IV Ketamine for
OCD

More than being neat —
a brain stuck in a loop

OCD is one of the most misunderstood conditions in mental health. It is not about being tidy or organized. It is not a personality quirk. OCD is a neurological condition in which the brain's error-detection system is stuck in the "on" position, generating relentless doubt, intrusive thoughts, and an overwhelming compulsion to perform rituals in a desperate attempt to find relief.

The obsessions can be about contamination, harm, symmetry, morality, relationships, or virtually anything else. They are not thoughts you want — they are thoughts you cannot stop having. The compulsions — checking, washing, counting, repeating, seeking reassurance — provide momentary relief, but the cycle always comes back stronger.

Standard treatment involves SSRIs at high doses and a specific type of cognitive behavioral therapy called Exposure and Response Prevention (ERP). These approaches help many people. But for those with treatment-resistant OCD — and roughly 40-60% of patients do not achieve adequate relief from first-line treatments — ketamine represents a genuinely new approach.

What OCD Actually Looks Like

The glutamate hypothesis of OCD

For decades, OCD research focused almost exclusively on serotonin. While serotonin plays a role, emerging evidence points to glutamate — the brain's primary excitatory neurotransmitter — as a central driver of OCD pathology. This is significant because it opens the door to treatments that work through an entirely different mechanism than traditional SSRIs.

Cortico-Striatal-Thalamic Circuit

OCD is driven by a malfunctioning circuit that loops between the cortex (where thoughts originate), the striatum (where habits and routines are processed), and the thalamus (the brain's relay station). In OCD, this circuit is hyperactive — signals loop endlessly instead of resolving, creating the subjective experience of a thought that won't go away and an action that must be repeated.

Neuroimaging studies show excessive glutamate activity in key nodes of this circuit. Ketamine modulates glutamate signaling through NMDA receptor blockade, which appears to help normalize activity in the cortico-striatal loop and break the obsessive cycle.

Rapid Onset of Relief

One of the most remarkable findings in OCD research is how quickly ketamine can reduce obsessive-compulsive symptoms. A landmark study published in the American Journal of Psychiatry found that a single ketamine infusion produced significant OCD symptom reduction within hours — an effect that lasted up to a week in many patients. For a condition where standard medications take 8-12 weeks to reach full effect, this represents a paradigm shift.

Enhanced Cognitive Flexibility

At the core of OCD is cognitive rigidity — the inability to let go of a thought, to accept uncertainty, to move on from a perceived error. Ketamine appears to enhance cognitive flexibility by promoting neuroplasticity in prefrontal brain regions, helping the brain develop new, more adaptive response patterns to the triggers that previously initiated obsessive cycles.

Treatment in a space you control

We understand that unpredictability can be particularly challenging for people with OCD. That is why we are transparent about every aspect of the treatment process.

Your journey begins with a thorough consultation where Marla reviews your OCD history, current symptoms, and previous treatments. She will explain exactly what to expect during an infusion — the timeline, the sensations, the monitoring — so there are no surprises.

Treatment typically involves a series of six infusions over two to three weeks. Each session lasts approximately 40 minutes in a private treatment suite. Marla monitors your vital signs continuously. You are in control of your environment — the lighting, the music, the temperature.

Many patients with OCD find that ketamine creates a window of enhanced flexibility where ERP and other therapeutic techniques become significantly more effective. We encourage coordination with your existing therapist to take full advantage of this neuroplastic window.
