A significant portion of veterans with PTSD do not respond adequately to first-line treatments — a reality that has driven sustained research interest in alternative approaches, including transcranial magnetic stimulation. TMS received FDA clearance for major depressive disorder in 2008 and has since accumulated a growing body of research examining its effects on PTSD, a condition that shares significant neurobiological overlap with depression. At Oasis Therapeutics, we offer TMS Therapy Treatment at our Nashua and Concord, New Hampshire clinics and work with veterans and first responders across New England who are looking for options beyond what conventional treatment has provided.
What TMS Is and How It Works
Transcranial magnetic stimulation (TMS) is a non-invasive procedure — meaning it does not involve surgery, injections, or anesthesia — that uses magnetic fields to stimulate nerve cells in targeted regions of the brain. During a session, a magnetic coil is placed against the scalp near the forehead. The coil generates brief, focused magnetic pulses that pass through the skull and induce small electrical currents in the underlying brain tissue, activating nerve cells in the targeted area.
The brain regions most commonly targeted in TMS for mood disorders are those involved in regulating emotional responses and executive function — areas that research has consistently shown to be underactive in both depression and PTSD. By stimulating these regions repeatedly over a course of treatment, TMS promotes neuroplasticity — the brain’s ability to form and strengthen neural connections — which is understood to underlie its sustained therapeutic effects (National Institutes of Health).
TMS should not be confused with electroconvulsive therapy (ECT), a procedure that involves inducing a brief seizure under general anesthesia. TMS does not affect cognitive functions like memory, does not require anesthesia or sedation, and does not produce the systemic side effects associated with many psychiatric medications such as weight gain or sexual dysfunction (Mayo Clinic). Patients are awake and alert throughout each session and can drive themselves to and from appointments.
The Evidence for TMS in PTSD
TMS received FDA clearance for major depressive disorder and has peer-reviewed support for its use across several conditions we treat, including anxiety, OCD, and chronic pain. Its application for PTSD is an area of active and growing research, and the evidence that has accumulated supports cautious optimism. The neurobiological overlap between PTSD and depression — both involve dysregulation of the prefrontal cortex, disrupted fear-extinction pathways, and impaired emotional regulation — provides a mechanistic rationale for why TMS, which has demonstrated effectiveness in depression, may also benefit patients with PTSD.
The evidence base for TMS is grounded in its FDA-cleared application for major depressive disorder, supported by peer-reviewed research documenting the treatment’s efficacy and safety profile (National Institutes of Health). Research also demonstrates that TMS promotes neuroplasticity, strengthening the neural pathways associated with mood regulation in ways that produce lasting effects beyond the course of treatment itself (National Institutes of Health). The PTSD-specific research continues to develop, and we follow it closely as it informs our clinical approach.
For a deeper look at how TMS compares with other interventional options for depression and trauma-related conditions, see our PTSD Treatment with TMS blog post, which examines the published clinical literature in greater detail.
We present TMS for PTSD with the framing the evidence warrants: it is an emerging application with a sound neurobiological rationale, a strong safety record, and a growing clinical literature. We do not overstate what is known, and we discuss the evidence honestly with every patient during the consultation.
Why TMS Is Particularly Relevant for Veterans
Veterans with PTSD face a specific clinical challenge: they often arrive with a history of medications that have produced partial relief, significant side effects, or both — and many are reluctant to add another medication to the list. TMS is a non-medication treatment. It does not require daily pills, does not carry the systemic side effect burden of pharmacotherapy, and does not interact with medications already being taken. For veterans who have cycled through antidepressants and anti-anxiety medications without adequate relief, that profile is meaningful.
TMS is also covered by many major insurance plans, which addresses one of the most consistent barriers to care in this population. We accept United Healthcare, Blue Cross Blue Shield, Cigna, Aetna, Medicare, TRICARE, the Veterans Administration, Harvard Pilgrim, and NH Healthy Families for TMS at our Nashua and Concord clinics. For veterans receiving VA benefits or TRICARE coverage in particular, TMS represents a clinically substantive and often accessible option.

We are a veteran-owned practice. Our founders served, and our approach to veteran mental health care reflects that background directly — not in branding language, but in how we conduct evaluations, how we talk with patients about their experiences, and how we structure care for people who are accustomed to being handled generically.
