ketamine infusion therapy is not covered by most insurance plans, as it is still considered an investigational treatment for mental health conditions. We are upfront about this from the beginning of your consultation because we believe you deserve to make an informed decision. Our team will walk you through self-pay options before you commit to anything.
We also hear from patients who have delayed reaching out because they are not sure they qualify, or because they are worried about the time commitment involved. Our consultations are designed to answer both of those questions clearly. Our Monday–Friday schedule at 16021 Kairos Rd., Suite A in South Chesterfield is built around working-hour access, and we work with patients across the greater Richmond metro area including Chester, Mechanicsville, and Powhatan. If you have been wondering whether your situation warrants an evaluation, the answer is almost always: come talk to us first.
Frequently Asked Questions
Can OCD cause panic attacks?
OCD does not directly cause panic attacks, but the two conditions frequently co-occur and may worsen each other. The intrusive, threatening nature of OCD obsessions can activate the same alarm response that produces panic, and the distress of recurring panic episodes can intensify compulsive behaviors. Research suggests co-occurrence rates between 15% and 20% in clinical populations (Lochner et al., 2014).
How is treating OCD with panic disorder different from treating either alone?
When both conditions are present, treatment needs to account for the way they interact. Standard CBT protocols for OCD may need to be adapted when panic attacks are also occurring, and medication decisions become more nuanced. Patients with co-occurring OCD and panic disorder tend to present with higher anxiety and more complex symptom profiles, which is one reason treatment-resistant cases benefit from a more comprehensive evaluation.
Is ketamine FDA-approved for OCD?
IV ketamine infusion therapy is not currently FDA-approved specifically for OCD — it is used off-label for this purpose, as it is for most mental health applications. SPRAVATO® (esketamine nasal spray) is FDA-approved specifically for treatment-resistant depression. If you are exploring ketamine for OCD, discuss your full history with our medical team so we can evaluate whether it may be appropriate for your situation.
Will I have to stop my current OCD medications to try ketamine?
Not necessarily. Many patients continue their existing medications alongside ketamine therapy, though any medication decisions are made on a case-by-case basis by your medical team. We coordinate with your existing prescriber when appropriate and do not make changes to your medications without that conversation.
What should I expect at an initial consultation?
Your initial consultation at InfuseRVA involves a thorough review of your symptom history, prior treatment attempts, current medications, and overall health. Our medical team will ask detailed questions about your OCD and panic symptoms and will explain whether ketamine therapy may be appropriate for your specific picture. You will leave with a clear answer about your options — no pressure, no commitments required.
Key Takeaways
- OCD and panic disorder co-occur at clinically significant rates, with research documenting lifetime prevalence of panic disorder in up to 20% of OCD patients, suggesting shared neurobiological pathways rather than coincidence.
- Both conditions involve dysregulation in overlapping brain circuits, particularly those governing threat response and the filtering of intrusive thoughts, which is why treating only one condition often produces incomplete results.
- When standard treatments — SSRIs and CBT — have not produced adequate relief, the persistence of symptoms may reflect neurobiological patterns those treatments do not directly address.
- Ketamine infusion therapy targets the glutamate system rather than serotonin, promoting neuroplasticity that may help interrupt the rigid distress-driven patterns underlying both OCD and panic disorder; results vary by individual.
- A thorough medical evaluation is the necessary first step — at InfuseRVA, we assess whether ketamine therapy is appropriate for your specific situation before any treatment begins.
If OCD and panic attacks have both been part of your experience and standard treatments have not given you the relief you were hoping for, that history is worth taking seriously. Call us at804-895-4636 or request a consultation through our website to talk with our medical team in South Chesterfield. We will give you an honest assessment of your options and what the path forward might look like for you.
