PTSD Treatment with Ketamine & TMS in Los Angeles

When Your Nervous System Won’t Let You Move On

Trauma doesn’t stay in the past. For people living with PTSD, it lives in the body — in the sudden spike of alertness when a sound is too loud, in the way certain places or conversations feel dangerous before your mind has processed why, in the exhaustion of being constantly vigilant when there is nothing left to watch for.

This is not weakness. This is your nervous system doing exactly what it was designed to do — protecting you from a threat — long after the threat has passed. PTSD is a disorder of the fear-memory system, not a personal failing.

And for many people, the standard treatments — talk therapy, SSRIs, trauma-focused CBT — provide partial relief at best. The biology of PTSD can be stubborn in ways that conversation alone cannot fully reach.

Julian Macias, PMHNP-BC, offers ketamine infusion therapy, TMS, and integrated follow-up care specifically informed by the neuroscience of trauma. For patients who have tried other treatments and found them insufficient, this approach may represent a meaningful step forward.

Understanding PTSD: The Body That Won’t Stand Down

PTSD develops when the brain’s threat-detection system — centered in the amygdala — becomes dysregulated following traumatic experience. In people with PTSD, the amygdala remains hyperactivated long after the trauma has ended, producing the classic symptom clusters:

• Hypervigilance and hyperarousal: Constant alertness, exaggerated startle response, difficulty relaxing or sleeping, feeling always on edge
• Avoidance: Steering away from people, places, thoughts, or feelings associated with the trauma
• Intrusion: Flashbacks, nightmares, and intrusive memories that bring the trauma into the present moment involuntarily
• Negative changes in mood and cognition: Persistent shame, guilt, emotional numbness, distorted beliefs about oneself or the world

These symptoms are encoded in the brain’s architecture — in the neural pathways of fear memory and threat response. Lasting change requires something that can reach those pathways directly.

Why Traditional PTSD Treatments Fall Short for Many People

Trauma-focused therapies — including EMDR, Prolonged Exposure, and Cognitive Processing Therapy — are effective for many people with PTSD, and Julian strongly supports the role of good therapy in trauma recovery. But these approaches have meaningful limitations.

They require patients to engage directly with traumatic memory, which for many people is re-traumatizing or simply too activating to be tolerable. Dropout rates in trauma-focused therapy are high. And for patients with severe PTSD, the dysregulation of the nervous system itself can make the therapeutic process extremely difficult.

SSRIs and SNRIs — the medications most commonly prescribed for PTSD — can reduce some symptoms, particularly hyperarousal and depression comorbidity. But they do not address the core fear-memory circuitry of PTSD, and many patients achieve only modest benefit. This is where ketamine and TMS offer something genuinely different.

Ketamine for PTSD: Reaching the Fear-Memory System

Ketamine works through the glutamate system, and for PTSD specifically, this mechanism has particularly important implications.

Research suggests that ketamine promotes fear extinction — the neurological process by which the brain learns that a previously threatening stimulus is no longer dangerous. This is the same process that trauma-focused therapy aims to promote through exposure, but ketamine may accelerate it neurobiologically, lowering the threat-detection alarm that PTSD keeps stuck in the “on” position.

Ketamine also appears to dampen overactivity in the amygdala — the brain’s alarm center — which is chronically hyperactivated in PTSD. This can produce a rapid reduction in hypervigilance and hyperarousal that many patients with PTSD describe as the first meaningful relief they have felt in years.

For patients with PTSD, IV ketamine infusion therapy may also lower the threshold for engaging in trauma-focused therapy afterward. When the nervous system is less reactive, when the intrusions are quieter, therapy becomes more accessible. Ketamine and psychotherapy are not either/or — for many PTSD patients, the combination is more powerful than either alone.

TMS for PTSD: Calming the Overactive Brain

TMS for PTSD targets the dorsolateral prefrontal cortex (DLPFC) — a region that, in PTSD, often shows reduced activity relative to the hyperactivated amygdala. The DLPFC plays a critical role in regulating emotional responses, inhibiting fear reactions, and maintaining executive control over impulse and reactivity.

By stimulating the DLPFC through repeated sessions of magnetic pulses, TMS can gradually shift the balance between prefrontal regulation and amygdala reactivity — helping to restore the kind of top-down emotional control that PTSD disrupts. Clinical research on TMS for PTSD shows promising results, particularly for hyperarousal symptoms and for patients whose PTSD is comorbid with depression.

Julian’s Trauma-Informed, Integrated Approach

Julian approaches PTSD care with specific attention to what it means to treat a traumatized nervous system. This means never rushing. The initial evaluation for PTSD patients is thorough and unhurried — Julian wants to understand your full history, including what treatments you’ve tried, what helped, what made things worse, and what you are hoping for. He does not approach ketamine or TMS as procedures to be administered. He approaches them as part of a relationship.

It also means taking the integration work seriously. The period following ketamine treatment is particularly important for PTSD patients — the neuroplasticity window that opens after infusions is also a window for beginning to process trauma in a way that is less overwhelming. Julian’s 12-Week Integration Program includes PTSD-specific journaling prompts and behavioral scaffolding designed to support the processing work that ketamine makes available.

Integration for PTSD: Building New Pathways

For patients with PTSD, integration is not just a wellness add-on. It is where the recovery happens.

Ketamine opens a neuroplasticity window during which the fear-memory circuits of the brain are more malleable. For PTSD patients, this is the moment to begin — gently, with support — the process of building new associations, new emotional responses, and new narratives about safety and selfhood.

The 12-Week Ketamine Integration Program supports this work through structured journaling, AI-guided check-ins, and clinical touchpoints with Julian. For PTSD patients who are also working with a trauma therapist, the integration program can run alongside that work, creating a layered and well-supported recovery environment.
