Post-traumatic stress disorder (PTSD) — a condition defined by persistent intrusive memories, hypervigilance, emotional numbing, and physiological reactivity following traumatic experience — does not respond adequately to first-line treatment in a significant portion of the adults who complete it. That leaves a substantial population managing active symptoms not because they have avoided care, but because the treatments available to them have not been sufficient. IV ketamine therapy has produced clinically significant reductions in PTSD symptom severity in peer-reviewed trials, and at Mend The Mind in Livingston, Montana, we offer it under continuous medical supervision by a Board Certified Registered Nurse Anesthesiologist with more than a decade of clinical experience.
Why PTSD Resists Standard Treatment
PTSD is not simply a response to stress that fades with time or willpower. It is a condition in which traumatic experiences alter how the brain stores and processes threat-related information, leaving the nervous system in a state of chronic activation long after the original danger has passed. The intrusive memories, nightmares, hyperarousal, and emotional constriction that characterize PTSD are not character weaknesses — they are symptoms of a nervous system that was reshaped by overwhelming experience and has not been able to fully down-regulate since.
First-line treatments for PTSD include SSRIs (selective serotonin reuptake inhibitors), SNRIs (serotonin-norepinephrine reuptake inhibitors), and trauma-focused therapies such as cognitive processing therapy and prolonged exposure. These treatments produce meaningful improvement for many patients. For a clinically significant subset, however, response is partial — symptoms may decrease but do not resolve, or the intensity of trauma-focused processing requires a level of nervous system stabilization the patient has not yet been able to achieve. The result is a category of treatment-resistant PTSD that standard care protocols were not designed to address.
This is the population we work with at Mend The Mind. Our evaluations begin with your complete trauma and treatment history — not your diagnosis in isolation, but the full account of what you have tried, how long you tried it, and what your experience of the outcome was.

How Ketamine Addresses PTSD Through a Different Mechanism
Ketamine’s mechanism in PTSD involves the same core pathway relevant to its use in depression: NMDA receptor blockade in the glutamate system. NMDA receptors — N-methyl-D-aspartate receptors — are proteins that regulate synaptic plasticity, which is the brain’s ability to form, strengthen, and modify connections between neurons. In PTSD, neural pathways associated with fear memory can become overactivated and resistant to extinction — meaning the brain continues generating threat signals from experiences that are no longer occurring.
Ketamine’s effects on this system may help interrupt that cycle. By modulating glutamate activity, ketamine appears to support the formation of new neural connections and may reduce the strength of entrenched fear-based pathways. This is mechanistically distinct from what SSRIs and SNRIs do in PTSD — those medications target serotonin and norepinephrine primarily, leaving the glutamate system largely unaddressed. For patients who have tried multiple serotonin-targeting medications without adequate relief, this mechanistic difference is clinically relevant, not incidental.
The result is that some patients with treatment-resistant PTSD experience rapid, significant symptom reduction with IV ketamine — often within hours to days of treatment, rather than the weeks that conventional medications require.
What the Evidence Shows
The evidence base for IV ketamine in PTSD has matured considerably and now includes peer-reviewed research from major medical publications. A study published in JAMA Psychiatry found that intravenous ketamine significantly reduced PTSD symptom severity compared to a control condition — providing direct clinical evidence for IV administration specifically, the delivery method we use at Mend The Mind, in this patient population.
Research supported by the National Institutes of Health has further characterized these effects, demonstrating rapid and robust reductions in PTSD symptom severity and supporting ketamine’s potential as an effective treatment for patients who have not responded to conventional therapies. A separate body of research from the National Institutes of Health examined repeated ketamine administration in chronic PTSD and showed that multiple treatment sessions produce sustained symptom relief — findings directly relevant to our multi-session protocol structure.
These are not fringe observations or single preliminary studies. They represent a growing and peer-reviewed evidence base that has positioned IV ketamine as one of the more credible options available to patients with treatment-resistant PTSD.
Results vary by individual, and we do not represent ketamine therapy as a guaranteed outcome. What the evidence supports is that it may meaningfully help patients for whom standard treatments have not been sufficient — and that the effect can be sustained through a thoughtfully structured course of treatment.
What Treatment Looks Like at Mend The Mind for PTSD
Every PTSD treatment plan at Mend The Mind begins with a thorough evaluation conducted before any infusion is scheduled. We review your trauma history, previous medication and therapy trials, current symptoms, and treatment goals — and we give you a direct, honest assessment of whether IV ketamine therapy is appropriate for your specific situation. Not every patient is a candidate, and we are straightforward about that from the start.
IV ketamine infusions are administered in our private treatment room in Livingston by our founder Cassidy Boyer — a Board Certified Registered Nurse Anesthesiologist and PMHNP candidate completing her post-master’s training at Montana State University. Cassidy is a USAF veteran with combat deployments. That background is not decoration. It means she understands the real experience of trauma, high-demand environments, and the particular reluctance that can accompany seeking psychiatric care in communities where self-sufficiency is both a value and a survival skill.
Every session includes continuous monitoring of heart rate, blood pressure, and oxygen levels, and Cassidy is present with you throughout. Mental health infusions typically last 40 to 60 minutes. Our standard initial protocol is six infusions over two to three weeks. We monitor your response across that series and discuss what you are experiencing between sessions — how your sleep is, whether hypervigilance has shifted, what has changed and what has not.