What a TMS Course Looks Like at Oasis Therapeutics
Every patient begins with a consultation in which one of our clinicians reviews your full medical and psychiatric history, current medications, and symptom presentation. We determine whether TMS is clinically appropriate and, if so, establish the treatment parameters that are right for your specific case.
A standard TMS course involves sessions conducted five days a week. Each session runs between 20 and 40 minutes. During the session, you are seated comfortably in a chair while a trained technician positions the magnetic coil against your scalp. A motor threshold determination — the process of identifying the minimal magnetic pulse intensity needed to produce a small hand muscle response — is performed to calibrate the treatment to your individual neurology. This personalization matters: it ensures the stimulation is appropriately targeted and dosed for your specific brain rather than a generic protocol.
You will hear a clicking sound and feel a tapping sensation on the scalp during the session. Most patients find this tolerable and report that any initial scalp discomfort diminishes as treatment progresses. There is no recovery period after each session — you leave and return to your normal day immediately.
The most common side effects are mild scalp discomfort at the treatment site and headache, particularly in early sessions. These typically resolve quickly. Serious side effects, including seizure, are extremely rare (National Institutes of Health). We review the full side effect profile with every patient before treatment begins.
TMS Within a Broader Treatment Plan
For veterans with PTSD, TMS works most effectively as part of a comprehensive clinical approach rather than in isolation. At Oasis Therapeutics, we often discuss TMS alongside other options we offer — including Advanced Ketamine Therapy in Nashua & Concord, NH for patients with significant depressive or anxiety symptoms, and stellate ganglion block (SGB) for those whose trauma-related sympathetic nervous system overactivation may benefit from a targeted interventional approach. We also encourage all patients to maintain a relationship with a mental health therapist, as clinical treatments address the neurobiological component of PTSD while psychotherapy addresses the cognitive and behavioral dimensions.
We build individualized treatment plans rather than applying a one-size protocol. Your history, your symptom profile, your prior treatment experiences, and your preferences all factor into the conversation.
Two Barriers We Hear Often
“I don’t have time for a treatment that involves that many appointments.” This is a legitimate concern, and we hear it regularly from veterans who are managing work, family, and the general demands of life while also trying to get treatment. TMS sessions run 20 to 40 minutes and are scheduled to fit within a working week. Many patients schedule early morning or late afternoon appointments. The time commitment is real, but it is also finite — a full course of treatment has a defined endpoint, not an open-ended timeline.
Stigma around seeking mental health treatment. In service culture, the belief that seeking help signals weakness is deeply embedded and genuinely damaging. PTSD is a neurobiological condition — the same kind of medical condition as a cardiac arrhythmia or a metabolic disorder — and treating it with evidence-based clinical tools is not a departure from the values of service. We are a veteran-owned practice, and we say that because it changes the conversation in this room. Results vary by individual, and we encourage every patient to explore their options and discuss them openly with their healthcare provider.
Frequently Asked Questions
Is TMS approved for PTSD specifically? TMS received FDA clearance for major depressive disorder in 2008 and subsequently for OCD. Its use for PTSD is an emerging application supported by a growing body of research and a sound neurobiological rationale, but FDA clearance specifically for PTSD has not yet been established. We discuss this distinction honestly with every patient — TMS for PTSD is practiced within the context of its established evidence base and FDA-cleared indications, not outside it.
How long before TMS produces noticeable effects for PTSD symptoms? Effects from TMS typically develop gradually over the course of treatment rather than rapidly after a single session. Many patients begin noticing changes several weeks into the treatment course, with continued improvement through the full protocol. This differs from ketamine infusion therapy, which often produces more rapid initial effects. Individual response varies, and your progress is monitored throughout.
Can I do TMS and ketamine therapy at the same time? In some cases, combining TMS with ketamine infusion therapy or other treatments may be appropriate. This is assessed individually based on your clinical presentation, history, and goals. We discuss combination approaches during the evaluation and build a plan that reflects your specific situation rather than a fixed protocol.
Does TMS hurt? Most patients describe the procedure as tolerable. The tapping sensation on the scalp and the clicking sound of the coil are the most common experiences. Mild scalp discomfort or headache in early sessions is possible and typically diminishes as treatment progresses. TMS does not involve needles, anesthesia, or sedation.