For patients managing distance or seeking flexible maintenance support after completing an initial IV series, we prescribe ketamine troches — dissolvable lozenges for at-home use under our ongoing medical supervision. Troches can help sustain the benefits achieved through IV treatment without requiring clinic visits for every dose.
We also offer somatic psychedelic facilitation alongside ketamine sessions — body-centered support that guides attention to physical sensations, nervous system states, and the mind-body connection during treatment. This approach is particularly relevant for PTSD, where trauma is often stored in the body as chronic muscular tension, dysregulated breathing, and persistent autonomic activation that cognitive approaches alone may not fully reach. The facilitator monitors heart rate and supports nervous system regulation throughout the session, and a 30 to 45 minute integration session follows each ketamine treatment. Discuss with your provider whether this add-on is appropriate for your clinical situation.
Addressing Stigma Around Psychiatric Care
The most consistent non-financial barrier we encounter in patients with PTSD — particularly veterans, first responders, and others from high-performance professional backgrounds — is not skepticism about the treatment itself. It is the internal threshold required to seek psychiatric care at all. PTSD in these communities often coexists with cultural values around self-sufficiency, capability, and a quiet resistance to being associated with a psychiatric diagnosis or treatment. The result is delayed care, years of private management, and the compounding of a condition that responds better to earlier intervention.
We do not ask patients to abandon those values. We do ask that seeking effective treatment be separated from any implication about strength or competence. Cassidy founded this practice as someone who has lived and worked inside those professional cultures and who understands from experience that choosing evidence-based care is not a contradiction of the things that made you good at what you do. Explore your options with someone who takes both your clinical history and your hesitation seriously. We are prepared for that conversation.
Addressing Cost
Cost is a real and practical consideration for most patients, and we believe it deserves direct discussion rather than a footnote. Pricing at Mend The Mind is reviewed during your consultation rather than published on our website, because treatment plans vary and a single figure would not accurately represent what your specific situation involves. We are an out-of-network provider. Through the Osmind care management platform, every patient receives a detailed superbill following each session that can be submitted to their insurance company for potential reimbursement. We recommend contacting your insurer before starting treatment to ask specifically about your out-of-network benefits for ketamine therapy.
For veteran patients, PTSD is frequently associated with service-connected conditions and VA benefits. If that context applies to your situation, raise it during your consultation so we can discuss it clearly within the context of your overall care.
Frequently Asked Questions
Does IV ketamine for PTSD also help with depression or anxiety that co-occurs with my PTSD?
PTSD commonly co-occurs with depression, anxiety, and other conditions, and we treat all of these at Mend The Mind. Your evaluation accounts for the full clinical picture rather than a single diagnosis, and research supports ketamine’s effectiveness across these overlapping conditions. Treatment is structured based on your complete presentation.
How quickly might my PTSD symptoms change after an infusion?
Some patients report meaningful symptom reduction within hours to days of their first infusion. Others require several sessions before noticing significant change, and the full initial six-session series typically provides the clearest picture of your response. Results vary by individual, and we discuss your experience throughout the treatment process rather than waiting until the series is complete.
Is IV ketamine appropriate for complex or developmental trauma, not only combat or acute PTSD?
Yes. Research on ketamine for PTSD does not restrict its findings to a specific trauma type, and we evaluate patients with developmental trauma and complex PTSD presentations. Whether IV ketamine therapy is appropriate for your situation depends on your full clinical history — the nature of the trauma is one factor among several that we consider during your evaluation.
Do I need to pause trauma-focused therapy while doing ketamine treatment?
Not necessarily. Ketamine therapy can complement ongoing psychotherapy for many patients. We discuss your current therapeutic relationships during your evaluation and provide guidance based on your specific treatment plan. Do not make changes to any ongoing care without consulting your existing providers.
What if I have tried medications for PTSD before and had significant side effects?
Your previous medication history — including side effects that limited your ability to complete trials — is a central part of your evaluation at Mend The Mind. This information helps us understand the full picture of your treatment resistance and informs whether IV ketamine is a suitable fit. Side effect history from prior medications does not automatically disqualify you from ketamine therapy.
Key Takeaways
- PTSD frequently resists first-line treatments, leaving a substantial population managing persistent symptoms despite completed medication and therapy trials — a gap that IV ketamine therapy may help address.
- Ketamine works through NMDA receptor blockade in the glutamate system, offering a mechanistically distinct approach from SSRIs and SNRIs and one that may reach neurological pathways conventional treatments do not directly address.
- A JAMA Psychiatry study demonstrated that IV ketamine significantly reduced PTSD symptom severity compared to a control condition; research from the National Institutes of Health supports both rapid initial effects and sustained relief through repeated sessions.
- At Mend The Mind, PTSD treatment combines IV ketamine with the option of somatic psychedelic facilitation during sessions and ketamine troches for maintenance — all tailored to your clinical history, response, and practical circumstances.
- Results vary by individual. An honest evaluation of your specific history is the necessary starting point, and our team is prepared to have that conversation directly and without assumptions about your readiness.
Conclusion
PTSD that has not responded to medication and therapy is not a permanent condition for which nothing more can be done. The evidence supporting IV ketamine therapy as a treatment option for this population is peer-reviewed, growing, and relevant — and at Mend The Mind in Livingston, it is available now, delivered by a clinical team with the expertise and personal background to take your history seriously. Results vary by individual, and the right starting point is always a direct conversation about your specific situation.
